Objective: Skeletal Class III malocclusions are dentofacial anomalies characterized by maxillary
hypoplasia, mandibular hyperplasia, or a combination of both, causing severe aesthetic and
functional problems. Since orthodontics alone remains insufficient for severe skeletal abnormalities,
multidisciplinary orthodontic and surgical collaboration is essential. Bimaxillary orthognathic surgery
is the gold standard protocol to optimize the facial profile, protect the airway, and ensure stable
occlusion.
Case: An 18-year-old female patient presented to our clinic complaining of a protruded lower
jaw, biting difficulties, and aesthetic concerns. Following clinical and cephalometric evaluations,
she was diagnosed with skeletal Class III malocclusion. After completing preoperative orthodontic
decompensation, bimaxillary orthognathic surgery was planned under general anesthesia. During the
operation, a Le Fort I osteotomy was performed; the maxilla was advanced and impacted superiorly
to adjust the occlusal plane. Simultaneously, a Bilateral Sagittal Split Osteotomy (BSSO) was
performed for mandibular setback. Bone segments were stabilized via rigid internal fixation using
titanium mini-plates and screws. The surgery concluded smoothly, with no infection or neurosensory
complications observed postoperatively. The patient’s occlusion was successfully corrected to a Class
I relationship.
Conclusion: In severe Class III malocclusion cases, a double-jaw surgical approach involving maxillary
advancement/impaction and mandibular setback provides superior aesthetic harmony and functional
stability compared to single-jaw interventions. Accurate indications and precise 3D surgical planning
significantly improve the patient’s chewing functions, psychosocial status, and overall quality of life.
