Technical Strategies

In the treatment of post-traumatic deformities of the orbitozygomaticomaxillary complex resulting from trauma, the most appropriate exposure must be used. The choice of exposures includes the bicoronal approach and the periorbital incisions. When the whole orbitozygomatic complex is malpositioned, the bicoronal approach is desirable; this can be combined with buccal and eyelid incisions.

However, the bicoronal approach is complicated by a longer duration of operation time, post-surgical scars that tend to show, and potential damage to the temporal branch of the facial nerve.

A new approach using a C-shape extended transconjunctival approach is possible 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 takes less operating time and the post-surgical scars are shorter than the bicoronal approach.
