Treatment Results of Vocal Process Granuloma: Intubation versus Contact Granuloma

Abstract Introduction Contact granulomas (CGs) and intubation granulomas (IGs) are known to have different clinical manifestations despite having the same pathological features. Objectives The purpose of the present study was to analyze the treatment results for CG and IG and to obtain clinical information. Methods We retrospectively reviewed the medical records of patients diagnosed with vocal process granuloma (VPG) between January 2015 and December 2018. The patient's age, sex, medical history, lesion size, lesion type, reflux finding score (RFS), response to treatment, duration of treatment, and follow-up period were compared. Results Eighteen patients with CG and 14 patients with IG were included in the study. The IG group had more female patients (p = 0.0009), showed better response to proton pump inhibitor (PPI) and steroid inhalation (SI) (p = 0.036), and had a shorter treatment period (p = 0.0029) than the CG group. Five patients who received botulinum toxin injections in their vocal cords had complete remission. Conclusions Compared with CG, IG was more responsive to treatment with PPI and SI and required a shorter duration of treatment.

Rehabilitación del nervio recurrente laríngeo postiroidectomía / Recurrent laryngeal nerve rehabilitation after thyroidectomy

El carcinoma papilar tiroideo es el tipo de cáncer más común de esta glándula, y su tratamiento de elección es la tiroidectomía. Entre las complicaciones asociadas resalta la parálisis de las cuerdas vocales, la cual ocurre por una lesión directa del nervio laríngeo recurrente durante la cirugía. Se presenta una paciente de 22 años de edad con este diagnóstico, a la cual se le realizó una tiroidectomía total; en el postoperatorio inmediato la paciente comenzó con estridor laríngeo intenso que requirió una traqueotomía de urgencia. En el examen físico se constató una parálisis bilateral de las cuerdas vocales y se decidió comenzar un tratamiento de rehabilitación del nervio recurrente laríngeo con laserterapia y HIVAMAT-200 como modalidades combinadas. Los resultados alcanzados con la fisioterapia fueron satisfactorios y la paciente se reintegró rápidamente a su ámbito familiar, escolar y social.

Papillary thyroid carcinoma is the most common type of cancer of this gland, and its treatment of choice is thyroidectomy. Vocal cord paralysis stands out among the associated complications, in which a direct injury to the recurrent laryngeal nerve occurs during surgery. We present a 22-year-old female patient with this diagnosis, who underwent a total thyroidectomy; in the immediate postoperative period the patient began with intense laryngeal stridor requiring an emergency tracheotomy. Physical examination revealed bilateral vocal cord paralysis and it was decided to begin rehabilitation treatment of the recurrent laryngeal nerve with laser therapy and HIVAMAT-200 as combined modalities. The results achieved with physiotherapy were satisfactory and the patient was quickly reintegrated into her family, school and social environment.

Efficacy of routine exposure versus neuromonitoring of superior laryngeal nerve in thyroid cancer surgery / 中国基层医药

