Wound healing after multisegmental le fort i osteotomy and transection of the descending palatine vessels

Orthognathic Surgery in Cleft Lip and Palate Patients

“…This method, for instance, emphasizes preservation of the labial soft tissue mucosal pedicle in the maxillary of patients. The significance of this flap circulation that is achieved by considering biological principles was confirmed in the study by Bell et al that was carried out on Rhesus monkeys [38].…”

Anterior Palatal Fistula Formation after Le Fort I Osteotomy in Conventional Orthognathic Surgery

“…Maxillary blood flow was reduced by about 50% within 24 hours after Le Fort I osteotomy if the palatal descending arteries became ligated on both sides [ 12 ]. According to Dodson et al's study, it returns to normal after one week [ 13 , 14 ].…”

Computer-Assisted Microvascular Free Flap Reconstruction and Implant Rehabilitation of the Maxilla—Treatment of a Rare Post-orthognathic Complication

“…Although rare, cases of post-orthognathic avascular necrosis of partial or total maxilla continue to be reported in the literature periodically [1,8,9]. Due to sufficient collateral vascular perfusion of the maxilla via the ascending pharyngeal arteries, ascending palatine arteries, and rich network of alveolar branches of the internal maxillary artery, even after the ligation of the descending palatine arteries and/or multiple osteotomies [12,[14][15][16][17], the incidence of vascular compromise of the osteotomized segments remains extremely low (\ 1%). In 1990, Lanigan et al sent a questionnaire to 5000 oral and maxillofacial surgeons throughout North America and received 800 responses in which 36 cases were described to have some degree of avascular necrosis of the maxilla after a LeFort 1 osteotomy [4].…”
