Objective: To discuss the application and therapeutic effect of tunable guide device in correction of prominent mandibular angle.
Methods: Since 2007, 50 cases with prominent mandible angle underwent mandible angle osteotomy with the tunable guide device. The patients were followed up for 3-6 months.
Results: No severe complication happened. Local seroma occurred in one case. Improved esthetic results were achieved at both frontal and oblique view.
Conclusions: The mandibular angle osteotomy with the tunable guide device makes the procedure safe and easily performed.
