Sclerotherapy of benign oral vascular lesions with non-diluted ethanolamine oleate / Escleroterapia de lesiones vasculares orales benignas con oleato de etanolamina no diluido

Benign oral vascular lesions are anomalies characterized by the blood vessels proliferation or malformation and the treatment with the sclerosing agent ethanolamine oleate acts irrigating the vessel producing a sterile inflammatory response. The objective of this study was to report and discuss the results from treatment of benign oral vascular lesions with non-diluted ethanolamine oleate through the analysis of clinical records. The sample was composed by the selection of twenty-six patients (12 male and 14 female), with oral vascular malformations. All lesions were treated with intralesional injections of undiluted ethanolamine oleate. These patients attended in Oral Medicine outpatient clinic of the Federal University of Paraná between the years of 2011 to 2015. The average age was 60.65 years, with a higher prevalence for women. The majority of the individuals had one lesion and its location was mostly in the lower lip. The main complaint was about a physical discomfort. The lesions had the average size of 6.52 mm and received a median number of 2.32 applications. Only one patient reported feeling pain in the postoperative week. In most cases the resolution of the lesion was considered partial. Follow-up was obtained up to one month after the end of treatment. The sclerotherapy with undiluted ethanolamine oleate shows acceptable results in the treatment of small benign oral vascular lesions with a few minor side effects.

Las lesiones vasculares orales benignas son anomalías caracterizadas por la proliferación o malformación de los vasos sanguíneos y el tratamiento con el agente esclerosante etanolamina oleato actúa irrigando el vaso produciendo una respuesta inflamatoria estéril. El objetivo de este estudio fue informar y discutir los resultados del tratamiento de lesiones vasculares orales benignas con oleato de etanolamina no diluido a través del análisis de historias clínicas. La muestra estuvo compuesta por la selección de veintiséis pacientes (12 hombres y 14 mujeres), con malformaciones vasculares orales. Todas las lesiones fueron tratadas con inyecciones intralesionales de oleato de etanolamina sin diluir. Estos pacientes acudieron a la clínica ambulatoria de Medicina Oral de la Universidad Federal de Paraná entre los años 2011 a 2015. La edad promedio fue de 60,65 años, con una mayor prevalencia para las mujeres. La mayoría de los individuos tenían una lesión y su ubicación era principalmente en el labio inferior. La queja principal era sobre una molestia física. Las lesiones tenían un tamaño promedio de 6,52 mm y recibieron una mediana de 2,32 aplicaciones. Solo un paciente informó haber sentido dolor en la semana postoperatoria. En la mayoría de los casos, la resolución de la lesión se consideró parcial. El seguimiento se obtuvo hasta un mes después del final del tratamiento. La escleroterapia con oleato de etanolamina sin diluir muestra resultados aceptables en el tratamiento de pequeñas lesiones vasculares orales benignas con algunos efectos secundarios menores.

Sclerotherapy as an esthetic indication in oral vascular malformations: a case series

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).
