Stapedectomy in residency training

The number of new patients with otosclerosis seen by the average otolaryngologist has declined over the past several years. As a result, a controversy has arisen regarding the ability to train residents adequately in the technique of stapedectomy. In this regard, we have analyzed 44 consecutive stapedectomies performed by senior residents, under direct faculty supervision, at the University of California, San Francisco. All procedures were total stapedectomies, performed under local anesthesia, utilizing either wire-vein or wire-perichondrium technique. Four of the ears required footplate or promontory drilling. Closure to within 10 dB of the preoperative bone conduction, averaged over the speech frequencies of 500, 1000, and 2000 Hz, was achieved in 75% of ears, and closure to within 20 dB in 93% of ears. In no patient was hearing made worse. While there were no permanent complications, self-limited problems occurred in 9% of the procedures. Despite a declining caseload of otosclerotic ears in residency programs, it is possible to train residents safely in stapes surgery, given a program of consistent technique and close faculty supervision.
