Effect of mouth breathing on upper airway structure in patients with obstructive sleep apnea / 临床耳鼻咽喉头颈外科杂志

Objective:To compare the changes of morphology of pharynx in patients with obstructive sleep apnea hypopnea syndrome （OSAHS） and healthy individuals during oral or nasal breathing, and explore the relevant influencing factors. Methods:Twenty-nine adult patients with OSAHS and 20 non-snoring controls underwent MRI to obtain upper airway structural measurements while the subjects were awake and during mouth breathing with a nasal clip.The following were analyzed. ①The changes of upper airway structure of oral and nasal respiration in non-snoring control/OSAHS patients were observed; ②The differences and influencing factors of upper airway structure changes between OSAHS patients and controls were compared during breathing. Results:The control group consisted of 15 males and 5 females, with an apnea-hypopnea index （AHI）<5 events/h, while the OSAHS group comprised 26 males and 3 females with an AHI of 40.4±23.1 events/h and the mean lowest arterial oxygen saturation （LSaO2） was 79.5% ±10.0%. In the both groups, the vertical distance between the mandible and the posterior pharyngeal wall decreased （P<0.05）; The long axis of tongue body decreased （P<0.05）, and the contact area between tongue and palate decreased. There was no significant change in the total volume of the retropalatine（RP） and retroglossal（RG） airway in the control group （P>0.05）. However, the minimum cross-sectional area and volume of the RP airway in OSAHS decreased （P<0.001）. The lateral diameters of uvula plane in OSAHS decreased during mouth breathing, which was contrary to the trend in the control group （P=0.017）. The AHI of patients was positively correlated with the reduction of the volume of the RP airway during oral breathing （P=0.001）; The reduction of the distance between the mandible and the posterior pharyngeal wall was positively correlated with the length of the airway （P<0.001）. Conclusion:Mouth breathing leads to the shortening of the long axis of the tongue, the reduction of the contact area between the soft palate and the tongue, vertical distance between the mandible and the posterior pharyngeal wall, and the cross-sectional area of the epiglottis plane. These changes vary between OSAHS patients and controls. During mouth breathing, the diameters, areas and volumes of the RP area decreased, and were more significant in severe cases.

Planificación quirúrgica de colgajo faríngeo a medida para insuficiencia velofaríngea secundaria a fisura de paladar: reporte de caso y revisión de literatura / Surgical planning of a tailor-made pharyngeal flap for velopharyngeal insufficiency secondary to a cleft palate: case report and literature review

Resumen La insuficiencia velofaríngea (IVF) es una de las principales secuelas estructurales tras la palatoplastía primaria en casos de fisura de paladar. La IVF se caracteriza por la ausencia de tejido suficiente para lograr un cierre adecuado del mecanismo velofaríngeo durante el habla, lo que conlleva a una resonancia hipernasal y la emisión nasal de aire durante la producción de sonidos orales. Al respecto, el tratamiento ideal para corregir la IVF es quirúrgico, dentro de los cuales el colgajo faríngeo de pedículo superior es uno de los procedimientos más utilizados en nuestro país. Para su realización es fundamental determinar el ancho necesario, lo cual puede ser determinado mediante una videofluoroscopía multiplano (VFMP). Por esto, con el objetivo de potenciar el trabajo multidisciplinario en la corrección quirúrgica de la IVF, a continuación, se presentan los procedimientos de evaluación fonoaudiológica, videonasofaríngoscopía flexible y videofluoroscopía multiplano utilizados para la planificación quirúrgica de un colgajo faríngeo en un adolescente chileno diagnosticado con IVF secundaria a fisura palatina operada. Además, se describe el uso de la VFMP en la planificación quirúrgica del colgajo faríngeo mediante una revisión de literatura.

Abstract Velopharyngeal insufficiency (VPI) is one of the main structural sequelae after primary palatoplasty in cases of cleft palate. VPI is characterized by the absence of sufficient tissue to achieve adequate closure of the velopharyngeal mechanism (VFM) generating hyper-nasal resonance and nasal emission during the production of oral sounds. In cases of cleft palate, the ideal treatment to correct VPI is surgery. The upper pedicle pharyngeal flap is one of the most widely used procedures. To plan it, is essential to determine the appropriate width, which can be determined by means of multiplane videofluoroscopy (MPVF). For this reason, and with the aim of promoting multidisciplinary approach in the surgical correction of VPI, the following procedures such as speech and language evaluation, flexible videonasopharyngoscopy and multiplane videofluoroscopy used for the surgical planning of a pharyngeal flap, in a Chilean adolescent diagnosed with VPI secondary to operated cleft palate, will be presented. In addition, the use of MPVF in pharyngeal flap surgical planning is described through a literature review.

