    Twelve cases of acute sensorineural hearing loss induced by loud discotheque music are reported. Patients consisted of 4 men (7 ears) and 8 women (12 ears). Seven had bilateral and five had unilateral involvement. Dip-type hearing loss was observed in seven cases, while U-type, flattype, reversed U-type, and high tone loss type were also observed. In relation to age, most of the cases occurred in teenagers and those in their twenties. When the dip-type is compared with other types, it is more likely to occur bilaterally and sometimes after exposure to loud noises, but has a good prognosis. Other types are more likely to occur unilaterally following exposure to loud sounds, and have a poor prognosis. Therefore, the dip type and other types appear to have different pathogenese in the development of hearing loss. That is to say, the dip type is “delayed recovery NITTS” while other types are considered “PTS” because of their poor prognosis.

    The etiology of sudden deafness is unknown, but ischemia of the inner ear is believed to be one of the major causes of sudden deafness. We administered Batroxobin for over 28 days at dosages of over 150 B. U., to 10 patients with sudden deafness. After this treatment, the hearing level improved significantly in 9 out of the 10 patients. The less satisfactory result in the one patient could be attributed to a failure in the control of his plasma fibrinogen levels. We believe that this therapy can be very effective, provided that the side effects of this therapy are well understood by both patients and the medical staff.
    The treatment of sudden deafness with Batroxobin is discussed in this report, based on our experiences with long term defibrinogenation therapy.

    The reconstruction of bone defects in the middle ear is necessary when the bone defect is adjacent to diseased tissues, or when the bone must be removed to eliminate a pathological condition. Various materials have been used to reconstruct such bone defects. However, autologous bone is still considered to be the most suitable material for this type of reconstruction. We have used a mixture of autologous bone chips and paté for this purpose of reconstruction, and have obtained satisfactory results.
    The usefulness of this method was reported for the following representative conditions: (1) obliteration of the mastoid cavity, (2) reconstruction of the ear canal wall, and (3) closure of a labyrinthine fistula.

    This study included 202 patients who were tested by routine allergic examinations for their nasal symptoms. Each patient was examined by the skin test, CAP system (CAP, Lumiward Immunoassay System (LMD)), the nasal provocation test, and a nasal smear test for the diagnosis of Japanese cedar pollinosis. A special comparison was performed between the skin test, the CAP and LMD in the detection of Japanese cedar-specific IgE antibodies. The following results were obtained:
    1. The values for IgE antibodies as determined by the LMD were strongly correlated with those determined by CAP.
    2. The sensitivity of the LMD in the detection of Japanese cedar-specific IgE antibodies was higher than the skin test or CAP. The use of LMD was considered to be especially useful in the diagnosis of cedar pollinosis in patients with low serum IgE antibody levels.
    3. The specificity of the LMD and CAP was better than the skin test.
    4. A combination of the skin test and LMD should be recommended clinically as a screening test of Japanese cedar-specific IgE antibodies.

    Our patient suffered a left buccal lesion in a fall. A fragment of a leaf was removed by her family doctor. However, a trismus continued. Ten days after the injury, she was referred to our hospital. There was fistula formation with purulent discharge from the wound. No foreign bodies were reliably detected by a CTscan. We then used MRI for the diagnosis of a foreign body. A wooden foreign body with a high signal was found in the masseteric muscle on T2-weighted imaging. After the removal of the foreign object, the trismus recovered quickly.
    MRI is not necessarily recommended as a routine examination in the diagnosis of a foreign body. However, if a wooden foreign body is suspected and cannot be detected by CT scan, then MRI should be applied.

    For postoperative maxillary cyst (POMC), the per-maxillary method has been performed in most cases. The endoscopic endonasal method has had only limited application, since the varied number and location make the operation difficult. Recently, we have started using the endoscopic endonasal method on all POMC cases. We discuss the indications for the use of the endoscopic endonasal method for POMC based on the results of these operations. This study comprised 55 patients (59 sides), 18 females and 37 males, who underwent the endoscopic endonasal method for POMC from January 1990 to June 1994. We followed these patients for 1-year postoperatively.
    We found that the wall of the cysts opened to the nasal cavity in 91.5% of cases. When there was only one cyst, the partition wall between the cyst and the nasal cavity was menbranous and/or the cyst adjoined the wall of the nasal cavity, almost all cysts opend to the nasal cavity. When the cysts had bony wall and/or were apart from the nasal cavity, it was possible for the wall opening to be blocked or restricted.
    Based on our results, we conclude that a minimally invasive endoscopic method should be the operation of first choice for POMC.

    Pleomorphic adenoma is the most common tumor in the major salivary gland, but it is rare in the sublingual gland. A 24-year-old female was referred to our hospital with a chief complaint of snoring. CT, MRI and pathological examination confirmed the diagnosis of pleomorphic adenoma of the sublingual gland. Complete resection of the tumor was carried out. Post-operatively, the patient did not snore. There has been no evidence of recurrence after two years follow-up.

