“…FMA, FNMA, and IFA increase with gestation from 16 weeks till around 28‐31 weeks and decrease minimally thereafter, through which we may infer the growth pattern of fetal profile. These findings provide valuable insights into the allometric growth relationship (change in shape and proportions in parts) between different parts of the fetal face . The mandible has a forward and downward growth before 28 weeks in reference to the maxilla.…”

Objective: To investigate the intraobserver and interobserver reproducibility of a novel sonographic parameter named facial maxillary angle (FMA) and to establish nomograms of FMA, inferior facial angle (IFA), frontal nasal-mental angle (FNMA), maxilla-nasion-mandible angle (MNMA), and fetal profile line (FPL) in Chinese fetuses. Methods: In this prospective cross-sectional study, FMA, IFA, FNMA, MNMA, and FPL were measured in 592 normal fetuses between 16 and 36 gestational weeks.FMA was measured twice by the same and another operator with a blinded method on the first 50 cases. The reference interval was defined as ±2SD. The efficacy of five sonographic markers was tested in 10 fetuses with micrognathia retrieved from the database of our unit. Results: The intraclass correlation coefficient (95% CI) of intraobserver and interobserver reproducibility of FMA was 0.937 (0.890-0.964) and 0.891 (0.809-0.938), respectively. FMA, FNMA, and IFA increased slightly from 16 weeks till 28-31 weeks and decreased minimally thereafter. FMA and FNMA made correct diagnosis in all affected fetuses; MNMA and IFA identified nine and eight cases respectively, and FPL only detected five cases.Conclusion: A fixed cutoff of 66°for FMA and 136°for FNMA may be adopted as simple screening criteria of micrognathia.

“… 4 This aspect of growth should be taken into account while making clinical decisions. According to Hagg et al, 5 the optimal age of maxillary expansion in girls is 12 to 13 years. However, in boys, maxillary inter-canine dimensions increase is seen until the age of 18.…”

OBJECTIVE: The aim of this cross sectional study was to assess serum insulin-like growth factor-1 (IGF-1) levels in female and male subjects at various cervical vertebral maturation (CVM) stages. MATERIAL AND METHODS: The study sample consisted of 60 subjects, 30 females and 30 males, in the age range of 8-23 years. For all subjects, serum IGF-1 level was estimated from blood samples by means of chemiluminescence immunoassay (CLIA). CVM was assessed on lateral cephalograms using the method described by Baccetti. Serum IGF-1 level and cervical staging data of 30 female subjects were included and taken from records of a previous study. Data were analyzed by Kruska-Wallis and Mann Whitney test. Bonferroni correction was carried out and alpha value was set at 0.003. RESULTS: Peak value of serum IGF-1 was observed in cervical stages CS3 in females and CS4 in males. Differences between males and females were observed in mean values of IGF-1 at stages CS3, 4 and 5. The highest mean IGF-1 levels in males was observed in CS4 followed by CS5 and third highest in CS3; whereas in females the highest mean IGF-1 levelswas observed in CS3 followed by CS4 and third highest in CS5. Trends of IGF-1 in relation to the cervical stages also differed between males and females. The greatest mean serum IGF-1 value for both sexes was comparable, for females (397 ng/ml) values were slightly higher than in males (394.8 ng/ml). CONCLUSIONS: Males and females showed differences in IGF-1 trends and levels at different cervical stages.

“…The linear face height measurements (N-Me, N-ANS, and ANS-Me) were also significantly larger in males (P = 0.000), P=0.000, P=0.001, and P=0.000, respectively). This was expected because males are generally larger than females [26].…”
