SCLEROTHERAPY FOR EXTENSIVE VASCULAR MALFORMATION IN THE TONGUE: A REPORT OF TWO CASES

Abstract

Vascular anomalies such as hemangioma, vascular malformations, and varix are common in the head and neck. Vascular malformations (VMs) are benign lesions of blood vessels originating from an error in vascular morphogenesis during the embryologic phase. Treatment depends on the location and extent of the lesion; sclerotherapy, surgical excision, and laser therapy are the most frequently performed. The objective of this work is to report 2 cases of extensive vascular malformation in the oral cavity treated with sclerotherapy. After diagnosis and shared decision making, the treatment consisted of 12 applications of monoethanolamine oleate (Ethamolin) in a 1:1 proportion with lidocaine anesthetic in the amount of 1.0 mL. Total regression of both lesions was achieved and the patients have been followed up with satisfactory results. This report shows that sclerotherapy is an effective and practical form of treatment for VMs, even in cases of extensive lesions.
