Assessment of the facial features and chin development of fetuses with use of serial three-dimensional sonography and the mandibular size monogram in a Chinese population.
American journal of obstetrics and gynecology, 2004Co-Authors: Meng-yin Tsai, Kuo-chung Lan, Jen-huang Chen, Shiuh-young Chang, Te-yao HsuAbstract:Abstract Objective Our purpose was to evaluate whether the application of serial three-dimensional (3D) sonography and the mandibular size monogram can allow observation of dynamic changes in facial features, as well as chin development in utero. Study design The mandibular size monogram has been established through a cross-sectional study involving 183 fetal images. The serial changes of facial features and chin development are assessed in a cohort study involving 40 patients. Results The monogram reveals that the Biparietal Distance (BPD)/Mandibular body length (MBL) ratio is gradually decreased with the advance of gestational age. The cohort study conducted with serial 3D sonography shows the same tendency. Both the images and the results of paired-samples t test ( P Conclusions The serial 3D sonography and mandibular size monogram display disproportionate growth of the fetal head and chin that leads to changes in facial features in late gestation. This fact must be considered when we evaluate fetuses at risk for development of micrognathia.

Case-Control Study of Cephalometrics in Patients with Moyamoya.
World neurosurgery, 2019Co-Authors: Nida Faheem, Domenico A. Gattozzi, Ernest J. Madarang, Paul J. Camarata, Gary S. GronsethAbstract:Objective To determine whether cranial metrics consistently differed between patients with moyamoya and age-, sex-, and race-matched controls. Methods Patients diagnosed with moyamoya disease by cerebral angiogram were obtained from a prospectively collected database through the Department of Neurosurgery at the University of Kansas Medical Center. Control patients matched by decade of age, sex, and race were collected through a deidentified hospital database by International Classification of Diseases-9 and 10 codes for ischemic stroke to identify patients with computed tomography angiograms. Imaging studies for both groups were analyzed to obtain 6 skull metrics: maximum anterior to posterior Distance, maximum Biparietal Distance, bregma to occiput Distance, right carotid canal diameter (CCD), left CCD, and cephalic index. Results Forty-five patients were identified in each cohort. Measurements of mean anterior to posterior skull diameter, mean Biparietal skull diameter, bregma to occiput Distances, and calculated cephalic index did not demonstrate a statistically significant difference between patients with moyamoya and control patients. Right carotid canal mean diameter was 4.8 mm for the moyamoya group and 5.4 mm for the control group, with a significant raw mean difference of −0.61 mm (95% confidence interval, −0.95 to −0.27). Left CCD was 4.7 mm for the moyamoya group and 5.5 mm for the control group, resulting in a significant raw mean difference of −0.76 mm (95% confidence interval, −1.09 to −0.43). Conclusions This study identified 2 skull parameters as statistically different in patients with moyamoya compared with a matched control group of patients with ischemic stroke: right CCD and left CCD.

A case of de novo interstitial deletion of chromosome 5(q33q34)
Clinical Genetics, 2008Co-Authors: Jacques C. Giltay, Klasien B. J. Gerssen-schoorl, Gert H. J. Luitse, Hans G DauwerseAbstract:The present paper describes a girl with a small de novo deletion of chromosome 5(q33q34). Fluorescence in situ hybridisation with locus specific probes was used to define the extent of this deletion. Clinical features in this patient are microcephaly, dysmorphic facial features such as epicanthus, small Biparietal Distance and retrognathia, four-finger lines on both hands and mild mental retardation.
