RESUMEN
Abstract 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).