Efficacy of relocation and expansion pharyngoplasty by suspension sutures in the treatment of OSAHS with soft palate oropharyngeal obstruction / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the efficacy of relocation and expansion pharyngoplasty by suspension sutures in the treatment of obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: Seventy-three patients(including 60 males and 13 females) with OSAHS admitted to the department of otorhinolaryngology of our hospital in recent two years were retrospectively analyzed. All the patients had velopharyngeal obstructionevaluated by electronic endoscopic Müller test and were divided into control group (34 cases) and observation group (39 cases). The patients in the control group were performed modified uvulopalatopharyngoplasty, while those in the observation group were performed relocation and expansion pharyngoplasty by suspension sutures.The scores of ESS, AHI and LSaO2 before and after treatment were collected and compared. Results: The total effective rate of the observation group was 94.87%, which was significantly higher than 79.41% of the control group. The AHI was lower and LSaO2 value was higher (χ2=-1. 896,-1. 968,P<0.05)in the observation group. The sleeping symptoms and quality of life of the two groups were significantly improved. The ESS score of the observation group was decreased more significantly than that of the control group after treatment, and the difference was statistically significant (χ2=-1.451,P<0.05). The incidence of foreign body sensation in pharynx of the observation group (89.74%) was higher than that of the control group (55.88%), and the postoperative bleeding and postoperative recurrence rate (0.00%, 2.56%) was lower than that of the control group (8.82%, 14.70%)with statistical significance (χ2=4.738,4.249,4.119,P<0.05).The incidence of transient nasopharyngeal reflux in both groups was low and statistically insignificant (χ2=0.629,P>0.05). Conclusions: Preoperative strict screening of indications plays an important role in the selection of palatopharyngeal surgery methods and curative effect. Relocation and expansion pharyngoplasty by suspension sutures can improve the clinical efficacy of OSAHS with better safety and less recurrence.

INTRODUCCIÓN: La planificación de cirugías para el manejo del síndrome de apneahipopnea obstructiva del sueño (SAHOS) ha incrementado su precisión desde la introducción de la endoscopía del sueño inducido por fármacos (DISE). OBJETIVO: Evaluar la técnica de faringoplastía de reposición con suturas barbadas (BRP) para el colapso velofaríngeo y/o de paredes laterales orofaríngeas evaluado mediante DISE en pacientes con SAHOS. MATERIAL Y MÉTODO: Ochenta y ocho pacientes fueron evaluados para cirugía mediante antropometría, escala de somnolencia de Epworth (ESS) y poligrafía respiratoria. Veinte y seis de 88 pacientes fueron seleccionados. De los 26, 14 accedieron al tratamiento quirúrgico, el que se seleccionó en base a la DISE. En todos los casos, se realizó BRP. RESULTADOS: A los 3 meses de la cirugía hubo mejoría en 10/14 pacientes (criterios de Sher, disminución del índice de apnea-hipoapnea a <20 o 50% del basal). La ESS bajó en promedio de 12 a 5 puntos (p <0,05). No se reportaron incidentes en el posoperatorio y no han ocurrido eventos adversos. CONCLUSIÓN: La técnica de BRP es una técnica sencilla y útil para la expansión anterior y lateral del paladar blando y orofaringe, con una tasa de éxito similar en esta cohorte a la reportada internacionalmente.

INTRODUCTION: Surgical planning for the management of obstructive sleep apneahypopnea syndrome (OSAHS) has changed since the introduction of drug induced sleep endoscopy (DISE). AIM: To evaluate the technique of barbed sutures reposition pharyngoplasty (BRP) for velopharyngeal collapse and/or oropharyngeal lateral walls after DISE evaluation in OSAHS patients. MATERIAL AND METHOD: 88 patients were evaluated for surgery by anthropometry, Epworth sleepiness scale (ESS) and respiratory polygraphy. 26 of 88 patients were selected. Of the 26, 14 agreed to surgical treatment, which was selected on DISE findings. In all cases, BRP was performed. RESULTS: Three months after surgery there was improvement in 10/14 patients (Sher criteria, apnea-hypopnea index reduction at <20 or 50% of baseline). The ESS improved on average 12 to 5 (p <0.05). No incidents were reported in the post-operative period and no adverse events were reported. CONCLUSION: The BRP technique is a simple and useful technique for the anterior and lateral expansion of the soft palate and oropharynx, with a similar success rate in this cohort to that internationally reported.

Lateral-Expansion Pharyngoplasty: Combined Technique for the Treatment of Obstructive Sleep Apnea Syndrome

Abstract Introduction Obstructive sleep apnea syndrome (OSAS) is a multifactorial disease characterized by episodes of partial or complete collapse during sleep of different regions of the upper airway. Surgery for OSAS evolved with the introduction of different techniques, considering new surgical concept of reconstruction of the upper airway. Objective To retrospectively evaluate the effectiveness of a new approach aimed at reducing pharyngeal collapse by combining two surgical techniques: lateral and expansion pharyngoplasty. Methods We reviewed the medical records of 38 patients with OSAS undergoing lateral/expansion pharyngoplasty from January 2012 to December 2016. The following data were collected: patient age, gender, and pre- and postoperative body mass index (BMI), Epworth sleepiness scale (ESS) scores, snoring visual analogue scale (VAS) scores, and polysomnography (PSG) results. Results The PSG results showed a significant reduction in the apnea/hypopnea index (AHI) from 22.4 ± 27.3 events/h preoperatively to 13.6 ± 17.9 events/h postoperatively (p = 0.009), with postoperative AHI reduction greater than 50% in 63.2% of the patients. There was also a significant reduction in the microarousal index (19.5 ± 22.6 vs 11.0 ± 13.4 events/h; p = 0.001) and in the minimum oxygen saturation (82.6 ± 10.3 vs 86.9 ± 11.1; p = 0.007). Conclusions Lateral-expansion pharyngoplasty represents a new surgical strategy for the treatment of OSAS in patients with palatal collapse by combining two different techniques: lateral and expansion pharyngoplasty. The two techniques, performed as a one-stage procedure, led to improvements in excessive daytime sleepiness, snoring, and PSG respiratory parameters by acting on lateral and retropalatal collapse, produc- ing favorable results with good applicability in otolaryngology clinical practice.

