title: Surgical treatment of obliterative otitis externa.
abstract: Seven patients with fibrous obliteration of the ear canal due to long-standing otitis externa were seen at St Mary's Hospital during the past 10 years. Two patients underwent bilateral surgery making a total of 9 ear cases. Two patients developed early restenosis within 6 months of permeatal excision of the fibrous core and skin grafting, and one patient had late stenosis 4 years following postaural excision, meatoplasty and skin grafting. Two of these patients opted for revision surgery and a total of 6 patients (8 ear cases) underwent postaural excision with Körner flap canalplasty, enlargement of the bony ear canal and skin grafting. The average hearing gain was 25 dB in the speech frequencies and only one restenosis was seen at 3 years. This was successfully revised. Radical excisional surgery with a wide bony canalplasty is recommended in this condition.
