Current opinion on laryngeal electromyography.

PURPOSE: This study evaluates expert opinion on laryngeal electromyography (LEMG). METHODS: A cross-sectional design was used to conduct an online survey of LEMG experts in 2021. They were questioned about the number LEMG performed annually, type of electrodes used, sector worked in, pain during the test, placement of the needle electrodes, interpretation of electrical muscle parameters, diagnosis of neuromuscular injury, prognostic sensitivity in vocal fold paralysis (VFP), laryngeal dystonia, tremor and synkinesis and quantifying LEMG. RESULTS: Thirty-seven professionals answered (23 Spanish and 14 from other countries), with a response rate of 21.56%. All physicians used LEMG. 91.9% had one- or two-years' experience and 56.8% performed 10-40 LEMG per year. 70.3% were otolaryngologists and 27%, neurologists. In 89.1% of cases, a team of electrodiagnostic physician and otolaryngologist performed LEMG. 91.3% of Spanish respondents worked in Public Health, 7.14% of other nationalities; 37.8% in a university department. Bipolar concentric needles electrodes were used by 45.9% and monopolar concentric by 40.5%. 57% professionals considered good patients' tolerance to the test. LEMG sensitivity was regarded as strong, median and interquartile range were 80.0 [60.0;90.0] to diagnose peripheral nerve injuries, less for other levels of lesions, and strong to evaluate prognosis, 70.0 [50.0;80.0]. Respondents believe locate the thyroarytenoid and the cricothyroid muscles with the needle, 80.0 [70.0;90.0], as opposed to 20.0 [0.00;60.0] the posterior cricoarytenoid. The interpretation of the electrical parts of the LEMG was strong, 80.0 [60.0;90.0]. LEMG identify movements disorders, 60.0 [20.0;80.0], and synkinesis, 70.0 [30.0;80.0]. The professionals prefer quantitative LEMG, 90.0 [60.0;90.0]. CONCLUSIONS: The experts surveyed consider LEMG that is well tolerated by patients. The insertional and spontaneous activity, recruitment and waveform morphology can be assessed easily. LEMG is mainly useful in the study of peripheral nerve injuries, and its value in VFP prognosis is considered strong.

Reconstruction of the lower lip after broad oncologic resection by Colmenero flap: a reliable option.

OBJECTIVE: Reconstruction of the lower lip is complex. The Colmenero flap is an effective albeit rarely described method for the repair of medium- to large-sized defects of the lower lip. METHODS: A retrospective review was carried out using data gathered from patients who had undergone Colmenero flap reconstruction of the lower lip at our centre between 2015 and 2020. We analysed demographic, histologic and anatomic variables as well as surgical results. This review assessed flap functionality based on proper mouth closure, absence of microstomia and oral competence. RESULTS: Thirteen Colmenero flaps were performed in 9 patients, with the flap being used bilaterally in four cases. All patients had squamous cell carcinoma of the lower lip. The mean length of the reconstructed defect was 4.1 cm (ranging between 3-7.5 cm). None of the flaps exhibited signs of necrosis. Five patients required minor surgical touch up during the second procedure: two for dehiscence, two for oral leakage and one for esthetic improvement. All patients had excellent functional and aesthetic final outcomes. CONCLUSIONS: The Colmenero flap is a good resource for medium- and large-sized lower lip reconstructions due to its reliability, limited complications, and good aesthetic and functional results.

Transoral laser microsurgery in locally advanced laryngeal cancer: Prognostic impact of anterior versus posterior compartments.

BACKGROUND: To evaluate the importance of larynx compartments in the prognosis of T3-T4a laryngeal cancer treated with transoral laser microsurgery. METHODS: Two hundred and two consecutive pT3-T4a larynx carcinomas. Pre-epiglottic space involvement, anterior and posterior paraglottic space (PGS) involvement, vocal cord, and arytenoid mobility were determined. Local control with laser (LC), overall survival (OS), disease-specific survival (DSS), and laryngectomy-free survival (LFS) were evaluated. RESULTS: The lowest LC was found in tumors with fixed arytenoid. In the multivariate analysis, positive margins (hazard ratio [HR] = 0.289 [0.085-0.979]) and anterior (HR = 0.278 [0.128-0.605]) and posterior (HR = 0.269 [0.115-0.630]) PGS invasion were independent factors of a reduced LC. Anterior (HR = 3.613 [1.537-8.495]) and posterior (HR = 5.195 [2.167-12.455]) PGS involvement were independent factors of total laryngectomy. Five-year OS, DSS, and LFS rates were 63.9%, 77.5%, and 77.5%, respectively. Patients with posterior PGS presented a reduced 5-year LFS. CONCLUSIONS: Tumor classification according to laryngeal compartmentalization depicts strong correlation with LC and LFS.

