Abstract :

Among foetuses of different population, mesocephalic, achycephalic and hyperachycephalic heads have been frequent. The present research was conducted to study various head types and its distribution among foetuses after first trimester up to full term of pregnancy by ultrasonography at RIMS,RAIPUR. Brachycephalic (5.2%) head was more frequent than hyperachycephalic (3.2%) during first four weeks of second trimester. During 16.1–20 weeks of gestational age, achycephalic head type (6.4%) predominated over mesocephalic and hyperachycephalic. Mesocephalic head (4%) ranked next to achycephalic (5.2%) during 20.1–24 weeks. But during 24.1–32 weeks, mesocephalic head predominated over achycephalic head. During subsequent age interval, achycephalic type (17.2%) outnumbered mesocephalic type (10.4%) and continued to dominate (11.2%) over mesocephalic head (2.8%) up to full term. Overall, achycephalic foetal head type constituted the major chunk (54%; CI 82.11 ± 1.39) followed by mesocephalic (33.6%; CI 77.88 ± 1.36) and hyperachycehalic head (8.4%; CI 86.67 ± 1.16). Dolichocephalic head was noted to be the least (4%; CI 73.2 ± 3.16) among the foetuses during 12.1 – 40 weeks of gestation. The present study concluded that the commonest type foetal skull was achycephalic followed by mesocephalic whereas dolichocephalic was the least common type in RAIPUR,CHHATTISGARH.
