Ligadura de la arteria lingual: estrategia para hemorragias por lesión de la arteria en la base de la lengua: informe de dos casos / Lingual Artery Ligation: Strategy for Bleeding from Artery Injury at the Base of the Tongue: Report of Two Cases

La hemorragia producida por lesión de la arteria lingual en la base de la lengua por cirugías o por tumores es infrecuente. La mayor frecuencia en la indicación de abordajes transorales para tratar diferentes patologías que afectan la orofaringe requiere que el equipo quirúrgico tenga experiencia en el manejo de esta complicación. La ligadura de la arteria lingual en el cuello es una técnica quirúrgica muy eficaz para solucionar la hemorragia, pero es importante conocer las posibles variantes anatómicas que puede tener la arteria en su trayecto cervical. Debido a su baja incidencia se propone como objetivo describir dos casos clínicos de pacientes que tuvieron hemorragias graves por lesión de la arteria lingual en la base de la lengua, producidas por daño quirúrgico y por erosión por tumor. [AU]

The bleeding caused by injury to the lingual artery at the base of the tongue due to surgery or tumors is infrequent. The increased frequency in the indication of transoral approaches to treat different pathologies affecting the oropharynx requires the surgical team to have experience in managing this complication. Ligation of the lingual artery in the neck is a very effective surgical technique to solve the bleeding; however, it is essential to be aware of the possible anatomical variants the artery may have in its cervical trajectory. Due to its low incidence, we propose to describe two clinical cases of patients who had severe bleeding due to a lesion of the lingual artery at the base of the tongue, produced by surgical damage and erosion due to a tumor.

Importance of the use of pre- and intra-operative imaging as a tool for planning foreign body removal in the floor of the mouth: a case report / Importancia del uso de la imagenología pre e intraoperatoria como herramienta para la planificación de remoción de cuerpo extraño en piso de boca: presentación de un caso

Introduction: Body piercings consist of small holes made with a needle in different parts of the skin or body to introduce a jewel or decorative element. In the oral cavity, most piercings are placed in the tongue. However, some complications may occur, and surgical techniques must be used for their removal. These complications present a certain degree of difficulty due to their position and may challenge the ability of the clinician to access the specific anatomical location. The different imaging techniques, from simple radiography to intraoperative techniques such as image intensifiers, have become an extremely useful tool for locating an object in the three dimensions of space, allowing safe location and extraction. Objective: The aim of this study is to report the case of a complication of a body piercing in the oral cavity and how the use of imaging was decisive for surgical planning and for the quick and effective resolution of the case. Material and Methods: A 14-year-old female patient came looking for treatment. Her mother reported the onset of the condition after the insertion of a needle-like metallic object while performing an artistic perforation in the lingual region. Since the girl was unable to extract the object, she sought medical advice at the Carlos Arvelo Military Hospital in Caracas, Venezuela. Subsequently, an imaging study was performed by means of a Computed Tomography to locate the metallic object. It was observed that the foreign body had migrated to the floor of the mouth/sublingual region, requiring the area to be surgically approached. It was also decided to use an intraoperative image intensifier. The removal of the object was performed satisfactorily. Conclusion: The extraction of foreign bodies placed in the lingual and sublingual region represents a challenge for the clinician due to the number of important anatomical structures that pass through that area. This makes clinicians plan their surgical removal using pre- and intraoperative imaging, to find a less traumatic location, reduce surgical time as well as the risk of damaging adjacent anatomical structures.

