ABSTRACT
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). 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.
