Ten cases of brain tumor were observed from three otological points of view ----- pure tone audiometry, speech audiometry and auditory adaptation.
The phenomenon of marked adaptation and reduction of speech perception strikingly disproportionate to threshold for pure tones, was most conspicuous when the site of lesion is in the first neuron. Then the author presumed that marked adaptation is one of the important contributing factors to the reduction of speech discrimination. In cases of supratentorial tumor, the same phenomenon has been observed by the direct or indirect application of pressure on brain stem, and there was no close relationship between the side of brain lesion and the impaired ear in auditory acuity.

In the cases complicated with the vocal cord paralysis following thyroidectomy, 3 cases with a full healing, which were interesting from the standpoint of the vulnerability of the recurrent laryngeal nerve at the operation and in the laryngoscopic and electromyographic findings of the intrinsic laryngeal muscles during the period in the paralysis, were reported.
For the vocal cord paralysis following thyroidectomy, the next conclusions were obtained by recording the electromyography of the intrinsic laryngeal muscles with the lapse of time after the operation.
(1) Although the vocal cord appearently shows the fixation, the intrinsic laryngeal muscles at the paralytic side are to be in various conditions, which can have various influences on the laryngoscopic findings.
(2) Of factors that have influences on the fixation of the vocal cord, not only the nerve paralysis, but also the unbalance of the activity of the intrinsic laryngeal muscles and the disturbance of the arytenoid joint must be considered.
(3) Electromyography of the intrinsic laryngeal muscles is significant in observation of the clinical process and judging the prognosis of the recurrent laryngeal nerve paralysis.

A seventeen year-old female was admitted on Junuary 1963, who has complained of painless swelling of the left upper jaw, which was recurrent new growth in two years after the partial removal of the left upper jaw at a hospital.
The tumor was removed by a total resection of the left upper jaw. Microscopic examination revealed a osteofibroma or ossifying-fibroma.
In the postoperative course of one year, the state of wound is satisfactory.

One hundred and six cases of several diseases of the ear, nose and throat, such as allergic rhinitis, acute sinusitis, acute rhinitis, serous otitis media, acute pharyngolaryngitis, acute tonsillitis, and others were treated with a new antihistamic drug “Entra”.
Effective results were obtained in about 80% cases of each disease. Though some byeffects were observed in about 10% cases of the series, those symptoms were slight and easily controlled.

In this experiment only the difference of respiratory pattern compared with alae nasi muscle was discussed.
Matured rabbits, given local anesthesis, were used for investigation.
Although it's recognized that electrical activity of intrinsic laryngeal muscles is controlled by C. N. S. as other respiratory muscles and was classified as though it belongs to the only accessory respiratory muscles such as alae nasi muscle, but the experimental findings were showed that there were numerous contradiction with classic theory to physiological classification of accessory respiratory muscles.
As regards nervous control, intrinsic laryngeal muscles were well seen to hold more intimacy with activity of central regulation than alae nasi muscle.
