ABSTRACT Although ossiculoplasty, also known as ossicular chain reconstruction (OCR), was attempted initially in the early 1900s, it was not until the 1950s that it became commonplace and relatively well understood. Since then, there have been numerous technologic advances and a gain in the understanding of ossiculoplasty. However, successful OCR with resulting long-term stability can be a daunting task. Typically, the most common condition requiring revision OCR is chronic suppurative otitis media (COM) with or without cholesteatoma. Primary and revision OCR are performed also for blunt and penetrating trauma-induced conductive hearing loss, congenital defects (eg, atresia), and benign and malignant tumors. Typically, reconstruction in ears with COM is more difficult than in ears without infection. This article discusses the key factors involved in successful revision OCR.

    ABSTRACT: OBJECTIVE: To review the results of revision surgery for cholesteatoma. STUDY DESIGN: Retrospective review of patient's records. SETTING: Tertiary referral center. PATIENTS: A retrospective study of patients operated for acquired middle ear cholesteatoma during the period 1990-2002 was performed. A total of 758 patients were divided into two groups according to surgical experience, and followed during short-term and long-term period. The cholesteatoma was divided according to location, age of patients, status of auditory ossicles, and bilaterality of disease. INTERVENTIONS: The patients were treated with single canal wall up or wall down, according to the propagation of disease and condition of middle ear. The indications for the reoperations were: recurrent or residual cholesteatoma, resuppuration, and AB gap more than 20dB. MAIN OUTCOME MEASURES: Type of surgical therapy, localization of cholesteatoma, age of patients, revisions, bilaterality of disease, damage of auditory ossicles and learning curve were analyzed. RESULTS: The number of revision operations was reduced in the second period (from totally 24.3% to 16.4%). Closed technique gave a significantly lower rate of failure. For attic cholesteatoma, adults, bilateral disease, and ossicular damage the rate of revisions was significantly lower with surgical experience. CONCLUSION: Surgical experience was important for reduction of reoperation rate for attic and sinus cholesteatoma, adults, bilateral cholesteatoma, and when closed technique is used.

    ABSTRACT: Objective. Evaluate a porous polyethylene prosthesis with two-point stabilization in total ossiculoplasty. This approach utilizes a lateral as well as a medial graft to stabilize a total ossicular prosthesis (TOP). Study Design. Retrospective cohort review of total ossiculoplasty. Methods. All patients who underwent total ossiculoplasty during the years 2004-2007 were included in the study group. Only five patients (10%) had primary surgery whereas 45 (90%) underwent revision surgery. Cartilage grafts covering the prosthesis (Sheehy, Xomed) laterally were used in all patients with areolar tissue being used for medial stabilization at the stapes footplate. Follow-up examination and audiometrics were performed a mean of 8.1 months following surgery. Results. The percentage of patients closing their ABG to within 10 dB was 44% with 66% closing their ABG to within 20 dB. The mean four-frequency hearing gain was 15.7 dB. The mean postoperative ABG was 15.7 dB. Conclusion. Audiometric results following total ossiculoplasty surgery using two-point stabilization exceeded results from the otologic literature. Proper two-point fixation with areolar tissue and stabilization utilizing cartilage were the keys to achieving a relatively high percentage of success in chronic ear disease in this sample.