Total Laryngectomy with Horizontal Mechanical Closure of the Pharyngoesophagectomy: Evaluation of the Effectiveness in Elderly Patients

Abstract Introduction The main modalities of surgical treatment for laryngeal cancer include transoral laser microsurgery (TLM), open preservation surgery, and total laryngectomy (TL). In the elderly, for the presence of comorbidities, the surgical approach more appropriate in many cases remains TL. The use of a stapler for the closure of the esophagus has been introduced to reduce surgical time and postoperative complications such as pharyngocutaneous fistula (PCF). Objective In the present study, we have evaluated the effectiveness of the use of the horizontal mechanical pharyngoesophageal closure in patients who underwent TL. Methods This nonrandomized study was performed on consecutive patients with histopathologically proven squamous cell endolaryngeal carcinoma. The TLwas performed using a linear stapler to mechanically suture the pharyngotomy using the semiclosed technique. Results A total of 33 patients underwent TL, and 13 of themunderwent neck dissection. A total of 15 patients (45.4%) were ≤70 years old, and 18 were > 70 years old. Analyzing the results in relation to age, patients > 70 years old showed tumors at an earlier stage than those aged ≤70 years old. Furthermore, in this group there was a greater number of patients who had comorbidities (p = 0.014). In total, we had 2 (6%) cases of PCF in 6.6% in the group ≤70 years old, and in 5.5% of the group > 70 years old (p = 1.00). Conclusions The use of the stapler for the horizontal closure of the pharyngoesophagectomy in the patients subjected to TL is proven to be useful and safe even when used in elderly patients.

Características posoperatorias de la faringoplastia combinada con amigdalectomía en comparación con la amigdalectomía en niños con síndrome obstructivo de apnea del sueño / Postoperative characteristics of combined pharyngoplasty and tonsillectomy versus tonsillectomy in children with obstructive sleep apnea syndrome

Objetivo. Identificar las ventajas posoperatorias de la amigdalectomía en conjunto con la faringoplastia en comparación con la amigdalectomía sola en niños con apnea obstructiva del sueño. Métodos. En un estudio prospectivo observacional, los pacientes que cumplían con los criterios del estudio fueron asignados aleatoriamente a dos grupos: el grupo de amigdalectomía y faringoplastia, y el grupo de solo amigdalectomía. En ambos grupos, también se practicó adenoidectomía a los pacientes con vegetaciones. Se compararon los procesos de cicatrización en la herida faríngea y las proporciones hemorrágicas. Además, se evaluó la función velofaríngea posoperatoria. Resultados. La faringoplastia junto con la amigdalectomía se practicó en 328 niños con apnea obstructiva del sueño debido a hipertrofia amigdalina, y la amigdalectomía sola, en 275 niños. Estas cohortes no mostraban diferencias demográficas significativas. Por otro lado, se encontró que la pérdida de sangre fue significativamente menor en el grupo que recibió amigdalectomía y faringoplastia (p < 0,01), y el proceso de cicatrización fue notablemente más breve. La función velofaríngea posoperatoria no resultó afectada. Conclusiones. En comparación con la amigdalectomía, la amigdalectomía junto con la faringoplastia redujeron la duración del proceso de cicatrización y la pérdida de sangre; no obstante, las complicaciones posoperatorias no aumentaron. En nuestra opinión, la combinación de faringoplastia y amigdalectomía reúne un gran potencial en el tratamiento de los niños con apnea obstructiva del sueño.

Purpose. The study aims to identify the postoperative advantages of tonsillectomy in conjunction with pharyngoplasty and tonsillectomy alone in children with obstructive sleep apneas. Methods. In a prospective observational study, patients who met the study criteria were randomly divided into two groups: tonsillectomy and pharyngoplasty group, and tonsillectomy alone group. In both groups, adenoidectomy was also performed in patients with adenoid hypertrophy. Differences in their healing processes in the pharyngeal wound and their hemorrhage proportions were compared. Furthermore, postoperative velopharyngeal function was also assessed. Results. Pharyngoplasty together with tonsillectomy was performed in 328 children with obstructive sleep apnea from tonsillar hypertrophy, and tonsillectomy was performed in 275 children. These cohorts did not reveal any significant demographic differences between groups. Furthermore, blood loss was found to be significantly decreased in the tonsillectomy and pharyngoplasty group (P <0.01), and the healing process was markedly shorter. Postoperative velopharyngeal function was not affected. Conclusions. Tonsillectomy in conjunction with pharyngoplasty reduced the duration of the healing process and blood loss, compared with tonsillectomy alone; however, postoperative complications did not increase. We consider pharyngoplasty in conjunction with tonsillectomy has great potential in the treatment of children with obstructive sleep apnea.

Pharyngo-ileo-colo-anastomosis with micro-vascular blood supply augmentation for esophago-gastric replacement due to esophago-gastric necrosis after caustic ingestion / Faringo-íleo-colo-anastomose com suprimento sanguíneo microvascular para substituição esofagogástrica por necrose esofagogástrica após ingestão cáustica

ABSTRACT Background : Complete esophago-gastric necrosis after caustic ingestion is a challenging surgical scenario for reconstruction of the upper digestive transit. Aim : To present a surgical technique for reconstruction of the upper digestive tract after total esophagectomy and gastrectomy due to esophageal and gastric necrosis Method: The transit was re-established by means of a pharyngo-ileo-colic interposition with microsurgical arterial and venous anastomosis for augmentation of blood supply. Colo-duodeno-anastomosis and ileo-transverse colic anastomosis were performed for complete digestive transit reconstruction. Result: This procedure was applied in a case of 41 years male attempted suicide by ingesting alkali caustic liquid (concentrated sodium hydroxide). Total necrosis of the esophagus and stomach occurred, which required initially total esophago-gastrectomy, closure at the level of the crico-pharyngeal sphincter and jejunostomy for enteral feeding with a highly deteriorated quality of life . The procedure was performed later and there were no major early and late postoperative complications and normal nutritional conditions were re-stablished. Conclusion: The procedure is feasible and must be managed by multidisciplinary team in order to re-establish a normal quality of life.

