JOURNAL FREE ACCESSThe utility of single fiber EMG (SFEMG) of the orbicularis oris muscle in facial nerve paralysis was studied in 10 normal human subjects and 12 patients with facial nerve paralysis. In addition, the jitter values of SFEMG were obtained in an animal model, and then the results of the studies were compared. The statistical rejection ellipses of humans and a cat model showed very similar patterns, and the more severe the facial damage, the greater the deviation from the rejection ellipse range. Furthermore, as the recovery proceeded, the coordinates of the jitter values gradually approached each other and finally came into the normal range. The jitter values of SFEMG and stimulated SFEMG in an animal model showed similar patterns during the recovery phase of facial nerve paralysis. We thus conclude that follow-up study of the jitter values of SFEMG and stimulated SFEMG in patients with facial nerve paralysis can offer valuable information that is useful and relevant to their treatment.View full abstractDownload PDF (22721K) -

JOURNAL FREE ACCESSThe correlation between the neurophysiological values of facial nerve paralysis through electroneurography (ENoG) and the pathohistological findings of nerve damage was evaluated using a recently developed animal model for facial paralysis. Every week for four weeks after the onset of paralysis, the pathological levels of nerve damage in the buccal branch were compared with the ENoG values to evaluate the utility of ENoG. A histological study of the horizontal portion of the facial nerve as a primary ischemic lesion in an animal model was also performed. As a result, ENoG reflected the degree of the nerve damage in advance of the pathological changes during the initial week, and then accurately reflected the rate of nerve degeneration in the severe nerve damage two weeks after the onset. The main change one week after the onset of paralysis was edema among the nerve fibers. After the second week, a marked decrease in the number of nerve fibers was noted and macrophages started to absorb the products of degeneration. After the fourth week, and active regenerating process was observed. This study thus showed that a follow-up study using ENoG in patients with facial nerve paralysis can therefore provide valuable information that is both useful and relevant to their treatment.View full abstractDownload PDF (26773K) -

JOURNAL FREE ACCESSThe effects of rotation stimulation and caloric stimulation on the neuronal activity in the posterior hypothalamus (PH) were studied in anesthetized guinea pigs. The spontaneous discharge of PH neurons demonstrated a change in 63%, and the main change was inhibition. It started gradually after the rotation began and then lasted for several minutes even after the rotational cycle. Caloric stimulation produced a neuronal activity change in almost 60% of the tested PH neurons. The PH neurons which were excited by hot stimulation were excited by cold stimulation, and the PH neurons which were inhibited by hot stimulation were inhibited by cold stimulation. the above response pattern therefore closely correlated with the regulatory mechanism of the vestibulo-autonomic reflex.View full abstractDownload PDF (15693K) -

JOURNAL FREE ACCESSLipoma is a benign mesenchymal tumor that is often found on the back-chest wall, the upper leg and in the cervical region. However, parotid lipoma is a vary rare tumor. The incidence of parotid lipomas among all parotid gland tumors is only approximately 1%. Of the 112 parotid gland tumors previously treated in our department, the parotid lipoma reported herein is our first. The patient was a 57-year-old female who was admitted to our hospital complaining of an elastic tumor in the left parotid region. The tumor was excised under general anesthesia. The histopathological diagnosis indicated a mature lipoma and the postoperative course was good.View full abstractDownload PDF (12271K) -

JOURNAL FREE ACCESSA solitary metastasis of renal cell carcinoma to the thyroid gland is very rare. However, we recently experienced such a case. A-56-year-old female presented complaining of an anterior neck mass. An ultrasonogram and CT scan revealed tumors of the bilateral lobe of the thyroid gland and a concentration of 201TI was observed in the tumors. Fine needle aspiration cytology was performed, and a benign lesion was suspected. The right lobe and isthmus of the thyroid were resected. A frozen study revealed a clear cell carcinoma and suggested it to be metastasis of renal cell carcinoma. Since no other metastasis was revealed by further examinations, a complete thyroidectomy was then performed. Metastasis from renal cell carcinoma was thereafter confirmed by both immunohistology and electron microscopy.View full abstractDownload PDF (9788K) -

JOURNAL FREE ACCESSWoodman's operation is a representative operation that can improve dyspnea which is cause by bilateral recurrent laryngeal nerve paralysis. It is very important to measure the width of the glottis during this operation, because it influences both the respiration and voice functions. In order to measure the exact width of the glottis, we designed a method for applying a fragment of silicone mesh. This method is very easy to perform and is also an objective one, so it is expected to be used more frequently in the future for laryngomicrosurgery.View full abstractDownload PDF (6005K) -

