Extra Perichondrium Patch to Enhance Cartilage Graft during Endoscopic
Cartilage Myringoplasty
Abstract
Abstract Objectives The aim of this study was to evaluate whether adding
an extra perichondrium patch to enhance the cartilage graft during
endoscopic myringoplasty can improve the healing rate and post-operative
hearing of patients with poor prognostic factors (eustachian tube
dysfunction, large perforations, subtotal perforations and marginal
perforations). Methods This retrospective study analyzed a total of 80
patients (40 females and 40 males, median age of 40.55 years) who had
received an extra patch during endoscopic cartilage myringoplasty.
Patients were followed up for six months. Healing rates, complications,
preoperative and postoperative pure-tone average (PTA) and air-bone gap
(ABG) were analyzed. Results At six months follow-up, the healing rate
of tympanic membrane was 100% (80/80). The mean preoperative pure-tone
average (PTA)(43.18± 14.57 dB HL)significantly decreased (27.08±9.36
dB HL) six months after the operation (P=0.002). Similarly, the mean
preoperative ABG(19.05±5.72 dB HL)reduced to(9.36±3.75 dB HL)
(P=0.0019) at sixth month. Major complications were not observed during
follow-up. Conclusions The usage of an extra 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.
