- W2956452960 abstract "Objective Tympanic membrane perforations must be closed with surgery; however, most surgical procedures are considerably invasive in nature. The aim of this study was to evaluate the outcomes of minimally invasive myringoplasty using platelet-rich plasma (PRP) and an atelocollagen sponge for closure of chronic tympanic membrane perforations, as well as to identify the factors affecting the surgical outcome. Methods The records of 118 patients who underwent surgical closure of chronic tympanic membrane perforation at an ear–nose–throat clinic were reviewed retrospectively. After removing the margin of the perforation via a transcanal approach under local anesthesia, an atelocollagen sponge injected with PRP was inserted into the perforation as a scaffold. If the size of the perforation decreased after the surgery, the same surgical procedure was repeated. The success rate of closure after the last surgery was evaluated in terms of the size of the perforation. In addition, the relationships of the success rate with the cause and duration of perforation and patient age were also examined. Results The perforation was closed after initial or repeat surgeries in 95.8% (68/71) of cases with small-sized perforations, 80.0% (32/40) of cases with middle-sized perforations, and 85.7% (6/7) of cases with large-sized perforations. Multiple surgeries (up to four times) were required for middle- and large-sized perforations, and even for some small-sized perforations. The number of re-operations required for closure significantly increased with increase in the size of the perforation (Kruskal–Wallis test, p < 0.01). The cause and duration of perforation were not predictors of the surgical outcome. However, patient age was a significant predictor of the surgical outcome; patients older than 80 years had a significantly worse success rate than younger patients (Fisher’s exact test, p < 0.01). Conclusion Minimally invasive myringoplasty using PRP has a satisfactory success rate even for large-sized tympanic membrane perforations. PRP is autologous and its use is non-toxic and safe. Although informed consent from the patient is necessary for the repetition of the surgery and for patients older than 80 years, this technique appears to be a promising office-based procedure for closure of chronic tympanic membrane perforations." @default.
