Abstract
ObjectiveThe objective of this study was to compare the operation time, graft success, audiometric outcomes and complications of over-under technique using a temporalis fascia (TMF) and cartilage grafts for the repair of large perforations. Study designRandomized controlled trial. Materials and methods80 large perforations >2 quadrants of eardrum were prospectively randomized to undergo TMF over-under technique group (TFON, n = 40) or cartilage-perichondrium over-under technique group (CPON, n = 40). The graft success rate, audiometric outcomes, and complications were compared among two groups at 12 months. ResultsThe mean operation time was 56.8 ± 4.2 (range:52–71) min in the TFON group and 37.9 ± 2.8 (range: 31–47) min in the CPON group (P < 0.001). The lost follow-up rate was 3 (7.5 %) patients in the TFON group and 2 (5.0 %) patient in the CPON group (P = 0.644). Finally, 37 patients in the TFON group and 38 patients in the CPON group were included in this study. The graft infection rate was 2 (5.4 %) patients in the TFON group and 2 (5.3 %) patient in the CPON group (P = 0.626), all the graft infection resulted in the residual perforation. The remaining residual perforation was 2 (5.4 %) patients in the TFON group and 1 (2.6 %) patient in the CPON group; the re-perforation was 3 (8.1 %) patients in the TFON group and 0 (0.0 %) patient in the CPON group. The graft success rate was 81.1 % (30/37) patients in the TFON group and 92.1 % (35/38) patient in the CPON group. The mean preoperative and 12-month postoperative ABGs were significantly different in any group (P < 0.01). However, there were no significant difference among two groups regardless of pre-or post-ABGs or ABG closure. No lateralization of the graft or blunting was noted in any group. Four (10.8 %)patients developed atelectasis and one (2.7 %) developed the EAC scarring in the TFON group. Graft cholesteatomas was found in 2 (5.4 %) patients in the TFON group and in 5 (13.2 %) patients in the CPON group (P = 0.449). Three (8.1 %) patients had temporary hypogeusia in the TFON group. ConclusionAlthough temporalis fascia graft over-under technique obtained similar graft success rates and hearing outcomes for large chronic perforations to the cartilage-perichondrium over-under technique, temporalis fascia graft technique prolonged the operation time and increased the re-perforation and graft atelectasis. Nevertheless, the graft cholesteatomas were comparable among two techniques.
