The senior author's 8-year personal experience with biocompatible ossicular implants is reviewed. Four hundred sixty-one consecutive operations, in which high-density polyethylene sponge ossicular replacement prostheses were used, are grouped according to the Bellucci classification of chronic otitis media. The prostheses used were the drum-to-footplate prosthesis (TORP, total) and the drum-to-stapes prosthesis (PORP, partial)*. Each group's short- and long-term hearing results are compared. Prosthesis extrusion and persistent or recurrent conductive hearing loss are the most common causes of operation failure. Failures within each group are analyzed, and techniques to prevent these complications are outlined.

In spite of modern diagnostic and surgical techniques, the results of congenital ear malformation surgery are often disappointing. Not only are hearing results less than expected, but also postoperative canal stenosis is a significant problem. This paper reviews the historical development of atresia surgery, the various classification systems, and the management of congenital ear malformations at The Otology Group. The authors' surgical technique is described and the postoperative results of 33 ear operations are discussed. Twenty-two of 33 cases showed some improvement in hearing. Postoperative stenosis occurred in 42% of atresia cases.

OBJECTIVES: Two steps in stapedotomy are particularly challenging: (1) micropick fenestration of the stapes footplate (SF) and (2) crimping of the stapes prosthesis (SP) to the incus. We conducted trials to determine if experience correlates with differences in performance for these tasks. METHODS: In a surgical model of stapedotomy, performance was measured for 3 experienced and 3 novice surgeons. For fenestration, we measured ability to target the fenestration and force applied to the SF. For crimping, we measured crimp quality, movement of the SP during crimping, and force applied to the SF. RESULTS: Experienced surgeons demonstrated significantly better ability to target the fenestration and, during crimping, caused less SP movement and a significantly lower rate of SP dislodgment. CONCLUSIONS: Clear differences in task performance are measurable between more and less experienced surgeons during critical steps of stapedotomy. CLINICAL SIGNIFICANCE: The observed differences in task performance may contribute to an understanding of maneuvers that increase the risk of inadequate prosthesis placement and cochlear trauma—factors likely responsible for variable hearing results with strapedotomy.

OBJECTIVE: To review hearing results after implantation of a self-crimping stapes prosthesis. STUDY DESIGN AND SETTING: Analysis of hearing results in patients implanted with a self-crimping stapes prosthesis at two academic hospitals from 2000 to 2004. RESULTS: Seventy-nine ears were divided into short-term and intermediate follow-up groups. The mean postoperative air-bone gap (ABG), preoperative minus postoperative ABG, and preoperative minus postoperative bone conduction values were 5.7, 21.4, and 4.1 dB, respectively, for the short-term group, and 6.3, 22.3, and 4.7dB, respectively, for the intermediate group. The ABG was <10 dB in 88 percent of the short-term group and in 79 percent of the intermediate group. CONCLUSIONS: The self-crimping Nitinol stapes prosthesis provides excellent short-term and intermediate postoperative hearing results, and may overcome the limitations of stapes prostheses requiring manual crimping. SIGNIFICANCE: This paper provides evidence for the use of a self-crimping Nitinol stapes prosthesis, which may simplify hearing restoration surgery for stapes fixation.

Introduction: Surgical treatment of patients with far-advanced otosclerosis (FAO) has not yet been standardized. Patients with FAO are the candidates for stapes surgery or cochlear implant (CI). Although many surgeons consider stapes surgery as the first choice, other authors prefer CI because of the excellent hearing results. Objective: The authors discuss their experience in the treatment of patients with FAO, potentially candidates for CI, who underwent stapedotomy. Materials and Methods: Eleven adult patients with FAO underwent stapedotomy from 2006 to 2016. Pure-tone average (PTA) between 0.5-1-2-3 kHz and speech perception test with hearing aids were determined before and after stapedotomy. Results: The results show a statistically significant improvement in air condition threshold (PTA) and satisfactory results with regard to speech recognition in 9 (81.8%) cases. Postoperative results are not influenced by the type of stapedotomy prosthesis employed and do not change during follow-up (3 years). Conclusions: The authors suggest first performing stapes surgery in patients with FAO and reserving CI in case of failure.
