    From several studies of experimental motion sickness, I have concluded that the discomfort of motion sickness warns the brain of spatial disorientation, otherwise, the impairment of spatial orientation produces dangerous equilibrium ataxia. The possibility that spatial orientation plays an important role in the adjustment of daily actions, and that the locomotor system and the gaze control system may be equally under the control of the cognition-motor transforming system is discussed. In support of this hypothesis, locomotion disorders evoked by walking while wearing horizontally reversing goggles and the nystagmus induced by Coriolis' stimulation are discussed. Primitive motor programs of action may be immediately and uniformly adjusted by the kaleidoscopic changes of spatial orientation through the activity of the vestibular and cerebellar complex.

    Cytomegalovirus (CMV) in the most frequent cause of congenital infections in humans. The neurodevelopmental outcome of infected neonates is well documented and includes a significant risk of sensorineural hearing loss (SNHL).
    We studied five SNHL subjects with congenital CMV infection. All 5 infected subjects were found to have bilateral progressive SNHL and the deterionation to profound occurred during the first two years of life.
    Transient evoked otoacoustic emissions (TEOAEs) were recorded in 2 subjects and the TEOAEs of all 4 ears were abnormal. These effects confirmed that hearing loss associated with congenital CMV infection was due to cochlear dysfunction at least, as literature on the histopathology had indicated.
    One of the five subjects was asymptomatic. The etiology of hearing loss in children often is not identified and we concluded that SNHL in some children was caused by congenital CMV infection.
    Because the majority of infants with congenital CMV infection are asymptomatic at birth, routine screening of all newborns for congenital CMV infection should be carried out and the management of infected children should include periodic assessments. As the therapy for congenital CMV infection is not effective, CMV vaccination for women of child bearing age should be considered. In the future, vaccination will significantly reduce the prevalence of hearing loss in children.

    A 29-year-old male had complained of bilateral hearing loss and bilateral tinnitus since five years ago. He was diagnosed with otosclerosis, and a stapedotomy was performed in the right ear two years ago at another hospital. Following surgery, he complained of oscillopsia during loud sounds. His eye movements were subsequently recorded, during loud sound stimulation. With left ear stimulus nystagmus was not detected, but with right ear stimulus, pendular nystagmus in the vertical plane was seen with sounds of 500Hz 100dBHL. An exploratory tympanotomy was subsequently performed. Except for findings associated with poststapedotomy, there was no evidence of abnormalities, including leakage of perilymph. We thought that the piston wire might be stimulating the labyrinth membrane, so the wire was removed, together with the footplate. The oval window was closed with a vein graft and allograft stapes were inserted in the inverted position. Tullio's phenomenon with downbeat and torsional nystagmus was seen during one month after surgery.
    Although the origin of vertical eye movement is unclear, observations suggest that Tullio's phenomenon in this case was caused by hyperexcitability of the otolith organs.

    A 44-year-old female with a facial nerve neurinoma extending to the middle cranial fossa is described. The symptoms of the patient included tinnitus and hearing loss on the affected side, with no history of facial palsy. The pathological diagnosis was made following a biopsy of the tumor obtained from behind the tympanic membrane under exploratory tympanotomy.
    A middle cranial fossa approach and middle ear surgery were required to remove the tumor, and facial nerve decompression was performed after removal of the tumor. Intraoperative findings revealed that the tumor, which originated from the vertical to the pyramidal portions of the facial nerve, occupied the aditus and the posterior half of the epitympanum and the mesotympanum. Destruction of the tegmen of the epitympanum was evident, and the tumor was adherent to the dura of the middle cranial fossa.
    The tumor was removed intracapsularly with preservation of the facial nerve, continuity of the nerve fiber was confirmed using nerve stimulator. Facial palsy which was severe on the left side after the surgery, but gradually improved to become partial paralysis until now. Subsequent CT scans and MRI have revealed no signs of recurrence, and symptoms of recurrence of the tumor are also absent at present.

    A supernumerary tooth in the nasal cavity was first reported in Japan by Kanasugi in 1901. Since then, approximately 130 cases have been reported in Japan. A white foreign body was found in the right nasal cavity of a 5-year-old boy at an otorhinolaryngological clinic. On radiological examination, we found a tooth that had a dentinoenamel layer. It was diagnosed an impacted supernumerary tooth. Under general anesthesia the impacted supernumerary tooth, which appeared to be a canine tooth was extracted.

    Olfactory neuroblastoma is a rare malignant tumor of neural crest origin, arising in the nasal cavity. We encountered three cases of olfactory neuroblastoma : Case 1, in which the tumor had invaded to the ethmoidal sinus, Case 2, in which the tumor was limited to the nasal cavity, and Case 3, in which the tumor had invaded the anterior cranial fossa.
    All 3 patients were treated with a combination of surgery, radiotherapy, and chemotherapy. All of the patients are still alive without any evidence of recurrence.

