開業医の立場からみためまい診療 : おっくうでない診察・検査システム作り Simplified Neuro-Otological Examination for Dysequilibrium in Out-Patient Clinics
The neurological and vestibular test for dysequilibrium is a time-consuming and troublesome task for most otolaryngologists in private out-patient clinics. Simplified neurological evaluation and vestibular tests were introduced for differential diagnosis of dysequilibrium.<BR>A stepping test involving ten steps with eyes open and closed, respectively, and evaluation of gaze nystagmus and positional nystagmus using an ultrared light camera are useful for the purpose. A simplified quantitative caloric test using 2 ml of ice water in necessary to detect the early stages of acoustic neurinome for unilateral cochlear symptoms or prolonged dysequilibrium.<BR>Using the merits of the patient's easy access to private out-patient clinics, a follow-up study revealed important findings in the central vestibular system, in which CT study had failed to find a lesion. Collaboration with neighboring hospitals and physicians with other specialities is essential for more accurate diagnosis and treatment of dysequilibrium.
