Date: June 2011. Source: American Journal of Physical Anthropology, 146(4): 560–568. Abstract: Down syndrome (DS), resulting from trisomy of chromosome 21, is the most common live-born human aneuploidy. The phenotypic expression of trisomy 21 produces variable, though characteristic, facial morphology. Although certain facial features have been documented quantitatively and qualitatively as characteristic of DS (e.g.,…

Date: March 2011 Source: Journal of Oral Maxillofacial Surgery, 69(3): 663-76. Abstract: Surgical correction of obstructive sleep apnea (OSA) syndrome involves understanding a number of parameters, of which the 3-dimensional airway anatomy is important. Visualization of the upper airway based on cone beam computed tomography scans and automated computer analysis is an aid in understanding…
