The effect of lidocaine on the auditory pathway was studied to evaluate the mechanism of action of lidoncaine by auditory brainstem respose(ABR) in rabbits following intravenous injection, intratympanic bulla application and intrameatal iontophoresis of lidocaine. The changes of ABRs with the similar pattern and the transient delay of wave latencies were observed after administration of lidocaine all animals of different groups. And the prolongation of ABR wave latency was noted in all waves, not any one wave. The results suggest that the principal effect of lidocaine might be the delay of conduction times through the auditory pathway, caused with effect of lidocaine on the central nervous system through the circulatory system and alteration of perilymph lidocaine concentrations in the different routs of administrations of lidocaine

Pneumocele of the paranasal sinus refers to an abnormal expansile cyst-like lesion of an air containing sinus, presumably by obstruction of the sinus ostium due to infection, tumor, trauma or surgery. A one-way valve the nasal cavity and the affected sinus leads to increased antral pressure and sinus expansion after sneezing or nose blowing. The patients usually complain of slowly changing facial contours and dull pain in the affected area. Pneumocele of the paranasal sinus is rare, the frontal sinus is most commonly affected, followed by the ethmoid and the sphenoid sinus. The maxillary sinus is very rare and Noyek and Zizmor reported for first time in 1974. The authors have experience two cases of maxillary sinus pneumocele, so report with review of literatures.

The juvenile nasopharyngeal angiofibroma is a highly vascular, uncommon benign tumor classically ocurring in the vault of the nasopharynx, predominantly in adolescent males. Initial usual symtoms are nasal obstruction, epistaxis and nasal discharge, more commonly on one side. While lacking the ability to metastasize, this tumor is characterized by locally aggresive invasion to the orbit, accessory sinuses, pterygoid and temporal fossae, or the intracranial cavity and so treatment should be offered. Recently the author has experienced a huge juvenile nasopharyngeal angiofibroma in 15 years old male. This tumor was removed surgically with using of the transpalatal approach.

Background and Objectives: Vegetable Foreign bodies (VFB) in the bronchial tree may be complicated by fragmentation, slippage and impaction during the removal with forceps. This study is to evaluate the safety and efficacy for the technique of removing VFB from the bronchial tree in infants and early childhood using Fogarty balloon catheter. Materials and methods : The subjects consisted of 18 infants and early childhood (7-22 months old) with VFB in the bronchial tree from January 1991 through October 1998. The authors first attempted removal of VFB with forceps and if that failed, removed VFB with Fogarty arterial embolectomy catheter under the ventilating bronchoscopy and general anesthesia. Results: We removed 6 VFB with forceps. could not remove anymore, and so removed 12 VFB with Fogarty catheter. In 8 VFB of less than 24 hours, we could remove 6 VFB with forceps and 2 VFB which could not be removed with forceps were removed with Fogarty catheter. In 10 VFB of more than 24 hours, we could not remove with forceps and removed with Fogarty catheter. Conclusions : VFB in the bronchial tree of infants and early childhood can usually be removed with forceps. But we think that Fogarty balloon catheter technique is a easy, safe method for the removal of bronchial VFB of more than 24 hours, fragmentation, impaction, lower bronchus and too round or slippery to remove with forceps in infants and early childhood.

This study developed the research model for confirming the relation of those three factors according to Means-End Chain Model by understanding the chain relation of cosmetics attribute - cosmetic sought benefit - personal values. The experimental results are as follows. First, as a result of the experiment, how the cosmetics attributes influence the cosmetic sought benefits, those who focus on strengthening skin turns out to be seeking for pride, beauty, maintenance of dignity and supplementing weakness, and those who focus more on appropriateness tend to seek for beauty and supplementing weakness. Those who focus on whitening tends to seek for pride, beauty and supplementing weakness, and those who focus on product image seek for pride and supplementing weakness. However, the additionary service attributes are shown to be irrelevant to the cosmetic sought benefits. Second, as result of the experiment that cosmetic sought benefits affect the personal values, those who prefer beauty and supplementing weakness put more emphasis on the values of goal relationship orientation, while those who prefer pride and maintenance of dignity put more emphasis on the values of honor safety orientation. Third, the chain relation of cosmetics attribute - cosmetic sought benefits - personal values is divided into 11 categories. 본 연구는 수단-목적 사슬 이론을 이용하여 화장품 속성, 화장추구편익, 그리고 소비자의 개인가치간의 영향관계를 알아보고자 하였다. 실증적 연구결과는 다음과 같다. 첫째, 화장품 속성 중 피부강화 속성은 화장추구편익 중 자신감, 아름다움, 체면유지, 결점보완 편익에 (+)의 영향을 미치는 것으로 나타났고, 적절성 속성은 아름다움, 결점보완 편익에 (+)의 영향을 미치는 것으로 나타났다. 그리고 미백기능은 자신감, 아름다움, 결점보완 편익에 (+)의 영향을 미치는 것으로 나타났고, 제품이미지 속성은 자신감, 결점보완 편익에 (+)의 영향을 미치는 것으로 나타났다. 그러나 부가서비스는 화장추구편익에 전혀 영향을 미치지 않는 것으로 나타났다. 둘째, 화장추구편익 중 아름다움, 결점보완 편익은 목표관계지향 가치에 (+)의 영향을 미치고, 자신감, 체면유지 편익은 명예안전지향 가치에 (+)의 영향을 미치는 것으로 나타났다. 셋째, 화장품 속성-화장추구편익-개인가치간의 연결관계(사슬) 11개를 도출하였다.

Background & Objectives : Nasal resistance which is halfly responsible for airway resistance is known to be influenced by hypoxia, hypercapnia, exercise, pregnancy, alcohol, ammonia and smoking. Smoking is a common part of our sociocultural environment and we have many a times been introduced to its various adverse effects, which have usually been more focused on lung problems. The purpose of this study is to determine any relationship between smoking and nasal resistance and to evaluate it's effective sites. Materials and Methods : Acoustic rhinometry was performed in 25 smokers and 25 nonsmokers who had no nasal symptoms nor abnormal rhinoscopic findings, and used an acoustic rhinometry to measure the distance from nose-piece to the C-notch, cross sectional area at the C-notch, and volume of the nasal cavity from nose-piece to 7cm. The authors compared the data between the two groups. Results : The cross sectional area at the C-notch was significantly decreased(p<0.05) in smoking group. The distance to the C-notch and the volume of nasal cavity were decreased likely in smoking group but there were no significant difference(p>0.05). Conclusion : Smoking reduced the cross sectional area at the C-notch, so increased the nasal resistance. The underlying mechanisms seems to be decreased nasal mucosal reactivity and congestion of the nasal mucosa. The authors believe there should follow more studies on pathophysiologic mechanisms and the histopathologic changes which involve the effect of smoking on nasal structures.

Tinnitus is noise from ear or head without any external sound stimulation and can cause hearing difficulties, psychogenic disturbances or many difficulties in everyday life. The etiology has yet been discussed and the management is also very difficult. Our study was performed to evaluate the clinical characteristics of idiopathic tinnitus. Three hundred thirty five patients(417 ears) with idiopathic tinnitus were entered into our department's database between Nov. 1995 and Oct. 1997. The patients were fully questioned about their history, and then were physically examined and assessed audiometrically, including pure tone audiogram and tinnitogram. It was found that (1) there was no sexual difference, (2) average age was 48.5 years, (3) there was no laterality, (4) buzzing sound was the most common, (5) average symptom duration was 575.7 days, (6) the most common sensation level was within 5dB, (7) the most common loudness was less than 29dB, and (8) the most common frequency was over 8000Hz.
