OBJECTIVE: To three-dimensionally assess differences in craniomaxillofacial skeletal development in patients with operated unilateral cleft lip and palate (UCLP) treated with/without presurgical nasoalveolar molding (PNAM) with a mean age of 5 years.
METHODS: Cone-beam CT radiographs of 30 patients with UCLP who had undergone PNAM and 34 patients with UCLP who did not receive PNAM were analyzed. The data were stored in DICOM file format and were imported into the Dolphin Imaging program for 3D image reconstruction and landmark identification. 33 landmarks, 17 linear and three angular variables representing craniofacial morphology were analyzed and compared by using the Mann-Whitney U tests.
RESULTS: The vast majority of linear variables and 3D coordinates of landmark points reflecting craniofacial skeletal symmetry were not significantly different between the two groups. In terms of craniofacial skeletal development, the PNAM group had a significantly smaller anterior nasal spine offset in the midsagittal plane and a greater maxillary length compared to the non-PNAM group.
CONCLUSIONS: Evaluations performed in early childhood showed that treatment with/without PNAM in the neonatal period was not a major factor influencing craniomaxillofacial hard tissue development in patients with UCLP; moreover, PNAM treatment showed significant correction of skeletal deviation at the base of the nose.
CONCLUSIONS: Follow-up in early childhood has shown that PNAM treatment administered during the neonatal stage does not impede maxillary development and has benefits in correcting nasal floor deviation. It is a viable option for improving nasal deformity in children with unilateral cleft lip and palate.

OBJECTIVE: To identify predictors for long-term relapse of orthodontic therapy in patients with cleft lip and palate (CLP).
METHODS: Patients with uni- and bilateral non-syndromal CLP were followed up at least two years after completion of their orthodontic therapy. Plaster casts of the start of treatment (T1), after completion of treatment (T2), and at follow-up (T3) were measured using the modified Huddart Bodenham Index. Characteristics of multidisciplinary therapy were taken from the patient files. Potentially influencing factors of relapse were investigated using logistic regression analyses and Spearman correlations.
RESULTS: In total 58.07% of the included 31 patients showed a stable treatment outcome at follow-up after an average of 6.9 years. Even if relapse occurred, 61.54% of these patients still showed improvement regarding their occlusion compared to baseline. Predictors for the occurrence of relapse were the severity of dysgnathia at baseline (p = 0.039) and the extent of therapeutic change (p = 0.041). The extent of therapeutic change was additionally a predictor for the extent of post-therapeutic relapse (ρ = 0.425; p = 0.019).
CONCLUSIONS: Patients with CLP benefit from their orthodontic therapy in the long term despite an increased tendency to relapse.
CONCLUSIONS: Results of this long-term study could be used to adapt the treatment concept for patients with CLP and reinforce the significance of a patient-centered orthodontic treatment concept for affected patients.

During secondary alveolar cleft grafting, the use of autogenous cancellous bone harvested from the iliac crest is still considered the gold standard. Due to the risk of donor-site morbidity and excessive graft resorption, alternative grafting materials (e.g. intraoral bone, xenografts) have been tested. Autogenous tooth bone graft (ATB) is a novel material derived from extracted teeth. ATB has successfully been used in pre-prosthetic and periodontal surgery for hard-tissue reconstruction. Seven patients with unilateral cleft lip and palate were treated with ATB, using their own deciduous teeth for grafting. Defects were accessed utilizing a novel split-thickness papilla curtain flap. Cone-beam computed tomography scans were taken prior to and 3 months following cleft surgery to assess graft integration, graft stability, and the volume of the newly formed hard tissues. Hard-tissue gain, as measured at the 3-month follow-up, averaged 0.65 cm3 ± 0.26 cm3. Results showed acceptable graft integration and stability at the 3-month follow-up, with no adverse effects or excessive resorption of the graft. The use of ATB might be a feasible alternative for alveolar cleft grafting. However, long-term studies using a large sample size are required to derive further conclusions.

Introduction Modern treatments still aim to keep the impact of surgical intervention low and the outcome of surgeries as good as a surgeon can. Assessing the long-term nasolabial appearance of patients who underwent cleft lip (CL) repair surgery is one of the methods of evaluating the outcomes of cleft surgery. Methods This is a retrospective cross-sectional descriptive study of data records of unilateral CL patients. The data records of all patients who underwent unilateral CL repair by the reconstructive science unit at Hospital Universiti Sains Malaysia (HUSM) within the first two years of their lives and whose current age is 14 years or above were accessed and analyzed. Results The data records of 50 patients were analyzed, including 13 (26%) males and 37 (74%) females. The surgeons opined that 28% of the patients had an acceptable nasolabial appearance, while there were 10 (20%) patients whose nasolabial appearance was considered unacceptable by the reviewing surgeons. Fifteen (30%) patients were described as having an acceptable lip appearance with secondary nasal deformity, and 11 (22%) patients had an acceptable nasal appearance with secondary lip deformity. There were no surgical modifications or postoperative complications among the patients. None of our variables reported a significant association with long-term nasolabial appearance. Conclusion The long-term evaluation of the nasolabial appearance in individuals with CL following surgical correction significantly improves the service and care provided to patients to achieve optimum results. Although our results showed no relationship between gender, age at operation, type or diagnosis of cleft, and family history and long-term nasolabial appearance, frequent assessments will enhance surgical results.

