Expansion Orbitotomy: Another Approach to the Orbital Floor

Surgeons encounter obstacles on the orbital floor reconstruction because of its narrow operative field. In particular, such procedure tends to be more difficult when the orbital contents are stuck between bone defects and are not easily restored. Tugging the soft tissue using forceps or mosquitoes could injure the soft tissues. Tessier infraorbital marginotomy could be helpful to solve such problem. However, his method is too invasive and cannot be easily applied. In this study, we describe a modification of Tessier inferior orbitotomy. Our method is to expand the fractured hole through osteotomy of fractured margin. Advantages of this technique are simpler and less invasive when the orbital contents are stuck between bone fragments.
