Use of vascularized iliac crest with internal oblique muscle flap for mandible reconstruction

Abstract

In the last decade, immediate reconstruction of maxillary bones following extensive trauma, large oncological defects, or late effects of radiation therapy has proved to be a reliable morpho-functional reconstruction technique. Use of the vascularized iliac crest with an internal oblique flap has become our flap of choice for mandible reconstruction when there is no need for overlying facial skin or oral sphincter reconstruction, and for bone segments within 6-15 cm of length. The advantages of this composite bone flap are the large and resizable bone stock available, the quality of bone transferred with an optimal height, depth, and contour of bone to maintain a good facial profile, and the possibility to reconstruct properly the oral lining, with a portion of the internal oblique muscle flap raised with the same pedicle that epithelializes during the healing stages. We present the experience of the Department of Maxillofacial Surgery of "S. Maria della Misericordia" Regional Hospital in Udine, Italy.