Introducción: Los body piercings consisten en producir perforaciones con una aguja en diferentes localizaciones de la piel con el fin de introducir una joya o elemento decorativo a través del agujero producido previamente. En la cavidad oral, la lengua es el sitio de mayor elección; sin embargo, en ciertas ocasiones suelen presentarse ciertas complicaciones, por lo cual se debe recurrir a técnicas quirúrgicas para su remoción presentando cierto grado de dificultad para su localización y la capacidad del clínico para acceder al espacio anatómico. Las diferentes técnicas imagenológicas desde una radiografía simple hasta técnicas intraoperatorias como los intensificadores de imágenes se han convertido en una herramienta sumamente útil para la ubicación de un objeto en las tres dimensiones del espacio, permitiendo una localización y extracción segura para el clínico y el paciente. Objetivo: El propósito de este trabajo es reportar un caso de una complicación de esta práctica en la región bucal y cómo el uso de la imagenología fue determinante para la planificación quirúrgica y la resolución del caso de manera rápida y efectiva. Material y Métodos: Se presenta a consulta una paciente femenina de 14 años de edad, quien madre refiere inicio de enfermedad actual posterior a introducirse objeto metálico tipo aguja de compás con la finalidad de realizar perforación artística en región lingual, al no poder extraer dicho objeto, acude a evaluación en el Hospital Militar Carlos arvelo de Caracas; posterior se realiza estudio imagenológico tipo Tomografía Computarizada para la ubicación del objeto metálico donde se observa que el cuerpo extraño habría migrado hacia el piso de boca/región sublingual, teniendo la necesidad de abordar quirúrgicamente la zona y elegir el uso de intensificador de imagen transoperatorio para retiro del mismo el cual se dio de manera satisfactoria. Conclusión: Los cuerpos extraños desplazados a la región lingual y sublingual representan un desafío para el clínico al momento de extraerlos, esto se debe a la cantidad de estructuras anatómicas importantes que pasan por dicha zona, lo que hace que el clínico opte en su planificación quirúrgica por el uso de imagenología pre y transoperatoria obteniendo así una localización menos traumática, menor tiempo operatorio y menor riesgo de lesión de estructuras anatómicas adyacentes.

Transoral robotic surgery for treatment of lingual thyroglossal duct cyst / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the feasibility, safety and efficacy of transoral robotic surgery (TORS) in the treatment of lingual thyroglossal duct cyst (LTGDC). Methods: The clinical data of 10 patients with LTGDC treated with TORS in Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology from May 2017 to November 2020 were analyzed retrospectively,including 6 males and 4 females, aged 5-44 years. The cysts were fully exposed, and resection usually started from the cephalic side of lesions. The range of resection was 3 to 5 mm away from the lesions, and partial hyoid bone was removed if necessary. Intra-operative robotic set-up time,operation time and estimated blood loss,and post-operative local bleeding, dyspnea and recovery time for oral intake were analyzed. SPSS 12.0 software was used for statistical analysis. Results: The cysts in all 10 patients were successfully resected by TORS with da Vinci Si surgical system. The mean robotic set-up and exposure time, operation time, estimated intraoperative blood loss and recovery time for oral intake were (15.5±7.1) min, (17.6±7.4) min, (8.9±6.4)ml and (2.3±2.2)days, respectively. No patient required tracheostomy intra-or post-operatively, and no symptoms of airway obstruction, postoperative bleeding, pharyngeal fistula, hoarseness and neurological impairment occurred after operation. The patients were followed up for 5 to 47 months, with median follow-up time of 17 months, and no recurrence was observed. Conclusion: TORS is safe and feasible for resection of LTGDC, with rapid recovery and low recurrence rate.

Efficacy of Han-uvulopalatopharyngoplasty (HUPPP) combined with radiofrequency ablation of tongue base or HUPPP with traction of tongue base on moderate to severe patients with obstructive sleep apnea hypopnea syndrome (OSAHS):a multicenter randomized controlled trial / 中华耳鼻咽喉头颈外科杂志

