We devised a series of tasks as therapy for some types of vertigo. The task are as follows: 1) keeping the head in a position that elicits vertigo,2) head movements beginning in the sitting position,3) a short rest,4) body trunk movements,5) clockwise and counterclockwise body rotations while standing with eyes closed,7) walking forwards and backwards with eyes closed.
We obtained favo r able results with this therapy in one of ten patients with Meniere's disease, all seven patients with benign paroxysmal positional vertigo and six of ten patients with vertebro-basilar artery insufficiency. Our home therapy is recommended for all patients with benign paroxysmal positional vertigo and selected patients with vertebrobasilar artery insufficiency.

We investigated the effects of repeated stimulations for a few minutes on post-rotatory nystagmus. The subject sat on a rotatory chair that was suddenly decelerated following rotation at a constant angular velocity of 60 deg/s. The stimulation was given 3 times each in the leftward and rightward directions with a five minutes rest between trials. The subjects also recieved the stimulation following alcohol ingestion (0.5 ml/kg) and a 30-minutes rest. Post-rotatory nystagmus was recorded by electronystagmography and its duration and frequency were calculated.
The duration of post-rotatory nystagmus and its frequency were decreased slightly with repetition of the rotatory stimulation. However, following alcohol ingestion, repeated stimulation had no effect on the duration and frequency of the elicited nystagmus.

This study evaluated whether changes in ABR wave latencies can be predicted from the threshold audiogram in combination with age, sex and stimulation level by canonic correlation.
The canonic correlation for 536 subjects was 0.66 for the first canonic pair. With all six canonic variables, only 32% of the raw ABR varience could be explained by the hearing loss. The second variable accounted for 22%, showing the greatest effect of hearing loss on the ABR. Analysis of component loading received that: 1) wave I latency correlated with the slope of the hearing loss between 2000 and 8000 Hz, with the severity of the hearing loss at 4000 and 8000 Hz, and with sex; 2) age, sex and low-frequency hearing loss correlated with the I-V and III-V interwave latencies.

Body sway was analyzed in seven healthy subjects and three patients with central disorders. Power spectra were calculated by three different methods: 1) fast F ourier transform [FFT] with no smoothing procedures [degree of freedom 2],2) FFT with smoothing treatment [degree of freedom 26], and the maximum entropy method [MEM].
Although the spectra obtained from FFT with no smoothing procedures varied widely, those calculated with the second two methods were very stable and allowed detection of abnormal patterns.

We examined the influence of visual fields on upright standing by posturography in 19healthy adults. Each subject was placed on a stabilometer with the feet closed together under four conditions of visual fields: 1) eyes open,2) central area (30 degrees) of the visual fields open,3) central area (5 degrees) of the visual fields open,4) eyes closed.
The central area of the visual field had a greater influence on postural control of vision than the peripheral retina when gazing at a target. The central retina of 5 degrees accounted for nearly 50% of all visual contributions to postural stabilization, and that of 30degrees about 70% of all visual contributions. This is more prominent in anterior-posterior component. Power spectra ranging from 0.2 to 0.8 Hz were closely related to vision, especially in latral sway component. A peak at 0.3 Hz was noted with eyes closed and central area of 5 degrees open.

We analyzed the survival rates of 193 patients with maxillary cancers treated between 1955 and 1985. The majority of the cancer patients had stage III tumors, which accounted for about 66% of the total. The patients divided into three groups according to the period when treated: group A (1955 to 1961), group B (1962 to 1970) and group C (1971 to 1985). The survival rates were calculated according to therapeutic procedures.
Crude 5-year survival rates for stage III were 0% in group A,48% in group B and 39%in group C. The most effective therapy was the combination of preoperative radiotherapy, operation and postoperative radiotherapy. Despite remarkable adva n ces in diagnostic techniques, little progress has been made in detecting advanced cancer.

We reviewed 235 patients with laryngeal polyps treated by endolaryngeal microsurgery between January,1971 and December,1985. The patients were divided into 3 groups: those with vocal cord nodule, with vocal cord polyp (localized and diffuse) and with polypoid vocal cord.
Localized vocal cord polyp accounted for 49% the laryngeal polyps. Vocal cord nodule was more frequently observed in young adult females whose vocal cords were abused. This study suggested that mechanical stimulation, ageing and smoking were etiologic factors in polypoid vocal cord. However, smoking did not appear to be a factor in vocal cord nodule and localized vocal cord polyp. In addition,40.1% of the patients underwent surgery within one year from the onset of symptomes. The shortest duration of symptomes was observed in localized vocal cord polyp. The post-operative improvement rate was high in polypoid vocal cord.

We described our technique of rhinoplasty via an external approach through transcolumellar and marginal incision, and which allowed cartilage, septum and nasal bone to be visualized for greater surgical accuracy. Three patients with shifted nose,10 patients with posttraumatic septal deviation,3 patients with posttraumatic saddle nose,1 patient with Binder' s syndrome, and 15 patients with cleft lip nasal deformity were operated with this approach and satisfactory results were obtained. Compared with the conventional intranasal approach, our approach has allows better direct vision and easier surgical maneuver. The disadvantages are unsightly columellar scar and more radical surgical maneuver. However, a careful surgical maneuver overcomes these disadvantages.

Therapeutic results of 33 primary cases of maxillary sinus carcinoma treated with irradiation and intraarterial infusion of 5-FU between 1972 and 1984 were analyzed. The 5year crude survival rate for the group with stage T2 carcinoma (n =10) was 50.0%, and for those with T3 (n=15) and T4 (n=8) it was 46.7% and 25.0%, respectively. The overall 5year crude survival rate was 42.4%. Eight patients who did not undergo maxillectomy survived for 5 years after irradiation and intraarterial infusion. Recurrence of the tumor after the irradiation and intraarterial infusion occurred in 63.6%, and was frequently observed at the ethmoidal region and the orbita. In the areas in which the tumor extended to regions such as the ethmoid sinus and orbita, which are nourished by arteries other than the maxillary artery, conventional intraarterial infusion was ineffective for complete tumor eradication. Therefore, in most of the patients with advanced maxillary sinus carcinoma, partial or total maxillectomy following combined therapy of intraarterial infusion and irradiation is necessary to improve a prognosis.

A 44-year-old woman who complained of xerostomia and bilateral enlargement of the lacrimal and submandibular glands was referred to our clinic in January,1988. Physical examination, X-ray examination, computed tomography and scintigram revealed remarkable swelling of the lacrimal and submandibular glands and the decreased salivation. Serological examination suggested immunological abnormalities. Histological examination of the right submandibular gland showed marked fibrosis, lymphocytic infiltration and destruction of acini; these findings were compatible with chronic sclerosing sialoadenitis. In March,1989, bilateral swelling of the parotid glands appeared. However, the sialogram of the parotid gland showed normal appearance.
