    1) Following excision of the carotid sinus nerves of the rabbit blood pressure increased by an average of 29mmHg, and vasoconstriction of the stria vascularis was histopathologically observed, without any destructive changes.
    2) Unilaterl or bilateral removal of the superior cervical ganglion was followed by the vasodilatation of the stria vascularis, appearance of nubecula in the endo- and perilymph and swelling of the cells in some organs of Corti.
    3) In the control animals acoustic stimulation by a 110 phon white noise for one hour daily for 10 successive days caused no cochlear lesion, while in the treated animals it resulted in the destruction of the hair-cells and other structures of the organ of Corti and the stria vascularis. This acoustic trauma was produced bilaterally in the case of unilateral excision as well, and was marked at the second turn.
    4) The reduced C.M. potentials of normal rabbits on exposure to a 110 phon white noise for 30 minutes was restored to normal in 15 to 20 minutes, but in the case of bilateral gangliectomy only a small amount of recovery was observed. The unilaterally gangliectomized animals similarly showed poor recovery on the affected side, with nearly the same recovery on the opposite side as the normal subjects.
    5) These results apparently indicate that increased noise susceptibility is caused by the surgical removal of the carotid sinus nerve or superior cervical ganglion.

    The present work was designed to elucidate a frequency of optokinetic nystagmus in normal subjects.
    Five healthy adult men and five women with normal vestibular function were examined with regard to horizontal and vertical nystygmus by rotating the optic cylinder, which was rotated for 180 seconds with angular accereration 1°/sec2. In both of horizontal and vertical nystagmus, the frequencies of nystagmus reach at the maximum value between 40°/sec and 100°/sec, and then, maintain this level or decrease gradually.
    By analysing the frequency obtained, the eqation of critical ellipse for the horizontal nystagmus or for the vertical (downwords or upwords) nystagmus in any subject was made.
    According to the author's opinion, it seems to be useful for the examination of the eqilibrium function of patients to survey horizontal and vertical nystagmus by rotating the optic cylinder and to evaluate the result by putting the obtained data on the patient into the above-mentioned formula.

    Clinical and audiological observations were made on 78 cases with recent history of head blow.
    In addition to conventional pure tone audiometry, Békésy-type audiometry, distorted speech test using high or low pass filter for Japanese monosylabic words and binaural hearing test were employed for further evaluation of hearing acuity.
    EEG and vestibular test were also performed in some cases.
    An attempt was made to clarify hearing impairments following head injury as follows;
    1) middle ear type
    2) labyrinthine type
    3) retro-cochlear type
    4) middle ear & labyrinthine type
    5) labyrinthine & retro-cochlear type
    6) middle ear & retro-cochlear type
    7) middle ear & labyrinthine & retrocochlear type

    Ultrasonic diagnosis of the maxillary diseases by reflection method was investigated.
    The following results were obtained.
    1) The applicable frequencies of the sound wave are 5 megacycles per second (gain: maximum, pulse breadth: 5.0-6.0μs) or 2.25 megacycles. (gain: maximum, pulse breadth: 2.0μs)
    2) The mean of attenuation constant of the anterior wall of the maxillary sinus is 14.8±4.2db and it increases in proportion to the bone thickness.
    3) As the normal maxillary sinus involves the air, the ultrasound can not reach to the posterior wall. The echogram showed no intrasinusal echo except the multiple echoes from the anterior wall.
    4) The echogram of sinusitis showed the bottom echo, if the sinus is filled with exsudat, polyp or inflammatory tissues. But the detection of the bottom echo depends chiefly on the angle ratio of the anterior and posterior wall of the maxillary sinus and on the distance between them.
    5) The benign tumors and postoperative cystes showed only the surface and the bottom echoes. On the other hand, carcinoma and sarcoma of the maxilla showed irregular echoes reflecting from the malignant tissues.
    6) The spreading area of malignant tumors determined by this method.
    7) The radiation effect on malignant tumors investigate by comparison of the echograms before and after radiation.

    The laryngeal primary tone is modified by the resonance cavity (mouth, nose, throat) and becomes the individual voice which we can hear.
    A method of the qualitative research of the primary tone was devised.
    The differences of the spectrum pattern (Section of Sona-Graph) between the vowel “a” and whispered voice “a” were measured and this difference was regarded as spectrum pattern of primary tone.
    The spectrum pattern of various qualities of voice (loud and natural voice, male and female voice) was examined, In loud and male voices, spectrum pattern had many overtone than the natural and female voices, and individual over tones of the former were taller than the latter.
    The spectrum pattern of the primary tone which was taken from the patient by probe-tube microphone during surgery and spectrum pattern of the former method were compared.
    A general similarity was seen.

