Objective: To investigate the efficacy of sclerotherapy with monoethanolamine oleate (MEO) in a series of cases of benign oral vascular lesions (BOVL).
Material and methods: Clinical records and images were retrieved (2015-2019), and data regarding age, gender, location, size, symptomatology, treatment and outcomes of patients were collected. All patients were diagnosed according to the classification of International Society for the Study of Vascular Anomalies and received the same treatment protocol (MEO 0.05 g/mL). The collected data were submitted to descriptive analysis and Pearson's chi-square test (p ≤ 0.05).
Results: Thirty-seven patients were treated. Most were female (70.3%) aged 9 to 88 years (median, 57.5 ± 17.4 years). Lower lip (54.1%) was the most affected site followed by buccal mucosa (16.2%). Thirty-two lesions were asymptomatic and 35.1% showed ≤ 0.5 cm in size. In 48.6% of the patients, only one application of MEO was performed. Complete regression occurred in 62.2% of cases, whereas 27% showed partial regression. One patient showed hypersensitivity during treatment. There was no significant difference between clinical outcome and age, anatomic site, size, and number of applications of MEO.
Conclusions: Sclerotherapy with MEO is an acceptable and affordable treatment and can provide satisfactory results in BOVL, especially where other treatment options could compromise the esthetic aspects.
Clinical relevance: As it is a non-invasive therapy leading, in most cases, to adequate clinical results, safety, and tolerability, sclerotherapy with MEO can be considered an effective treatment for BOVL.
