JOURNAL FREE ACCESSThe maximum slow phase velocity of caloric induced nystagmus could be measured with the herein described newly developed method, which needs no calibration, using an infrared CCD camera, a video tape recorder (VTR) and a TV monitor. Fourteen patients suffering from dizziness underwent caloric tests (5ml of 20° water). Their eye movements were recorded simultaneously in the VTR and an electronystagmogram (ENG) with their eyes open in darkness. The maximum velocity of the slow phase was measured using this method, and was less than 10°/s in 7 ears of 6 patients who were all diagnosed as having canal paresis (CP). Concerning CP, the evaluation of the caloric tests recorded with the VTR correlated with the ENG findings. Since we can evaluate the caloric tests quantitatively in most patients more easily with the VTR than with an ENG, this newly developed method is therefore recommended especially for busy ENT doctors.View full abstractDownload PDF (10115K) -

JOURNAL FREE ACCESSNasal polyps sometimes hide the true anatomy of the middle nasal meatus. We first perform a polypectomy using the MicroDebrider system whenever a patient presents with polyps in the middle nasal meatus. The main reason for using this system is to accurately recognize the anatomy of the middle nasal meatus and to also safely perform endoscopic endonasal sinus surgery. The MicroDebrider system depends on suction to pull tissue into the cutter window, stabilize it for resection by an oscillating blade, and then remove it from the operative field. Bleeding in the operative field is easily controlled because both suction and resection can be done simultaneously. We consider the above described method to be both safe and effective for endonasal surgery in patients with nasal polyps.View full abstractDownload PDF (8329K) -

JOURNAL FREE ACCESSA case of an inverted tooth eruption into the nasal cavity is herein reported. The patient was a 53-year-old female who had complained of recurrent nasal bleeding for several years. There was no history of nasal trauma or operation. In the right nasal cavity, a small bony mass was found. A CT scan showed a bony-dense mass attached to the right nasal septum. We removed the bony mass under local anesthesia. Histological examinations showed the extracted specimen to contain dentin. All the patients teeth were still intact and the projection was thus thought to be a supernumerary tooth. Since 1976, 54 cases of inverted tooth eruptions into the nasal cavity have been reported. A review of the literature revealed the ages of patients with erupted teeth ranged from 2 to 67 years, while the male to fermale ratio ranged from 1.25 (30 cases) to 1 (24 cases). Most erupted teeth were considered to be supernumerary ones.View full abstractDownload PDF (11329K) -

JOURNAL FREE ACCESSOsseous benign tumors of the tongue are very rare. During the past two years we have experienced 4 cases of osteoma which originated at the base of the tongue. Most of them were located close to the foramen caecum. Our findings suggest that the etiology of osteoma of the tongue might thus be closely related to the foramen caecum and thyroid gland.View full abstractDownload PDF (11003K) -

JOURNAL FREE ACCESSWe experienced a case presenting with a traumatic cervical abscess. When the patient was admitted, the edematous swelling of the epiglottis and pharynx were observed, but no abscess was apparent on the CT scan. The patient was treated with antibiotics and steroids at first. The local symptoms and laboratory data temporarily improved, however, they thereafter again worsened. Another CT scan revealed the existence of an abscess which was thus incised and drained. After operation the clinical course was good. We thus concluded that a surgical approach is necessary in cases where conservative therapy dose not prove to be effective. In addition, a CT scan was also found to be useful in making an accurate diagnosis in such cases.View full abstractDownload PDF (8737K) -

JOURNAL FREE ACCESSPleomorphic adenoma in the submandibular gland comprises about 10% of all patients with pleomorphic adenomas, and is known to be rare. Six cases of pleomorphic adenoma in the submandibular gland who were treated at our department, were thus clinically analyzed in this paper. These cases (3 males and 3 females) ranged in age from 25 to 69 years of age with an average of 53.7 years. The chief complaint of all cases was tumor palpation. The average period of time from onset until operation was 64 months. The tumors of all cases were surgically removed while preserving the facial nerve and all were thereafter followed by histopathological examinations. No cases of pleomorphic adenoma were diagnosed to have carcinoma and there were also no cases of recurrence. We thus concluded that a complete removal of the tumor with the normal gland at the first operation and a long-term follow-up are necessary for the effective treatment of pleomorphic adenoma in fhe submandibular gland.View full abstractDownload PDF (12444K) -

JOURNAL FREE ACCESSWe experienced the case of a large epiglottic cyst in whom tracheal intubation proved to be difficult to carry out by ordinary oral intubation. We herein report our newly developed device to keep the airway open in such cases and also make a review of the literature. The patient was a 35-year-old man who could be intubated transnasally by the use of a fiber-optic bronchoscope that was intserted through the anesthetic tube. This was done in a sitting position and awakened state to avoid any airway obstruction, and it was thus found to be both safe and effective. Moreover, we could easily remove the cyst by needle aspiration which also made it easier to confirm its stalk. A histopathological examination revealed an epidermoid cyst which was lined by a stratified squamous epithelium accompanied by some lymphoid tissue.View full abstractDownload PDF (8385K) -

