ABSTRACT
One of the most fearful complications of middle ear surgery is injury to facial nerve. Facial canal dehiscence leads to an increased risk of facial nerve damage even in routine middle ear procedures. We are reporting a very rare presentation of dehiscent vertical segment of facial canal found during myringoplasty which must be kept in mind while lifting the fibrocartilagenous tympanic annulus.
Key words: Facial canal dehiscence, Tympanic annulus
