JOURNAL FREE ACCESSOn the basis of electromyography, radiography and ultra-high speed cinematography, vocal cord paralysis can be classified into three groups. In the first group (paralytic type), regeneration can not be expected and the mobility of the vocal cord is completely lost. In these cases, no electrical activity is found. Marked atrophy of the vocal cord on the diseased side is noticed. Glottis is opened during phonation and the vibration of the vocal cord, is irregular, asymmetrical and markedly weak. In the second group (paretic type), normal neuromuscular unit voltage is recorded. Atrophy of the paretic vocal cord is very slight and the mobility of the vocal cord is slightly observed. Glottis is closed during phonation and the vibration of both vocal cords is regular and symmetrical or asymmetrical. The voice is not so hoarse. In the third group (pending type), the possibility of recovery remains. In these cases, abnormal electromyograms such as fibrillation voltage are observed. The atrophy of the muscles on the affected side is moderate. Glottis is insufficiently closed during phonation, and the vibration of the vocal cord is irregular. Many of these cases will belong to either of the former two types about one year later from the attack and a few of them will recover.View full abstractDownload PDF (2161K) -

JOURNAL FREE ACCESSIn this paper, the clinical results of tympanoplasty in 21 cases of tympanosclerosis and the propriety of this operation was discussed. The following conclusions were obtained.
1. Otoscopic observation revealed big perforation of the ear drum with small amount of discharge which was very favorable to tympanoplasty. But the results obtained was not satisfactory.
2. In the cases with negative bone conduction threshold and moderate hearing loss, the results of the surgery were especially unsatisfactory.
3. The result of type III tympanoplasty was most satisfactory. Therefore it was concluded that incus should be removed in the procedure of the surgery and the sclerotic tissue around the stapes should be removed thoroughly.
4. Stapedectomy or fenestration operation should not be done primarily in tympanosclerosis.View full abstractDownload PDF (590K) -

JOURNAL FREE ACCESSPrimary squamous cell carcinoma of the thyroid gland is rare and high malignant neoplasma. During past six years, we treated 87 cases of thyroid carcinoma in our clinic, among them a case, 43-years-old female, of primary squamous cell carcinoma was reported herewith.
She had been aware of the left thyroid tumor since nine years with silent symptome. Recently, this left thyroid tumor began to grow in size aggressively with dyspnea and hoarseness in a few days. Histological examination revealed follicular adenocarcinoma showing anaplastic medullary growth in the primarily extripated struma and poorly differentiated squamous cell carcinoma in the local recurrent mass. Metaplasia from follicular adenocarcinoma to squamous cell carcinoma was supposed as the pathogenesis of this case. Radiation therapy and chemotherapy of 5Fu and BLM were not effective.View full abstractDownload PDF (6288K) -

JOURNAL FREE ACCESSA case of chronic encapsulated subperiosteal abscess in the orbit as a complication of frontal and ethmoidal sinusitis was presented.
34 years old man with a history of moderate proptosis of the left side of 10 months duration was referred as frontoethmoidal mucocele by the ophthalmologist. Exophthalmometry revealed 18mm on the right and 22mm on the left side. Slight interference of the left eye mobility to the medial and upper direction, and visual defect on the superolateral area were detected, but no periorbital swelling nor chemosis were found.
Extranasal approach to the frontal and ethmoidal sinuses was made and this procedure revealed encapsulated subperiosteal abscess measured 8mm long in diameter at the border between frontal and ethmoid bone in the medial wall of the orbit. Concomitant inflammation in the frontal and ethmoidal sinuses was proved.
Postoperative course was uneventful.View full abstractDownload PDF (4887K) -

JOURNAL FREE ACCESSA 63-year-old man was admitted to our hospital with a symptom of dysphagia since he had eaten tangle a week before. He couldn't drink even water, so he lost ten kilograms for a week. By roentgenologic examination, we found a hen's egg sized defect like an esophageal tumor. We also performed an esophagofiberscopic examination, and found a foreign body composed of tangle and noodles of devil's-tongue, which looked like an esophageal tumor.
We couldn't extract the foreign body by esophagoscopic techniques because of its softness, then we tried to destroy the foreign body into pieces with a grasping forceps (bascket) which was inserted into the biopsy channel of the esophagofiberscope, then washed them away with water. After the removal the esophagus was examined fluoroscopically and endoscopicallly, but neither functional nor organic stenosis was there.
These foreign bodies are relatively rare in Japan. In the past literature, we found 3 cases of esophageal foreign bodies composed of tangle without stenosis in the esophagus.View full abstractDownload PDF (5883K) -

