A patient with a submandibular gland carcinoma was found clinically to have a unilateral chorda tympani, lingual and hypoglossal nerve deficit. This unique neurological entity of loss of taste sensation of one-half of the tongue (hemiageusia), hemianaesthesia and hemiatrophy of the tongue, has not previously been reported.

OAKLEY, B. Reformation of taste buds by crossed sensory nervps in the rat’s tongue. Acta physiol. scand. 1970. 79. 88-94. Rat taste buds degenerate and disappear when their nerve supply is cut. Regeneration of the taste nerve fibres causes certain epithelial cells to differentiate into slender receptor cells comprising the taste bud. In this study by cross-union the glossopharyngeal (IXth) nerv...

Many of the chorda tympani fibers of crab-eating monkeys respond to more than one of the four basic stimuli (NaCl, sucrose, HCl, and quinine hydrochloride) as well as cooling or warming of the tongue. Fibers could be classified into four categories depending on their best sensitivity to any one of the four basic stimuli. Sucrose-best and quinine-best fibers are rather specifically sensitive to ...

Since lingual nerves may be transected during a variety of oral surgical procedures, including third molar removal, we have investigated two possible methods of repair. Quantitative morphological observations were made on feline chorda tympani and lingual nerves proximal and distal to transection injuries repaired either by epineurial suturing or by insertion of the cut ends into a perforated s...

Facial nerve neuromas occur throughout the course of the facial nerve and its branches, however lesions occurring on the chorda tympani branch are exceptionally rare. We present a case where the diagnosis was made intra-operatively; the patient was pre-operatively thought to have had a cholesteatoma. Total resection is the treatment of choice for these cases. Early diagnosis, aided by high reso...

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...

Regulatory Integrative Comp. Physiol. 278: R720–R731, 2000.—We tested whether the recovered ability of rats to discriminate NaCl from KCl after chorda tympani nerve transection (CTX) is causally linked to nerve regenerat...
