Symposium: contraindications to tympanoplasty. IV. Contraindications to tympanoplasty.

Aural and non-aural disorders that are relative or are absolute contraindications to tympanoplasty surgery are discussed. Particular attention is focused on non-aural convert general medical conditions that may escape the otologist's attention as he is not daily concerned in the management of such conditions. The aural contra-indications are dealt with briefly because of the obvious and well known disorders that are familiar to all otologists.
