“…Vestibular function was studied by evaluation of the spontaneous, positional, and head-shaking nystagmus [19], and by the caloric stimulation test following the procedure of Fitzgerald and Hallpike [20]. The normal range for each test was obtained by performing the same tests on normal subjects at our Institute.…”

Many gadolinium-enhanced magnetic resonance imaging (MRI) studies focusing on the anatomy and pathology of the 7th cranial nerve have already been published. However, only scattered cases of herpes zoster oticus (HZO) have been described and only the MRI appearance of the soft temporal bone structures has been reported. Enhanced MRI was performed in 4 patients with HZO observed at the Department of Otorhinolaryngology of the University of Pisa. A good correlation was found between the clinical data and MRI findings in both the acute and chronic stages of the disease. The 2 cases with complete facial palsy presented prominent and diffuse enhancement of the 7th and 8th cranial nerves on postcontrast MRI, while the patient with grade III facial palsy showed more limited nerve enhancement. The patient with grade II facial palsy presented no MRI abnormalities. In our series, enhancement limited to the geniculate ganglion and to the labyrinthine segment of the facial nerve indicates a good prognosis while a widespread enhancement correlates with a poor prognosis. In conclusion, MRI with contrast may be useful during the acute stage of HZO because it can confirm the diagnosis and can provide prognostic information on the facial function.

“…The vestibular function was studied under electronystagmographic recording by evaluation of sponta neous, positional, cervical and head-shaking nystagmus [ 15], caloric stimulation using the Fitzgcrald-Hallpike method [ 16] and the visual suppression test [17]. The normal range for each test was obtained from audiological and vestibular laboratory results performed on normal subjects at the Institute of Otolaryngology of Pisa University.…”

Audiovestibular Involvement in Systemic Sclerosis

In order to evaluate the nature and association of audiovestibular disturbances and systemic sclerosis (SSC), 37 unselected SSC patients were studied with a detailed audiological and vestibular examination since November, 1987. Pure-tone audiometry, speech audiometry, impedance audiometry, brainstem response audiometry and vestibular function using electronystagmographic recording were performed. We found a rather frequent audiovestibular involvement (41 %). A hearing loss was found in 14 SSC patients; hearing loss was sensorineural in 10 cases and mixed in 4 cases. The latter revealed a finding similar to tympanosclerosis. Four patients showed altered vestibular test values and only one of these had normal hearing. Sensorineural deafness was the more frequent pathological finding and in all cases the site of lesion was cochlear. SSC appears to be directly responsible for audiovestibular damage, since in 12 out of 15 patients with such involvement, no other apparent cause could be revealed. SSC may be included among the autoimmune diseases which may cause audiovestibular disturbances.

“…As a result, the high prevalence of the target conditions in the included populations (6% for Ménière disease and 80% for vertigo) inflates the positive predictive values and decreases the negative predictive values. Furthermore, symptoms are probably Guidetti et al 32 Tseng et al 45 Harvey et al 34 Fujimoto et al 30 Goebel et al 31 Burgio et al 25 Jacobson et al 35 Vicini et al 46 Specificity ( Review more severe or pronounced in patients referred for secondary or tertiary care, which may inflate both the sensitivity and specificity. Although we used prevalence in a hypothetical primary care population to estimate likelihood ratios, we could not correct for this phenomenon.…”