RESUMO Racional: A necrose esofagogástrica completa após ingestão cáustica é um cenário cirúrgico desafiador para a reconstrução do trânsito digestivo alto. Objetivo: Apresentar uma técnica cirúrgica para reconstrução do trato digestivo superior após esofagectomia total e gastrectomia por necrose esofágica e gástrica. Método: O trânsito foi restabelecido por interposição faringo-íleo-cólica com anastomose arterial e venosa microcirúrgica com aumento do suprimento sanguíneo. Adicionalmente, anastomose colo-duodeno-anastomótica e íleo-transversa foram realizadas para reconstrução completa do trânsito digestivo. Resultado: Este procedimento foi aplicado em um homem de 41 anos com tentativa de suicídio pela ingestão de líquido cáustico alcalino (hidróxido de sódio concentrado). Ocorreu necrose total do esôfago e do estômago, o que exigiu inicialmente esofagogastrectomia total, fechamento ao nível do esfíncter cricofaríngeo e jejunostomia para alimentação enteral produzindo qualidade de vida altamente deteriorada. O procedimento foi realizado mais tardiamente e não houve maiores complicações pós-operatórias precoces e tardias e condições nutricionais normais foram restabelecidas. Conclusão: O procedimento é viável e deve ser manejado por equipe multidisciplinar a fim de restabelecer a qualidade de vida normal.

Surgical outcome of pharyngeal flap surgery and intravelar veloplasty on the velopharyngeal function / Resultado cirurgico do retalho faringeo e da veloplastia intravelar sobre a funcao velofaringea

PURPOSE: To investigate the postoperative outcomes of pharyngeal flap surgery (PF) and secondary palatoplasty with intravelar veloplasty (IV) in the velopharyngeal insufficiency management regarding nasalance scores and velopharyngeal area. METHODS: Seventy-eight patients with cleft palate±lips submitted to surgical treatment for velopharyngeal insufficiency, for 14 months on an average, were evaluated: 40 with PF and 38 with IV, of both genders, aged between 6 and 52 years old. Hypernasality was estimated by means of nasalance scores obtained by nasometry with a cutoff score of 27%. The measurement of velopharyngeal orifice area was provided by the pressure-flow technique and velopharyngeal closure was classified as: adequate (0.000-0.049 cm2), adequate/borderline (0.050-0.099 cm2), borderline/inadequate (0.100-0.199 cm2), and inadequate (≥0.200 cm2). RESULTS: Absence of hypernasality was observed in 70% of the cases and adequate velopharyngeal closure was observed in 80% of the cases, in the PF group. In the IV group, absence of hypernasality was observed in 34% and adequate velopharyngeal closure was observed in 50% of the patients. Statistically significant differences were obtained between the two techniques for both evaluations. CONCLUSION: PF was more efficient than the secondary palatoplasty with IV to reduce hypernasality and get adequate velopharyngeal closure. .

OBJETIVO: Investigar os resultados cirúrgicos do retalho faríngeo (RF) e da palatoplastia secundária com veloplastia intravelar (VI) no tratamento de indivíduos com insuficiência velofaríngea (IVF) secundária quanto ao escore de nasalância e à área velofaríngea. MÉTODOS: Foram avaliados 78 pacientes com fissura de palato±lábio submetidos ao tratamento cirúrgico da IVF há 14 meses, em média, sendo 40 com RF e 38 com VI, de ambos os sexos, faixa etária de seis a 52 anos. A hipernasalidade foi estimada a partir da medida de nasalância obtida por meio da nasometria, considerando-se o escore de 27% como limite de normalidade. A medida da área do orifício velofaríngeo foi obtida por meio da técnica fluxo-pressão, sendo o fechamento velofaríngeo classificado em: adequado (0,000-0,049 cm2); adequado/marginal (0,050-0,099 cm2); marginal/inadequado (0,100-0,199 cm2); e inadequado (≥0,200 cm2). RESULTADOS: Ausência de hipernasalidade foi observada em 70%, e fechamento velofaríngeo adequado em 80% dos casos no grupo RF. No grupo VI, ausência de hipernasalidade foi observada em 34% e fechamento velofaríngeo adequado em 50% dos casos. Diferenças estatisticamente significantes foram obtidas entre as duas técnicas cirúrgicas nas duas modalidades de avaliação. CONCLUSÃO: A cirurgia de retalho faríngeo foi mais eficiente do que a palatoplastia secundária com veloplastia intravelar na redução da hipernasalidade e na adequação do fechamento velofaríngeo. .

Evolução da deglutição na faringoplastia lateral com preservação do estilofaríngeo / Evolution of swallowing in lateral pharyngoplasty with stylopharyngeal muscle preservation

Tratamento da apneia obstrutiva do sono por meio da faringoplastia lateral consiste na miotomia e reposicionamento dos músculos da parede lateral da faringe. A disfagia após cirurgia faríngea é influenciada pela dor, pelo incômodo das suturas, pela cicatrização e pela adaptação às alterações estruturais da faringe. A experiência com a faringoplastia mostra que o músculo constritor superior da faringe exerce um papel de pouca importância na deglutição, sua miotomia é totalmente compensada pela ação dos demais músculos da orofaringe. O estilofaríngeo exerce importante papel na deglutição. OBJETIVO: Avaliar, diariamente, evolução da deglutição nos pacientes submetidos à faringoplastia lateral com identificação e preservação do músculo estilofaríngeo. MÉTODO: O estudo é prospectivo e avaliamos a deglutição de 20 pacientes, por meio da aplicação diária de uma escala analógica visual desde o primeiro pós-operatório até a normalização da deglutição. RESULTADOS: Os pacientes retornaram a sua dieta livre habitual, em média, 10,9 dias após as cirurgias e referiram apresentar deglutição normal, em média, com 21,6 dias. Todos os casos referiram retornar à deglutição normal no pós-operatório, com um prazo de recuperação de 33 dias. CONCLUSÃO: Todos os pacientes submetidos à faringoplastia com preservação do músculo estilofaríngeo referiram normalização da deglutição em até 33 dias após a cirurgia.