Objective:To investigate the efficacy of routine exposure versus neuromonitoring of the external branch of the superior laryngeal nerve (EBSLN) in thyroid cancer surgery. Methods:The clinical data of 500 patients who underwent open thyroid cancer surgery in the Department of Breast and Thyroid Surgery, People's Hospital of Quzhou from July 2017 to June 2020 were retrospectively analyzed. These patients were divided into a monitoring group ( n = 300) and an unmonitored group (control group) ( n = 200) according to whether neuromonitoring was performed during surgery. In the control group, the EBSLN was routinely exposed during the surgery for naked observation. In the monitoring group, the EBSLN was monitored. The Voice Handicap Index score, vocal cord function, and serum levels of parathyroid hormone and calcium ion were compared between the two groups before and after surgery. All patients were followed up for 1 year to observe injury to the EBSLN, parathyroid gland injury, and hypocalcemia. Results:In the monitoring group, operative time (112.32 ± 10.42) minutes, intraoperative blood loss (10.58 ± 5.04) mL, time to extubation (2.07 ± 0.54) days, postoperative drainage flow (10.55 ± 3.58) mL, and postoperative hospital stay (3.03 ± 1.03) days were significantly shorter and less compared with the control group ( t = 18.68, 15.09, 15.24, 32.98, 27.37, all P < 0.001). Compared with before surgery, normalized noise energy, amplitude perturbation, fundamental frequency perturbation, and fundamental frequency value in each group were significantly decreased after surgery, harmonic to noise ratio and the Voice Handicap Index were significantly increased after surgery. These indices were more obviously improved in the monitoring group compared with the control group ( t = 43.31, 27.10, 46.45, 37.11, 8.97, all P < 0.001). Compared with before surgery, serum levels of parathyroid hormone and calcium ion in each group were significantly decreased after surgery. After surgery, serum levels of parathyroid hormone and calcium ion in the control group were significantly lower than those in the monitoring group ( t = 41.14, 5.99, both P < 0.001). The incidence of complications in the monitoring group [4 cases of hypocalcemia (1.33%), 0 cases of parathyroid injury (0.00%), 8 cases of injury to the EBSLN] was significantly lower than that in the control group ( χ2 = 73.41, 74.17, 76.29, all P < 0.001). Conclusion:Neuromonitoring of the EBSLN during open thyroid cancer surgery can effectively improve patient voice and vocal cord function, reduce the rate of injury to the EBSLN, and has a clinical application value.

Risk Factors Analysis and Prevention Strategy of Renke Space Edema Complicated with Vocal Cord Adhesion After CO2 Laser Resection / 中山大学学报(医学科学版)

ObjectiveTo investigate the prevention strategy of bilateral vocal cord adhesion after simultaneous Renke space edema resection under CO2 laser. MethodsSeventy patients who underwent CO2 laser resection of bilateral Renke space edema of vocal cords from June 2018 to June 2021 in our hospital were retrospectively selected for this study. According to their postoperative vocal cord adhesion， patients were divided into vocal cord adhesion group （35 cases） and silent band adhesion group （35 cases）， and the general data of the two groups were compared. Multivariate logistic regression analysis was used to evaluate the risk factors for postoperative vocal cord adhesion. The prediction model of postoperative morbidity risk of vocal cord adhesion was established by using chisquared automatic interaction detection （CHAID） classification tree algorithm， and the application value of the model was evaluated by benefit graph and index graph. ResultsMultivariate analysis showed that surgical range and depth of Ⅱ， laser power≥5 W and anterior connection involvement were the risk factors for postoperative vocal cord adhesion ［OR 95%CI： 6.113 （2.346， 17.451）； 5.214 （1.469， 15.263）； 18.651 （1.689， 36.203）］. The classification tree model showed that anterior articulation involvement was an important predictor of postoperative vocal cord adhesion （76.92%； χ2=11.993， P=0.001）， and the benefit graph and index graph showed good models. ConclusionClinical attention should be paid to surgical scope and depth， laser power and anterior union involvement， and timely prevention strategies should be formulated to reduce the risk of vocal cord adhesion in patients.

Metástasis de cáncer de células claras renal en cuerdas vocales. Reporte de un caso / Metastasis of renal clear cell carcinoma in vocal cords. A Case report

Introducción: Las metástasis a distancia de tumores primarios a cuerdas vocales son poco frecuentes. Las metástasis a laringe con mayor frecuencia corresponden a melanomas y carcinomas, afectando principalmente a la región supraglótica. Las metástasis a cabeza y cuello de los carcinomas de células renales (CCR) tienen una incidencia de 14-16%. Se presenta el caso de un paciente con metástasis de carcinoma de células claras renal a cuerdas vocales, cuya importancia recae en que es un caso poco frecuente y no existen reportes similares en el país. Paciente masculino, 57 años, con disfonía de 3 meses de evolución. Nasofibroscopía evidencia lesión polipoídea en cuerda vocal y ventrículo izquierdo. Se realiza microcirugía laríngea, enviando muestra a biopsia diferida, resultando lesión metastásica de CCR células claras. Evaluado por nefrología, se pesquisa tumor renal izquierdo sugerente de CCR. Las metástasis de neoplasias remotas a laringe son infrecuentes. Se considera al CCR el tercero en frecuencia respecto a neoplasias infraclaviculares. Éstas se pueden presentar hasta 10 años después del tratamiento del primario. Se recomienda seguimiento a largo plazo y énfasis a nuevos síntomas en región de cabeza y cuello, teniendo en consideración antecedente de CCR en pacientes con disfonía y lesiones polipoídeas en cuerdas vocales.