    It has been reported that the deficiency of V.C and stomatis has some relation.
    The author measured V.C in the whole blood of the 60 cases with at. ulcerosa including st. aphtosa.
    All V.C of 33 normal cases asa control group were measured by the same procedure.
    The results of the both group were statisticaly studied and compared.
    All blood V.C of the control group and the cases of at. apatosa showed averages of 0.8I±0.245 mg% and 0.79±0.322mg%. The difference between both averages were not considered to be significant from the statistical point of view.
    In experimental orale ulcer by Ca. albicans (by rabbits), blood V.C and V.C in the ulcer was increased.
    Biosynthesis of V.C in the rabbit bodies is possible, wheras it is impossible in human bodies, therefore it is concluded that on the healing of ulcers V.C. has some significance.

    Four cases of Treacher Collins syndrome, three brothers and the eldest brother's daughter in the same family, were reported. The characteristic fish-like facial appearance and the bilateral conductive ductive deafness were common findings in all of them.
    In the first case, a male aged 37 years, the hypoplasia of the maxillae and mandible, anti-mongoloid inclination of the palpebral fissures, myopia and strabismus divergens were found. His auricles were flat and positioned unusually low. Roentgenologic examinations revealed highly inhibited pneumatisation, especially absence of the antrum, unusually large frontal sinuses and a small sella turcica. Average hearing loss in speech range was 52.50db on the right ear and 53.75db on the left.
    In the second case, a male aged 35 years, the development of the facial bones was more disturbed than in the first case. The anti-mongoloid obliquity of the the lid axis, strabismus divergens, high palate with a fistula on the midline, nonprominent crura antihelicis, congenital fistula on the auricles and narrow external auditory meatus were noted. Roentgenologic findings of ears were similar as in the first case. Audiometric examinations revealed conductive deafness of both ears: hearing loss was 47.50db on the right and 52.50db on the left.
    In the third case, a male aged 30 years, the obliquity of the lid axis, strabismus divergens, large frontal sinuses, high palate, macrostomia, macrog- lossia and malocclusion of the teeth were noted. His hair grew in the form of tongue-shaped process of the hair-line extending towards the cheeks. Otological examinations revealed a lower than normal position of auricles, narrow and curved external auditory meatus, underdevelopment of the antrum and mastoid cells and conductive hearing loss of 41.25db on the right and 52.50db on the left.
    The fourth case was a daughter of the first case, aged 9 years. Typical facial features, such as disappearance of the frontonasal angle, micrognathia, hair-tongue on both cheeks, were noted. The left microtia with atresia auris and the right with extremely narrow external auditory canal were remarkable in this case. Roentgenological examinations showed markedly inhibited pneumatisation of the temporal bone with absence of the left tympanic cavity. Hearing loss was 40db in both cars.
    In the second and third cases, tympanoplasty (Wullstein's the third type) was done on bilateral ears and hearing acuity was improved in each ear. The main operative findings of these four ears were as follows:
    1) unusually large suprameatal spine,
    2) abnormal extension of the auricular cartilage into the osseous meatus,
    3) absence of the antrum and narrow attic,
    4) absence of the incus and slight or moderate malformation of the malleus and stapes,
    5) absence of stapedial muscle,
    6) no appearance of the chorda tympani in the tympanic cavity associated with abnormal course of the facial nerve,
    7) no inflammatory process, no ankylosis, no adhesion.
    Pathogenesis, heredity, clinical symptoms and operative findings in this syndrome were discussed in detail. The authors emphasized that the hearing loss in this syndrome should be improved by tympanoplasty.

    Statistical observations were carried out with the findings of 52 ears operated on congenital malformation of conductive apparatus and several interesting findings were reported and discussed in connection with the embryological views of external and middle ear.
    As to the hearing improvement by operatoin, it was revealed that the classical fenestration yielded the most satisfactory result compared with tympanoplasty or stapes surgery.
    The major points are as follows:
    1. Embryological aspects:
    Operations were performed on the cases showing air-bone gap of more than 30db.
    a) Even the cases with apparently normal ear canal occasionally had stapes malformation or stapes fixation.
    b) Most of the cases with abnormal ear canal showed malformation of malleus and incus or ankylosis between malleus and incus.
    c) Separation of incudo-stapedial joint was sometimes noticed in these cases irrespective of presence or absence of abnormality of ear canal. The above operative findings coincide with embryological views; malleus and incus are derived from the first branchial arch (Meckel's cartilage) and stapes is from the second branchial arch (Reichert's cartilage).
    2. On operation method:
    a) Fenestration is highly recommended for hearing improvement in the cases with normal cochlear function.
    b) Stapedectomy is also indicated in the cases with the slightly impaired cochlear function but with normal ear canal.
