A review has been made of the histopathologic features of inner ear degeneration caused by viral endolymphatic labyrinthitis due to maternal rubella, mumps, measles and unidentified viruses in the adult. Some comparisons have been made with genetically-determined degenerative regressive deafness in certain animals and humans, also with degenerative changes due to toxic drugs in the human and partially obstructed circulation in experimental animals.
Certain features have been illustrated which appear to differentiate changes due to viral endolymphatic labyrinthitis from those caused by ototoxic drugs or sudden impairment of circulation.

In general, radical neck dissection has been performed for malignant tumor of the neck, for example, malignant struma, primary or metastatic tumor. So far, the performance of operation was very difficult when the infiltration of tumor has spread over the wall of main carotid artery. Ligation or resection of the carotid artery causes brain damage in high average. Recent development of vascular surgery has made such an operation feasible. This paper describes the technique of reconstructive surgery of carotid artery. One of the present authors (K. I.) devised the blood vessel suturing apparatus that has given the ideal anastomosis. This machine has been successfully used 419 times in 273 clinical cases of various vascular surgery. There has been no complication. This machine is especially useful for the reconstruction of the carotid artery because the time of blockade of the vessel can be very much saved, and the finding of the anastomosis is ideal, being no fear of postoperative thrombosis of the suture line.
In our clinic, the vascular reconstruction with radical neck dissection has been given to 23 cases of malignant tumor of neck and 5 cases of carotid body tumor have received vascular surgery with extirpation of tumor. The operative procedures of vascular surgery consisted of excision and insertion of graft, excision and simple anastomosis, patch graft with autovein, and direct suture of side wall of blood vessel. There were no operative death. Autovein graft was used for the insertion from common carotid artery to internal carotid artery, on the other hand, the synthetic graft was used only for the insertion at the common carotid artery. Detailed technique and secrets of reconstructive surgery in the radical neck dissection were described.

There are many kinds of benign tumors occuring in the tongue, but leiomyoma is much rarer.
A case of leiomyoma of the tongue in an infant was reported. The patient complained of the tumor in the tongue and speech disorder. The tumor was removed easily under general anesthesia.
Histopathological examination revealed leiomyoma.
Neither recurrence nor metastasis was seen one year after the operation.

A nasal papilloma occurring from the antrum of a 20 years old male and its histological findings were examined.
A histochemical finding seems very interesting that the almost epithelial cell of this tumor has abundant glycogen except basal layer.

114 cases of foreign bodies treated in the Kyushu Welfare Pension Hospital Otorhinolaryngological Clinic, from 1955 to 1966 were reviewed.
12 cases were in the trachea and bronchus, 43 in the esophagus, 29 in the pharynx, 12 in the nasal cavity and 18 in the external auditory meatus.
Foreign bodies in the trachea and bronchus and in the esophagus were predominantly in the case of male: the ratio of male to female was 1.5: 1. The age range of this series was almost under 5 years.
The material of foreign bodies in the trachea and bronchus was varied, but in the esophagus coin in many cases.
Some rare cases of foreign bodies were referred to: tulcum powder in the trachea and bronchus, sweet potato dumpling and a dental prothesis in the bronchus and double coins in the esophagus.

Benzydamine, a nonsteroid antiphlogistic was used with the good results in 30 cases of the otolaryngological disease. It appeared to be the most effective as an anodyne, especially after tonsillaroperation. It was also effective for the treatment of catarrhal otitis media. But for the treatment of nasal allergy the expected result was not obtaind.

Verff. beobachteten einen Fall von Schwerhörigkeit und Schwindel nach elektrischem Schlag. Ein 33 jähr. Mann erlitt bei der Arbeit durch elektrische Berührung (250 V, 170 Amp) einen Schock und litt seitdem unter Schwindel, Nervenschwerhörigkeit und Ohrensausen und zwar letzteres auf dem linken Ohr. Es handelt sich bei dem Patienten nur um den elektrischen Schlag, ohne hinzustürzen. Er erlitt daher keine äusseren Verletzungen.
Die obengenannten Symptome hielten einige Monate an. Die Nervenschwer-hörigkeit schritt mit der Zeit fort. Schwankschwindel und Nausea wiederholten sich mehrere Male.
Ein halbes Jahr später trat Taubheit des linken Ohres ein. Kein Schwindel mehr; jedoch wurde elektronystagmographisch spontaner Nystagmus nach der linken Seite hin registriert.
Bis jetzt wurde es über Hörschädigung und Vestibular-Störung durch elektrischen Strom von vielen Forschern berichtet. Es war aber schwierig, die verschiedenen Auswirkungen eines elektrischen Schlages, besonders den Innenohrschaden, zu erklären. Verff. kamen auf Grund der obengenannten Erfahrungen und vieler anderer Berichte zu der Erkenntnis, dass elektrischer Strom Hypertension, Elektrolyse, Wärme, Gefäss-und Gewebestörungen, sowie Degeneration und Nekrose in Hirnstamm und Innen-und Mittelohr verursachen.

On 145 cases which complained chiefly of the olfactory disturbance, general observation was carried on.
And then, the relationship between the pneumatisation of parasinus of 50 patients suffering from chronic sinusitis and of 25 patients suffering from olfactory neurosis and their olfactory disturbance was observed and considered by means of roentgenograms.
The results were as follows:
1) As for the extent of olfactory disturbance, anosmia was of the highest percentage (60.7%), while as for the kind of disease, chronic sinusitis had a majority (53.1%).
2) Common cold or the inflammation of the upper respiratory tract often became the cause of olfactory disturbance.
3) Patients with hypotension had the tendency to cause olfactory disturbance.
4) No remarkable change of serum-Ca & K was noted.
5) The function of the autonomic nerve was generally stable.
6) Pneumatisation of the maxillary and the ethmoidal cavities of the patients suffering from chronic sinusitis with olfactory disturbances and of those suffering from olfactory neurosis was under-developed in many cases, and few well-developed cases were found in this study.
7) Patients with olfactory disturbances occupied a high percentage in the cases of under-developed pneumatisation in the frontal sinus.
