Objective: To review the clinical features and management of patients diagnosed with granular myringitis at Siriraj Hospital, during 2014–2016, and their applications in clinical practice.Methods: The clinical data of 115 patients diagnosed with myringitis at the Department of Otorhinolaryngology, Faculty of Medicine Siriraj Hospital, between September 1, 2014, and September 30, 2016, were retrospectively reviewed. Patients who were lost to follow-up after the first visit or patients who were diagnosed with other diseases, such as bullous myringitis, were excluded, leaving 96 patients included in the study. Patient information and data, including age, gender, underlying disease, history of ear disease and surgery, symptoms, duration, type of treatment, outcome, total follow-up time, complications, and recurrence rate were recorded.Results: In total, 96 patients (27 men (28.10%) and 69 women (71.90%)) were included in the study. Their ages ranged from 3 to 90 years old (mean, 52.88). Sixty-two patients (64.60%) were diagnosed by otologic staff. The average duration of symptoms from onset was 5.6 months (range, 0.03–60.80 months). The most frequent symptom was otorrhea (55.3%). There were 38 treatment regimens applied. The most common medications used were topical antibiotics with steroids (28.11%), topical antibiotics (24.91%), and diluted vinegar (17.08%). There was no significant difference in the curative rate between these regimens (p = 0.261).Conclusion: Granular myringitis is a poorly understood condition and there is no standard treatment regimen. While there is a great variation in the treatment of granular myringitis at Siriraj Hospital, this retrospective review showed there was no statistical significant difference among the different regimens. Further high-value research is needed to further assess the management strategies.
Objective Granular myringitis is characterised by de-epithelialisation of the tympanic membrane. Patients present with intermittent otorrhoea, otalgia or itching. With improper or inadequate treatment, granular myringitis could cause ear canal fibrosis and stenosis. There are no standard topical ear drops for granular myringitis. Treatments have inconsistent success rates and variable timelines. This study aimed to compare the effectiveness of treating granular myringitis with 1 and 2 per cent acetic acid solutions for two weeks. Method This double-blind, randomised, controlled trial enrolled and randomly allocated 47 participants to 2 groups between October 2021 and June 2022. Results After two weeks, the groups’ treatment success rates did not differ significantly. There was a 10 per cent recurrence rate 8 weeks after treatment completion. All patients tolerated the diluted vinegar. Conclusion There is no difference in the efficacy of 1 and 2 per cent diluted vinegar in treating granular myringitis for two weeks.
