During the past 14 years from 1975 to 1989, two-nation-wide surveys of Meniere's disease have been carried out by the Vestibular Disorders Research Comittee of Japan, supported by the Ministry of Health and Welfare of Japan. However, an epidemiological case-control-study including normal subjects has not yet been performed by this committee.<BR>In this third survey, therefore, 148 patients with definite Meniere's disease, 138 with non-Meniere vertigo, 113 with rhinolaryngological disorders, and 165 normal control subjects were collected by the 16 mem-bers of the Research Committee from June 1990 to November 1990. The controls were selected to match as closely as possible the sex, age and location of the Meniere's disease patients.<BR>The characteristic epidemiological features of Meniere's disease in Japan were :<BR>1) Sex-ratio : 63 males to 85 female.<BR>2) Age-distribution : Peak at 40-49 years for males and 30-39 years for females.<BR>3) Season and Time of Onset : Often initial vertigo attacks occurred in the afternoon or in the morning.<BR>4) Occupational Distribution : There was a higher incidence of Meniere's disease among technicians or white-collar workers than among farmers, laborers engaged in blue-collar work, as in the 1st and 2nd surveys. However, the number of house-wives was lower in this 3rd survey.<BR>5) Personal characteristics : In patients with Meniere's disease, precisionism and neurosis were more frequently observed than in non-Meniere's vertigo.<BR>6) Preceding Events : Mental and physical fatigue before vertigo attacks was frequent in Meniere's disease patients.<BR>These epidemiological features reconfirm that the occurrence of vertigo attacks in Meniere's disease is influenced much more by individual factors than by environmental factors, as was found in the 1st and 2nd Nation-wide surveys. However, a marked difference in sex ratio with female preponderance was found in the 3rd survey.<BR>The incidence of bilateral Meniere's disease was 16.2% (24/148), higher than in the 1st and 2nd surveys.

We treated a 20-year-old man with a blind bullet wound of the left temporal bone and perforating bullet wounds of the right temporal legion, the right upper arm and right femur.<br>Following physical examination, X-P, and CT, a bullet was detected in the left temporal bone. However, other wounds did not contain bullets. Emergency surgery was performed. The bullet was suspected to have entered through the posterior part of the mastoid tip, pass through the mastoid cavity and stopped at the tympanum. The facial canal was partially broken at the vertical portion, however the facial nerve was not damaged. The bullet was removed after resecting the posterior external auditory canal. Tympanoplasty type i combined with external canal wall drilling-down technique was performed.<br>The patient showed left facial palsy after surgery. However, this gradually improved. The postoperative course in his left ear was good without infection, although the patient was deaf in that ear.

Two cases of horizontal eye movements disorders due to pontine lesions are reported and their clinical symptoms described. Case 1, a 52-year-old female, showed right lateral gaze paralysis together with right facial paralysis, vestibular dysfunction and scanning speech after surgery on an epidermoid cyst in the 4th ventricle. Case 2, a 56-year-old female, displayed right lateral gaze paralysis combined with right facial paralysis, vestibular dysfunction, right deafness and left hemiplegia following pontine hemorrhage. The right lateral gaze paralysis of both cases were analyzed and speculated to have resulted from combined disorders of the right abducens nucleus, the right PPRF (paramedian pontine reticular formation) and the right MLF (medial longitudinal fasciculus) in the pontine tegmentum.

Meniere's disease is represented by episodic vertigo (vestibular symptom), tinnitis and hearing loss (cochlear symptom). It is possible to devide patients with Meniere's disease into three groups; those with cochlear and vestibular symptoms starting at the same time, and those with the vestibular symptoms starting before or after cochlear symptoms: In this presentation, we studied the clinical differences of these three groups. The following results were obtained.1. In the case of cochlear Meniere's disease, the cochlear symptom is slight and it is easy to acquire the vestibular symptom. The cause of cochlear Meniere's disease was considered to be the existence of endolymphatic hydrops. Compared with frequency of bilateral Meniere's disease, bilateral cochlear Meniere's disease was more found.2. In the case of vestibular Meniere's disease, the vestibular symptom is slight and it is difficult to acquire the cochlear symptom. The cause of vestibular Meniere's disease, in all cases was not considered to be the existence of endolymphatic hydrops.3. In the case of Meniere's disease with vestibular symptoms starting after the cochlear symptoms, both the vestibular symptoms and cochlear symptoms are heavy. In the case of Meniere's disease with vestibular symptoms starting before the cochlear symptoms, both symptoms are slight.