JOURNAL FREE ACCESSFifteen cases of head and neck tumors derived from adipose tissue in our department from 1982 to 1993 were reviewed and analyzed clinically. They included ten males and 5 females. Pathologically, they were classified into 4 types as follows: lipoma (10 cases), lipomatosis (3 cases), lipofibroma (1 case) and liposarcoma (1 case). In the lipoma cases, 2 cases were under 3cm in diameter, while 7 cases were from 3 to 10cm and 1 case was over 10cm. The preoperative diagnosis for lipoma can be made by a CT scan. Lipoma is characterized by a low-dense and homogeneous region. The histological appearance of lipomatosis differed from that of lipoma although both CT scan examinations showed similar findings. All benign tumors were surgically extirpated, while the case of liposarcoma was treated by a combination of operation, radio and chemotherapy.View full abstractDownload PDF (9277K) -

JOURNAL FREE ACCESSA case of Glomus tympanicum tumor is herein reported. The patient was a 69-year-old female who complained of a left hearing loss and pulsatile tinnitus. The otoscopic examination revealed a reddish and pulsatile tumor in the tympanic cavity. The tumor seemed to be located within the tympanic cavity based on the CT and angiographic findings. A radical mastoidectomy and radiation therapy were performed. The absence of any tumor recurrence was confirmed 17 months after her discharge. We also reviewed the 19 cases of Glomus tympanicum tumors previously reported in Japan and determined that pulsatile tinnitus is an important symptom for making an early diagnosis.View full abstractDownload PDF (15404K) -

JOURNAL FREE ACCESSFrom 1986 through 1991, 41 patients with hypopharyngeal carcinoma were treated at the Department of Otorhinolaryngology, University of the Ryukyus, Faculty of Medicine. The treatment modalities included surgery in 20 patients, and surgery plus postoperative radiation in 21 patients. Nineteen patients (47%) had recurrent tumors, which were the most frequent in the neck lymph nodes. The frequency of recurrence seemed to be correlated with the presence of N factor before treatment. The recurrence rate observed after treatment was 35% in the operated cases and 57% in the post operatively irradiated cases. Based on a comparison of the treatment modalities, surgery plus post operative radiation was found to offer a slight advantage over surgery alone in reducing tumor recurrence.View full abstractDownload PDF (7894K) -

JOURNAL FREE ACCESSA histopathological examination was performed on serial specimens of the carotid artery that were resected from patients with cervical squamous cell carcinoma. No perivascular or perineural extension of the cancer cells was observed even in the cancer invaded arterial wall. Intraluminal extension, however, was more likely demonstrated in patients in which both a neck dissection and irradiation were performed. It was thus considered that either a surgical approach or irradiation may reduce histological resistance against cancer cell invasion to the carotid artery. The safety margin for a cervical artery resection was 10mm from the macroscopic edge of the invading tumor. Local recurrence appeared in the skin of the neck in one case, however, no distant metastases was observed in any of the patients whose cervical artery was resected.View full abstractDownload PDF (12711K) -

JOURNAL FREE ACCESSConcering the pathological mechanism of sudden deafness, various etiologies have been discussed. Sudden deafness may be a kind of syndrome which contains various pathological conditions. Many therapeutic methods have been proposed and their validities have been statistically examined by numerous researchers. According to these studies many cases of sudden deafness were managed as a disease with the same pathological conditions. In this paper I pointed out the pitfalls in the evaluations of the various therapeutic methods examined in the manner mentioned above. In addition, a statistical analysis may also be meaningless in evaluating such therapeutics.View full abstractDownload PDF (5180K) -

JOURNAL FREE ACCESSTwenty-two ears of residual cholesteatomas, which were found in 81 cases undergoing revised surgery, were analyzed.
1. The residues were found in 20% of the PF (Pars flaccida) type cholesteatomas, while they were found in 53% of the PSQ (posterior-superior quadrant) type.
2. In 67% of the total residues, the 2-dimensional size of the residues were less than 1 quarter of the tympanic membrane.
3. In the PSQ type, the residues were most frequently found in the stapes foot plate area.
4. The residues of the child cases were larger than those observed in the adult cases.
5. The wet cases tended to result in the presence of a large residue.View full abstractDownload PDF (6995K) -

JOURNAL FREE ACCESSThe purpose of this report is to utilize the standing test as a screening test for an impairment of the labyrinthine function. One hundred and seventy-one patients with unilateral canal paresis (CP) and 293 normal subjects were examined by the one-leg standing test with their eyes closed. Each subject was tested to see whether or not he could stand on one leg with his eyes closed for more than 10 seconds. The results were judged as being “possible” or “impossible”, respectively. The results were evaluated regarding age and the degree of CP. In 97 patients with either severe CP or complete CP, 5 of 21 patients whose ages ranged from 20 to 40 years ware judged to be “possible”, but all 76 patients over 40 years of age were judged as being “impossible”. In 74 patients with moderate CP, all age groups, except for those in their 70's, had a frequency of “possible” patients ranging from 6 to 50%. Almost all of the normal subjects whose ages ranged from 20 to 40 years were judged to be “possible”. From these results, we can thus rule out severe and complete CP in “possible” patients aged over 40.However, we could not rule out moderate CP in a “possible” patient regardless of the patient's age. Either CP or other vestibular system disorder is strongly suggested in “impossible” patients whose ages range from 20 to 40.View full abstractDownload PDF (7061K) -

