    The nasopharyngeal mucosa is the first line of defense of the upper respiratory tract (URT), protecting it from invading foreign antigens. It is well known that the mucosal lining of the URT is equipped with non-specific and specific defense mechanisms. Thanks to new advanced molecular biology techniques, the nasopharyngeal mucosa has become to the focus of investigations on local immune response, in order to use it clinically in vaccination therapy against microbial infections or in hyposensitization therapy for nasal allergies. Therefore, it is very important for otolaryngologists to have a better understanding of the mechanism of mucosal immunity in the nasopharynx, because so many kinds of upper respiratory infections and also allergic inflammation, have to be treated by ideal therapeutic strategies.

    The nasal mucosa is characterized by the presence of the cavernous venous plexus, the so-called “volume blood vessel.” Swelling of the nasal mucosa is thought to depend on the degree of blood congestion in the cavernous venous plexus. Laser Doppler (LD) velocimetry is a relatively uninvasive procedure that allows the blood velocity in the nasal mucosa to be continuously measured. A significant reduction in the LD value is associated with nasal allergies and subjective manifestations. Assessment according to three major symptoms of nasal allergy (sneezing, nasal discharge and nasal stenosis) revealed no significant differences in LD values between patients with or without sneezing or nasal discharge. However, the LD values in patients with nasal stenosis were significantly lower than inpatients without. Based on these findings, LD velocimetry appears to be a useful method for objectively assessing nasal allergy, particularly nasal stenosis.Key words : laser Doppler velocimetry;blood velo-city;nasal stenosis

    The subjects of our study consisted of patients who snord or had sleep apnea and were scheduled to undergo uvulopalatopharyngoplasty (UPPP). We divided the 103 subjects into three groups and performed mesopharyngometry on the third group, 55 subjects, before and after surgery.
    The mean length of the soft palate decreased from 27.2mm to 19.5mm. The distance between the two post-palatal arches and the uvula base to the tongue base were significantly longer. The mean ratio of the length of the hard palate to the length of the soft palate increased from 2.1±0.5 to 2.8±0.6 following surgery. These results indicate that the extent of the excision should be determined by the length ration of 3 to 1 between the hard palate and soft palate.
    The subjects with UPPP had marked mesopharyngeal narrowing prior to surgery, compared to subjects with simple chronic tonsillitis, who did not snore or have sleep apnea. Our study found the mesopharyngometry to be a simple and useful method of evaluating oropharyngeal dimension for the UPPP procedure.

    Closed laryngeal injury is a form of airway damage caused by blunt external force to the neck. Because it is unassociated with superficial skin damage, the larynx must be carefully examined to prevent the development of serious respiratory impairment.
    We encountered 2 cases in which laryngeal injury was caused by stranuglation with a necktie. All of the cases were characteristically caused by the impact of direct external force on the larynx. The mechanism of laryngeal injury in our patients is similar to that occurring in neck injuries produced by steering wheels in traffic accidents or by powerful transient compression associated with sports accidents.
    This means that laryngeal injuries are associated with various pathological conditions, such as contusions, catrilage and bone fractures, and acute dyspnea, depending on the condition of the mucosal lining. surrounding tissue. and frame-work.
    All two patients had contusions, according to the degree of their injuries.
    Clinical symptoms improved in response to conservative treatment with antibiotics and steroid agents in all patients.Since no treatment strategy for closed laryngeal injury has yet been established, determination and management of the pathology is extremely important early. With this in mind, careful observation is needed to prevent the rapid onset of dyspnea, even when the laryngeal injury appears to be mild.

    Acute mastoiditis may be responsible for significant morbidity and life-threatening disease. The present study included 11 children who were diagnosed as having acute mastoiditis and were treated at Teikyo University Hospital between 1989 and 1998. We analyzed their symptoms, clinical characteristics, microorganisms isolated from the ears, treatment, and clinical course. In addition, we compared the patients with acute mastoiditis reported in the literature between 1981 and 1990 and 51 patients reported since then, including our 11 children. The following results were obtained. 1) Recent acute mastoiditis mostly occurred following the first episode of acute otitis media in children aged 2 years or younger. 2) The most frequent microorganism isolated from the ear was Streptococcus pneumoniae, and among them, the incidence of PISP/PRSP has increased. 3) The incidence of mastoidectomy has not decreased in recent years. Surgical managements such as incision/drainage or mastoidectomy should always be considered when periosteal abscess or osteitis seem to persist.

