RT Journal Article SR Electronic T1 Anterior fontanelle size in the neonate. JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 81 OP 83 DO 10.1136/adc.50.1.81 VO 50 IS 1 A1 Davies, D P A1 Ansari, B M A1 Cooke, T J YR 1975 UL http://adc.bmj.com/content/50/1/81.abstract AB A simple method is described for measuring the area of the anterior fontanelle at birth. Normal values in preterm and term infants suggest enlargement of the fontanelle with gestational age. Small-for-dates infants have significantly larger anterior fontanelles than either preterm or term infants. Knowledge of the normal variation in anterior fontanelle size may be of help in the early diagnosis of congenital hypothyroidism or provide a clue to other disorders of skeletal development.
