The aim of this study was to measure and compare the dimensions of the dental arches on three-dimensional digital study models in children with and without cleft lip and palate before the primary surgery. The sample consisted of 223 digital models of children aged 3-9 months, divided into 5 groups: without craniofacial deformities, unilateral and bilateral incomplete cleft lip and alveolus, unilateral and bilateral complete cleft lip and alveolus, unilateral cleft lip and palate, and bilateral cleft lip and palate. Dental casts of the maxillary dental arches of the children were used. The dental casts underwent a process of scanning through 3D scanner and the measurements used for the correlation among groups were made on the scanned images. Statistical analysis was performed by t test and ANOVA followed by Tukey test. The results showed that the intercanine distance and anterior cleft width was wider in children with unilateral cleft lip and palate. The intertuberosity distances and posterior cleft width was wider in children with bilateral cleft lip and palate among the groups. Children with cleft lip and palate before the primary surgery had wider maxillary arch dimensions than the children without cleft lip and palate.

Objective To verify the effects of rapid maxillary expansion performed after secondary alveolar bone graft in one patient. Setting Department of Orthodontics of the Hospital for Rehabilitation of Craniofacial Anomalies, University of Sao Paulo. Patient(s) The patient had bilateral cleft lip and palate, had already had a bone graft, and showed a relapsing maxillary constriction in need of correction. Intervention A fixed dental-mucous-bone-supported expander corrected the maxillary constriction. Main Outcome Measure(s) Measurements were obtained from dental casts, including transverse dimensions (intercanine distance [IC], interfirst premolar distance [IP], and interfirst molar distance [IM]) and measurements of the grafted area (interfirst premolar/central incisors [IPI] and interfirst premolar/canine [IPC]) to observe the changes. Clinical and radiographic analyses were done through direct view. Results The occlusal radiograph of the maxilla after expansion showed opening of the intermaxillary suture in the premaxillary area, which was clinically confirmed by the diastema between the maxillary central incisors. No radiographic alteration was observed in the grafted area. The transverse measurements of the dental casts (IC, IP, and IM) showed a significant increase. The measurements of the teeth adjacent to the grafted area, IPI and IPC, increased. Conclusions The orthopedic effect of rapid maxillary expansion after bone graft was verified. Nevertheless, additional studies are necessary to define any side effects in patients submitted to bone graft.

Objective To align the protruding premaxilla in infants with bilateral cleft lip and palate (BCLP), an intraoral appliance (i.e., Hotz plate) and an extraoral appliance consisting of a band covering the head and elastics are used as a presurgical orthopedic treatment in our clinic. The aim of this study was to analyze the configuration and position of the premaxilla and the vomer in infants with BCLP and to investigate the factors generating deviation and bending of the vomer and twisting of the premaxilla. Patients Palatal casts were obtained serially from 10 infants with complete BCLP from 1 to 3 months of age. Measurements These casts were automatically measured using a highly accurate contact-type measuring apparatus. After three-dimensional wire frame models generated from the serial casts were automatically superimposed, the magnitude and direction of the shift were calculated. A discriminant analysis was used for investigation of predictor variables generating the twisting or bending vomer. Results and Conclusions The vomer was found to be bent in two infants and the premaxilla was twisted in three infants. In the infants whose vomers were bent, the magnitude of the posterior shift of the premaxilla was greater than that of the inferior shift. A discriminant analysis indicated that at 1 month of age, a greater inclination and a smaller deviation of the vomer and a longer distance between the cleft edges of the lateral segments had a tendency to be associated with bending of the vomer or twisting of the premaxilla.

Objective: This study aimed to determine the correlations between the craniofacial morphology and pharyngeal airway volume in patients with complete bilateral cleft lip and palate (BCLP). Design: Retrospective study. Setting: Tertiary hospital. Participants: Twenty-seven patients with complete BCLP and 27 class I control patients, aged 10 to 14 years. Main Outcome Measure: The pharyngeal airway volume and craniofacial morphology were evaluated using cone-beam computed tomography. Measurements were compared between groups and any correlations were identified. Results: A significantly smaller total pharyngeal airway volume (TPV), oropharyngeal airway volume, and upper (UOPV) and lower (LOPV) oropharyngeal airway volume were found in patients with BCLP than in class I control patients, with no difference in the nasopharyngeal volume between groups. Furthermore, the craniofacial morphology measurements of N-Me, S-Go, Or-C, Ptm-C, Me-C, Co-Go, Go-Me, Ptm-Or, N-S-Ar, and Ar-Go-Me significantly differed between the BCLP and control groups (all P < .05). Multiple regression analysis indicated that Ptm-C and Me-C; Ptm-C, Or-C, and Me-C; and Me-C explained 20.3%, 38.9%, and 17.1% of the variations in TPV ( P = .025), UOPV ( P = .002), and LOPV ( P = .018), respectively. Conclusions: Total pharyngeal airway volume, TPV, OPV, UOPV, and LOPV were significantly smaller in patients with BCLP than in class I controls. In patients with BCLP, the maxilla showed inhibited sagittal development and a retrograde position; moreover, the pharyngeal airway volume was weakly associated with the position of the maxilla and mandible relative to the coronal plane.

