Eight cases of acute onset hearing loss in the contralateral ears of severely hearing-impaired and profoundly deaf subjects were reported. The preceding hearing losses were sudden deafness in 5, mumps in 1, post acoustic neuroma surgery in 1, and unknown in 1. The recent hearing losses were acute low-tone sensory hearing loss in 3, later attack of bilateral non-simultaneous sudden deafness in 4, and accidental incidence of sudden deafness in the hearing ear in 1. Low-tone hearing loss was supposed to be caused by consensual delayed endolymphatic hydrops. Prognosis of the low-tone hearing loss was fairly good with the exception of one case with recurrence one year later. However, outcome for bilateral sudden deafness was poor; only 1 of 4 improved. Hearing of the patient with accidental loss improved.

For effective treatment of recurrent vertigo, it is necessary to examine the patient not only physically but also psychologically and to interview him about his social situation. If generally treatments accepted fail, or if the patient improves during hospitalization without treatment, then he should be suspected of having psychosomatic problems. It may be useful to correlate symptoms with development, family environment or occupational history.
We describe here a patient with bilateral Meniere's disease with fluctuating hearing loss for whom we found interviews to be important.

A 67-year-old man was hospitalized for septic meningitis following acute otitis media in the right ear. Four months after onset of meningitis he consulted our clinic complaining of fluid in the middle ear. Computed tomographic scan showed a large bony defect in the posterior fossa plate of the right temporal bone. Magnetic resonance imaging demonstrated that there was continuity of cerebrospinal fluid (CSF) through the area of bone erosion into the mastoid air cells. An intact canal wall mastoidectomy was performed to repair the bony and dural defect with obliteration of adipose tissue into the mastoid cavity. CSF otorrhea has not recurred for 1 year after surgery.
This is the fourth case of adult-onset spontaneous CSF otorrhea in Japan.
The causes of CSF otorrhea related to dural defect and bone erosion are discussed.

The incidence and prognosis of recurrent Bell's palsy were examined in a total of 418 patients with Bell's palsy. Bell's palsy was recurrent in 6.5%, 3.1% unilateral, and 1.7% bilateral alternating. The age at the first attack in patients with three or more recurrent palsies was significantly younger than that in those with non-recurrent palsy or with two attacks. The patients with two or more attacks had a worse prognosis than did those with no recurrence or a first recurrence. The stapedial reflex was of prognostic value in patients with both non-recurrent and recurrent palsies. However, the ENoG and NET examinations were not useful in the prediction of the prognosis of recurrent facial palsy.

At our clinic, we encountered 272 cases of facial bone fracture between 1983 and 1993. These patients were analyzed by age, gender, cause and location of the fracture.
There were 202 nasal bone fractures, which comprised 59.3% of all facial bone fractures. Males were significantly predominant (75.2%). These injuries mainly occurred during sports, fighting and automobile accidents.
While usually single and rather slight bone fractures such as nasal bone fractures occured during sports, more severe fractures involving many facial bones occured in high speed, such as automobile accidents. Moreover, orbital bone fractures mainly resulted from fightings or sports. Precise otolaryngological knowledge and management is indispensable for ENT clinicians.

A 70-year-old man was found to have an immature teratoma in his paranasal sinuses. A biopsy showed components of all three germ-cell layers: neural, epithelial, and glandular elements. MRI revealed a large irregular tumor invading the anterior cranial base. Intra and extracranial approaches were used for total resection. The bony defect of the anterior cranial base was reconstructed with a pericranial flap and temporal muscle flap. The patient was treated with chemotherapy and radiation following surgery. However several pulmonary metastases and effusion appeared, and he died 8 months after the operation.

A 20-year-old female complained of left visual disturbance and eyeball pain, CT scan and MRI revealed a tumor of which the main lesion was in the sphenoid sinus, the histopathological diagnosis was embryonal type rhabdomyosarcoma.
External beam irradiation with 50Gy and simultaneous chemotherapy with vincristine failed to eliminate the tumor in the sphenoid sinus. Remote afterloading system radiotherapy (RALS) was administered through the sphenoid sinus, which was opened surgically. The residual tumor had vanished by the end of RALS therapy.
This method is an effective means of controlling residual tumor in paranasal sinuses.

