DETERMINATION OF AGE BY STUDY OF CLOSURE OF ENDOCRANIAL SUTURES
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2016, Vol 5, Issue 46
Abstract
BACKGROUND Skull is the best preserved remains of the recovered skeleton that resists putrefaction and not easily destroyed. If determination of age by means of study of endocranial closure of suture can give a precise result, it could be a reliable method in criminal cases such as rape, murder and criminal responsibility. Other methods available to determine the age of the individual can only be determined by the age in decades. OBJECTIVES The objectives of the present study were to observe the chronology and pattern of endocranial suture closures – sagittal, coronal and lambdoid suture; to determine the correlation between closure of endocranial suture and age. Further, we would like to find the bilateral and bisexual variation in closure of endocranial sutures. MATERIALS AND METHODS Our study was conducted in 100 cases of age above 20 years. Acsadi-Nemeskeri scale of suture closure was used to assess the age after removing the calvaria by craniotome. Scale of endocranial suture closure from 0–4 was observed in 16 parts as done by Acsadi-Nemeskeri. The observations were analysed using SPSS 11.5 statistical software. RESULTS Endocranial fusion of sagittal, coronal and lambdoid suture, starts eventually between 20 and 29 years of age. Completion of suture closure occurs between 60 and 69 years in case of sagittal suture and between 50 and 59 years in case of coronal and lambdoid suture. There is no significant sexual variation and bilateral variation in endocranial suture closure. CONCLUSIONS Correlation between endocranial closure of suture and age is observed up to 50 years of age, but after 50 years there is no significant correlation. There is no bilateral variation in suture closure of lambdoid suture. Coronal suture closes earlier to sagittal and lambdoid suture endocranially. The endocranial closure of suture with respect to age is erratic and not suitable for precise estimation of age.
