C-shape extended transconjunctival approach for the exposure and osteotomyof traumatic orbitozygomaticomaxillary deformities

In the treatment of post-traumatic deformities of the orbitozygomaticomaxil lary complex resulting from trauma, the most appropriate exposure must be u sed. The choice of exposures includes the bicoronal approach and the perior bital incisions. When the whole orbitozygomatic complex is malpositioned, t he bicoronal approach is desirable; this can be combined with buccal and ey elid incisions. However, the bicoronal approach is complicated by a longer duration of oper ation time, postsurgical scars that tend to show, and potential damage to t he temporal branch of the facial nerve. A new approach using a C-shape extended transconjunctival approach is possi ble to have one field of vision to osteotomize the frontozygomatic suture, the lateral orbital wall, inferior orbital rim, lateral maxillary buttress, and zygomatic arch. It fakes less operating time and the post-surgical sca rs are shorter than the bicoronal approach.
