We propose a new classification of subcondylar fractures of the mandible based on ramal height shortening and degree of fracture angulation and present our treatment experience using this classification system.

Eighty patients with subcondylar fractures of the mandible were evaluated. We categorized the fractures into 3 classes: Class 1 (minimally displaced), fracture with ramal height shortening: <2 mm and/or degree of fracture displacement: <10°; Class 2 (moderately displaced), fracture with ramal height shortening: 2 to 15 mm and/or degree of fracture displacement: 10 to 35°; Class 3 (severely displaced), fracture with ramal height shortening: >15 mm and/or degree of fracture displacement: >35°. Our treatment protocol is closed treatment for Class 1 fractures; either closed or open treatment for Class 2 fractures; and open treatment for Class 3 fractures.
