[Evaluation of the clinical efficacy of 3% polydocaol in the treatment of low-flow oral mucosal venous malformation].

PURPOSE: To investigate the clinical efficacy of 3% polidocanol in the treatment of low-flow venous malformations of the oral mucosa.

METHODS

A total of 62 patients with low-flow venous malformations of the oral mucosa admitted to the Department of Oral and Maxillofacial Surgery, Affiliated Stomatological Hospital of China Medical University from January to December 2024 were selected. All patients were treated with 3% polidocanol foam sclerotherapy and followed up for 1 to 12 months. The therapeutic effects were evaluated through grade assessment, subjective evaluation by patients, and comparison of photos before and after treatment.

RESULTS

Among the 62 patients, 52 were cured (83.87%), 8 showed remarkbally improved, and 2 were improved, with a total effective rate of 100%. The number of treatments ranged from 1 to 3 times, with an average of 1.4 times. Visual analogue scale(VAS) of pain showed that immediate postoperative pain score was 3-8 points, which decreased to 0-1 points after 1 month. Adverse reactions occurred in 8 patients postoperatively, all of them returned to normal after 1 month.

CONCLUSIONS

3% polidocanol is a safe, effective, and low-side-effect treatment for venous malformations of the oral mucosa.
