Traditional approaches that decrease intraoperative bleeding into the surgical field include vessel preservation using multiple bony windows or neutralizing the vessel at the surgical site. Unfortunately, these methods are technique sensitive, time intensive, and may lead to hemosinus and graft loss. The variable distance from the crest of the alveolar ridge and vessel diameter further complicates pre-operative planning. This paper discusses the anatomical features of the alveolar antral artery, techniques for clinical assessment, and current management strategies. We then describe a novel protocol to manage the alveolar antral artery in sinus lift procedures via tamponade of the vessel at a proximal site. This method is faster than those described in the literature, does not require any additional equipment or expertise, and aims to improve long-term graft predictability by decreasing the risk of sinus membrane perforation. The alveolar antral artery is an under-reported source of surgical complications and warrants further research.展开更多