OBJECTIVE: To compare the perspective of healthcare providers (orthodontists), cleft patients and laypersons in judging nasolabial aesthetics in patients with complete unilateral cleft lip, with or without cleft palate (UCL ± P) using 2 scoring systems.
METHODS: This cross-sectional study was conducted in a tertiary care government hospital.
METHODS: Photographic records of 100 patients with complete UCL ± P from the age group of 5-18 years (mean age-12.2 ± 3.93 years) were included in this study.
METHODS: Photographic records of 100 patients with complete UCL ± P from the age group of 5-18 years were included. A panel of 3 orthodontists, 3 laypersons and 3 cleft patients rated nasolabial aesthetics using 2 scoring systems i.e. Asher-McDade index (AMAI) and Cleft Aesthetic Rating Scale (CARS). Spearman\'s split-half reliability, Intra-class correlation coefficient and Cronbach\'s alpha were computed to measure internal consistency and reliability. Inter-panel agreement between pair of groups was determined by means of Spearman correlation coefficient.
RESULTS: Estimated reliability of CARS for 3 raters in each panel was in moderate agreement for orthodontists and cleft patients (0.849 and 0.810). Good repeatability and agreement were recorded with moderate to high intra-panel reliability for all parameters of both AMAI and CARS. Overall inter-panel agreement was moderate for both AMAI and CARS. Pair-wise inter-panel agreement showed a moderately positive correlation in both scales (AMAI and CARS) by cleft patients and professionals.
CONCLUSIONS: CARS index can be reliably used for assessment of nasolabial aesthetics by cleft patients, professionals and lay persons on 2D facial photographs. Patients were more critical than clinicians and laypersons using both indices (CARS and AMAI) as they are more self-aware and conscious. Thus, a clear communication between clinician and patient regarding expectations, perception and satisfaction with surgical results is strongly recommended.

OBJECTIVE: To assess modelled facial development of infants with unilateral cleft lip (CL) and cleft lip and palate (UCLP) compared to controls up to two years of age.
METHODS: A total of 209 facial images of children (CL: n = 37; UCLP: n = 39; controls: n = 137) were obtained in four age categories (T0 = 0.2-0.5; T1 = 0.6-1.0; T2 = 1.1-1.5; T3 = 1.6-2.0 years) and were evaluated using stereophotogrammetry and geometric morphometry. All patients underwent lip surgery before T0, patients with UCLP underwent palatoplasty (T0, T1 before palatoplasty; T2, T3 after palatoplasty).
RESULTS: In patients with CL, the forehead was significantly retracted (p ≤ 0.001), while the supraorbital and ocular regions were prominent (p ≤ 0.001). The oronasal region appeared convex (p ≤ 0.001). The lower lip and chin were non-significantly protruded. In patients with UCLP, a significantly retracted forehead and prominent supraorbital region were apparent (p ≤ 0.001). A retrusive oronasal region (p ≤ 0.001) was observed in the middle face. The chin was anteriorly protruded (p ≤ 0.01). No progression of deviations was found with increasing age. After the first year, a slight improvement in the morphological features became apparent. The shape variability of the clefts and controls overlapped, suggesting a comparable modelled facial development.
CONCLUSIONS: The facial morphology of individuals with cleft was comparable to the norm. Shape deviation was apparent in the oronasal region, forehead, and chin, which minimised with increasing age even in complete clefts.

Introduction Cleft of the lip and/or the palate is commonly inherited defect which involves cleft of lip and palate. Maxillary second molar inclination has been studied in various malocclusion. Every abnormality in body is compensated to some extend by compensation. Our objectives were to evaluate maxillary second molar inclination in Angle\'s Class I, Class III malocclusion, and unilateral cleft lip and palate (UCLP) patients in transverse plane and to compare variation in maxillary second molar inclination in Angle\'s Class I, Class III malocclusion, and UCLP cases buccopalatally in transverse plane. Material and method Model of 45 subjects were analyzed. The maxillary second molar inclination was measured using aid of protractor fixed on the surveyor. Axis under consideration was the axis along the long axis of the central fossa of maxillary second molar. Various standardization regarding measurement of second molar inclination were set. The maxillary second molar inclination was compared among 3 groups Angle\'s Class I, Class III malocclusion, and UCLP cases. Results Data was analyzed using one-way analysis of variance (ANOVA) and post-hoc Tukey test. There was a significant difference between inclination of maxillary second molar when Angle\'s Class I malocclusion was compared with Angle\'s Class III malocclusion and UCLP cases (p = 0.003 and p = 0.011, respectively). There was not a significant difference between Angle\'s Class III malocclusion and UCLP cases (p = 0.87). Conclusion Amongst Class III patients and UCLP patients the inclination of maxillary second molar had greater buccal inclination. Maxillary second molar correction would alleviate the effect of deleterious force on periodontium and bone generated by malpositioned teeth.