Lateral pharyngoplasty manages obstructive sleep apnea through the myotomy and repositioning of the muscles of the lateral pharyngeal wall. Dysphagia after any pharyngeal surgery is influenced by pain, discomfort from the sutures, the healing process and by the adaptation to the changes in pharyngeal structures. Experience with lateral pharyngoplasty has shown that the superior pharyngeal constrictor muscle plays a minor role in swallowing. One of them, the stylopharyngeus muscle, seems to play an important role during swallowing. OBJECTIVE: The aim of this study is to provide a daily analysis of the follow-up of the swallowing function. METHOD: We have prospectively evaluated the swallowing function in 20 patients, through the daily application of a visual analogue scale from the first post-op until the complete disappearance of dysphagia. RESULTS: Patients have returned to their normal feeding habits in a mean of 10.9 days after the procedures and they presented a completely normal swallowing, on average, 21.6 days after the surgeries. All patients recover normal swallowing after the procedures, with a maximum recovery time of 33 days. CONCLUSION: In this study, all patients who underwent lateral pharyngoplasty with total preservation of the stylopharyngeus muscle reported complete normalization of swallowing with a recovery time up to 33 days.

Estudo comparativo entre pacientes fissurados portadores de insuficiência velofaríngea tratados com fonoterapia e faringoplastia / Comparative study among cleft patients with velopharyngeal insufficiency treated with speech therapy and pharyngoplasty

INTRODUÇÃO: A inadequação da fala e da voz decorrente da insuficiência velofaríngea é o principal estigma do paciente fissurado; assim, o estudo dessa condição clínica é fundamental, proporcionando melhor desenvolvimento das crianças e de suas relações sociais. O objetivo do presente estudo é avaliar alterações fonoaudiológicas, do esfíncter velofaríngeo, da laringe de pacientes fissurados palatais e labiopalatais tratados com queiloplastia, palatoplastia e fonoterapia, que desenvolveram insuficiência velofaríngea transitória, e fissurados palatais e labiopalatais, que desenvolveram insuficiência velofaríngea persistente tratados com queiloplastia, palatoplastia, fonoterapia, faringoplastia e fonoterapia complementar. MÉTODO: No período de junho de 1997 a maio de 2002, foram avaliados 132 fissurados palatais e labiopalatais que desenvolveram insuficiência velofaríngea transitória e insuficiência velofaríngea persistente, com idade entre 4 anos e 11 meses e 19 anos e 3 meses. Observando-se os critérios de inclusão e exclusão, 44 pacientes, sendo 18 do gênero feminino e 26 do gênero masculino, foram divididos em 2 grupos: grupo I, 20 pacientes submetidos a queiloplastia, palatoplastia e fonoterapia; e grupo II, 24 pacientes submetidos a queiloplastia, palatoplastia, fonoterapia, faringoplastia e fonoterapia complementar. O tratamento fonoaudiológico consistiu de terapia articulatória de fluxo aéreo bucal, terapia miofuncional, técnica de aquisição fonêmica rápida e terapia de voz. O tratamento cirúrgico consistiu de confecção de retalho da parede posterior da faringe, de pedículo superior. RESULTADOS: As alterações fonoaudiológicas, do esfíncter velofaríngeo e da laringe foram mais frequentes nos pacientes do grupo I, quando comparados aos do grupo II. CONCLUSÕES: Pacientes fissurados que evoluíram para insuficiência velofaríngea persistente devem ser tratados com faringoplastia e fonoterapia complementar para correção das alterações fonoaudiológicas, do esfíncter velofaríngeo e da laringe.

BACKGROUND: Inadequacy of speech and voice due to velopharyngeal insufficiency is a major stigma for cleft patients. Therefore, the study of this clinical condition is essential to improve the development and social relations of children with this ailment. This study aimed to assess alterations in the speech, velopharyngeal sphincter, and larynx of patients with cleft palate and cleft lip and palate who underwent to lip closure, palatoplasty, and speech therapy and developed transitory velopharyngeal insufficiency. Furthermore, these patients were compared with cleft palate and cleft lip and palate patients who developed persistent velopharyngeal insufficiency treated with lip closure, palatoplasty, speech therapy, pharyngoplasty, and complementary speech therapy. METHODS: From June 1997 to May 2002, 132 cleft palate and cleft lip and palate patients aged between 4 years 11 months and 19 years 3 months with transitory velopharyngeal insufficiency and persistent velopharyngeal insufficiency were assessed. After applying inclusion and exclusion criteria, 44 patients, 18 females and 26 males, were divided into 2 groups: group I, 20 patients who underwent lip closure, palatoplasty and speech therapy; and group II, 24 patients who underwent lip closure, palatoplasty, speech therapy, pharyngoplasty, and complementary speech therapy. Speech therapy consisted of articulatory therapy of oral airflow, myofunctional therapy, rapid phonemic acquisition technique, and voice therapy. Surgical treatment consisted of producing a flap from the pharynx posterior wall of the upper pedicle. RESULTS: Alterations in speech, the velopharyngeal sphincter, and the larynx were more frequent in group I than in group II. CONCLUSIONS: Cleft patients with persistent velopharyngeal insufficiency should be treated with pharyngoplasty and complementary speech therapy in order to correct alterations in speech, the velopharyngeal sphincter, and the larynx.

