Perilymph fistulae.
A small series of 14 post-stapedectomy fistulae illustrates the varied aetiology. The long-term competence of the oval window seal may be ensured by making a small hole in the footplate. Contraction of ageing fibrous tissue contributes to late stapedectomy failures. Long-term follow-up is important, for any deterioration in hearing after stapedectomy may result from a perilymph leak.
