In order to study the sympathetic innervation of nasal polyps and polypoid mucosae, the glyoxylic catecholaminergic histofluorescence method was employed in the examination of specimens taken from patients who had nasal disorders with polyps or polypoid mucosae. One percent neutral red was used as a counterstain. Abundant sympathetic fibers were present around the vessels of the pedicle of nasal polyps. However, no sympathetic innervation was found in the body and apex of the polyps. In the microscopical views of polypoid formations, there were no obvious differences between non-diseased nasal mucosa and polypoid mucosa in the distribution of sympathetic innervation. Based on these results, the following conclusions were drawn: (1) The loss of the sympathetic innervation was suggested to an important role in the pathogenesis of nasal polyps. (2) During polypectomy, the polyp had better be removed along with the pedicle for there is abundant sympathetic innervation and it will result in reduced bleeding.
