ジャーナル フリーA stastistical study of 41 cases with denture foreign bodies in the air and upper food passages which were treated in our department during the past 21 years was done.
(1) Males were more frequently affected. The ratio of male to female was about 2 to 1.
(2) Of 41 dentures, 2, 2 and 37 were lodged in the air passages, hypopharynx and esophagus respectively.
(3) There were 5 complete mandibular dentures in 41 cases.
(4) The causes of the denture foreign bodies were originated to the problem of denture itself in 29 cases, that of the patient himself in 2 cases and both in 10 cases.
(5) Of 39 problematic dentures, 16 showed the breakage such as plate fracture and clasp deformity, but the other 23 showed no breakage. In this latter group, poor holding of the denture was ascribed to miss-making or miss-planning.
(6) Of 12 patients with problems in their physical function, 5 had suffered from cerebrovascular disease and 3 from geriatric dementia.
(7) The denture foreign body in aged patients with physical hypofunction tends to increase in recent years.
(8) Of 39 dentures tried to remove by esophagoscopy, 18 were done with difficulty and they were detatchable partial dentures with one artificial tooth and 2-arm-clasps lodged at the first and/or second isthmus of the esophagus. Though we have a denture removed successfully at the third trial, we have no case needed external esophagotomy.
(9) Duplicated denture models were made in 20 cases prior to the procedure, and we certify that these models play an important role for the safer removal of denture foreign bodies.抄録全体を表示PDF形式でダウンロード (1300K) -

ジャーナル フリーThe effect of direct antigen (KLH) challenge of endolymphatic sac (e. sac) on caloric response was investigated in guinea pigs. The caloric response was not significantly suppressed both in the primary KLH challenged ears and in the PBS challenged ears as compared to the unchallenged contralateral ears.
In the animal of secondary KLH challenge of the e. sac, the caloric response was significantly reduced in the challenged ears as compared to the unchallenged contralateral ears and to the PBS challenged ears. These result suggested that local immune reaction mounted in the e. sac caused immune injury not only to the e. sac but also to the vestibular function.抄録全体を表示PDF形式でダウンロード (413K) -

ジャーナル フリーAs a conservative treatment for Bell's palsy, the high dose steroid therapy introduced by Stennert in 1982 are highly evaluated clinically from many investigators. In the present study, model animals with experimentally-induced facial paralysis were prepared using guinea pigs in which the effect of administration of high dose steroid on the recovery process of the palsy was investigated electrophysiologicaly and morphorogicaly.
The main trunk of the facial nerve was exposed under Nembutal anesthesia, and compressed for 10 sec. using a needle holder. The model animals were divided into three groups, a high dose steroid group (Group A) and a low dose steroid group (Group B) and control group (Group C).
The evoked EMGs of orbicularis oris muscle were recorded before operation and on the third, seventh and 14th days after operation, and each time course of the amplitude changes in Groups A, B and C was compaired. Recovery patterns of amplitude in Group A was much more rapid than in Groups B and C.
Light microscopy revealed extensive destruction and existence of only a small number of normal myelinated fibers on the 14th day after operation in Group C. In Group A, however, these changes were slight. And the numbers of normal myelinated fibers decreased to a minimum in Group C, while the numbers of fibers in Group A already increased on the 14th day. Electron microscopy, in Group C, disclosed distortion of the sheath of myelinated fibers and abnormal changes in the axon. But in Group A, dense lamellar structure of myeline sheath and no axonal degeneration were disclosed.
These experimental results support the efficacy of high dose steroid therapy upon Bell's palsy.抄録全体を表示PDF形式でダウンロード (5734K) -

ジャーナル フリーA retrospective study of 44 patients who were involved in combination with chronic sinusitis and bronchiectais provided better understanding of the etiology in the relaltionship between upper air ways tract and lower air way tract.
The incidence of bronchictasis was found in 5%, 3 out of 60 cases with chronic sinusitis and that of chronic sinusitis in 45%, 44 out of 98 cases with idiopathic bronchiectasis. Both side involvements of the paranasal sinus and the lung were statically high in sinobronchiectasis compared to chronic sinusitis or bronchiectasis involved alone. The past history of the patients with sinobronchiectasis showed high occurence of bronchial asthma or allergic rhinitis, habitual angina of the throat, acute otitis media and pneumonia. A chest X. Ray evaluation of 70 patients with chronic sinusitis alone revealed relatively high incidence of abnormal fibro-nodular shadow in the lung compared to 70 patients without chronic sinusitis.
It was thought that weakness of air-way tract to infection in the patients with sinobronchiectasis might play some role on break down of sino-bronchial syndrome, a combination disease of chronic sinusits and chronic bronchitis.抄録全体を表示PDF形式でダウンロード (683K) -

