Abstract: BACKGROUND/OBJECTIVE:Oral malformations of the tongue are exceedingly rare. The aim of this study was to evaluate the effectiveness of individualized treatment for patients with vascular malformations of the tongue. METHODS:This retrospective study is based on a consecutive local registry at a tertiary care Interdisciplinary Center for Vascular Anomalies. Patients with vascular malformations of the tongue were included. Indications for therapy of the vascular malformation were macroglossia with the impossibility to close the mouth, bleeding, recurrent infection and dysphagia. Size regression of the malformation (volume measurement) and symptom improvement were investigated. RESULTS:Out of 971 consecutive patients with vascular malformations, 16 patients suffered from a vascular malformation of the tongue. Twelve patients had slow-flow malformations and 4 fast-flow malformations. Indications for interventions were bleeding (4/16, 25%), macroglossia (6/16, 37.5%), and recurrent infections (4/16, 25%). For two patients (2/16, 12.5%), there was no indication for intervention due to absence of symptoms. Four patients received sclerotherapy, 7 patients Bleomycin-electrosclerotherapy (BEST) and 3 patients embolization. Median follow-up was 16 months (IQR 7–35.5). In all patients, symptoms had decreased after two interventions at a median (IQR 1–3.75). Volume reduction of the malformation of the tongue was 13.3% (from median 27.9 cm3 to median 24.2 cm3, p = 0.0039), and even more pronounced when considering only patients with BEST (from 86 cm3 to 59.1 cm3, p = 0.001). CONCLUSION:Symptoms of vascular malformations of the tongue are improved after a median of two interventions with significantly increased volume reduction after Bleomycin-electrosclerotherapy.
