Abstract

Background and Objectives Granular myringitis is troublesome for otologist because uncertain etiology and often been overlooked due to vague clinical symptoms and signs. The ideal treatment is elusive. Our study was to investigate the clinical characteristics of granular myringitis and analyzing the effect of the two different strategies, including carbon dioxide laser (CO2 laser) and caustic agent cauterization to manage granular myringitis. Study Design: Retrospective review Subjects and Methods One hundred and thirty patients with granular myringitis receiving treatment at a single medical center from July 2009 to January 2018 were enrolled. We retrospectively reviewed the charts and surgical records. The main two different strategies to manage focal refractory granular myringitis were analyzed, including carbon dioxide laser and caustic solution. We also recorded the clinical course and determine which strategy is better. Results One hundred and thirty patients with granular myringitis were enrolled. 47/130 (36.1%) had previous otologic procedures. Frequent ototrrhea is the most common symptom (66.1%). Posterior-inferior quadrant is the most common site of involvement (58%). The successful rate of CO2 laser, caustic agent were 94.9% and 79.2%. The recurrence rate was comparable between CO2 laser and caustic agent. No major complication was found in either individual group. Conclusion: Otologic procedure may be a predisposing factor of focal chronic myringitis. Ear drops had poor efficacy compared to other treatments. It can be apply only on minor and fresh symptom cases. In this study, we suggest CO2 laser can be the first line treatment, especially for the troublesome or refractory GM cases, which had the higher successful rate and less complication comparing to caustic agent cauterization.
