Long-term observation after soft posterior meatal wall reconstruction in ears with cholesteatoma

Abstract

AbstractWe performed tympanoplasty with reconstruction of the soft posterior meatal wall for the prevention of post-operative retraction pocket formation. Our method is characterized by the reconstruction of the softposterior meatal wall, non-obliteration with permanent or temporary materials, including Gelfoam, no use of a Palva flap and the use of fibrin glue for attaching the fascia to the posterior meatal skin. None of the patients experienced post-operative narrow-neck retraction pocket formation, and whenever aeration of the middle ear was disturbed, a balloon-like retraction was observed. Not all the posterior meatal walls retracted. The final position of the posterior meatal wall varied among the subjects. No serious cavity or hearing problems have occurred since surgery. Due to the strong possibility of post-operative retraction pocket formation in cases with a large balloon-like retraction, we rejected adopting the canal wall up technique or hard posterior meatal wall reconstruction.
