The effect of dynaCleft® on presurgical orthopedics in bilateral cleft lip and palate patients

Abstract

Aims: The aim of this study was to determine the effects DynaCleft® has on patients with bilateral cleft lip and palate. Subjects and Methods: Comparative data were collected from a total of 46 infants diagnosed with bilateral cleft lip and palate between 1981 and 2017. Twenty-three infants were treated with DynaCleft® and an obturator and 23 infants received an obturator only. Maxillary impressions were taken at each infant's initial clinic visit and again on the day of his/her surgical cleft lip repair. Differences in maxillary retraction, sagittal repositioning, and cleft widths were compared between the two groups. Statistical Analysis Used: Paired t-tests were used to determine if there was significant change before and after DynaCleft® therapy, and two-sample t-tests were used to compare the data between the two study groups. Results: Clinically, DynaCleft® averaged more maxillary retraction and cleft size reduction on both the right and left sides compared to the control group. Within the DynaCleft® group, a statistically significant difference was found for premaxillary retraction on both the right and left sides. However, all the other comparisons between the two groups were not found to be statistically significant. Conclusions: DynaCleft® as a presurgical orthopedic therapy may help to limit uncontrolled physiological changes and reposition the premaxillary segment, while reducing cleft widths prior to definitive lip surgery.