OBJECTIVE: The objective of the study was to assess nasolabial aesthetics in patients with complete unilateral cleft lip, with or without cleft palate (UCL ± P) using two scoring systems.
METHODS: A cross-sectional study conducted in a tertiary care government hospital.
METHODS: Photographic records of 91 patients with complete UCL ± P from the age group of 5-18 years (mean age = 13.2 ± 3.14 years) were included.
METHODS: A panel of three orthodontists with varying experience in cleft management rated nasolabial aesthetics using two scoring systems, that is Asher Mc-Dade index (AMAI) and Cleft Aesthetic Rating Scale (CARS). Intraclass correlation coefficient, Fleiss\' kappa and Cronbach\'s alpha were used to measure the internal consistency amongst three raters and Spearman-Brown formula was used for measuring overall reliability. Time required for assessment of each photograph was compared with ANOVA.
RESULTS: Overall, both AMAI and CARS showed high reliability and outcome assessment with good inter-rater reliability and internal consistency, when used independently by orthodontists having varied experience. Statistically significant difference was present in time taken for assessment of nasolabial aesthetics with CARS index (8.75 ± 1.65 seconds) as compared to AMAI (18.62 ± 3.49 seconds).
CONCLUSIONS: Asher Mc-Dade index and CARS are equally reliable and consistent for the assessment of nasolabial aesthetics in patients with UCL ± P. However, considerably less time was taken for the assessment using CARS index as compared to AMAI. The use of CARS index is recommended for the initial assessment and screening of patients by orthodontists using two dimensional photographs.

UNASSIGNED: To compare dental arch relationship outcomes following 3 different 2-stage palatal repair protocols.
UNASSIGNED: Retrospective, cross sectional.
UNASSIGNED: Three cleft palate centers (A, B, C) in Japan.
UNASSIGNED: Ninety (A: 39, B: 26, C: 25) consecutively treated Japanese patients with complete unilateral cleft lip and palate.
UNASSIGNED: In A, the soft palate and the posterior half of the hard palate were repaired at a mean age of 1 year 7 months. In B, the soft palate and hard palate were closed separately at a mean age of 1 year 6 months and 5 years 8 months, respectively. In C, the soft palate and hard palate were closed at a mean age of 1 year and 1 year 5 months, respectively.
UNASSIGNED: Dental arch relationships were assessed using the 5-Year-Olds\' (5-Y) index by 5 raters and the Huddart/Bodenham (HB) index by 2 raters.
UNASSIGNED: Intra- and inter-rater reliabilities showed substantial or almost perfect agreement for the 5-Y and HB ratings. No significant differences in mean values and distributions of 5-Y scores were found among the 3 centers. The mean HB index scores of molars on the minor segment were significantly smaller in C than those in A and B (P < .05).
UNASSIGNED: There were no significant differences in dental arch relationships at 5 years among the times and techniques of hard palate closure. However, further analysis of the possible influence of infant cleft size as a covariable on a larger sample size is needed.

UNASSIGNED: Evaluate the effects of alternate rapid maxillary expansion and constriction (Alt-RAMEC) protocol on patients with unilateral cleft lip and palate (UCLP) along with maxillary protraction using cone beam computed tomography (CBCT) records and a finite element modeling (FEM) model.
UNASSIGNED: Twenty-five patients (aged 9-13 years) with UCLP having a GOSLON score 3 were selected for this prospective single-arm cohort study after obtaining necessary informed consent. A 9-week Alt-RAMEC protocol using a custom-made fan-shaped expansion screw was initiated, which was followed by 6-month facemask wear. Pre (T1) and posttreatment (T2) records including CBCT were taken and were evaluated for treatment changes in all 3 dimensions using paired t test. Additionally, a FEM model (ANSYS 15.0) using the Alt-RAMEC protocol was also analyzed for the displacement and stress on various craniofacial structures.
UNASSIGNED: Significant forward movement of the maxilla along with clockwise rotation of mandible along with statistically significant increase in lower molar height and upper incisor proclination (P < .05) was observed. CBCT evaluation showed a statistical significant decrease in buccal alveolar bone thickness and increase in molar inclination (P < .05). Finite element modeling analysis highlighted that the maximum displacement occurred at the anterior region with stresses radiating till the anterior nasal spine, zygomatic arch, and sphenoid bone.
UNASSIGNED: Alt- RAMEC protocol combined with facemask protraction can lead to significant maxillary advancement, with some transient decrease in buccal bone thickness noted thereby warranting long-term studies to further assess its effect on the dentofacial apparatus.
