“…Development of children with facial clefts has been studied extensively, and several researchers report slowed tempos of bone development (Bowers, 2011; Batwa et al, 2018), and dental maturation is delayed (Ranta, 1986; Mitsea and Spyropoulos, 2001), as well as somatic growth (Drillien et al, 1966; Ranalli and Mazaheri, 1975). Moreover, tooth size is diminished (Sofaer, 1979; Antonarakis et al, 2013) because enamel and dentin have virtually no reparative ability, so they forever reflect their environment during formation.…”

Objective: To test for systematic age changes in cleft children based on dental age. Design: Retrospective case–control longitudinal study. Setting: One orthodontic solo practice. Patients: Nonsyndromic, complete cleft lip and palateCLP cases, either unilateral or bilateral (102 children; 370 radiographs), between 4 and 16 years of age. Interventions: Children were treated with a team approach, but only orthodontic radiographs were studied. Main Outcome Measure: The principal outcome measure was dental age of the cleft cases compared to a sex-specific sample of phenotypically normal children (1107 children), from the same geographical region. Multiple panoramic radiographs taken during the course of orthodontic treatment were examined to track patterns of dental age as children matured. Analysis used linear mixed models primarily testing for sex, cleft type (unilateral, bilateral), and hypodontia differences. Initial expectation was that cleft children would exhibit delayed dental ages from postnatal stressors and would become more deviant with maturity. Results: In childhood (4-6 years), both sexes were significantly delayed ( P < .001), but dental age normalized around 8 to 10 years. Boys experienced faster maturation thereafter than girls ( P < .001). Only trivial differences occurred between unilateral CLP and bilateral CLP samples.Hypodontia further depressed maturation rates ( P < .001). Dental age improved in a decidedly curvilinear fashion ( P < .001), with greater change at earlier ages. Conclusions: This report agrees with other contemporary studies, showing childhood catch-up. Older studies observed that clefting caused significant delays that worsened with growth. This potential “seachange” suggests better recovery and quicker normalization of children with clefts, perhaps due to improved management.

“…Nevertheless, the growth spurt of these children should be awaited before conclusive results are formed concerning the measured cephalometric values regarding sagittal growth of the skeleton, since the results in patients in mixed dentition show a lot of variability. Regarding this concept, researchers should be aware of the fact that the end of growth in cleft children is later than in healthy noncleft children [24] .…”

Aim: The purpose of this study was to ascertain the effect of surgical procedures and their timing on maxillofacial growth in unilateral cleft lip and palate (UCLP) patients through a systematic literature review. Methods: In December 2019, a search was conducted in PubMed and Web of Science on the basis of the keywords: "UCLP", "maxillofacial growth" and "facial growth", complemented by a hand search. Results: Eleven articles were included. An important finding was the wide range of treatment protocols. Eight studies performed a multistage procedure, whereas three studies applied a simultaneous repair of cleft lip, palate, and alveolus in a single surgical session. The findings in these articles were based on cephalometric measures. Comparative tables were constructed regarding method of study and time and technique of closure. Conclusion: The results of the articles were conflicting, and it was clear that more research on this subject is necessary. Overall, most studies agreed on the important factor of palatoplasty in maxillofacial growth. The most common finding was a retrusive maxillary growth in comparison to a noncleft control group. This was illustrated by a negative effect on A-point-nasion-B-point. A lot of discussion remains on the effect of lip closure. However,

“…It has also been found that children with UCLP have delayed skeletal maturity. 11,31,32 Whether which may indicate that a link is present between the sella turcica and maxillary and mandibular growth. This however remains to be elucidated.…”

“…Bowers et al 16 found that children with UCLP tend to be shorter in stature. It has also been found that children with UCLP have delayed skeletal maturity 11,31,32 . Whether the dimensions of the sella turcica may vary in relation to the function of the pituitary gland remains an open question.…”

Objective: To use morphometric methods to investigate the size and shape of the sella turcica in children with unilateral cleft lip and palate (UCLP). Setting and sample population: Fifty-six healthy children with non-syndromic UCLP, from a major paediatric teaching hospital, with lateral cephalograms taken prior to alveolar bone grafting, were compared with an age-and sex-matched control group of healthy children without orofacial clefts, with lateral cephalograms taken prior to orthodontic treatment. Materials and methods: In this cross-sectional study, conventional measurements were performed on the sella turcica to measure width, height and area on lateral cephalograms. Sella shape was also analysed using 11 points defining the sella turcica contours, using geometric morphometrics. Procrustes superimposition was used to register all sella contour tracings to calculate average sella shape. Principal component analysis was applied to the residuals of the point coordinates, and principal components (PCs) of shape were extracted. Results: Statistically significant differences between the UCLP and control groups were found for sella posterior height, midpoint height, maximum height and area, where all of these were smaller in children with UCLP. Principal component analysis revealed that the first two PCs accounted for 84.7% of total shape variance. There was a statistically significant difference in sella shape between children with UCLP and control children. Conclusions: In children with UCLP, the sella turcica is shorter and with a smaller surface area when compared to matched non-cleft children. Moreover, sella turcica shape, when disregarding size, seems to differ to that of non-cleft children. K E Y W O R D S geometric morphometrics, sella turcica, unilateral cleft lip and palate 1 | INTRODUC TI ON The size and shape of the sella turcica has attracted some attention in the orthodontic literature, as it is readily visible on lateral cephalometric radiographs taken routinely for orthodontic diagnosis. Large variation has been seen both in the size and the shape of the sella turcica, 1-5 making the establishment of norms complicated.