Objective: To compare the therapeutic efficacy of Han-uvulopalatopharyngoplasty (HUPPP) combined with radiofrequency ablation of tongue base or HUPPP with traction of tongue base on moderate to severe patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: This is a multicenter randomized controlled trial. From March 2017 to July 2019, moderate to severe OSAHS patients from three clinical center in Shanghai who were intolerant to continuous positive airway pressure (CPAP) and with velopharyngeal and glossopharyngeal plane obstruction were enrolled in this study. According to the surgical type, they were 1∶1 randomized to HUPPP plus radiofrequency ablation of tongue base group (Ablation group) or HUPPP plus traction of tongue base group (Traction group). All patients completed over-night standard Polysomnography (PSG), upper-airway assessment (Friedman classification, Müller test, CT and cephalometric examination), preoperative routine examination, Epworth Sleepiness Scale (ESS) and Quebec sleep questionnaire (QSQ). Six to 12 months after operation, all the above-mentioned examinations were repeatedly performed. Changes of aforementioned variables before and after operation were assessed. Results: A total of 43 patients with moderate to severe OSAHS were enrolled in this study. One patient lost to follow-up, the remaining 21 were allocated to Ablation group and 21 were allocated to Traction group. The total therapeutic efficacy of all patients was 69.05% (61.90% in Ablation group and 76.19% in Traction group), but there was no statistical significance between the two groups (P= 0.317). The value of sleep scale score (ESS and QSQ), objective sleep variables (apnea-hypopnea index, oxygen saturation, percentage of time with blood oxygen less than 90% in total sleep time, oxygen desaturation index and micro-arousals) and upper airway cross-sectional area (palatopharyngeal and retrolingual area) of the two groups were improved (P<0.05), but the differences between the two groups were not statistically significant (P>0.05). Conclusion: For moderate to severe OSAHS who had glossopharyngeal plane obstruction, both HUPPP plus radiofrequency ablation of tongue base or HUPPP plus traction of tongue base are effective treatment for OSAHS, and the curative effect is similar. The choice of surgical type could be selected according to patient's or surgical conditions.

Lingual Focal Hyperplastic Lesion in a Pediatric Patient: Report of an Unusual Case / Lesión hiperplásica focal lingual en un paciente pediátrico: Informe de un caso inusual

Abstract: Focal fibrous hyperplasia (FFH) is an oral mucosal localized non-neoplastic enlargement representing a reaction to chronic local irritations or injuries. The purpose of this report is to describe the management of an asymptomatic fibrotic lesion located in the tongue, in a preschooler boy. A 7-year-6-month old boy attended our clinic for the evaluation of an exophytic pedunculated tumor-like round mass located in the dorsal surface of the tongue. Based on the initial examination and the natural history of the lesion, the presumptive clinical diagnosis determined an irritation FFH. The lesion was surgically excised with a diode laser device, and the postoperative period evolution occurred without any complication. The appropriate treatment of FFH in children initially consists of the removal of local irritant factors. Excellent oral hygiene maintenance and close follow-up care are strongly suggested. Surgical excision is the most frequent modality for persistent lesions. Early diagnosis and proper management of FFH can reduce the risk of future recurrences or complications.

Resumen: La hiperplasia fibrosa focal (HFF) es un agrandamiento no neoplásico localizado en la mucosa oral que representa una reacción a irritaciones o lesiones locales crónicas. El propósito de este informe es describir el tratamiento de una lesión fibrótica asintomática ubicada en la lengua, en un niño en edad preescolar. Un niño de 7 años y 6 meses de edad asistió a nuestra clínica para la evaluación de una masa redonda exofítica y pedunculada con forma de tumor ubicada en la superficie dorsal de la lengua. Basado en el examen inicial y la historia natural de la lesión, el diagnóstico clínico presuntivo determinó una irritación HFF. La lesión se extirpó quirúrgicamente con un láser de diodo, y la evolución en el período postoperatorio se produjo sin ninguna complicación. El tratamiento apropiado de HFF en niños inicialmente consiste en la eliminación de factores irritantes locales. Se recomienda un excelente mantenimiento de la higiene bucal y una estrecha atención de seguimiento. La escisión quirúrgica es la modalidad más frecuente para lesiones persistentes. El diagnóstico temprano y el manejo adecuado de la HFF pueden reducir el riesgo de futuras recurrencias o complicaciones.

