Abstract
OBJECTIVE: This study aims to compare the results of temporal muscle fascia and cartilage graft tympanoplasty operations in patients with subtotal tympanic membrane perforations.
METHODS: Between October 2011 and April 2013, a total of 67 patients (42 females, 25 males; mean age 30.1 years; range, 12 to 49 years) who underwent tympanoplasty due to inactive chronic otitis media and who had subtotal tympanic membrane perforation were included in this study. The patients were randomly divided into two groups as the cartilage graft group (CGG, n=33) and the fascia graft group (FGG, n=34). The mean air thresholds and mean air-bone gap (ABG) at 500, 1,000, and 2,000 Hz were measured by pure tone audiometry. Successful engraftment ratios and hearing outcomes were compared between the groups.
RESULTS: The duration of follow-up was 12 months. The mean preoperative pure tone hearing threshold (PTHT) in CGG and FGG were 48.9 dB and 45.88 dB, respectively. The mean preoperative ABG in CGG and FGG were 29.03 dB and 30.94 dB, respectively. The mean postoperative pure tone hearing gain in CGG and FGG were 8.96 dB and 10.5 dB, respectively. The mean postoperative ABG in CGG and FGG were 6.45 dB and 9.11 dB, respectively. There was no significant difference between the two techniques in terms of the ABG and pure tone average scores (p=0.51-0.155). Successful engraftment ratio in CGG and FGG were 96.9% (32/33) and 82.3% (28/34), respectively.
CONCLUSION: Although successful engraftment ratio in CGG is higher than FGG in broad tympanic membrane perforations, both techniques yield similar hearing outcomes.