A survey of facial nerve dessection techniques in benign parotid surgery among maxillofacial and ear, nose, and throat surgeons in Nigeria

Objective: The aim of the present study is to identify the facial nerve dissection technique routinely used during parotidectomy for benign parotid tumors by Nigerian Oral and Maxillofacial (OMF) and Ear; Nose; and Throat (ENT) Surgeons. Materials and Methods: A questionnaire-based study was conducted among Oral and Maxillofacial and Ear; Nose; and Throat Surgeons in Nigeria; on their experience with antegrade and retrograde facial nerve dissection techniques in parotid surgery. The respondents were asked to indicate their choice of dissection techniques in revision parotidectomy; limited superficial parotidectomy; and in obese patients with large tumors. They were also asked to indicate if they routinely used perioperative facial nerve monitoring devices in parotid surgery for benign tumors. Result: About half (47.5) of them routinely used the antegrade technique; while only a few (12.5) used the retrograde technique. A large number of them (40); however; used a combination of antegrade and retrograde routinely. Technical ease was the main reason for the choice of technique. The antegrade technique was the technique of choice by most respondents for revision parotidectomy (60) and limited superficial parotidectomy (62). However; the retrograde approach was the technique of choice by most of them (47) in case of parotidectomy in obese patients with large tumors. The routine use of perioperative facial nerve monitoring devices is an uncommon practice among OMF and ENT surgeons in Nigeria. Conclusions: The antegrade approach for facial nerve dissection is the most common technique used in parotid surgery by Nigerian OMF and ENT surgeons. Nigerian surgeons need to consider the retrograde approach in selected cases of parotid surgery especially for localized tumors that are amenable to limited superficial parotidectomy. Inclusion of perioperative facial nerve monitoring devices is also advocated

Surgical treatment of snoring & obstructive sleep apnoea.

Obstructive sleep apnoea (OSA) syndrome is a potentially serious disorder affecting millions of people around the world. Many of these individuals are undiagnosed while those who are diagnosed, often exhibit poor compliance with nightly use of continuous positive airway pressure (CPAP), a very effective nonsurgical treatment. Various surgical procedures have been proposed to manage and, in some cases, treat OSA. In this article we review methods used to assess the sites of obstruction and a number of surgical procedures designed to address OSA. Effective surgical management of OSA depends upon developing a complete database and determining different levels of obstruction, which may include nasal, nasopharyngeal, oropharyngeal, and hypopharyngeal/retrolingual, or a combination of these sites. A systematic approach to clinical evaluation, treatment planning and surgical management is recommended and is likely to result in more predictable outcomes. Surgical treatment may involve various procedures that are performed in different stages depending on the patient’s sites of obstruction. The most commonly performed procedures include nasal reconstruction, uvulopalatopharyngoplasty (UPPP), advancement genioplasty, mandibular osteotomy with genioglossus advancement, and hyoid myotomy and suspension. In more severe cases, maxillomandibular advancement (MMA) with advancement genioplasty may be indicated. Even after appropriate surgical treatment, some patients may demonstrate continued obstruction with associated symptoms. Published indications for surgical treatment include an elevated respiratory disturbance index (RDI) with excessive daytime somnolence (EDS), oxygen desaturations below 90 per cent, medical co-morbidities including hypertension and arrhythmias, anatomic abnormalities of the upper airway and failure of medical treatment. The success of surgery in OSA is generally measured by achieving a (RDI) of less than 5, improvement of oxygen nadir to 90 per cent or more with no desaturations below 90 per cent and quality of life improvements with elimination or significant reduction of OSA symptoms. From a practical point of view, achieving these goals may be extremely difficult without patients’ cooperation, most notably in the realm of weight loss and maintenance of a healthy lifestyle.

Effect of classic uvulopalatopharyngoplasty and laser-assisted uvulopalatopharyngoplasty on voice acoustics and speech nasalance

Uvulopalatopharyngoplasty [UPPP] is a commonly used surgical technique for oropharyngeal reconstruction in patients with obstructive sleep apnea [OSA]. This procedure can be done either through the classic or the laser-assisted uvulopalatopharyngoplasty [LAUP] technique. The purpose of this study was to evaluate the effect of classic UPPP and LAUP on acoustics of voice and speech nasalance, and to compare the effect of each operation on these two domains. The study included 27 patients with a mean age of 46 years. All patients were diagnosed with OSA based on polysomnographic examination. Patients were divided into two groups according to the type of surgical procedure. Fifteen patients underwent classic UPPP, whereas 12 patients were subjected to LAUP. A full assessment was done for all patients preoperatively and postoperatively, including auditory perceptual assessment [APA] of voice and speech, objective assessment using acoustic voice analysis and nasometry. Auditory perceptual assessment of speech and voice, acoustic analysis of voice and nasometric analysis of speech did not show statistically significant differences between the preoperative and postoperative evaluations in either group [P>.05]. The results of this study demonstrated that in patients with OSA, the surgical technique, whether classic UPPP or LAUP, does not have significant effects on the patients' voice quality or their speech outcomes

Use of Muller's maneuver in the evaluation of patients with sleep apnea: literature review / Utilização da manobra de Müller na avaliação de pacientes apnéicos: revisão da literatura

Sleep apnea-hypopnea syndrome was described twenty years ago, and since then there have been doubts and controversies regarding it. Fiberoptic nasopharyngoscopy with Muller's maneuver, first described by Borowieck and Sassin (1983), is among them. AIM: Careful literature review on Muller's maneuver, regarding whether it can predict the sucess of uvulopalatopharyngoplasty, location of upper airway obstruction and severity of the disorder. DISCUSSION AND LITERATURE REWIEW: Literature has shown that there isn't a consensus about the use of Muller's maneuver. In spite of being technically easy, inexpensive and widely used, it is very unespecific and subjective. CONCLUSION: The importance of Muller's maneuver in evaluating apneic patients has been questioned, because there are controversies whether it can predict the sucess of uvulopalatopharyngoplasty, location of upper airway obstruction and severity of the disease.

