Extensive vascular malformation in the face treated by sclerotherapy with 5% ethanolamine oleate foam

The approach to vascular malformations in the face is a challenging step for professionals involved in the treatment of these anomalies. The objective is to describe a rare case of extensive vascular malformation in the face in an adult patient who had previously undergone several unsuccessful treatments during childhood and adolescence.A 46‐year‐old female patient reported an aesthetic discomfort in her face due to an increase in the volume of the upper lip and recurrent spontaneous bleeding in the oral cavity. On oral clinical evaluation, a blue‐purple colour, firm consistency on palpation, extension into the oral cavity, and moderate mobility of the incisors in the right hemimaxilla were observed. Angiography, magnetic resonance imaging and cone beam computed tomography were performed to verify the lesion's anatomical limits and hemodynamic properties. Four injections of sclerotherapy with an injection of 5% monoethanolamine oleate foam were performed.A significant reduction in the extent of vascular malformation was noted. At the moment, the patient had 3 years of follow‐up. She is extremely satisfied with the aesthetic result, and has had no episode of spontaneous bleeding or other complications.The request for new imaging exams allowed the characterization and precise delimitation of the vascular malformation, guiding the use of a minimally invasive technique using the injection of monoethanolamine oleate foam, providing an effective and satisfactory result for the patient.
