As with any invasive surgical procedure, there is a certain amount of associated risk and complication. Some important complications surrounding any operative procedures utilizing general anesthesia include bleeding, respiratory decompensation, infection, and relapse. Outcome and prognosis of Lefort procedures depend on many factors before, during, and after surgery. Major anatomical complications reported with Lefort I osteotomy include nasal septum deviation, ophthalmic and lacrimal duct injury, malocclusion or mal-union of the maxilla, and injury to stenson’s duct. A reciprocating saw is generally utilized to perform the osteotomy with sufficient cooling methods to reduce heat damage to the underlying bone. Overheating puts bony structures at risk of osteonecrosis. Separation of the nasal septum is crucial and care should be taken to avoid the nasotracheal tube on the side of nasal intubation. Sectioning the tube would compromise the patient’s airway and cause significant risk to the procedure. Separation of the pterygoid plate from the maxillary tuberosity is another technique sensitive step during final completion of the osteotomy in the region of the infratemporal fossa (Patel). Vasculature has a major influence on the success of treatment and bleeding is a common surgical complication. The maxillary artery is a major branch of the external carotid artery passing through the infratemporal fossa, coursing around the lateral pterygoid muscle and supplying soft tissue