Outcomes of Tongue Base Reduction and Lingual Tonsillectomy for Residual Pediatric Obstructive Sleep Apnea after Adenotonsillectomy

Introduction: Upper airway obstruction at multiple sites, including the velum, the oropharynx, the tongue base, the lingual tonsils, or the supraglottis, has been resulting in residual obstructive sleep apnea (OSA) after tonsillectomy and adenoidectomy (TA). The role of combined lingual tonsillectomy and tongue base volume reduction for treatment of OSA has not been studied in nonsyndromic children with residual OSA after TA. Objective: To evaluate the outcomes of tongue base volume reduction and lingual tonsillectomy in children with residual OSA after TA. Methods: A retrospective chart review was conducted to obtain information on history and physical examination, past medical history, findings of drug-induced sleep endoscopy (DISE), of polysomnography (PSG), and surgical management. Pre- and postoperative PSGs were evaluated to assess the resolution of OSA and to determine the improvement in the obstructive apnea-hypopnea index (oAHI) before and after the surgery. Results: A total of 10 children (5 male, 5 female, age range: 10­17 years old, mean age: 14.5 ± 2.6 years old) underwent tongue base reduction and lingual tonsillectomy. Drug-induced sleep endoscopy (DISE) revealed airway obstruction due to posterior displacement of the tongue and to the hypertrophy of the lingual tonsils. All of the patients reported subjective improvement in the OSA symptoms. All of the patients had improvement in the oAHI. The postoperative oAHI was lower than the preoperative oAHI ( p < 0.002). The postoperative apnea-hypopnea index during rapid eye movement sleep (REM-AHI) was lower than the preoperative REM-AHI ( p = 0.004). Obstructive sleep apnea was resolved in children with normal weight. Overweight and obese children had residual OSA. Nonsyndromic children had resolution of OSA or mild OSA after the surgery. Conclusions: Tongue base reduction and lingual tonsillectomy resulted in subjective and objective improvement of OSA in children with airway obstruction due to posterior displacement of the tongue and to hypertrophy of the lingual tonsils (AU)

Modelo de dissecção e acesso vascular de baixo custo / Low cost model for vascular dissection and access

OBJETIVO: Descrever um modelo de treinamento de baixo custo de dissecção e acesso vascular utilizando língua bovina. MÉTODOS: Foram utilizadas dez línguas de boi para confecção de simuladores. Inicialmente, o corpo da língua foi dissecado, separando as camadas epitelial e muscular, e o pedículo vascular foi destacado da base da língua. A artéria principal da língua foi, então, cateterizada e conectada a uma seringa, sendo, em seguida, fixada à porção muscular. Após, para simular o tecido celular subcutâneo, foi confeccionada uma pasta amarela gelatinosa, que foi posicionada de modo a cobrir a extensão do pedículo vascular por inteiro. Por fim, a camada epitelial da língua foi reposicionada sob a camada muscular, por meio de sutura contínua. Para avaliar o modelo, foram observados o tempo de confecção do modelo, sua durabilidade, seu custo e o número de vezes que pôde ser usado. RESULTADOS: O tempo médio para confecção do modelo foi de 15,82±2,45 minutos, com durabilidade de 20 dias sob refrigeração. O custo médio foi de R$25,00, podendo ser utilizado, em média, por 3,8±0,63 vezes. Não houve falhas na montagem do modelo. CONCLUSÃO: O modelo de língua de boi se mostrou viável e de fácil aplicação para o treinamento de técnica cirúrgica de dissecção vascular. (AU)

OBJECTIVE: To describe a low cost training model for dissection and vascular access using a bovine tongue. METHODS: Ten bovine tongues were used to build simulators. First, the body of the tongue was dissected, with its epithelial layer being separated from the muscular layer, and the vascular pedicle was detached from the base of the tongue. The tongue main artery was then catheterized and connected to a syringe, and subsequently fixed to the muscle layer. Then, the entire vascular pedicle was covered with a yellow gelatinous paste to simulate the subcutaneous tissue. Finally, the epithelial layer was repositioned above the muscle layer through continuous suture. To evaluate the model, 4 variables were considered: 1) time for building the model, 2) its durability, 3) its cost, 4) number of times that it could be used. RESULTS: The mean time to make the model was 15.82 ±2.45 minutes, with a durability of 20 days under refrigeration. The mean cost of each model was U$10.00, and could be used about 3.8±0.63 times. There were no fails to build the model. CONCLUSIONS: The model with a bovine tongue proved to be viable and easy to be applied for training the surgical technique of vascular dissection. (AU)

