Analysis of condylar positioning in the temporomandibular joint following mandibular reconstruction: Introduction of a new classification system and assessment of influencing factors on displacement.

Objective: This study investigates the unsatisfactory outcomes observed in mandibular reconstruction procedures attributed to improper condylar positioning in the Temporomandibular Joint. It also proposes a systematic classification for post-reconstruction condylar positioning dissatisfaction.

Methods: A retrospective analysis was conducted on 337 patients who underwent tumor removal and mandibular reconstruction with vascularized osteocutaneous flaps.
