Promethazine hydrochloride injection in the sclerotherapy of oral mucocele

Preliminary experience with promethazine hydrochloride injection in the sclerotherapy of oral mucocele: In this study, we took advantage of the corrosiveness of promethazine hydrochloride injection, i.e., its chemical corrosiveness at the injection site, for sclerotherapy of mucocele1. In previous reports, the more serious complications may have been caused by perivascular extravasation or unintentional intra-arterial injection, which is a common feature of all chemical corrosive sclerosants2. Therefore, in the sclerotherapy procedure, we emphasized that it is necessary to puncture into the lesion and aspirate saliva with viscous wire drawing to ensure correct positioning, and then inject the drug into the lesion1.
