    Olfactory receptor neurons are located in the olfactory neuroepithelium of the nasal cavity. Olfactory neuroepithelilum has an unusual chararacteristic ability to continue neurogenesis throughout lifetime. This unique character provides an elegant model to study neurogenesis, and fascinates scientists in various fields. This unique ability, also, has made olfactory neuroepithelium as one of the best candidates for “regenerative medicine”. This review presents an overview of both physiological and biological data describing the structure and function of olfactory neuroepithelium.

    A 17-year-old female with right deafness developed sudden left hearing loss without vertigo. She admitted to our hospital with an idiopathic fever that persisted for 3 months. Sensory hearing loss on both sides and inflammation shown on immunological blood examination were noted on admission. We pointed out differences in blood pressure between the radial artery and femoral artery. Magnetic resonance imaging and computed tomography showed complete occlusion of the left carotid artery with some calcification. We considered that hearing loss in this case might be associated with aortitis syndrome and continuous steroid therapy was administered. Physical findings and hearing were improved gradually.

    Sensorineural hearing loss is a well known complication of mumps described as “mumps deafness”. Incidence of mumps deafness has been regarded as rare, to the order of 1/10, 000-20, 000 cases, although the disease can cause permanent profound unilateral deafness. The authors present 12 cases of mumps deafness treated at Tokyo Medical University Hospital during a 15-year period. Ten patients complained of unilateral deafness, and two displayed bilateral deafness. Hearing partially improved in one case, although 11 cases were resisted to treatment. Cochlear implantation was performed in two cases of bilateral deafness. Postoperative course of these two cases was satisfactory, suggesting that patients with mumps deafness are potentially good candidates for cochlear implantation.

    We report two cases of ossicular lesions correctly diagnosed with three-dimensional CT (3D-CT). The first patient was a 28-year-old male, who had hearing loss in the right ear after a sneeze. The other patient was a 50-year-old male complaining of left ear hearing loss after a head injury. Almost normal hearing was obtained after tympanoplasty type IV-c (case 1) and partial stapedectomy (case 2). Both patients underwent operations by transcanal approach.
    We were able to make exact diagnoses before operation by 3D-CT in both cases, and 3D-CT reconstruction of the operation field was suitable for modeling of the operations. These cases suggest that 3D-CT is useful not only as a method for diagnosing ossicular lesions, but also as a method for preoperative surgical planning.

    Excellent response to HDST has been reported in patients with idiopathic facial nerve palsy. However, surgical decompression of facial nerves in severe cases remains controversial. In this study, outcomes obtained through HDST and those obtained through conventional therapy were compared, and the outcomes of decompression surgery after medical treatments were analyzed.
    Subjects were 119 outpatients with severe facial palsy treated at our clinic, who satisfied the following criteria: 1) the first treatment was performed within 3 weeks after onset; 2) grade of palsy was scored as less than 10 of 40. Sixty-one (Group A) patients were treated with our conventional therapy using dexamethazone between 1984 and 1989, and 58 (Group B) with HDST between 1990 and 2001. Eighteen patients (29.5%) in Group A and 7 (12.1%) in Group B underwent surgery due to the absence of satisfactory response to medical treatments and poor electrical-test results.
    Seventeen (73.9%) of 23 patients with Bell's palsy in Group A and 18 (94.7%) of 19 in Group B, and 1 of 2 patients with Ramsay Hunt syndrome in Group A and 9 of 12 in Group B, showed complete recovery with medical treatment only and did not receive surgical treatment. Among patients receiving surgical decompression, only 1 in Group A and none in Group B showed complete recovery.
    As a results of medical treatment, palsy improved and the number of patients undergoing surgical treatment decreased after introduction of HDST. Surgical outcomes of surgery in severe cases were not satisfactory, suggesting the limitations of surgery.

    We examined the causes of ear fullness in 1980 patients.
    Most female patients with ear fullness at our hospital were aged from their twenties to sixties and many tubal diseases caused ear fullness.
    Among external ear diseases, ear wax and otitis external must often caused ear fullness.
    Traumatic perforation of the tympanic membrane often required admission in youths, and tubal diseases were common in females of all ages.
    Among middle ear diseases, otitis media with effusion was often seen, while in patients with inner ear diseases, sudden deafness was frequent.

    1. Five cases of parotid cancer are reported, in which the patients underwent parotidectomy under diagnosis of benign tumor in another hospital or department, were postoperatively diagnosed with malignant tumor, and then received reoperation in our department.
    2. The age and sex distribution of the cases was 3 males and 2 females with a mean age of 40 years, ranging from 10 to 77 years, including 2 child cases under 15 years.
    3. Histopathologically, the cancer was classified as adenoid cystic carcinoma in 2 cases, mucoepider-moidcarcinoma in 2 cases, and acinic cell carcinoma in 1 case, and one each of adenoid cystic carcinoma and mucoepidermoid carcinoma occurred in the children.
    4. The patients underwent reoperation within 8 weeks after the first surgery. The surgical technique was total parotidectomy in 1 case and superficial lobectomy in the remaining 4 cases, with the facial nerve being preserved in all 5 patients.
    5. Palpation in the examinations conducted at follow-up in our department detected no localized tumor remnant, but the tumor was still found to be histologically residual in 4 of the 5 cases.
    6. The postoperative clinical course was found to be excellent, without recurrence or metastasis of the cancer.

