The extratemporal course of the facial nerve must be completely understood if surgery is required for the removal of parotid and other tumors in the infratemporal space and skull base or if the nerve itself must be exposed when it has been severed. The key to mastering this surgery is to understand the anatomy of the parotid space and its relations to… (More)
The course of the facial nerve from its origin in the human brain-stem to the termination of its end fibers in the muscles of facial expression is reviewed in detail. The relation of the facial nerve to important adjacent structures is emphasized so that the aural surgeon is better prepared to explore in this intricate area.
Modern otologic surgery revolves around the use of the operating microscope. The surgeon must have a thorough knowledge of all structures in the temporal bone, particularly since surgery may now be directed to areas in its deeper portions. Of concern here is the whereabouts of the facial canal in its complex course through the temporal bone. A detailed… (More)
The junction of the petrosal and squamosal portions of the temporal lobe has important relationships that are of interest to the otologist. The resultant suture extends from the glaserian fissure across the top of the middle ear cleft and into the mastoid portion of the temporal bone. It may permit quick passage of infection from the middle ear to the… (More)

Sheppard A. The objectives of this randomized clinical trial (RCT) were to evaluate the local pharmacodynamic effects of triclosan dentifrice on GCF concentrations of inflammatory mediators in subjects with moderate plaque-induced gingivitis, and to measure systemic inflammatory mediators and document trends in levels. Gingivitis subjects were randomized… (More)
The vulnerability of the developing neostriatum to mild, but chronic hypoxia was evaluated in weanling rats exposed only in utero or from conception through postnatal day 10 to 0, 75, 150, and 300 ppm carbon monoxide (CO). The exposure conditions produced maternal carboxyhemoglobin (HbCO) levels of about 11, 19, and 27 percent. HbCO levels of 5 percent are… (More)
To investigate the perturbation of ubiquinone biosynthesis by a hypocholesterolemic drug, 3 beta-(2-diethylaminoethoxy)androst-5-en-17-one hydrochloride (U18666A), we measured the incorporation of radioactive mevalonate, methionine, tyrosine, and 4-hydroxybenzoic acid into ubiquinone in glioblastoma cells. These four precursors unanimously showed that… (More)
