Clinical evaluation of steroid ointment for the treatment of mucoceles.

OBJECTIVE: We examined whether steroid ointment (0.1% dexamethasone) is an effective treatment for mucoceles. STUDY DESIGN: Using a retrospective cohort study design, a statistical study was conducted of 91 patients diagnosed with mucoceles at the Department of Dental and Oral Surgery, Saga University Hospital, Saga, Japan, between January 2006 and December 2016. The patients' age and sex; shape, size, and site of the lesion; duration; and treatment response rate were evaluated. RESULTS: The most frequent site of mucoceles was the lower labial mucosa, and several were <10 mm in size. The age of onset was often <20 years, with no sex-based differences. The treatment response rate was 65.8% for steroid ointment and 100% for surgical removal. In the subgroup analysis according to each clinical factor, some subgroups showed statistically nonsignificant differences compared with the surgery group. Among them, the older age and short disease duration subgroups showed small risk differences, suggesting that application of ointment may lead to a response in these subgroups. CONCLUSIONS: Although its response rate was lower than that of surgical removal, topical steroid application is a noninvasive and useful treatment method that can be used for patients in whom surgical treatment is infeasible.