    A 65-year-old male with maxillary sinus mycosis accompanied by rhinolithiasis was reported. The subject complained of bilateral nasal obstruction and hyposmia and was referred to us because of a mass lesion seen in the bilateral nasal cavities. The mass was stony hard and movable when pushed by a suction tube. A computed tomographic scan revealed that the X-ray density of the mass was equivalent to the bone and that the right maxillary sinus had an abnormal mass with both high and low density areas. In addition, the posterior and lateral walls of the right sinus were found to be thicker than those of the left side. The nasal mass was removed endonasally followed by an endonasal ethmoidectomy under endoscopical control. The mass was found to be a calcified stone. The right maxillary sinus contained muddy green pus without any fungus ball or calcified mass. No bacteria or fungi grew from the pus taken from the maxillary sinus. Histological examination of the stone revealed a bolus of fungal threads in which no septa were identified. Thus, the patient was diagnosed with maxillary sinus mucormycosis accompanied by rhinolithiasis. The postoperative period has been uneventful.

    Surgical treatments for postoperative maxillary cysts include the peroral method (trans-maxillary sinus method) in which the cyst wall is totally removed or conserved, and opened to the nasal cavity by incising from the gingiva, and the endonasal method in which the cyst wall is opened to the nasal cavity by the nasal approach. Recently, the endonasal method is more widely used because CT and endoscopy can be applied. Forty-two patients (56 sides) who underwent surgery for postoperative maxillary cysts in Nanyo City Hospital over the last four years were reviewed. Preoperative CT findings, surgical methods, operative findings and prognosis were analyzed. Forty-one sides were monocystic and 15 sides were multicystic. Forty-two sides were of the medial type, 4 sides were of the lateral type and 10 sides were of the mixed type. Twenty sides (35.7%), which were both monocystic and medial, were operated on by the endonasal method, while the transmaxillay sinus method was used for the remaining sicks. Though one of endonasal patients experienced a relapse of the maxillary cyst, the endonasal method was associated with less suffering and a shorter operative time than the trans-maxillary sinus method. Therefore, the endonasal method is recommended, if the postoperative maxillary cyst is both monocystic and medial.

    The case of a 67-year-old male with a bilateral maxillary carcinoma is reported. In 1976, the patient had an operation and irradiation therapy for a right maxillary carcinoma at another hospital, and was tumor-free for 19 years. In 1995, he developed a squamous cell carcinoma of the opposite side, the left maxillary sinus (T3N1M0, stage III). He received combination therapy consisted of intra-maxillary resection of the tumor, radiotherapy to the left maxillary field without the neck field, and chemotherapy with 5-fluorouracil (5-FU) administered from the left superficial temporal artery. Before the chemotherapy, a chemosensitivity test (ATP assay) was carried out. The results showed that 5-FU was the only effective drug. The left cervical metastatic lymph node has completely disappeared following therapy with 5-FU only for over one year. Therefore, this was a true-positive case. In our department, 15 patients have been treated according to the results of the ATP assay, and the clinical predictive accuracy is 87% thus far.

    We report two cases of unresectable pleomorphic adenoma of the parotid gland. The first patient was a 34-year-old female on whom enucleation of the parotid tumor was performed in 1981. The tumor recurred 4 years later and extirpation of the tumor and superficial lobectomy were performed. However, the tumor recurred again in 1991 and we decided during the operation that the tumor could not be resected without sacrificing the facial nerve. The second patient was a 39-yearold female complaining of a tumor of the right parotid gland in 1992. Although we tried to resect the parotid tumor, it was impossible to carry out the operation and preserve the facial nerve. In 1995, we removed the tumor and sacrificed the facial nerve. In both cases, the tumor was located in a deep lobe of the parotid gland and developed in the direction of the superficial lobe, so that the facial nerve was sandwiched in a valley of the tumor. We recognized again that enucleation was contraindicated for pleomorphic adenoma.

    We report 3 cases of Kimura's disease. All patients were male and ranged in age from 15 to 62 years. All cases showed eosinophilic granuloma in the salivary glands and regional lymphadenopathy. Case 1 was initially diagnosed with a malignant tumor by imaging findings (MRI, CT). This patient was treated with steroids only, showing a remarkable improvement. Case 2 with relapsing nephrotic syndrome has been kept free of granuloma by surgery and steroid hormone therapy. Case 3, who underwent surgical excision, experienced recurrence in spite of the continuous application of NSAID (nonsteroid anti- inflammatory drugs).

