Huge Oro-antral communication defect: Buccal Fat Pad Grafting & Harvesting| Sinus Closure Stepwise

An oroantral communication (OAC) is an unnatural opening between the oral cavity (mouth) and the maxillary sinus (the air-filled cavity in the upper jaw). It most commonly results from dental extractions, particularly of upper back teeth, due to the close anatomical relationship between the tooth roots and the sinus floor. If untreated, an OAC can lead to complications like maxillary sinusitis or progress into a chronic oroantral fistula (OAF). Treatment depends on the size of the opening and may involve simple techniques for small openings or surgical closure with local flaps for larger ones. This patient was facing this complain from a few months . The chronic congestion of the maxillary sinus and Oro-Antral communication repair was managed by Department of Otorhinolaryngologist and Department of Maxillofacial surgery . The BFP as an anatomic element was first mentioned by Heister in 1732 and was described by Bichat in 1802 . The BFP is an anatomically rounded and biconvex structure that is of great importance in the facial contour. It is an adipose tissue surrounded by a thin capsule and located inside both masticatory spaces in the oromaxillofacial region. The BFP has a central body with four extensions: pterygopalatine temporal pterygoid buccal The central body and buccal extension account for approximately 50 % of the BFP and are the most clinically significant portions. The BFP has a 10-mL volume and a thickness of 6 mm and an approximate weight of 9.3 g . The BFP is surrounded by a thin fibrous capsule. Blood supply is provided by the vestibular and deep branches of the maxillary artery, the transverse facial branches of the superficial temporal artery and branches of the facial artery. The rich blood supply may explain the high success rate. It also may be one reason for the quick epithelialization of the fat. The BFP is a mass of specialized fatty tissue called syssarcosis, a fat that enhances muscular motion. It is distinct from the subcutaneous fat and shows marked similarity to the orbital fat. It can easily cover small to medium sized defects of about 4 cm in diameter. When properly dissected and mobilized the BFP provides 7 × 4 × 3 cm of a pedicled graft.