Introduction: The metastasis of distant site primary tumors to the vocal cords is infrequent. The most frequent source of metastasis to the larynx is melanomas and carcinomas, mainly affecting the supraglottic region. The metastasis to the head and neck of renal cell carcinomas (RCC) has an incidence of 14-16%. To present a case of metastasis of clear renal cell carcinoma to the vocal cords, since it is very infrequent, and there are no similar reports in the country. A male patient, 57 years old, presenting dysphonia for a duration of 3 months. Nasofibroscopy showed a polypoid lesion in the left vocal cord and ventricle. Larynx microsurgery was performed, and a sample was sent for biopsy, which reported a metastatic lesion of RCC clear cells. When assessed by nephrology, a left renal tumor is found, suggesting RCC. The metastasis of distant site neoplasias are infrequent. RCC is considered the third in frequency concerning to infraclavicular neoplasias. These can present up to 10 years after the treatment of the primary. Long term follow-up is recommended, and an emphasis on new symptoms in the head and neck region, considering the history of RCC in patients with dysphonia and polypoid lesions in vocal cords.

Visual-perceptive assessment of glottic characteristics of vocal nodules by means of high-speed videoendoscopy

Abstract Objective Visual-perceptive assessment of glottic characteristics of vocal nodules by means of high-speed videoendoscopy. Methods Descriptive observational research with convenience sampling of five laryngeal videos of women with an average age of 25 years. The diagnosis of vocal nodules was defined by two otolaryngologists, with 100% intra-rater agreement and 53.40% inter-rater agreement and five otolaryngologists as judge assessed the laryngeal videos based on an adapted protocol. The statistical analysis calculated measures of central tendency and dispersion, as well as percentage. The AC1 coefficient was used for agreement analysis. Results In high-speed videoendoscopy imaging, vocal nodules are characterized by amplitude of the mucosal wave and muco-undulatory movement with magnitude between 50% and 60%. Non-vibrating segments of vocal folds are scarce, and the glottal cycle does not show a predominant phase, it is symmetric and periodic. Glottal closure is characterized by the presence of a mid-posterior triangular chink (double chink or isolated mid-posterior triangular chink), without movement of supraglottic laryngeal structures, with irregular contour of the free edge of vocal folds, which are vertically on-plane. Conclusion Vocal nodules present mid-posterior triangular chink and irregular free edge contour. Amplitude and mucosal wave were partially reduced. Level of evidence: Level 4 (Case-series).

Obstrucción laríngea inducible (OLI): una revisión actualizada de la literatura

La obstrucción laríngea inducible se ha descrito como un trastorno de la respiración que se presenta, habitualmente, como dificultad respiratoria aguda por aducción anormal de los pliegues vocales, típicamente, durante la inspiración. Es más frecuente en mujeres y adultos, que en adolescentes. Es difícil estimar la incidencia exacta dada la heterogeneidad de los criterios diagnósticos y nomenclatura, asociado al frecuente subdiagnóstico de esta entidad. Por ello, en la literatura se ha reportado la prevalencia de acuerdo con las subpoblaciones de pacientes, describiendo que alrededor de un 2,8% de los pacientes que consultan en el servicio de urgencia por disnea podría corresponder a esta patología. El diagnóstico es eminentemente clínico, con confirmación mediante laringoscopia flexible. Se apoya en exámenes de función respiratoria, especialmente para descartar otras patologías pulmonares que expliquen el cuadro. El tratamiento es sencillo y, suele ser exitoso, tanto en situaciones agudas como crónicas. Sin embargo, se ha descrito, frecuentemente, un retraso en el diagnóstico, debido a desconocimiento de esta patología.

