ABSTRACT: Skeletal Class III malocclusions with mandibular asymmetry present significant diagnostic and therapeutic challenges due to their complex three-dimensional discrepancies. These conditions often result in both functional and aesthetic impairments, especially in adult patients where growth has ceased, limiting treatment options. Case Presentation: An 18-year-old female presented with mandibular prognathism and chin deviation, resulting in significant facial asymmetry and anterior crossbite. Clinical and radiographic examinations confirmed skeletal Class III malocclusion with mandibular laterognathia and hyperdivergence. A multidisciplinary team devised a comprehensive treatment plan involving orthodontics and orthognathic surgery. Treatment: Orthodontic preparation included standard Edgewise appliances and sequential archwires for leveling and alignment. The patient underwent maxillary advancement, asymmetric mandibular setback (5 mm left, 3 mm right), and genioplasty. Postsurgical care included intermaxillary elastics and continued orthodontic refinement. Results: Post-treatment assessments showed correction of facial asymmetry, improved dental occlusion, and harmonious facial balance. Cephalometric analysis confirmed skeletal improvement, and the patient reported enhanced aesthetic and psychosocial satisfaction. Conclusion: A multidisciplinary, patient-centered approach combining orthodontics and surgery is essential in treating skeletal Class III malocclusions with asymmetry. This strategy yields functional, aesthetic, and psychological benefits, emphasizing the importance of individualized planning and precise execution.
