Long-term stability and condylar status evaluation following distraction osteogenesis for severe mandibular retrognathia with mild obstructive sleep apnoea: a 10-year experience

This case report highlights role of distraction osteogenesis (DO) in the treatment of severe mandibular retrognathia with mild obstructive sleep apnoea (OSA), highlighting its ability to address complex maxillofacial deformities while ensuring long-term stability and temporomandibular joint (TMJ) health. Severe mandibular retrognathia with mild OSA, causes functional and aesthetic concerns. DO chosen over conventional orthognathic surgery due to its ability to gradually lengthen the mandible and create new bone formation, thereby correcting mandibular size and improving function and aesthetics. Significant improvement in facial aesthetics, correction of skeletal base relations, optimization of dental occlusion, and reduction in OSA symptoms confirmed through post-treatment assessments including cephalometric analysis and polysomnography (PSG). Ten-year follow-up demonstrated excellent stability of treatment outcomes with sustained improvement in facial aesthetics and absence of OSA symptoms. Cone beam computed tomography (CBCT) imaging confirmed the long-term health and functionality of the TMJ complex.
