ABSTRACT: Acoustic reflex is a sensitive indicator of middle ear lesions when the tympanic membrane is in-tact and tympanometry is normal. Acoustic reflex is not usually observed in conductive hearing loss caused by disruption of the ossicular chain including ossicular discontinuity and fixation. Ossicular disruption can show at least partially intact acoustic reflex under a certain condition. Moreover, ossicular discontinuity with a nearly intact acoustic reflex is quite rare and there have been few reports published to date. We here present a rare case of conductive hearing loss with a nearly intact acoustic reflex, and the patient was surgically confirmed to have ossicular discontinuity.
