RESUMO

Introducción: La otoesclerosis es un padecimiento que ocasiona hipoacusia y es de relativa frecuencia en nuestra región con tratamiento quirúrgico bien establecido e índice de éxito relativamente alto. Objetivo: Determinar el índice de éxito del tratamiento quirúrgico de la otoesclerosis en un tercer nivel de atención. Diseño: Estudio observacional descriptivo de corte transversal. Materiales y Métodos. Se revisaron los expedientes clínicos de los pacientes con diagnóstico de otoesclerosis y manejo quirúrgico con estapedectomía y estapedotomía en el servicio de otorrinolaringología de esta institución de julio 2009 a enero 2011. Resultados: De un total de 56 expedientes revisados en el período de estudio, se encontraron 36 expedientes completos, 61.9% mujeres y 27.1% hombres, con una edad media de 36.7 años; la afección bilateral fue del 80% y unilateral del 20%. Con respecto al síntoma predominante, 62% de los pacientes presentaron sólo hipoacusia y 38% tinitus e hipoacusia, con una duración media de 8.4 años. Los hallazgos audiológicos demostraron una prevalencia de hipoacusia conductiva moderada bilateral en 13 pacientes, severa bilateral en 4 casos, hipoacusia conductiva superficial unilateral en 2, hipoacusia conductiva severa y moderada unilateral con uno en ambos casos e hipoacusia conductiva unilateral superficial en 1. En 21 pacientes, se realizaron 29 cirugías, bilaterales en 10 pacientes, 7 en oído izquierdo y 2 en oído derecho y 2 decidieron no operar. Discusión: Se encontró un índice de éxito quirúrgico mayor del 90%. Conclusión: Los resultados presentados, fueron semejantes a los reportados en la literatura.


Introduction: Otosclerosis is a relatively frequent condition that causes hearing loss in our region. The surgical treatment is well established with stapedectomy and stapedotomy, and its success rate is high. Objective: To determine the success rate of surgical treatment of otosclerosis in a third level of care. Design: Observational, Cross sectional study. Material and methods: We reviewed the clinical records of patients with diagnosis and surgical management with stapedectomy and stapedotomy in the otorhinolaryngology department of this institution from July 2009 to January 2011. Results: Of a total of 56 files reviewed during the study period, 36 complete files were found, 61.9% were female and 27.1% were male, with a mean age of 36.7 years, bilateral affection was found in 80% of the patients and unilateral in 20%. Regarding to the predominant symptom, 62% of the patients had only hearing loss and 38% reported tinnitus and hearing loss, with an average duration of 8.4 years. The audiological findings showed a prevalence of moderate bilateral conductive hearing loss in 13 cases, bilateral severe in 4 cases, unilateral conductive hearing loss in 2, unilateral moderate and severe conductive hearing loss in one case, and unilateral conductive hearing loss in 1. In 21 patients, 29 surgeries were carried out, bilateral in 10 patients, 7 in the left ear and 2 in the right ear and 2 decided not to operate.
