Prevalence of cleft uvula among school children in kindergarten through grade five.

The purpose of this study was to determine the prevalence of bifid uvula among elementary school children in grades K through 5. Three examiners performed independent intraoral examinations of 709 children enrolled in a Jacksonville, Florida metropolitan public school. The structure of the uvula was evaluated as normal or bifid. If bifid, the cleft was classified as: (a) notched, (b) extending up to 1/4 the length of the uvula, (c) extending from 1/4 to 3/4 of the length of the uvula, or (d) extending the full length of the uvula. Prevalence of some form of uvular cleft was observed among 16 (2.26%) of the children while full length uvular cleft was found in only two (0.3%) of the children. These findings are congruent with percentages reported in other studies. It is recommended that speech-language pathologists identify children with bifid uvulas and provide appropriate counseling and follow-up study.