Induced laryngeal obstruction has been described as a respiratory disorder, usually presenting as an acute respiratory distress due to abnormal adduction of the vocal folds, typically during inspiration. It is more frequent in women and adults, than adolescents. It is difficult to estimate its exact incidence given the heterogeneity of the diagnostic criteria and nomenclature, together with its common underdiagnosis. Hence, studies have reported its prevalence according to the subpopulations within this entity, with a prevalence of 2.8% in patients who consult in the emergency room for dyspnea. The diagnosis is based upon clinical presentation, confirmed by flexible laryngoscopy, and supported by respiratory function exams to rule out other pulmonary diseases with similar symptoms. Its treatment is simple and usually successful, in both acute and chronic situations. However, a delay in the diagnosis has been frequently described, due to unawareness of this disorder.

Clinical Predictors of Postintubation Bilateral Vocal Fold Immobility

Abstract Introduction Iatrogenic bilateral vocal fold immobility (BVFI) often arises from posterior glottic stenosis (PGS) after endotracheal intubation, whereby posterior commissure mucosal disruption leads to fibrosis and ankylosis of the cricoarytenoid joints. Sequelae can be devastating, resulting in dyspnea, stridor, and death due to asphyxiation. Objectives We sought to review features associated with PGS to better understand how to prevent this condition. A secondary aim is to analyze factors correlating to tracheostomy dependence. Methods Charts from January 2010 to November 2020 were retrospectively reviewed, and adult patients with the diagnosis of BVFI after intubation were included. Data on comorbidities, duration of intubation, laryngoscopy, and decannulation status was analyzed. Results Out of the 68 patients included in the present study, 60.3% were male, and the mean duration of intubation 14.3 ± 8.5 days. A total of 94% of the patients were intubated for at least 7 days, diabetic, and/or obese. Although association with prolonged intubation >7 days was not significant (p = 0.064), complete BVFI on fiberoptic exam (n = 47) was significantly associated with tracheostomy dependence both in the entire cohort (p = 0.036) and in the 56 patients with tracheostomy (p = 0.0086). Patients without cardiovascular disease (CVD) were less likely to be tracheostomy dependent compared with those with CVD (odds ratio [OR]: 0.23 [0.053-0.79]; p = 0.028). Conclusions We identified duration of intubation, DM, and obesity as potential risk factors for PGS. Complete immobility and CVD were significantly associated with tracheostomy dependence. Our findings may have important implications for earlier tracheostomy in high-risk intubated patients, as well as for closer monitoring of disease progression and earlier intervention in those predisposed to tracheostomy dependence.

Neuropatía laríngea y movimiento paradojal de cuerdas vocales en la edad pediátrica: reporte de un caso / Laryngeal neuropathy and paradoxical vocal fold motion in the pediatric age: case report

Resumen La neuropatía laríngea es una condición de hipersensibilidad, hiperreactividad e hiper-función laríngea secundaria a un desequilibrio entre las aferencias y eferencias laríngeas. La respuesta individual y exagerada frente a diversos gatillantes específicos puede generar síntomas como tos crónica, parestesia laríngea, carraspera, disfonía, estridor, sensación de globus faríngeo, movimiento paradojal de las cuerdas vocales (también conocido como disfunción cordal) y/o laringoespasmo. Existe abundante literatura sobre neuropatía laríngea en adultos, sin embargo, en niños es limitada. El objetivo de este artículo es dar a conocer un caso de neuropatía laríngea en la edad pediátrica y la importancia de su consideración en el enfrentamiento de estos pacientes. Se presenta caso clínico de un paciente de 13 años, con antecedente de cirugía cardiaca reciente, evoluciona con disfonía severa evidenciándose aparente inmovilidad cordal bilateral con resultados discordantes entre nasofibrolaringoscopía y electromiografía laríngea. Posteriormente presenta mejorías en su voz, sin embargo, se agregan otros síntomas laringológicos como carraspera, globus faríngeo y estridor no explicados por causas anatómicas. Se expone la evaluación y abordaje otorrinolaringológico-fonoaudiológico para el caso. Se concluye que el diagnóstico de neuropatía laríngea requiere un alto índice de sospecha clínica ante signos laringológicos sugerentes, debiendo descartarse causas orgánicas y estructurales. El abordaje otorrinolaringológico-fonoaudiológico constituye el pilar terapéutico asociado al uso de neuromoduladores en casos seleccionados.

