The efficacy of polidocanol sclerotherapy in mucocele of the minor salivary gland.

ABSTRACT

OBJECTIVES: Mucocele of the minor salivary gland is usually caused when the duct is injured, mucus leaks into the tissue space and the mucous gland are obstructed, which lead to cystic lesion formation and dilatation. Currently, there are multiple therapeutic methods available with various outcomes. This study aims to provide clinical evidence of polidocanol sclerotherapy for the treatment of mucocele of the minor salivary gland. METHODS: In this study, we injected polidocanol into 112 patients who were diagnosed with mucocele of the minor salivary gland and evaluated the treatment efficacy and safety systematically. RESULTS: Of the 122 cases, 102 cases were cured, eight cases showed remarkable remission, and two cases had partial remission. No recurrence was found during follow-up, and none of the cases showed an invalid effect, resulting in a total cure rate of 91.07%. No severe side effects were observed during treatment or the follow-up period. No significant difference in efficacy between different genders was found (P = 0.490). Polidocanol sclerotherapy for mucocele on the lower lip was more effective compared to mucocele on the inferior surface of the lingual apex (P = 0.035). CONCLUSION: Polidocanol sclerotherapy showed satisfying curative effects for mucocele of the minor salivary gland without causing side effects of anesthesia, trauma, or severe pain.
