Guía de práctica clínica sobre el manejo del schwannoma vestibular / Clinical practice guideline on the management of vestibular schwannoma

Introducción: El schwannoma vestibular (SV) es el tumor más frecuente del ángulo pontocerebeloso. La mayor accesibilidad a las pruebas radiológicas ha incrementado su diagnóstico. Teniendo en cuenta las características del tumor, la clínica y la edad del paciente se han propuesto tres estrategias terapéuticas, observación, cirugía o radioterapia. La elección de la más adecuada para cada paciente es un motivo de controversia frecuente. Material y métodos: El presente trabajo incluye una revisión exhaustiva sobre cuestiones relativas al SV que pueden servir de guía clínica en el manejo de pacientes con estas lesiones. La presentación se ha orientado en forma de preguntas que el clínico se hace habitualmente y las respuestas están redactadas y/o revisadas por un panel de expertos nacionales e internacionales consultados por la Comisión de Otología de la SEORL-CCC. Resultados: Se ha elaborado un listado con los 13 bloques temáticos más controvertidos sobre el manejo del SV en forma de 50 preguntas y se han buscado las respuestas a todas ellas mediante una revisión sistemática de la literatura (artículos publicados en PubMed y Cochrane Library entre 1992 y 2023 sobre cada bloque temático). Treinta y tres expertos, liderados por la Comisión de Otología de la SEORL-CCC, han analizado y discutido todas las respuestas. En el Anexo 1 pueden encontrarse 14 preguntas adicionales divididas en cuatro bloques temáticos. Conclusiones: Esta guía de práctica clínica sobre el manejo del SV ofrece respuestas consensuadas a las preguntas más habituales que se plantean sobre este tumor. La ausencia de suficientes estudios prospectivos hace que los niveles de evidencia sobre el tema sean en general medios o bajos. Este hecho incrementa el interés de este tipo de guías de práctica clínica elaboradas por expertos.(AU)

IntroductionVestibular schwannoma (VS) is the most common tumour of the cerebellopontine angle. The greater accessibility to radiological tests has increased its diagnosis. Taking into account the characteristics of the tumour, the symptoms and the age of the patient, three therapeutic strategies have been proposed: observation, surgery or radiotherapy. Choosing the most appropriate for each patient is a frequent source of controversy. Material and methods: This paper includes an exhaustive literature review of issues related to VS that can serve as a clinical guide in the management of patients with these lesions. The presentation has been oriented in the form of questions that the clinician usually asks himself and the answers have been written and/or reviewed by a panel of national and international experts consulted by the Otology Commission of the SEORL-CCC. Results: A list has been compiled containing the 13 most controversial thematic blocks on the management of VS in the form of 50 questions, and answers to all of them have been sought through a systematic literature review (articles published on PubMed and Cochrane Library between 1992 and 2023 related to each thematic area). Thirty-three experts, led by the Otology Committee of SEORL-CCC, have analyzed and discussed all the answers. In Annex 1, 14 additional questions divided into 4 thematic areas can be found. Conclusions: This clinical practice guideline on the management of VS offers agreed answers to the most common questions that are asked about this tumour. The absence of sufficient prospective studies means that the levels of evidence on the subject are generally medium or low. This fact increases the interest of this type of clinical practice guidelines prepared by experts.(AU)

Lista de verificación de tomografía computarizada de hueso temporal y base de cráneo lateral / Checklist of the temporal bone and lateral skull base CT- scan

La tomografía computarizada del hueso temporal es una prueba de imagen fundamental para el diagnóstico y tratamiento de diversas entidades que afectan a esta compleja estructura. La tomografía computarizada permite una representación más detallada de las estructuras óseas que la resonancia magnética, lo que determina que sea la prueba de elección para la planificación de la cirugía otológica.El objetivo de este trabajo es el de elaborar una lista de verificación o checklist que permita al otorrinolaringólogo estudiar y valorar de forma sistemática y organizada las principales estructuras de referencia, variantes anatómicas y cambios posquirúrgicos más frecuentes antes de una cirugía segura.Esta revisión ha sido promovida por la Sociedad Española de Otorrinolaringología y redactada en un formato de lista de verificación dividida en las diferentes regiones del hueso temporal y base de cráneo lateral. (AU)

Computed tomography scan of the temporal bone is a fundamental imaging modality for both the diagnosis and treatment of a wide range of pathologies affecting this complex structure. Temporal bone computed tomography scan provides a more detailed depiction of bone structures, compared with magnetic resonance imaging and, for this reason computed tomography scan is the imaging modality of choice in the planning of otological surgery.The aim of this article is to present a checklist to allow the otolaryngologist to assess systematically and in an organized manner the main anatomical landmarks, anatomical variants, as well as the most common postoperative surgical changes, which can be identified before any safe otological surgery.This revision was promoted by the Spanish Society of Otolaryngology and elaborated in a checklist template divided into the different areas of the temporal bone and the lateral skull base.