Abstract Laryngeal neuropathy is a condition of hypersensitivity, hyperresponsiveness and laryngeal hyperfunction secondary to an imbalance between laryngeal afferent and efferent information. The individual and exaggerated response to diverse specific triggers can lead to symptoms such as chronic cough, laryngeal paresthesia, throat clearing, dysphonia, stridor, globus pharyngeus, vocal cord dysfunction, and/or laryngospasm. There is plentiful literature on laryngeal neuropathy in adults, however, in children, it is limited. Here, we present a case report of laryngeal neuropathy in the pediatric age and discuss the importance of its consideration in the approach of these patients. A case of a 13-year-old patient, recently intervened with cardiac surgery that evolves with severe dysphonia is presented. Nasofibrolaryngoscopy shows apparent bilateral vocal fold immobility with discordant results in laryngeal electromyography. Later, his voice improves but other laryngological symptoms appeared, such as throat clearing, globus pharyngeus and stridor, not explained by anatomical causes. The otolaryngological-speech therapy evaluation and approach for the case is exposed. We conclude that for the diagnosis of laryngeal neuropathy, a high index of clinical suspicion is required in the presence of suggestive laryngological symptoms, and organic and structural causes must be previously ruled out. The otorhinolaryngological-logopedic approach constitutes the mainstay of treatment associated with the use of neuromodulators in selected cases.

Intubación endotraqueal de emergencia en paciente con estridor inspiratorio y hallazgo de tumor en cuerdas vocales: reporte de un caso / Emergency endotracheal intubation in a patient with inspiratory stridor and a vocal cord tumour finding: a case report

El manejo especializado de la vía aérea (VA) es fundamental en las unidades de urgencia donde la intubación orotraqueal ha sido la técnica de elección para lograrlo. Una VA difícil se define como una situación clínica en la cual un equipo médico entrenado experimenta dificultades en la ventilación y/o en intubación. La obstrucción aguda de la VA constituye una de las emergencias médicas más extremas, requiriendo intervención inmediata. Se presenta el caso de un paciente con estridor inspiratorio con criterios inmediatos de intubación donde se evidencia un tumor en cuerdas vocales con obstrucción de la vía aérea.

Specialized airway management is essential in emergency units where endotracheal intubation has been the technique of choice. The difficult airway is defined as a clinical situation in which a trained medical team experiences difficulties in ventilation and, or intubation. Acute airway obstruction is one of the most extreme medical emergencies, requiring immediate intervention. We present the case of a patient with inspiratory stridor with quick criteria for intubation where a tumour in the vocal cords with airway obstruction is found.

Preliminary study of high-frequency ultrasound in the diagnosis of vocal cord polyps / 中华超声影像学杂志

Objective:To explore the characteristics of vocal cord polyps and to study the application value of high-frequency ultrasound in the diagnosis of vocal cord polyps.Methods:A total of 169 patients diagnosed with vocal cord polyps ( 176 polyps in total ) by pathology in the Second Affiliated Hospital of Xi′an Jiaotong University from December 2016 to September 2021 were collected, the ultrasonic image characteristics of vocal cord polyps were summarized, and the characteristics of thyroid cartilage calcification at glottic level and the influence of the calcification range of thyroid cartilage at glottic level on the display of vocal cord polyps were observed.Results:The sonogram images of all vocal cord polyps showed the localized uniform low echo between the upper cortex and the ligament layer, the morphology could be circular and flat, and all polyps could be divided into high tension type and low tension type, no blood flow signal was found in 96.8% of the polyps. Round polyps were more easier to be detected by ultrasound than flat polyps, but there was no significant difference( P>0.05). The incidence of thyroid cartilage calcification at glottis level was higher in men than in women, and the difference was statistically significant( P<0.05). The range of thyroid cartilage calcification at the glottic level affects the display rate of vocal cord polyps.With the increase of calcification range, the display rate of vocal cord polyps gradually decreased. There was significant difference in the display rate of vocal cord polyps between non calcification group and moderate calcification group, non calcification group and severe calcification group(all P<0.05). Conclusions:Vocal cord polyps have typical sonographic appearance. High-frequency ultrasound can identify the morphology, location and size of vocal cord polyps. Especially for patients with no or mild calcification of thyroid cartilage at glottic level, ultrasound can meet the requirements of accurate diagnosis. It is expected to become an effective supplement to laryngoscopy, and apply for to the preliminary screening of vocal cord polyps and postoperative review.

