[The complications of nerve injury after the Le Fort I osteotomy].
OBJECTIVE
To investigate the incidence of the temporary and permanent sensory disturbance of the inferorbital nerve (ION) after Le Fort I osteotomy.


METHODS
Thirty patients with 60 inferorbital nerves were examined preoperatively, 1 week, 1 month, 3 months and 6-months after the operation of the Le Fort I osteotomy by using sharp-blunt testing, 2-point discrimination, electric pain response test (ZGK-1 electrometer).


RESULTS
The incidence of the temporary nerve impairment was 75% (45 of 60) and the obvious recovery was found after 1 to 3 months after the operation. No permanent sensory disturbance was found in the patients.


CONCLUSIONS
The inferorbital nerve injury after Le Fort I osteotomy is usually temporary and the sensory recovery was in 1 to 3 months after the operation.
