Abstract
Purpose
To assess the anatomical and functional outcomes of endoscopic transcanal tympanoplasty type I for tympanic membrane perforations.
Methods
Eight hundred thirty-five patients who underwent tympanoplasty between January 2011 and January 2019 were selected. Patients with tympanic membrane perforation treated with a transcanal endoscopic tympanoplasty type 1 and a follow-up period longer than 6 months have been retrospectively reviewed. The presence of cholesteatoma or ossicular chain dysfunctions were considered exclusion criteria. Eighty-one patients were included in the present study population. The main outcome was the rate of overall graft success. Secondary outcomes included hearing results. Prognostic factors related to both the abovementioned outcomes were assessed.
Results
Overall, 66 patients (81.5%) had a successful graft at the last follow-up evaluation. Mean follow-up was 22.1 (range 6–104) months. The anterior quadrants were entailed by the perforation in 62 (76.5%) cases. The overall success rate with cartilage (or cartilage and perichondrium) was 91.2% (p < 0.01). The median preoperative and postoperative ABG were 18.7 (13.4–25.6) and 7.5 (2.5–12.5), respectively, revealing a significant median improvement of 11.2 (p < 0.001). The type of graft and the postoperative tympanic membrane status were significantly associated with the audiologic outcome with p = 0.01 and p = 0.02, respectively.
Conclusions
Endoscopic tympanoplasty type I is a reliable technique with reasonable anatomic and audiologic results. Tympanic membrane grafting with cartilage (or cartilage and perichondrium) guarantees a higher rate of perforation closure and satisfactory hearing results. Anterior eardrum perforations can be successfully and safely managed with transcanal endoscopic approach avoiding postauricular approach and canalplasty.
