The Role of Accurate Diagnosis of The Aesthetic Parameters of The Face in Preoperative Planning and Successful Surgical Treatment for Patients with Asymmetric Jaw Deformities

Аннотация

Facial asymmetry is a complex condition that affects both aesthetics and function, often requiring a multidisciplinary approach for accurate diagnosis and successful surgical correction. This study focuses on the role of precise diagnostic methods in preoperative planning and surgical treatment of patients with asymmetric jaw deformities. A total of 87 patients with skeletal malocclusions were examined, of whom 28 had asymmetric jaw deformities. The etiology of facial asymmetry is multifactorial, involving genetic, congenital, developmental, and environmental influences. Proper differentiation between true and false asymmetry is crucial for treatment planning. Diagnostic imaging, including 3D CBCT analysis, cephalometry, and facial photometry, plays a key role in establishing the skeletal and dental midline, evaluating condylar position, and determining asymmetry severity. This study highlights the importance of integrating advanced imaging techniques with 3D surgical planning for precise treatment strategies. The findings emphasize the necessity of individualized preoperative assessment to achieve optimal facial symmetry and functional outcomes.
