The aim of this study was to determine the location, variations, and connections of the zygomaticofacial foramina. A total of 171 zygomatic bones of unknown gender were examined. The number of zygomaticofacial foramina was found to be 299, with single, double, three, four, five, and six foramina being present in different proportions. Additionally, connections with the zygomatico-orbital and zygomaticotemporal foramina were observed. The distances between the zygomaticofacial foramen and various anatomical landmarks were also measured.
PurposeThe aim of this study is to reveal the location of the zygomaticofacial foramina, the variations of their numbers, and their connections between the zygomatico-orbital and zygomaticotemporal foramina.MethodsEthics committee approval of our study was received by the Istanbul Medical Faculty Clinical Research Ethics Committee (date:30.07.2021, number:358356). 171 zygomatic bones of unknown gender from the Department of Anatomy, Istanbul University, were included in this study. The number of zygomaticofacial foramina and their connections with the zygomatico-orbital foramen and the zygomaticotemporal foramina were examined. Also, the morphometric distances between the zygomaticofacial foramen were calculated. Evaluation of the data was done with SPPS v.21.ResultsThe number of zygomaticofacial foramina was found as 299. It was found single, double, three, four, five and six foramina, in 52 (30.4%), 52 (30.4%), 24 (14.03%), 10 (5.85%), 5 (2.93%), 1 (0.58%) zygomatic bone, respectively. Zygomaticofacial foramen was absent in 27 (15.8%) bones. Of these 299 foramina, 129 were found to be connected with zygomatico-orbital foramen and 23 with zygomaticotemporal foramen. It was noted that 147 zygomaticofacial foramina had no connection with any foramina. The distances between the zygomaticofacial foramen and the frontozygomatic suture, temporal process, maxillary process, the lowest point of the zygomatic bone, and orbital rim were found as 25.30 +/- 2.81mm, 18.74 +/- 3.56mm, 21.56 +/- 4.16mm, 18.72 +/- 2.57mm, 6.67 +/- 3.27mm, respectively.ConclusionConsequently, the location and variations of ZFF are of great importance for maxillofacial surgery and regional block anesthesia. Knowing its location and variations will help prevent complications during any surgical intervention in this region.
