Orbital Restoration Surgery in the Zygomaticotemporal and Zygomaticofacial Nerves and Important Anatomic Landmarks

WOS: 000264570300060PubMed ID: 19305251A variety of etiologies may result in functional and aesthetic deficiencies requiring orbital reconstruction. Fractures of the zygomaticomaxillary complex in the acute stage are frequently accompanied by sensory disturbances of the zygomatic nerve (ZN). The purpose of the current study was to describe the anatomic and topographic landmarks of the ZN in 18 adult human cadavers regarding the localization and dimensions in the orbit. The zygomaticotemporal (ZTN) and zygomticofacial nerves (ZFN) along the lateral wall of the orbit passed through the zygomaticotemporal and zygomaticofacial foramens, respectively. The angle between the ZTN and the ZFN within the orbit was approximately 42.21 degrees, The mean (SD) distance between the orbital opening of the ZTN and the meeting point of the ZTN was measured as 9.21 (5.18) mm. The mean (SD) distance between the orbital opening of the ZFN and the meeting point of the ZTN was calculated as 11.22 (4.25) mm. The mean (SD) distance between the orbital opening of the ZFN and the infraorbital margin of the orbit was 13.04. (3.21) mm. A detailed knowledge of the ZN's passage in the orbit is necessary for a Surgeon while performing maxillofacial Surgery. If these measurements are taken into account, there will be little surgical risk, and this will be helpful in identifying the extent of the operative field