A Síndrome da Apnéia e Hipopnéia Obstrutiva do Sono é uma patologia descrita há apenas vinte anos, havendo ainda várias dúvidas e controvérsias a seu respeito. Nesse âmbito inclui-se a nasofibrolaringoscopia com Manobra de Müller descrita por Borowieck e Sassin em 1983 e motivo de análise neste artigo. OBJETIVO: Revisão da literatura, com análise crítica e comparativa a respeito da capacidade da nasofibrolaringoscopia com manobra de Müller de predizer o sucesso da uvulopalatofaringoplastia, o local de colapso da via aérea superior e a gravidade da doença. DISCUSSÃO E REVISÃO DA LITERATURA: A revisão da literatura mostra que não há um consenso sobre a utilização da manobra de Müller, pois apesar de ser um exame de fácil execução, custo e tempo efetivos, é também bastante inespecífico e subjetivo. CONCLUSÃO: A relevância da manobra de Müller na avaliação do paciente apnéico tem sido questionada, pois há controvérsias na literatura quanto a sua capacidade de predizer o sucesso da cirurgia orofaríngea, o local de colapso da via aérea superior e a gravidade da apnéia.

Carótida interna retrofaríngea: relato de caso / Retropharyngeal internal carotid artery: case report

Introdução: Anomalias no trajeto das artérias carótidas podem gerar protrusões faríngeas, para as quais o otorrinolaringologista deve estar sempre atento. Objetivo: Descrever um caso de abaulamento orofaríngeo causado por anomalia vascular no trajeto da carótida interna, com revisão da literatura. Relato do Caso: Paciente de 73 anos, sexo feminino, apresentou-se com queixas de bolo cervical e disfonia intermitente. Ao exame, foi evidenciado abaulamento pulsátil em orofaringe à direita, associado aos sinais laringoscópicos de refluxo faringo-laríngeo. Solicitada tomografia computadorizada de faringe, que mostrou carótida interna tortuosa em espaço retrofaríngeo. A paciente foi encaminhada ao cirurgião vascular que, após Doppler de carótidas, que não revelou obstrução significativa, optou por conduta expectante. Os sintomas faríngeos cederam com o tratamento anti-refluxo. Comentários Finais: Anomalias vasculares da carótida interna devem ser sempre lembradas no diagnóstico diferencial de abaulamentos da parede faríngea.

Introduction: Variations to the course of carotid arteries may lead to abnormal pharyngeal protrusions, to which the otorhinolaryngologist should always attentive. Objective: To report a case of abnormal pharyngeal protrusion due to vascular anomaly in the course of the internal carotid artery, with literature review. Case Report: A 73- year-old woman complained of globus pharyngeus and intermittent dysphonia. A pulsating convexity was observed at the right part of the oropharynx, associated to laryngoscopic signals of pharyngo-laryngeal reflux. The pharyngeal computed tomography scan showed an abnormal tortuous internal carotid in the retropharyngeal space. The patient was sent to the vascular surgeon, who, after a normal blood flow finding at the Doppler, opted for an expectation conduct. The pharyngeal symptoms improved with the antireflux treatment. Final Comments: Internal carotid vascular anomalies must always be recalled in the pharyngeal wall convexity differential diagnosis.

Reabilitação fonatória do laringectomizado total: utilização de toxina botulínica na voz tráqueo-esofágica com prótese fonatória / Botulinum toxin in speech rehabilitation with voice prosthesis after total laryngectomy

Na punção tráqueo-esofágica(PTE) é realizada miotomia do músculo constritor da faringe, mas sua necessidade é entre 9 por cento a 79 por cento dos pacientes. Sua realização pode aumentar as taxas de fístula salivar no pós-operatório. A aplicação da TB é ambulatorial. OBJETIVO: Análise da eficácia da aplicação de toxina botulínica (TB), na reabilitação do laringectomizado total com voz tráqueo-esofágica(VTE) com espasmo(E) do segmento faringo-esofágico (SFE) sem miotomia. MATERIAL E MÉTODOS: Análise de oito pacientes submetidos à laringectomia total (LT), reabilitados com VTE com prótese fonatória (PF), esforço para emissão de voz devido à E do SFE. Todos submetidos a tratamento dessa alteração motora com injeção de 100 unidades de TB no SFE. A avaliação constituiu-se de análise perceptiva de voz, videofluoroscopia (VF) do SFE, análise acústica de voz e manometria computadorizada (MC) do SFE, todos antes e após aplicação de TB. DESENHO DE ESTUDO: Estudo prospectivo. RESULTADOS: Houve diminuição na pressão à MC do SFE, após a injeção de TB. Análise acústica demonstrou melhora na qualidade de harmônicos após o tratamento. Houve emissão de voz sem esforço e melhora do E após o uso da TB. CONCLUSÃO: Todos os pacientes com E do SFE apresentaram melhora vocal após aplicação da TB neste SFE.

