Abstract
The treatment dilemmas and our institutional experience with head and neck hemangiomas and vascular malformations are reviewed. Fifty-eight patients (38 with hemangiomas, 20 with vascular malformations) aged from newborn to 78 years were treated from 1975 to 1993. Eighty-seven percent of patients provided up-to-date follow-up, yielding a median follow-up interval of 7.18 years from intervention. Only significantly sized tumors (minimum diameter > 4 cm) were studied. Sodium tetradecyl sulfate sclerotherapy (SDS) was a sole therapy in 12 patients (all with hemangiomas) and was used in combination with surgical ablation in 22 patients (16 with hemangiomas, 6 with vascular malformations). The minority of tumors from both categories were completely removed with ablative surgery (six hemangiomas [23%], eight vascular malformations [44%]). Significantly debilitating tumor postsurgical recurrence, which led to mortality in some patients, was unique to vascular malformations with high flow on the basis of increased arterial to venous shunting. Less alarming but significant functional and cosmetic challenges are created in primarily postadolescent patients with incompletely involuted hemangiomas and low-flow vascular malformations of the head and neck. We have had a favorable experience with the combined application of sclerotherapy and conservative ablative surgery in this group. Patient survey implied satisfaction with treatment in the majority: Nine indicated they benefited significantly (17%); 37 indicated they were generally improved (71%); and 6 stated they did not benefit (12%). Tumor-specific philosophy on ablative therapy, recurrence patterns, and associated complications are presented.
