[Analysis of the complications following correction of mandibular angle prominence].

OBJECTIVE

To investigate the causes and the prophylactic measures for the complications following correction of mandibular angle prominence.

METHODS

From 1996 to 2001, a total of 203 patients with mandibular angle prominence underwent mandibular angle osteotomy.

RESULTS

Of them, 9 patients had postoperative complications, which included bleeding, hematoma, infection, mental nerve injury, labia scar, asymmetry, and steep mandibular angle.

CONCLUSION

The correction of mandibular angle prominence should be designed and performed precisely. Care must be taken to avoid severe complications like condyle fracture.
