Background:
Few published large series have described a surgical approach to maxillary skeletal reconstruction on the basis of the extent of maxillectomy.
Methods:
We have reviewed a 10-year experience with 38 consecutive maxillary reconstructions with respect to maxillectomy defects, reconstructive procedures, reconstructed buttresses, and functional and aesthetic outcomes.
Results:
Maxillectomy defects were classified into three categories on the basis of the buttress concept. Buttress reconstruction was most frequently performed in category III maxillary defects (56%), followed by category I (50%) and category II (20%). The vascularized composite autograft included the rectus abdominis myocutaneous free flap combined with costal cartilage, and the latissimus dorsi myocutaneous free flap combined with the V-shaped scapula is an effective method for reliable reconstruction of both skeletal and soft tissues.
Conclusions:
A critical assessment for skeletal defects and associated soft tissue defects is essential for an adequate approach to solve complex problems in maxillary reconstruction. On the basis of retrospective analysis of this series, a reconstructive algorithm for surgical management of maxillectomy defects is proposed.
