Introducción: la osteonecrosis del canal auditivo externo (OCAE) es una complicación esquelética infrecuente y poco conocida del tratamiento con antirresortivos. Caso clínico: presentamos el caso de una mujer de 57 años con osteoporosis, tratada durante cuatro años con alendronato, que fue remitida al otorrinolaringólogo para la extracción de un tapón de cerumen en el oído izquierdo. En la otoscopia se evidenciaron zonas ulceradas e indoloras en el suelo de ambos conductos auditivos externos, compatibles con osteonecrosis. Discusión: a pesar de que la OCAE es una complicación esquelética poco común por el uso de antirresortivos, el desarrollo de síntomas localizados en el oído debe alertar a los médicos sobre esta rara entidad clínica, que deben solicitar una valoración otorrinolaringológica que permita realizar un diagnóstico y un tratamiento precoces.
Introduction: osteonecrosis of the external auditory canal (OEAC) is a rare and poorly recognized skeletal complication of antiresorptive therapy. Case report: we present the case of a 57-year-old woman with osteoporosis on a 4-year regimen with alendronate. She was referred to an otolaryngologist for the removal of a cerumen plug in her left ear. Otoscopy revealed ulcerated and painless regions on the floor of both external auditory canals, which were consistent with osteonecrosis. Discussion: although OEAC is an uncommon skeletal complication of antiresorptive use, the development of localized ear symptoms should alert physicians on this rare clinical entity, prompting them to request an otolaryngological evaluation for early diagnosis and treatment.