Síndrome de Tapia posterior a cirugía nasal

Resumen El síndrome de Tapia es una complicación poco frecuente secundaria a la manipulación de la vía aérea. Se caracteriza por haber una lesión concomitante de los pareas craneales X (nervio vago) y XII (nervio hipogloso), usualmente por compresión o sobredistensión de estos. Inicialmente puede hacernos sospechar una lesión central, al haber compromiso de dos nervios craneales bajos en forma simultánea, pero la gran mayoría de los casos descritos son lesiones periféricas. De los procedimientos asociados a esta complicación, los que lideran en frecuencia son los de cabeza y cuello, por lo que es de gran importancia tenerlo en conocimiento en el desarrollo de nuestra práctica clínica. Nuestro paciente presentó esta complicación tras una septoplastía con turbinectomía sin complicaciones en el sitio operatorio, ni anestésicas. Se manejó con fonoaudiología y corticoides orales, con recuperación completa a los cuatro meses de posoperatorio.

Abstract Tapia's Syndrome is a rare complication secondary to airway manipulation. It is characterized by a concurrent lesion of cranial nerve pairs X (vagus nerve) and XII (hypoglossal nerve), usually attributed to compression or stretching of these nerves. Initially, it may lead us to suspect a central lesion, as there is simultaneous involvement of two low cranial nerves, but the vast majority of cases described are peripheral lesions. The procedures most frequently associated with this complication are head and neck surgery, which is why it is very important to bear this in mind in the development of our clinical practice. Our patient showed Tapia's syndrome following septoplasty with turbinectomy without complications in the operative site nor under anesthesia. He was treated with phoniatric and oral corticoids, recovering completely four months after surgery.

El niño con estridor persistente / The child with persistent stridor

El estridor es un ruido respiratorio anormal generado por obstrucción o colapso de la vía aérea laringotraqueal, de manera aguda o de evolución crónica. Existen distintas causas tanto congénitas como adquiridas capaces de producir dificultad respiratoria, que puede llegar a ser grave y con potencial riesgo vital. El diagnóstico clínico del paciente con estridor persistente debe ser complementado con un estudio endoscópico de la vía aérea y en ocasiones con imágenes, para intentar determinar el o los sitios comprometidos y posibles malformaciones asociadas. La indicación de tratamiento debe ser individualizada, considerando el estado general del paciente, las etiologías responsables, el im pacto sobre la respiración y la deglución, el pronóstico y la capacidad técnica del equipo tratante, entre otras. Las alternativas pueden incluir observación, medidas no farmacológicas, medicamentos locales o sistémicos, procedimientos endoscópicos, cirugías abiertas, o bien la instalación de una traqueostomía de manera temporal o como manejo definitivo. El objetivo de esta revisión es entregar un adecuado conocimiento de la fisiopatología y la etiopatogenia del estridor pediátrico persistente, fundamental para el correcto manejo de estos pacientes complejos, que debiera realizarse idealmente en un contexto multidisciplinario.

Stridor is an abnormal respiratory sound caused by obstruction or collapse of the laryngotracheal airway, either acutely or chronically. There are different causes, both congenital and acquired, that can produce shortness of breath which may be severe and potentially life-threatening. The clini cal diagnosis must be complemented with an endoscopic airway assessment and sometimes with imaging, to try to determine the areas involved and possible associated malformations. Treatment should be individualized, considering the patient's overall condition, stridor etiology, its impact on breathing and swallowing, prognosis, and technical capacity of the managing team, among others. Alternatives may include observation, non-pharmacological measures, local or systemic medications, endoscopic and open surgeries, or a temporary or long-term tracheostomy. A thorough understan ding of the pathophysiology and etiopathogenesis of persistent pediatric stridor is essential for the correct management of these complex patients, ideally in a multidisciplinary manner.

