The factors which affect mid-facial growth in unilateral and bilateral cleft lip and palate

[摘要] Aims To ascertain which factors influence mid-facial growth, when evaluated with the 5-year index. Method This was a retrospective cohort longitudinal study. One hundred and eighty-seven unilateral and bilateral cleft lip and palate patients that had undergone cleft lip and palate surgery, from 2000 to 2009, were included. There were two different but consistent techniques being used for the last 13 years. Factors investigated were surgical technique, severity of the cleft, anomalies of deciduous lateral incisors, and presence of bone in the cleft. Clinical notes, the cleft database, radiographs and dental study models were used. Comparisons were made using chi-squared tests at p<0.05. Results Technique B had significantly worse mid-facial growth for unilateral and bilateral cleft lip and palate patients (p<0.001; p=0.045) and a significantly higher number of cases with bone forming in the cleft (p=0.014; p=0.005). The severity of the cleft had a significant effect on the mid-facial growth (p=0.018; p=0.031). Anomalies of deciduous lateral incisors did not have a significant affect. A trend was present between the presence of bone and worse mid-facial growth. Conclusions Surgical technique, the severity of the cleft and the presence of bone have a significant effect on mid-facial growth.
