Bivalve cartilage inlay myringoplasty: an office-based procedure for closing small to medium-sized tympanic membrane perforations.

OBJECTIVE

To determine whether bivalve inlay cartilage-perichondrium myringoplasty (BCM) is successful in closing tympanic membrane perforations in an office setting.

STUDY

DESIGN

Retrospective case review.

SUBJECTS AND

METHODS

Adult patients with chronic perforations underwent BCM under local and topical anesthesia. Success was defined as complete closure of perforation at follow-up of at least 1 month. Predictors of success were identified by comparing the success and failure groups on pre- and postoperative pure tone average (PTA), patient demographics (age, gender), and characteristics of the perforations (size, location, duration, etiology).

RESULTS

A total of 145 procedures were performed and the patients were followed for 1 to 78 months. The success rate for perforations smaller than 4 mm was 75 percent. Size of the perforation, and pre- and postoperative PTAs were significantly different between the two groups. The only significant predictors of success were preoperative PTA and size of perforation.

CONCLUSIONS

BCM is a viable option for closure of small and medium-sized perforations in an office setting.
