We report a 51-year-old man with mild left central facial palsy and left Avellis' syndrome due to a small medullary infarction. On admission, neurological examination revealed hoarseness, dysphasia, absent left gag reflex, palsies of the left vocal cord and left soft palate, and hypalgesia and thermohypesthesia on the right side of the trunk and extremities. In addition, he had a mild left central facial palsy. He had no nausea, vomiting, vertigo, hiccups, nystagmus, Horner's sign, facial numbness, or paresis or ataxia of the limbs. A T2 weighted MRI showed a small, high signal intensity area in the left dorsal region of the medulla and this lesion was presumed to involve the nucleus ambiguus and a part of the spinothalamic tract. These findings suggest that an aberrant supranuclear pathway, looping around the nucleus ambiguus to the facial nucleus exists in our patient.

A brief history of the vestibular neurectomy is given. This treatment modality was introduced in Denmark by us, using the experiences obtained by the use of translabyrinthine treatment modality for vestibular schwannoma surgery. This paper presents our experiences with this type of surgery (translabyrinthine, retrolabyrinthine and retrosigmoid vestibular nerve section) from 1980 to 1996, including 43 operations in 42 patients. The patients had all been treated with conventional methods without success and were all severely handicapped by their attacks of vertigo. The mean age was 51 years, postoperative observation time between 2 and 15 years, with a mean of 6.4 years. The vertigo was controlled in 88% of the patients, while postoperative imbalance occurred in 14 patients, mainly due to the ablation of the vestibular labyrinth and not by episodic vertigo. A total of 39 patients indicated that they were satisfied with the operation. Six patients were deaf before surgery and 92% of the remaining patients retained their preoperative hearing. Postoperative complications were few, including two re-operations for CSF leaks, one patient with a slight transient facial nerve paresis and one transient VI nerve paresis. The results compare favorably with results from other authors. Retrosigmoid vestibular nerve section is an effective treatment modality to be offered to patients in whom other modalities have failed. Information about the efficacy and leniency of the treatment should be given to the patient's organization in order to diminish the fear of an intracranial intervention. Surgical experience is necessary in order obtain good results, the number of patients needing the operation is small and centralization of the treatment is mandatory.

The aim of this paper was evaluation of vertigo frequency in otosclerotic patients (group I N = 64) in comparison with control group (group II N = 20) and in people after stapedectomy (group III N = 64). Furthermore electronystagmographic recording spontaneous nystagmus, positional nystagmus were made. Computer analyses of ENG-recording and automatic calculation of directional preponderance and canal paresis were used. Vertigo was in 12% otosclerotic patients while in equal of age control group only in 5% subjects. Spontaneous nystagmus in 20% and positional nystagmus in 27% were recorded in otosclerotic patients while that took place in 10% and 15% control group respectively. Asymmetric reaction in-group I was in 21% cases and in 10% subject's in-group II. Real directional preponderance was in 18.8% otosclerotic patient's in-group I and it was absent in-group II. Obtained results revealed existence vestibule disturbances in otosclerotic patients. More frequent labyrinth objective symptoms were registered post stapedectomy. Vertigo in 21%, spontaneous nystagmus in 58%, positional nystagmus in 61%, asymmetric reaction in 48% was noted. Marks of vestibule and organ injury in otosclerosis and post stapedectomy were met. Vestibule disturbances were irritate and inconstant character. It is appears to be needed examination of balance system before stapedectomy in the planning of stapes operation and after operation on stapes. Presence of vestibular symptoms after stapes surgery is not cause less post stapedectomy improvement of hearing but sometimes postoperative improvement of hearing is better for lower frequencies in patients group with vestibular disturbances than in-patients without these symptoms.

The authors present a patient with benign paroxysmal positional vertigo of the right horizontal semicircular canal who developed persistent vertigo with spontaneous horizontal nystagmus to the left and caloric hypoexcitability on the right after a head shaking maneuver. Both spontaneous nystagmus and canal paresis resolved after repeated shaking of the head. The most probable mechanism of this type of vertigo is plugging of the horizontal canal by otoconial particles with a negative endolymph pressure between plug and cupula.

The objective was to assess the cochleovestibular symptoms in migraine. Therefore, a questionnaire form was prepared to record the data obtained from 20 migraineurs. All patients were assessed with audiometry, bithermal caloric testing and auditory brainstem response testing (ABR) between the migraine attacks, and 8 of them were also assessed during the attacks. Dizziness (30%) was the most common symptom that was followed by vertigo (25%) and tinnitus (20%). All patients had hearing within normal limits. Positional test (Hallpike maneuver) was positive in 2 (10%). Bithermal caloric testing revealed canal paresis in 3 (15%) patients. ABR results were normal in 13 patients. Seven patients (35%) had abnormal ABR results. Four of them (20%) had elongation in the absolute wave latencies (wave I, III and V) and normal IPLs of wave I-III, III-V and I-V. Three (15%) patients had elongation in the absolute wave latencies as well as in the IPLs of wave I-III, III-V and I-V. In conclusion, cochleovestibular symptoms can be seen in migraineurs. The test results between and during attacks are similar. The subjective cochleovestibular symptoms did not correlate with the objective tests performed (audiometry, ABR and caloric testing).