Aspectos do sistema estomatognático pré e pós-adenotonsilectomia / Aspects of stomatognathic system before and after adenotonsillectomy

OBJETIVO: Verificar os aspectos fonoaudiológicos do sistema estomatognático, incluindo as estruturas fonoarticulatórias (lábios, língua e palato mole) e as funções de deglutição, respiração, fala e fonação (qualidade vocal e ressonância), pré e pós adenotonsilectomia. MÉTODOS: Participaram 22 crianças, 17 do gênero masculino e cinco do gênero feminino, na faixa etária entre 5 e 10 anos. Todas apresentavam hipertrofia de tonsilas palatina e faríngea com indicação cirúrgica de adenotonsilectomia e nenhuma delas havia passado por fonoterapia prévia. A avaliação fonoaudiológica foi realizada no período pré-operatório e entre um e seis meses após a adenotonsilectomia e constou de avaliação das estruturas (lábios, língua e palato mole), das funções de deglutição (líquido), respiração (modo), fala e fonação (qualidade vocal e ressonância). Para avaliar a qualidade vocal e a ressonância, participaram 15 sujeitos com avaliação pós-operatória realizada no período de um a dois meses. RESULTADOS: Houve diferença quanto ao modo respiratório nasal, postura de lábios ocluídos em repouso, tônus de língua alterado, mobilidade adequada de palato mole, postura de língua alterada na deglutição de líquido, e ausência do mecanismo compensatório de interposição de lábios na deglutição. Houve redução na frequência dos processos de distorção. Em relação à fonação, foi observada discreta melhora na qualidade vocal e ressonância. CONCLUSÃO: Após a adenotonsilectomia algumas estruturas e funções podem se readaptar ou apresentar melhora espontaneamente. No entanto, foi necessário encaminhar a maioria das crianças para o atendimento fonoaudiológico na busca da readaptação das estruturas estomatognáticas e funções avaliadas.

PURPOSE: To verify the speech therapy aspects of the stomatognathic system, including phonoarticulatory structures (lips, tongue, and soft palate) and swallowing, respiratory, speech, and phonation (vocal quality and resonance) functions, before and after undergoing adenotonsillectomy. METHODS: The study included 22 children, 17 males and 5 females, aged between 5 and 10 years, suffering from hypertrophy of palatine and adenoid tonsils, with surgical indication for adenotonsillectomy and with no previous speech therapy. The speech-language pathology evaluation was performed before surgery and during the period between 1 and 6 months after adenotonsillectomy. It consisted of an evaluation of structures (lips, tongue, and soft palate) and of swallowing (liquid), respiration (mode), speech, and phonation (voice quality and resonance) functions. To evaluate vocal quality and resonance, 15 participants with the postoperative evaluation carried out in a period from 1 to 2 months were considered. RESULTS: There were differences regarding nasal respiratory mode, lips closed at rest posture, changed tongue tonus, adequate mobility of the soft palate, changed tongue posture during liquid swallowing, and absence of interposition compensatory mechanism of lips in swallowing. Reduction in the frequency of distortion processes was also found. With regard to speech, little improvement in vocal quality and resonance was seen. CONCLUSION: Following adenotonsillectomy, some structures and functions can spontaneously readapt or improve. However, most children needed to be referred to speech therapy for readapting stomatognathic structures and the assessed functions.

Glossectomia subtotal pela técnica de ressecção lingual em orifício de fechadura modificada como tratamento de macroglossia verdadeira / Subtotal glossectomy by modified keyhole lingual resection technique for the treatment of true macroglossia

Neste artigo é apresentado o caso de macroglossia verdadeira em criança de 6 anos de idade, tratada cirurgicamente, com excisão elíptica na linha média da língua e ressecção ampla na ponta da língua em arco gótico. O resultado pós-operatório foi considerado satisfatório, tanto sob o aspecto de volume da língua, que passou a se manter totalmente dentro da boca, como sob o aspecto estético, mantendo a capacidade de gustação normal.

