Thirty cases of cholesterin granuloma and 17 cases of simple inflammatory granuloma in the middle ear were studied.
They were selected from the cases of chronic middle ear inflammation operated in our department.
None of the cases of cholesterin granuloma were complicated by cholesteatoma, adhesion of the tympanic membrane or tympanosclerosis.
There was no significant difference between the two groups in preoperative hearing, the site of the lesion, the pathological change in the auditory ossicles or the method of surgery.
However, the postoperative hearing was significantly worse in those with cholesterin granuloma than those with simple granulation tissue. In addition, some patiants in the former group exhibited middle ear effusion, worsened bone-conduction hearing, or recurrence of cholesterin granuloma after surgery.
Therefore, it is necessary to establish appropriate therapy for this disease.

One hundred and fifteen ears in 104 patients with congenital ossicular anomalies had been surgically treated in our department between 1971 and 1988. Among them 62 ears in 55 cases, which had normal external ear canals and normal tympanic membranes, were investigated. We studied the correlation between the hearing level after surgery and the characteristics of the ossicular anomaly detected during operation. The ossicular anomalies were classified according to embryologic criteria, such as monofocal type and multifocal type, and by according to whether the ossicular chain had been fixed or not, and disconnected or not. The postoperative hearing level was better in the monofocal type group than in the multifocal type group, and it was better in the group with ossicular disconnection than in the group with ossicular fixation in most cases.

Hematological examinations were performed in 53 patients with sudden deafness.
More than 50% of the patients had abnormal (high or low) erythrocyte sedimentation rates an increased adhesiveness of platelets, and more than 25% of them showed abnormal (increased or decreased) white blood cell counts and abnormal (increased or decreased)viscosity of whole blood.
These hematological tests were usuful in assessing the pathogenesis of the disease, i.e., abnormality in hemodynamics, thrombosis in the inner ear artery or auto-immune deafness. These findings may be useful in the application of radical treatment for the patient suffering from sudden deafness.

A new computer-aided speech audiometer (CASA) was developed. The system which employs a 5-choice speech discrimination that method, operates on a personal computer (NEC-9801) with auxiliary hardware which included D/A converter for speech signal replay, touch screen for input of patient's choice among the alternative syllables on the CRT, and an electronic attenuator and amplifier. Advantages of this system: 1) touch screen simplifies patients' response for both slow and quick patients; 2) testers' scoring time and error in scoring task are reduced; 3) a data bank were automatically built for future reference.

We investigated intragastric pressure and respiration induced by electric stimulation of the semicircular canal nerve in 20 white domestic rabbits. A stainless steel bipolar electrode with a diameter of 20 μm was implanted chronically in the horizontal or anterior canal nerve at each animal. The intragastric pressure was recorded by using a balloontransducer system during electric stimulation of the canal nerve through the electrode without general anesthesia or under slight Nembutal anesthesia. Both the initial depression with a latency of 40 msec and the following second depression with a longer duration in the intragastric pressure induced by each electric pulse train were observed. Prolonged depression of the pressure, suppression of spontaneous peristalsis in the stomach and forced respiration occurred following strong stimulation for a relatively long time. Those responses were suggested to be induced by canal stimulation via the sympathetic nervous system. Thus, the forced respiration may be involved in vestibular vomiting.

In 2 patients with delayed endolymphatic hydrops, labyrinthectomy was carried out because they had severe vertiginous attacks in spite of continuous conservartive drug therapy.
The process of central compensation in vestibular asymmetry after surgery was evaluated by observation of nystagmus and movements of the center of gravity during standing in each patients. Both patients never experienced recurrence of vertigo and their gaze nystagmus disappear early after operation but nystagmus under the condition without visual fixation were remained for a long time. The pattern on statokinesigrams showed the lateral sway type in the early stage and later the central type with small magnitude in each.
Vestibular rehabilitation was attempted in both patients. The patient who started e xercises early and continued the exercises for a relatively long term, was successfully treated. However, it failed to accelerate the compensation in the other patient whose exercises late and continued the exercises for short duration.

The maculo-ocular reflex related to horizontal sinusoidal linear track accelerations was studied in 21 patients with benign paroxysmal positional nystagmus (BPPN). The linear accelelations were applied by body oscillations with an amplitude of 25 cm, and frequencies of 0.25, 0.33 and 0.5 Hz. Both the amplitude and phase difference of the eye position versus the head position were measured in normal subjects and patients with BPPN. Those values were compared in both groups.
The responses in the patients with BPPN were better than those in normal subjects.
Both significant increase of the amplitude and significant phase lead were observed in the patients with BPPN. (p < 0.05)
These findings indicated that the maculo-ocular reflex in the patients with BPPN should be hyperative.

