Abstract

This study analyzes short- and long-term results of 436 ossiculoplasties accomplished by a minor columella sculptured in the remnants of the incus and placed between the tympanic membrane and stapes head. Most cases were operated on by a transcanal approach through an ear speculum, under local anesthesia. Cases in which an associated mastoidectomy was performed to remove diseased tissue are excluded. The residual air-bone gap was < 20 dB in 86.1% of cases 2 months after surgery, in 77.0% 1 year later, and then remained stable over time, even in patients seen 5 to 15 years after the operation. Complications were rare. A total sensorineural hearing loss occurred in two cases (0.4%), the cause of which remained unexplained. Other complications included a high-frequency hearing loss in 10 (2.3%) cases, tinnitus in 12 (2.7%), and transitory vertigo in two (0.4%). We conclude that this type of ossiculoplasty is a simple but adequate procedure for primary restoration of hearing in chronic otitis media if the stapes is intact and mobile.
