Abstract
We report a case of a 67-year-old man who underwent reconstruction surgery several times to place a metal plate on both sides of the DP flap after mandible and gingiva tumor excision by an oral surgeon in another hospital; however, it became infected and necrosis, and the mandible was lost. As a result, a huge tubed flap was made in the left thorax and the abdominal part; however, the patient opted for another treatment opinion and came to our hospital. The patient suffered a loss and was not able to close his mouth at all. We combined a free rectus abdominis muscle flap and ported tubed flap in the mandible and oral floor part and used them for efficient reconstruction of the mandible. After the surgery, the combined flap was completely engrafted and satisfactory results were obtained in terms of function and esthetic reconstruction.
