[Transtympanic neurectomy of the vestibular and cochlear nerves (author's transl)].

Tympanotomy and a transvestibular approach to the fundus of the internal auditory meatus is described. The surgical technique is modified from that proposed by Alvarez de Cozar and Antoli-Candela in 1970. The surgical anatomy of the operative sites is detailed. The surgical procedure is found indicated in patients in whom preservation of hearing is not considered and vestibular neurectomy required. The described technique provides a simple but efficient and safe alternative to the translabyrinthine approach to the internal auditory meatus for division of the vestibular and cochlear nerves.

Glutamate concentration in whole saliva and taste responses to monosodium glutamate in humans.

It is universally accepted that saliva plays an important role in taste sensations. However, interactions between constituents of whole saliva and the five basic taste modalities are still poorly understood. The aim of the present study was to evaluate possible relationship between endogenous glutamate (Glu) levels in whole saliva and taste responses to a prototypic umami substance, monosodium glutamate (MSG; 0.03-10.0%). Rated intensity and pleasantness of MSG taste was studied in healthy volunteers divided into a high glutamate (HG) in saliva (HG; n = 19) and low glutamate in saliva (LG; n = 18) group based on the median split level of salivary Glu. The HG and LG group did not differ in terms of electrogustometric thresholds, rated intensity of the MSG samples and pleasantness of distilled water and the lower MSG concentrations (0.03-1.0%). Perceived intensity of water taste was significantly (P < 0.05) higher in the LG subjects. The LG group rated the higher MSG concentrations (3.0-10.0%) as more unpleasant (P < 0.01). The difference remained significant after controlling for a between-group difference in age. The present results suggest that individual differences in salivary Glu levels may alter hedonic responses to suprathreshold MSG concentrations.

Taste responses in sons of male alcoholics.

The aim of the present study was to compare taste responses (intensity and pleasantness/unpleasantness) to sweet, bitter, sour, and salty solutions in sons of male alcoholics (SOMAs) and control subjects with no family history of alcoholism. In addition, responses to Coca-Cola flavour were evaluated in both groups. Unpleasantness of salty solutions was significantly enhanced and intensity of sour solutions tended to be higher in the SOMAs. There were no other differences between the groups. Thus, contrary to previous suggestions, genetically determined vulnerability to alcohol dependence may not be associated with altered responses to sweet substances. The present findings would rather suggest that increased aversive responses to salt taste may predict future development of alcohol dependence.