In tracheo esophageal puncture (TEP), we carry out a myotomy of the pharynx constrictor muscle; however, about 9 to 79 percent of patients need such procedure. The consequence of such procedure is an increase in salivary fistula rates in the postoperative. Botulin toxin is used in an outpatient basis. AIM: analyzing the efficacy of botulin toxin (BT) use in the rehabilitation of totally laryngectomized patients with tracheo-esophageal voice (TEV) with spasms (S) of the pharyngo-esophageal segment (PES) without myotomy. MATERIALS AND METHODS: We analyzed eight patients submitted to total laryngectomy (TL), rehabilitated with TEV, with speech prosthesis (SP) and struggle to utter voice because of PES spasms. They were all submitted to treatment of such motor alteration with the injection of 100 units of BT in the PES. The evaluation was based on perceptive voice analysis, video fluoroscopy (VF) of the PES, acoustic voice analysis and computerized manometry (CM) of the PES, all before and after BT injection. STUDY DESIGN: prospective. Results: There was a reduction in PES CM pressure after BT injection. Acoustic analysis showed an improvement in harmonics quality after treatment. There was smoother voice utterance and spasm improvement after BT. CONCLUSION: all patients with PES spasms presented vocal improvement after BT injection in the PES.

Estudo comparativo entre cetorolaco e cetoprofeno no controle da dor pós-operatória de uvulopalatofaringoplastia / A comparative study between Ketorolac and Ketoprofen in postoperative pain after uvulopalatopharyngoplasty

A dor no pós-operatório imediato apresenta-se como um grave problema, requerendo do médico uma adequada assistência. Na Otorrinolaringologia, merece atenção especial a dor após uvulopalatofaringoplastia (UPFP). OBJETIVO: Comparar a eficácia na analgesia pós-operatória do cetorolaco com o cetoprofeno em UPFP. PACIENTES E MÉTODOS: Estudo prospectivo, randomizado, duplo-cego com 24 pacientes submetidos à UPFP, divididos em 2 grupos, sendo que 14 receberam cetorolaco e 10 cetoprofeno. Avaliação da intensidade da dor através de escala visual analógica e necessidade do uso associado de opióide (tramadol). RESULTADOS: Dos 14 pacientes que receberam cetorolaco, apenas 3 (21 por cento) necessitaram uso complementar de opióide, enquanto que 7 (70 por cento) do grupo do cetoprofeno o fizeram. Após 12 horas de cirurgia, houve um predomínio de 71 por cento dos pacientes que receberam cetorolaco, com dor leve ou até ausência desta, enquanto 70 por cento dos do cetoprofeno referiram dor moderada ou incômoda. Após 24 horas de cirurgia, 60 por cento dos pacientes que fizeram uso de cetoprofeno referiam dor moderada a incômoda, ao passo que 86 por cento dos do cetorolaco referiram dor leve à ausência. CONCLUSÃO: Conclui-se que o cetorolaco é mais eficaz em relação ao cetoprofeno no tratamento da dor pós-operatória imediata de UPFP, pois houve dor de menor intensidade e menor uso de opióide.

Postoperative pain is a serious problem, requiring an appropriate response from the medical doctor. In otolaryngology special attention is needed after uvulopalatopharyngoplasty (UP3). AIM: To compare the efficacy of postoperative analgesia using ketorolac and ketoprofen after UP3. PATIENTS AND METHODS: A prospective, randomized, double-blind study was made of 24 patients that were divided into 2 groups (14 received ketorolac and 10 received ketoprofen). Pain intensity was based on an analog visual scale and the need for opioids (tramadol). RESULTS: Of the 13 patients that received ketorolac, 3 (21 percent) required opioids; 7 of 10 (70 percent) patients in ketoprofen group used opioids. 12 hours after surgery, 71 percent of the patients that received ketorolac had mild or absence of pain. 70 percent of the ketoprofen users reported moderate to significant pain. 24 hours after surgery, 60 percent of the patients using ketoprofen reported moderate to significant pain, while 86 percent of the ketorolac users reported mild or absence of pain. CONCLUSION: We concluded that ketorolac is more effective compared to ketoprofen in the treatment of immediate postoperative pain after UP3, as patients using ketorolac had less pain and used opioids to a lesser degree.

role of pharyngeal repair on acoustic characteristics of tracheoesophageal voice

The tracheoesophageal puncture [TEP] technique for voice restoration is a successful way of providing voice rehabilitation after total laryngectomy. Because postoperative voice quality can vary significantly depending on which type of hypopharyngeal repair is chosen, the aim of this work was to evaluate the effect of these repairs on the TEP voice after total laryngectomy. In this study, the TEP voice was quantitatively and qualitatively evaluated in 20 patients using Provox 2 A registerd prosthesIs after standard total laryngectomy. The patients were divided according to the type hypopharyngeal repair into four groups [five cases for each]; A: pharyngoesophageal myotomy, B: pharyngeal plexus neurectomy, C: non-muscle repair, and D: transverse repair. The groups were compared with each other for different voice parameters. The acoustic results of the four pharyngeal repair groups did not reveal significant difference for most of the voice parameters. Primary TEP voice restoration is recommended as it offers several advantages; 1. I simple, effective and not time consuming, 2. It is a low morbidity procedure, 3. It is cost effective as it eliminates a secondary procedure for voice restoration and reduces prolonged speech therapy sessions, 4. Early voice production gives the patient a psychological boost which improves convalescence. All used methods of pharyngeal repair succeeded to prevent postoperative neopharyngeal spasm
