Objective To evaluate the motion of the face and jaw of patients with cleft lip and palate, facial palsy, and in patients after reconstruction, a motion-analyzing system was developed. The aim of this article was to investigate the accuracy of this system and the possibility of clinical application. Methods Markers of 1 to 2 mm were placed on the face, and motion images were obtained by three digital video cameras controlled by a synchronizer and recorded on digital video tape. The image was processed on a personal computer. The markers were automatically tracked across the image sequences, and their three-dimensional coordinates were then calculated. Main Outcome Measures System accuracy was investigated using a positioning actuator with high accuracy and a known object. In three patients with bilateral cleft lip and palate, lip pursing was analyzed using the aforesaid method. Results and Conclusions The mean differences from the known values to the distances between the tracked sample points and to the mobile distances of the sample points per frame were 0.24 to 0.36 mm and 0.02 to 0.05 mm, respectively. Both results were similar regardless of the mobile speed or direction. In five repeated measurements, the mean differences from the known values as for the distances and the mobile speed ranged from 0.19 to 0.38 mm and from 0.00 to 0.07 mm, respectively. Examination of three patients with bilateral cleft lip and palate indicated the possibility that lip movement could be successfully analyzed using the present system.

ABSTRACT Objective: The purpose of this paper was to describe the prevalence and type of dental anomalies in the primary and permanent dentition in children with a cleft condition at Princess Margaret Hospital in Perth, Western Australia. Materials and Methods: The details of 162 current dental patients extracted from the main dental database through their year of birth for the period 1998–2001 were selected consecutively. Dental records and X-rays were examined by one examiner (WN) and verified by a second examiner (RB) to determine dental development. The mean age of the subjects was 10.8 years with equal numbers of males and females. Subjects were further divided into cleft type; unilateral cleft lip (UCL) and palate, bilateral cleft lip (BCL) and palate, UCL, BCL, and cleft palate. Results: One hundred sixty-two subjects were grouped into 21 categories of anomaly or abnormality. Prevalence rates for the categories were calculated for the overall group and for gender and cleft type. Conclusion: Overall, 94% of patients were found to have at least one dental anomaly, with fifty-six (34%) patients having more than one anomaly or abnormality.

Objective The aim of this study was to investigate the prevalence of caries in South Vietnamese children with a known oral cleft. Setting The children were screened at local dental hospitals in five different cities in southern Vietnam. Participants One hundred fifty-four children aged 4 to 6, 11 to 13, and 14 to 16 years old with a cleft lip, cleft palate, or both were included in the study. Outcome Measurements For every age group, clefts were divided in four types. The dmft/DMFT was specified according to criteria of the World Health Organization (1997). Results The mean number of teeth affected by caries was 9.95 for 4- to 6-year-old children, 2.97 for 11- to 13-year-old children, and 4.93 for 14- to 16-year-old children, respectively. Four- to 6-year-old children with a unilateral or bilateral cleft lip and palate had significantly more caries and a higher dmft (decayed, missing, and filled teeth index) than children of the same age with only a cleft lip or a cleft lip and alveolus. Conclusions Vietnamese children with an oral cleft have high numbers of teeth affected by dental caries, and special attention will be necessary for their oral health.

Objective: To investigate the variation between the non-syndromic cleft lip and/or palate (NSCLP) and non-cleft (NC) subjects in relation to the lip morphology (LM) and nasolabial angle (NLA). Materials and Methods: Lateral cephalogram (Late. Ceph.) of 123 individuals (92 NSCLP [29 = bilateral cleft lip and palate (BCLP), 41 = unilateral cleft lip and palate (UCLP), 9 = unilateral cleft lip and alveolus (UCLA), 13 = unilateral cleft lip (UCL)], and 31 NC) who did not undergo any orthodontic treatment were investigated. By WebCeph, an artificial intelligence- (A.I.) driven software, 2 (two) parameters of LM, namely upper lip to E line (LM-1) and lower lip to E line (LM-2), and NLA analysis was carried out for each individual. Multiple tests were carried out for statistical analysis. Results: The mean ± SD observed for LM-1, LM-2, and NLA for NC individuals were 1.56 ± 2.98, 0.49 ± 3.51, and 97.20 ± 16.10, respectively. On the other hand, the mean ± SD of LM-1, LM-2, and NLA for NSCLP individuals were 4.55 ± 4.23, 1.68 ± 2.82, and 82.02 ± 14.66, respectively. No significant variation was observed with respect to gender and side. NSCLP (different types) and NC individuals showed significant disparities in LM-1 and NLA. Conclusion: It can be concluded that parameters of lip morphology such as LM-1, LM-2, and NLA vary among NSCLP and NC individuals.

