Abstract
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. DESIGN AND PARTICIPANTS 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.

Abstract
The purpose of this study is to analyze the angular variations within Cupid's bow in patients with unoperated unilateral cleft lip (UCL). Angular features of Cupid's bow were quantified in standardized presurgical photographs of children with UCL by 5 medical professionals specializing in craniofacial anomalies. The peaks and valley of Cupid's bow were identified. A cleft side (CSA) and a noncleft side angle (NCSA) were delineated and measured by each expert. The data was pooled, and the angles were analyzed for symmetry. Cupid's bow asymmetry was defined as a difference between NCSA and CSA ≥3°. Of the 37 patients studied, 29 were found to have asymmetry of Cupid's bow with an average angle difference of 8.0° (95% CI: 6.6°-9.5°). Within this group,15 patients were found with acute asymmetry and 14 with obtuse asymmetry. Geometric analysis was performed on an example of a patient with acute asymmetry to demonstrate how correction of asymmetry can be considered during surgical repair. There is an asymmetry that exists in the Cupid's bow of a significant number of patients with unoperated UCL. This finding not only adds to our understanding of UCL but may also have important implications when selecting the method/technique of surgical repair.

Abstract
OBJECTIVE Objective measurement of pre-operative severity is important to optimize evidence-based practices given that the wide spectrum of presentation likely influences outcomes. The purpose of this study was to determine the correlation of objective measures of form with a subjective standard of cleft severity. DESIGN 3D images were ranked according to severity of nasal deformity by 7 cleft surgeons so that the mean rank could be used as the severity standard. PATIENTS 45 patients with unilateral cleft lip and 5 normal control subjects. INTERVENTIONS Each image was assessed using traditional anthropometric analysis, 3D landmark displacements, and shape-based analysis to produce 81 indices for each subject. MAIN OUTCOME The correlation of objective measurements with the clinical severity standard. RESULTS Lateral deviation of subnasale from midline was the best predictor of severity (0.86). Other strongly-correlated anthropometric measurements included columellar angle, nostril width ratio, and lateral lip height ratio (0.72, 0.80, 0.79). Almost all shape-based measurements had tight correlation with the severity standard, however, dorsum deviation and point difference nasolabial symmetry were the most predictive (0.84, 0.82). CONCLUSIONS Quantitative measures of severity transcend cleft type and can be used to grade clinical severity. Lateral deviation of subnasale was the best measure of severity and may be used as a surrogate of uncoupled premaxillary growth; it should be recorded as an index of pre-operative severity with every cleft lip repair. The correlation of other measures evaluated clarify treatment priorities and could potentially be used to grade outcomes.

The Effects of NAM on the Symmetry of the Face and Maxillary Arch in Babies With Unilateral Cleft. J Craniofac Surg 2023; 34:1618-1624. [PMID: 37307242 DOI: 10.1097/scs.0000000000009469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 04/11/2023] [Indexed: 06/14/2023] Open
Abstract
The study aimed to evaluate the effect of nasoalveolar molding (NAM) therapy through reverse engineering, or its absence, to obtain symmetry of the face and maxillary arch. Twenty-six babies with unilateral cleft lip and palate received treatment with NAM, and 12 babies with unilateral cleft lip and palate without presurgical orthopedics (control group). Patients were molded and photographed in 2-stages: the first month of life (T1/pre) and after the use of NAM/before the cheiloplasty (T2/post). In the digital models, the analyses performed were arch perimeter, arch length, and labial frenulum angle. The photographs allowed us to analyze nasal width, mouth width, columella angle, and nostril area. The results demonstrated that there was an increase in arch perimeter and arch length in control and NAM groups in the T2 period in comparison to T1. Labial frenulum angle was reduced in the NAM group compared to the NAM-T1 and control-T2 periods. Treatment with NAM yielded a reduction in nasal width in the period of T2 compared with T1. Columella angle was enhanced after NAM use in T2 and, was different from control group. The nostril area was reduced in the NAM group in T2 compared with control group. Nasoalveolar molding therapy reduced the labial frenulum angle, contributing to a reduction in the extension of the cleft. The NAM protocol improved facial symmetry, mainly through nasal effects, whereas the absence of orthopedic therapy yielded a commitment to the face and maxillary arch symmetry.

Abstract
The frequency of cleft lip and palate births in Japan is approximately 0.146%. The study aimed to compare the effects of NAM on restoring nasal morphology and improving extraoral nasal morphology in children with cleft lip and palate in the first stage of treatment using 3D imaging and oral model analysis. The subjects were five infants (37.6 ± 14.4 days old) with unilateral cleft lip and palate. The images taken with the 3D analyzer and oral model used for constructing the NAM at the first examination (baseline) and at the completion of the pre-surgical orthodontic treatment (157.8 ± 37.8 days old) were analyzed. The cleft distance was measured at the upper, middle, and lower points on the 3D images. On the model, the cleft jaw width at the maximum protrusion of the healthy and affected sides of the alveolar bone was measured. After the pre-surgical orthopedic treatment, the measured value on the model decreased significantly by a mean of 8.3 mm from baseline, and the cleft lip width narrowed by an average of 2.8 ± 2.2, 4.3 ± 2.3, and 3.0 ± 2.8 mm at the upper, middle, and lower points of the cleft, respectively. Pre-surgical orthopedic treatment using NAM can help narrow the width of the cleft jaw and lip. The sample size is stated at the study limit in the paper.

Abstract
Despite advances in cleft lip treatment, various levels of residual deformity remain after primary repair of cleft lip and palate. The aim of the current study was to compare the stability of short- and long-term postoperative nasal symmetry. This retrospective study included 100 consecutive non-syndromic patients with unilateral complete cleft lip who underwent primary cleft lip repair with follow-up of 5 years. Measurements taken from basal and frontal standard photograph views, obtained preoperatively (T1) and immediately (T2), 1 year (T3), and 5 years postoperative (T4), were analysed. Paired and independent t-tests were applied to assess the significance of differences and relationships, while the inter-class correlation coefficient was used to assess reliability; P < 0.05 was considered significant. The male to female ratio was 1:1; mean age at the time of surgery was 0.43 ± 0.25 years. All patients showed significant improvements following unilateral complete cleft lip repair. All variables measured at T3 revealed a significant relapse when compared to T2, except alar base position, which showed a constant mean across all postoperative follow-ups. Late relapse (T3-T4) was not significant for alar collapse, alar base position, or columellar angle (all P > 0.05). On the other hand, columellar height (P = 0.003), and nostril height (P = 0.038) and width (P = 0.007) showed significant improvements during the late relapse period. In conclusion, the majority of the relapse and changes following the nasal cleft repair occurred within the first postoperative year. However, nasal asymmetries tended to remain stable or reduced during the first 5 postoperative years.

