Double-Peak tympanometry in keratosis obturans

Azliana Aziz, Mohd Khairi Md Daud

Indian Journal of Otology 2018 24(2):117-119

Tympanometry is an effective objective tool used to identify problems in the middle ear. Keratosis obturans (KO) is a rare condition but may cause bony erosion and gradual expansion of the bony external auditory canal (EAC). We report a case of 32-year-old woman with KO who presented with bilateral hearing loss for a few years and right ear pain and discharge for 3 months before visit to an otorhinolaryngology clinic. She was treated by ear drops antibiotic and repeated ear toilet. Tympanometry done revealed a large EAC volume with a double-peak admittance. Double-peak tympanometry with an intact tympanic membrane may indicate diseases causing severe erosion in the EAC.
