Objective: To evaluate three-dimensional nasal morphology following primary reconstruction in children with unilateral cleft lip and palate relative to contemporaneous noncleft data.
Design: Prospective, cross-sectional, controlled study.
Setting: Glasgow Dental Hospital and School, Faculty of Medicine, Glasgow University.
Patients And Participants: Two groups of 3-year-old children (21 with unilateral cleft lip and palate and 96 controls) with facial images taken using a three-dimensional, vision-based capture technique.
Methods: Three-dimensional images of the face were reflected so the cleft was on the left side to create a homogeneous group for statistical analysis. Three-dimensional coordinates of anthropometric landmarks were extracted from facial images by a single operator. A set of linear measurements was used to compare cleft and control subjects on right and left sides, adjusting for sex differences.
Results: The mean nasal base width and the width of the nostril floor on right and left sides differed significantly between control and unilateral cleft lip and palate groups. The measurements were greater in children with unilateral cleft lip and palate. The differences in the mean nasal height and mean nasal projection between the groups were not statistically significant. Mean columellar lengths were different between the left and right sides in children with unilateral cleft lip and palate.
Conclusions: There were significant nasal deformities following the surgical repair of unilateral cleft lip and palate.

This study aimed to compare the dimensional alterations of the dental arches and the palate symmetry in patients with unilateral complete cleft lip and palate before and after the performance of primary surgeries by different surgical techniques. The sample was divided into Group 1, G1 - cheiloplasty (Millard technique) and single-stage palatoplasty (von Langenbeck technique); Group 2, G2 - cheiloplasty (Millard technique) and two-stage palatoplasty (Hans Pichler and Sommerlad techniques). The digital dental models were evaluated before (Time 1, T1) and after (Time 2, T2) primary surgeries.

Background: An orofacial cleft significantly impacts the oral health-related quality of life of children and teenagers. Secondary reconstruction is a more complex procedure due to tissue deficiency and scarring. The study aimed to evaluate the use of Pfeifer's wave-line incision method and the rotational flap method in the secondary reconstruction of unilateral lip clefts in patients with unilateral cleft lip and ala nasi aged 5-25 years utilizing anthropometry assessment.

Digital orthodontics has been integrated into NasoAlveolar Molding (NAM) therapy to overcome challenges in the conventional NAM method. This study introduced an individualized Digital NAM (iDNAM) and evaluated the changes in the alveolar ridges and nasolabial morphology after iDNAM treatment. Prospective data were collected from 15 infants with complete unilateral cleft lip and palate who underwent iDNAM therapy.
