Palatal growth changes in newborns with unilateral and bilateral cleft lip and palate from birth until 12 months after early neonatal cheiloplasty using morphometric assessment

Use of 3D stereophotogrammetry for volumetric analyses and image superimposition of dental arches before and after surgery of individuals with unilateral and bilateral cleft lip and palate

“…This corroborates other studies(Jaklová et al, 2021;Kongprasert et al, 2019; Ambrosio et al, 2018a, Ambrosio et al, 2018bSasaguri et al, 2014). Generally, G3 had a greater inhibition of the parameters evaluated in the anterior region of the palate, because the palatal segments are more susceptible to the lip healing tissue forces.The reduction of the C-C' distance was a common finding in all groups, that is, regardless of the treatment choice.…”

Correlation between cleft width and dental arch symmetry in cleft lip and palate: a longitudinal study

“…The limitation of anterior linear growth on the cleft side was significant and concurs with the findings of previous studies. 8,16,17,19 Cheiloplasty can limit anterior palate development, but not in the posterior region, because of the continuous pressure exerted by the healing tissue on the dental arch. 5,8,16,20 The unilateral growth of the dental arch suggests that both cleft width and treatment protocol influenced palate formation.…”

“…[16][17][18] Anatomic landmarks and linear parameters were used in the dental arch evaluations according to previous studies with children. 8,9,16,19,20 The following parameters were measured: P-P' -Anterior cleft width (straight line between the most anterior points of the alveolar bone crests); M-M' -Middle cleft width (straight line between the points located in the medial region of the palatal segments adjacent to the cleft); U-U' -Posterior cleft width (straight line between the most posterior points of the palatal segments adjacent to the cleft); I-C' -Anterior intersegment distance (between the interincisive point and the primary canine cusp in the smaller bone segment); I-C -Anterior intrasegment distance (between the interincisive point and the primary canine cusp in the greater bone segment); I-T' -Total intersegment distance (between the interincisive point and the tuberosity of the smaller bone segment); I-T -Total intrasegment distance (between the interincisive point and the tuberosity of the greater bone segment); C'-T' -Cleft-side canine tuberosity distance (between the primary canine cusp and the tuberosity of the smaller bone segment); and C-T -Non-cleft-side canine tuberosity distance (between the primary canine cusp and the tuberosity of the greater bone segment). All the parameters were quantified in mm (Figure 1).…”

“…[2][3][4] Cleft lip and palate treatment protocols are targeted at improving quality of life, esthetics, function, and face and palate symmetry. [5][6][7][8] Residual or persistent asymmetry usually occurs after primary plastic surgeries and requires further therapeutic approaches (secondary plastic surgery or orthopedic treatment) for correction of anatomic and/ or functional problems. 5,[9][10][11] Symmetry in individuals with cleft lip and palate has been evaluated in both soft and hard tissues.…”

Dental caries and periodontitis risk factors in cleft lip and palate patients

“…During embryogenesis, oral and maxillofacial areas are developed from frontonasal process, the paired lateral and medial nasal processes, and the paired maxillary processes. Cleft lip (CL) and cleft palate (CP) are two kinds of congenital malformation resulting from unsuccessful embryonic facial fusion processes and usually co-occur in the form of complete unilateral (UCLP) or bilateral (BCLP) cleft lip and palate ( 1 ). Based on their association with specific malformative patterns or their presence as isolated defects, CL/P can be classified as syndromic (SCLP) and non-syndromic, respectively (NSCLP) ( 2 ).…”