We describe the six patients with “lymphoepithelial cyst (branchial cyst) of the parotid gland” treated during the past ten years in our hospital and review the others reported to date in Japan. The majority of the patients were in the middle age group and there was no definite sex difference. The cyst was more often in the upper part of the parotid gland than in the lower part and more often in the superficial lobe than in the deep lobe. The treatment of this lesion requires radical measures, such as complete enucleation or lobectomy of the parotid gland. The definitive diagnosis depends on the histopathological findings.

Primary malignant lymphomas of the parotid gland are very rare. These neoplasms are believed to be associated with autoimmune disorders, such as Sjögren's syndrome. We present a case of primary malignant lymphoma in a patient with rheumatoid arthritis.
A 69-year-old woman was referred because of right parotid gland enlargement. CT scans showed a right parotid tumor. We planned a superficial parotidectomy. However, the tumor gradually shrank and became impalpable in a month. Three months later, the patient was aware of right parotid gland enlargement again. CT scans showed another right parotid tumor. Examination of tissue obtained by fine-needle aspiration raised great suspicion of malignant lymphoma. A parotidectomy was performed. Histologic examination showed diffuse non-Hodgkin's lymphoma, mixed cell type. Postoperatively, the patient received radiotherapy and chemotherapy. One year after the operation, the patient is alive with no evidence of recurrence. The literature on primary malignant lymphoma of the parotid gland is reviewed.

Seven patients were treated for parapharyngeal space masses. Six had benign tumors (neurilemoma in 3, pleomorphic adenoma in 1, extracranial meningioma in 1, and abscess in 1) and one had a malignant tumor (metastatic thyroid carcinoma). Meningioma and thyroid carcinoma are very rare in the parapharyngeal space. Surgical resection was performed in all seven patients. Four of them were operated on through a cervical-transpharyngeal approach with osteotomy. The meningioma involved X and XII cranial nerves and was adherent to C1 and C2 vertebrae; it was thought to have originated from one of the two cranial nerves involved or from the C2 nerve. The thyroid carcinoma in the parapharyngeal space was a retopharyngeal lymph node metastasis from a papillary thyroid carcinoma which had been treated eight years earlier. Preoperative radiologic evaluations, which included CT, MRI and angiography, were very useful in the selection of the surgical approach.

A 31-year-old male with obstructive sleep apnea syndrome was treated with KTP/532 laser midline glossectomy. He had complained of severe snoring and hypersomnolence for 2 years and sleep apnea for 1 year. His apnea index (Al) was 65.0 events/h and the lowest arterial O
2 saturation (SaO
2) was 44%. Cephalometric analysis and flexible fiberoptic pharyngeal endoscopy during Müller's maneuver indicated that the space-occupying sites responsible for sleep apnea were at two different levels (oropharynx-soft palate and hypopharynx-base of the tongue). The application of KTP/532 laser to midline glossectomy with uvulopalatopharyngoplasty caused slight bleeding but no obvious complications. Postoperative respiratory parameters were greatly improved: Al 5.5 and lowest SaO
2 85%. Cephalometric and fiberoptic findings showed an enlarged pharyngeal space at the level of the base of the tongue. Sleep-related complaints disappeared completely.

The authors report a very rare case of pleomorphic adenoma in the epiglottis. A 46-year-old man complained of “unclear voice”. Initially he was diagnosed with an epiglottic cyst after laryngoscopy, lateral X-P, and CT. We performed a puncture of the tumor through a laryngoscope, and determined that this disease was not a cyst, but a tumor. Biopsy and tracheotomy was performed. Pathological diagnosis of the tumor was Pleomorphic adenoma. After 10 days, tumor resection was performed by pharyngotomia mediana suprahyoidea under general anesthesia.
For the diagnosis of pleomorphic adenoma in the larynx, biopsy is essential. It might be necessary to perform the biopsy several times because pathological diagnosis of pleomorphic adenoma in the larynx is not easy.
To treat pleomorphic adenoma of the larynx, surgical resection is primarily recommended. Determination of the method of the surgical approach depends on the tumor size. When the tumor is smaller than 2cm, surgery with a laryngoscope is recommended. However for larger tumors, a skin incision should be made.

