STUDY OBJECTIVES To define differences in the skeletal components of facial structure predisposing to the obstructive sleep apnea/hypopnea syndrome (OSAHS) by a comparison of the craniofacial complex between people with OSAHS and their siblings without OSAHS. DESIGN Case-control study using sibling pairs. SETTING Scottish Sleep Centre. PARTICIPANTS 104 patients with OSAHS living in Scotla...

Volume images of tongue were acquired by MRI from one subject uttering a corpus representative of French allophone articulations. Supplementary images of hard palate, jaw, and hyoid bone were acquired by CT. The three-dimensional tongue surface outline was represented, for each of the 46 articulations of the corpus, by a mesh obtained by fitting a generic mesh to the set of tongue contours trac...

The geniohyoid muscle (GH) is a critical suprahyoid muscle in most mammalian oropharyngeal motor activities. We used sonomicrometry to evaluate regional strain (i.e., changes in length) in the muscle origin, belly, and insertion during suckling in infant pigs, and compared the results to existing information on strain heterogeneity in the hyoid musculature. We tested the hypothesis that during ...

OBJECTIVE To characterize the changes in the anteroposterior dimensions of both the retropalatal and retrolingual airway spaces of the pharynx and hyoid bone position during hypoglossal nerve stimulation under general anesthesia in subjects with obstructive sleep apnea. STUDY DESIGN Cross-sectional. SETTING Academic center. SUBJECTS AND METHODS Cross-table fluoroscopic images obtained dur...

To the Editor: We appreciate the comment provided by Gun et al regarding our recently published manuscript. We agree that the digastric and stylohyoid muscles are found lateral to the lingual artery as based on embryologic origins as well as previously described anatomic dissections. We contend, however, that the dissections presented do indeed show the posterior belly of the digastric. The ima...

The phenotypic appearance of the head of animal species depends strongly on the shape of the skull. The present study has been carried out on morphological and radiographic characteristics of skull of the Indian Blackbuck. The skull comprised of cranial and facial bones. The cranial bones included occipital, sphenoid, ethmoid, interparietal, parietal, frontal and temporal. The occipital was a s...
