Crescimento quantitativo da laringe fetal humana: estudo alométrico entre a 9ª e a 38ª semanas pós-concepção

Abstract

 

The ponderal growth of the larynx was studied in human fetal period between the 9th and 38th weeks post-conception (w.p.c.). The larynx weight (in grams - g) was related with body weight (in grams -g) using the allometric equation Ÿ= axb. Our results indicated that ralative growth of the larynx is allometric negative (b= 0,55, p < 0,001). These data are important in estimating the fetal gestational age after non-invasive investigation (MR, CT and ultrasound).
