A long term follow up of conchal flap meatoplasty in chronic otitis externa

Abstract

A long-standing diffuse chronic otitis externa can lead to itching. Resultant scratching may then lead to irreversible skin changes with canal stenosis by scar tissue. The poor ventilation and increased humidity gives rise to bacterial and fungal growths leading to breakdown of the skin defences and worsening itching. This vicious itching–scratch cycle or downward spiral often fails to respond to medical treatment. For these cases a simple conchal flap meatoplasty may improve ventilation of the external auditory canal and may lead to a self cleaning ear. We reviewed 84 patients who had undergone conchal flap meatoplasty in Calderdale and Huddersfield NHS Trust Hospitals from April 1993 to June 2002. A long-term follow up of conchal flap meatoplasty in chronic otitis externa showed no records of complications or further otitis in 93.2 per cent of cases. Thus surgical intervention plays an important role in the treatment of otitis externa not responding to treatment.