Proportion of Human Papilloma Virus in Squamous Epithelial Lesions of Head and Neck- A Polymerase Chain Reaction Study

Human Papilloma Viruses (HPV) have been implicated to cause 5% of human cancers. The role of HPV as an etiological agent in the development of precancerous lesions and cancers of head and neck is increasingly being explored. The wide variation in prevalence of HPV has, to some extent, impeded a full understanding of association between HPV and benign and malignant lesions of head and neck. We wanted to determine the proportion of Human Papilloma Virus in squamous epithelial lesions of head and neck using Polymerase Chain Reaction (PCR) studying snap frozen fresh biopsy samples.METHODSThis is a descriptive study of cases presenting to the Department of Pathology, Govt. T D Medical College, Alappuzha, Kerala, conducted over a period of one year. 40 cases of clinically suspicious premalignant or malignant squamous lesions of head and neck were biopsied and were subjected to histopathological study and PCR using primer MY11/GP6. Data was entered in Excel sheet. The association of HPV positivity with lesions of head and neck was assessed using SPSS softwareRESULTSOf the 40 cases studied, the mean age of the cases studied was 55.98 years. Male to female ratio was 29:11. Most of the cases were alcoholics (60%), with smokers (55%) and the habit of pan chewing in 20% of the cases. The histopathological lesions studied were mostly malignant cases (squamous cell carcinoma- 77.5% of cases) and rest were oral keratosis, vocal cord polyp and a lesion showing chronic inflammation only. The predominant site of biopsy was from oral cavity (80%), followed by larynx (16%) and oropharynx (13%). HPV positivity was obtained in 2.5% of the cases, which was not statistically significant. HPV positivity did not show statistically significant association with any of the risk factor behaviours like alcoholism, smoking or pan chewing. The morphological diagnosis associated with HPV was moderately differentiated, which was also not statistically significant.CONCLUSIONSHPV positivity was obtained in 2.5% of the cases studied with no significant correlation between HPV and squamous epithelial lesions of head and neck.

Ortner's syndrome

Inferior laryngeal nerve palsy is a relatively common entity. Nevertheless, an occurrence as a result of a cardiovascular pathology is rare. In this case, it is called Ortner's syndrome (OS). Aortic diseases are responsible for more than half of cases. Supraaortic vessels disorders are rare causes of OS. In our new report, a non-smoker and non-drinker 70-year-old woman presented with a history of dysphonia since childhood. On direct laryngoscopy, a left vocal cord paralysis was detected and a contrast-enhanced computed tomography showed an aberrant right subclavian artery originating from the left portion of the aortic arch. Its course to its usual site runs behind the esophagus, being also called arteria lusoria. In this particular case, two unusual situations appear together, which contributes to the rarity of the event.(AU)

Value of pathogenic diagnosis of 18F-FDG PET/CT imaging in non-traumatic unilateral vocal cord paralysis / 中华核医学与分子影像杂志

