Cervical vertebral maturation of female children with orofacial clefts.

Objective

To evaluate the skeletal maturation of girls with orofacial clefts using the cervical vertebral maturation method.

Design

Case-control study.

Setting

The School of Stomatology, Peking University. Patients : A total of 173 girls with cleft lip and/or palate from 8 to 16 years old were compared with 1038 age-matched girls without clefts.

Results

In the 8- to 9-year-olds, most of the girls from both groups were in cervical stage 1. In the 14- to 15-year-olds and 15- to 16-year-olds, almost all the girls from both groups were in cervical stages 5 and 6, and most of the 15- to 16-year-old girls were in cervical stage 6. Differences existed in each year for 9- to 14-year-olds, which was confirmed by statistical analysis. After ordinal logistical regression of data from girls 9 to 14 years of age, girls of the same age in the non-cleft lip and/or palate group were associated with 1.559 times the odds of having achieved higher cervical stages than those in the cleft lip and/or palate group. Most girls without cleft lip and/or palate were in cervical stages 3 and 4 in the 11- to 12-year-olds; whereas, it was not so obvious in the girls with cleft lip and/or palate. By the age of 12, girls with cleft lip and/or palate had 2.667 times the risk of delayed cervical stage 3, and the 95% confidence interval for the odds ratio was 1.013 to 7.019.

Conclusions

Girls with cleft lip and/or palate are at a higher risk of delayed pubertal growth.
