Objective: To compare the effects of presurgical infant orthopedics using 2 different methods, that is, the Dynacleft with Nasal elevator system versus the modified Grayson’s technique in patients with complete unilateral cleft lip and palate. Design: Prospective comparative cohort study. Materials and Methods: Twenty-eight patients were divided into 2 groups, that is, Group A consisting of 14 patients who underwent correction with DynaCleft with Nasal elevator system and Group B consisting of 14 patients undergoing correction using the modified Grayson technique. Maxillary cast measurements were taken at 2-time intervals (pre- and posttreatment) to assess various parameters using a laser scanning machine (C500 Solutionix) and 3D software (GOM Inspect). Similarly, standardized anterior–posterior and worm’s-eye view photographs using a custom box were taken and imported to Adobe Photoshop CS6 for measurements. Paired t test and independent t test were used to compare intra- and intergroup changes, respectively. Results: The analysis of cast (primary outcome) and photographic (secondary outcome) measurements showed improved nasal asymmetry and alveolar correction in both groups which showed no significant intergroup difference when assessed using the independent t test ( P > .05). Group A showed higher chances (42.8%) of causing a T-shaped defect (due to excessive mesial-inward rotation of the minor segment) when compared to the Group B possibly due to a more controlled molding vector ( P < .05). Conclusion: Both methods proved effective in improving the nasal asymmetry, reducing the alveolar cleft gap, and approximating the lips together; but care must be taken when applying the alveolar molding vector in the Dynacleft system.
Background The objective of our study was to derive an objective assessment scale for three-dimensional (3D) qualitative and quantitative evaluation of secondary alveolar bone grafting (SABG) using cone-bone computed tomography (CBCT) in patients with unilateral cleft lip and palate (UCLP).
Methods CBCT scans for pre- and 3-month post-SABG were reviewed for bone volume, height, width, and density of the bony bridge formed in the cleft defect in 20 patients with UCLP. Basic descriptive and principal component analysis was used to extract the various sub-components of the scale. Spearman's correlation was used to check the validity of the scale, and intra-class coefficient (ICC) and Cronbach's α were calculated to establish the reliability and retest applicability of the scale.
Results Each CBCT scan was assessed in five areas: cementoenamel junction (CEJ), root apex, root midpoint, 3 and 6 mm below CEJ, and tabulated in percentiles of 20, 25, 40, 50, 60, and 75 for all the parameters (bone volume, density, and width). These scores were validated when correlated to the scale given by Kamperos et al. Cronbach's α for the domains demonstrated acceptable to excellent internal consistency. The ICC showed good test–retest reliability having a range of scores from 0.89 to 0.94.
Conclusion The proposed scale for the 3D assessment of SABG in patients with UCLP provides gradation for the objective assessment of the bony bridge. This gradation enables the qualitative and quantitative assessments of the bony bridge, thus allowing each clinician to judge SABG more conclusively.
