Abstract
Mucocele of the anterior lingual salivary glands is a more common cystic lesion, especially in patients aged less than 20 years. The study is aimed to observe the effect of treatment by injection of absolute ethanol instead of surgery. Fourteen outpatients diagnosed as mucocele of the glands of Blandin-Nuhn were selected. These patients, after blood investigation, were treated by injection of absolute ethanol into a mucous cavity of lesion under superficial anesthesia with 2% lidocaine once a week and followed up from 3 months to 2 years. Mucocele of the glands of Blandin-Nuhn was extirpated in all patients after 1 to 3 injections. There were no other complications except slight distending pain occurred on the same day when the patients were treated. The recurrence was not observed during the follow-up period. In conclusion, the study suggests that injection of absolute ethanol may be an alternative means for treating mucocele of the glands of Blandin-Nuhn, because it is mininvasive, safe, effective, economic, and simply manipulated compared with surgical treatment.
