Abstract
Patients with petrous bone cholesteatoma most commonly present with hearing loss and facial paralysis. Other clinical presentations can include otorrhea, tinnitus, aural fullness, otalgia, and dizziness. Here, we report a patient with petrous bone cholesteatoma who presented with cerebrospinal fluid rhinorrhea. This patient was initially misdiagnosed with rhinogenic cerebrospinal fluid leakage, and was finally diagnosed with the supralabyrinthine type of petrous bone cholesteatoma. During the surgical repair through the transmastoid trans-superior semicircular canal approach, the fistula was found in the superior wall of the internal auditory canal. He had satisfactory outcomes after the surgery, with no recurrent cerebrospinal fluid rhinorrhea.