JOURNAL FREE ACCESSOn the basis of anatomical investigations in some selected mammals and of the report by Negus and other investigations, the author discussed olfaction, respiration and degluatition from a evolutional point of view. These functions were related to anatomy and physiology of the larynx in various spacies. Relation between olfactory function and location of the epiglottis, changes in pattern of deglutition according to the descent of the larynx, and relation between respiration and deglutition are of special interest when one looks at the comprehensive mechanism of olfaction, respiration and deglutition.View full abstractDownload PDF (7538K) -

JOURNAL FREE ACCESSAnatomical structure of the hypopharynx and cervical esophagus of men, dogs, cats, rabbits, cows, horses and pigs was comparatively investigated under an operation microscope. The results are summerized as follows:
1. Four different types of the structure of the cricopharyngeal muscle were observed. This indicates that there are differences in strength and area of pinch-cock activity among the species.
2. The esophagus was attached to the larynx at the midsaggital line of the posterior aspect of the cricoid cartilage with a muscular structure. The muscular structure was rectanglar in horses and rabbits, whereas it was of fan-shape in men, dogs and pigs. No muscular structure was observed in cats.
3. In horses, the muscular structure presented a very unique location, intervening between the arytenoid cartilage and the ring muscle of the esophagus. This may account for the special pattern of deglutition in horse.
4. In men, dogs and cats, the cricopharyngeal muscle seemed less powerful but broader in the area of pinch-cock activity than in cows, horses, pigs and rabbits.
5. In the esophagus of dogs and cats, there was a ring of mucosal bulge at the lower edge of the cricoid cartilage. This seems to suggest that the bulge conpensates for the less powerful action of the pinch-cock.View full abstractDownload PDF (1818K) -

JOURNAL FREE ACCESSStructure of the vocal fold viewed in frontal section was comparatively investigated with larynges of man, dog, cat, rabbit, cow, horse and pig. Observations were made under an operation microscope. The results were as follows:
1. The thyroarytenoid muscle consisted of small muscle bundles. The muscle bundles presented various shapes: triangular, rectangular, or laminar shape.
2. The size of the muscle bundles differed not only between species but also bet-ween different locations. The bundle was big at the lateral and caudal part of the vocal fold, whereas it was small at the medial and cranial part. The former appears to be advantageous for laryngeal closure, and the latter, for phonation. The muscle bundles of the medial part in man were thin and rectangular, indicating a supreme evolution for phonation.
3. The major axis of the cross-section of the muscle bundles was directed horizon-tally, obliquely or vertically. The vertical type, observed in man, appears to be the most adequate to phonation, the horizontal type as observed in cow seems to be the least adequate, and the oblique type as in dog and cat, in between.
4. In man, dog, and cat, the mucosa presented a structure adequate to wavy movement during vibration. The species which did not show such a structure, i. e. cow, horse, pig and rabbit, appears to have poor phonatory function, regardless of the exsistence of separated ventricular and vocal folds.
5. The elastic conus presented a similar tendency as observed in the mucosa.View full abstractDownload PDF (4270K) -

JOURNAL FREE ACCESSFor the purpose of the protection from the noise induced deafness and the disturbance of the blood circulation to hand by noise and vibration for the workers using chain saw, a new type of the chain saw attachment was produced, which was fixed to the tree to cut off and worked by a remote controlled handle.
The intensity of the noise to the ear and the intensity of the vibration to the handle were measured using a sound meter and a special pick up which was attached to the chain saw handle.
Comparing to the ordinary chain saw, the distance between the ear and the source of the noise was reduced only 1.5 meter, so the reduction of the intensity of the noise was only 4 1dB in A specificity, and it overed 95 dB under which noise level was recommended to the health of the workers. So it should be designed to have a much more reduction of the noise.
The intensity of the vibration was reduced remarkably, it valued to any direction under 0.7 G., 117 dB. About the intensity of vibration, it was recommended under 3 G to the health of the workers using the vibrating machine, so this new machine was effective to the reduction of the intensity of the vibraion.View full abstractDownload PDF (782K) -