Effect of Tinnitus in Distortion Products Otoacoustic Emissions (DPOAEs) in Normal Hearing Patients.

Tinnitus is a symptom whose pathophysiology remains still unclear. Its diagnosis and treatment is complicated, due to its subjectivity. The generation of tinnitus is commonly linked with the impaired functioning of the outer hair cells (OHC) inside the cochlea. Distortion product otoacoustic emissions (DPOAEs) are the objective test used to assess their activity. This study investigates the cochlear outer hair cell function in patients with tinnitus and normal hearing using DPOAEs. We performed a prospective study of the cochlear function in normal hearing patients complaining of tinnitus by analysing DPOAEs amplitude and signal/noise (S/N) ratio. We gathered a sample of 21 ears from adults that attended to the ENT Department complaining of tinnitus with normal hearing. We compared their results with a control group of 21 ears, with the same demographic characteristics, presenting normal hearing but without tinnitus in order to exclude the influence of age in DPOAEs results. A decreased mean of S/N levels in DPOAEs was found in tinnitus and normal hearing group comparing with control group, although these differences were not statistically significant (p > 0.05). Based on the results, OHC dysfunction is not necessary to experience tinnitus. The majority of the patients that present OHC dysfunction do not present a tinnitus at the moment. Other mechanisms in auditory pathway may be evaluated in the tinnitus development.

Validation of the Spanish Version of the STOP-Bang Questionnaire: Usefulness as a Screening Tool for Obstructive Sleep Apnea in Adults.

OBJECTIVES: Obstructive sleep apnea syndrome (OSAS) is an increasing health problem, the diagnosis of which is generally delayed due to long waiting lists for the tests used to identify it. Therefore, tools that help on classifying patients at higher risk of suffering this syndrome have been developed. METHODS: One hundred ninety-three consecutive patients, with and without OSAS, filled in the Spanish version of the STOP-Bang questionnaire in Hospital Universitario de Torrejón (Spain). Polysomnographies were performed to diagnose the presence and severity of the OSAS. Statistics analysis of the demographic characteristics of the sample and the questionnaire results was performed. RESULTS: Most patients were male (73%) and the mean age was 50.4 years (ranging from 19-77 years). Cronbach α coefficient in the sample was 0.8072. A statistically significant difference was noted in the questionnaire scores between patients with OSAS and those without the syndrome. CONCLUSIONS: The Spanish version of the STOP-Bang questionnaire possess a good internal consistency that allows us to rely on it as a screening tool for patients with OSAS. In our sample, a difference in the questionnaire score was appreciated between patients with and without the syndrome, which strongly supports the utility of the questionnaire for its purpose.

Cepstral analysis in patients with a vocal fold motility impairment: advantages of the cepstrum over time-based acoustic analysis.

OBJECTIVES: To determine the usefulness of the smoothed cepstral peak prominence (CPPS) in sustained vowel as objective measure of dysphonia. STUDY DESIGN: This is a retrospective cohort study. 49 patients presenting a vocal cord motility impairment between 2012 and 2018 were included. METHODS: Classical acoustic parameters, including jitter, shimmer and NHR, as well as the CPPS were obtained for each patient with a vocal cord motility impairment confirmed by means of a fiberoptic laryngoscopy. We calculated the S/E ratio of each patient to establish the glottal efficiency. An independent sample t test and a Pearson correlation test were used to compare data. RESULTS: Patients presenting a vocal cord motility impairment present abnormal values of the CPPS. Those patients presenting a vocal cord paralysis present lower values of those presenting a vocal cord paresis, with statistically significant difference (P < 0.005). CPPS and the S/E ratio present a moderate negative correlation (- 0.29). CONCLUSIONS: Subjects with a vocal cord motility impairment present abnormal values for CPPS and those values are lower, the greater the motility impairment is. Therefore, CPPS presents as an objective, measurable and reproducible acoustic parameter of dysphonia that will improve the evaluation of patients presenting vocal pathologies.

