ジャーナル フリーSound localization in the horizontal plane primarily depends on the interaural time difference (ITD) and interaural intensity difference (IID). When sounds with identical ITD or IID are presented to both ears, the sound image is lateralized to the side receiving the earlier or louder stimulus within the head. Currently, ITD and IID discrimination abilities are separately measured with a commercially available self recording apparatus.
In this review, the history and basic science of sound localization is discussed in detail. Moreover, for future clinical application, sound lateralization abilities of patients with peripheral hearing loss, brain stem disorders, and auditory cortex disorders are described pertaining to discrimination of ITD or IID separately using a self recording sound lateralization system.抄録全体を表示PDF形式でダウンロード (9611K) -

ジャーナル フリーThe primary goal of this study was to verify the incidence and degree of hearing deterioration of JBSNDUE with a prospective long-term clinical follow-up.
Of 173 JBSNDUE cases, 54 were followed up untill their ages reached 25-39 (average 30.7) years. In 23 cases (42.6%) hearing deterioration was confirmed. In 16 cases, discrimination scores for nonsense syllables were as low as 0%.
The criteria of the “deterioration” of pure tones were irreversible average hearing level greater than 15dB at three adjoining frequencies between 0.25 and 4kHz.
Except 25 of 173 cases, either binaural or monaural amplification was used. However, the incidence of hearing deterioration showed no significant difference between aided and unaided ears.
The clinical features of JBSNDUE were summerized.
The communication ability of those with deteriorated hearing was discussed.抄録全体を表示PDF形式でダウンロード (946K) -

ジャーナル フリーWe describe a case of aortitis presenting sudden deafness with vertigo in both ears. The time of onset was different, with multiple intracranial aneurysms occurring concurrently. The aneurysm was multiple, occurring in the basilar artery and internal carotid arteries. Left side sudden deafness was complicated with a left cerebellar infarction. Therefore an embolism in the anteroinferior cerebellar arteries, caused by a detachment of the parietal thrombus in the basilar aneurysm, may be accountable for sudden deafness. Generally, fluctuating hearing loss occurring in the acute stage of aortitis is due to disturbed blood flow into the inner ear with inflammatory changes in the labyrinthine artery. However, sudden deafness could occur as a partial symptom of cerebrovascular disturbances arising from the blood flow lesion within the skull in the chronic stage of aortitis, as in this case.抄録全体を表示PDF形式でダウンロード (6626K) -

ジャーナル フリーBenign paroxysmal positional vertigo (BPPV) of lateral semicircular canal variant is characterized by geotropic nystagmus when the head is turned from the supine to either lateral position.
The modified Lempert method, one of the canalith repositioning methods, had been reported to be effective for BPPV of lateral canal type. After this method was performed, however, a patient presented ageotropic nystagmus when the head was turned from the supine to either lateral position. This change in the direction of nystagmus seemed to indicate the conversion of canalolithiasis to cupulolithiasis. A canalith was thought to have moved from the proper canal of the lateral canal to the utricle, and moreover, into the cupula from the orifice of the ampulla of the lateral canal. Since this event, we have adopted the head tilt and rotation method. Its effect is as quick as that of the modified Lempert method, and no unfavorable side effects seen in modified Lempert method were observed.抄録全体を表示PDF形式でダウンロード (736K) -

ジャーナル フリーTwo cases of high jugular bulb with attic cholesteatoma are reported. In one case, a pulsating vein was seen through the right tympanic membrane, and in the other, a exposed right jugular bulb was demonstrated by computerized tomography scan.
Both patients had a right acellular mastoid and an enlarged and anterior-lying sigmoid sinus. It was thought that hypoplasia of pneumatization was affected by the anatomical variation in the sinus. Also, judging from the clinical courses of the cases, it seems that the attic wall defects resulted from hypoplasia of the attic, and cholestesteatomas were formed when skin desquamation accumulated in a deep portion of the attic cavity.抄録全体を表示PDF形式でダウンロード (7267K) -

ジャーナル フリーCholesteatomas rarely develop postoperatively as a complication of ear surgery for noncholesteatomatous disease, although the disease is not infrequently seen to recur following surgery for cholesteatomatous middle ear. It has been reported that lateralization of the tympanic graft and postoperative stenosis of the external auditory canal favor the formation of cholesteatomas.
This paper presents a case of an external auditory canal cholesteatoma that developed postoperatively in the ear following tympanoplasty without mastoidectomy. A 56-year-old man, who had undergone bilateral tympanoplasty elsewhere 13 years previously for persistent otorrhea and hearing loss, presented in 1998 with episodic hearing loss and ear discharge in his right ear. Examination of the ear showed a crust located in the posterosuperior part of the auditory canal. A CT scan revealed a round soft tissue density in the external canal, of which the posterior osseous part appeared to be eroded. The lesion was compatible with cholesteatoma in the external auditory canal. The patient underwent an excision of the cholesteatoma and canaloplasty. The patient has been free of his disease for six months postoperatively.
It is suggested that a canal skin incision permits development of an inclusion cyst, giving rise to the formation of cholesteatoma in the external auditory canal.抄録全体を表示PDF形式でダウンロード (4604K) -

ジャーナル フリーJuvenile nasopharyngeal angiofibroma is a benign tumor with rich blood flow, usually observed in young males. Though it should be excised surgically, the operation requires a broad operation field to achieve less blood loss, and a functionally and cosmetically sound method. Here, we report an extensively relapsing juvenile nasopharyngeal angiofibroma, excised with midfacial degloving and Le Fort I osteotomy.
A 16-year-old boy was admitted to our hospital with a right side relapsing juvenile nasopharyngeal angiofibroma. The tumor extended to the infratemporal fossa, sphenopalatine fossa, paranasal sinus and the nasopharynx. Preoperative embolization of the feeding artery could not be performed because his right external carotid artery was ligated in a previous operation 1 year earlier. We performed a midfacial degloving and a Le Fort I osteotomy. The tumor was completely excised. Blood loss was 2250g, and no scar was noted on his face.抄録全体を表示PDF形式でダウンロード (8241K) -

