We can see the mental foramen along the superior border of the mandible. The dental rehabilitation of the patient was planned using implants for which adequate alveolar height is required. Hence alveolar distraction of the symphyseal region was planned. Under nasoendotracheal intubation, crestal incision was placed from 36 to 46 region and full thickness flap reflected. The mental nerve was identified and carefully protected. Horizontal osteotomy cut was marked along the buccal cortex and the vertical osteotomy cut is marked above the mental nerve. Distractor device positioned and fixed. Osteotomy is then completed along the lingual cortex. The device is checked by distracting the segments. Wound closure done. Patient extubated, recovery spontaneous and uneventful.
