A Prospective Study of Mental Nerve Involvement in Anterior Mandibular Fractures

Govindharaj V and Boopathi K .

Abstract


Aims and Objectives: To study the aetiology and

anatomic distribution of anterior mandibular fractures. To

evaluate the involvement of mental nerve in anterior

mandibular fractures. To assess the relation between rigid

fixation and mental nerve injury. Materials and Methods:

A prospective was designed with an intention to analyse

patients fulfilling the inclusion criteria. The data was

collected and preserved in a specifically designed protocol.

Etiology, fracture characteristics, treatment, sensory

disturbances (if any) were recorded. Patients were

followed up for a minimum of 6 months. Results: A total of

46 patients presenting with 59 fractures were studied. The

study group consisted of thirty-seven males (78.7%)

and nine females (19.2%) with a gender ratio of

4:1. Commonest location of fracture was symphysis (47%).

Preoperative mental nerve disturbance was noticed in

8 patients(20%), which increased to 37% in the immediate

postoperative period. Conclusion: Road Traffic Accidents

is the commonest cause of mandible fractures, and there

is significant association with alcohol intoxication.

Immediate postoperative incidence of sensory disturbance

is high and these patients show spontaneous recovery in

the follow up period.
