[HMPAO radionuclide of temporal cortex in the study of deafness].
A new method of dynamic exploration of central auditory pathway is presented, using measurement of cortical temporal perfusion variations, during auditory stimulation (tonal stimulation in normal hearing patients, electrical stimulation with promontory test in profoundly deaf patients). This study shows a perfusion increment in normal hearing and deaf patients with positive promontory test, which doesn't exist in a patient with negative promontory test. Further development of this study could help for optimization of post implantation auditory results.
