PURPOSE: This study evaluated the efficacy of short-term danazol prophylaxis in hereditary angioedema patients undergoing maxillofacial or dental procedures.
PATIENTS AND METHODS: Twelve patients with a history of edema after dental procedures were administered danazol (600 mg/d) 4 days preoperatively and 4 days postoperatively. The serum levels of complement components were determined preoperatively and postoperatively as well as at 6, 12 and 24 hours in six patients.
RESULTS: None of the 12 patients developed angioneurotic edema. The serum levels of the complement components were decreased immediately after surgery and returned to normal within 24 hours.
CONCLUSION: The short-term prophylactic use of danazol in patients with hereditary angioedema undergoing oral surgery is an effective preventive measure.
