Intratumoral ligation in the management of orofacial cavernous haemangiomas.

After a short comment on the essential data concerning the pathology, clinical aspects and treatment of orofacial haemangiomas, the author presents his own method of treatment by intratumoral ligation. He describes the technical details by which interception of the blood supply to the haemangioma is achieved and also breakdown of the angiomatous mass into segments by the occlusion of vascular channels, thus completely interrupting the intratumoral blood flow. Obstruction of vascular lumina, endothelial atrophy, blood clot organization in the small diverticula between them and also subsequent fibrous hyperplasia which take the place of the vascular hyperplasia ensue. The method was used in 31 cases of cavernous haemangioma in different sites; the results, with follow-up periods of 1-8 years prove its efficacy.