ジャーナル フリーThe cloudiness of the maxillary sinus in Waters-view is 37% in paients with nasal allergy. The pathogenesis of this cloudiness has not fully understood yet ; is it due to the type-I allergic reaction, or secondary maxillary sinusitis? To clarify the pathology, we studied the infiltrated cells in 37 mucosae of the maxillary sinus in which X-ray revealed an abnormal shadow. Samples were also taken from 9 antrums with chronic sinusitis, and 18 and 4 nasal mucosae form the inferior turbinate with nasal allergy and sinusitis, respectively. Each specimen were fixed with Carnoy solution and formalin, and were stained with Hematoxylin & Eosin, and with Alcianblue & Safranin. Numbers of formalin sensitive and resistant mast cells and eosinophils were determined in the epithelium, and superficial and deep layers of the lamina propria, respectively. The population of both mast cells in each compartment was not different between nasal allergy and maxillary sinusitis both in the nasal and maxillary mucosae. The number of eosinophils in the maxillary and nasal epithelia significantly increased in nasal allergy compared with sinusitis. These results suggested that type-I allergic reaction might occur in the maxillary mucosa as well as nasal mucosa in patients with nasal allergy.抄録全体を表示PDF形式でダウンロード (1365K) -

ジャーナル フリーRecords of 77 patients who had surgically proven perilymphatic fistula (PLF) from 1979 through 1988 were reviewed. During this period, 16 patients had a fluctuating hearing loss in association with spells of vertigo. Ten of these patients had been diagnosed as having Meniere's disease by at least one otolaryngologist before exploration for PLF. Audio-vestibular functions were compared between these PLF patients and those with classic Meniere's disease. The following factors are associated with a high incidence of PLF : (1) Low frequencies hearing loss which has father deterioration within few days ; (2) A rapidly fluctuating low frequencies hearing loss with wide variability ; (3) Very long duration of positional nystagmus ; (4) Absence of canal paresis. PLFs often mimicked Menier's disease, although these patients did not have classic Meniere's symptoms. This study emphasizes this overlap.抄録全体を表示PDF形式でダウンロード (354K) -

ジャーナル フリーRhinocerebral mucormycosis is a rare and fatal deep fungus infection occurring in debilitated patients. Its reports have been recently increased because of the increase of such conditions as uncontrolled diabetics, leukemia, and cancer. A 60-year-old male suffering from continuous headache and fever was diagnosed as meningitis, and repeated culture of cerebrospinal fluid was negative. Antibiotic therapy was ineffective. CT scan revealed brain abscess in the right frontal lobe and bone defect over the right posterior ethmoidal sinuses. Both maxillary and ethmoidal sinuses were operated on 38 years ago. The patient was suspected to have rhiologic brain abscess. We intended to remove the source of infection in the right posterior ethmoidal sinuses beneath the base of the skull and to repair the defect of dura mater. The operation was tried on the 6th hospital day. There was a cyst in the posterior ethmoidal sinuses and an intact denuded dura mater over the cyst. The causative organism was not detected by smear test, bacteriological and fungal culture. He relapsed into lethargy, and died on the 21th hospital day due to the vast cerebral infarction. Autopsy revealed rhinocerebral mucormycosis. The literature on this disease was also reviewed and discussed.抄録全体を表示PDF形式でダウンロード (2344K) -

ジャーナル フリーSclerosis of auditory ossicle was experimentally induced by fixation of the stapes, and its effect on the tympanic membrane vibration was examined using fresh 10 canine temporal bones by means of holographic interferometry. By changing the sound pressure (from 90 to 110dB) and the frequency (from 250Hz to 8kHz) in steps, vibration of the membrane was induced in a free field. At each frequency, the vibration of the membrane was photographed by the time averaged method using He-Ne laser. A small hole was created in the tympanic bulla and the stapes was fixed with an adhesive (Alon Alpha®), followed by closure of the hole.
Before stapes fixation, the posterior part of the membrane showed a simple vibration pattern, forming cocentric interference circles at frequencies from 250Hz to 2kHz. At 3kHz, segmental vibration began to be noted, and complex segmental vibration was seen at frequencies 4, 5 and 6kHz. The vibration after stapes fixation became simpler at frequencies over 3kHz, accompanied by decrease in the number of segmental vibrations. Vibration amplitude in the posterior part of the membrane decreased from 250Hz to 3kHz, while it increased at frequencies over 4kHz. In the anterior part of the membrane, the amplitude decreased at frequencies under 2kHz, remained unchanged at 3kHz and increased at frequencies over 4kHz after stapes fixation. In the tip of the manubrium mallei, the amplitude decreased at frequencies under 3kHz and increased at frequencies over 4kHz. Thus, a shift of peak vibration to high sound region was observed after stapes fixation at every part of tympanic membrane.
In brief, fixation of the stapes elevated the amplitude of tympanic membrane vibration at high frequencies and reduced it at low frequencies. This appeared to be caused chiefly by an elevation in the stiffness of the middle ear vibration system.抄録全体を表示PDF形式でダウンロード (2232K) -

