    We reviewed the histopathologic changes of the temporal bone associated with cochlear implants, based on our own clinical experience and the results of animal and human temporal bone studies conducted to date.
    Cochlear implants in animals, especially in guinea pigs were associated with a high degree of trauma and the subsequent foreign body reaction caused largely by the insertion of the electrodes caused unavoidable trauma in the vicinity of the round window and damage to the spiral ligament was especially common. The basilar membrane was also occasionally damaged. Such damage may lead to degeneration and hearing loss by secondary invasion of the spiral ganglion, and should therefore be avoided at all costs.
    In the majority of deaf patients the hair cells of the organ of Corti have already disappeared. The afferent nerve components, consisting primarily of the remaining spiral ganglion cells, therefore play an important role. Fortunately, these components were more resistant to the trauma and foreign body reaction than anticipated.

    Meningoencephalocele is a rare disease. Its incidence is regarded as one out of 35000 to 40000 birth. We accidentally discovered meningoencephalocele in a 4-month-old male who came to our hospital for treatment of dyspnea. This patient had suffered from retraction breathing and cyanosis from about ten days after his birth. The cyanosis disappeared with time but the dyspnea and retraction breathing persisted.
    His laryngopharynx and nasal cavity were examined with a fiberscope at our outpatient clinic. We decided to perform choanal plasty because we speculated that the dyspnea was caused by choanal stenosis.
    Before choanal plasty we performed CT-scan of his head. The CT-scan revealed the presence of a Basicranial meningoencephalocele. Choanal plasty was abandoned as a treatment option, and tracheostomy was performed to improve the dyspnea. Had choanal plasty been performed, cephalomeningitis, may have resulted. Previous reports have suggested that polypoid masses in the nasal cavity may represent meningoencephaloceles which have cleared up. Accordingly, close attention to this possibility is required prior to surgical invasion of the nasal cavity.

    Meningeal carcinomatosis is caused by diffuse metastasis from solid malignant tumors to the leptomeninges. In this article we report a case of meningeal carcinomatosis, which initially presented as unilateral sudden profound hearing loss and was finally diagnosed by cerebrospinal fluid cytology.
    A 42-year-old woman with a history of breast cancer was seen at our hospital complaining of dizziness and tinnitus in her left ear. Six days later, she suffered left sudden hearing loss, and left facial palsy was seen two weeks later. No tumor was evident on either magnetic resonance imaging or computed tomography. One month later, diplopia and severe headache appeared and she was diagnosed with meningeal carcinomatosis by cerebrospinal fluid cytology.
    Consideration of the possibility of meningeal carcinomatosis is necessary when diagnosing sudden profound hearing loss in a patient with a history of the malignant tumor.

    A simple yet reliable easy screening method for functional hearing loss was developed using an air conduction pure-tone audiometer.
    We performed pure-tone audiometry in 440 ears from 220 patients (101 males, 119 females) using 7 continuous and 7 pulse pure tones at 125 Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz and 8000 Hz. The hearing thresholds measured by continuous tones were compared with those measured by pulse tones at each frequency, and the number of frequencies which showed a 10 dB or greater threshold improvement or deterioration were counted.
    Of the 440 ears, 130 ears were diagnosed with sensorineural hearing loss of unknown origin, 51 ears with functional hearing loss, 48 ears with normal hearing, 39 ears with congenital sensorineural hearing loss, 29 ears with presbycusis and 22 ears with occupational noise deafness or others. A comparison of the hearing thresholds in the 440 ears revealed greater than 1 out of 7 frequencies threshold improvements in 48 ears (10.9%), greater than 1 out of 7 frequency deterioration in 30 ears (6.8%), and only one or no frequency threshold differences in 362 ears (82.3%). In the 48 ears with improved thresholds, 38 ears (79.2%) were diagnosed with functional hearing loss. Moreover, 27 ears (6.1%) out of the 440 ears showed over 4 frequencies threshold improvements, and all of these ears were diagnosed with functional hearing loss.
    These results suggest that this novel method, comparing the thresholds measured by continuous versus pulse tones, was useful for the simple screening of functional hearing loss. If a threshold improvement using a continuous tone is observed in more than 1 frequency, then functional hearing loss should be suspected, and threshold improvements in more than 4 frequencies are even more likely to indicate functional hearing loss. For further accurate diagnosis, Bekesy audiometry and auditory brain stem evoked responses are useful.