JOURNAL FREE ACCESSForty-nine ears of 30 children diagnosed as a having psychogenic hearing loss were studied retrospectively. All the patients were under 16 years of age when they visited the Kyushu University Hospital. The follow-up periods ranged from 6 to 92 months after being diagnosed. We only explained to both the patients and to their parents that the disease itself was not organic, but spontaneously curative and that they would likely heal as they grow older without under going any treatment. The rate of improvement in hearing loss on the audiogram was found to be 86%. An interesting finding was that the rate of improvement in the patients who had graduated from junior high school was better (96%) than that in the patients who were still in junior high school (79%). These observations suggest that a psychogenic hearing loss in children is thus considered recover naturally without any treatment as they grow up.View full abstractDownload PDF (7001K) -

JOURNAL FREE ACCESSIn order to clarify the relationship between dry mouth and Candida, we investigated the early morning saliva of patients who complained of experiencing dry mouth. It was revealed that the positive rate of Candida was 71% in the patients with dry mouth, while on the other hand, it was only 56% in the normal cases. The positive rate and density of Candida in the patients who showed a low level both in the gum test and in the salivary total flow volume at rest were apparently different from those of normal cases. But the positive rate and density of Candida in the cases that showed a normal level in both tests were not significantly different from those of normal cases. We gave Florid gel, which is an antifungus drugs, for two weeks to the patients whose density of Candida was more than on plus, and thereafter the Candida either disappeared or decreased in all cases while its effective rate was 80%. The subjective symptoms improved in 93% of patients, and among them “the improvement or disappearance of the feeling of dry mouth” was recognized in 23% of the patients. Candida was mostly found in the saliva of patients whose function of the salivary glands had apparently decreased, therefore we concluded that the existance of Candida might at least be an indirect cause of the feeling of dry mouth.View full abstractDownload PDF (9677K) -

JOURNAL FREE ACCESSA clinical study was conducted on the effect of Tosufloxacin, a new oral pyridone-carboxylic acid antibiotic agent, in 92 cases of otorhinolaryngological infections diseases. The conclusions of this study are summarized as noted below: 1) The overall efficacy rate was 79%, while the efficacy rate was 88% in acute infections, and 71% in chronic infections.
2) The efficacy rate of each infectious disease was as follows; Pharyngolaryngitis 100%, tonsillitis 95%, otitis media 63%, paranasal sinusitis 73%.
3) The efficacy rate of gram positive organism infections was 88%, while that for gram negative organism infections was 100%.
4) Mild diarrhea was observed as a side effect in only 1 case.
The above results therefore suggest that Tosufloxacin is a useful drug for the treatment of otorhinolaryngological infections.View full abstractDownload PDF (7333K) -

JOURNAL FREE ACCESSThe effects of the combined use of drugs on smell disturbance due to chronic sinusitis were studied in 15 patients. Roxithromycin (RXM) was orally administered as the main drug at a dosage of 300mg in two divided doses, while Azelastine hydrochloride (AH) was orally administered as the concomitant drug in a daily dosage of 2 mg in two divided doses. The administration period was eight weeks. In the group administered RXM alone (7 patients), smell disturbance was observed to improve in 71% of the cases, while it improved in 67% in the group given both RXM and AH (8 patients); the difference was not statistically significant. In one case from the RXM+AH administration group, however, the efficacy was excellent, which indicated a potential advantage of the combined drug use. It is still necessary to more carefully evaluate this approach employing both a lager number of patients as well as developing a more objective method for its assessment.View full abstractDownload PDF (5336K) -

JOURNAL FREE ACCESSThe efficacy and safety of Ofloxacin (OFLX) in acute otitis media and acute exacerbation of chronic supprative otitis media were compared between the use of oral medicine and otic solution. The patients were divided into two groups. One received 0.3% otic solution of OFLX twice a day for 7 days (n=28). The other orally received 600mg of OFLX three times a day for 7 days (n=25). The clinical efficacy of the otic solution and the oral OFLX medicine were 82% and 72%, respectively; and the difference was not significant (P=0.69). The bacteriological elimination rate was 79% in those treated with the otic solution and 81% in those treated with oral medicine; the difference was not significant (P=0.50). No side effect was observed in any patients (0%) treated with otic solution and side effect in only one patient (0.04%) treated with the oral medicine who showed some stomach discomfort. These findings suggested that the 0.3% otic solution of OFLX was as useful as the oral medication in treating both otitis media and an acute exacerbation of chronic supprative otitis media and is thus recommended instead of oral medication, especially in children and patients with severe general condintion.View full abstractDownload PDF (13834K)
