Management of attic retraction pockets.

Abstract

Attic retraction pockets, classified by degree of invasion and erosion, are reconstructed here as outlined by attic retraction pocket grade. Attic retraction pocket grade, surgical management, subsequent conditions of tympanic membrane and middle ear, and improvement of air-bone gap pure tone average were recorded. Our management strategy, based on attic retraction pocket grade, was applied to 200 ears: 44 grade I ears had non-surgical management and 156 grade II-V ears had surgical management. All 200 ears were followed up for 36-240 months, showing only 1 attic retraction pocket reformation and 1 adhesive otitis media (complication rate of 1 per cent), and improved air-bone gaps (p < 0.05). An earlier series of 50 grade IV attic retraction pockets used atticotomy with epitympanic reconstruction. These showed attic retraction pocket recurrence or cholesteatoma onset in 34 ears (68 per cent). When these ears were revised per protocol, there was no evidence of cholesteatoma thereafter. Reconstruction of the ossicles and scutal defect according to attic retraction pocket grade shows long-term stability of the tympanic membrane, middle ear and hearing.
