Previous studies exploring the effects of climate on the nasal region have largely focused on external craniofacial linear parameters, using dry crania of modern human populations. This investigation augments traditional craniofacial morphometrics with internal linear and volumetric measures of the anatomic units comprising the nasal complex (i.e., internal nasal cavity ...

BACKGROUND: Reference intervals are used to distinguish between healthy and diseased state. Ideally, they are defined using specimens only from 'healthy' individuals, but this is often difficult or impossible. In order to use routine clinical laboratory data, outliers must be removed before the underlying distribution and changes related to age ...

There has been little attention given to the relationship between variations in normal craniofacial morphology and swallowing physiology. This preliminary investigation evaluated the relationship between the Frankfort-mandibular plane angle (FMA) and hyoid displacement during swallowing. Hyoid movement was evaluated during 12-ml and 24-ml swallows of liquid barium in 12 healthy ...

We assessed the regulation of nasal patency supine in subjects with obstructive sleep apnoea syndrome (OSAS) compared to healthy controls. Healthy subjects increase nasal obstruction when changing body position from sitting to supine, possibly due to increased hydrostatic pressure in the head supine. Limited data indicate that this response is ...

Most studies on the effect of aging on esophageal motor function have shown that peristaltic function deteriorates with age. Esophageal motor function is traditionally studied by means of manometry and radiography. Distension of the esophagus with evaluation of active and passive mechanical parameters have become available during recent years. In ...
