In Reply.—Drs Erenberg and Nowak's work with palatal grooves in neonates has been extensive. The use of a dental cast to define such grooves is certainly more exact than the measurement of groove depth in our study. Our lower incidence of significant (>0.5-cm depth in our study) palatal grooves is most likely tied to the older mean gestational age of the group ventilated for less than seven days. We assume that unusual pressure from the tube and palatal growth together contribute to the formation and severity of the groove. Our total number of infants who weighed less than 1000 g and who were ventilated for less than seven days was too small to draw definitive conclusions.
