Today the noise susceptibility for the acoustic trauma is seriously discussed among some otologists for the industrial workers, however, there is not yet even a clue of the reliable procedure to solve this problem.
The author described 2 cases with sudden deafness by intense noise exposure on an occasion after the long durated noise-proof good condition of hearing in a same individual. The author deduced that this noise induced deafness, suddenly appeared, should be considered as a result of an acquired noise susceptibility, which might be concerned to a disorder of the tympanic muscle function.

The author performed pansinuectomy or polysinuectomy, including external frontal operation, on 20 cases, whose maxillary and ethmoid sinuses were operated upon several years ago under diagnosis of chronic sinus suppuration and whose complaints such as nasal discharge, nasal obstruction and headache etc. were not yet cleared up. From the reoperative findings it was found that the most responsible changes were in the frontal and ethmoid sinuses.

The authors have investigated, in 270 cases of calcifications on the drum membrane, their relations with the anamnesis of otitis media, with the ages, their forms, numbers, sizes, localisations, their relations with the cicatrices and their frequencies according to occupations.
Particularly interesting are;
1) Half of the cases have no anamnesis of otitis media.
2) In youth, calcifications are found very rarely.
3) Most of calcifications are found in the upper half of the Pars tensa and none in the Pars flaccida.
4) Most of calcifications are accompanied by the cicatrices and only few are not.
5) Calcifications are found very often among the workers in the coalmines, especially those working in the pits.
From the results, the calcification is supposed to have very little with otitis media, but very much with the bodily effects caused by the bad conditions of labor plus physiological processes, which play an important part.

275 patients of tuberculosis, to whom Streptomycin was intramuscular injected, were observed and the result was as follows.
1) The hearing impairments was found in 14.9% and the Tinnitus was found in 22.0%.
2) Here was no difference about the Frequency of auditory disturbances between the patient of normal hearing and of the hard of hearing of high tone before use of Streptomycin.
3) Ototoxity of combined Streptomycin was very smaller than dihydrostreptomycin.
4) The appearance of auditory disturbances had no parallel relation with other side reactions.
5) Hearing loss was seen at C⁶, C⁵ or C⁵. C⁶ in the early stage of Streptomycin impairment.
6) The hearing impairment in the presence of the compromised renal function was very frequent and high degree.

Auditory disturbances after Streptomycin therapy of 164 patients were observed and the result was as following.
1) Here is many patients who suffering from hearing impairment of broad range and of high degree even when used in small doses.
2) Audiogram showed abrupt form, gradual form and flat form and many of them were symmetrical on both side.
3) Hearing loss at speech range of many patient were over 30 db on an average.
4) The deafness and hard of hearing, by whom recovered from meningitis tuberculosa, was 88.8%.

Observing the hearing disturbance from the tympanic membrane retraction and the state of the Eustachian tube catheterisation. The A type considered as normal hearing curve showed good insufflating condition and most cases did not showed the tympanic membrane retraction. The bad hearing curve, often observed as the employed years increased, showed the worse insufflating state in the group of 11-20 years employment and it was worse in the group of more than 21 years employmemt.
It is to be noted, however, the D type of more than 21 years employment showed bad insufflating state and the cases of not having tympanic membrane retraction increased compared with the group of 11-20 years. Generally speaking, the increased years of employment brought the state of bad insufflation and increased the tympanic memsbrane retraction.

The hearing disturbances of 555 workers at a steel mill were investigated, classifying the groups by noise intensity and employed years.
1) 70 db group: 54.7% of the employees working less than 5 years showed normal hearing curve and this curve decreased to only 2:4% in the employees working more than 21 years-the dip type increased to 69% and 7% showed the descending type of bad hearing curve.
2) Over 90 db group: within 5 years of employment, only 4.2% showed the normal hearing curve and the dip type was recognized in 54.2%. The employment of more than 21 years decreased the normal hearing curve into 1.8% and increased the dip type to 45.5% and the descending type to 23.6%.
As the employed years passed, hearing disturbance was caused by 70-79 db and 80-89 db noise and the progress or disturbance remained at a certain point while 90 db noise accelerated the progress of hearing disturbance.

In the otorhinolaryngological region, extramedullary plasmacytoma is very rare and the reports of this tumor, especially growing in the nasal cavity or on the nasal septum, are only a few.
In this case, the tumor disseminated in the nasal cavity and was diagnosed as plasmacytoma by histological examination. This tumor was clinically benign and never metastasized. It was only surgically resected and the postoperative course was favourable.

Sarcoma originating in the larynx is a very rare disease. Reference to the literature both domestic and foreign shows that the rates of occurrence of laryngeal carcinoma and sarcoma are indeed 90%: 1%.
The case the author has here reported is worth mentioning in that it occurred in a female aged 16. It goes without saying that diagnosis needs sufficient attention to the subjective and objective symptoms in the early stages as well as repeated histo-pathological examinations.
The author believes that in its treatment the administration of anticarcinomatics is indispensable together with neck dissection in addition to the extirpation as hitherto reported.

Die Verfasser haben einen Fall von hysterischer Aphonie mitgeteilt, die bei einer 32 jährigen Frau die Kehlkopfbilder von beiderseitiger Recurrenslähmung zeigte. Von ihrer Erfahrung, in der die Verfasser die Patientin mittels der Narkosentherapie (intravenöse Injektion von Isomytal) zur Heilung brachten, möchten die Verfasser die Einfachheit und die Vorzüglichkeit diesser Behandlungsmethode betonen.
In Bezug auf die Kausalität zwischen der Laryngitis und der hysterischen Aphonie möchten die Verfasser so auffassen, dass das Vorhandensein einer Laryngitis beim Auftreten von hysterischen Stigmata die Bedeutung als Locus minoris resistentiae hat.
Die Verfasser haben auch einen Ueberblick der 57 Fälle solcher Krankheit in Japan gemacht.

Seven cases of the hypertrophical vocal cord disease (their occupation were 4 teachers, 1 kindergartner and 2 leatherworker) were observed in the ovarian functional insufficiencies (1 case of each habitual abortion, dysmenorrhea, hypomenorrhea, bilateral ovariectomy and 2 cases of each uterus hypoplasia, climacteric psychosis).
It is well understood that the direct cause of it will be resulted from their excessive speaking and chronic chemical stimulation.
From the points of gynecological findings, history of cases and medical treatments, not only the local therapy but ovarian hormone therapy worked well in this disease.
It seems that the ovarian functional insufficiencies may not the direct cause of it, but they will predispose to it.

It is not seldom to find the difficulty in the removal of foreign body under autoscope even when X-Ray examination shows its existence in the esophagus or trachea.
A 14 year-old boy aspirated a pencil cap made of aluminum into his right bronchus.
At first, the foreign body couldn't be clearly observed by autoscopy. Therefore, inserting a metal tube into the bronchus as the contrast to show the right location of the body under roentgenogram and bronchoscope, the removal was made successfully.

Eight cases of facial neuralgia were treated by the sympathetics blockade, and four were cured completely and the another four improved. An effective mechanism of the sympathetics blockade was considered among the trigeminus, sympathicus and periferal circular systems in their pathologic condition.
