6.30.24 Quick Review #163 - #surgery #surgeon #doctorgallagher #oralsurgery #oralsurgeon #omfs #dentist #dentistry #dental #lefort #orthognathic The LeFort I osteotomy is a common surgical procedure in orthognathic surgery, primarily used to correct maxillary deformities. Important anatomical landmarks for a LeFort I osteotomy include: 1. Piriform Aperture: The bony opening of the nasal cavity. The osteotomy line typically extends lateral to the piriform aperture. 2. Zygomaticomaxillary Buttress: The region where the maxilla and zygoma meet. Osteotomy cuts are made through or near this buttress. 3. Nasal Floor: The base of the nasal cavity. The osteotomy line passes just above the nasal floor. 4. Infraorbital Foramen: Contains the infraorbital nerve. The osteotomy is planned to avoid damaging this nerve to prevent sensory disturbances. 5. Anterior Nasal Spine: A reference point for the midline and positioning during surgery. 6. Pterygomaxillary Junction: The area where the pterygoid plates meet the maxilla. This region requires careful disjunction to mobilize the maxilla effectively. References: 1. AO Foundation. (n.d.).