Nystagmus towards the upper ear side in both lateral head positions is usually asociated with disturbance in the central nervous system, especially with the lesion in the brain stem or cerebellar posterior vermis.
Fifty patients in whom such positional nystagmus was detected in the ENG test during the last 8 years were investigated. In only 6 cases among them was such positional nystagmus observed under Frenzel spectacles. In these patients, the continual term of the nystagmus and association with positional vertigo were surveyed retrospectively. There were 16 cases of central disturbance,32 cases of peripheral vestibular disturbance, and 2cases of congenital idiopathic nystagmus. The central disturbances included vertebrobasilar insufficiency in 6, acoustic tumor in 2, cerebellar tumor in 2, multiple sclerosis in 2. The peripheral vestibular disturbance cases included 11 of recurrent vertiginous attacks,5 of provocations-vertigo,5 of labyrinthitis induced middle ear inflammation, and 4 of sudden deafness.
Positional nystagmu s towards the upper ear side is consisted to be on important sign of the central disturbance but it may occur in the peripheral vestibular lesion. In the latter case, the positional nystagmus is associated with positional vertigo and disappears for a short time without neurological findings except positional nystagmus.

A 25-year-old-woman who had acute cerebellitis with brainstem encephalitis was reported. The patient had sudden onset of vertiginous attack and diplopia several days after a mild upper respiratory infection. Downbeat nystagmus in the primary eye position and truncal ataxia appeared and gradually decreased after the maximum stage. Further study revealed abnormal eye movement of flutter like oscillations at the stage of weakness of downbeat nystagmus and then the patient recovered to be able to stand and walk within 2 months from the onset.
The records of a series of ENG suggested that the lesion in the central nervous system should be located not only in the cerebellum but also in the brainstem. Analysis of eye movements by ENG was helpful in the judgement of the stage in the clinical course.

We report two patients with cerebral infarction, and severe vertigo at the onset, died in spite of emergency treatment.
The first patient was a 66-years-old man who had been suffering from aplastic anemia and hypertension. Though those chronic diseases were well controlled, he had a vertiginous attack of tinnitus in the right ear. Otolaryngological and neurological examination revealed the disturbance of the periperhal vestibular type without any neurological sign at the beginning. On the next day the patient died of a the second stroke.
The second patient was a 63-year-old woman, and her chief co m plaints were vertigo, vomiting and headache. A brain X-ray CT and neurological examination were almost normal 4 days after the first attack. The result of neuro-otological test showed a disturbance of the peripheral vestibular type after 12 days. However, the patient died of reccurrence of brain stroke 13 days later.
It is necessary to differentiate transient ischemic attacks from a peripheral vestibular disturbance associated with vertigo but without any other neurological sign.

Eighty seven patients with paranasal sinus disease accompanied by ophthalmologic disturbance except for injury or tumors, who had previous operation in the paranasal sinuses more than 5 years earlier, were reviwed.
The average age of the patients was 47 years. Most of them had complaints periocular swelling, impaired vision, exophthalmu and so on. About a half of them had visited other departments such as ophthalmological dept. at the beginning. The mean interval since the previous surgery in the paranasal sinus was 17 years. The focus of the visual disturbance was found in the ethmoid sinus in most cases. The prognosis was good in the patients when the surgery treatment had been carried out at the early stage within 3 weeks since the onset of visual disturbance, when the examination of the ocular fundus had revealed intact or when the origin of the disease had been a mucocele.

Formation of a pseudo-membrane localized at the palatine tonsils, and pseudo-membrane extended to the epipharynx was observed in 81% and 72% of the 38 patients, respectively. Tumescence of the cervical lymph nodes was detected in all and 44%of them had enlargement of the lymph nodes in both the axillary and inguinal regions. Skineruptions were seen in 21% of them. All showed an increase of mononuclear cells of up to 50% in the peripheral blood and in 47% emergence of atypical lymphocytes, of more than 10%. A significant increase in the EB virus antibody titer due to infection was revealed in 58% and positive Paul-Bunnel test in 33% of the patients. The diagnosis of infectious mononucleosis was confirmed by EB virus study in only 19 patients. Development of a more sensitive serological technique is needed.

Congenital cyst at the base of the tongue was encountered in 7 infants. The histopathological examination on the cystic tumors revealed the cystic wall composed of a stratified layer of the epithelium without proliferation of connective tissue and with no noticeable lymphoid cell infiltration.
This suggested thatcy stic tumors originate from the thyroglossal duct. A lateral view of the X-ray film of the pharynx was simple but very useful for its diagnosis. Furthermore, this procedure was useful for postoperative observation. Total resection of the outer part of the cystic wall was performed by laryngo-microsurgery in all cases.
Successful results were confirmed by follow-up study. This method of operation can be carried out safely and easily. It may provide a favorable postoperative state without recurrence.

