Nasoalveolar Molding

The applications of computer-guided technologies for three-dimensional image analysis provide a unique opportunity to quantify the morphological dimensional changes of the face in a practical and convenient way. Symmetry of the nasolabial area is one of the main factors of facial attractiveness as well as being the main objective of the treatment of cleft lip and palate (CLP). Technological advances in computer-guided visualization modes and their applications to three-dimensional stereophotogrammetry provide more practical opportunities and alternatives for facial analysis. Each study, however, uses different protocols for the acquisition and analysis of three-dimensional images. In addition, each study identifies different anthropometric points and calculates linear and angular measurements with overlapping protocols. Therefore, it is appropriate to define a standardization of the three-dimensional analysis of CLP patients to compare the studies of different research centers. The aim of this report is to propose a protocol to standardize the acquisition and analysis of three-dimensional images to evaluate the three-dimensional changes in the nasolabial area in cleft lip and palate patients undergoing pre-surgical nasoalveolar molding (PNAM).

Objective: To quantify 3-dimensional (3D) nasal changes in infants with unilateral cleft lip with or without cleft palate (UCL±P) treated by nasoalveolar molding (NAM) and cheilorhinoplasty and compare to noncleft controls. Design: Retrospective case series of infants treated with NAM and primary cheilorhinoplasty between September, 2012 and July, 2016. Infants were included if they had digital stereophotogrammetric records at initial presentation (T1), completion of NAM (T2), and following primary cheilorhinoplasty (T3). Images were oriented in 3dMD Vultus software, and 16 nasolabial points identified. Patients: Twenty consecutively treated infants with UCL±P. Interventions: Nasoalveolar molding and primary cheilorhinoplasty. Main Outcome Measures: Anthropometric measures of nasal symmetry and morphology were compared in the treatment group between time points using paired Student t tests. Postsurgical nasal morphology was compared to noncleft controls. Results: Nasal tip protrusion increased, and at T3 was 2.64 mm greater than noncleft controls. Nasal base width decreased on the cleft side by 4.01 mm after NAM and by 6.73 mm after cheilorhinoplasty. Columellar length of the noncleft to cleft side decreased from 2:1 to 1:1 following NAM. Significant improvements in subnasale, columella, and nasal tip deviations from midsagittal plane were observed. Treatment improved symmetry of the alar morphology angle and the nasal base–columella angle between cleft and noncleft sides. Conclusions: Three-dimensional analysis of UCL±P patients demonstrated significant improvements in nasal projection, columella length, nasal symmetry, and nasal width. Compared to noncleft controls, nasal form was generally corrected, with overcorrection of nasal tip projection, columella angle, and outer nasal widths.

Objective Three-dimensional (3-D) morphological changes in the maxilla of patients with cleft lip and palate (CLP) have been recorded, mainly using two-dimensional cast analyses. Although these seem to be insufficient, no standardized 3-D method has been developed until now. In this study, accuracy, precision, and validity of a newly developed 3-D digital computer-aided procedure to visualize and metrically analyze the growth of the edentulous maxilla of infants with CLP have been evaluated. Patients The method was applied to 10 infants with complete unilateral CLP. Interventions Consecutive casts of the maxilla (1 week and 3, 6, and 12 months) of each patient were optically measured with a 3-D laser scanner. Following digitizing, the casts were computer reconstructed, aligned, and superimposed using specialized computer software. The distances between the surfaces were measured. Additionally, the surfaces were segmented perpendicular to the alveolar crest, the reference points being C1, C1′, C2, C2′, and I. The volumes of the resulting segments were determined and compared with one another. Results The newly developed analysis enables a visualization of the extent and direction of morphological changes in the maxilla of infants with CLP. With this method it is possible to quantify these changes of the volume of defined alveolar segments. Conclusions The 3-D analysis developed is an ideal tool for the examination of 3-D morphological changes in the edentulous maxilla of patients with CLP. The results will serve as the starting point for a longitudinal study on the efficacy of different methods, not only of presurgical infant orthopedics but also of surgical procedures.

Objective The goal of this study was to use three-dimensional (3D) analysis to characterize the primary facial deformities in children with unilateral cleft lip and palate (UCLP) and then serially analyze the relationships between facial deformities and maxillofacial growth from infancy to adolescence. Participants Twenty-one Japanese subjects with unilateral cleft lip and alveolus (UCLA) and 20 with UCLP who had been operated on and then followed up for more than 15 years were enrolled in this study. Main Outcome Measures Facial cast models taken at cheiloplasty were scanned with a 3D laser scanner. Lateral cephalographs taken when subjects were 15 years of age or older were traced, and linear and angular measurements were calculated. The correlation between primary facial forms and maxillofacial morphology in adolescence was analyzed. Results Three-dimensional analysis showed larger ocular hypertelorism, wider cleft, greater deviation of the columella base, and more severe retruded position of the affected nasal alar base in subjects with UCLP than those with UCLA. Total surface area of the upper lips in subjects with UCLP was significantly smaller than those with UCLA. Correlation analyses revealed that the width of cleft lip, deviation of the columella base, difference of the nose base width, and surface area of the upper lip were statistically correlated with the maxillary length, the anterior position of the maxillary alveolar base, the posterior facial height, and the high angle of the mandible. Conclusion The subjects who had less severe facial deformities and more tissue volume of the upper lips at cheiloplasty showed better maxillofacial growth.
