Objectives. The aim of this study was to evaluate and report the long-term results of the butterfly cartilage tympanoplasty. Short-term and long-term hearing outcomes were compared according to age and perforation location as well. Methods. Ninety-three patients who were diagnosed with noncomplicated chronic otitis media and underwent microscopic transcanal butterfly cartilage tympanoplasty due to anterior, posterior, and central tympanic membrane perforation were included. Age, gender, follow-up time, pre- and postoperative pure tone audiometry thresholds (both air and bone conduction), pre- and postoperative air-bone gaps (ABGs), if any residual perforation was noted. Results. At the end of the follow-up period, successful closure occurred in 88 of 93 patients and success rate is 94.6%. In all patients, including those with residual perforations, the mean preoperative bone conduction threshold was 15.9 dB (range, 5 to 50 dB) among all groups whereas mean air conduction threshold was 36.4±15.1 dB (range, 10 to 90 dB) preoperatively and 28.8±14.3 dB in 6th month follow-up and 24.9±14.1 dB 24th month follow-up. Preoperative mean ABG was 22.1±7.1 dB (range, 5 to 40 dB) whereas 13.3±5.9 dB 6 months after surgery and 11.9±5.5 dB 24 months after surgery. There was a significant difference between pre- and postoperative ABG in both 6th and 24th month follow-up (P6 mo–24 mo<0.05). Furthermore, preoperative mean air conduction differed significantly from postoperative 6th and 24th month follow-up mean air conduction thresholds (P<0.05). Conclusion. We suggested that butterfly cartilage tympanoplasty can be safely performed in small, moderate, and even large perforations, as the hearing outcomes and successful closure rate are similar to those of other surgical methods. Moreover, it can be performed under local anaesthesia and it has low complication rates.

Objectives. The aim of this prospective clinical study was to measure the audiologic outcomes of the patients that underwent endoscopic transcanal cartilage tympanoplasty, and to investigate the effects on cochlear function. Methods. Thirty-three patients (33 ears) who were diagnosed with noncomplicated chronic otitis media and underwent endoscopic transcanal cartilage tympanoplasty technique were included. Pre- and postoperative first month distortion product otoacoustic emission (DPOAE) signal-to-noise ratio (SNR), bone conduction hearing levels and air bone gap (ABG) values were measured and total endoscope usage time was noted. Results. Preoperative median SNR measurements at 0.5, 1, 2, and 4 kHz were 6 dB (1–11; interquartile range [IQR], 1), 6 dB (4–20; IQR, 1), 7 dB (3–26; IQR, 5) and 5.50 dB (0–9; IQR, 3), respectively. Postoperative median SNR measurements at 0.5, 1, 2, and 4 kHz were 6 dB (3–9; IQR, 1), 6 dB (2–21; IQR, 3), 7 dB (2–20; IQR, 3), and 6 dB (0–10; IQR, 7), respectively. Regarding the DPOAE measurements, there was no statistically significant difference between the SNR values of all given frequencies (P>0.05). Regarding the pure tone audiometry (PTA) measurements, bone conduction was significantly better at 0.5 and 1 kHz, postoperatively (P<0.05) and there was statistically significant difference at 2 and 4 kHz (P>0.05). Additionally, no statistically significant correlation was found between the SNR and PTA measurements and the endoscope usage time (P>0.05). Conclusion. We suggested that cochlear functions and sensorineural hearing remained stable after endoscopic transcanal cartilage tympanoplasty and cold light source doesn’t cause significant adverse effects cochlear functions.