    The effects of a nonlinear, digital hearing aid on the perception of sentences in a quiet environment were examined for 12 patients with profound sensorineural hearing impairments. This hearing aid was equipped with a compression circuit, which divides the waveform in the time domain by zero-cross points, and then amplifies each waveform to an fixed amplitude. To reduce the susceptibility to background noise, input signals less than a certain level were amplified linearly, and this level was easily adjustable. Three out of 12 (25.0%) patients understood more than 50% of the phrases in typical Japanese sentences at all of the pre-set sound level (50, 60, 70 and 80 dBSPL). Furthermore, this device offered better perception than linear amplification (Rion HA70 or 73) in 8 out of 12 (66.7%) subjects, and was superior to the subjects' own linear hearing aids in 5 out of 10 (50.0%) cases. These results indicate that this hearing aid is beneficial for some subjects.

    A 67-year-old female visited our hospital with a complaint of progressive bilateral hearing loss and recurrent attackes of vertigo. An audiogram showed bilateral sensory neural hearing loss with positive recuruitment phenomenon. The caloric test showed bilateral canal paresis. The galvanic body sway test showed a normal response. From these results, we concluded that the hearing loss, dizziness and equilibrium dysfunction were due to a disorder of the inner ear. The results of a glycerol test and furosemide VOR test suggested endolymphatic hydrops in the inner ear. The patient was treated with steroid and prostaglandin I2. Her dizziness subsequently disappeared, but her hearing loss was not improved. After discharge from our hospital, she entered another hospital because of a high grade fever and muscular pain. Laboratory data suggested an autoimmune disease and renal failure. She was diagnosed with periarteritis nodosa on the basis of clinical findings and pathological findings following a kidney biopsy.

    In order to measure the serum levels of IgG and IgG subclass antibodies against Japanese cedar pollen, an ELISA procedure was developed with commercially available antigen-coated wells for measuring IgE antibodies. The specificity, sensitivity and reproducibility of this ELISA system were all highly reliable in our experiments. The results of this study suggest the clinical usefulness of this method for following the responses of serum IgG and IgG subclass antibodies during immunotherapy for Japanese cedar pollinosis.

    A 24-year-old man was shot accidentally by an air gun. A bullet went through the left eye socket, and a large fragment was lodged in the left sphenoidal sinus. Computed tomography and arterial angiography revealed two fragments. Two months after the imaging studies, a large fragment in the sphenoidal sinus was removed by endoscopic paranasal surgery using an image intensifer. With respect to foreign bodies lodged in the paranasal sinuses, it has been reported that the most frequent site was in the maxillary sinus, followed by the ethmoidal sinus and the sphenoidal sinus. Metallic foreign bodies are generally safer than organic plant foreign bodies which can easily induced an inflammatory process. It is prudent that a foreign body in the paranasal sinus should be removed as early as possible, even if the foreign body is metallic.

    We report a 53-year-old male with leiomyoma in the bottom of the tongue. Computed tomography and magnetic resonance imaging suggested a benign tumor localized in the oropharynx. The patient underwent extirpation of the tumor by a cervical approach. Since the surgery, he has been followed up for six months and to date there is no sign of recurrence.
    Histopathological and immunohistological studies revealed the tumor to be a vascular leiomyoma. Vascular leiomyoma in the head and neck region is a rare disease. This is the first report of vascular leiomyoma arising underneath the tongue, according to a critical review of the world literature up to 1997.

