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: 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.

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.

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.

Objective To investigate biomechanical effects of cleft type (unilateral/bilateral cleft lip and palate), facemask anchorage method (tooth-borne and miniplate anchorage), and alveolar bone graft on maxillary protraction. Design Three-dimensional finite element analysis with application of orthopedic force (30° downward and forward to the occlusal plane, 500 g per side). Model Computed tomography data from a 13.5-year-old girl with maxillary hypoplasia. Intervention Eight three-dimensional finite element models were fabricated according to cleft type, facemask anchorage method, and alveolar bone graft. Main Outcome Measure(s) Initial stress distribution and displacement after force application were analyzed. Results Unilateral cleft lip and palate showed an asymmetric pattern in stress distribution and displacement before alveolar bone graft and demonstrated a symmetric pattern after alveolar bone graft. However, bilateral cleft lip and palate showed symmetric patterns in stress distribution and displacement before and after alveolar bone graft. In both cleft types, the graft extended the stress distribution area laterally beyond the infraorbital foramen. For both unilateral and bilateral cleft lip and palate, a facemask with a tooth-borne anchorage showed a dentoalveolar effect with prominent stress distribution and displacement on the upper canine point. In contrast, a facemask with miniplate anchorage exhibited an orthopedic effect with more favorable stress distribution and displacement on the middle maxilla point. In addition, the facemask with a miniplate anchorage showed a larger stress distribution area and suturai stress values than did the facemask with a tooth-borne anchorage. The pterygopalatine and zygomatico-maxillary sutures showed the largest suturai stress values with a facemask with a miniplate anchorage and after alveolar bone grafting, respectively. Conclusion In this three-dimensional finite element analysis, it would be more advantageous to perform maxillary protraction using a facemask with a miniplate anchorage than a facemask with a tooth-borne anchorage and after alveolar bone graft rather than before alveolar bone graft, regardless of cleft type.

Bilateral Cleft Lip

Nasal deformity is associated with congenital cleft lip and palate. Primary rhinoplasty for reconstruction of the nasal deformity at the time of bilateral cleft lip repair is a controversial issue in cleft care due to traditional teaching concerning the potential impairment of nasal growth. This study assessed long-term nasal growth in patients with bilateral cleft lip and palate who underwent primary rhinoplasty by a single surgeon between 1995 and 2002 and reached skeletal maturity (n = 39; mean: 19 ± 2 years). Normal age-, gender-, and ethnicity-matched subjects (n = 52) were enrolled for comparative analyses. Three-dimensional nasal photogrammetric measurements (10 linear, 4 angular, 6 proportional, 1 surface area, and 1 volume parameter) were collected from patients with bilateral cleft lip and palate and normal subjects. Patients who underwent rhinoplasty presented with significantly (all p < 0.05) smaller nasal tip projection and nasal tip angles, but greater values for nasal dorsum length, nasal protrusion, alar width, columellar height, dome height, columellar angle, labiocolumellar angle, nasal tip height ratio, nasal index, alar width/intercanthal distance ratio, and alar width/mouth width ratio compared to normal subjects. There were no differences (all p > 0.05) in nasal height, tip/midline deviation, nasal dorsum angle, dome-to-columella ratio, columella height/alar width ratio, area surface, and volume parameters between the two groups. This study shows that primary rhinoplasty performed in patients with bilateral cleft lip and palate during infancy does not result in deficiency of the nasal dimensions relative to controls.

Objective. To evaluate the three-dimensional ultrasound paper cleft lip and palate deformities in applications in prenatal diagnosis. Methods. 25 cases of cleft lip and palate fetus, 20–32 weeks of gestational age, with the maternal age of 22–44 years, were examined by prenatal ultrasound in our hospital; conventional two-dimensional ultrasound examination was performed after a cleft lip, and the application of three-dimensional ultrasound imaging surface and a transparent imaging showed the alveolar process and the palate of the fetus. Also, the results of two-dimensional ultrasound and postnatal (or after induction) results were compared. Results. Of the 25 cases, there were 6 cases of postpartum induction or simply unilateral cleft lip, 17 cases of unilateral cleft palate, and two cases of bilateral cleft lip palate. There was no significant ( P > 0.05 ) difference of two- and three-dimensional ultrasound detection rate of pure cleft lip; two-dimensional ultrasound cleft palate detection rate was 36.8% (7/19), and three-dimensional ultrasound cleft palate detection rate was 89.5% (17/19). The two methods showed a statistically significant ( P < 0.05 ) difference in the detection rate of cleft palate. Conclusion. Three-dimensional ultrasound can significantly improve the diagnostic accuracy of prenatal cleft palate.