    We report here 2 cases of parotid abscesses which were difficult to distinguish from malignant tumors.
    Case 1. A 5-y.o.-male had a sudden right parotid swelling without any particular inducement. There were no signs of inflammation based on clinical symptoms or laboratory data. A malignant tumor was suspected based on indications by both the cold image on the Tc scintigraph and the hot image on the Ga scintigraph. Surgical observation recalled that there was an abscess formed in the parotid gland, and its wall adhered to the facial nerve.
    Case 2. A 70-y.o.-male with diabetes mellitus had been treated with oral medicines. He had left parotid swelling with pyrexia and pain and had left facial nerve paralysis as well. Since there was the possibility of a malignant tumor because of the facial nerve paralysis, we performed a biopsy through the ulcer. However, there were no neoplastic changes, only inflammation. Surgical observation showed that the parotid gland was scarred and no tumor tissue was observed. The adhesions to the facial nerve were friable and not hard.
    According to the pathologic diagnosis, both cases had chronic parotiditis with abscess formation. A conclusive observation which distinguishes a benign tumor from a malignant tumor is not available for inflammation of parotid gland. In case 1, there were no signs of inflammation, and the hot image on the Ga scintigraph were suggestive of a malignant process. In case 2, the existence of the facial nerve paralysis made it difficult to distinguish from a malignant tumor.

    A case of congenital pharyngeal teratoma in a 18-day-old newborn girl is reported.
    The patient was referred to our clinic with a complain of dyspnea during suckling. There was no causative past history such as infection or medication, and family history was not contributory. On physical examination, the large mass was noted in both the pharyngeal and oral space, and X-ray examination revealed a mass chiefly occupying the mesopharyngeal space. Following surgical extirpation, the mass was found to be pedunculated tumor arising from the left palatine tonsil. The pathohistological diagnosis was teratoma because the mass consisted of both ectodermal (skin) and mesodermal (cartilage and fat) tissuses.
    Congenital teratoma originating from the pharynx seems to be rare. We discuss this case from the perspectives of clinical features, pathogenesis and treatment.

    Mycotic aneurysms of the extracranial carotid artery are rare lesions. We describe a case of mycotic extracranial carotid aneurysms developing after a parapharyngeal space infection in a 65-year-old-man. The patient had a high fever because of tonsillitis, and it spread to the parapharyngeal space. After the inflammation had passed, a pulsatile mass appeared around the pharynx. Extracranial aneurysms are diagnosed by MRI and DSA (angiography), and are treated with intravascular techniques using mechanical detachable coil (MDC).

    We studied the expression of proliferating cell nuclear antigen (PCNA) in surgically resected thyroid follicular tumors using immunohistochemistry. We also analyzed PCNA expression in preoperative fine needle tissue biopsy specimens of these tumors.
    Twelve surgically resected tumors were divided into 8 follicular adenomas and 4 follicular carcinomas. Preoperative fine needle tissue biopsy was performed in 10 of these tumors using a 21-gauge Surecut needle. The mean PCNA positive rate in the surgically resected tumors was 0.65% in the follicular tumors and 3.85% in the follicular carcinoma, and there was a significant difference (P<0.05) between the two groups. In the preoperative fine needle tissue biopsy specimens, the PCNA positive ratio was higher in the follicular carcinoma (mean 2.8%) than the follicular adenoma (mean 0.52%). These findings indicate that the PCNA-positive rate reflects the relative malignancy of follicular tumors. The combination of fine needle tissue biopsy and PCNA positive ratio may be useful in distinguishing follicular carcinoma from follicular adenoma preoperatively.

    Much international attention has been recently paid to cochlear implant in children as one of the most important issues in otology. This report attempts to establish our policies for indications for surgery, mode of surgery and rehabilitation.
    Regarding the indications, they should be determined according to the patients' age, hearing acuity, and the radiologic findings of their ears. The surgery should be performed carefully considering the thickness of the cortical bone of the temporal region, and also the thickness of the skin. The rehabilitation should be performed patiently by experienced personnel, since children require a longer period than adults.
    Cochlear implants should be done on younger children because the neural plasticity of the cerebral cortex for speech perception is better in a younger population. It is also important for us to cooperate with local educational staffs such as school teachers and deaf-school teachers to facilitate the rehabilitation of children with cochlear implants.

    Obstructive sleep respiratory disorders (OSRD) are breathing disorders occuring during sleep, which include snoring and sleep apnea syndromes.
    Twenty-two adult patients who had been diagnosed as having OSRD underwent polysomnographic examination with two point baroreceptors, one in the esophageal area and the other in the mesopharyngeal area. We could find the site of obstruction by simultaneous two point pressure measurements. There were four types of OSRD: the transfer type (Group A, n=1), root-of-tongue type (Group B, n=5), combined type (Group C, n=3) and soft-palate type (Group D, n=14).
    The mean followed by that in the intraesophageal pressure (EP) was highest in the root-of-tongue type. The combined type was higher that in the soft-palate type. Apnea index was greatest in combined type than followed by that in the soft-palate type. The decrease of SaO2 then in the root-of-tongue type and combined type patients were the most obese.
    The correct diagnosis of the area of obstruction and the selection of the operative method most appropriate for that area are very important.

    Emedastine difumarate is a selective H1-antagonist as well as a histamine release inhibitor. The effects of emedastine on patients with allergic rhinitis have been previously reported. We examined the effects of emedastine difumarate (0.03, 0.3 and 1.0mg/kg) on nasal symptoms, changes in the total airway resistance (TAR) and eosinophil infiltration into the nasal mucosa induced by topical antigen challenge in actively sensitized guinea pigs.
    Nasal symptoms (the number of sneezes and scratches) were significantly inhibited by emedastine pretreatment in a dose dependent manner. We noted a biphasic increase in the TAR after antigen challenge. The first peak response of the TAR was partially but significantly inhibited by emedastine (0.3 and 1.0mg/kg). The second peak response of the TAR was also inhibited by emedastine (1.0mg/kg). Furthermore, emedastine (1.0mg/kg) significantly inhibited antigen-induced eosinophil infiltration into the nasal mucosa.
    In conclusion, our results suggest that emedastine difumarate may suppress nasal symptoms in guinea pig models of allergic rhinitis.
