Inclusion criteria
Inclusion criteria: The subjects meeting the inclusion criteria were adult patients aged between 18 and 75 years. This is because child patients have special craniofacial anatomical structures and growth and development characteristics, while patients over 75 years old may have different bone quality conditions, which may affect the homogeneity of the study. Eligible patients include those who need to undergo elective maxillofacial surgery under general anesthesia, specifically including zygomatic-maxillary complex fractures, mandibular fractures requiring open reduction and internal fixation (ORIF), and patients undergoing non-traumatic/pathological surgeries such as ameloblastoma resection. The cases included in the study must meet the following criteria: 1. Suffering from maxillofacial fractures, confirmed by preoperative CT or cone-beam CT (CBCT) imaging, and requiring surgical treatment; Or other patients in oral and maxillofacial surgery who require intraoperative CT for auxiliary treatment. 2. The patient must have the cognitive ability to understand the relevant content of the study, give informed consent and agree to undergo follow-up assessment.
Exclusion criteria
Exclusion criteria: To maintain methodological rigor and ensure clinical applicability, the following exclusion criteria will be implemented: 1. Incomplete imaging or medical record data; 2. There has been a fracture in the affected maxillofacial area or surgical treatment has been received 3. Congenital or acquired facial deformities that may affect the assessment results 4. Pregnant or lactating women who have been ruled out due to radiation exposure risk 5. Patients who are unwilling or unable to provide informed consent, or who are unable to comply with imaging examination and follow-up procedures 6. If there are systemic diseases (such as diabetes, liver or kidney dysfunction) or local infections (such as sinusitis or osteomyelitis) that directly affect the quality or interpretation of intraoperative or postoperative images, or if they are clinically assessed by the attending surgeon as contraindications for surgery
