[Four cases of dysosmia with no vocal cords adduction during sniff (laryngeal dysosmia)].
The author first reported that the vocal cords adduct during sniff. This movement was observed both in normal and in anosmic subjects. In this paper four cases of dysosmia with no adduction of vocal cords during sniff was reported. The pattern of their olfactometry showed same tendencies, normal detective thresholds and inability of recognition and/or very low recognition threshold. With the observations and referenced articles, the author concluded that the vocal cord's adduction during sniff is a specific movement when the larynx concern with olfaction, and that the adductory movements is related to olfactory recognition. It was thought that the orbital cortex integrates the afferent stimulations from the larynx during sniff and olfaction from the nose. The author concluded also there exists these reported kind of dysosmia with no vocal cord adductory movement.