From May 1991 to December 1993, 667 patients underwent surgery under general anesthesia in our department, and 37 of them received blood transfusions during 13 different surgical procedures. Radical resection with reconstruction for oropharyngeal carcinoma caused the largest amount of blood loss. The Hb value was less than 10g/dl in 59%, and the Ht was lower than 27% in 38%. The blood loss was greater than 30% of the total circulating blood volume as predicted from the height and weight of 48% of the 37 patients. In the total group of 667 patients, blood loss of more than 600ml (criteria for transfusion) occurred in 33 patients; six of them did not receive blood transfusion. We introduced the concept of MSBOS (Maximum Surgical Blood Order Schedule) and found from the data of the present study, of the values of MSBOS in several surgical procedures that blood loss of more than 600ml occurs in 80% of the patients. We estimate that the amount needed for replacement is eight units for oropharyngeal cancer (radical resection with reconstrution) and six units for cancer of the tongue (radical resection with reconstrution).

To determine the role of temporal information in speech perception, we created synthesized sound with temporal information alone and without such information as formant. To create such a sound, we plot the zero-crossing point in the original sound wave and place clicks on each point. So this sound consists of clicks. This stimulus sound contains only the timing information of stimulation and no significant information on the formant on the sonagram. Various types of this stimulus sound were created from the original sounds of Japanese vowels, VCV syllables, sentences with meaning and without meaning, song with background music and jazz instrumental music. We performed hearing experiments using this sound in twelve normal volunteers. The results showed that the perception of simple sounds (vowel, VCV syllable) were near the chance level. The perception of meaningless Japanese sentences were poor. Japanese sentences with meaning were well perceived. The perception of instrumental music was quite poor. These results suggested that the temporal information plays an important role in speech perception.

The “so-called shoulder syndrome” occurs frequently after neck dissection. However, some patients whose accessory nerves were sacrificed during operation have normal shoulder mobility. There is some controversy about whether the cervical nerves to the accessory nerve innervate the trapezius muscle.
Using a neurostimulator, we examined the motor innervation of the cervical contributions during operation. After neck dissection, we examined the function of the trapezius muscle with manual muscle testing (MMT) and electromyography (EMG) and correlated the results with whether or not the accessory nerve had been preserved.
In eight of 42 sides (19%) motor fibers from the cervical nerves reached the trapezius muscle. Scapular elevation was not greatly restricted even if the accessory nerve had been sacrificed, presumably because of the compensatory function of the levator scapulae muscle. Motor action potentials of the inferior fibers of four trapezius muscles were present even after the accessory nerve on that side had been sacrificed. It appears, therefore, that the inferior fibers of the trapezius muscle can be innervated by nerves other than the accessory nerve.

We studied the clinical effects of low dose long-term administration of clarithromycin (CAM) for chronic sinusitis. Twenty-nine patients were treated with 200mg of CAM per day for at least 12 weeks.
1) The overall improvement rate of subjective symptoms and rhinoscopic objective findings were estimated at 55.2% 12 weeks later.
2) The clinical effects depended on the duration of administration up to 3 months. Longer administration exceeding 12 weeks may further improve the better clinical effects.
3) Side effects were observed in 2 patients (6.9%), but they were not significant.

The efficacy of ondansetron, an antagonist of serotonin 5HT
3-receptor, was compared with that of metoclopramide, an antagonist of dopamin D
2-receptors, in the contorol of nausea and vomiting induced by cisplatin treatment in 30 patients with head and neck cancers. Nausea and vomiting were significantly in those treated with ondansetron less than in those receiving metoclopramide. It was concluded that ondansetron is an effective agent for the control of cisplatin-induced nausea and vomiting. The urinary excretion of 5-hydroxyindoleacetic acid (5-HIAA), the main metabolite of serotonin, was significantly increased in the patients who received cisplatin chemotherapy. There was a significant positive correlation between the degree of nausea induced by cisplatin and the urinary excretion of 5-HIAA, suggesting that the release of serotonin induced by cisplatin causes emesis.
