Abstract
INTRODUCTION: Arteriovenous malformations (AVMs) of facial bones are rare conditions. These lesions can cause aesthetic challenges, pain, impact on gums and teeth, facial asymmetry, and life-threatening bleeding. PRESENTATION OF THE CASE: This report described a case involving the resection of AVMs within the maxilla following preoperative embolization and sclerotherapy by using an ultrasonic bone aspirator (Sonopet®, Stryker, Kalamazoo, MI, USA) and a radiofrequency bipolar sealer (Aquamantys™, Medtronic, Minneapolis, MN, USA). The AVMs and deformed bone were resected en bloc through repeated cutting and hemostasis, preserving the maxillary crown and maintaining the maxillary structure by treating only the affected bone. DISCUSSION: Reducing inflow during surgery and controlling intraoperative bleeding requires thorough planning. Preoperative embolization and sclerotherapy can reduce inflow to the tumor, and appropriate surgical devices enable the resection of arteriovenous malformations within the maxilla. CONCLUSION: The method presented in this report is a viable treatment option because it allows for selective bone removal, thus leading to the preservation of crowns and maxillary contour.
