In a mixed longitudinal study, dental arch relationships of 88 consecutive UCLP patients treated at the Nijmegen Cleft Palate Centre were evaluated using the Goslon Yardstick. On the basis of timing of hard palate closure, the patients were divided into four groups. Mean age of hard palate closure in group A (n = 18) was 1.5 years, in group B (n = 26) 4.6 years and in group C (n = 18) 9.4 years. In group D (n = 26, no patient older than 10 years) the hard palate was still open. Four stages of dental development were distinguished; deciduous dentition, early mixed dentition, late mixed dentition and permanent dentition. Reproducibility of scoring with the Goslon Yardstick was good for all stages of dental development. No differences in dental arch relationships were found between the four groups. In 86% of the cases, the dental arch relationships of UCLP patients treated in Nijmegen were acceptable. Pharyngeal flap surgery had minor unfavorable effects on dental arch relationships.

Objective: The aim of this study was to investigate the relapse tendency in the maxillary dental arch widths in unilateral cleft lip and palate patients with different types of maxillary arch form. Subjects: Thirty-two unilateral cleft lip and palate patients treated by one-stage surgical palatal closure were included. The subjects were divided into three groups according to the types of the maxillary arch forms: group A, symmetrical arch form; group B, collapse of minor segment; group C, collapse of both segments. Methods: Using dental casts obtained at three different times, relapse in the intercanine, interpremolar, and intermolar widths in each group was assessed and differences between groups were investigated. Results: Patients in group A showed stable results in all measurements. Patients in group B showed posttreatment relapse in the intercanine width only, whereas patients in group C demonstrated significant posttreatment relapses in the interpremolar and intermolar widths. Comparison between groups showed more significant relapse in the interpremolar and intermolar widths of group C than in those of group B. Conclusion: The types of the maxillary arch forms in unilateral cleft lip and palate patients might play a stronger role in the stability of the maxillary dental arch widths after orthodontic treatment in patients with collapse of both segments and a severe degree of maxillary narrowness.

Objective: To investigate whether timing of hard palate repair had a significant effect on facial growth in patients with unilateral cleft lip and palate (UCLP). Design: Retrospective longitudinal study. Setting: Sri Lankan Cleft Lip and Palate Project. Patients: A total of 104 patients with nonsyndromic UCLP who had hard palate repair by age 13 years, with their 290 cephalometric radiographs taken after lip and palate repair. Main Outcome Measures: Clinical notes were used to record surgical treatment histories. Cephalometry was used to determine facial morphology and growth rate. Results: Timing of hard palate repair had a significant effect on the length and protrusion of the alveolar maxilla (PMP-A and SNA, respectively) and the anteroposterior alveolar jaw relation (ANB) at age 20 years but not on their growth rates. Conclusion: Timing of hard palate repair significantly affects the growth of the maxilla in patients with UCLP. Late hard palate repair has a smaller adverse effect than does early hard palate repair on the growth of the maxilla. This timing effect primarily affects the anteroposterior development of the maxillary dentoalveolus and is attributed to the development being undisturbed before closure of the hard palate.

Objective To investigate the effects of infant orthopedic treatment and lip adhesion on maxillary growth of patients with bilateral cleft lip and palate (BCLP). Design Prospective longitudinal study. Setting The present study was conducted at the Cleft Lip and Palate Center, Harapan Kita Children and Maternity Hospital, Indonesia, and the Department of Oral and Maxillofacial Surgery, Kyushu University Hospital, Japan. Subjects The study sample consisted of 53 patients with complete BCLP and 10 noncleft patients with other diseases. Patients with BCLP were divided into three groups: H (-), 11 patients treated without Hotz's plate; H (+), 24 treated with Hotz's plate; and LA-H, 18 treated with lip adhesion and Hotz's plate. Methods Serial dental casts were obtained from each BCLP child at the following four time points: first visit, labioplasty, palatoplasty, and 5 years of age. Each maxillary dental cast was scanned, and the linear and angular dimensions were measured. Results and Conclusion Lip adhesion showed a temporary negative effect. In all patients with BCLP, the surgeries affected the growth of the anterior arch width until the age of 5 years. Collapse of the premaxilla following labioplasty in the H (-) group affected the growth of dental arch length until the age of 5 years. Treatment using Hotz's plate prevented collapse of the premaxilla, and the growth of the arch length was comparable to that observed in the noncleft group.

