ABSTRACT
In the present study, herewith comparison is done for closure of squamous suture of skull of living individuals from Punjab and Rajasthan. The cases studied in Punjab are 100 individuals between the age group of 45 years to 70 years with age interval of five years and twenty cases from each age group were studied who were CT scanned for closure of squamous suture at Rajindra Hospital Patiala (Punjab). In Rajasthan (SMS Hospital Jaipur), X-ray examination of 100 individuals was done having age group 40 years to 70 years with age interval of ten years in male and female separately for squamous suture closure and accordingly the squamous suture is divided into 2 parts-(1) Upper half(½), (2)Lower half (½). In both studies, squamous suture is studied ectocranially. It is seen that endocranially suture closure will not give reliable results and sometimes endocranially sutures remain unfused for whole life. No differences in right or left side of squamous suture have been reported by Todd and Lyon. Occasionally there is considerable sclerosis and condensation along the various sutures, particularly sagittal, squamous and coronal suture.
