Magnitude of Myocutaneous Flaps and Factors Associated With Loss of Volume in Oral Cancer Reconstructive Surgery

Purpose: Myocutaneous flaps are often used to repair oral and maxillofacial defects after surgery for oral cancer; however, their volume decreases during the postoperative period. To facilitate treatment planning, the authors measured the extent of such postoperative flap volume loss and identified associated factors inpatients who underwent oral reconstruction with myocutaneous flaps. Materials and Methods: The authors designed and performed a retrospective observational study ofpatients who underwent reconstructive procedures involving rectus abdominal myocutaneous (RAM) or pectoralis major myocutaneous (PMMC) flaps at Tokai University Hospital, Kobe University Hospital, or Nagasaki University Hospital from April 2009 through March 2013. Flap type and other clinical variables were examined as potential predictors of flap loss. The primary outcome was flap loss at 6 months postoperatively. Correlations between each potential predictor and the primary outcome were examined using multiple regression analysis. Results: The subjects were 75 patients whose oral defects were reconstructed with RAM flaps (n = 57)or PMMC flaps (n = 18). RAM flaps exhibited a mean volume shrinkage of 22% at 6months postoperatively, which was less than the 27.5% displayed by the PMMC flaps, but the difference was not important. Renal failure, previous surgery of the oral region, postoperative radiotherapy, and postoperative serum albumin level were found to be meaningful risk factors for postoperative flap volume loss. Conclusion: The results of this study suggest that larger flaps should be used in patients who possess these risk factors or are scheduled to undergo postoperative radiotherapy. Future studies should examine the utility of postoperative nutritional management for preventing flap volume loss.;開始ページ : 644;終了ページ : 649;元資料の権利情報 : (C) 2016 American Association of Oral and Maxillofacial Surgeons
