Management of retraction pockets of the pars tensa in children by excision and ventilation tube insertion.
Retraction pockets of the pars tensa in children can result in erosion of the ossicles leading to hearing loss and eventually cholesteatoma formation. Several different types of treatment for the more severe grades of retraction pocket have been described. The aim of this pilot study was to assess the outcome following simple excision and ventilation tube insertion of grade II, III and IV retraction pockets of the pars tensa. The eardrums were graded according to Sadé's classification (1979). There were seven grade II and four grade III retractions. Ten eardrums healed completely in a mean time of 3.6 months (mean follow-up 16 months) and there was one residual perforation. Two retractions recurred and both of these were only grade I. Clinically, an improvement in hearing was reported in seven children (eight ears) and the average air conduction threshold gain for these patients was 16 dB. A larger prospective study is currently underway.
