Subtotal petrosectomy with external canal overclosure in the management of chronic suppurative otitis media.
Subtotal petrosectomy with external canal overclosure has been used in the management of 10 patients with chronic suppurative otitis media in the past four years. These patients fall into two categories. One group consisted of patients with end-stage chronically discharging mastoid cavities, despite aggressive medical therapy. The other group comprised patients who had developed disabling peripheral vestibular symptoms and had a mastoid cavity from past surgery for chronic otitis media. In both groups the affected ear had absent or poor auditory function. In the second group, a translabyrinthine section of the vestibular and/or cochlear nerves was performed in conjunction with subtotal petrosectomy. The procedure has been very successful in relieving the persistent otorrhoea, giving the patient an ear without a cavity that would need regular care. No restriction on swimming and participation in other water sports is an additional advantage. Illustrative cases are used to discuss the technique and indications.
