- Abstract: OBJECTIVES: To compare the short- and long-term hearing outcomes after successful inlay cartilage tympanoplasty between patients with small (< or =25%) and large (> or =50%) eardrums perforations. METHODS: This is a retrospective case series study conducted in a tertiary referral center. Twenty-five patients who underwent 27 procedures were enrolled. Their mean age was 60.26 years (range, 42 to 76 years). The mean follow-up time was 18.86 months (range, 12.30 to 35.83 months). The preoperative, initial postoperative, and long-term hearing results in patients with total repair of the eardrum were analyzed. RESULTS: In the small size group, the average (+/-standard deviation) air-bone gap (ABG) closure was 1.08+/-7.53 dB in the short-term and 2.33+/-11.56 dB in the long-term hearing examinations. There was no difference between short- and long-term ABG closure (P=0.689). In the large size group, the average ABG closure was 9.77+/-9.40 dB in the short-term and 16.25+/-6.01 dB in the long-term hearing examinations. There was a significant difference between short- and long-term ABG closure (P=0.029). CONCLUSION: Patients with large perforations have continuous hearing improvement and ABG closure for more than one year. In contrast, the short- and long-term postoperative ABGs are almost the same in patients with small perforations. More long-term postoperative follow-up of hearing results is necessary for large perforations.
