    Image diagnosis of sensorineural hearing loss was discussed with the presentation of examples of magnetic resonance imaging (MRI) and computed tomography (CT). MRI and CT of acoustic tumor, congenital perilymphatic fistula, brain stem infarction in the region of the anterior inferior cerebellar artery, inner ear hemorrhage, congenital ipsilateral profound hearing loss or sudden sensorineural hearing loss associated with inner ear anomaly, large vestibular aqueduct syndrome, superior canal dehiscent syndrome, large internal auditory canal syndrome, cochlear otosclerosis, and idiopathic low cerebrospinal fluid pressure syndrome were presented. In large vestibular aqueduct syndrome, superior canal dehiscent syndrome and large internal auditory canal syndrome, air-bone gap exist. As the explanation of the air-bone gap, we propose “three windows” model when there is a wide non-osseous communication route between the inner ear and the cerebrospinal fluid.

    We report seven cases of juvenile nasopharyngeal angiofibromas (6 males and a female, averaged 17.3 years old) treated at Mie University Hospital for 20 years during 1983 and 2003. Tumors ranged from 20 to 90mm, but these size was not related to tumor stage. In patients, the surgery was performed by a trans-oral (4 cases) or trans-maxillary (3 cases) approach. In two cases, palatal fistula was observed, and later closed surgically. Two recurrent tumors were observed at about one year postoperatively and those cases were successfully underwent surgery again by the trans-maxillary approach. Intraoperative blood loss volume was large in advanced staged cases, but the volume was not related to tumor size. Pre-operative thrombosis via a maxillary artery under angiographic guidance, was performed in each case. This treatment was effective, when performed the day before surgery.

    Two cases of olfactory disturbance caused by large concha bullosa were reported. Severe stenosis of the olfactory cleft caused by concha bullosa swelling was revealed through coronal scanning by computed tomography (CT). There was little inflammation. Olfactory improvement was correlated with removing the stenosis around the olfactory cleft by endoscopic sinus surgery (ESS). It is considered that detailed examination of the olfactory cleft and coronal scanning by CT are important in cases of olfactory disturbance.

    Malignant peripheral nerve sheath tumor (MPNST) is a rare neoplasm of nerve sheath origin. We report a case of MPNST arising in the mandible with bone destruction.
    A 55-year-old man presented with a 3-month history of slowly progressive, painless swelling anterior to his left ear. MRI imaging demonstrated a well-circumscribed mass in the ramus of his mandible with bone destruction. Surgical excision was performed. Immunohistochemically, the tumor cells were stained for S-100, leading to a diagnosis of MPNST arising from the trigeminal nerve. A total dose of 60Gy radiation was delivered postoperatively. There has been no evidence of recurrence 9 months postoperatively. Because MPNST often recur and metastasize after surgical excision, careful follow-up over a prolonged period is important.

    We report three cases of large radicular cyst, successfully resected by endoscopic endonasal surgery. Radicular cysts were opend by partial resection from the medial wall of the maxillary sinus in the inferior meatus. This procedure is similar to the surgery for postoperative maxillary sinus cyst, therefore it is a simple technique for oto-rhino-laryngologists. This approach is very useful for large radicular cyst because it is less invasive to the patient than a conventional approach. Surgeons should pay attention to the residual cystic cavities and residual cyst walls, when performing this procedure.

    Blindness is rarely reversed. We report a 78-year-old female with acute traumatic blindness, which was cured by surgical treatment. She suffered a blunt injury to her right eye caused by a wooden foreign body penetrating through the upper lid. Computed tomography showed an orbital hematoma compressing the optic nerve. The hematoma was surgically removed 6 hours after the accident. Postoperatively, the patient was treated with intravenous corticosteroids in a tapering regimen for 4 days and intravenous antibiotics for 4 days. The visual acuity of her right eye improved progressively from the first postoperative day. One and a half months later, the right visual acuity improved to 0.15, the same as that of the left.
    Orbital hematoma is a rare complication resulting from blunt periorbital trauma, usually treated by conservative therapy only. If, however, the proptosis becomes dangerous or severe visual loss presents, surgical treatment should be selected.

    Pyogenic granuloma is a benign tumor of the dermis and mucosa. This disease is often seen in the oral and nasal cavity, however, it is rare in the hypopharynx.
    We report a case of pyogenic granuloma in the hypopharynx.
    An 84-year-old male with pharyngeal pain and hemoptysis was referred to our hospital. Laryngoscopy showed a mass located at the left side of the hypopharynx. This mass was dark red and had a stem. It moved up and down in accordance with breathing. Tracheostomy was performed under local anesthesia and the mass was removed under general anesthesia with a YAG laser using a laryngomicrosurgery technique. The histological findings showed pyogenic granuloma. Ulcerous and erosive lesions were observed on the surface of the specimen and candida-like fungus and bacteria were recognized. We considered that infection played an important role in the presence of the pyogenic granuloma in the present case.
    The features of pyogenic granuloma were reviewed.

