“…Cholesteatoma-induced fistulas most commonly involve the horizontal semicircular canal (HSC). 1 After the HSC, the superior canal, posterior canal, and rarely the cochlea can be affected. 1 The incidence of cholesteatoma in adults is reported to be 9.2 per 100 000 per year, while 2.7% to 12% of these cases eventually lead to the occurrence of a labyrinthine fistula.…”

Horizontal canal fistulas are not uncommon in patients with cholesteatoma. Patients with canal wall down cavities and exposed horizontal canal fistulas develop significant dizziness with wind or suction exposure. Obliteration of mastoid cavities in patients with exposed fistulas can be challenging. We describe a patient with horizontal canal fistula and chronic dizziness from wind exposure who underwent successful mastoid cavity obliteration with preservation of hearing. Patients with horizontal canal fistulas in a canal wall down cavity can be managed with mastoid obliteration for relief of dizziness.

Cerebellar abscess is a reported complication of chronic suppurative otitis media (CSOM) and is life threatening at times. It usually develops by direct spread of CSOM through the bony erosion in the petrous bone or by thrombophlebitis of the sigmoid sinus. However, an alternative pathway of infection transmission from the petrous bone to the cerebellum through the anatomical bridge of the cranial nerves has possibly not been described before. A 63-year-old female patient with CSOM and cholesteatoma developed ataxia and right facial palsy. Computed tomography (CT) showed bone erosion of the right petrous bone suggesting middle ear infection. Post-contrast MRI revealed an enhancement of swollen 7th/8th nerve complex, suggesting neuritis, and cholesteatoma in the right petrous bone. It also showed ring enhancing lesion in the cerebellar peduncle of the same side suggesting brain abscess. Surgical intervention was performed emergently and pus aspirated. She also underwent mastoidectomy and removal of cholesteatoma later by the otolaryngology team and finally got better. This case illustrates that CSOM can cause cerebellar abscess by spreading infection via anatomical bridge of the cranial nerves without direct invasion from the temporal bone or thrombophlebitis of sinus.
