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)

La audición en la enfermedad ósea de Paget / Hearing in Paget's disease of bone

Introducción y objetivos: La enfermedad ósea de Paget (EOP) puede cursar con hipoacusia. Con el objetivo de cuantificar, caracterizar y determinar los factores de riesgo de hipoacusia en un grupo de pacientes con EOP se realiza el presente estudio. Métodos: Se realizó un estudio observacional, transversal del tipo casos y controles que incluyó una cohorte de 76 sujetos con diagnóstico de EOP en el grupo caso y un grupo control de 134 sujetos. Se analiza la información clínica, demográfica y audiométrica de los sujetos incluidos. Resultados: El análisis comparativo entre el grupo de sujetos con EOP y el grupo control determinó que el grupo caso presentaba un umbral medio auditivo mayor (39,51dB) que el grupo control (37,28 dB) (p = 0,069) y que presentaba hipoacusia transmisiva con mayor frecuencia (22,76%) que el grupo control (12,05%) (p = 0,0062). El análisis de los factores de riesgo de hipoacusia determinó que la afectación craneal en la gammagrafía ósea, la edad y la HTA, entre otros, constituían factores de riesgo de mayor pérdida auditiva en la EOP. Conclusiones: Los sujetos con EOP presentaron una pérdida auditiva más severa y con mayor frecuencia de tipo transmisivo que el grupo control. Los sujetos con afectación de la calota craneal por EOP presentaron mayor pérdida auditiva que los sujetos sin afectación craneal. La afectación de la calota craneal por la EOP y la edad constituyeron factores de riesgo de hipoacusia

Introduction and objectives: Paget's disease of bone (PDB) may lead to hearing loss. The present study was conducted with the aim of measuring, characterizing and determining the risk factors for hearing loss in a group of subjects with PDB. Methods: An observational, transversal, case-control study was conducted, a cohort of 76 subjects diagnosed with PDB in the case group and a control group of 134 subjects were included. Clinical, demographic and audiometric data were analysed. Results: The comparative analysis between the subjects in the PDB group and the control group found that the case group showed higher hearing thresholds (39,51 dB) compared with the control group (37.28 dB) (P=.069) and presented a greater rate of conductive hearing loss (22.76%) than the control group (12.05%) (P=.0062). The study of risk factors for hearing loss found that skull involvement in bone scintigraphy, age and high blood pressure were risk factors for higher impairment in PDB. Conclusions: The subjects with PDB showed more profound and a higher proportion of conductive hearing loss than the control group. The patients with PDB and skull involvement presented a more severe hearing loss compared with the subjects without skull involvement. Skull involvement and age were found to be risk factors for hearing loss
