[Results of tympanoplasty with antrum exclusion in the treatment of middle ear cholesteatoma].
BACKGROUND
Exclusion of the antrum was designed to avoid the problem of mastoid ventilation by means of insufficient eustachian tube.


METHODS
We retrospectively reviewed 72 ears with cholesteatoma who underwent antrum exclusion tympanoplasty (57% in men, mean age 40.9 years). Mean follow-up was 31.2 months (range, 12-64 mo).


RESULTS
Exclusively epitympanic-antral cholesteatoma location (28.4%), and the necrosis of the long branch of the incus (54%) were the most common. The most used material to reconstruct the ossicular chain was Torp prosthesis (73.6%), followed by incus autograft (11.1%). We reported the following complications: postoperatory otorrhea (5.5%), perforation of neotympanum (16.7%), prosthesis extrusion (23.6%, time average of 15.6 months), and recurrence of cholesteatoma (4.2%).


CONCLUSIONS
The technique with antrum exclusion has reported acceptable results in the control cholesteatoma recidivism. Although the functional results are similar to those of the open techniques, the resulting cavity with the antroexclusion is more anatomic.
