Methods The centraivermian area (CVA) of the cerebellum was measured by head ultrasonography in 90 newborns including 65full - terms, 14 preterms and 11 small for gestational age infants (SGA). Results The average age of the newborninfants were 4.7d (3~7d). The mean CVA in full-terms was 5.81±0.8cm2, which was significantly greater thanthat in preterms (3.7±1.0cm2), and SGA (5.1±0.8cm2), respectively. However, when corrected for birth weight(BW), the ratio of CVA/BW in term SGA was 2.07, being signoficantly higher than the ratio of 1.72 in normalfull- term newborns. There was no dillerence between male and female infants. Statistically significantrelationships were lound between CVA and BW (r=0.8129, P<0.01) and between CVA and gestational age(r=0.7450, P<0.01). Conclusion The study provide some understanding on the grouth of the cerebellum, and thecerebellar measurement by cranial ultrasound is helpful for the assessment of neurological maturation in newborninfants.展开更多
