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.

Palate Repair

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.

Objective: To evaluate the dental arch relationships for a consecutive series from Goteborg, Sweden, who had delayed hard palate closure. Design: Retrospective study. Setting: Sahlgrenska University Hospital, Goteborg, Sweden. Patients: The dental study models of 104 consecutive unilateral cleft lip and palate subjects. The study cohort was born between 1979 and 1994. Longitudinal records were available at ages 5 (n = 94), 10 (n = 97), 16 (n = 59), and 19 years (n = 46). Five assessors rated models according to the GOSLON Yardstick on two separate occasions each. Interventions: These patients had been operated upon according to the Goteborg protocol of delayed hard palate closure (at age 8 years). Results: 85% of subjects were rated in groups 1 and 2 (excellent or very good outcome), 12% were rated in group 3 (satisfactory), and 3% were assigned to group 4 (poor). No patients presented in Group 5 (very poor). Weighted kappa statistics for double determination of Yardstick allocation for five assessors demonstrated values between .65 and .90 for interrater agreement (good/very good) and between .70 and .90 for intrarater agreement (very good). Conclusions: Delayed hard palate closure as practiced in Goteborg since 1979 has produced the best GOSLON Yardstick ratings in a consecutive series of patients ever recorded worldwide, since the Yardstick was first used in 1983. However, it is noteworthy that a new protocol has been introduced in Goteborg since 1994, in which hard palate closure is done at 3 years due to concerns regarding speech.

Objective: This study aims to assess occlusal relationships and frequency of oronasal fistula at 5 years of age following 2 hard palate closure techniques and to compare results. Design: Retrospective longitudinal study. Setting: Institutional study. Patients: Study patients included 57 patients with nonsyndromic complete unilateral cleft lip and palate who were consecutively treated. All patients underwent our early 2-stage protocol for palatoplasty, which consisted of soft palate plasty at 1 year of age and hard palate closure at 1.5 years of age. Twenty-nine patients underwent hard palate closure using vestibular flap (VF group) technique (2009-2011) and 28 patients underwent conventional hard palate closure with local palatal flap (LPF group) technique (2006-2008). Main Outcome Measures: Occlusal relationships were assessed with 5-year-olds’ index, and frequency of oronasal fistula was investigated. Results: Average 5-year-olds’ index scores for VF and LPF groups were 3.11 and 3.57, respectively ( P < .001). Oronasal fistula occurred in approximately 7% of patients in the VF group and in 18% of patients in the LPF group. Conclusion: Hard palate closure with VF technique may provide better occlusal relationships at 5 years of age than does conventional local closure with the LPF.

Dental Arch Relationship

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