Complexity of serrated sutures of a human skull

Abstract

Objective: to reveal the variability mechanism of complexity of serrated sutures of a human skull in the correlation with cranial form. Materials and methods. Researches of 253 arches of male and female skulls of patients at the age of 1 day-105 years without signs of cranial trauma or skeletal systemic diseases with absence of morphological signs of increase of intracranial pressure. Minimal (Min) and maximal (Max) values, average arithmetic (M), a mistake of average arithmetic (m) have been studied. For definition of reliability of average size difference parametrical and non-parametric statistical criteria were used: parametrical criterion (t-criterion of Student) applied for parameters submitting to the law of normal distribution (Lakin G. R, 1990). Distinctions of average arithmetic size were considered statistically authentic from 95% (p<0,05) a level of correct judgement (Plokhinskiy N.A., 1970). Results. On the surface of the arch lambdoid and coronal sutures in male skulls and lambdoid and sagittal sutures in female were found out to be of the greatest degree of complexity. Conclusion. The increase of complexity of sutures has been observed in children and adolescents; the directed asymmetry of sutures form is absent
