Endoscopic "Push-Trough" Technique Cartilage Myringoplasty in Anterior Tympanic Membrane Perforations

Abstract

ObjectivesTo evaluate endoscopic push-through technique cartilage myringoplasty results.MethodsThis prospective study was performed on patients with anterior tympanic membrane perforations and endoscopic push-through technique cartilage myringoplasty was performed between 2011 and 2013. The patients who did not have any cholesteatoma or otorrhea in the previous 3 months, and had an air bone gap ≤25 dB in their preoperative audiograms were included in the study. They were followed up with endoscopic examination and audiograms at 2nd, 6th, 12th, and 24th postoperative months. Pure tone averages were calculated at 0.5, 1, 2, and 4 kHz frequencies.ResultsOf 32 patients, 19 were females and 13 were males. The mean age was 40.3 years (range, 16 to 62 years), and the mean follow-up period was 12.4 months (range, 6 to 24 months). Graft success rate was 87.5% in this study. Preoperative mean air conduction hearing threshold was 25.9 dB, and the mean air-bone gap was 11.9 dB while these values improved to 19.5 dB and 5.3 dB respectively in the postoperative period. The mean hearing gain was 6.4 dB. The analysis of preoperative and postoperative mean air conduction thresholds and air bone gap values of the patients revealed statistically significant differences.ConclusionUnderlay cartilage myringoplasty with endoscopic push-through technique in anterior quadrant tympanic membrane perforations is an effective, minimally invasive and feasible method.
