Effect of anesthesia of the chorda tympani nerve on taste perception in humans

Gustatory function after microlaryngoscopy

“…Subjective complaints are thus unreliable to judge quantitative taste function. This is well known from experiences after middle ear surgery where even severing of the chorda tympani, and consequently ipsilateral hemiageusia of the tongue, frequently goes unrecognized by the patients [7,8].…”

“…Taste physiology has the particularity that selective loss of nerves supplying a distinct area of either the tongue or palatal surface are centrally compensated (for details see Lehman et al [7]). Therefore, measurable quantitative gustatory deficits (e.g.…”

“…Therefore, measurable quantitative gustatory deficits (e.g. hemiageusia) often remain unnoticed by the patients [7,14]. Quantitative and qualitative taste disorders can occur simultaneously or independently and they might be recognized or not by the patients.…”

One particularity of the complexity of gustatory physiology is that psychophysically measurable taste deficiencies frequently go unnoticed by the patients [7]. This observation is repeatedly made after middle ear surgery.…”

Effectiveness of Gabapentin for Treatment of Burning Mouth Syndrome

“…19 Chemosensory test results suggest a release of inhibition because the patient's rating of oral burning increased after anesthetization of the entire oral cavity. The pain increase after oral anesthesia is similar to the increase that occurred in a subset of patients in a previous report, 15 which had been taken to indicate a centrally mediated pain syndrome as a basis for some types of BMS.…”
