a Preoperative frontal and side views of the patient in case 1 (patient 1, Table 1) who presented with severe scar contractures and adhesions from the mandible to the neck due to insufficient tissue. b Free osteo-cutaneous fibula flap harvested from the left lower limb. The flap was removed after osteotomy and fixed with miniplates (top).

Additional scar revision with skin grafting was performed on the neck after contracture-release. The patient experienced a satisfactory outcome with implant installation which was successfully achieved
