A Prospective Study of Mental Nerve Involvement in Anterior Mandibular Fractures
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.
