1) By means of a biocular iriscorder, the pupillary response in patients with Bell's palsy was examined for the purpose of analysing their autonomic nerve functions.
2) Subjects were 68 patients of new Bell's palsy who recently consulted Kitano Hospital, Osaka, Japan.
3) In comparison with the mean value of the pupillary response in normal subjects, 18 patients of Bell's palsy were within normal ranges in all the test results, although, abnormal autonomic nerve functions were observed in 15 cases. Furthermore, 26 showed abnormal functions in some test results, and in 9 other cases, interpretation of data was impossible.
4) In abnormal cases or cases with some abnormal test results, temporal paralysis was observed in a large percentage, although, some of these patients had a tendency for prolonged recovery more than 60 days after the onset.
5) These results show that there were many cases of Bell's palsy with abnormal autonomic nerve functions. In the treatment of Bell's palsy, one should keep in mind the control of their autonomic nerve functions and the delivery of medicine should be made especially in early stages of palsy.

Evaluation of the latency of the waves in the auditory brainstem response (ABR) in 133 patients with vertigo and/or dizziness was made and some comments were added. 1. The latency of the first wave was prolonged in the patients diagnosed as having Meniere's disease or central vertigo with hearing impairment in high-pitched ranges. 2. The latency of the fifth wave was prolonged in the patients diagnosed as having central vertigo or as being in a “late state of head trauma”. And the degree of prolongation of the fifth wave was not always consistent with the degree of prolongation of the first wave. 3. The interval between the first and fifth waves was significantly prolonged in the patients who were diagnosed as having central origin vertigo or as being in a “late state of head trauma”. Making use of the interval between the first and fifth waves was the most appropriate when diagnosing central dysfunction.
In conclusion, at the otoneurological examination the ABR is one useful test for the differential diagnosis of the lesion in the brainstem, either due to a mass lesion or to a degenerative lesion.

The height (H) and breadth (B) of the inferior nasal meatus were evaluated using polytomographic frontal sections at 1, 3, 4 and 5cm from the nasion. Normal adults, 45 males and 40 females, were studied. Neither H nor B showed significant differences between the right and the left sides. Both H and B were larger in males than females with statistically significant differences. The difference becomes larger at the posterior portion of the nasal cavity. Correlation between H and B at the same section was small. Individual variation of H was larger than B and the variation tends to become smaller at the posterior portion of the nasal cavity. The inferior nasal meatus is made of the inferior concha, palatine bone and maxilla. The inferior concha and palatine bone evolve as a part of the maxilla as far as the facial development is concerned. Since the lateral and the inferior boundaries of the inferior nasal meatus belong to the different functional units of the maxilla, the height and breadth are influenced by different factors. The development of the inferior nasal meatus is thus a part of the facial development.

Plasmacytoma in the nasal cavity and paranasal sinuses is quite a rare disease in our country as well as abroad. We experienced three cases of this disease in Kyoto University Hospital in the past five years.
A 68-year-old man visited the ENT clinic of our hospital with complaints of unilateral nasal obstruction and habitual nasal bleeding from the same side. On examination he was found to have an obvious appearance of a malignant tumor in the nasal cavity and paranasal sinuses. Histologic examination of the lesion showed plasmacytoma.
Two other cases of plasmacytoma in the maxillary sinus secondary to multiple myeloma were seen in the Department of Internal Medicine.
These three cases are thoroughly compared to show several differences in clinical features.

Our experience with surgical treatment of primary hyperparathyroidism is described. Five patients who were recently operated on, were composed of three males and two females, ranging from 24 to 66 years in age. Besides hypercalcemia, each patient had a main clinical manifestation, such as pathological bones (2 cases), peptic ulcer (2 cases) and ureterolithiasis (1 case). As the methods for localizing parathyroid gland tumors, ²⁰¹T1 scincigraphy combined with ¹²³I-Na scincigraphy or ⁹⁹TcO₄-scincigraphy, and computed tomography (CT) were diagnostic. Histological examinations showed adenomas in four cases and hyperplasia in one. Postoperatively, hypercalcemia reappeared ten months after surgery in a patient with hyperplasia, and hypocalcemia developed for a long time after surgery in a patient with pathological bones.

