Otosclerosis often occurs as a unilateral mixed or conductive hearing loss. In the absence of retrocochlear findings, otologists usually do not pursue further diagnostic testing. A patient who presented to the Warren Otologic Group with a unilateral mixed hearing loss is discussed. He was followed for 1 year with the intent of scheduling a stapedectomy. Two weeks prior to the surgical date, the patient developed a sudden hearing loss and was admitted to the hospital for treatment. Magnetic resonance imaging demonstrated a tiny, enhancing mass in the lateral internal auditory canal, measuring 7 mm in diameter. At surgery, the tumor was found to originate at the union of the nervus intermedius and the facial nerve. The simultaneous occurrence of facial nerve neuroma and otosclerosis is discussed, with emphasis on a thorough evaluation of all unilateral mixed hearing losses, including those attributable to otosclerosis.
