Obliteration of the Cavity in Mastoidectomy

Abstract

A modification of Rambo's teniporal-musculoplasty for obliterating tlie cavity following mastoidectomy is described and the early and late operative results in 110 cases of active, chronic otitis are presented. The use of retro-auricular tissue together with the temporal muscle gives a long, cranially pedicled flap, one end of which is placed into the antruni and tlie other towards the tip of the mastoid process. To avoid stenosis, tlie skin of the auditory canal and of tlie external meatus is incised longitudinally. By this method more than 90% of tlie ears dried, and there were only a few postoperative coniplications. The late results showed tliat tlie ears remained dry and that there was no recurrence cliolesteatonia or of infection. The results in respect to hearing are briefly mentioned.
