Arterial supply of maxillary sinus and potential for bleeding complication during lateral approach sinus elevation.

摘要: There are 3 arteries that supply the maxillary sinus (i.e., posterior superior alveolar, infraorbital, and lateral nasal arteries), any of which may be encountered during approach elevation surgery. These ultimate branches artery. Although it has not been reported, there is a theoretical potential for severing an intraosseously located artery vigorous curettage lining in medial wall sinus. Techniques cessation bleeding discussed, such as electrocautery endoscopic ligation. Head can significantly decrease blood flow to area.