    A 72-year-old male visited our hospital complaining of foreign body sensation in the throat. On fiberscopic examination, we found a round smooth mass with a pedicle arising from the posterior wall of the mesopharynx. The tumor was resected along its capsule using an oral approach, with a preoperative diagnosis of benign tumor. The pathological diagnosis was a liposarcoma of the myxoid type, and radiation therapy was performed postoperatively.
    Although liposarcoma is the second most common soft-tissue sarcoma in adults, the incidence of liposarcoma of the head and neck is low. There have been 41 reported cases of head and neck liposarcoma in Japan, among which only two cases arising from the pharynx have been detected.

    We report the case of a liposarcoma arising in the parapharyngeal space. A 15-year-old boy who had complained of a tumor in the right submandibular region and swelling on the right lateral pharyngeal wall for one month was referred to the University of Tsukuba Hospital for further evaluation. A large tumor was recognized on CT and MRI, extending from the carotid triangle to the skull base in the right parapharyngeal space.
    The tumor was completely removed along with several cervical lymph nodes, and the pathological diagnosis was a “well-differentiated liposarcoma without metastasis to the cervical lymph nodes”. Radiation therapy was performed postoperatively with a dosage of 65 Gy. The postoperative course was uneventful, and there has been no sign of recurrence or metastasis over a 3 year follow-up period.
    Liposarcomas of the head and neck are commonly observed in males 40 to 60 years of age, and their occurence in children is extremely rare.
    In a review of the available literature, this is only the second case of a parapharyngeal liposarcoma in a child reported in English or Japanese literature thus far.

    Twenty-two cases of thyroglossal duct cysts were treated surgically in our hospital over the past 5 years. Histopathological examination of specimens obtained during surgery revealed that thyroid tissue was found in 14 cases of the 22 (63.6%). Since thyroglossal duct cysts are closely related to the generation of the thyroid gland, it is reasonable that thyroid tissue would sometimes be found in thyroglossal duct cysts. Further detailed investigation may reveal the incidence of thyroid tissue in these cysts to be quite high.
    Thyroid tissue in the thyroglossal duct cyst is ectopic, and has a greater tendency to become cancerous than thyroid tissue in normal locations.
    We suggest that thyroglossal duct cysts should be removed surgically at the earliest stage possible, because ectopic thyroid tissue is highly likely to be present.

    A 56-year-old man suffering from a sore throat on swallowing, of six months duration, attended our clinic. There was an elastic hard tumor in the left lobe of the thyroid gland and a swollen jugular chain lymph node was palpable. CT scan showed a non-enhanced mass invading the esophagus, with calcification on the dorsal side of the thyroid gland. A preoperative cytological study using fine needle aspiration diagnosed the tumor as a papillary carcinoma. The patient underwent a left lobectomy of the thyroid gland and left conservative neck dissection. The initial pathological diagnosis was anaplastic carcinoma, and postoperative radiation therapy was provided. However, the clinical course of this patient was not compatible with that of anaplastic carcinoma. The patient was ultimately diagnosed as a case of epithelioid hemangioendothelioma (EH) by immunohistochemical study. EH is a rare tumor, and EH originating from the thyroid gland has not been previously reported.

    Treatment of tinnitus is often difficult. In this study, we evaluated the effectiveness of a Chinese medicine, Gosha-jinki-gan, for the treatment of tinnitus. Forty-two cases, comprising a total of 58 ears, received Gosha-jinki-gan at a dose of 7.5 g a day for at least 4 weeks. Efficacy was evaluated on the basis of changes in symptoms before and after treatment. In total, twenty-seven out of 58 ears (46.6%) improved. The final improvement rate was higher in the group with hearing loss than in the group without hearing loss. It was also greater in the group without pre-treatment than in the group with pre-treatment, however, co-treatment did not influence the improvement rate. No adverse reactions were evident. From these results, it was thought that Gosha-jinki-gan might be useful in the treatment of tinnitus.
