A bifid or [[wikt:bifurcation|bifurcated]] uvula is a split or cleft uvula. Newborns with [[cleft lip and palate|cleft palate]] often also have a split uvula. The bifid uvula results from incomplete fusion of the palatine shelves but it is considered only a slight form of clefting. Bifid uvulas have less muscle in them than a normal uvula, which may cause recurring problems with middle ear infections. While swallowing, the soft palate is pushed backwards, preventing food and drink from entering the nasal cavity. If the soft palate cannot touch the back of the throat while swallowing, food and drink can enter the nasal cavity.<ref>{{cite web |url=http://health.ivillage.com/dental/0,,6hlv,00.html |title=Split Uvula: Is It a Problem? |access-date=23 September 2007 |archive-date=14 October 2007 |archive-url=https://web.archive.org/web/20071014220221/http://health.ivillage.com/dental/0,,6hlv,00.html |url-status=dead }}</ref> Splitting of the uvula occurs infrequently but is the most common form of mouth and nose area cleavage among newborns.