Abstract
In this study, we present a modified technique for primary cleft lip repair with a rotation triangular flap from the cleft lateral side to reconstruct the nasal floor; and evaluate the outcome compared with traditional Millard repair. 40 patients with unilateral cleft lip were included in this research. The patients were divided into 2 groups; 17 patients treated with the Millard technique, and 23 patients treated with the newly modified technique. 14 measurement indexes were employed to evaluate the nose-lip morphology of postoperative patients with UCCL in standardized photographs preoperatively, postoperatively and 1-year follow-up. For lip symmetry, statistical significance was detected in the measurements of the vertical philtral height ratio indicating that the newly modified technique resolve the shortage of lip height on the cleft side 1-year follow-up. (P < .05). In addition, statistical significance was detected in the 1-year postoperative columellar angle, alar width ratio, nostril width ratio, nostril height ratio, and nostril shape (cleft) (P < .05), showing more successful repair of the nose compared with the traditional repair. The modified unilateral cleft lip repair with rotation triangle flap from the cleft lateral side was beneficial in the correction of lip and nasal deformity in and had positive effects on labial symmetry.

Abstract
BACKGROUND Surgical reconstruction of secondary labial deformities associated with isolated unilateral cleft lip (UCL) and/or UCL and palate (UCLP) is challenging. There have been few studies in the literature looking at labial soft tissues quantitatively to assess surgical results. OBJECTIVE To apply a novel computer-aided, 3-dimensional reconstruction technique based on CT scan images to conduct quantitative preoperative and postoperative assessments in patients with UCL/UCLP undergoing surgical revision of secondary labial deformities. METHODS Preoperative and postoperative spiral computed tomographic (CT) scans of the face were performed in 21 randomly selected UCL or UCLP patients, who underwent secondary lip revision surgery. The data was then imported to the SimPlant 11.04 software system. Fixed point-to-point, linear distance, and angles were measured, statistically analyzed and used to assess the effect of the surgery. RESULTS Preoperative measurements showed that the thickness of the upper vermilion at the apex of the Cupid's bow on the affected side was greater than that on the unaffected side. The distance from the apex of the Cupid's bow to the ipsilateral subnasal point of the affected side was smaller than that of the unaffected side (P < 0.05). After surgery, the subjects were rescanned at an average of 9 months, and the curative effects were evaluated. The statistically significant preoperative differences between the affected and unaffected sides were not found postoperatively indicating surgical success. CONCLUSIONS This study demonstrates the utility of a novel method to measure and assess results in the surgical revision of UCL/UCLP patients with secondary lip deformities. This knowledge can aid the surgeon in selection of treatment techniques.

Abstract
The current study was conducted to assess the extent of maxillary arch collapse on the cleft vis-a-vis non-cleft sides in the same individual presenting withunilateral cleft lip and palate (UCLP), using cone-beam computed tomography (CBCT). Thirty-one children (eighteen boys andthirteen girls) with surgically repaired UCLP, who met the inclusion criteria, were selected. Following the acquisition of CBCT scans, fourteen bilateral landmarks were selected. The distance of the bilateral landmark was calculated from the midsagittal plane on the cleft and non-cleft sides for both frontal and axial views. Tracings were done;the data obtained was subjected to statistical analysis;and intra-observer variability was checked with intraclass correlation coefficient (ICC) and two-way ANOVA. Subsequently, the measurements were subjected to paired t-tests at the 95% level of significance with Bonferroni correction. A significant reduction of pyriforme and an alveolar crest above the maxillary 1st molar were discerned in frontal analysis on the cleft side. In the axial view, the zygomatic arch, malar, porion and alveolar crest at the molar region were non-significant, but the alveolar crest at the premolar region (p < 0.004)) was significantly decreased. In the frontal analysis, pyriforme and the alveolar crest above the maxillary 1st molar, and, in the axial view, premolar widths, showed significant reduction when comparing the cleft vis-a-vis non-cleft sides.

Abstract
Background: Concepts regarding cleft lip and palate care vary widely globally, as there is no international consensus. Consequently, institutional surveillance of cleft concepts is essential. In addition to subjective expert rankings, three-dimensional (3D) photogrammetry of the face has become the gold standard for evaluation and objective assessment of facial structures. We evaluated cleft configuration preoperatively to determine the influence thereof on the long-term facial appearance/averageness of unilateral cleft lip patients. Methods: Plaster models of the patient's labio-oral region and nose were made preoperatively, digitized, and cleft configuration assessed (cleft width, cleft-columella angle, nasal projection, heminasal width ratio, transverse lip length, labial height). Between 4 and 12 years after surgery, stereophotogrammetry (3D face scans) were captured to determine the patients' individual facial averageness index (FAI) as a deviation from the population mean, using proportion indices (PIs) of facial landmarks and reference data provided by Farkas and FaceBase. Results: Cleft width (r = 0.77) and columella length correlated strongly with long-term facial averageness (r = 0.52). Decreasing FAI was seen with increasing patient age (r = -0.42), indicating increasing facial averageness. Other cleft properties showed weaker correlations. Cleft alveolus did not have any impact on FAI. Conclusions: The presented method allows objective measurement of facial appearance/averageness as well as preoperative cleft properties. It might be superior to subjective assessments of facial attractiveness/appearance. Objective cleft measurements are strong predictors for future facial averageness. Increasing averageness with growth and age suggests late corrective surgery.

Abstract
OBJECTIVE The study aimed to assess the transverse craniofacial dimensions of patients (age, 7-14 years) with unilateral cleft lip and palate (UCLP), compare these dimensions with those of noncleft individuals, and identify the correlations between the nasal and maxillary transverse widths of patients with UCLP. DESIGN A cross-sectional study. PARTICIPANTS Eighty patients operated on for complete UCLP (UCLP group; 35 girls, 45 boys; median age: 10.7 [7.9-14] years) and 80 age- and sex-matched noncleft individuals (control group; 35 girls, 45 boys; median age: 10.7 [7.3-14] years). INTERVENTIONS Interorbital, bizygomatic, nasal, maxillary skeletal, maxillary molar, mandibular molar, and antegonial width measurements were performed using posteroanterior cephalometric radiographs. Intergroup comparisons were conducted by using the independent samples t-test and Mann-Whitney U test. Correlation between the variables was examined using Pearson correlation analysis. RESULTS The bizygomatic, maxillary skeletal and molar, mandibular molar, and antegonial widths in the UCLP group were significantly less than those in the control group (P < .05). A positive correlation was found between the maxillary skeletal and nasal widths (r = 0.550, P < .001) and between the maxillary molar and nasal widths (r = 0.560, P < .001). CONCLUSIONS In individuals with UCLP, the bizygomatic, maxillary skeletal and molar, mandibular molar, and antegonial widths were significantly less than those in noncleft individuals. As the maxillary skeletal and dental widths presented a positive correlation with the nasal width, a decrease in nasal width must be considered when maxillary constriction is noted.

