The author attempted to inspect three cases of skull base fracture caused by traffic accidents, about their recovery. Examined next symptoms: 1. hemorrhage from the ears, nose and mouth 2. consciousness 3. change in toe pupils 4. tendon-reflex 5. spinal hemorrhage 6. fractured line appeared on X-ray photograph 7. efflux of cerebrospinal humor through the nose and ears, etc. 8. symptoms remained a. headache, b. hypacusia, c. noise in the ear, d. vertigo, e. anosmia, f. facial nerve paralysis, etc. One of these cases was very serious, the patient remained unconscious for more than 10 days. The recovery in such serious cases is quite rare.
It is said, that diphtheria in nasopharynx is rare. But the author suppose, that it is due to the difficulty of observation for nasopharynx, especially in infants. Observed 153 cases of diphtheria during 18 months and obtained next results. 5 cases are affected only in nasopharynx, 35 cases both in nasopharynx and the other places. 20 cases are supposed to be affected in nasopharynx.
For the past 5 years the authors have treated 77 cases of cancer of the larynx by the operative procedure. In 7 cases laryngo-fissure, in the other cases laryngectomy were performed. In 70 laryngectomized cases, 32 cases were intrinsic, 38 cases were extrinsic cancers and 8 cases had so extremely advanced that the places of the out-break were indistinct, 5 cases in which a part of cancer had involved to the thyroid gland after having had broken the thyroid cartilage. In these cases there were many far beyond the indication appointed by Crowe, but the authors could dispose of them only by median line incision. From these experiences the authors concluded that they can by this method dispose of effectively even those far beyond what Crowe himself stated as indication for this operation, and at least by some experiences they can easily dispose of such cases as can be done by the usual method of operation by Gluck, Seroensen and so forth. The authors have described few noteworthy points on the operation.
1) For the past 10 years, 73 cases of otogenous intracranial complications were treated, in which 48 meningitis, 34 sinus thrombosis and 6 brain abscess were observed. 2) The prognosis of meningitis was better in cases due to chronic otitis media than that of acute. The former were 15 cases, in which 8 cases were cured, while the later were 33 cases, in which 8 cases were cured. 3) For the spinal drainage, Tanaka-Oda's method (continuous drainage under the definite positive pressure) were employed with excellent results as well as laminectomy. 4) In these 108 cases of meningitis (1922-1936 60 cases; 1937-1946 48 cases), 32 cases (29.6%) were cured.
To select those who have staggers caused by labyrinth, it has been measured usually, durable time of the “Post-rotationary” nystagmus. But when we observe the said nystagmus with naked eyes, our subjective view very much interferes with our final conclusion, and it has been said, that various conditions affect the durable time of the nystagmus in animal experiments. Consequently I have observed the following effect in man. (1) The differences based on the subjective view of the examiner. (2) The visual angle of the examined. (3) Meal. (4) The length of the recess between two measurements. (5) Daily changes. (6) Age. (7) The rightward rotation and the leftward rotation. And so I wanted to select those who have staggering tendency upon the result of my above experiment. But I have found the nystagmus to be unsuitable as a standard for discovering those who have such tendency. Therefore, I observed directly the duration of selfconscious staggers occasioned by giving rotationary stimulus, the vestibular vegetable nervous reflex caused by putting the head in motion while rotation, and the vestibular-spinal reflex caused by sudden change of the head position at the end of rotation I have been convinced of the suitability of the last method for the purpose.
