Selective angiographic studies prior to Le Fort I osteotomy in patients with cleft lip and palate

Postoperative Complications Following LeFort 1 Maxillary Advancement Surgery in Cleft Palate Patients

“…Orthognathic surgery in cleft patient's runs with an increased risk of ischemic complications due to scarring and reduced vascularity of the mucoperiosteal tissues from previous lip and palate surgery. A study by Drommer and Luhr identified smaller greater palatine arteries in cleft patients using angiography prior to orthognathic surgery (Drommer, 1979) . Considerations to surgical technique such as preservation of the palatine arteries, minimizing soft tissue trauma, and maintaining buccal pedicles can reduce such complications (Andersson et al, 2010).…”

Morphologic Evaluation for Safe Le Fort I Osteotomy in Cleft Lip and Palate

“…There are 2 main concerns regarding LFI osteotomy in patients with cleft lip and palate. First, it is necessary to consider whether blood flow can be established in the descending palatine artery, which is often narrowed as a result of primary surgeries (Drommer, 1979). Second, it is necessary to consider the abnormal fracture to the maxilla because of its complex form (Robinson and Hendy, 1986; Chung et al, 2014).…”