Abstract
PURPOSE Craniofacial anthropometry is a valuable tool for characterization of facial dysmorphology and evaluation of treatment outcomes. Databases of normal anthropometric ranges are limited for infants. The aim of this study is to establish normative data for craniofacial anthropometric measurements in Caucasian infants. METHODS This is a prospective cross-sectional study including Caucasian infants (≤12 months old) that were recruited from a pediatric medicine practice and Boston Children's Hospital. Infants with craniofacial deformities, trauma or operations were excluded. The sample was stratified by age (in months) into 4 groups: 0 to 3, 3.1 to 6, 6.1 to 9, and 9.1 to 12. Three dimensional (3D) photographs were obtained for all subjects. Forty-five standard anthropometric points were plotted, and 37 measurements were made on the 3D photographs. Two evaluators independently performed all measurements. One examiner repeated the measurements on 25% of the subjects. Intraclass correlation coefficients (ICC) were calculated to assess inter-rater and intra-rater agreement. RESULTS Thirty-three subjects were enrolled in the study. The mean age for the entire sample was 6.3 ± 3.0 months, and 17 subjects (52%) were female. The mean ages (months) for each group were: 1.9 ± 0.7 for group 1 (n = 6); 4.4 ± 0.7 for group 2 (n = 8); 7.5 ± 1.1 for group 3 (n = 11); and 9.9 ± 1.0 for group 4 (n = 8). Descriptive statistics are presented for each group. Inter- and intra-rater agreements were acceptable (ICC >0.6) for 21 anthropometric measurements. CONCLUSIONS This study generated normative craniofacial anthropometric measurements for Caucasian infants. These data can be used in the interpretation of measurements for research studies evaluating craniofacial anomalies in this population.

Abstract
PURPOSE To analyze three-dimensional (3D) nasolabial forms and upper lip surface symmetry after primary lip repair in children with unilateral cleft lip and palate (UCLP). METHODS Subjects were 22 Japanese children with complete UCLP who underwent primary lip repair and were followed-up for 4-6 years. The 3D coordinates of facial landmarks and the angle and radius of the approximate nasal alar circle were calculated. Upper lip surface symmetry was analyzed using histogram intersection. RESULTS The nasal tip and columella base were slightly dislocated to the cleft side, and the midpoint of Cupid's bow shifted to the non-cleft side. The nasal alar and the top of Cupid's bow were reconstructed at the same height, while the approximate nasal alar circle was smaller on the cleft side. The mean value of similarity for upper lip surface symmetry was 0.82; a subject with a higher value had more symmetrical contour lines in the visualized surface image. CONCLUSIONS Postoperative nasolabial forms were almost restored to symmetrical levels, while retaining a small nasal alar. Histogram intersection is applicable as a method for the quantitative evaluation of upper lip surface symmetry in UCLP.

Abstract
BACKGROUND In cleft lip and palate (CLP) patients, the shape of the facial soft tissues shows variety in 3 dimensions (3D). Two-dimensional (2D) photographs and radiographs are insufficient in the examination of these anomalies. The aim of this retrospective study was to examine the soft tissue and craniofacial characteristics of individuals with nonsyndromic unilateral cleft lip and palate (UCLP), bilateral cleft lip and palate (BCLP), skeletal Class III malocclusions, or skeletal Class I malocclusions using 3D facial imaging. MATERIAL AND METHODS The entire study group consisted of a total of 158 patients, aged 8-32 years: 29 of the patients had UCLP, 22 BCLP, 54 had skeletal Class III malocclusions, and 53 had skeletal Class I malocclusions. 3D stereophotogrammetric soft-tissue recordings of all patients were analyzed. ANOVA and the Kruskal-Wallis test were performed to compare the groups. RESULTS Statistically significant differences were observed among the groups in terms of linear, angular, proportional. and volumetric measurements. While nasal differences were not observed in the Class III group, nose and upper-lip deformities were common in the CLP groups. Upper-lip projection was reduced in all 3 groups. In the Class III patients, the lower lip and chin were more prominent than in the other groups. The facial convexity angle was increased in the CLP and Class III groups. The upper-lip volume was decreased in the BCLP, the UCLP, and the Class III groups. CONCLUSIONS Patients with skeletal Class III or CLP anomalies showed significantly different soft-tissue characteristics than the Class I control group. 3D stereophotogrammetric facial imaging is an easy and noninvasive method that can be used in examination and recording of these facial deformities. It is possible to make volumetric measurements using this method.

Abstract
AIM The aim of the present study is to evaluate the effects of nasoalveolar molding (NAM) therapy on nasolabial morphology three dimensionally, and compare the nasolabial linear and surface distance measurements in infants with unilateral cleft lip and palate. METHODS Facial plaster casts of 42 infants with unilateral cleft lip and palate taken at the onset (pre-NAM) and finishing stage (post-NAM) of NAM were scanned with 3dMDface stereophotogrammetry system (3dMD, Atlanta, GA). Nineteen nasolabial linear and surface distance measurements were performed on three-dimensional images. In addition to standard descriptive statistical calculations (means and SDs), pre- and post-NAM measurements were evaluated by paired t test. RESULTS All measurements except lip gap, nostril floor width, and nostril diameter increased between pre-NAM and post-NAM. Nostril and lip height increased significantly on the cleft side (P < 0.05). No differences were present between linear and surface distance measurements except for nasal width measurement. CONCLUSIONS Nasal and lip symmetry improved with NAM. The use of surface distance measurements may be advised particularly for continuous and curved anatomic structures in which circumference differences are expected.

Abstract
BACKGROUND Optimization of care to correct the unilateral cleft lip nasal deformity is hampered by lack of objective measures to quantify preoperative severity and outcome. The purpose of this study was to develop a consensus standard of nasal appearance using three-dimensional stereophotogrammetry; determine whether anthropometric measurements could be used to quantify severity and outcome; and determine whether preoperative severity predicts postoperative outcome. METHODS The authors collected facial three-dimensional images of 100 subjects in three groups: 45 infants before cleft lip repair; the same 45 infants after cleft lip repair; and 45 children aged 8 to 10 years with previous repairs. Five additional age-matched unaffected control subjects were included in each group. Seven expert surgeons ranked images in each group according to nasal appearance. The rank sum score was used as consensus standard. Anthropometric analysis was performed on each image and compared to the rank sum score. Preoperative rank and anthropometric measurements were compared to postoperative rank. RESULTS Interrater and intrarater reliability was excellent (intraclass correlation coefficient, >0.76; Pearson correlation, >0.75) on each of the three image sets. Columellar angle, nostril width ratio, and lateral lip height ratio were highly correlated with preoperative severity and moderately correlated with postoperative nasal appearance. Postoperative outcome was associated with preoperative severity (rank and anthropometric measurement). CONCLUSIONS Consensus ranking of preoperative severity and postoperative outcome can be achieved on three-dimensional images. Preoperative severity predicts postoperative outcomes. Columellar angle, nostril width ratio, and lateral lip height ratio are objective measures that correlate with consensus ratings by surgeons at multiple ages.