We describe a case of true macroglossia in a 6-year-old child that was surgically treated with a midline elliptical excision and anterior wedge resection along a Gothic-shaped arch. The postoperative result was considered satisfactory with regard to both the volume of the tongue, which now remains entirely within the mouth, and the aesthetic appearance; the ability to taste has been maintained.

Suspension of the tongue to the digastric tendon following resection of the anterior mandibular arch for oral cancer prevents postoperative tongue fall and avoids the need for tracheostomy.

Background: Resection of the anterior arch of the mandible leads to tongue fall and postoperative stridor because of the detachment of tongue musculature from the mandible. In this article, a simple method of tongue suspension is described which would prevent such complications and the need for tracheostomy. Settings and Design: This study was carried out on patients with oral cancer requiring resection of the anterior arch of the mandible as a part of the surgical resection at a tertiary centre. Materials and Methods: This study was performed on 32 patients with oral cancer requiring resection of the anterior arch of the mandible as a part of the surgical resection. Following an appropriate resection of the oral cancer (including the anterior mandibular arch) and neck dissection, a silk suture is used to loop the tongue musculature on either side to the intermediate tendon of the digastric muscle. Result: This technique of tongue suspension was used in 32 patients who required resection of the anterior mandibular arch for oral cancer. Prophylactic tracheostomy was not performed. One patient developed stridor at extubation and required temporary tracheostomy. All other patients could be successfully extubated within 12 h of surgery and none experienced postoperative stridor or sleep apnea. One other patient required temporary tracheostomy for pulmonary toilet as he developed aspiration pneumonitis related to nasogastric feed. Conclusion: This simple method of tongue suspension to the digastric tendon prevents postoperative tongue fall and obviates the need for tracheostomy in most instances.

Hyalinizing clear cell carcinoma of the base of tongue: A distinct and rare entity.

Hyalinizing clear cell carcinoma (HCCC) of tongue is a rare neoplasm originating from minor salivary glands. We present a case of HCCC involving the base of tongue, in a 73-year-old male, clinically diagnosed as fibroma. Laser excison of the mass was done. Histopathological examination showed an infiltrating lesion composed predominantly of clear clear. The differential diagnosis included other salivary gland lesions having a clear cell component and metastatic clear cell renal carcinoma. lmmunohistochemistry was useful in ruling out these lesions exhibiting clear cell component from clear cell carcinoma. imaging studies revealed no lesion in either kidney. Since, HCCC has a better prognosis and the adequate treatment is wide excision, it needs to be differentiated from other carcinomas with clear cells. No further therapy was given to the patient. One year after the surgery, the patient is symptom free without local recurrence and on regular follow up.

Inclusão de fragmento dentário em língua por ferimento com arma de fogo / Inclusion of dental fragment in tongue for fi rearm injury

O aumento do número de vítimas de fraturas faciais causadas por arma de fogo em função da ascendência da violência urbana tornou-se uma grande preocupação nos serviços de atendimento de urgência. A compreensão desse tipo de ferimento necessita de conhecimentos sobre a biofísica da balística com a fi nalidade de planejar adequadamente o tratamento. Diante dessas considerações, os pacientes vítimados por esse tipo de acidente apresentam necessidades específi cas de tratamento para uma favorável evolução do caso. Os princípios para o tratamento de pacientes com ferimento em face causado por arma de fogo se dividem em três fases: primária (urgência), intermediária (suporte clínico) e reconstrutiva. Este artigo apresenta tópicos de interesse sobre a conduta frente aos ferimentos por arma de fogo e descreve um caso clínico de inclusão de um fragmento dental no interior da língua, diagnosticado em um paciente sete meses após ter sido atingido por umprojétil no corpo mandibular.

The increasing in the number of facial fractures victims caused by shot guns due to urban violence became an important concern on urgency services. The understanding of this kind oflesion involves knowledge of ballistics biophysics in order to plan suitable treatment. In front of these considerations, patients injured by this kind of accident presents specifi c needs of treatment for a satisfactory case evolution. The principles for treatment of patients with facial wounds caused by shot gun are divided in three steps: primary (urgency), intermediate (clinical support) and reconstructive. This paper presents interesting topics about the management of gunshot wounds and describes a clinical case of inclusion of a dental fragment inside the tongue, diagnosed in a patient, seven months after he has been reached by a projectile on mandibular body.

