DESIGN: Cross-sectional study.
SETTING: A dental clinic and a general hospital.
PARTICIPANTS: Parents (N = 84) whose children were less than 12 years old with CL/P.
METHODS: Socio-demographic data and clinical characteristics of CL/P were collected. Self-administered validated Malay versions of the stress scale from the Depressive, Anxiety and Stress Scale-42 (DASS-42) and COPE Inventory questionnaires were used. Descriptive statistics and Multivariate Analysis of Covariance were used for data analysis.
RESULTS: The prevalence of stress among parents of children with CL/P was 21.4% [95% confidence interval (12.4, 30.4)]. The most common coping strategies were problem-focused (mean 58.15, standard deviation (SD) 7.75), followed by emotion-focused (mean 54.05, SD 4.78). The adjusted mean score for overall coping strategies was significantly different between stressed and non-stressed parents after adjustment for education, number of children, sex of child with CL/P, and cleft type [F (df) = 4.174 (3,74), P = .009]. There was a significant mean difference between stressed and non-stressed parents for avoidant coping strategies [P = .003]. Problem-focused and emotion-focused coping strategies did not differ after Bonferroni correction.
CONCLUSIONS: Around a fifth of parents caring for children with CL/P experienced stress and avoidant coping strategies were more common among stressed parents. Multi-disciplinary team care should provide social support to parents of children with CL/P.
OBJECTIVE: The aim of this study is to identify the cranial angles, which are associated with Apert, Crouzon, and Pfeiffer syndromes.
METHODS: The cranial computed tomography scan images of 17 patients with SC and 22 control groups aged 0 to 12 years who were treated in the University Malaya Medical Centre were obtained, while 12 angular measurements were attained using the Mimics software. The angular data were then divided into 2 groups (patients aged 0 to 24 months and >24 months). This work proposes a 95% confidence interval (CI) for angular mean to detect the abnormality in patient's cranial growth for the SC syndromes.
RESULTS: The 95% CI of angular mean for the control group was calculated and used as an indicator to confirm the abnormality in patient's cranial growth that is associated with the 3 syndromes. The results showed that there are different cranial angles associated with these 3 syndromes.
CONCLUSIONS: All cranial angles of the patients with these syndromes lie outside the 95% CI of angular mean of control group, indicating the reliability of the proposed CI in the identification of abnormality in the patient's cranial growth.
DESIGN: A descriptive cross-sectional multicenter study based on a study questionnaire was conducted of parents of patients with cleft lip and/or palate.
SETTING: Three centers providing cleft care from different regions in Malaysia: the national capital of Kuala Lumpur, east coast of peninsular Malaysia, and East Malaysia on the island of Borneo.
PARTICIPANTS: Parents/primary caregivers of patients with cleft lip and/or palate.
RESULTS: There were 295 respondents from different ethnic groups: Malays (58.3%), indigenous Sabah (30.5%), Chinese (7.1%), Indian (2.4%), and indigenous Peninsular Malaysia and Sarawak (1.7%). Malay participants reported that attributing causes of cleft to God's will, superstitious beliefs that the child's father went fishing when the mother was pregnant or inheritance. Sabahans parents reported that clefts are caused by maternal antenatal trauma, fruit picking, or carpentry. The Chinese attribute clefts to cleaning house drains, sewing, or using scissors. Cultural background was reported by 98.3% of participants to pose no barrier in cleft treatment. Those from lower socioeconomic and educational backgrounds were more likely to encounter difficulties while receiving treatment, which included financial constraints and transportation barriers.
CONCLUSION: There is a wide range of cultural beliefs in the multiethnic society of Malaysia. These beliefs do not prevent treatment for children with cleft. However, they face challenges while receiving cleft treatment, particularly financial constraints and transportation barriers. Such barriers are more likely experienced by parents from lower income and lower education backgrounds.
DESIGN: Retrospective assessment using the Peer Assessment Rating (PAR) index.
SETTING: Consecutive patients treated by one consultant orthodontist at a tertiary care cleft center.