    Neurinoma of the base of tongue is relatively rare, and only 36 cases have been reported in Japan so far.
    We reported a case of a 30-year-old female suffering from giant neurinoma (of the size of 50×45×40mm) of the base of tongue, who underwent removal of the tumor by an intraoral median glossotomy translingual approach. It is not necessary to perform pharyngotomy or mandibulotomy with this approach, which allows a wide view of the root of the tongue and carries little risk of cosmetic and functional complications.

    We reviewed the treatment of 86 patients with peritonsillar abscess.
    Using multivariate analysis, we examined whether the (1) laterality, (2) age, (3) gender, (4) surgical procedure, (5) isolated bacteria, or (6) intravenous antibiotics influenced the treatment period. We also examined whether the (1) surgical procedure, (2) isolated bacteria, or (3) antibiotics administer influenced the recurrence of peritonsillar abscess, by multivariate analysis. Regarding surgical procedure, puncture extended the treatment period. Strept. pneumoniae as the bacteria isolated also extended the treatment period.
    The recurrence rate was influenced by isolated bacteria and otolaryngological treatment.
    Among the 86 cases, 16 cases (19%) had recurrence after discharge, with 24 relapses in total. Eleven cases (13%) had recurrence within one month after discharge.

    Recently, the use of clinical pathways has been introduced as a tool for improving medical quality in Japan. We applied a clinical pathway to the care management following tonsillectomy in adults and evaluated the outcome. In our pathway, sore throat, hemorrhage, diarrhea and fever elevation were the variables examined following tonsillectomy. For reduction of the level of these variables, in addition to our previous treatments, morphine was given at a dose of 20mg per day for 2 days following the operation, and pre-operative antibiotic therapy was introduced. As a result of these changes, we observed the decreased appearance of sore throat, diarrhea and fever elevation after tonsillectomy.

    We investigated the clinical results of 73 patients who had tracheal invasion of thyroid carcinoma (papillory carcinoma and folliculor carcinoma) and received surgical treatment between 1978 and 2003 at Kurume University Hospital. The 10-year local control rate was 95% in the patients without tracheal invasion and 74% in those with tracheal invasion. There was a significant difference between the two groups (p<1%). Extensive resection of the trachea was performed in 37 out of the 73 patients. In 33 patients, the defect in the tracheal wall was reconstructed secondarily using a local flap such as the nasal septum cartilage or hydroxylapatite. An end-to-end anastomosis was performed in four patients with extensive invasion to the membranous portion of the trachea. End-to-end anastomosis is the most effective, physiological method of reconstructing the airway because of its full diameter and mucociliary function.

    Twelve patients with mucosal melanoma of the head and neck were treated in our department between 1984 and 2003. The patient population included five men and seven women, aged 45 to 88 years (mean: 63 years). In six cases, the tumors were localized to the nasal cavity and the paranasal sinuses, in four to the oral cavity, in one to the lacrimal sac, and in one case the primary tumor was unknown.
    They were treated with or without multimodal surgery, radiation, chemotherapy, hormonal therapy, and immunotherapy. The 5-year survival rate of all patients was 50%. The survival rates of the patients treated with or without radical surgery showed no difference. However, one patient treated with radical surgery lived for a long term (over 12 years). All patients treated without radical surgery showed local recurrence. The effectiveness of radiation, hormonal therapy and immunotherapy in our patients was not observed.

    Nevoid basal cell carcinoma syndrome (NBCCS) is a rare autosomal dominant disorder characterized by odontogenic keratocysts, palmar or plantar pits, ectopic calcification, and occurrence of various types of tumors, including multiple basal cell carcinoma. NBCCS is caused by mutations in the patched gene (PTCH), and shows a homologous type of the Drosophilia segment polarity gene (Ptch). PTCH is a tumor suppressor gene located at 9q22.3.
    In this paper, two cases of NBCCS in one family, in a girl and her mother are presented. Case 1: An 18-year-old female complaining of painful swelling in the right mandible. CT revealed a cystic lesion in the right maxillary sinus and calcification of the falx cerebri and tentorium cerebelli. Radical operation of the maxillary sinus was performed. Histological examinations revealed odontogenic keratocyst. Case 2: A 48-year-old female, the mother of Case 1. Her CT revealed calcification of the falx cerebri and tentorium cerebelli. She had also dental cyst. The clinical features of these two cases met the proposed diagnostic criteria for NBCCS.

    The effect of the power setting of a bipolar radiofrequency system (CelonLab ENT) on coagulation range and duration was evaluated using chickens at power settings of 4, 8, 12, 16, 20, and 24W. Regression analysis revealed a significant correlation between coagulation range and power (P<0.0001, R2=0.71), with a larger area being coagulated at a lower power setting. There was also a significant correlation between coagulation time and power (P<0.0001, R2=0.75), with a shorter duration being required at a higher power setting. Although human and chicken tissue may exhibit different characteristics, our current results suggest that the power level should be altered by surgeons in accordance with coagulation requirements during a procedure.