Abstract
OBJECTIVE Longitudinal evaluation of asymmetry of the surgically managed unilateral cleft lip and palate (UCLP) to assess the impact of facial growth on facial appearance. DESIGN Prospective study. SETTING Glasgow Dental Hospital and School, University of Glasgow, United Kingdom. PATIENTS Fifteen UCLP infants. METHOD The 3-D facial images were captured before surgery, 4 months after surgery, and at 4-year follow-up using stereophotogrammetry. A generic mesh which is a mathematical facial mask that consists of thousands of points (vertices) was conformed on the generated 3-D images. Using Procustean analysis, an average facial mesh was obtained for each age-group. A mirror image of each average mesh was mathematically obtained for the analysis of facial dysmorphology. Facial asymmetry was assessed by measuring the distances between the corresponding vertices of the original and the mirror copy of the conformed meshes, and this was displayed in color-coded map. RESULTS There was a clear improvement in the facial asymmetry following the primary repair of cleft lip. Residual asymmetry was detected around the nasolabial region. The nasolabial region was the most asymmetrical region of the face; the philtrum, columella, and the vermillion border of the upper lip showed the maximum asymmetry which was more than 5 mm. Facial growth accentuated the underlying facial asymmetry in 3 directions; the philtrum of the upper lip was deviated toward the scar tissue on the cleft side. The asymmetry of the nose was significantly worse at 4-year follow-up ( P < .05). CONCLUSION The residual asymmetry following the surgical repair of UCLP was more pronounced at 4 years following surgery. The conformed facial mesh provided a reliable and innovative tool for the comprehensive analysis of facial morphology in UCLP. The study highlights the need of refining the primary repair of the cleft and the potential necessity for further corrective surgery.

Abstract
OBJECTIVE Rhinoplasty in patients with complete unilateral cleft lip and palate (UCLP) is challenging, and the surgical outcome of the nose is complicated to evaluate. The aim of this study was to assess the nasolabial appearance of patients with UCLP compared with a control group. DESIGN Cross-sectional study. SETTING Riga Cleft Lip and Palate Centre, Latvia. PARTICIPANTS All consecutive 35 patients born between 1994 and 2004 with nonsyndromic complete UCLP were included. Of 35 patients, 29 came for checkup; the mean age was 14.7 years (range 10-18). In the control group, 35 noncleft participants at 10 years of age were included. INTERVENTIONS Nasolabial appearance was evaluated from 3-dimensional images using a 3-dimensional stereo-photogrammetric camera setup (3dMDface System), the results being analysed statistically. RESULTS In UCLP group, a statistically significant difference between cleft and noncleft side was found only in alar wing length ( P < .05). The difference of nasolabial anthropometric distances in the control group between the left and right side was not significant. The difference between the UCLP group and the control group was significant in all anthropometric distances except the lateral lip length to cupid's bow. CONCLUSIONS The nasolabial appearance with acceptable symmetry after cleft lip and reconstructive surgery of the nose was achieved. Symmetry of the nasolabial appearance in patients with UCLP differed from those in the control group. The 3D photographs with a proposed set of anthropometric landmarks for evaluation of nasolabial appearance seems to be a convenient, accurate, and noninvasive way to follow and evaluate patients after surgery.

Abstract
BACKGROUND Optimization of treatment of the unilateral cleft lip nasal deformity (uCLND) is hampered by lack of objective means to assess initial severity and changes produced by treatment and growth. The purpose of this study was to develop automated 3D image analysis specific to the uCLND; assess the correlation of these measures to esthetic appraisal; measure changes that occur with treatment and differences amongst cleft types. METHODS Dorsum Deviation, Tip-Alar Volume Ratio, Alar-Cheek Definition, and Columellar Angle were assessed using computer-vision techniques. Subjects included infants before and after primary cleft lip repair (N = 50) and children aged 8-10 years with previous cleft lip (N = 50). Two expert surgeons ranked subjects according to esthetic nose appearance. RESULTS Computer-based measurements strongly correlated with rankings of infants pre-repair (r = 0.8, 0.75, 0.41 and 0.54 for Dorsum Deviation, Tip-Alar Volume Ratio, Alar-Cheek Definition, and Columellar Angle, p < 0.01) while all measurements except Alar-Cheek Definition correlated moderately with rankings of older children post-repair (r ∼ 0.35, p < 0.01). Measurements were worse with greater severity of cleft type but improved following initial repair. Abnormal Dorsum Deviation and Columellar Angle persisted after surgery and were more severe with greater cleft type. CONCLUSIONS Four fully-automated measures were developed that are clinically relevant, agree with expert evaluations and can be followed through initial surgery and in older children. Computer vision analysis techniques can quantify the nasal deformity at different stages, offering efficient and standardized tools for large studies and data-driven conclusions.

Abstract
OBJECTIVE Restoration of the philtral region following traumatic, cleft, and tumor surgeries is often difficult due to influence of this feature to whole facial beauty. The aim of this study is to investigate the types and measurements of the philtrum and its relationship with the upper lip using a software. METHODS Standard personal photographs of the philtral region were obtained from 200 young adults participated in this study. Linear analyses (the lengths of philtral column and dimple; the philtral width) and angular analyses (apex and central angles of Cupid's bow) were measured as reference points. As for the shape of the philtral column, it was categorized as four distinct types: parallel, triangular, concave, and unclear type. RESULTS The philtral width was 11.37 ± 1.9 mm in males, 10.21 ± 1.80 mm in females. The length of the philtral dimple was 18.16 ± 3.6 mm in males, 18.16 ± 3.6 mm in females. Compared with women, both of the measured average philtral reference lengths displayed a significantly greater value in men. In the meanwhile, compared to women, the angular measurements of Cupid's bow (i.e., the apex and central angle of Cupid's bow) were smaller in men. It was 127.47 ± 12.74° mm in males, 134.1 ± 11.38° mm in females. The triangular and concave types were associated with a substantial fraction in men, whereas the triangular and parallel types were predominant in women. There were significant gender differences in the esthetic rankings of philtral column shapes. CONCLUSIONS These results suggest digitalized reference values relative to the philtral column which may increase the success of the individual reconstructive treatment of the surgical procedures and reduce possible asymmetrical appearance. With the help of certain software, this research has made possible to investigate the ideal parameters of philtral construction in defining the best surgical solution for the patient.

Abstract
PURPOSE The need for a widely accepted method suitable for a multicentre quantitative evaluation of facial aesthetics after surgical treatment of cleft lip and palate (CLP) has been emphasized for years. The aim of this study was to validate a novel computer system 'Analyse It Doc' (A.I.D.) as a tool for objective anthropometric analysis of the nasolabial region. MATERIALS AND METHODS An indirect anthropometric analysis of facial photographs was conducted with the A.I.D. system and Adobe Photoshop/ImageJ software. Intra-rater and inter-rater reliability and the time required for the analysis were estimated separately for each method and compared. RESULTS Analysis with A.I.D. system was nearly 10-fold faster than that with the reference evaluation method. The A.I.D. system provided strong inter-rater and intra-rater correlations for linear, angular and area measurements of the nasolabial region, as well as a significantly higher accuracy and reproducibility of angular measurements in submental view. No statistically significant inter-method differences were found for other measurements. CONCLUSIONS The hereby presented novel computer system is suitable for simple, time-efficient and reliable multicenter photogrammetric analyses of the nasolabial region in CLP patients and healthy subjects.

