CONCLUSIONS: The underlying pathophysiological mechanisms of the posterior nasal nerve (PNN) resection involved the suppression of the secretogogue motor and the inhibition of neurogenic inflammation induced by parasympathetic and sensory denervation.
OBJECTIVE: The study was designed to clarify the underlying mechanisms of the resection of the PNN.
PATIENTS AND METHODS: Ten patients with allergic rhinitis and non-allergic chronic rhinitis were enrolled in the study. Clinical symptoms were evaluated before and after administration of oxitropium bromide aerosol, and after the PNN resection. Biopsy specimens from the inferior turbinate mucosa obtained from five patients before and after resection of the PNN were examined.
RESULTS: The application of oxitropium bromide resulted in a significant reduction of both watery rhinorrhea and nasal obstruction, but not sneezing or postnasal drip. Resection of the PNN also significantly improved both rhinorrhea and nasal obstruction. Morphometric analysis of the density of the nasal gland showed a significant reduction, whereas no significant change was recognized in the density of the vessels. A significant reduction in the number of infiltrating neutrophils, eosinophils, and lymphocytes was recognized.