We report 11 patients with eosinophilic granuloma in the soft tissue or Kimura's disease.
The patients were 8 males and 3 females. The eosinophilic granuloma may occur not merely subcutaneously but also submucosaly in Kimura's disease because the granuloma was detected at the epipharyngeal opening of the auditory tube in one case of the disease with parotid tumor. There was a tendency in the recurrence of the disease to be delayed when the number of eosinophilic leukocytes in the peripheral circulation had been reduced to the normal range after treatment. In radiation therapy,20 Gy was enough to abolish or to reduce the size of granuloma and combination radiotherapy with steroids was more effective than simple irradiation to prevent recurrence.

The dynamics of swallowing by the patients with tracheostoma were investigated using cineradiography. Two major factors caused misdeglutition. First, the laryngeal elevation for sealing the orifice of the larynx during swallowing was found to be interfered in these patients. Second, at the end of swallowing, although the larynx had returned to its resting position, a part of the bolus had not passed through the orifice of the esophagus and had remained in the hypopharynx.
By simply closing the tracheostoma, misdeglutition could be prevented. Therefore, increase in the subglottic pressure during swallowing seemed to be another important factor for the protection of the lower airway.

The esophagogram revealed a web-like formation on the anterior and posterior wall of the cervical esophagus. However, we cannot find a membranous structure through endoscopic investigation, which corresponds to the esophageal web observed in esophagogram. Anemia was markedly improved by administration of iron and the subjective symptoms were ameliorated to a great extent. However after 6 months treatment, hemorrhoidal bleeding still continued and iron therapy was discontinued. Nine months later, he again complained of paresthesis of the throat. Although not anemic, serum feritin was decreased, he was again given iron medication.

The relationship between the radiation dosage and the prognosis was studied retrospectively. The subjects of this study were 82 patients with maxillary sinus cancer who had been treated by combined therapy (surgery, radiotherapy and chemotherapy) between 1971 and 1987. During this period, the strategy of the surgery and chemotherapy was the same.
Since the prognosis of the T4 cases was poor regardless of the radiation dosage, th e T4cases were excluded from the following discussion. Sixty four cases of T3 and T2 were classified into three groups according to the radiation dosage: more than 40 Gy (8 cases), between 40 and 16 Gy (23 cases) and less than 16 Gy (33 cases). The five-year survival rate of each group was 37%,65% and 79% respectively. From theses statistics, it can be concluded that the higher the radiation dosage was, the worse the progonosis was. Besides this relationship of the dosage and the prognosis, since the unfavorable side effects of the radiation becomes worse as the dosage is increased, the radiation dosage should be reduced for the treatment of the maxillary sinus cancer.
Rediation of sixteen Gy (8 Gy preoperatively and 8 Gy postoperatively) gave us satisfactoy results for the cases below T3. However since T4 cases showed poor prognosis with this radiation scheme, futher study is required.

A 71-year-old, complained of a swelling in his right parotid area which he had first noticed one year earlier. The tumor located in his right parotid gland was detected and extracted with surrounding normal tissues by operation. The patient had no trouble 47 months after operation.
The o ther patient was an 88-year-old male who noticed a swelling at the surface of oral mucosa. The tumor located on the soft palate was removed by laser technique.
Pathological study revealed the tumors in both cases to be acinic cell tumor. Eighteen months after the first operation, the tumor had recurrend locally, and, radical operation was performed. This operation caused pneumonia because of swallowing disturbance due to advanced age. The patient died 3 months from the secound operation. No local recurrence and no metastasis to other organs was suggested by autopsy.

We retrospectively made a clinical study of 82 cases of non-Hodgkin's lymphoma which we treated between 1975 and 1988.
The onset sites were Waldeyer'sring in 48 cases, the largest number, followed by cervical lymph node in 19 cases. By stage,32 cases stage II and 22 cases stage I, the sum of which acounted for 66%. LSG classification resulted in 5 cases of follicular lymphoma and 77 cases of diffuse lymphoma. Of these diffuse type cases, the most (44 cases) were large cell type and 11 cases pleomorphic cell type. The latter had a higher death ratio. A study of surface markers by using anti-B and-T lymphocyte sera showed 15 cases of B cell type,12 of T cell type and 1 of Null cell type. Stage I cases included more of B cell type and advanced cases comprised more of T cell type. As to therapy, of the stage I and 1
E cases all of which survived, radiation therapy alone was performed in 14 and combined radiation therapy and chemotherapy in 7. Seventeen of the stage II and II
E cases, underwent combined therapy, one of which was a death case. In many of stage III and IV cases, the general condition treatment and that made it difficult to continue the treatment. Examination of 5year survival rates induced: stage I (n=22): 100%, stage II (n=32): 75.8%, stage III (n=9): 17.3%, and stage IV(n=19): 17.1%.
In conclusion, if a diagnosis has bee n made to a certain degree by otolaryngologic palpation and inspection and treatment started before making a histological or stage diagnosis, even non-Hodgkin's lymphoma can be treated as local disease, and the survival rate improved.