    We reported a case of a young woman who underwent removal of parapharyngeal tumors by way of midline mandibulotomy with elevation of visor (strap) flap. It is not necessary to split the lower lip in this approach, which allows a wide view of the parapharyngeal space by retracting the mandible laterally and superiorly and carries little risk of cosmetic and functional complications.

    Sixty-seven patients with squamous cell carcinoma of the hypopharynx were treated at the Kochi Medical School from 1983 to 1999. Of the 67 patients, 63 were male and 4 were female, and the mean age was 62 years. The locations of primary lesion were the pyriform sinus (45 cases), the posterior pharyngeal wall (11 cases) and the postcricoid (11 cases). Three cases were in stage I, 9 in stage II, 17 in stage III, 38 in stage IV.
    As for the primary treatment, 50 of 67 patients were treated with preoperative irradiation of 20-30Gy followed by surgery, and 16 patients were treated with irradiation alone. One patient had no treatment because of poor general condition.
    The cause-specific survival rate (Kaplan-Meier method) of all patients was 43.5% at 5 years. In patients receiving the definitive treatment, N stage was significant for overall survival, but T stage was not.

    Basaloid-squamous carcinoma (BSC) is a high grade, aggressive variant of Squamous cell carcinoma (SCC). The incidence of BSC of the head and neck generally has been low, although the number of case reports has increased in recent years.
    We report a case of BSC localized in the larynx. The biopsy specimen of the larynx suggested SCC initially, but further biopsy ultimately revealed BSC, subsequent endoscopy revealed simultaneous SCC in the esophagus. The patient was treated with surgical resection of the larynx, hypopharynx, and esophagus, and dissection of the neck bilaterally. However, bilateral lung metastasis appeared 3 months after surgery, and he died 5 months later.
    BSC of the head and neck region is a highly malignant neoplasm with frequent metastatic complication. Therefore, it is important to distinguish BSC from conventional SCC. Even if it is an early stage, in addition to resection of the primary neoplasm and dissection of the neck, it is essential to perform powerful whole body treatment.

    We report a case of intramuscular hemangioma in the sternocleidomastoid muscle in a 12-year-old female. The tumor had slowly enlarged up to 35mm length in the left sternocleidomastoid muscle. MRI was a useful tool for both diagnosis and therapeutic planning. The tumor with surrounding muscle tissue was surgically excised, without excess bleeding. After the surgery, neither deformity nor functional problems of the neck have appeared in follow up.

    Between 1982 and 2001, 50 cases of deep neck infection were treated in our hospital. This study reviewed the management of deep neck infection, referring to primary focus, pathogenic bacteria, administration of antibiotics and surgical treatment. Fifty cases were classified by two groups according to the duration of admission, the severe group (more than 2 weeks) and the mild group (less than 2 weeks). Characteristics of these two groups were compared to identify factors affecting severity. This investigation indicated that the factors which affect severity were age, interval from onset to initial diagnosis, site of abscess formation and immunosuppression.

    Retropharyngeal abscess which is usually seen in children under 6 years of age is a serious complication of pharyngeal infection. We described retropharyngeal lymphadenitis of an eight-year-old boy who was misdiagnosed as having a retropharyngeal abscess. On May 12th, 2000, he was admitted to our hospital for pain and swelling of the left neck and trismus. Contrast-enhanced CT showed 20×25mm low attenuation mass with ring enhancemant on the left side of the retropharyngeal space and a low density mass in the retropharyngeal area. Surgical drainage was performed, but there was no pus recognized. The patient also had multiple swollen cervical lymph nodes, and a biopsy was performed on one of them. The pathological diagnosis was reactive lymphadenitis. The patient responded to antibiotic therapy. In children under 6 years of age, lymph nodes in the retropharyngeal space are well developed compared with those of adults. For this reason, retropharyngeal abscess more easily occurs in children than adults. Published CT criteria for diagnosis of retropharyngeal abscess have included focal low attenuation mass sometimes with ring enhancement. In this case, the reason why a retropharyngeal abscess was thought possible was that contrast-enhanced CT of lymphadenitis demonstrated an image resembling deep neck abscess. Glasier et al reported that ultrasound (US) was useful in distinguishing retropharyngeal abscess from adenitis in children. When a diagnosis is difficult, US examination should be performed to correctly diagnose the condition and avoid unnecessary surgical intervention in children with retropharyngeal adenitis without abscess.

    We report the case of a 19-year-old female with a gunshot wound penetrating from face to neck, caused by a handgun in Wakkanai City, Hokkaido.
    Upon arrival at our hospital, she was conscious and in good general condition. We found wounds on her right face and left neck, and suspected gunshot injury from the defect of skin with burns around the wound on her face. Injuries to the basal part of the right inferior turbinate, the bottom of the left tonsil, and the center of the hard palate were seen. From the skin defect, we concluded that the bullet penetrated from face to neck, passing through the right maxillary sinus, nasal cavity and oral cavity. After the operation to suture the wound under general anesthesia, we found paralysis of the left glossopharyngeal, vagus and hypoglossal nerves and sympathetic trunk as shown by dysphagia, hoarseness, deviation of tongue, and Horner's syndrome. She achieved oral intake of jelly after 3 weeks of swallowing training, and 15 months later, she recovered from the paralysis.
    We decided that the important arteries and veins in her neck weren't destroyed by the bullet. Among domestic reports of gunshot wounds, there were no cases of paralysis of multiple cranial nerves except for our case.