    Lipomas are benign non-epithelial tumors composed of mature adipose cells. They are rarely encountered in the clinical setting of otolaryngology, although the neck is one of the most predominant locations of lipomas. Two cases of lipoma arising in the neck are reported with a literature review. Case 1: A 20-year-old female had a lobulated lipoma (85×40×25mm) arising in the right submandibular region and parapharyngeal space extending to the skull base. Case 2: A 56-year-old male had a lobulated lipoma (100×65×20mm) arising in the anterior neck extending to the left supraclavicular fossa. CT and MRI were useful for the diagnosis of lipomas. Lipomas in the deep neck show slow growth in the medial direction with a lobulated appearance separating the connective tissue. Therefore, upon first examination, they are often huge extended lesions with less functional disorders. Most cases are considered based on cosmetic issues rather than medical problems. Since complete resection of these tumors necessitates a complicated surgical procedure, early radiological diagnosis and adequate planning for surgery are essential for the treatment of lipomas in the deep neck.

    Multicentric Castleman's disease is characterized by a peculiar multicentric form of lymph node hyperplasia. This report describes a 53-year-old female patient with multicentric Castleman's disease admitted because of generalized lymphadenopathy, including palatine tonsils and adenoids. A CT scan showed well-enhanced masses in cervical, chest and abdomen. Although malignant lymphoma was suspected, based on clinical features, malignant histological findings were not observed in the tonsils. However, the cervical lymphnode showed angiofollicular hyperplasia of the hyaline-vascular type, and the patient was diagnosed with Castleman's disease. A bilateral tonsilectomy and adenoidectomy were perf omed under general anesthesia to relieve the patient's symptoms of nasal stiffness and dyspnea. After surgery, oral prednisolon (60mg) administrated was perfomed daily for 3 weeks, after which the dosage was gradually decreased. After daily oral administration of prednisolon, the multicentric lymphadenopathy almost completely disappeared. Clinical examination showed an increased level of IL-6 in the patient's serum before tonsillectomy and IL-6 positive cells were detected by immunohistological staining of the tonsils. These findings indicate that IL-6 is associated with this disease. The prognosis with this disease is poor, and frequently the patients die rapidly of septicemia or other infections. Since this disorder in some patients is complicated by malignancies, special attention should be paid in observing the course of this disease.

    The management of adenomatous goiter (AG), a disease for which there are various treatment strategies, continues to generate significant controversy. A number of papers have recommended surgical management as a result of the relatively high incidence of combined malignancy reported in patients with this disorder. However, we are reluctant to perform thyroidectomy as the first therapy for this hyperplastic thyroid disease. The overall incidence of thyroidectomy with a postoperative histology indicating as AG, was 8.7% (91 patients) out of 1048 patients being operated on for various thyroid diseases in our department over the last 16 years (1981-1996). However, the number of patients with a correct preoperative diagnosis of AG was 41(3.9%). These 41 patients were categorized as having essential indications for surgical management of AG. Furthermore, the incidence of combined malignancy in the 91 patients who underwent thyroidectomy was as low as 3% (3 patients, all T1N0). On the contrary, the incidence of AG in patients operated on for various thyroid malignancies was 9%. This rate was lower than those reported previuosly, which suggests that efforts directed at a more punctual preopeartive diagnosis, were reasonable. Hence, our first strategy is to treat patients suffering from AG with TSH suppression therapy and repeated ultrasonic echography (with or without fine needle aspiration cytology). This strategy appears to be a reasonable approach in cases of AG.

    The need for drainage to prevent complications after thyroid surgery has been questioned by many authors since the late 1980s. However, little is known about the quantity of discharge after thyroid surgery.
    We measured the amount of discharge drained continuously after hemithyroidectomy with or without contra-lateral tumor enucleation in 90 consecutive patients (10 males and 80 females, mean age 56 years, ranging in age from 24-79 years) with benign (78 cases) and malignant (12 cases) thyroid tumors. The amount of drainage was not huge and ranged from 8 to 132ml with a mean of 51ml during the 4 days after surgery. The average amount was significantly larger in the patient group drained with a stronger suction system (J-VAC), when compared to that in the group with a weaker suction system (MANOVAC).
    Where immediate action based on close observation of patients is available under life-threatening conditions, such as massive bleeding or airway obstruction, prophylactic routine drainage is not necessary after uncomplicated thyroid surgery.

    The efficacy of EN028 was evaluated in 25 patients (20 males, 5 females) who had been diagnosed with simple snoring by the sleep test. All patients did not wish to undergo surgical treatment and gave their consent to participate in the present clinical study after having been given full and adequate information about the purpose and investigational nature of the study.
    The efficacy rate was 68%, and two patients dropped out in the middle of the study because of alleged post-drug discomfort. Non-responds for the most part were found to have severe hypoventilation or a low post-drug decrease in nasal airway resistance. If such patients could be avoided in the selection of study subjects, the efficacy rate of EN028 would be higher than in the present study.