Objective To evaluate the diagnostic value of 18F-fluorodeoxyglucose (FDG) PET/CT imaging in non-traumatic unilateral vocal cord paralysis (UVCP) and compare the radioactive uptake in different lesions.Methods Clinical data of 62 patients (49 males,13 females;age:(61.7±12.8) years)with non-traumatic UVCP (43 cases of left vocal cord paralysis and 19 cases of right) admitted to Ji'an Hospital from January 2016 to December 2018 were analyzed retrospectively.Pathological results,imaging or follow-up results were considered as the standard of final diagnosis.The diagnostic efficacy of PET/CT imaging for the primary cause was analyzed.The maximum standardized uptake values (SUVmax) of vocal cord in patients with different etiology were compared by independent-sample t test.Results According to the final diagnosis,the primary causes of UVCP were as follows:malignant tumors (n=44),inflammation (n=16),glomus jugulare tumor (n =1) and idiopathic UVCP (n =1).The diagnostic accuracy of PET/CT imaging for the primary cause was 90.32％ (56/62):44 cases were correctly diagnosed as malignant tumors,while 11 cases as inflammation,and 1 case as glomus jugulare tumor.Among 62 patients,29 patients had increased SUVmax in the affected side (direct invasion group;further divided into tumor group (n =12) and non-tumor group (n =17)),and other 33 patients had increased SUVmax in the healthy side (indirect invasion group).SUVmax of the affected vocal cord in direct invasion group was higher than that in the healthy side (9.97±5.21 vs 2.43±0.62;t=8.14,P＜0.01).The differences between affected side and healthy side in the tumor group (14.92±3.91 vs 2.84±0.54) and the non-tumor group (6.48±2.48 vs 2.14±0.50) were statistically significant (t values:9.94,7.93,both P＜0.01).In the indirect invasion group,SUVmax in the affected side of vocal cord was significantly lower than the healthy side (1.89±0.35 vs 6.97±2.63;t =11.44,P＜0.01).There were significant differences in radioactive uptake between affected side of direct invasion group and healthy side of indirect invasion group (t =2.86,P＜0.01),affected sides of tumor group and non-tumor group (t=7.46,P＜0.01),affected side of tumor group and healthy side of indirect invasion group (t=6.07,P＜0.01).But the radioactive uptake difference between affected side of non-tumor group and healthy side of indirect invasion group was not statistically significant (t =0.51,P＞0.05).Conclusions 18F-FDG PET/CT imaging has high diagnostic value in pathogenic diagnosis of non-traumatic UVCP.The different radioactive uptake of vocal cords in the affected side and the healthy side provides more accurate etiological information for clinical analysis.

Vocal Training for Patients Post Vocal Cord Polyp Surgery Based on ICF and ICHI / 中国康复理论与实践

Objective:To explore the effect of vocal training based on International Classification of Functioning, Disability and Health (ICF) and International Classification of Health Interventions (ICHI) on vocal function after vocal cord polyps. Methods:A framework of rehabilitation was developed with joint use of ICF and ICHI. From January, 2017 to December, 2018, 30 patients with vocal cord polyps and vocal dysfunction post operation were sampled. They accepted the therapy for a month, and assessed with Grade, Roughness, Breathiness, Asthenia and Strain scale (GRBAS), and measured acoustic parameters before and after operation, and after training, respectively. Results:The scores of GRBAS decreased after training, compared with those both before and after operation (F > 6.214, P < 0.05), as well as the acoustic parameters of fundamental frequency, fundamental frequency perturbation, normalized noise energy and amplitude perturbation (F > 9.655, P < 0.05). Conclusion:Vocal training based on ICF and ICHI is effective on vocal function after operation for vocal cord polyps.

The diagnostic accuracy of PET/CT imaging for the primary cause was 90.32%(56/62): 44 cases were correctly diagnosed as malignant tumors, while 11 cases as inflammation, and 1 case as glomus jugulare tumor. Among 62 patients, 29 patients had increased SUVmax in the affected side (direct invasion group; further divided into tumor group (n=12) and non-tumor group (n=17)), and other 33 patients had increased SUVmax in the healthy side (indirect invasion group). SUVmax of the affected vocal cord in direct invasion group was higher than that in the healthy side (9.97±5.21 vs 2.43±0.62; t=8.14, P<0.01). The differences between affected side and healthy side in the tumor group (14.92±3.91 vs 2.84±0.54) and the non-tumor group (6.48±2.48 vs 2.14±0.50) were statistically significant (t values: 9.94, 7.93, both P<0.01). In the indirect invasion group, SUVmax in the affected side of vocal cord was significantly lower than the healthy side (1.89±0.35 vs 6.97±2.63; t=11.44, P<0.01). There were significant differences in radioactive uptake between affected side of direct invasion group and healthy side of indirect invasion group (t=2.86, P<0.01), affected sides of tumor group and non-tumor group (t=7.46, P<0.01), affected side of tumor group and healthy side of indirect invasion group (t=6.07, P<0.01). But the radioactive uptake difference between affected side of non-tumor group and healthy side of indirect invasion group was not statistically significant (t=0.51, P>0.05).@*Conclusions@#18F-FDG PET/CT imaging has high diagnostic value in pathogenic diagnosis of non-traumatic UVCP. The different radioactive uptake of vocal cords in the affected side and the healthy side provides more accurate etiological information for clinical analysis.
