Objectives
The aim of this study was to explore the method of adding a secondary perichondrium patch to enhance the primary cartilage–perichondrium patch during endoscopic myringoplasty and to evaluate the effectiveness of this method in terms of healing rate and post-operative hearing of patients with poor prognostic factors (eustachian tube dysfunction, large perforations, subtotal perforations, and anterior marginal perforations).
Design
This retrospective study analyzed a total of 80 patients (36 females and 44 males, median age of 40.55 years) who had received a secondary perichondrium patch during endoscopic cartilage myringoplasty. Patients were followed up for 6 months. Healing rates, complications, preoperative and postoperative pure-tone average (PTA) and air–bone gap (ABG) were analyzed.
Results
At 6-month follow-up, the healing rate of tympanic membrane was 97.5% (78/80). The mean pure-tone average (PTA) improved from 43.18 ± 14.57 dB HL pre-operatively to 27.08 ± 9.36 dB HL 6 months after the operation (P = 0.002). Similarly, the mean ABG improved from 19.05 ± 5.72 dB HL pre-operatively to 9.36 ± 3.75 dB HL (P = 0.0019) at 6 months after the operation. Major complications were not observed during follow-up.
Conclusions
The use of a secondary perichondrium patch during endoscopic cartilage myringoplasty for large, subtotal and marginal tympanic membrane perforations achieved a high healing rate and a statistically significant hearing gain with low incidence of complications.