PARTICIPANTS: One hundred twenty-seven patients with either complete unilateral cleft lip and palate (UCLP) or bilateral cleft lip and palate (BCLP) consecutively treated with fixed appliances.
INTERVENTION: Fixed orthodontic appliance treatment and orthognathic surgery when required.
OUTCOMES: The PAR index assessment was carried out by a calibrated-independent assessor. Treatment duration, the number of patient visits, and data on dental anomalies were drawn from patient records and radiographs.
RESULTS: One hundred two patients' study models were assessed after exclusions. Mean start PAR score for UCLP (n = 71) was 43.9 (95% CI, 41.2-46.6, SD 11.5), with a mean score reduction of 84.3% (95% CI, 81.9-86.7, SD 10.1). The UCLP mean treatment time was 23.7 months with 20.1 appointments. Mean start PAR score for BCLP (n = 31) was 43.4 (95% CI, 39.2-47.6, SD 11.4), with a mean score reduction of 80.9% (95% CI, 76.3-85.5, SD 12.5). The BCLP mean treatment time was 27.8 months with 20.5 appointments.
CONCLUSION: These results compare well with other outcome reports, including those for patients without a cleft, and reflect the standard of care provided by an experienced cleft orthodontist. As with high-volume surgeons, orthodontic treatment for this high need group is favorable when provided by a high-volume orthodontist. These findings may be used for comparative audit with similar units providing cleft care.
DESIGN: A digitally derived 3-dimensional maxillary model incorporating the palatal defect was generated from the patient's existing cone beam computerized tomography data and compared with the scanned cast from the conventional impression for linear dimensions, area, and volume. The digitally derived cast was 3-dimensionally printed and the obturator fabricated using traditional techniques. Similarly, an obturator was fabricated from the conventional cast and the fit of both final obturator bulbs were compared in vivo.
RESULTS: The digitally derived model produced more accurate volumes and surface areas within the defect. The defect margins and peripheries were overestimated which was reflected clinically.
CONCLUSION: The digitally derived model provided advantages in the fabrication of the palatal obturator; however, further clinical research is required to refine consistency.
DESIGN: A retrospective descriptive study.
SETTING: Hospital Universiti Sains Malaysia.
PARTICIPANTS: All patients with congenital facial cleft deformities from 2005 to 2019 were retrieved from the Plastic Surgery OR Registry. All characteristics in interest were individually tabulated and evaluated. Four cases were reviewed and discussed.
OUTCOME: Prevalence of true MCL.
RESULTS: Out of the 494 patients included in the study, only 4 (0.81%) were affected with a median cleft, and the prevalence of true median cleft was hence determined to be 3 (0.61%) among the cleft population.
CONCLUSION: The prevalence of the true MCL is rare which makes it hard to categorize these clefts, and the surgical protocol needs to be established for the definitive treatment.
SEARCH METHODS: Electronic and manual search was done up to October 2017.
ELIGIBILITY CRITERIA: Clinical and observational studies that compared GPP to control; patients without GPP evaluated either before or after the age for secondary bone graft (SBG).
DATA COLLECTION AND ANALYSIS: Studies selection was done by 2 authors independently. Risk ratio and mean difference with 95% confidence intervals (CIs) were calculated using random-effects models.
RESULTS: Thirteen articles were included in the review. All studies were at high risk of bias. Poorer alveolar bone quality was found in the GPP group compared to the SBG group. The pooled data showed a statistically significant increase in the incidence of Bergland type III in the GPP group compared to SBG (risk ratio: 11.51, 95% CI: 3.39-35.15). As for facial growth, GPP group resulted in a more retruded maxillary position (as indicated by "Sella-Nasion-Subspinale" angle [SNA value]) compared to control group by -1.36 (CI: -4.21 to 1.49) and -1.66 (CI: -2.48 to -0.84) when evaluated at 5 and 10 years, respectively. The protocol for presurgical infant orthopedics used in conjunction with the GPP procedure might have affected the results of the alveolar bone and facial growth outcomes.
