Abstract

OBJECTIVE:

For tympanoplasty, the most common grafting materials are the temporalis fascia or perichondrium; however, both require incision of the canal skin, which carries a risk of morbidity and the need for postoperative care. Inlay butterfly cartilage tympanoplasty, by which the perforation edges are refreshed and a cartilage is inserted through the perforation without canal incision, makes the graft easy, and reduces operating and recovery time. We analyze the outcome of inlay butterfly cartilage tympanoplasty.

MATERIALS AND METHODS:

This study included 112 patients who underwent tympanoplasty from January 2011 to August 2012. Patients were divided into 2 groups: patients who underwent inlay butterfly cartilage tympanoplasty (Group I, n = 56) and patients who underwent conventional underlay tympanoplasty using the temporalis fascia (Group II, n = 56). Anatomic success was defined as an intact, repaired tympanic membrane, and functional success was defined as a significant decrease in the air-bone gap at the end of follow-up. Perioperative pain was analyzed using a visual analogue scale (VAS). Surgical success, functional success, perioperative pain, and operating time were evaluated and compared.

RESULTS:

The surgical success rate was 96.4% in Group I and 91.1% in Group II (p = 0.435). The mean air-bone gap decrease was 7.9 ± 2.2 dB in Group I and 8.9 ± 3.2 dB in Group II (p = 0.426). Group I showed a lower VAS score for pain (1.5 ± 1.2) and a shorter operation time (25.6 ± 8.5 min) compared with those of Group II (4.9 ± 1.7, 48.6 ± 19.5 min, respectively) (p < 0.01).

CONCLUSION:

Inlay butterfly cartilage tympanoplasty is compatible with the conventional underlay technique in both anatomic and functional success rates. Its simplicity, shorter operation time, and rapid recovery time could make it an attractive surgical option.
