Neurilemmoma is a benign tumor which arises generally from the Schwann's cells. It is a slowly growing tumor and treated as surgically. We experienced a case of neurilemmoma of the oropharynx in a 28-year-old female who had noticed a gradual swelling of the left side of the oropharynx with swallowing difficulty for 6 months. The tumor was removed successfully intra-orally under the general endotracheal anesthesia and verified pathologically as neurilemmoma.

The purpose of this study was to investigate the changes of the pharyngeal space when the following appliances were inserted: the mandibular advancement appliance (MAA), tongue retaining appliance (TRA), and mandibular advancement-tongue retaining appliance (MATRA). Nine male dental students exhibiting Class I occlusion, normal body mass index (BMI), and no signs and symptoms of snoring were selected for this study. The three kinds of snoring appliances (MAA, TRA and MATRA) were fabricated for each subject. The mandibular advancement of the MAA and MATRA was set at a distance of 5 mm, and the TRA and MATRA were made to hold the tongue in front of the maxillary incisors by 10 to 20 mm. Lateral cephalometric radiographs of the following four states - with no appliance, MAA, TRA, and MATRA - were taken to examine any anatomical changes resulting from the application of the appliances. All four radiographs were traced and analyzed for twenty selected variables related to the pharyngeal space, cranio-cervical posture, and position of the soft palate and hyoid bone. According to the results of this study, there were significant increases in both the upper and lower oropharyngeal spaces when the mandible and tongue were protruded simultaneously, although there was a significant increase only in upper oropharyngeal space when the mandible or tongue was advanced separately. In conclusion, it is suggested that the MATRA may result in more positive effect on the control of snoring and OSA compared to a single use of the MAA or TRA, especially for the patients whose upper airway obstruction occurs in the lower oropharynx.

음성의 생성기전은 폐의 호기에 의하여 성대가 진동하여 원음이 발생하고, 원음이 하인두, 구인두, 비인두, 구강 등의 성도를 통과하면서 공명이 일어나며, 혀와 입술의 운동에 의하여 조음이 일어나서 결국은 음성이 생성되게 된다. 저자는 음성을 생성하는 후두 및 성도의 음성외과학적 구조 및 생리에 대하여 주로 언급하고, 성도에 발생하는 다양한 질환중 음성에 영향을 주는 질환만을 선택하여 간략히 설명하고자 한다. (중략)

구개인두성형술이 코골음과 수면무호흡증에 유용한 수술적 방법으로 널리 이용되고 있으나 코골음과 수면무호흡증의 유발기전이 어리기지 복합적인 원인에 의하므로 구개인두성형술의 적응증을 결정하는데 많은 어려움이 있어, 수술전에 이 방법의 적응이 되는 환자를 보다 정확히 선택함이 중요하므로 많은 사람들에 의하여 주된 병변부위를 검시하는 방법들이 시행되어 왔다. 예를 들면 Mueller maneuver 중 내시경검사, Cephalometrics, polysomnogram, Multiple sleep latency test, CT scan 등의 방법이 환자선택에 이용되었다. 저자들은 비교적 쉽고 경비가 들지 않는 술전 검사법으로 양 후구치봉선(retromolar raphe)을 연결하는 선상에서 구인두궁 (soft palate arch)의 길이를 비교하는 방법을 총 89례에 적용 시행하여 그중 추적관찰이 가능한 46례에서 코골음은 86%, 수면무호흡증은 82%에서 자각적 증상의 개선이 있었기에 구개인두성형술을 시행함에 있어 양 후구치봉선거리와 구인두궁 거리를 비교하는 방법이 간단하고 경제적인 술전 진단방법으로 사료되어 문헌고찰과 함께 보고하는 바이다.

Purpose : Neisseria meningitides is one of the most common causative pathogens of bacteremia and meningitis. Recently protein-conjugated vaccines have been developed and included in the routine vaccination schedule in a few countries. In Korea, carriage rates of N. meningitides among healthy adults have been reported. However, systematic data for childhood carriage rates are not available. This study was performed to evaluate the carriage rates of N. meningitides and the serotype distribution among healthy children attending day care centers. Methods : During the period of January through May 2005, nasopharyngeal swabs and culture were obtained from 904 children attending 13 different day care centers located in Seoul and Gyeonggi Province. The Vitek NHI card was used to identify N. meningitides and the crgA gene was detected via polymerase chain reaction (PCR). Serotype determination was performed by agglutination test using N. meningitides antisera to serotypes A, B, C, D, 29E, W135, X, Y, and Z. PCR for detection of the org2 and saiD gene confirmed serotypes A, B, C, W135, and Y. Results : The mean age among 904 children was 4.5 years; 6.5% (59/904) were children <2 years old, 53.8% (486/904) were 2-5 years old, and 39.7% (359/904) were >5 years old; 52.0% (468/904) were male. N. meningitides was isolated from only 7 children attending 5 different day care centers and the overall carriage rate of N. meningitides was 0.8%. The detected serotypes of N. meningitides were serotype A (n=2), C (n=2), and Y (n=3). Conclusion : The carriage rate of N. meningitides among healthy children attending day care centers was very low in Korea and the detected serotypes were A, C, and Y.
