Postoperative Outcomes in Condylar Hyperplasia: Proportional Condylectomy Versus Orthognathic Surgery

Area of Science:

• Oral and Maxillofacial Surgery
• Orthodontics
• Plastic Surgery

Background:

• Facial asymmetry due to condylar hyperplasia presents complex management challenges.
• Treatment strategies for unilateral condylar hyperplasia (UCH) are debated, particularly regarding surgical interventions.
• Assessing outcomes of different surgical approaches is crucial for patient care.

Purpose of the Study:

• To compare the efficacy of proportional condylectomy versus orthognathic surgery in treating unilateral condylar hyperplasia (UCH).
• To evaluate esthetic, functional, and patient satisfaction outcomes between the two surgical groups.
• To provide evidence-based insights into the management of facial asymmetry caused by UCH.

Main Methods:

• Retrospective study comparing two groups of UCH patients: proportional condylectomy (n=15) and orthognathic surgery (n=22).
• Analysis of facial, occlusal, and skeletal changes using photographic and radiologic records.
• Assessment of patient satisfaction through a standardized questionnaire.

Main Results:

• Both proportional condylectomy and orthognathic surgery demonstrated significant improvements in facial asymmetry, dental midline, and occlusal plane canting.
• Group A (proportional condylectomy) showed improvements of 58.5% in chin deviation, 56.5% in dental midline, and 70.0% in occlusal plane canting.
• Group B (orthognathic surgery) showed improvements of 60.1% in chin deviation, 79.4% in dental midline, and 64.9% in occlusal plane canting.
• High patient satisfaction was reported in both groups, with no significant differences in postoperative results, esthetics, or functional satisfaction.

Conclusions:

• Proportional condylectomy is an effective treatment for unilateral condylar hyperplasia (UCH), yielding outcomes comparable to orthognathic surgery.
• Both surgical techniques achieve significant improvements in facial esthetics, occlusion, and skeletal alignment.
• Patient satisfaction levels are high and similar between the two treatment groups, supporting proportional condylectomy as a viable option for UCH management.