We clinically analyzed 15 cases of perilymphatic fistulas--11 caused by barotraumas and 4 idiopathic--identified by surgery between March 1995 and March 1999 at the Hyogo College of Medicine and affiliated hospitals. Subjects were 11 men and 4 women (aged 14 to 79 years (mean: 46.7 years)). All showed hearing loss in audiography and 12 cases reported tinnitus--stream-like in 5 and poping in 4. Dysequilibrium was seen in 9 cases. Perilymph leakage was detected intraoperatively from the oval window in 9, from the round window in 4, and from both windows in 1, while another had leakage from the fissura ante fenestram. After surgery, hearing level improved by over 10 dB in 9 of the 11 cases operated on within 14 days after onset. Hearing did not improve in 3 of 4 operated on later. Vertigo disappeared after surgery. Dizziness tended to persist in those having canal paresis or paralytic nystagmus before surgery. We suggest that patients with progressive hearing loss should be operated on as soon as possible and that patients with dysequilibrium or without response to conservative treatment undergo surgery within 14 days of onset.

We compared the results of analysis of vestibulo-ocular reflex (VOR) obtained by manual rotation in routine vestibular clinical practice with that of caloric testing, and examined the validity and limitations of VOR analysis as a test for the estimation of peripheral vestibular function and imbalance. VOR response was recorded in daily vestibular clinical examinations by manually rotating the standard clinical chair for approximately 30 s. VOR gain was slightly, but significantly, correlated with the peak slow phase velocity of caloric response (r = 0.50, p < 0.001). However, 8 out of 12 patients with no caloric response failed to exceed the range of two standard deviations of the mean value of age-matched normal subjects, indicating that it is clinically difficult to use VOR gain alone as a estimate of unilateral vestibular function. VOR directional preponderance (VOR DP%) correlated well with caloric canal paresis (CP) (CP%; r = 0.89, p < 0.001). VOR DP% was within the normal range in patients with caloric CP% < 40 and exceeded the normal range in most cases with caloric CP% > 80. VOR DP% varied widely when caloric CP% ranged between 40 and 80. The effect of vestibular compensation on VOR DP% was examined by plotting VOR DP% divided by caloric CP% (DP/CP) against the number of days since the onset of vertigo in patients with vestibular neuritis or sudden deafness with vertigo. DP/CP was large within 50 days of the onset of vestibular damage, especially when caloric CP% was < 80, and gradually decreased with time. These results indicate that determination of VOR DP% should contribute to the early diagnosis of fresh vestibular imbalance, especially in daily clinical practice, because this type of VOR recording can be performed in < 1 min in routine vestibular clinics. The decay time constant of DP/CP was larger when caloric CP% exceeded 80, indicating that vestibular compensation proceeds more slowly when the vestibular damage is severe.

A 66-year-old woman was admitted to our hospital because of vomiting, dizziness and vertigo. Neurological examination on admission revealed only upbeat nystagmus without cranial nerve symptoms, paresis, cerebellar signs or sensory disturbances. Magnetic resonance(MR) images demonstrated a new T 2 high intensity and T 1 iso-intensity signal lesion in the right upper medial medulla. This medial medullary infarction caused central vestibular dysfunction. MR angiography and digital subtraction angiography demonstrated a persistent primitive hypoglossal artery (PPHA) originating from the right internal carotid artery to the vertebrobasilar artery associated with the stenosis of the right internal carotid artery at the level of the cervical bifurcation. This is the first report of medullary infarction with persistent carotid-basilar anastomosis. We suspected this medullary infarction was caused by artery to artery embolism in the branch of the right vertebral artery through the PPHA distal originated from the stenosis of the right internal carotid artery.

A 25-year-old female developed permanent, fluctuating sensorineural hearing loss (SNHL), disabling vertigo, and tinnitus following an uneventful spinal anesthesia for cesarean section. At her first visit to the ear-nose-throat (ENT) department approximately 2 months postoperatively, pure-tone thresholds revealed profound SNHL on the right side whereas thresholds were within normal limits on the left side. The recruitment score (SISI) was 95% at 2000 Hz on the right side. Directional preponderance towards the right and the right canal paresis were evidenced by bithermal caloric testing. At follow ups the pure tone thresholds have shown some improvement, but fluctuating SNHL, disabling vertigo attacks, and tinnitus have remained. These findings imply a cochlear pathology causing endolymphatic hydrops possibly induced by lumbar puncture for spinal anesthesia.

We report the recovery of the inferior vestibular neural system disorder by monitoring the vestibular-evoked myogenic potential (VEMP) in two patients suffering from acute sensorineural hearing loss with vertigo. Patients presented absent VEMP, canal paresis, and severe hearing disorder. After 10 months, the function of the inferior vestibular neural system was recovered in both cases while that of the superior vestibular neural system was recovered in one case and partially recovered in the other. In addition, the hearing sensitivity was only partially recovered in both cases. The recovery of the inferior vestibular neural system was confirmed by our current results. These results suggested that time course of recoveries of the superior and inferior vestibular neural systems, and of the cochlear neural system, were somewhat different in the two cases.
