Abstract
PURPOSE: Most traditional tympanoplasties require elevating the tympanic membrane (TM). These techniques are rather complicated and success rates are not perfect. Therefore, the authors developed a novel technique, transtympanic soft tissue (TST) tympanoplasty, which does not require raising eardrums, and evaluated its surgical efficiency compared to perichondrium underlay (PU) tympanoplasty. STUDY DESIGN: A retrospective study was conducted in a single center. METHODS: 152 cases who underwent TST tympanoplasty (n = 70) or PU tympanoplasty (n = 82) between 2011 and 2020 were included in the study. Perforation location, pure tone audiometry, complications, and closure rates were analyzed according to the size of the TM perforations: moderate perforation (25-40%, n = 100) and large perforation (≥ 40%, n = 52). RESULTS: For the moderate perforations, the closure rates of the TST (n = 45) and PU (n = 55) groups were 93.3% and 89.1%, respectively (p = 0.461), and even for the large perforations, the success rates were 88.0% in the TST group (n = 25) and 81.5% in the PU group (n = 27) (p = 0.515). The mean postoperative air-bone gap (ABG) values of the TST group for moderate and large perforations were 5.3 ± 5.8 dB and 6.6 ± 5.7 dB, respectively. There was no significant difference in postoperative ABG between the two surgical procedures (p > 0.05). The total operation time for TST tympanoplasty was significantly shorter than that for PU tympanoplasty (p = 0.002). CONCLUSIONS: TST tympanoplasty is considered a novel, simple technique to replace traditional tympanoplasty techniques involving raising eardrums, even for large-sized perforations.