Síndrome de Horner secundario a cirugía cervical / Horner's syndrome after neck surgery

El síndrome de Horner (oculosimpatoparesis) consiste en la clásica triada de ptosis palpebral, miosis pupilar y anhidrosis facial ipsilateral. El síndrome resulta tras la interrupción de la inervación simpática del ojo y de los anexos oculares a diferentes niveles, siendo una complicación poco frecuente de la cirugía cervical. Describimos los casos de 6 pacientes que presentaron síndrome de Horner tras cirugía cervical en nuestro servicio en los últimos 5 años y una revisión de los diferentes procedimientos cervicales que producen dicha entidad(AU)

Horner's syndrome (oculosympathetic paresis) is characterised by the classic triad of ipsilateral palpebral ptosis, pupillary miosis and facial anhidrosis. The syndrome arises from the interruption of sympathetic innervation to the eye and adnexa at varying levels. It is a rare complication of neck surgery. We describe 6 patients who presented with Horner's syndrome after a neck procedure in our department during the last 5 years and review the different neck procedures that can cause it(AU)

Traumatismos cervicales / Neck injuries

Introducción y objetivo: Los traumatismos cervicales tienen un gran interés clínico dado que se asocian a una elevada morbimortalidad si no son manejados adecuadamente. El objetivo de nuestro estudio fue revisar los traumatismos cervicales externos en nuestro hospital. Material y métodos: Se realizó un estudio descriptivo retrospectivo que incluyó a pacientes que presentaron lesiones penetrantes de cuello tratadas por el Servicio de ORL en un hospital terciario durante 24 años. Resultados: Veintidós pacientes fueron incluidos en nuestro estudio. Un 45% de los casos fueron secundarios a accidentes de tráfico, un 27,3% a una agresión con arma blanca y un 23% a un intento de suicidio. En 15 casos (68%) constituían traumatismos abiertos y en 7 cerrados (31%). El síntoma más frecuente de presentación fue la hemorragia (55%), seguido de trastornos respiratorios (23%). En la exploración, en un 27% de los pacientes se detectó un enfisema subcutáneo. En un 50% de los casos se realizaron técnicas de imagen antes del tratamiento, siendo la más frecuente la tomografía computarizada de cuello (27%). Un 59,1% de los pacientes requirieron tratamiento quirúrgico, precisando una traqueotomía en 6 casos (27%), falleciendo por complicaciones hemorrágicas dos de ellos (9%). Otros 6 pacientes presentaron secuelas permanentes. Conclusiones: Los traumatismos cervicales con afectación de estructuras otorrinolaringológicos son infrecuentes en nuestro medio, siendo las más habituales las secundarias a accidentes de tráfico. Es importante tener protocolizado el manejo de estos pacientes ya que con frecuencia pueden presentar complicaciones severas o incluso la muerte, si no son tratados adecuadamente en un corto período de tiempo (AU)

Introduction and objective: Neck injuries are of great clinical interest because they can induce very significant consequences if not handled properly and can even lead to death. The aim of our study was to analyse external deep cervical trauma in our hospital. Material and methods: A retrospective study of all external deep neck injuries seen in a tertiary hospital over the course of 24 years that involved changes in structures related to otolaryngology. Results: Twenty patients were included in our study. From all the injuries, 45% were secondary to traffic accidents, 27% from assault with a knife and 23% from attempted suicide. The injuries were open in 15 (68%) cases and closed in 7 (32%). The most common symptom was bleeding (55%), followed by respiratory disorders (23%). On examination, the most frequent sign was the appearance of subcutaneous emphysema (27%). Only 50% of patients underwent imaging before treatment, most often a neck CT (27%). 59% of patients needed surgery, with 6 patients (27%) requiring a tracheotomy. Two of them died (9%) and 6 suffered permanent complications. Conclusions: Cervical injuries involving ENT structures are rare in our environment, with the most common cause being traffic accidents. It is important to have standardised guidelines for the management of these patients, because they can often developed severe complications or even die if not treated properly very rapidly (AU)
