The fronto-orbito-zygomatic approach: surgical techniques and the bni experience


Journal Article

The various methods to perform the orbitozygomatic approach were examined in this study. OZ approaches were performed in 3 cadaveric specimens. Dissections were carried out in a stepwise fashion and recorded in stereo pictures. Three variations of the OZ approach were studied using one, two or three bone flaps. Attention was focused on the scalp incision, temporal muscle dissection, and the bone cuts. The medical records of 194 patients undergoing OZ approach between January 1992 and August 2000 were reviewed with attention to indications and complications of this approach. We found no difference in the exposure provided by the three variations of the OZ approach. However, the one-bone flap technique is more complex and time-consuming to perform. We conclude that the OZ approach performed with two bone flaps provides excellent exposure and is relatively simple and safe to perform. Trauma to the frontalis branch of the facial nerve with this approach can be avoided by using deep subfascial dissection of the temporalis fascia. Avoiding use of Bovie cautery for dissection minimizes atrophy of the temporalis muscle.