Clasificación de las resecciones transorales en la orofaringe: propuesta del grupo de trabajo de la Sociedad Catalana de Otorrinolaringología / Transoral oropharyngeal resection classification: Proposal of the SCORL working group

Introducción y objetivos: La cirugía mínimamente invasiva ha presentado una expansión muy importante en la última década. Con el objetivo de aportar un lenguaje común tras cirugía transoral de la orofaringe, se ha creado un sistema de clasificación de las resecciones en esta zona, independientemente de la instrumentalización utilizada. Métodos: Desde el Grupo de Trabajo en Oncología de la Sociedad Catalana de Otorrinolaringología, se presenta una propuesta de clasificación basada en una división topográfica de las diferentes zonas de la orofaringe, así como en la afectación de las estructuras anexas según las vías anatómicas de extensión de estos tumores. Resultados: La clasificación se inicia utilizando la letra D o I según la lateralidad sea derecha (D) o izquierda (I). A continuación se coloca el número del área resecada. Esta numeración define las zonas iniciando a nivel craneal donde el área I sería el paladar blando, el área II lateral en la zona amigdalina, el área III en la base de lengua, el área IV en los repliegues glosoepiglóticos, la epiglotis y repliegues faringoepiglóticos, el área V pared orofaríngea posterior y VI el trígono retromolar. Se añade el sufijo p si la resección afecta profundamente al plano submucoso de la zona comprometida. Las diferentes áreas propuestas tendrían, de una forma teórica, diferentes implicaciones funcionales. Conclusiones: Propuesta de sistema de clasificación por áreas que permite definir diferentes tipos de cirugía transoral de la orofaringe así como compartir los resultados y ayudar en la docencia de este tipo de técnicas (AU)

Introduction and goals: There has been a very significant increase in the use of minimally invasive surgery has in the last decade. In order to provide a common language after transoral surgery of the oropharynx, a system for classifying resections has been created in this area, regardless of the instrumentation used. Methods: From the Oncology Working Group of the Catalan Society of Otorhinolaryngology, a proposal for classification based on a topographical division of the different areas of the oropharynx is presented, as also based on the invasion of the related structures according to the anatomical routes of extension of these tumours. Results: The classification starts using the letter D or I according to laterality either right (D) or left (I). The number of the resected area is then placed. This numbering defines the zones beginning at the cranial level where area I would be the soft palate, lateral area II in the tonsillar area, area III in the tongue base, area IV in the glossoepiglottic folds, epiglottis and pharyngoepiglottic folds, area V posterior oropharyngeal wall and VI the retromolar trigone. The suffix p is added if the resection deeply affects the submucosal plane of the compromised area. The different proposed areas would, in theory, have different functional implications. Conclusions: Proposal for a system of classification by area to define different types of transoral surgery of the oropharynx, and enable as sharing of results and helps in teaching this type of technique (AU)

Malformación de Chiari tipo I como causa de disfagia orofaríngea. A propósito de un caso / Type I Chiari Malformation as a cause of oropharyngeal dysphagia. A case report

Introducción y objetivo: En este artículo se revisa un síntoma infrecuente que puede aparecer en la malformación de Chiari tipo I, la disfagia, cuya omisión puede excluir el diagnóstico o atribuirlo a otra patología. Paciente: Varón joven con cervicalgia y disfagia de 6 meses de evolución que consultó por disnea y fiebre. Ante la sospecha de neumonía broncoaspirativa se realizó una historia clínica completa y dirigida sobre las áreas topográficas que gobiernan la deglución y se realizaron toda una serie de pruebas complementarias para descartar otras causas de disfagia. La RM craneal confirmó el diagnostico de malformación de Chiari tipo I. El paciente fue intervenido quirúrgicamente mediante descompresión suboccipital. Pasados 6 meses mejoró la cervicalgia y desapareció la disfagia. Discusión: La disfagia es un síntoma inusual de la malformación de Chiari tipo I, debido a alteración por compresión del tronco encefálico y/o a elongación de los pares craneales bajos. Para lograr diagnósticos tempranos y el tratamiento adecuado, la exploración fí- sica debe ser completa y dirigida sobre las áreas topográficas que gobiernan la deglución, siendo básica la RM para establecer el diagnóstico causal. Conclusión: En pacientes con disfagia de origen incierto el diagnóstico de malformación de Chiari u otra causa de afectación de pares craneales bajos debe tenerse en cuenta (AU)

Introduction and objective: This article reviews an uncommon entity that may appear in Chiari malformation Type I, dysphagia, whose omission may exclude the diagnosis or attribute it to other pathology. Patient: Young male with dyspnea and fever who reported 6 month’s evolution neck pain and progressive dysphagia. Suspecting aspiration pneumonia, a complete and directed medical history on the topographical areas that govern swallowing and a series of additional tests, to rule out other causes of dysphagia, were held. Cranial MRI confirmed the diagnosis of type I Chiari malformation. The patient was surgically intervened through suboccipital decompression. 6 months after surgery there was an improvement in neck pain and dysphagia disappeared. Discussion: Dysphagia is an unusual symptom of type I Chiari malformation usually due to alteration by compression of the brainstem and/or to elongation of the lower cranial nerves. To achieve early diagnosis and proper treatment, the physical examination should be complete and directed over areas that govern swallowing, being MRI basic to establish causal diagnosis. Conclusion: Diagnosis of Chiari malformation or other causes of lower cranial nerves impairment must be kept in mind in patients with dysphagia of uncertain origin (AU)