ジャーナル フリーOrbital osteoma is an uncommon tumor. We report a case of orbital osteoma originating from the ethmoidal bone in a 59-year-old female. She was referred to our hospital in 1992 because of progressive exophthalmos. A CT scan showed a high density mass at the ethmoidal bone extending into the right orbit. It was diagnosed as an orbital osteoma. 6 years later she experienced diplopia. Therefore, we decided to excise the tumor. The removed solid tumor measured 15×20×30mm, and the histological diagnosis was a compact type of osteoma. After surgery, all ophthalmic symptoms disappeared.抄録全体を表示PDF形式でダウンロード (5831K) -

ジャーナル フリーFifty parotid tumors were resected surgically during the past five years between 1994 and 1998 in the Department of Otolaryngology, Tachikawa Hospital. There were 27 males and 23 females. The peak incidence was in the fifth decade of life and the average age was 49 years. 41 tumors were benign and 9 were malignant. A pleomorphic adenoma was noted in 50% of the parotid tumors, followed by Warthin's tumor (22%).
Facial nerve palsy occurred in 36% of the patients after operation. Most of the facial nerve palsies after operation recovered in 3 months. Mandibular branch palsy was noted most often.抄録全体を表示PDF形式でダウンロード (585K) -

ジャーナル フリーBasal cell adenocarcinoma, a new type of malignant tumor, was added to the classification of a salivary gland tumor by WHO in 1991. Most cases develop in major salivary glands, especially parotid glands.
We report here a case of basal cell adenocarcinoma which developed in the submandibular gland of a 52 year-old man. A pathological diagnosis was based upon Haematoxylin-Eosin staining and immunohistochemistry. The specimen was obtained from total resection of the submandibular gland and upper neck dissection. The patient has survived for 3 years after operation without any signs of local recurrence of regional or distant lymph node metastasis.
Clitical points at pathological diagnosis were also discussed.抄録全体を表示PDF形式でダウンロード (7035K) -

ジャーナル フリーThis study was designed to estimate the swallowing function after surgery in lingual and oropharyngeal cancer patients. We evaluated the process of swallowing by pharyngoesophagography using a digital radiography system and measuring pharyngeal transit time. In addition, some questions were asked about swallowing conditions to patients.
Four patients following hemiglossectomy had good swallowing function. In oropharyngeal cancer patients, especially those who have a transection at the base of the tongue, the pharyngeal transit time is prolonged, meaning a worse swallowing function in the pharyngeal stage.
A digital radiography system was useful in observing pharyngeal stage and measuring pharyngeal transit time.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The following six parameters were studied in 119 patients who responded to a questionnairebased long-term survey of 208 adults who had undergone surgery for obstructive sleep apnea syndrome in the previous 8 years: 1) snoring, 2) sleep apnea, 3) daytime sleepiness, 4) nocturnal arousal, 5) malaise, and 6) quality of sleep.
The patients were divided into a markedly or moderately improved group (group A) and a slightly improved or unchanged group (group B) based on improvement of the apnea-hypopnea index (AHI) after surgery.
In group A, improvement of snoring, sleep apnea, daytime sleepiness, and quality of sleep tended to decrease over the long term.
In group B, improvement of these four symptoms was more marked than improvement of the AHI in the early postoperative period (1 year after surgery), with a significant difference between the two. The same pattern was also apparent in the long-term results.
There was no major difference between the improvement of nocturnal awakening or malaise and improvement of the AHI over either the short or long term in groups A or B.抄録全体を表示PDF形式でダウンロード (1088K) -

ジャーナル フリーA 49-year-old male was treated for chronic tonsillitis with brachytherapy 40 years ago. The inflammation of the tonsils was improved by the treatment. On August 18th, 1998, he consulted our hospital complaining of sudden throat pain. The pain deviated to the left, intensified with eating and continued for several hours every day for one month. An X-ray revealed a metallic foreign body in his left tonsil. A left tonsillectomy was done on January 14th, 1999, and the foreign body was removed completely. It was a small gold tablet, 3×1×1mm in size. A scintillation counter proved that the metallic foreign body was a radon (220Rn) seed. This is a rare case of a radon seed buried in the left tonsil of a patient for 40 years.抄録全体を表示PDF形式でダウンロード (2070K) -

ジャーナル フリーThe patient was a 48-year-old woman with a retropharyngeal abscess. She had a sore throat after digesting a fish. No fishbone was detected at the first hospital she visited, therefore, she was treated with antibiotics and steroids until one was observed by CT scan. Eight days later, she was referred to our hospital. The fishbone was removed orally from the posterior pharyngeal wall under a general anesthesia. Three days after the operation, she had a fever and a non-productive cough. CT scan revealed a retropharyngeal abscess and drainage was performed. The abscess subsided and she was discharged 10 days later.抄録全体を表示PDF形式でダウンロード (4900K) -

ジャーナル フリーAn aneurysm of the extracranial internal carotid artery is a rare disease. We report of a patient with this disease who complained of dysphagia and dyspnea, requiring tracheostomy. The patient was a 78-year-old female, who had a left pharyngeal large mass. The patient presented with right hemiplegia and motor aphasia due to a brain infarction, and left recurrent laryngeal nerve paralysis and Homer's symptom caused by a large mass that had recently appeared. After therapeutic embolization of the internal carotid artery, we performed aneurysmal resection without arterial reconstruction.抄録全体を表示PDF形式でダウンロード (5308K) -
