Chorda tympani nerve function after myringoplasty.
This is a cross-sectional study design aimed to determine the prevalence of Chorda Tympani Nerve (CTN) injury and related symptoms following myringoplasty. Thirty patients were included in this study. The methods used were measuring taste thresholds using electrogustometer to map taste threshold on the anterior two-third of the tongue on the operated side with the non operated side as the contr...
متن کاملANATOMICAL VARIATIONS OF THE CHORDA TYMPANI NERVE
The author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. The studies were performed on 200 specimens of human temporal bone. It was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), an...
متن کاملMaintenance of chorda tympani salt taste responses after nerve transection in rats.
To determine whether neurophysiological responses to salts change differentially or in parallel during long recording sessions after nerve transection, we recorded from the cut chorda tympani nerve in rats while stimulating the anterior tongue with NaCl, LiCl, NH4Cl and KCl. In nerve preparations that were not disturbed once recording began, responses were maintained at or above initial magnitu...
متن کاملNeuropeptides modulate rat chorda tympani responses.
The neuropeptide leptin has been shown to selectively modulate rat chorda tympani (CT) responses to sweet tastants. To explore whether other neuropeptides can modulate such responses, rat whole nerve CT responses to NaCl, HCl, quinine HCl, and sucrose were measured while administering cholecystokinin-8 (CCK-8), substance P(4-11) (SP(4-11)), or calcitonin gene-related peptide (CGRP). To avoid po...
متن کاملDevelopmental changes in taste responses from glossopharyngeal nerve in sheep and comparisons with chorda tympani responses.
To learn whether there are developmental changes in salt and acid taste responses from the posterior tongue, we recorded from the glossopharyngeal nerve, which innervates taste buds in circumvallate papillae, in sheep fetuses, lambs and adults. Multifiber responses to NH4Cl, KCl, NaCl, LiCl, citric and hydrochloric acids were expressed as ratios, relative to responses for two standard chemicals...
