“…However, they also found that subjects whose nasal patency was slightly less on one side had lower thresholds on that side, but it was not clear if this accounted for their reported interaction with handedness. Nasal patency would also be affected by cyclical changes in nasal airflow (Principato & Ozenberger, 1970), but recent evidence indicates that such changes are not very regular and do not favor one nostril over the other in any systematic fashion (Gilbert & Rosenwasser, 1987). Whether the results ofYoungentob et al bear any relation to the phenomenon uncovered in the present study remains a question for future research.…”

Olfactory discrimination was tested with eight pairs of odors presented to each nostril of each subject. Ninety-nine subjects were tested; there were equal numbers of left-and right-handers, as well as both sexes. Detection thresholds for phenylethyl alcohol were measured separately in each nostril using a forced-choice staircase procedure. In addition, a verbal dichotic listening test known to be sensitive to language lateralization was administered. Results indicated that discrimination performance was significantly better when the stimuli were presented to the right nostril than when they were presented to the left, but no differences between the nostrils in detection thresholds were found. The right-nostril advantage did not vary as a function of sex or handedness, and did not bear any relation to language lateralization as measured via dichotic listening. The asymmetry for olfactory discrimination replicates an earlier study and is interpreted in terms of a possible specialization of function within the right cerebral hemisphere.

“…Routine clinical examination substantiates this, as do nasal airway resistance studies in which unilateral resistance can be decreased by two thirds with selective decongestion of the inferior turbinate mucosa [1], A congested middle turbinate, however, rarely contributes signif icantly to nasal obstruction.…”

The results of turbinate reduction surgery carried out on 307 patients are reviewed. This is a retrospective study over 16 years. The results of submucosal diathermy with and without outfracture, partial inferior turbinectomy and linear cautery were all equally disappointing in the long term. At 1 month postoperatively the overall success rate, as defined by patient satisfaction, was 82%, but this declined steadily with time to 60% at 3 months, 54% at 1 year and 41 % at 1–16 years. There was no significant difference found in the success rates between methods of turbinate reduction used. These findings are compared with more optimistic reports in the literature and their relevance to current surgical practice is discussed.

“…Stoksted [1952] and Principato and Ozenberger [1970] investigated the cyclic respiratory changes in the nasal mucosa and its vasculature in man. Moller and Fahren-additional surface area available, when these gutters open, may enhance the heat transfer capacity of the nasal mucous mem brane or act as a reserve of ciliated surface area which could be brought into play in case of inflammatory conditions of the nasal mucosa.…”

Histomorphologic Studies of the Nasal Cavity of Sheep (<i>Ovis aries</i>) and Its Significance in Temperature Regulation of the Brain

10 sheep were used for light microscopic studies to describe the distributions of the blood vessels, epithelium, and glands of the nasal cavity. The animals were killed following intramuscular injection of Rompun solution (xylazine hydrochloride). The heads were sawed and tissues were taken from the alar fold, respiratory, and olfactory regions. More vascularity was noticed in areas of the nasal cavity that were in direct contact with the airstream. Moreover, in the submucosa, the presence of arteriovenous anastomoses, collagen fibers, elastic fibers, thick-walled or cushion veins, and free smooth muscle cells was observed, gradually decreasing from the rostral to caudal regions. The tunica media of the arteries was very thin in the vestibular region and relatively thicker in the respiratory region. On the other hand, luminal diameters of the arteries were very small in the respiratory region and relatively larger in the vestibular region. In addition, a large number of intra-arterial bolsters was present in the respiratory region, but there were fewer in the olfactory region, and they occurred with still less frequency in the vestibular region.
