[Transmasseter approach to mid-and-low condylar fractures by mini-retromandibular access].

OBJECTIVE

To explore a new access for internal rigid fixation of mandibular mid-and-low condylar fracture.

METHODS

16 patients of unilateral mid-and-low condylar fractures were treated with a 2cm mini-retromandibular approach. The subcutaneous tissues superficial to the superficial muscular aponeurotic system (SMAS) were dissected forward that parallel to the masseter muscle fiber bundles, aiming to the fracture. After exposing the fracture, the fracture segments were reduced and fixed under sufficient exposure.

RESULTS

Correct anatomic reduction and occlusion were achieved in all cases. Additionally, all patients showed normal articular function and the surgical scars were barely visible.

CONCLUSION

The transmasseter approach by retromandibular access is one of the feasible methods for curing mid-and-low condylar fracture, which minimizeing the risk of facial nerve injury and reducing the visible scars.
