Reconstruction of defects involving the mandible and floor of mouth by free osteo-cutaneous flaps derived from the foot.

Microsurgical transfer of a compound osteo-cutaneous free flap derived from the dorsal foot skin and second ray can provide a satisfactory reconstruction for defects of the mandible and floor of the mouth. The procedure is particularly recommended for anterior segment losses where a thin flap and a curved skeleton is required. The flap can be prepared at the time of tumour resection without inconvenience to either surgical team and the surgery does not significantly affect either the operative or post-operative condition of the patient. No external bony fixation is required and no case of non-union has been encountered.
