Randomized Controlled Trial
Responses to trigeminal irritants at different locations of the human nasal mucosa.
Previous work suggests differences in the distribution of human intranasal trigeminal receptors. The aim of this study was to investigate these topographic differences for different concentrations of different trigeminal irritants using an electrophysiologic measure of trigeminal activation, the negative mucosa potential (NMP). ⋯ In agreement with previous work, the present data suggest that there are topographic differences in the responsiveness of the mucosa to chemical irritants.