Abstract
OBJECTIVE Since the 1960s, multiple studies have reported a tendency toward hypertelorism in individuals with nonsyndromic orofacial clefts (OFCs). However, the association between specific cleft types and increased interorbital distance has been inconsistent. Using three-dimensional (3D) surface imaging, we tested whether different forms of clefting showed evidence of increased interorbital distance. METHODS Intercanthal and outercanthal distances and intercanthal indices were calculated from 3D facial surface images of 287 individuals with repaired OFCs. Raw measurements were converted to sex and age-normalized Z-scores. Mean Z-scores for individuals with cleft lip (CL), cleft lip and palate (CLP), and cleft palate (CP) were compared with reference normative values (controls) and one another directly using t tests and analysis of variance. RESULTS The CLP group showed a significant increase in intercanthal width (P = .001) and intercanthal index (P < .001) compared with reference norms. The CP group showed a significant decrease (P < .001) in outercanthal width. The CL group showed no difference from reference norms. The proportion of clinically hyperteloric individuals was generally low but highest in the CLP group (7.4%). Cleft severity had little effect on interorbital spacing. CONCLUSIONS Individuals with CLP exhibited on average a tendency toward mild hypertelorism, driven primarily by an increase in intercanthal distance. This tendency was not seen in CL or CP.

Abstract
OBJECTIVE Quantitative measures of facial form to evaluate treatment outcomes for cleft lip (CL) are currently limited. Computer-based analysis of three-dimensional (3D) images provides an opportunity for efficient and objective analysis. The purpose of this study was to define a computer-based standard of identifying the 3D midfacial reference plane of the face in children with unrepaired cleft lip for measurement of facial symmetry. PARTICIPANTS The 3D images of 50 subjects (35 with unilateral CL, 10 with bilateral CL, five controls) were included in this study. INTERVENTIONS Five methods of defining a midfacial plane were applied to each image, including two human-based (Direct Placement, Manual Landmark) and three computer-based (Mirror, Deformation, Learning) methods. MAIN OUTCOME MEASURE Six blinded raters (three cleft surgeons, two craniofacial pediatricians, and one craniofacial researcher) independently ranked and rated the accuracy of the defined planes. RESULTS Among computer-based methods, the Deformation method performed significantly better than the others. Although human-based methods performed best, there was no significant difference compared with the Deformation method. The average correlation coefficient among raters was .4; however, it was .7 and .9 when the angular difference between planes was greater than 6° and 8°, respectively. CONCLUSIONS Raters can agree on the 3D midfacial reference plane in children with unrepaired CL using digital surface mesh. The Deformation method performed best among computer-based methods evaluated and can be considered a useful tool to carry out automated measurements of facial symmetry in children with unrepaired cleft lip.

Abstract
OBJECTIVE The first part of this study validated an automated computer-based method of identifying the three-dimensional midfacial plane in children with unrepaired cleft lip. The purpose of this second part is to develop computer-based methods to quantify symmetry and to determine the correlation of these measures to clinical expectations. PARTICIPANTS A total of 35 infants with unrepaired unilateral cleft lip and 14 infant controls. INTERVENTIONS Six computer-based methods of quantifying symmetry were developed and applied to the three-dimensional images of infants with unilateral cleft lip before and after cleft lip repair and to those of controls. MAIN OUTCOME MEASURE Symmetry scores for cleft type, changes with surgery, and individual subjects ranked according to cleft severity were assessed. RESULTS Significant differences in symmetry scores were found between cleft types and found before and after surgery. Symmetry scores for infants with unilateral cleft lip approached those of controls after surgery, and there was a strong correlation with ranked cleft severity. CONCLUSIONS Our computer-based three-dimensional analysis of nasolabial symmetry correlated with clinical expectations. Automated processing made measurement convenient. Use of these measures may help to objectively measure cleft severity and treatment outcome.

Abstract
PURPOSE Cleft lip repair is performed in the supine position, tilting the head back under general anesthesia. However, postoperative results are evaluated in the upright position while patients are awake. The purpose of this study was to anthropometrically assess whether nasolabial features of infants with unilateral cleft lip are influenced by posture and anesthesia. MATERIAL AND METHODS Three-dimensional facial images in a preoperative upright position and operating supine position under general anesthesia were captured from 51 consecutive infants with unilateral cleft lip. Twenty-four indirect anthropometric measurements (11 for the nose and 13 for the lip elements) were considered on each infant. RESULTS In the supine position under general anesthesia, alar surface distance was significantly shorter (p < 0.001). Regarding lip measurements, medial lip height of the cleft side and philtrum height were significantly smaller (p < 0.05 and p < 0.05, respectively), whereas vermilion height was greater (p < 0.01). In addition, the cleft width and lip width were significantly broader (p < 0.001 and p < 0.001, respectively) after general anesthesia. CONCLUSIONS Several nasolabial alteration patterns are found after general anesthesia that are presumably attributable to cessation of nasal breathing and the action of muscle relaxation. Surgeons should take these nasolabial changes into account during preoperative planning and postoperative assessment.

Quantitative facial asymmetry: using three-dimensional photogrammetry to measure baseline facial surface symmetry. J Craniofac Surg 2015; 25:124-8.

Abstract
BACKGROUND Although symmetry is hailed as a fundamental goal of aesthetic and reconstructive surgery, our tools for measuring this outcome have been limited and subjective. With the advent of three-dimensional photogrammetry, surface geometry can be captured, manipulated, and measured quantitatively. Until now, few normative data existed with regard to facial surface symmetry. Here, we present a method for reproducibly calculating overall facial symmetry and present normative data on 100 subjects. METHODS We enrolled 100 volunteers who underwent three-dimensional photogrammetry of their faces in repose. We collected demographic data on age, sex, and race and subjectively scored facial symmetry. We calculated the root mean square deviation (RMSD) between the native and reflected faces, reflecting about a plane of maximum symmetry. We analyzed the interobserver reliability of the subjective assessment of facial asymmetry and the quantitative measurements and compared the subjective and objective values. We also classified areas of greatest asymmetry as localized to the upper, middle, or lower facial thirds. This cluster of normative data was compared with a group of patients with subtle but increasing amounts of facial asymmetry. RESULTS We imaged 100 subjects by three-dimensional photogrammetry. There was a poor interobserver correlation between subjective assessments of asymmetry (r = 0.56). There was a high interobserver reliability for quantitative measurements of facial symmetry RMSD calculations (r = 0.91-0.95). The mean RMSD for this normative population was found to be 0.80 ± 0.24 mm. Areas of greatest asymmetry were distributed as follows: 10% upper facial third, 49% central facial third, and 41% lower facial third. Precise measurement permitted discrimination of subtle facial asymmetry within this normative group and distinguished norms from patients with subtle facial asymmetry, with placement of RMSDs along an asymmetry ruler. CONCLUSIONS Facial surface symmetry, which is poorly assessed subjectively, can be easily and reproducibly measured using three-dimensional photogrammetry. The RMSD for facial asymmetry of healthy volunteers clusters at approximately 0.80 ± 0.24 mm. Patients with facial asymmetry due to a pathologic process can be differentiated from normative facial asymmetry based on their RMSDs.

