This study shows as decisive factors the history of tympanostomy tube insertion and surgical approach. The closure of the perforation observed at the 6th post-operative month is almost definitive, without finding significant differences ahead. The myringoplasty can be performed simultaneously in bilateral perforations and in a day-case basis with same success rates. Astatistically significant audiometric improvement area is described, after myringoplasty, undescribed previously in literature.
The aim of this study was to evaluate prognostic factors in surgical outcome and hearing threshold after myringoplasty, in pediatric age.
A 10-year retrospective review of 142 myringoplasties performed by a single surgeon of the Pediatric ENT Department of 12 de Octubre University Hospital. Multiple prognostic factors were investigated, such as those related to perforation and surgery, contralateral ear status, and pre- and post-operative hearing threshold.
The overall rate of closure of the perforation was 74.64%. The re-perforation rate was directly proportional to the number of tympanostomy tube insertion (OR = 1.64). Other determining factors were the surgical approach, the graft position and side. There was a post-operative significant improvement (p < 0.001) insuring that the more affected frequencies, low (125-500 Hz) and high frequencies (4000-8000 Hz), were the more improved after the procedure.
本研究表明鼓膜置管史和手术方式是决定性因素。术后第6个月观察到的穿孔闭合几乎是确定的，之后未发现显著差异。鼓膜成形术可同时用于双侧穿孔，且可在日间手术基础上进行，成功率相同。本研究描述了鼓膜成形术后听力改善的统计学显著区域，这在之前的文献中未曾描述。
本研究旨在评估小儿鼓膜成形术后手术结果和听力阈值的预后因素。
对12 de Octubre大学医院儿科耳鼻喉科一名外科医生进行的142例鼓膜成形术进行了10年的回顾性研究。研究了多个预后因素，如与穿孔和手术相关的因素、对侧耳状况以及术前和术后听力阈值。
穿孔闭合的总体率为74.64%。再穿孔率与鼓膜置管次数成正比（比值比=1.64）。其他决定性因素是手术方式、移植物位置和侧别。术后有显著改善（p<0.001），确保了受影响更大的频率，即低频（125 - 500Hz）和高频（4000 - 8000Hz），在手术后改善得更多。