Comparison between eletrosurgery and cold blade in tongues of rats: a preliminary experimental study / Estudo comparativo entre eletrocirurgia e bisturi frio em língua de ratos: estudo preliminar experimental

PURPOSE: To compare tissue cicatrization in the tongue of rats using electrosurgery and the cold blade. METHODS: Ten adult male Wistar rats were divided into two groups of 5 animals each, according to the time of sacrifice (3 and 7 days). Each animal had two incisions, one made with a cold blade and the other with an electric blade, both of which were approximately 0.5 mm in length. Following sacrifice of the animals, the tongues were submitted to a histological study in order to classify the presence of angiogenesis, fibroblastic proliferation, epithelial proliferation and inflammatory cells as good, moderate and weak. RESULTS: The wound made with electric blade presented a delay in the healing process and a greater inflammatory response as compared with the cold blade, despite the fact that there was no statistically significant difference (p<0.05). CONCLUSION: There were no significant statistical differences between electrosurgery and the cold blade in relation to angiogenesis, fibroblastic proliferation, epithelial proliferation or the presence of inflammatory cells at any time of evaluation.

OBJETIVO: Comparar a cicatrização tecidual com bisturi elétrico e frio em língua de ratos. MÉTODOS: A amostra foi de 10 ratos Wistar, divididos em dois grupos com 5 animais em cada, de acordo com o tempo de sacrifício (3 e 7 dias).Cada animal teve duas incisões transversais, com 0,5 mm de comprimento, no dorso da língua, sendo a mais anterior com a eletrocirurgia (experimento), e a mais posterior, com bisturi convencional (controle). Após o sacrifício dos animais, as línguas foram submetidas a análise histológica para classificação da presença de angiogeneses, proliferação fibroblástica e epitelial e células inflamatórias em boa, moderada e fraca. RESULTADOS: Os resultados indicaram que as feridas realizadas com bisturi elétricos apresentaram um retardo no processo cicatricial e uma maior resposta inflamatória quando comparadas com as feridas do bisturi frio, apesar de não ter havido diferença estatisticamente significante (p<0.05). CONCLUSÃO: Não houve diferença significante entre o bisturi elétrico e frio em relação a presença de angiogeneses, proliferação fibroblástica e epitelial e células inflamatórias para nenhum dos dois tempos de avaliação.

Enfermedad de von Recklinghausen o neurofibromatosis plexiforme en lengua: presentación de un caso clínico y revisión de la literatura / Von Recklinghausen disease or plexiform neurofibromatosis of the tongue: case report and review of the literature

La enfermedad de von Recklinghausen o neurofibromatosis tipo 1 es una enfermedad de origen hereditario autosómico dominante. Presenta lesiones cutáneas, malformaciones esqueléticas y algún grado de retraso mental. Es frecuente que afecte la región de cabeza y cuello. La presencia de neurofibromas, tumores de la vaina nerviosa de comportamiento benigno y crecimiento lento es altamente probable durante la evolución de la enfermedad. Los plexiformes son patognomónicos de la enfermedad. La importancia de su estudio reside en el compromiso estéticoy funcional y en el mayor riesgo de su transformación maligna. No hay tratamiento específico; en general éste es sintomático y centrado en la prevención o el tratamiento de las complicaciones. Se deben realizar seguimientos clínicos e intervenciones quirúrgicas cuando las lesiones comprometen la estética o la función. La confirmación diagnóstica es sólo posterior al examen histológico. Se presenta un paciente con neurofibroma plexiforme en lengua y la revisión de la literatura sobre el tema.