JOURNAL FREE ACCESSSeventeen cases of malignant tumor of the paranasal sinuses were treated with the intra-arterial infusion of 0.12 95 hydrogen peroxide as a supplementary means of radical operation or radiation therapy during the last two years and four months.
The hydrogen peroxide solution was infused with an infusion pump in about an hour period. This infusion was performed everyday for about 10 days. Changes in the oxygen tension (Po2) of normal tissues and tumor tissues by hydrogen peroxide infusion in these cases were measured with a mass spectrometer (MEDSPECT, MS 8).
The results were summarized as follows:
1. Mean tissue Po2 were not different between normal tissues and tumor tissues
2. On the first hydrogen peroxide infusion, Po2 in the normal and tumor tissues builds up slowly during the arterial infusion and tends to drop off rather sharply when the infusion is stopped. On the 5-8 th hydrogen peroxide infusion, Po2 in theses tissues builds up slowly during the arterial infusion. But, when the infusion is stopped, Po2 tends either to decrease gradually or to increase gradually.
3. Both in the normal tissues and tumor tissues, the tissue Po2 and the increment of the tissue Po2 on the 5-8th hydrogen peroxide infusion tend to fall.View full abstractDownload PDF (2732K) -

JOURNAL FREE ACCESSThe right recurrent laryngeal nerve was excised or crashed one cm under the cricoid cartilage in dogs. Three days, 3 weeks and 3 months after the surgery, the larynx was removed and the thyroarytenoid muscle was examined with an electron microscope.
The arrangement of muscle fibrils was slightly disturbed and the nerve ending was diminished at the neuromuscular junction in specimens 3 days after the surgery. Any other remarkable change was not found. Three weeks after the surgery, the muscle fiber was thin, disordered in its arrangement and sporadically torn up. Both degenerated and little degenerated muscle fibers were observed in the same specimen. The number of mitochondria was reduced and its cristae were diminished. Three months later, the atrophy of muscle fibers was advanced in the excised case and their regeneration was found in the crashed case.View full abstractDownload PDF (17528K) -

JOURNAL FREE ACCESSHair rootlet is the central core of stereocilia (hair) which is found in the sensory cells of the organ of Corti. Hair rootlet goes down from at the basal portion of hair into the cuticular plate. There are two kinds of rootlets, tubular and rod shaped. The diameter of the rootlet is under 100nm.
TEM observation of the rootlets by tannic acid fixation revealed that the hair rootlet consists of 50A diameter microfilaments (protofilaments). Ten to fifty micro filaments lying parallel to one another in each rootlet go down into the cuticular plate. On cross-sectioned specimen of the hair rootlet, these microfilaments form hexagonal pattern. The diameter of the microfilaments accords with that of G-actin (50Å).View full abstractDownload PDF (3619K) -

JOURNAL FREE ACCESSThe present SEM observation was performed for clarifing the evaluation and the influence of 0.25% Empecid (clotrimazole solution) and polyethlene glycol, as using as the otic solution, to the cilia of the middle ear mucoepithelium in normal guinea pig.
On 7th day, after receiving of these solution, cilia of the both group animals showed marked degeneration, which were the disappearance and confusion of cilia, and the appearance of secreted amorphous substances. On 14th day, these degenerated cilia had started to regenerating and had showed the new normal cilia on the final 21st day.
The result of this experiment suggested that the degenerated cilia cells due to 0.25% Empecid might be able to regenerate, with in 2 weeks.View full abstractDownload PDF (14637K) -

JOURNAL FREE ACCESSThe present study was undertaken to investigate Cinnarizine for its effectiveness in the treatment of Ménière's disease. A total of 41 newly admitted or readmitted patients with Meniere's disease were involved in this study. Of these 41, 5 were in the attack stage, 27 were in the quasi-attack stage (less than 1 month after attack) and the remaining 9 were in the silent stage between attacks. In 4 of the first 5 cases the use of Cinnarizine resulted in a prompt disappearance or reduction of vertigo, tinnitus and nystagmus,(adrenocortical hormone not used because of side effect). In 25 of the 27 cases in the quasi-attack stage the use of Cinnarizine brought about suppression of vertigo and tinnitus with a subjective improvement in general condition. Two of the 9 cases in the silent stage between attacks had recurrence of attack under therapy with the drug. On an overall basis symptomatic improvement rate was estimated to be 72% for vertigo, 78% for tinnitus, 50% for nystagmus, 40% for deviation on stepping tests and 33% for hearing impairment. From these results it seems justifiable to assume that Cinnarizine is effective in the relief of symptoms of Meniere's disease during its attack and quasi-attack stage.View full abstractDownload PDF (764K)
