| Popis: | Introduction:Chronic obliterative otitis externa is a rare cause of conductive hearing loss, characterised by stenosis of the deep ear canal secondary to chronic inflammation. A multitude of canalplasty techniques have been described, with variable success.Method:Fourteen patients undergoing canalplasty performed by the senior author for refractory obliterative otitis externa, over an 8-year period, were included in the study. All underwent split-skin grafting of the denuded canal and meticulous post-operative aural care. Outcome measures included the Glasgow Benefit Inventory and pure tone audiology.Results:At 3 months post-operatively, the four-tone average threshold had improved by a mean of 13.9 dB (95 per cent confidence interval –9.9 to 37.8 dB; t Conclusion:Significant improvements in both hearing and quality of life are achievable in patients with end-stage obliterative otitis externa treated surgically. Highly trained and competent aural care practitioners are a prerequisite for the success of the procedure, and a substantial number of patients must be prepared to submit to long-term follow-up care. |