Aim This study is a comparison of pharyngeal airways and associated soft tissues of unilateral and bilateral cleft lip and palate patients with the noncleft individuals. Materials and Methods Twenty-four unilateral cleft lip and palate patients (UCLP), 21 bilateral cleft lip and palate patients (BCLP), and 26 noncleft patients (NC) between ages 15 to 17 were included in the study. Eleven linear, 1 angular, and 1 proportional measurements were carried out on pretreatment lateral cephalometric head films of these individuals. Results The nasopharyngeal depths were markedly reduced in BCLP when compared with the NC (P < .001) and UCLP (P < .01) with a significant difference (P < .01) also among UCLP and NC. Minimum space behind the tongue concerning BCLP and UCLP were significantly lower compared to the NC (P < .001 and P < .01, respectively). In pairwise comparison among the clefts, BCLP showed significant (P < .05) narrowing of this distance. Tongue heights and velar lengths were significantly (P < .001) lower in cleft groups compared to the controls. Similarly, the hyoid bone was positioned in a significantly (P < .01) anterior and inferior direction in cleft patients. Comparison of the mean ratio of velar length to nasopharyngeal depth of the three groups revealed significant (P < .001) inadequacies in cleft patients with significantly (P < .05) more severely reduced values in BCLP. Conclusion Pharyngeal airways and involved soft tissues of cleft patients show serious inadequacies compared to controls, with significant diversities among cleft types pertaining to some of the parameters investigated. It should be kept in mind that these variations can influence function in terms of respiration and phonation.

Objective To report the surgical outcomes of secondary alveolar bone grafting with premaxillary osteotomy in a single surgeon cohort of complete bilateral cleft lip and palate patients. Design Retrospective review of 44 consecutive patients using hospital notes and radiographs. Setting Single specialist cleft lip and palate center, UK. Patients Consecutive patients with complete bilateral cleft lip and palate who were being treated with secondary alveolar bone grafting incorporating premaxillary osteotomy. Outcome Measures Assessment of success of bone graft by Kindelan score; canine eruption; closure of fistulae and assessment of morbidity. Results Between January 6, 2000, and August 8, 2013, 44 patients with complete BCLP underwent secondary ABG with a premaxillary osteotomy as a one-stage procedure. The mean follow-up was 7.3 years (range 1.4 to 14.6). Eighty-five percent of ABGs were successful (a Kindelan score of 1 or 2), and canine eruption was 89%. Failure of the ABG occurred in 7%. Fistulae recurrence rate was 11%, all of which were asymptomatic. No premaxillae were devitalized. Conclusion Incorporating a premaxillary osteotomy into the secondary ABG surgical protocol can be a safe technique that gives excellent surgical exposure for fistula repair.

Objective: To visualize and quantitatively analyze facial surface asymmetry following primary cleft lip repair in patients with unilateral cleft lip and palate (UCLP) and to compare this with noncleft controls. Design: Retrospective comparative study. Patients: Twenty-two patients with complete UCLP who underwent primary lip repair from 2009 to 2013 were enrolled in this study. The preserved 3-dimensional (3D) data of 23 healthy Japanese participants with the same age were used as controls. Interventions: All patients had received primary labioplasty in accordance with Cronin triangular flap method with orbicular oris muscle reconstruction. Main Outcome Measures: Shadow and zebra images established from moiré images, which were reconstructed from 3D facial data using stereophotogrammetry, were bisected and reversed by the symmetry axes (the middle line of the face). The discrepancies of the gravity and density between cleft and noncleft sides in 2 regions of interest, facial and lip areas, were then calculated and compared with those of healthy participants. Results: In the UCLP group, the mean discrepancies of gravity on shadow and zebra images were 1.76 ± 0.70 and 2.63 ± 1.72 pixels, respectively, in the facial area and 1.31 ± 0.36 and 3.83 ± 2.08 pixels, respectively, in the lip area. There was a significant difference in the mean discrepancies of gravity and density on zebra images in the lip area between the UCLP and control groups. Conclusions: Our image analysis of digital facial surface asymmetry in patients with UCLP provides visual and quantitative information, and it may contribute to improvements in muscle reconstruction on cleft lip repair.

Abstract Background When evaluating speech in children with cleft palate with or without cleft lip (CP/L), children with known syndromes and/or additional malformations (CP/L+) are usually excluded. The aim of this study was to present speech outcome of a consecutive series of 5-year-olds born with CP/L, and to compare speech results of children with CP/L + and children with CP/L without known syndromes and/or additional malformations (CP/L-). Methods One hundred 5-year-olds (20 with CP/L+; 80 with CP/L-) participated. All children were treated with primary palatal surgery in one stage with the same procedure for muscle reconstruction. Three independent judges performed phonetic transcriptions and rated perceived velopharyngeal competence from audio recordings. Based on phonetic transcriptions, percent consonants correct (PCC) and percent non-oral errors were investigated. Group comparisons were performed. Results In the total group, mean PCC was 88.2 and mean percent non-oral errors 1.5. The group with bilateral cleft lip and palate (BCLP) had poorer results on both measures compared to groups with other cleft types. The average results of PCC and percent non-oral errors in the CP/L + group indicated somewhat poorer speech, but no significant differences were observed. In the CP/L + group, 25 % were judged as having incompetent velopharyngeal competence, compared to 15 % in the CP/L- group. Conclusions The results indicated relatively good speech compared to speech of children with CP/L in previous studies. Speech was poorer in many children with more extensive clefts. No significant differences in speech outcomes were observed between CP/L + and CP/L- groups.
