Morphometric Evaluation and Clinical Significance of Prominent Superficial Landmarks of the Cranium
Öz
Abstract
Aim: The aim of this study is to evaluate the localization and morphometry of important points such as nasion, lambda, arcus superciliaris, sutura lambdoidea, and sutura occipitomastoidea using Bregma as the reference point among the prominent superficial landmarks of the neurocranium. We believe that distinguishing these external points in radiological imaging and guiding surgical interventions will be beneficial.
Materials and Methods: This study was conducted on dry skulls in the student laboratory of the Department of Anatomy, Selçuk University Faculty of Medicine. A total of 52 skulls of unknown age, gender, and population were examined. However, 21 damaged skulls were excluded due to lack of integrity, and a total of 31 skulls were evaluated. On these materials, points such as bregma, pterion, asterion, nasion, lambda, arcus superciliaris, sutura lambdoidea, and sutura occipitomastoidea were identified, measurements were made, and the presence of wormian bones was recorded.
Results: Among the evaluated 31 dry skulls, the Bregma-Nasion distance ranged from 92 to 120 mm (mean 108.3±7.3 mm), the Bregma-Lambda distance ranged from 92 to 127 mm (mean 107±7 mm), the Bregma-Pterion right distance ranged from 82 to 110 mm (mean 91±6 mm), the Bregma-Pterion left distance ranged from 81 to 105 mm (mean 91±5 mm), the Bregma-Arcus superciliaris right distance ranged from 82 to 110 mm (mean 98±7 mm), and the Bregma-Arcus superciliaris left distance ranged from 84 to 109 mm (mean 98±7 mm). The Nasion-Lambda distance ranged from 184 to 245 mm (mean 215.4±12.3 mm). Wormian bones were found in all the evaluated dry skulls. Among the regions examined, the most common area was the sutura lambdoidea, while the least observed area was bregma.
Conclusion: The measurements obtained from this study provide current data on the region’s anatomy and may guide the planning of surgical interventions.
