Abstract

Abstract:

Condylar osteochondroma (OC) is a rare benign tumor of the mandibular condyle, often resulting in mandibular deviation or asymmetry. Traditionally, treatment involves a two-stage procedure—open tumor resection followed by orthognathic surgery to correct the associated dentofacial deformities. This approach carries a high risk of facial nerve injury and increased trauma due to multiple surgical interventions. At Shanghai Ninth People’s Hospital, digital technologies—including computer-assisted surgical design, endoscopy, navigation, personalized surgical guides, and customized implants—have been integrated to achieve precise control from preoperative planning to intraoral, minimally invasive tumor resection performed concurrently with orthognathic correction. This paradigm shift marks the transition of OC management from experience-based surgery to data-driven precision surgery.

Key words: condylar osteochondroma, digital surgery, minimally invasive surgery, precision surgery, personalized surgical design