    A 66-year-old male was admitted to our hospital with complaints of sudden hearing loss in his right ear and vertigo. The patient had a history of hypertension and diabetes mellitus. No other neurological deficits were noted. Neurootological examinations revealed sensorineural hearing loss and a horizontal gaze nystagmus. Right facifal and trigeminal nerve paralysis appeared 5 days later. CT and MR' examinations revealed a lesion, suggesting an infarction in the region of the anterior inferior cerebellar artery (AICA). Infarction of the AICA should therefore be considered in patients at risk for arteriosclerosis who present with a sudden hearing loss and vertigo.

    A 65-year-old woman had sudden onset of bilateral facial palsy.Initially, the patient showed disturbance of movement on the right side of the face, which improved by administering steroid hormone by intravenous infusion. However, 31 days later, the patient developed facial palsy, on the left side of the face. Once again, steroid hormone was administred intravenously, and the patient's condition recovered normal facial movement.
    Clinical examination revealed unremarkable physical characteristics except for the facial palsy. Chemical analysis of blood showed normal values. Both radiographic and magnetic resonance imaging (MRI) examinations of the ear demonstrated normal results. However, serological analysis revealed high antibody titers to herpes simplex virus (HSV) and to cytomegalo virus (CMV).
    Therefore, we were unable to rule out the possibility that the facial palsy may have resulted from a viral infection. Nevertheless, we strongly believe that the definitive diagnosis should include viral infection.
    Bilateral facial palsy is a rare condition. We diagnosed this case as bilateral heterochronous facial palsy.
    The majority of bilateral facial palsies are caused by Bell's palsy. However, we believe that it is necessary to also consider other causes such as systemic diseases, and sarcoidosis.

    Even with the advanced antibiotics available today, deep neck abscesses can cause severe complications resulting in critical conditions unless treated carefully and quickly. We treated fifteen deep neck abscesses and one case of mediastinitis between March 1994 and April 1996. In cases where an abscess is recognized, immediate surgical drainage is more effective than conservative therapy. When deep neck abscesses are accompanied by diabetes or old age, however the possibility of a longer recovery period should be taken into consideration.

    Between July and August 1999, we performed image-guided endoscopic endonasal sinus surgery using a powered instrument on seven patients with paranasal cysts. Four of these surgeries were for postoperative maxillary cysts, one was for a postoperative ethmoidal cyst, one for a primaly frontal cyst, and one for a postoperative front-ethmoidal cyst. The advantages of using an optical 3-dimensional navigation system (EVANS III ; Tomiki Corp., Japan) with a powered instrument (XPS Drill-System ; Xomed Corp., USA) for intranasal surgery were then evaluated. The EVANS III is composed of a workstation, CCD camera, a metal probe with three mirror markers, and a headsensor with four light-emitting diodes (LEDs). The optical digitizer is mounted on a stand located 1.5-2 : 5 meters away from the patient's head. This system uses the patient's preoperative image data sets (CT/MRI) to create a 3-dimensional reconstruction. The position of the probe's tip is visualized using triplanar (axial, coronal and sagittal) views of the 2 -dimensional images and/or a 3-dimensional reconstruction at the center of the crosshairs. The 3-dimensional navigation system allows the surgeon to determine the approximate location and direction of each cyst wall and the appropriate point of incision into the nasal cavity. The XPS Drill-System can be used to drill through bone and was used in five cases to open the bony portion of cysts. Anatomical structures such as the frontal sinus and the maxillary sinus are difficult to reach using a straight blade, but can be easily reached using a curved blade (40 degree angle cutter, 55 degree angle drill bar). The curved blade cutter and drill bar enables maxillary, ethmoidal and frontal cysts to be easily resected.