Abstract
OBJECTIVE Three-dimensional surface imaging is an increasingly popular modality for face measurements in infants with cleft lip and palate. Infants are noncompliant toward producing specific facial expressions, and selecting the appropriate moment of acquisition is challenging. The objective was to estimate amount and spatial distribution of deformation of the face due to facial expression in infants with cleft lip and palate and provide recommendations for an improved acquisition protocol, including a method of quality control in terms of obtaining images with true neutral expression. MATERIAL AND METHODS Three-dimensional surface images of ten 4-month-old infants with unrepaired cleft lip and palate were obtained using a 3dMDface stereophotogrammetric system. For each subject, five surface images judged as representing a neutral expression were obtained during the same photo session. Mean and maximum deformations were calculated. A formalized review was performed, allowing the image exhibiting the "best" neutral expression to be selected, thus decreasing errors due to residual facial expression. RESULTS Deformation due to facial expression generally increased from forehead to chin. The amount of deformation in three selected regions were determined: nose (mean, 1 mm; maximum = 3 mm); cleft region (mean, 2 mm; maximum = 5 mm); chin region (mean, 5 mm; maximum = 12 mm). Analysis indicated that introduction of a formalized review of images could reduce these errors by a factor of 2. CONCLUSIONS The continuous change of facial expression in infants represents a substantial source of error; however, this may be reduced by incorporating a formalized review into the acquisition protocol.

Abstract
INTRODUCTION Facial clefts involve complex abnormalities. The therapy is elaborate, and a critical evaluation of therapeutic outcome is required. Our study analyzed the lip and nose deformities associated with unilateral clefts in a prospective longitudinal study. MATERIAL AND METHODS A total of 33 patients with a cleft lip or cleft lip and alveolus (UCL) and 46 with a cleft lip and palate (UCLP) were treated using a similar concept. Standardized photographs were taken preoperatively (age 0.4-0.52 years) and again aged 4.04-4.59 years. Anthropometric analyses were performed and compared with age-matched normal values. RESULTS Nostril width (UCL = 1.01, UCLP = 1.03) and nostril floor width (UCL = 1.02, UCLP = 1.04) were almost symmetric. Nasal tip angles were normalized by surgery. Upper labial height improved, but remained slightly reduced (-4% to -6%). Upper vermillion length was increased (15-17%), and vermillion width was reduced (-12% to -13%) postoperatively. A significantly flatter nostril axis inclination persisted, especially on the affected side (UCL: 37.5°; UCLP: 38.5°), when compared with normal values (53.8°). CONCLUSION Most cleft irregularities were almost eliminated by therapy; however, the outcome is still not satisfactory for some parameters. The rehabilitation of patients with clefts remains a considerable surgical challenge. Facial anthropometric assessment must play an important role in order to detect and overcome therapeutic shortcomings.

Abstract
Objetivo avaliar a mudança do ângulo columelar que ocorre após cirurgia de correção para fissura labial. Métodos o estudo foi observacional de caráter descritivo e de corte transversal. Foram avaliadas crianças no primeiro e segundo ano de vida, portadoras de fissura labial unilateral de ambos os sexos, que foram submetidas a cirurgia para correção da fissura. A pesquisa teve um total de 11 crianças participantes. Foi examinada a região nasal e lábio superior da criança e identificados os pontos antropométricos pronasal, subnasal e glabela. Em seguida, foi realizada fotografia para análise fotogramétrica. Foram realizadas fotos no preoperatório e cerca de 4 meses após a cirurgia. As imagens obtidas por fotogrametria foram avaliadas com o programa gráfico Image J,por meio de ferramentas de estudo angular. Resultados a média da medida dos ângulos no pré-operatório foi de 55,41 graus; a média no pós foi de 78,80 graus, percebendo-se uma aproximação ao plano vertical (p<0,0001). Pacientes com fissura lábio-palatina apresentaram variação de 32 graus quando comparadas as medidas pré e pós-operatórias, enquanto que nos pacientes com fissura pré-foramen incompleta e pré-foramen completa foram menores (0,75 e 25 graus respectivamente). Conclusão ocorre verticalização do ângulo columelar após cirurgia de correção da fissura labial. Os pacientes que apresentam maior modificação do ângulo são, justamente, aquelas que apresentam diagnóstico relacionado a deformidades mais complexas.

Abstract
BACKGROUND Surgical and orthodontic treatment of unilateral cleft lip +/- palate can produce dramatic changes in nasolabial form; however, the lack of ideal methods with which to objectively document three-dimensional form limits the ability to assess treatment outcomes. The purpose of this study was to determine the reliability of three-dimensional stereophotogrammetry for anthropometric assessment of the unilateral cleft lip +/- palate deformity in infants before cleft lip repair. METHODS Preoperative three-dimensional images were acquired from 26 consecutive patients with unrepaired unilateral cleft lip +/- palate. Three raters performed indirect anthropometry on each image on two separate occasions, with at least 1 week between rating sessions. One rater performed direct measurements on participants before surgery while in the operating room. Twenty-six linear and angular measurements were considered, and intrarater, interrater, and intermethod reliability were assessed. RESULTS Regarding intrarater and interrater reliability, most measurements had Pearson coefficients greater than 0.75, mean differences less than 0.8 mm, and mean proportional differences less than 0.1. For measurements involving vermilion height, nostril remnants, or Cupid's bow width, Pearson coefficients ranged from 0.3 to 0.75, mean differences ranged from 0.4 to 0.9 mm, and mean proportional differences ranged from 0.1 to 0.3. Regarding intermethod reliability, correlation coefficients ranged from 0.4 to 0.75 for most measurements. The mean differences for nose and lip measurements were less than 1 mm and between 0.8 and 1.3 mm, respectively. CONCLUSION Three-dimensional stereophotogrammetry provides a reliable method for many anthropometric measurements of nasolabial form in infants with unrepaired unilateral cleft lip +/- palate.

Abstract
BACKGROUND AND OBJECTIVE Objective assessment of postsurgical facial asymmetry can be difficult, but three-dimensional (3D) imaging techniques have made this possible. The objective of this study was to assess residual asymmetry in surgically repaired unilateral cleft lip (UCL) and unilateral cleft lip and palate (UCLP) patients and to compare this with noncleft controls. DESIGN Retrospective multicohort comparative study. PATIENTS AND METHODS Fifty-one 10-year-old children with surgically managed UCLP and 44 children with UCL were compared with a control group of 68 ten-year-olds. The 3D facial models at rest and with maximum smile were created using a 3D imaging system. Asymmetry scores were produced using both anatomical landmarks and a novel method of facial curve analysis. RESULTS Asymmetry for the whole face was significantly higher in both cleft groups compared with controls (P < .001). UCLP asymmetry was higher than UCL (P < .001). In cleft patients, the upper lip and nasal rim were the most asymmetric (P < .001 to .05). Control subjects also displayed a degree of facial asymmetry. Maximum smile did not significantly affect the symmetry of the whole face, but it increased asymmetry of the vermillion border and nasal rim in all three groups (P < .001). CONCLUSIONS Despite surgical intervention at an early age, asymmetry remains significant in cleft patients at 10 years of age. Three-dimensional imaging is a noninvasive objective assessment tool that identifies specific areas of the face responsible for asymmetry. Facial curve analysis describes the face more comprehensively and characterizes soft tissue contours.