Tratamiento quirúrgico del ronquido y la apnea obstructiva del sueño / Snoring and sleep apnea syndrome: surgical treatment

La roncopatía y la apnea obstructiva del sueño son problemas muy comunes en la población general. Su causa es un colapso de la vía aérea superior en cualquiera de sus niveles, nasal, orofaringeo y/o hipofaringeo (base de lengua). La roncopatía es un problema fundamentalmente social. Por otro lado la apnea obstructiva del sueño constituye un problema de riesgo médico por la mayor tasa de accidentes de tráfico, accidentes cardiovasculares, etc. Si bien es cierto ambas entidades son de resolución médica mediante el uso de CPAP, se han descrito un sinnúmero de técnicas quirúrgicas desde 1981 con el fin de ayudar a aquellos pacientes que no desean o no toleran el uso de CPAP.

Snoring and Sleep Apnea Syndrom are common disorders among general population. Both entities are produced by collapse of the Upper airway usually at multiples levels, nose, oropharinx and /or hypopharinx (base of tongue). Whereas snoring is social problem, sleep apnea syndrome is a medical entity because of the higher rates of traffic accidents and cardiovascular diseases. The current mainstay for treating these disorders is the CPAP, however many surgical procedures have been described since 1981 in order to help a group of patients who cannot or will not accept CPAP as a permanent form of management.

Mentoplastia para avanço do músculo genioglosso em pacientes com síndrome da apnéia-hipopnéia do sono obstrutiva e retrognatismo mandibular / Genioplasty for genioglossus muscle advancement in patients with obstructive sleep apnea-hypopnea syndrome and mandibular retrognathia

A Síndrome da Apnéia-Hipopnéia do Sono Obstrutiva (SAHSO) é um doença de fisiopatologia complexa, e sua etiologia é multifatorial e não entendida completamente. Cirurgia com avanço do músculo genioglosso é indicado em obstrução na região de hipofaringe. OBJETIVO: Avaliar a eficácia e complicações da técnica de mentoplastia para avanço do músculo genioglosso em pacientes com síndrome da apnéia-hipopnéia do sono obstrutiva (SAHSO). MÉTODOS: Polissonografia, exame físico e análise cefalométrica foram realizados em 10 pacientes não-obesos, que apresentavam SAHSO leve ou moderada, índice de apnéia-hipopnéia (IAH) entre 5 e 30, obstrução de hipofaringe e retrognatismo mandibular. RESULTADOS: IAH pré-operatório médio foi de 12,4±4,6 diminuindo a média pós-operatória para 4,4±5,7 (p < 0,001). Quando 50 por cento de redução do IAH pré-operatório foram escolhidos como parâmetro, o índice de sucesso foi de 70 por cento. A análise cefalométrica revelou um aumento do espaço aéreo posterior (EAP) em todos os pacientes, a média pré-operatória foi de 7,9±2,3mm para uma média pós-operatória de 10,8±2,5mm (p < 0,001). CONCLUSÃO: Mentoplastia para avanço do músculo genioglosso parece reduzir os sinais da SAHSO, podendo ser considerada uma opção com tratamento cirúrgico em pacientes com obstrução na hipofaringe. Os dados coletados indicam esse procedimento como opção em pacientes com SAHSO e retrognatismo mandibular.

Obstructive sleep apnea syndrome is a complex disease, which the etiology is multifactorial and incompletely understood. Surgery with genioglossus advancement is indicated in hypopharynx obstruction. AIM: evaluate the efficacy and complications of genioplasty technique for genioglossus muscle advancement in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). METHODS: polysomnography, physical examination and cephalometric analysis were performed in 10 non-obese patients, who presented mild or moderate OSAHS, an apnea-hypopnea index (AHI) between 5 and 30, with hypopharynx obstruction and mandibular retrognathia. RESULTS: the AHI preoperative mean of 12.4±4.6 decreased to a postoperative mean of 4.4±5.7 (p < 0,001). When 50 percent reduction of preoperative AHI was chosen as a parameter, its rate was 70 percent (7/10). Cephalometric analysis revealed an increase in the posterior airway space (PAS) in all patients, from a preoperative mean value of 7.9±2.3mm to a postoperative mean value of 10.8±2.5mm (p < 0,001). CONCLUSION: genioplasty for genioglossus advancement seemed to reduce OSAHS signs, thus, it can be considered as an option for the surgical treatment of patients with hypopharynx obstruction. Data collected supports this surgical procedure as an option in patients with OSAHS and mandibular retrognathia.