Objective: Three-dimensional analysis of palate size and shape in 30 patients with complete bilateral cleft lip and palate (BCLPc) at the stage of permanent dentition. Design: Cross-sectional study based on laser scanning. Subjects: Thirty dental casts of boys approximately 15 years old with BCLPc and 28 dental casts of healthy boys of the same age. Interventions: Arched-lip suture with periosteoplasty and push-back of the palate with pharyngeal-flap surgery. Main Outcome Measures: Data on palate height in the 210 defined locations and on palate widths and profile area in 10 transverse sections. Results: The palate in patients with BCLPc was conical and narrower than in control study subjects, much more anteriorly than posteriorly. From the canines posteriorly, the palate was of almost constant height of 10 mm in the midline, being higher than in control study subjects at this location and lower more posteriorly (by 24% to 29% between molars). The area of transverse sections was reduced as compared with control study subjects from the first premolars posteriorly and reached more than 40% between molars. The length of the palate up to the first molars was not changed. Conclusion: BCLPc subjects exhibited narrow, low, and flat palate. Palate size and shape differences indicate a substantial reduction of the space for the tongue.

Objective: To assess the reliability and validity of measurements performed on three-dimensional virtual models of neonatal bilateral cleft lip and palate patients, compared with measurements performed on plaster cast models. Materials and Methods: Ten high-quality plaster cast models of bilateral cleft lip and palate patients were scanned with an LDI-scanner to obtain a three-dimensional virtual model. Linear measurements were performed on the plaster cast models using a digital caliper and also on the three-dimensional virtual model using Viscam RP version 2.1 software. The measurements were performed by two observers on two occasions. Results: Intraclass correlations ranging from .81 to .96 were found for all measurements except the measurement between the constructed reference point pr and reference point i (intraclass correlation = .40). A post hoc procedure in which top-view screen prints of the three-dimensional virtual model were used to perform the measurement between reference points pr and i demonstrated an intraclass coefficient of .90. Conclusions: Three-dimensional virtual models obtained by laser scanning neonatal cast models of bilateral cleft lip and palate patients can be used reliably and validly to perform linear measurements between existing reference points on the surface of the model using Viscam RP version 2.1 software. Measurements between reference points constructed outside the surface of the model cannot be validly performed on the three-dimensional virtual model with the software used in this study. For these measurements, top-view screen prints of the three-dimensional virtual model can be used.

Objective Three-dimensional analysis of palate size and shape in patients with complete unilateral cleft lip and palate (UCLP) at the stage of permanent dentition. Subjects Thirty randomly selected dental casts of boys approximately 15 years old with complete UCLP and 28 dental casts of normal boys of the same age. Interventions All patients underwent lip repair according to Tennison with primary periosteoplasty (mean age 8.5 months) and palate repair by pushback and pharyngeal flap surgery (mean age 4.9 years). Main Outcome Measures Data on the palate height in 210 defined locations. Results The palate in patients with UCLP was narrower throughout its whole extent, more anteriorly than posteriorly. From the canines posteriorly, it was also lower, and the difference as compared with controls increased in a posterior direction up to the level of second premolars (up to 30%) and then slightly diminished (to 21% between the first molars). The reduction of area of transverse sections reached 45% between premolars and 39% between first molars. The palate in the anterior portion was highest on the cleft side and in a posterior direction the maximum height of the palate shifted toward the midline and even beyond that line toward the noncleft side. Palatal height did not depend on dentoalveolar arch width. Conclusion The smaller width and height of the palate confirm the substantially reduced space for the tongue in patients with UCLP. The reduction is only slightly larger than in previously examined patients with isolated cleft palate. Palatal vault is asymmetrical, highest anteriorly on the cleft side and posteriorly on the noncleft side.

Nasoalveolar Molding

Objective: Utilize 3-dimensional (3D) photography to evaluate the nasolabial changes in infants with bilateral cleft lip and palate (BCLP) who underwent nasoalveolar molding (NAM) and primary reconstructive surgery. Design: This is a retrospective serial longitudinal study of consecutively enrolled infants from September 2012 to July 2016 with BCLP who underwent NAM before primary lip and nose reconstructive surgery. It included infants who had digital 3dMD stereophotogrammetry records at initial presentation (T1), completion of NAM (T2), and 3 weeks following primary repair (T3). Twelve infants fulfilled the inclusion criteria. 3dMD Vultus software was used to orient images and plot 16 nasolabial points with x, y, z coordinates to obtain the linear and angular measurements. Nasal form changes were measured and analyzed between T1 (0.5 months old), T2 (5 months old), and T3 (6 months old). Intraclass correlation coefficient was performed for intrarater reliability. Averaged data from the 3D images was statistically analyzed from T1 to T2 and T2 to T3 with Wilcoxon tests. Unaffected infant norms from the Farkas publication were used as a control sample. Results: After NAM therapy, statistically significant changes in the position of subnasale and labius superius improved nasolabial symmetry. Both retruded after NAM were displaced downward after NAM and surgical correction with respect to soft tissue nasion. The nasal tip’s projection was maintained with NAM and surgical correction. The columella lengthened from 1.4 to 4.71 mm following NAM. Conclusions: There was a significant improvement in the nasolabial anatomy after NAM, and this was further enhanced after primary reconstructive surgery.