A prospective study was conducted to look for prevalence of cleft lip and palate ina population presenting to a surgical unit in a teaching hospital. Objectives: To see prevalenceof cleft lip and palate alone, lip and palate combined, right or left sided, male to femaledistribution, and possible factors responsible for clefting. Study Design: A prospective study.Setting: Surgical Unit II at Allied Hospital Faisalabad. Period: March 2009 to March 2010 forone year. Materials and Methods: Total 55 patients were treated in year 2009 out of total17900 (0.3 %) patients admitted in all surgical wards and 6508 patients admitted in surgicalunit II (0.8%). Patients were divided into three groups, cleft lip alone (group A), cleft palatealone (group B) and combined cleft lip and palate (group C). Children up to the age of 5 yearswith congenital abnormality were included in study. Results: Out of 6508 patients admitted insurgical unit II 55 patients (0.8%) had cleft lip and palate defect. 55 patients were divided inthree groups. In group A, 32 patients presented with cleft lip alone ( 58.1 % ), 16 ( 29 % ) weremales and 16 ( 29 % ) were females, 21 patients have left sided ( 38 % ), 4 right sided (7.27% )and 7 patients have bilateral ( 12.72 % ) defects. 2 patients (3.63 %) had family history of cleft lipand both were males. In group B, 12 patients ( 21.8 %) had cleft palate alone, 7 patients ( 12.72% ) were males and 5 patients ( 9 % ) were females, 10 patients ( 1.18 % ) had soft palate onlywhile 2 patients ( 3.63 % ) had compete ( hard and soft ) palatal defect. In group C, 11 patients,had cleft lip and palate combined ( 20 % ), 6 patients were males ( 10.9 % ) and 5 patients ( 9% ) were females, 8 patients ( 14.54 % ) had only soft palate defect while 3 patients ( 5.45 % )had complete palatal defect associated with 8 patients ( 14.54 % ) left sided unilateral lip defectand 3 patients ( 5.45% ) had bilateral cleft lip. All patients were operated without any mortality.Ages of mothers at earliest were 16 and 18 years, 3 cousin marriages, ( 5.45 % ) all fathers weresmokers, belonged to poor socio economic families and no history of mother’s exposure toradiation, drug abuse during gestational life. Conclusion: As it is obvious from this study thatall patients belongs to poor socio economics group, and all fathers were smokers, 3 patientsborn in parents who had cousin marriages ( 5.45 % ) 2 patients ( 3.63 % ) with family history,cleft lip and palate are multifactorial congenital abnormalities, runs in families and is influencedby various environmental factors.

ABSTRACT Objective: To compare the mixed dentition incisor and molar overjet, severity of contraction of the dental arch, and the sagittal molar relationship on the cleft side vs the noncleft side in children with repaired complete unilateral cleft of the lip and palate (UCLP). Materials and Methods: Orthodontic records taken prior to orthodontic preparation for alveolar bone grafting were screened to select study casts from patients with nonsyndromic repaired complete UCLP who did not have mandibular skeletal or dental asymmetry. The study sample comprised dental casts from 74 children aged 8.9 ± 1 years. Standardized digital photographs were acquired at 1:1 magnification. A coordinate system was developed using digital image-processing software (Photoshop CS4 and Adobe Illustrator). Incisor and molar overjet, Angle's classification, and arch contraction were recorded. Descriptive statistics, paired t-tests, and kappa statistics were used to compare the cleft and noncleft sides. Results: A negative overjet of −1 to −5 mm was often present at the incisors, with greater frequency and magnitude on the cleft side. Class II molar relation was more frequent on the cleft side (61.1%) than on the noncleft side (47.2%). Significantly greater contraction of the cleft side deciduous canine and deciduous first molar was noted, while the difference was very minor at the first permanent molar. Conclusions: Cleft side maxillary arch contraction was most severe in the deciduous canine and first deciduous molar region and progressively less severe in the posterior region of the arch. A greater frequency and severity of negative overjet and Class II molar relationship was seen on the cleft side.
