Orbitozygomatic approach by transposition of temporalis muscle and one-piece osteotomy

BACKGROUND A more simplified and easier technique for the orbitozygomatic approach is sought. We have developed a new modification to fully expose the temporal base before using one-piece craniotomy. METHODS By transposing the temporalis muscle underneath the zygomatic arch before osteotomy, the temporal base and the inferior orbital fissure can be fully exposed. Craniotomy is made in one piece with the frontotemporal and orbitozygomatic bone together by using a high-speed drill. RESULTS AND CONCLUSIONS Osteotomy was easy and the cosmetic result was satisfactory. This technique also allows better access to the subtemporal region without removing the zygomatic arch, (C) 1999 by Elsevier Science Inc.
