Orthopaedic traction with passive nasoalveolar moulding in a bilateral cleft lip and palate patient - Rediscovering the old.

INTRODUCTION: A 22-day-old male infant presented with complete bilateral cleft lip and palate with prominent premaxillary segment, wide alar base, flat alar domes and no columellar tissue, thus leading to a severe facial deformity. A presurgical nasoalveolar moulding (PNAM) procedure was planned to facilitate an optimal surgical approximation of the cleft and surrounding tissues. METHODS: PNAM was performed on the basis of the hypothesis that 'The palatal shelves continue to grow unabated if adequate relief is provided by wax mock up while preparing the feeding plate'. An intraoral device, which consisted of an acrylic feeding plate, was constructed after adequate wax mock up in the cleft area for passive moulding, along with extraoral traction force through active lip taping. A nasal stent was subsequently attached to lift the nasal domes and lengthen the columella. The changes thus achieved with PNAM were assessed using innovative photographic and model analyses. RESULTS: On completion of PNAM, the qualitative photographic changes showed significant premaxillary setback, columellar lengthening and fullness of alar domes. The quantitative model analysis revealed reduction in the anteroposterior cleft gap by 5 mm and 5.5 mm on right and left sides, respectively. Transverse distance between the two palatal segments reduced by 3.5 mm, 8 mm and 8.5 mm in anterior, middle and posterior regions, respectively. CONCLUSION: Orthodontic intervention performed for 11 weeks by PNAM helped to retract the premaxilla, reduce the cleft gap, improve the arch form, approximate lip segments and distinctly lengthen the columella. Hence, it improved the morphology of the nose by correcting the flattened nasal wings. This aided the surgeon to achieve an optimal surgical repair.

Effects of pre-surgical nasoalveolar moulding on maxillary arch and nasal form in unilateral cleft lip and palate before lip surgery.

OBJECTIVES: To investigate the effects of pre-surgical nasoalveolar moulding (PNAM) on the maxillary arch and nasal form in patients with unilateral cleft lip and palate (UCLP). SETTING AND SAMPLE POPULATION: This is a retrospective case series study. The subjects were infants with complete UCLP who were treated with PNAM (n = 18) at Kagoshima University Medical and Dental Hospital (Japan) between 2006 and 2013. MATERIAL AND METHODS: Maxillary dental casts and facial photographs were taken at the time of the first visit and immediately prior to lip surgery to evaluate the maxillary arch and nasal form changes. The dental casts were scanned with a laser scanner, and changes in the 3-Dimensional coordinates of anatomical landmarks and alveolar cleft width were analysed. Moreover, we investigated the correlation between the changes in the maxillary alveolar arch and nasal form. RESULTS: Regarding the maxillary alveolar arch form, the anterior points of the major segment had moved significantly to the cleft side just prior to the time of lip repair, and the alveolar cleft width was significantly decreased. For nasal form, the inclination and displacement of the columella were significantly improved. The improvement of columella inclination was moderately correlated with the posterior movement of the anterior points of the major segment. CONCLUSIONS: These findings indicate that PNAM for infants with UCLP enhanced symmetry in the maxillary alveolar arch and nasolabial form. In addition, the posterior movement of the anterior points of the maxillary alveolar arch was correlated with the improvement of columella deformation.
