Left or right hand dominance in children with cleft lip and palate

The relationship between unilateral cleft lip, bilateral cleft lip, palatal clefting and left-right hand dominance was studied in 337 patients with cleft lip and/or palate aged between 3 and 14 years. There was no statistically significant difference in the laterality of handedness between different types of cleft nor between unilateral left and right sided cleft lip with or without cleft palate.