ジャーナル フリーAuricular hematoma is not rare condition and its prognosis has been considered to be good in Japanese textbooks. Recurrence of the hematoma, however, frequently occurs by use of simple aspiration or incision, and a pressure dressing. In this paper, we report a case of ruptured othematoma and review the biliographies concerning the pathology and treatment of othematomas.
A 37-year-old man sustained a fist blow to his left ear at the beggining of May, 1989. He was first seen with auricular hematoma on July 4, but refused a surgical treatment. The laceration of the skin overlying the hematoma occurred by once more fist blow on July 26, with the upper auricle divided into anterior and posterior parts. The auricular cartilage was broken into several pieces, some of which attached to the anterior side and the others to the posterios side.
Under general anesthesia, fibrin glue was applied to the dead space after irrigation, minimal debridement, and removal of the clots. Four horizontal mattress sutures were put through the entire pinna after the anterior skin was protected by fluffed gauze with antibiotic ointment and the posterior skin by buttons. The dressing was allowed to remain in place ten days and was then removed. Nine months after the operation the pinna appeared almost normal.
In recent reports, the othematoma is considered to occur between the perichondrium and the cartilage, or within the cartilage. Various techniques have been applied to treat the othematoma, which are classified into three types : incision and drainage, pressure dressing with splinting mold, or with mattress suture. Treatment of choice is discussed, with reviewing the advantages and disadvantages of each method.抄録全体を表示PDF形式でダウンロード (2615K) -

ジャーナル フリーPrimary tissue culture system from the middle ear and the tracheal epithelium of the guinea pig was established using collagen gel method. The cultured epithelium was studied by phase-contrast microscopy, light and scanning electron microscopy. The outgrowthal area of the epithelium was quantitatively measured for period of up to ten days. In the middle ear cavity, the mucosal explants were sampled from various sites in order to compare their differentiational and proliferative activities.
The mucosal explants attached on collagen substrates were composed of ciliated, non-ciliated, goblet and basal cells. This basic structure was similar to the natural middle ear epithelium. The ciliated cells showed well organized cilia. Most of the outgrowthal cells devoid of fibroblastic cells in the monolayer were polygonal shaped with numerous microvilli. The morphology of the outgrowthal cells changed from columnar or cuboidal to squamous shapes in the area away from the explants. There was a correlation between the distribution of the ciliated cells in the outgrowths and these in the explants.
The explants with columnar or cuboidal ciliated epithelia sampled from the opening of the eustachian tube or its neighborhood formed more than eightfold outgrowthal sheets in vitro. This is comparable to tracheal epithelia. On the other hand, the explants with simple squamous epithelia sampled from the area distal to the eustachian tube showed about fourfold proliferative activity.
We concluded that this culture system would be useful for the study of cellular multiplication and differentiation mechanisms of the respiratory tract epithelium.抄録全体を表示PDF形式でダウンロード (2765K) -

ジャーナル フリーA 44-year-old female with adenoma of the middle ear was reported. Her chief complaint was hearing loss in the right ear. A white mass inside the right external auditory canal was observed. Audiometry revealed a combined deafness with the average hearing of 38. 3 dB for the speech frequencies. The study by high resolution X-ray CT revealed a density area as like as a soft mass in the tympanic cavity.
A tumor existing mainly in the hypotympanum was surgically removed and modified type III tympanoplasty by interposing the malleus head as an autograft as a columella was done. Postoperative course was good and the average hearing improved slightly to 30 dB. Histopathological study with stains of HE, PAS, mucicarmin, colloid iron, NSE and S-100 protein showed adenoma of the middle ear.抄録全体を表示PDF形式でダウンロード (1853K) -