Abstract
OBJECTIVE This study was undertaken to analyse in detail the morphological features of the philtral dimple and the developmental changes of philtral morphology, including a comparison with patients with a cleft lip. PATIENTS AND PARTICIPANTS Fifty-five normal Japanese adults, seventy-five children and fifteen patients with complete unilateral cleft lip were referred for analysis. DESIGN 3D facial data were acquired with a non-contacting laser scanner. We calculated the desired linear and angular components, defining the features of the philtrum with analysing software. RESULTS The philtral dimple was morphologically expressed by the two different deepest points in the horizontal and sagittal sectional view, respectively. These decreased with age and did not show any correlation. In contrast, philtral measurements on the X-Y coordinates increased during the course of development. Most of the linear and angular variables in the patients with the cleft lip had exhibited greater values than the normal subjects, reflecting the deformed philtral morphology. CONCLUSIONS To obtain an optimally natural philtral construction accompanied by a symmetrical lip in cleft surgery, it is critical to take into consideration both the geometric features of the philtral depth and age-appropriate morphological features of the philtrum as objective criteria.

Abstract
The aim of this study was to develop a reference frame for three dimensional (3D) facial soft tissue growth analysis in children and to determine its reproducibility. Two observers twice placed the reference frame on 39 3D-stereophotogrammetry facial images of children with orofacial clefts and control children. The observers' performances were analyzed by calculating mean distance, distance variability, and P95 between the same facial surfaces at two different time points. Correlations between observers were analyzed with Pearson's correlation coefficient. The influence of presence of a cleft, absence of one ear in the photograph, and age on the reproducibility of the reference frame was checked using Student's t test. Results of intraobserver comparisons showed a mean distance of <0.40 mm, distance variability of <0.51 mm, and P95 of <0.80 mm. For interobserver reliability, the mean distance was <0.52 mm, distance variability was <0.53 mm, and P95 was <1.10 mm. Presence of a cleft, age, and absence of one ear on the 3D photograph did not have a significant influence on the reproducibility of placing the reference frame. The children's reference frame is a reproducible method to superimpose on 3D soft tissue stereophotogrammetry photographs of growing individuals with and without orofacial clefts.

Abstract
Cranial asymmetries due to nonsynostotic deformation of the skull have been reported with increasing frequency during the last decade. Conservative approaches using helmets and physiotherapy have been shown to be effective in their treatment. Traditionally, documentation has been carried out using anthropometric caliper measurements. The present study evaluates the use of a new three-dimensional photographic system in the improved validation of changes in head deformities. This prospective analysis introduces a new technique for digital anthropometric measurement. The study series comprised 181 children with nonsynostotic head deformities. Three-dimensional photographs were obtained before and after treatment with an orthotic helmet device. The oblique head diagonals and head width and length were measured from three-dimensional photographs using 3dMD customer software. The cranial vault asymmetry index, cranial vault asymmetry, and cranial index were compared before and after treatment. The measurements obtained on three-dimensional images were able to demonstrate significant improvement in early infant cranial deformity after treatment with an orthotic helmet. The cranial vault asymmetry index in plagiocephaly was reduced by 7.16%, and cranial vault asymmetry was reduced by 0.86 cm. The cranial index in brachycephaly decreased by 7.32%. In children with combined plagiocephaly and brachycephaly, the cranial vault asymmetry index improved by 5.77%, cranial vault asymmetry improved by 0.71 cm, whereas the cranial index changed by 5.48%. Three-dimensional photogrammetry can support treatment control in patients with deformational plagiocephaly. This new technology offers several advantages such as easy acquisition of images, detection of landmarks without patient movement, repeatable measurements without patient discomfort, and the opportunity for unbiased evaluation.

Abstract
AIM The aim of this study was to compare the clinical facial soft tissue measurements with the measurements of facial plaster cast, three-dimensional scanned facial plaster cast, 3-dimensional digital photogrammetrical images, and three-dimensional laser scanner images. MATERIALS AND METHODS Three-dimensional facial images of 15 adults were obtained with stereophotogrammetry and a three-dimensional laser scanner. Facial models of subjects were obtained using silicone impression and were scanned. Landmarks were marked on the subjects and plaster casts, digitized on three-dimensional models, and measured in Mimics 12.0 software (Materialise's Interactive Medical Image Control System, Leuven, Belgium). RESULTS No statistically significant differences were found between all three-dimensional measurement methods in mouth width, philtrum median height, and nasal width. Comparison of clinical measurements with facial plaster cast measurements revealed that philtral width, nasal tip protrusion, and right lip and nostril heights were wider and longer in clinical measurements than in facial plaster cast measurements. Comparison of clinical measurements to the laser scanned and stereophotogrammetric model measurements revealed that philtrum lateral and lip heights and philtral width were significantly different between methods. When laser scanned and stereophotogrammetric measurements were compared, significant differences were observed in lip and nostril heights. CONCLUSIONS Facial impression may be problematic owing to the depression caused by the impression material especially on the tip of the nose. Laser scanning is not sensitive enough to visualize the deeper indentations such as nostrils. Stereophotogrammetry is promising for three-dimensional facial measurements and even will be better when color identification between mucocutaneous junctions of the lip region is achieved.

Abstract
OBJECTIVE To evaluate lip scarring and the three-dimensional (3D) lip morphology following primary reconstruction in children with unilateral cleft lip and palate (UCLP) relative to contemporaneous noncleft data. DESIGN Retrospective, cross-sectional, controlled study. SETTING Glasgow Dental Hospital and School, University of Glasgow, U.K. PATIENTS AND PARTICIPANTS Three groups of 10-year-old children: 51 with UCLP, 43 UCL (unilateral cleft lip), and 68 controls. METHODS Three-dimensional images of the face were recorded using stereo cameras on a two-pod capture station, and 3D coordinates of anthropometric landmarks were extracted from the facial images. A novel method was applied to quantify residual scarring and the associated lip dysmorphologies. The relationships among outcome measures were investigated. RESULTS Residual lip dysmorphologies were more pronounced in UCLP cases. The width of the Cupid's bow was increased due to lateral displacement of the christa philteri left (cphL) in both UCL and UCLP patients. In the upper part of the lip, the nostril base was significantly wider in UCLP cases when compared with UCL cases and controls. Scar redness was more pronounced in UCL than in UCLP cases. No relationship could be identified between lip scarring and other measurements of lip dysmorphology. CONCLUSIONS Stereophotogrammetry, together with associated image analysis, allow early detection of residual dysmorphology following cleft repair.

