Otomycosis with Perforated Tympanic Membrane: Self medication with Topical Antifungal Solution versus Medicated Ear Wick
Abstract
Objectives: In otomycosis with tympanic membrane perforation, many physicians prefer to insert an ear wick medicated with antimycotic cream. This needs multiple visits to the clinic and keeps the ear blocked for several days. Direct instillation of alcohol based antimycotic solution causes severe burning if it reaches the middle ear. In this work we compare patient’s self medication with clotrimazole antimycotic solution used on Q-tips with physician–inserted ear wicks; in terms of safety, efficacy and patient satisfaction.
Study Design & Setting: Prospective controlled study in ambulatory setting.
Methodology: Forty consecutive patients with otomycosis with tympanic membrane perforation were included in the study. Diagnosis of otomycosis was both clinical and with mycological culture. Mean pure tone average (PTA) in the involved ear was measured after cleaning fungal debris. Patients were then, randomized into two groups; Q-tip group patients (n=20) were taught to self-medicate their ears two times daily with the clotrimazole solution on suitable Q-tips for three weeks. In ear wick group (n=20), a gauze wick impregnated with clotrimazole cream was inserted in the ear. Wick was changed every third day for two more visits (one week overall). Patients were followed up for 3 months.
Results: After three weeks all patients in Q-tip group and ear wick group had relief of their ear itching and complete disappearance of fungal growth in the deep meatus and on the tympanic membrane. PTA was 22+11dB in Q-tip group and 25 +. 12 dB in ear wick group; the difference was not statistically significant (p= 0.11). Patients in ear wick group had sense of ear blocking and wetness during period of treatment. Transient burning sensation was reported by 2 patients in Q-tip group. During three months, there was recurrence of otomycosis in 5 patients from ear wick group and no recurrence in Q-tip group (p=0.04).
Conclusion: Self medication with clotrimazole solution on Q-tips and physician inserted medicated wicks are equally safe in treating otomycosis with perforated tympanic membrane. However, self medication with antimycotic solution on Q-tips gives more patient satisfaction and less rate of otomycosis recurrence.
