Clinical Criteria for Selective Exploration of Orbital Floor in Zygomaticomaxillary Complex Fractures.

Purpose: Exposing the orbital floor requires a surgical procedure that has its own challenges. Despite the meticulous clinical examination followed by sophisticated imaging modalities, orbital floor defects associated with zygomaticomaxillary complex (ZMC) fractures may evade diagnosis and appropriate management. If surgeons can decide about the need for orbital floor exploration in patients with ZMC fracture, the chance of a postoperative eyelid deformity can be prevented.

Modification of LeFort I osteotomy for severe maxillary vertical excess asymmetry.

A superfluous maxillary alveolus exacerbates excess of the vertical maxilla, and leads to a severe form of deformity. This poses a unique surgical challenge. In such conditions, the dimensions of the maxilla cephalad to the anterior nasal spine are normal, which limits superior repositioning of the maxilla when done in a conventional manner.
