Objective:
The objective of this study was to evaluate the graft outcome and complications of endoscopic perichondrium-cartilage button technique for repairing chronic large perforations in teenagers.
Study Design:
Prospective case series.
Materials And Methods:
56 patients with chronic large perforations more than 50% of the TM who underwent endoscopic perichondrium-cartilage button technique. The graft success rate, hearing outcome, and complications were evaluated at postoperative 3, 6 and 12 months.
Results:
Of the 56 ears, 3 (5.4%) patients lost follow-up, 53 (94.6%) patients were finally included in this study. The mean operation time was 37.2 ± 5.4 min. The retrograde tympanomeatal flap elevation was performed in 16 (30.2%) patients. The graft success rate was 96.2% (51/53) at postoperative 3 months and 94.3% (50/53) at postoperative 12 months. The mean preoperative ABG was 25.0 ± 3.7 dB, while the mean postoperative ABG postoperatively 6 months was 12.8 ± 3.1 dB; the difference between these values was significant. No graft-related complications (e.g., graft lateralization, significant blunting, and graft medialization) were encountered during the follow-up period. However, graft keratin pearl was noticed in 5.7% (3/53) patients, which occurred in the handle of malleus in 2 and antero-inferior margin in one. All the graft pearls were endoscopically removed in the outpatient setting.
Conclusions:
Endoscopic perichondrium-cartilage button technique can be achieved in every teenager patient with chronic large perforation without cholesteatoma, and, is a safe and efficient procedure.
