Purpose:
This study aimed to compare the outcomes of endoscopic tympanoplasty with post-conchal perichondrium (PCP) and microscopic tympanoplasty with temporalis fascia in repairing large-sized eardrum perforations.
Methods:
We performed a retrospective chart review of 43 patients who underwent type 1 tympanoplasty for simple large-sized perforations. The patients were divided into two groups: Group I (endoscopic ear surgery with a PCP graft, 22 patients) and Group II (microscopic ear surgery with temporalis fascia, 21 patients). Graft success rate, demographic data, pre- and postoperative pure-tone average and word-recognition score, closure of the air - bone gap, and postoperative pain scale scores were compared between the two groups.
Results:
The graft success rates in groups I and II were 86.3% and 85.7%, respectively. The mean operation time in Group I (79.8 ± 16.5 min) was significantly shorter than that in Group II (99.9 ± 26.7 min) (p = 0.006). Both groups showed significant improvements in the pure-tone average and word-recognition scores. Average closure of the air - bone gap (ABG) in groups I and II was 20.7 ± 6.9 dB and 17.6 ± 8.4 dB, respectively. The reduction in ABG in Group I had a significantly higher magnitude than in Group II at 1000 and 2000 Hz, respectively (p = 0.028 and p = 0.017). The two groups showed no significant difference in postoperative pain scores.
Conclusion:
Endoscopic tympanoplasty with PCP showed a reliable, fascia-preserved, and excellent outcome in repairing large-sized perforations.
