Modified Bondy technique.

Bondy operation is a type of modified radical mastoidectomy in which the mastoid cavity is exteriorized without disturbing the intact ossicular chain and pars tensa. It is indicated in cases of epitympanic cholesteatoma with intact ossicular chain, normal pars tensa, and good hearing. The advantages of the technique are one-stage surgery with preservation of preoperative hearing levels, which is not possible with any other procedure. This article presents the indications, technique, results, and complications.
