    Abstract:
    PURPOSE: To analyze the operative benefit of preoperative sclerotherapy of facial venous malformations and assess long-term patient outcome. MATERIALS AND METHODS: Preoperative sclerotherapy was performed in 24 consecutive patients referred before resection of facial venous malformation. Pretreatment imaging was reviewed for malformation dimensions (length, width, and height), and volumes were estimated. Sclerotherapy was performed with 3% sodium tetradecyl in the first 15 patients and 98% dehydrated alcohol in the remaining 9 patients. Operative blood loss, operative time, transfusion requirement, and hospital stay were recorded. Operative time per lesion volume and operative blood loss per lesion volume were calculated. Results were compared with 15 historical control patients who underwent resection of facial venous malformations without preoperative sclerotherapy. Long-term follow-up of study and control patients was performed. RESULTS: Compared with controls, patients undergoing preoperative venous sclerotherapy were significantly older (P = .0206) and had larger lesions in all three dimensions (height, P = .0002; length, P = .0010; width, P = .0004). Patients receiving sclerotherapy had shorter operative time per lesion volume (P < .0001) and reduced blood loss per lesion volume (P < .0001). Neither hospital stay nor the need for blood transfusion differed from the control patients (P = .2449 and P = .6857). Mild periprocedural complications were encountered in 12.5% of cases, and nerve paresis occurred in 8.3% of cases. Long-term follow-up revealed retreatment was required in 2 of 24 patients (8.3%). CONCLUSIONS: Preoperative sclerotherapy of venous malformations was associated with less operative time per lesion volume and less operative blood loss per lesion volume. Long-term follow-up revealed a low need for retreatment.