Implementing a superimposition and measurement model for 3D sagittal analysis of therapy-induced changes in facial soft tissue: a pilot study. J Orofac Orthop 2010; 71:221-34. [PMID: 20503004 DOI: 10.1007/s00056-010-9932-z] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2009] [Accepted: 02/17/2010] [Indexed: 10/19/2022]
Abstract
AIM 3D digital surface photogrammetry is an objective means of documenting the quantitative evaluation of facial morphology. However, there are no standardized superimposition and measurement systems for surveying soft tissue changes. The aim of this study was to present a superimposition and measurement model for three-dimensional analysis of therapy-induced sagittal changes in facial soft tissue and to ascertain its applicability based on the reproducibility of 3D landmark positions. PATIENTS AND METHOD Twenty-nine children were examined (eight with cleft lip and palate, six with cleft palate, eight with Class III malocclusion and seven healthy controls, between 4.1 and 6.4 years). The mean time between examinations was 8.2 months for the patients and 8 months for the control group. Data was acquired with the DSP 400((c))imaging system. A mathematical model with seven superimposition points was developed. Two 3D images, one at the beginning and the other at the end of the examination, were generated. Both images were superimposed ten times. Ten landmarks for evaluating the soft tissue changes were geometrically defined on the superimposition image, put in place ten times, and measured. The landmarks' reproducibility was calculated via statistical intraoperator analysis. Measurement error was identified using the root mean square error (RMSE). RESULTS The superimposition points were easy to locate and the landmarks well definable. All midface landmarks proved to be highly reproducible with an RMSE under 0.50 mm. The lower face landmarks demonstrated good reproducibility with an RMSE under 1 mm. The midface landmarks' precision fell below the range of accuracy, while the lower face landmarks' precision fell within the optoelectronic scanner device's range of accuracy (0.50-1 mm). CONCLUSIONS As an accurate, non-invasive, millisecond-fast, non-ionizing and ad infinitum repeatable procedure, 3D digital surface photogrammetry is very well suited for clinical and scientific application in orthodontics. We developed a reliable superimposition and measurement model with 3D digital surface photogrammetry. This new capturing and measurement system provides a simple means of determining 3D changes in facial soft tissue. Our landmarks proved to be highly reproducible for the midface while revealing good reproducibility for the lower face.

Abstract
AIM Rapid Maxillary Expansion (RME) and Delaire facemask are a well-established treatment method for patients with cleft lip and palate and Class III malocclusion. Several roentgenocephalometric studies on skeletal effects of this therapy are known. However, there are no systematic studies on soft tissue changes. The aim of this study was to analyze three-dimensionally the soft tissue changes in facial morphology of children with cleft lip and palate and Class III malocclusion under therapy with RME and Delaire facemask. PATIENTS AND METHOD A prospective longitudinal clinical trial was undertaken. 29 children between 4.1 and 6.4 years were divided into four groups: eight patients with unilateral cleft lip and palate (group 1), six patients with isolated cleft palate (group 2), eight patients with Class III malocclusion (group 3). The mean treatment period with RME and Delaire mask was 8.2 months. Seven untreated children with no need of orthodontic treatment were chosen as the control (group 4). Two 3D images, one at the beginning and one at the end of the study, were generated with the DSP 400((c)) imaging system. Both images were superimposed ten times and measured ten times. RESULTS We detected significant forward rotation and forward displacement of the soft tissue in the lower midface with the dentoalveolar areas in all patient groups. No significant asymmetric forward displacement of the soft tissue in the maxilla could be verified in the lower or upper midface, not even in the unilateral cleft lip and palate patients. Among the groups, the Class III malocclusion patients showed greater maxillary soft tissue changes. CONCLUSION The RME and the Delaire facemask demonstrated the greatest effectiveness in the lower midface soft tissue in terms of forward displacement and forward rotation in the cleft lip and palate patients, particularly in the Class III patients. The 3D data allowed us to discriminatively interpret the effects of the orthopedic mask on the entire maxillary complex and maxillary alveolar process. In the unilateral cleft lip and palate patients, there was descriptively both symmetric and asymmetric advancement of the midface soft tissue.

Abstract
OBJECTIVE To evaluate nasal morphology, symmetry, and nostril shape in patients with unilateral cleft lip and palate following mixed-dentition alveolar bone grafting. DESIGN Prospective stereophotogrammetric study. SETTING Hospital-based. PATIENTS Thirty-nine patients with a history of repaired unilateral cleft lip and palate who received an iliac crest alveolar bone graft were recruited prospectively to participate in the study. Each patient served as his/her own control. INTERVENTIONS Partial facial impressions of all patients were acquired before and a minimum of 6 months after the alveolar bone grafting procedure. Image acquisition and analysis of the casts constructed from these models were carried out using three-dimensional stereophotogrammetry. MAIN OUTCOME MEASURES Surface-based registrations and linear measurements were performed to assess nasal morphology and nostril shape. A modified Procrustes technique was used to determine the change in nasal symmetry. A two-tailed, paired t test and an analysis of covariance were used to assess statistical significance. RESULTS Significant side-to-side asymmetry exists in the nasal region of patients with unilateral cleft lip and palate, both before and after alveolar bone grafting. No significant changes were observed between pre-alveolar bone graft and post-alveolar bone graft images based on linear measurements, asymmetry scores, and registrations. Gender and surgeon were not significant factors. CONCLUSION Under the conditions of this study, mixed-dentition alveolar bone grafting appears to have no significant long-term effect on nasal morphology, symmetry, or nostril shape.

Abstract
In maxillofacial surgery, digital photographic documentation plays a crucial role in clinical routine. This paper gives an overview of the evolution from analog to digital in photography and highlights the integration of digital photography into daily medical routine. The digital workflow is described and we show that image quality is improved by systematic use of photographic equipment and post-processing of digital photographs. One of the advantages of digital photography is the possibility of immediate reappraisal of the photographs for alignment, brightness, positioning, and other photographic settings, which aids in avoiding errors and allows the instant repetition of photographs if necessary. Options for avoiding common mistakes in clinical photography are also described and recommendations made for post-processing of pictures, data storage, and data management systems. The new field of 3D digital photography is described in the context of cranial measurements.

Abstract
OBJECTIVE To evaluate the clinical application of three-dimensional (3D) imaging for the analysis of a broad variety of cleft lips and to conduct a systematic analysis. DESIGN This was a prospective study using a noncontact 3D laser scanner to acquire the preoperative 3D facial profiles. The data sets were analyzed qualitatively and quantitatively. The data were expressed by ratios and scores. PATIENTS Forty nonsedated patients (1 to 39 years, average age 2.7 years) with unilateral cleft lip, cleft lip and alveolus, or complete unilateral cleft in Cambodia. RESULTS The acquired 3D data sets (mean acquisition time: 2.5 seconds) from facial surfaces were of diagnostic quality in 27 of 40 patients (average age, 14.2 years). In these cases all anatomical structures could be mapped precisely by means of landmark positioning in the range of millimeters. A new method of systematic analysis could be elaborated, allowing for data set expression independent of size and growth factors. In children under age 3, the measuring procedure was of limited value because of motion artifacts and was successful in only 6% (1 of 15) of these patients. CONCLUSION The system offers a solid and precise tool for 3D imaging of the complex cleft lip anatomy in compliant patients and is useful for preoperative cleft assessment and follow-up. However, the application is limited in moving infants or uncooperative adults because of scanning time and acquisition method. The development of motion tracking and faster devices could eliminate motion artifacts.

Abstract
Assessment of surgical outcome in congenital craniofacial malformations is necessary to evaluate treatment efficiency since the results of early surgery are influenced by surgical technique and timing. Available outcome measurements all have their limitations, especially for application in congenital craniofacial malformations. Therefore a new outcome measurement was developed, in which each facial unit is scored in a standardized way. For each facial unit, deformities of shape or contour, malposition and soft tissue involvement were evaluated, besides scoring for specific congenital malformations of that area. The final result was tested on pre- and postoperative photographs of patients with rare facial clefts and reliability and validity were demonstrated. The new developed instrument showed the ability to provide quantification of outcome. Because of its properties it can serve as an instrument to compare outcome between techniques, surgeons and centers in a more objective and standardized way.
