In particular, among the 29 infants with birthweight &lt;1000 g, palatal groove was observed in 48% of these patients, and only 10% were normal. Infants with palatal groove were ventilated for considerably more days with oral endotracheal tube than those without palate groove, even after adjustment for gestational age, birthweight, and duration of oral duodenal tube placement (<jats:styled-content style=\"fixed-case\">OR<\/jats:styled-content>, 1.11). Establishment of oral feeding and disappearance of choking on milk were considerably delayed in infants with palatal groove. Transient oral feeding difficulty requiring thickened\u2010feed intervention was observed only in infants with palatal groove; on multi\u2010regression analysis this difficulty seemed to be induced by the palatal groove.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Palatal groove formation induced by oral endotracheal intubation occurs with a high frequency in preterm infants, and this is likely to affect oral feeding ability.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ped.13113","type":"journal-article","created":{"date-parts":[[2016,8,8]],"date-time":"2016-08-08T19:08:09Z","timestamp":1470683289000},"page":"171-175","source":"Crossref","is-referenced-by-count":10,"title":["Acquired palatal groove and delayed oral feeding in preterm infants"],"prefix":"10.1111","volume":"59","author":[{"given":"Masahiro","family":"Enomoto","sequence":"first","affiliation":[{"name":"Department of Pediatrics and Neonatology Takatsuki General Hospital Takatsuki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiromi","family":"Sezaki","sequence":"additional","affiliation":[{"name":"Neonatal Intensive Care Unit Takatsuki General Hospital Takatsuki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rie","family":"Muranishi","sequence":"additional","affiliation":[{"name":"Neonatal Intensive Care Unit Takatsuki General Hospital Takatsuki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yumi","family":"Sato","sequence":"additional","affiliation":[{"name":"Neonatal Intensive Care Unit Takatsuki General Hospital Takatsuki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shin","family":"Kikuchi","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Neonatology Takatsuki General Hospital Takatsuki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshinori","family":"Katayama","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Neonatology Takatsuki General Hospital Takatsuki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsuko","family":"Takei","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Neonatology Takatsuki General Hospital Takatsuki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hitoshi","family":"Ikegami","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Neonatology Takatsuki General Hospital Takatsuki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mio","family":"Sakuma","sequence":"additional","affiliation":[{"name":"Department of Clinical Epidemiology Hyogo College of Medicine Nishinomiya Hyogo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirotaka","family":"Minami","sequence":"additional","affiliation":[{"name":"Department of Pediatrics and Neonatology Takatsuki General Hospital Takatsuki Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,10,19]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(76)80617-8"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(76)80618-X"},{"key":"e_1_2_8_4_1","first-page":"974","article-title":"Palatal groove formation in neonates and infants with orotracheal tubes","volume":"138","author":"Erenberg A","year":"1984","journal-title":"Am.
