    Abstract:
    We conducted an open-label study of 109 untreated patients who had excessive or impacted cerumen. Our goal was to evaluate the safety and efficacy of Sofenz Cerumenolytic Solution, a methyltrypsin-containing earwax removal solution. Each patient's external auditory canal was filled with Sofenz for 15 minutes. The primary measure of efficacy--visibility of the tympanic membrane--was assessed after the solution had been drained from the canal and again after the canal had been irrigated with lukewarm water. If the tympanic membrane was not completely visible following either application, the procedure was repeated. A safety examination was conducted 1 to 3 days after treatment. Secondary outcomes measures included relief of otologic symptoms (e.g., hearing loss, tinnitus, etc.) and patients'overall satisfaction with treatment. Immediately after treatment, we found that the external auditory canal was completely visible in 81 patients (74.3%) after 1 application of Sofenz and subsequent irrigation, and in 98 patients (89.9%) after 2 applications of each. At the safety follow-up visit, we determined that the number of otologic symptoms had declined by 93.2%. A self-reported assessment completed by each patient following the procedure revealed a high degree of satisfaction with treatment. A total of 58 adverse events were reported, but only 16 were directly related to treatment, and all were transient and either mild or moderate. We conclude that 1 or 2 applications of Sofenz followed by irrigation with lukewarm water is a safe, well-tolerated, and effective treatment for excessive or impacted cerumen in the external auditory canal.
