Morphometric Evaluation, Locational Relationship, and Surgical Significance of the Maxillofacial Region Landmarks

SUMMARY: The aim of this study was to examine the localization of the landmarks in the maxillofacial region and their relations with each other and to evaluate them morphologically and clinically. Our study included 41 dry adult human skulls of unknown age and sex of Anatolian population. Statistical analysis of the data obtained in our study was performed with SPSS v.20.0 software (IBM Corp., Armonk, NY, USA). Statistical significance was accepted as P ? 0.05. Whereas the mean right supraorbital depth (SOD) value was significantly greater than the mean left SOD value (p < 0.05), no significant difference was found between the right and left sides in all other measurements (p > 0.05). Correlation values in our study varied between -0.156 and 0.612. The highest correlation value was obtained in the positive direction between the orbital height (OH) and supraorbital foramen-infraorbital foramen (SOF-IOF) measurements (r = 0.612, p < 0.001). We believe that measurements of the orbit, SOF, and IOF and our data on their localizations, along with the relationships that we observed in our study will allow surgeons to avoid damaging the neurovascular bundles during surgical interventions and local anesthesia procedures in the frontal, periorbital, and maxillofacial regions.
