Long-term use of orotracheal tubes has been associated with palatal groove formation, acquired cleft palate, and defective primary dentition. To determine the incidence of palatal groove formation, maxillary impressions were made of 63 neonates and infants who required orotracheal intubation for one to 62 days. A palatal groove was present in 47.6% of these neonates and infants. The incidence of palatal groove formation increased with a longer use of tubes, being 87.5% in those neonates and infants requiring tubes for more than two weeks.
长期使用口气管导管与腭沟形成、后天性腭裂和乳牙列缺陷有关。为了确定腭沟形成的发生率，对63例需要口气管插管1至62天的新生儿和婴儿进行了上颌印模。这些新生儿和婴儿中有47.6%存在腭沟。腭沟形成的发生率随着导管使用时间的延长而增加，在那些需要使用导管超过两周的新生儿和婴儿中，发生率为87.5%。
