A Cross Sectional Discriptive Study of Analysis of Lambdoid And Squamous Sutures Closure by Ct Scan for Age Estimation
Keywords:Age determination, Lambdoid suture, Squamous suture, CT scan, Identification.
Background– Identification is fixation of an individuality by various physical and biological parameters.
An individual’s age determination is very important in various civil and criminal medicolegal cases. Age
estimation by cranial sutures closure is an old method. This study was conducted to analyze closure of
lambdoid and squamous sutures for age estimation in living individuals by CT scan.
Objectives– To study the pattern of closure of lambdoid and squamous sutures with relation to age of
person. To detect bilateral and bisexual variations in same.
Materials & Methods–We had done a descriptive cross-sectional study by CT scan head of 130 living adult
persons and analyzed them for closure status of lambdoid and squamous sutures in co-relation to age.
Results– In Lambdoid suture complete closure observed 5yrs earlier in upper 2/3rd(L1&L2) parts of right
side than left side in both sex while while complete closure observed very late ages(>75yrs) or not at
all(lapsed union) in lower 1/3rd(L3) part. Both sides of Squamous sutures follow more or less same pattern
for closure in relation to age and sex while complete closure observed at very late ages(>75yrs) or not at
Conclusion– Closure of Lambdoid and Squamous sutures should be used only as corroborative to other
criteria and evidences for age estimation as they might be unreliable as standalone until proven otherwise.
