Reconstruction of Acquired Segmental Mandibular Defects Using Pedicled Mandibular Muscle Flap and Evaluation of Speech Function and Aesthetic Outcomes

Abstract

Purpose: 

The purpose of this study was to investigate the clinical effect of pedicled mandibular osteomuscular flap in the reconstouring of repair of acquired segmental mandibular defects.

Patients and Methods: 

Thirteen patients with acquired segmental mandibular defects requiring secondary repair were included into the study. Pedicled mandibular osteomuscular flap was applied with strong internal fixation to repair the mandibular defects. The patients’ speech, swallowing function, and aesthetic changes were evaluated upon follow-up.

Results: 

The flaps were viable in all patients. Average speech function score was 7.6±0.6. All patients had a drinking test rating of grade I or II with good masticatory efficiency. The postoperative self-assessment Visual Analog Scale score of appearance was 7.8±0.8.

Conclusions: 

Pedicled mandibular osteomuscular flap is a viable choice in the secondary repair and reconstruction of mandibular acquired segmental defects. This flap could achieve better oral function with good aesthetic results.
