Background:
The use of monoethanolamine oleate 5% is effective for the treatment of vascular malformations with low blood flow.
Objectives:
To report a case series of vascular malformations in the mouth and oral cavity treated with monoethanolamine oleate 5%.
Methods:
A retrospective descriptive study was performed in electronic patient charts covering seven years. Patient demographics, diagnostic resources, lesion site, size, and number of applications of monoethanolamine oleate 5% were collected.
Results:
A total of 21 vascular malformations were recorded, located mostly on the lower lip (52.3%) and resolved in a single application in 14 patients. The authors found 19 patients treated with sclerotherapy. Thirteen were women and six were men, with a mean age of 61 years.
Study Limitation:
Small sample size.
Conclusions:
Sclerotherapy is an effective treatment for vascular malformations of the lips and oral cavity, with resolution after only one or two applications (n=16).