JOURNAL FREE ACCESSMaking a diagnosis of a foreign body in the lower airway is generally performed based on a detailed case history, conventional radiographic examinations and the physical findings of the patient. In most doubtful cases, however, it is not easy to confirm a foreign body especially if it is a radiolucent subject. We made a diagnosis using magnetic resonance imaging (MRI) in two cases suspected of having an inhalated peanut in the lower airway. This method was thus found to be very useful in removing a foreign body located in the bronchus.View full abstractDownload PDF (10829K) -

JOURNAL FREE ACCESSThirty-nine patients with oropharyngeal cancer who were operated on at the Department of Otorhinolaryngology at the University of Ryukyu from 1988 through 1994 are herein reviewed. The overall five-year survival rate was 48%. The five-year survival rate by stage was 78% for stages I and II, while it was 39% for stage III+IV. The major cause of death in our cases was distant metastasis. The therapeutic regimen including chemotherapy against distant metastasis may thus result in an improvment in the survival rate for advanced cases.View full abstractDownload PDF (7114K) -

JOURNAL FREE ACCESSBetween January 1989 and December 1993, 89 head and neck cancer patients, who were all older than 70 years of age, were treated and surgery was performed on 39 patients. The primary sites included laryngeal cancer (10 cases) and thyroid cancer (14 cases). The cumulative five year survival rate was 44.1% in the 39 surgically treated patients. In contrast, the cumulative five year survival rate of the patients without operation was 29.6%. Regarding the quality of life of these patients, it is important to obtain the close cooperation of both the family and medical staff in postoperative rehabilitation.View full abstractDownload PDF (7846K) -

JOURNAL FREE ACCESSThe possiblilty has been reported that the orbicularis oris muscle is controled by both contralateral and ipsilateral facial nerves. We therefore investigated the clinical significance of this phenomenon based on the function of evoked electromyograpy (EGM). After normal side facial nerve stimulation, with an increase in the facial nerve denaturation, the amplitude of the ipsilateral evoked electromyography of the orbicularis oris muscle increased and the incubation period was also prolonged.View full abstractDownload PDF (4769K) -

JOURNAL FREE ACCESSTo clarify the arrangements of muscular bundles, the precise localization and share based on the cell size of motorneurons innervating each muscular bundle in the feline intrinsic laryngeal muscle, a morphological study was performed along with surgical, microscopical, histological and immunohistochemical analysis.
In the intrinsic laryngeal muscular bundles, the cricothyroid (CT), posterior cricoarytenoid (PCA), thyroarytenoid (TA) and interarytenoid (IA) muscles were divided into two groups; the vertical and oblique parts in CT and PCA, vocalis and lateral part in TA, and the paired and unpaired bundles in IA. There was a small piece of cartilage in the rostra half of IA.
Regarding the localization of the motorneurons supplying these laryngeal muscular bundles, differentiation of the rostrocaudal extent of each cell column could not be determined, while that of the distribution in the transverse plane showed an interesting pattern. The motoneurons supplying the vertical parts related to respiration and phonation were located more medially compared to those related to swallowing in the CT and TA.
The laryngeal motorneurons were divided based on the soma size. In the CT motoneurons, the small cell (-25μm) group comprised more than 60% of all cells. Other motorneurons were evenly distributed into small cell and medium cell (26-50μm) groups. These results suggested that each laryngeal motorneuron playing a role in the laryngeal functions has its own special feature.View full abstractDownload PDF (27870K) -

JOURNAL FREE ACCESSWe administered beraprost sodium, an oral drug of a stable analog of prostaglandin I2 (PGI2), to 34 cases with sudden sensorineural hearing loss. The results were then compared with 31 patients who did not receive PGI2 therapy. We evaluated the outcome using the recovery rate and improved hearing criteria of the Ministry of Health and Welfare in Japan. No statistically significant difference was observed in the outcome between the patients treated with PGI2 and those not treated with PGI2. Five patients showed an elevated anticardiolipin antibody level in the serum. The complete cure rate was slightly higher than nomal in these 5 patients. We experienced a patient who showed an improvement in hearing disturbance by the adiministration of oral PGI2 alone and another patient whose hearing was dependent on the dose of PGI2.View full abstractDownload PDF (16721K) -

JOURNAL FREE ACCESSThe clinical efficacy of an oral anti-allergic drug, pemirolast potassium (Alegysal®), was evaluated in 97 patients with perennial allergic rhinitis by assessing the efficacy mainly for nasal congestion based on the nasal findings and the nasal air flow. The final global improvement rating was either “markedly improved” or “moderately improved” in 44.7% of the patients in week 4 of treatment and in 64.7% of the patients in or after week 5 of treatment. The overall safety rating was “adverse reactions occurred but the treatment was continued” in 3 patients. The utility rating was “very useful” or “moderately useful” in 48.9% of the patients in week 4 of treatment and 66.7% in or after week 5 of treatment. The nasal air peak flow value was determined using a simple air flow meter improved significantly after treatment, while that determined by the anterior (ANT) method only showed a slight tendency to improve after treatment. These findings thus suggested that Pemirolast potassium is useful for the treatment of perennial nasal allergy and especially improves the symptoms of nasal congestion by reducing the nasal air flow resistance.View full abstractDownload PDF (24028K)