CONCLUSIONS: Definitive conclusions about the effectiveness of GPP cannot be drawn. Very weak evidence indicated that GPP might not be an efficient method for alveolar bone reconstruction for patients with unilateral and bilateral CLP. Gingivoperiosteoplasty surgery could lead to maxillary growth inhibition in patients with CLP.
DESIGN: Retrospective study.
SETTING: School of Dental Science, Universiti Sains Malaysia.
SUBJECTS: Eighty-four Bangladeshi children with nonsyndromic UCLP who received cheiloplasty and palatoplasty.
MAIN OUTCOME MEASURES: Dental models were taken at 5 to 12 years of age (man: 7.69), and dental arch relationships were assessed using modified Huddart/Bodenham index (mHB) by two raters. Kappa statistics was used to evaluate the intra- and interexaminer agreements, chi-square was used to assess the associations, and logistic regression analysis was used to explore the responsible factors that affect DAR.
RESULTS: The total mHB score (mean [SD]) was -8.261 (7.115). Intra- and interagreement was very good. Using crude and stepwise backward regression analysis, significant association was found between positive history of class III (P = .025, P = .030, respectively) and unfavorable DAR. Complete UCLP (P = .003) was also significantly correlated with unfavorable DAR.
CONCLUSION: This multivariate study suggested complete type of UCLP and positive history of class III had a significantly unfavorable effect on the DAR.
DESIGN: Retrospective observational study.
SETTING: Two regional cleft-referral centers.
MAIN OUTCOME MEASURES: In the current study, 101 pairs of dental models of non-syndromic CUCLP patients were retrieved from hospital archives. Each occlusal relationship from central incisor till the first permanent molars were scored except the lateral incisor. Sum of 10 occlusal relationships in each study sample gave a total occlusion score. The primary outcome was the mean total occlusion score.
RESULTS: According to MHB, a mean (standard deviation) total occlusion score of -8.92 (6.89) was determined. Based on treatment outcome, 66 cases were favorable (grades 1, 2, and 3) and 35 cases were unfavorable (grades 4 and 5). Chi-square tests indicated, difference of cheiloplasty ( P = .001) and palatoplasty ( P < .001) statistically significant. Five variables-gender, family history of cleft, cleft side, cheiloplasty, and palatoplasty-were analyzed with a logistic regression model.
CONCLUSIONS: Final model indicated that cases treated with modified Millard technique (cheiloplasty) and Veau-Wardill-Kilner method (palatoplasty) had higher odds of unfavorable treatment outcome.
DESIGN: Cross-sectional study on nonsyndromic CL±P and noncleft patients.
SETTING: Reconstructive clinic and outpatient dental clinic, Hospital Universiti Sains, Malaysia.
PATIENTS: Blood samples of 96 nonsyndromic CL±P and 96 noncleft subjects.
MAIN OUTCOME MEASURE: Prevalence and association of mutations in TGFβ3 and Jagged2 genes with nonsyndromic CL±P.
RESULTS: Most of the nonsyndromic CL±P patients (53.1%) had left unilateral CLP. There were slightly more females (56.6%) compared with males. The prevalence of the mutations in the TGFβ3 gene was 17.7 (95% confidence interval [CI]: 9.5, 24.5) and in the Jagged2 gene was 12.5% (95% CI: 5.5, 18.5), which was higher compared with the noncleft group. For the TGFβ3 gene, there was no mutation in the coding region in either of the groups. All variants were single nucleotide polymorphisms located within the intronic flanking region. Two variants were identified (g.15812T>G and g.15966A>G) in both nonsyndromic CL±P and noncleft patients. However, the association was not significant (P > .05). Three variants (g.19779C>T, g.19547G>A, and g.19712C>T) were identified in the Jagged2 gene among nonsyndromic CL±P and noncleft patients. Only g.19712C>T showed a significant association with nonsyndromic CL±P patients (P = .039).
CONCLUSION: g.19712C>T might play a crucial role in the development of cleft lip and palate. To the best of our knowledge, this is the first report of the mutation found within intron 13 of the Jagged2 gene among nonsyndromic CL±P Malay patients.
