Observation of\n DDSP<\/jats:styled-content>\n is straightforward in that it is an all or nothing event, whereas observation of\n PI<\/jats:styled-content>\n is subjective and interpretation may vary between clinicians.\n <\/jats:p>\n <\/jats:sec>\n \n Objectives<\/jats:title>\n \n The aim of this study was to attempt to characterise\n PI<\/jats:styled-content>\n and to investigate endoscopic features that precede\n DDSP<\/jats:styled-content>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n A retrospective study on the endoscopic observations of\n T<\/jats:styled-content>\n horoughbred racehorses referred for high\u2010speed treadmill endoscopy was performed. Endoscopic observations were reviewed during the last 10\u2009s of the exercise test or the last 10\u2009s prior to\n DDSP<\/jats:styled-content>\n . The degree of axial deviation of the aryepiglottic folds (\n ADAF<\/jats:styled-content>\n ), the conformation of the epiglottis, the conformation of the soft palate and the amount of obstruction of the\n rima glottidis<\/jats:italic>\n by the soft palate (i.e. soft palate stability) were assessed.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 72 horses were included in this study, of which 7 showed no evidence of\n PI<\/jats:styled-content>\n . Of the 65 horses with\n PI<\/jats:styled-content>\n , 30 (46%) developed\n DDSP<\/jats:styled-content>\n . There were significant associations between the stability of the soft palate, epiglottic conformation and\n ADAF<\/jats:styled-content>\n . Furthermore, development of\n DDSP<\/jats:styled-content>\n was associated with increased severity of\n PI<\/jats:styled-content>\n and\n ADAF<\/jats:styled-content>\n and with changes in epiglottic conformation.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n This study has characterised the endoscopic features associated with\n PI<\/jats:styled-content>\n and identified certain characteristics that precede\n DDSP<\/jats:styled-content>\n .\n <\/jats:p>\n <\/jats:sec>\n \n Potential relevance<\/jats:title>\n \n These observations may assist veterinary surgeons in recognising\n PI<\/jats:styled-content>\n and the prodromal signs of\n DDSP<\/jats:styled-content>\n .\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/evj.12004","type":"journal-article","created":{"date-parts":[[2012,10,12]],"date-time":"2012-10-12T07:27:01Z","timestamp":1350026821000},"page":"454-459","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Characteristics of palatal instability in\n T<\/scp>\n horoughbred racehorses and their association with the development of dorsal displacement of the soft palate"],"prefix":"10.1111","volume":"45","author":[{"given":"K.","family":"Allen","sequence":"first","affiliation":[{"name":"Langford House Equine Hospital University of Bristol UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Franklin","sequence":"additional","affiliation":[{"name":"Langford House Equine Hospital University of Bristol UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,1,7]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.2746\/042516406778400583"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1053\/jvet.2002.36009"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.2746\/0425164044864453"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0737-0806(99)80309-8"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3292.2010.00060.x"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3306.2011.00516.x"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1751-0813.1995.tb15020.x"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.2746\/042516408X313616"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3306.2010.00033.x"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3306.2010.00281.x"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3306.2002.tb05452.x"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1053\/jvet.2001.21389"},{"key":"e_1_2_8_14_1","unstructured":"Tsukroff E.
