Comprehensive Strategies of Flap Design for Repairing Cranium Exposure or Defects After Malignant Tumor Resection

Abstract

Free tissue transfer is a great method for the reconstruction of craniofacial defects, especially in complicated situations such as calvarial defects and dura exposure. Latissimus dorsi muscle flap, anterolateral thigh flap, and radial forearm flap are 3 commonly used flaps that have distinct characteristics. The objective of the present study is to share our experiences with microvascular free flap reconstruction of cranium exposure or defects and to compare distinct microvascular free flap options. The authors reviewed 8 cases that received resection and reconstruction of craniofacial tumors. Perioperative and reconstructive techniques employed to improve flap survival, esthetic outcome, and prevent complications in these patients were retrospectively detailed. In addition, the advantages and disadvantages of latissimus dorsi muscle flap, anterolateral thigh flap, and radial forearm flap were illustrated in this study. The authors believe that taking advantage of these flaps according to the characteristics of defects and flaps will contribute to a good functional and esthetic outcome.
