Experience with 24 Cases of Reconstructive Anterior Skull Base Surgery

Classification and Evaluation of Postoperative Facial Appearance

Abstract

This article details our experience with 24 cases of anterior skull base reconstruction after tumor resection. They were classified into four types according to the resected region. In 11 cases of type I resection, the orbital part of frontal bone and/or cribriform plate of ethmoid bone were resected. In two cases of type II resection, the orbital contents and partial orbital bone were resected with the addition of type I. In five cases of type III resection, the maxillary bone was resected with the addition of type II. In six cases of type IV resection, the zygomatic bone and/or facial skin were resected with the addition of type III. The tumor originating from intracranial region was 25% of this series and all of them belonged to type I. The tumor originating from extracranial region tumor was 75% and its resected region was more extensive. In type I and II resections, the cranial flap, radial forearm free flap, or a combination of the two was used for reconstruction. The rectus abdominis myocutaneous/muscle free flap was used for reconstruction of massive defects in type III and IV defects. Total incidence of postoperative complications was 16.7%. Donor site deformity of the cranial flap at the frontal and temporal region in types I and II resections and facial contour deformity in zygomatic region and defect of upper and/or lower palpebra in type IV resection were major problems with postoperative facial appearance. Although use of the rectus abdominis myocutaneous free flap combined with costal cartilages improved the midfacial contour, palpebral reconstruction remained an unsolved problem in reconstructive skull base surgery. The reconstructive goals in skull base surgery are not only to obtain safe and reliable skull base reconstruction but also to restore the facial appearance postoperatively.
