A Rare Case of Odontogenic Chronic Suppurative Otitis Media.

Common causes of chronic suppurative otitis media (CSOM) include persistence of acute otitis media, cholesteatoma, and eustachian tube dysfunction. We describe a patient who presented with CSOM of several years duration refractory to medical management. Ultimately, a dental abscess was found on computed tomography (CT) to be the source of concurrent ipsilateral maxillary sinusitis and mastoiditis. Extraction of the molar abscess resulted in complete resolution of her CSOM and need to be on antibiotics. To our knowledge, this is the first report of an odontogenic cause of chronic suppurative otitis media.
