ABSTRACT
BACKGROUND: Cleft lip and palate (CLP) are among the most common congenital anomaly that affects up to 33,000 newborns in India every year. Nasoalveolar moulding (NAM) is a non-surgical treatment performed between 0 and 6 months of age to reduce the cleft and improve nasal aesthetics prior to lip surgery. The NAM treatment has been a controversial treatment option with 51% of the cleft teams in Europe, 37% of teams in the USA and 25 of cleft teams in India adopting this methodology. This treatment adds to the already existing high burden of care for these patients. Furthermore, the supporting evidence for this technique is limited with no high-quality long-term clinical trials available on the effectiveness of this treatment. METHOD: The NAMUC study is an investigator-initiated, multi-centre, single-blinded randomized controlled trial with a parallel group design. The study will compare the effectiveness of NAM treatment provided prior to lip surgery against the no-treatment control group in 274 patients with non-syndromic unilateral complete cleft lip and palate. The primary endpoint of the trial is the nasolabial aesthetics measured using the Asher McDade index at 5 years of age. The secondary outcomes include dentofacial development, speech, hearing, cost-effectiveness, quality of life, patient perception, feeding and intangible benefits. Randomization will be carried out via central online system and stratified based on cleft width, birth weight and clinical trial site. DISCUSSION: We expect the results from this study on the effectiveness of treatment with NAM appliance in the long term along with the cost-effectiveness evaluation can eliminate the dilemma and differences in clinical care across the globe.

The aim of this systematic review was to compare the effectiveness of pre-alveolar bonegraft (ABG) orthodontics with no orthodontic treatment for patients with non-syndromic unilateral cleft lip, alveolus and palate. All relevant studies from 1946 to October 30, 2022, were identified using several sources including The Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), LILACS, Scopus, EMBASE, MEDLINE (Ovid) and EPUB ahead of publications and non-indexed citations. Randomized Controlled Trials (RCT) and Controlled Clinical Trials (CCT) were included. POPULATION: Non-syndromic complete unilateral cleft lip, alveolus and palate patients who have had ABG surgery. INTERVENTION: Orthodontics prior to ABG. Comparison: No orthodontic treatment prior to ABG. PRIMARY OUTCOME: Successful eruption of permanent canines. All articles were screened for the title, abstract and full text independently and in duplicate by 2 reviewers. The quality assessment of RCT was performed using Cochrane's risk of bias tool and the CCT was assessed using ROBINS-I tool. Of the 904 studies retrieved in the search, one RCT and one CCT were included. Both studies were judged as high risk of bias. The results from one study showed a statistically significant increase in bone volume and decreased bone defect post-ABG in the orthodontic treatment group. However, there was no difference with respect to other variables. Both included studies were of low quality. There is not enough evidence to recommend orthodontic treatment pre-ABG for patients with complete unilateral cleft lip, alveolus and palate. Future high-quality studies are required to inform patients and clinicians about the effectiveness of pre-graft orthodontic treatment.

OBJECTIVE: To assess the factors influencing the type and timing of Alveolar Bone Grafting (ABG) among cleft centers throughout India. To examine the decision-making criteria for orthodontic treatment and the timing of ABG. DESIGN: Cross sectional survey. METHOD: This survey was based on a convenience-based sample selected from cleft teams across India. The survey was formulated using the SurveyMonkey platform and emailed to 40 cleft teams. The survey included questions on demographics, timing, surgical protocol, orthodontic protocol, radiograph prescription rate, assessment methods for the success of ABG and three scenarios for evaluating the timing of the bone graft. The Chi-squared test was performed to evaluate the difference in opinion between specialists. The inter-examiner reliability was assessed using Kappa statistics. RESULTS: Thirty-five units completed the questionnaire. Most units operate with 1-2 surgeons, with 42.9% of them treating cleft patients for under 5 years. Only 11.4% of centres routinely advised oblique occlusal radiographs for post-surgery evaluation, and 31.4% prescribed CBCT. However, 40% of cleft teams did not perform audits to evaluate the success of ABG, and less than 50% advised radiographs six months post-surgery. Around 26% of centres do not routinely provide orthodontic treatment pre-ABG. The inter-examiner reliability for case scenarios showed poor agreement between the clinicians. CONCLUSION: The survey showed a serious lack of consensus in the ABG treatment among cleft teams in India and emphasises the need for standardised protocols for the treatment of children with cleft palate. There is an urgent need to develop core outcome set in cleft.