A 74-year-old man with a firm asymptomatic tumor in the upper left lateral neck visited our department on March 5, 1979. At surgery under local anesthesia, it was confirmed that the tumor originated from the vagus nerve. The tumor was removed together with the vagus nerve. The neurinoma of Antoni type A and B was diagnosed on microscopic tissue examination. Virtually no symptom or sign was observed post-operatively except for tachycardia of short duration and persistent hoarseness.
Neurinoma of the cervical vagus nerve is a rare growth. Statistical observation was made on 35 cases, including ours, reported in Japan from 1926 to 1980. Our comments on neurinoma of the cervical vagus nerve are as follows.
1) The age at diagnosis ranged from 23 to 74 years with an average of 45 years.
2) The incidence was slightly higher in men than in women.
3) The incidence was considerably higher on the right side than on the left at a ratio of 2:1.
4) It is relatively difficult to make a correct preoperative diagnosis of this tumor.
5) The statistics show better prognoses for complete removal of the tumor together with the vagus nerve than intracapsular removal.

By a combination of “separation of the visual field” and “ the overlapping method”, the author has studied the optokinetic nystagmus induced by foveal vision and peripheral vision as well as the optokinetic nystagmus in artificial hemianopsy. Optokinetic response was recorded by DC-ENG in five healthy adults, to whom constant speed stimulation (10-120°/sec.) was administered using a projection-type optokinetic stimulator. Results obtained are as follows.
(1) The nystagmus induced by foveal stimulation begins with a slow phase, whereas that induced by peripheral field stimulation begins with a quick phase.
(2) With foveal vision the slow phase velocity of nystagmus, at low stimulus speeds, is equal to the speed of the target. At higher speeds the slow phase velocity falls below that of the target speed. With peripheral vision, the slow phase velocity is often slower than the speed of the target even in the slow speed range.
(3) Peripheral vision supports foveal vision subsidiarily, and this supporting effect is more evident in the high speed range of optokinetic nystagmus.
(4) Temporal and nasal hemianopsies have the same properties against optokinetic stimulation.
(5) There is no essential difference between the optokinetic nystagmus induced by nasotemporal and temporonasal stimulations.
(6) When foveal vision is reserved, there is no remarkable difference between the optokinetic nystagmus in hemianopsy induced by foveopetal and foveofugal stimulations.
(7) In the case of hemianopsy whose foveal vision is involved, the nystagmus during foveofugal stimulation is very fine and irregular, in contrast to the nystagmus during foveopetal stimulation which is well induced almost comparable to the normal eye.
(8) Foveal vision is very important for formation of the slow phase of optokinetic nystagmus.
(9) Foveopetal movement of an image in the peripheral retina is very important for formation of the quick phase, and is stronger than foveofugal movement in the peripheral retina as a stimulus to attract the eye.

A considerable amount of literature exists on the morphology of the ciliary movement in postoperative maxillary cysts as well as chronic paranasal sinusitis, but it is still necessary to study the function of ciliary movement in discussing the pathology of the paranasal mucosa.
We observed the function of ciliary movement in postoperative maxillary cysts as well as in chronic paranasal sinusitis by a direct and quantitative method. Additionally, the effect of telbutalin sulfate on the function of pathological ciliary movement was examined. The following results were obtained.
1. The existence of ciliary movement in the mucosa of the maxillary sinus and nasal polyp was noted in all the cases with chronic paranasal sinusitis.
2. The existence of ciliary movement in the mucosa of the postoperative maxillary cyst was noted in 2 of the 3 cases.
3. In respect to the site of ciliary movement, a comparatively small difference between the mucosa of the maxillary sinus and that of the nasal polyp was noted in the case of chronic paranasal sinusitis, while a large difference was noted in the case of postoperative maxillary cyst.
4. The activating action of telbutalin sulfate on the reduced function of ciliary movement was noted in the case of chronic paranasal sinusitis or postoperative maxillary cyst.

Clinical investigations of Clindamycin-2-phosphate, a new clindamycin derivative, was performed with the results which led to the following conclusion.
1) Results of clinical treatment: When Clindamycin-2-phosphate was intramuscularly injected to 38 cases of representative diseases in the otorhinolaryngologic field, clinical results were excellent in 18 cases, good in 14 cases, fair in 3 cases and poor in 3 cases. When the excellent and good cases were considered together, clinical response was present in 32 cases, 84.2per cent.
2) Side effect: No side effect was found with intramuscular injection of Clindamycin-2-phosphate.
