Nasal gliomas are rare benign congenital midline tumors composed of heterotopic neuroglial tissue with the potential for intracranial extension. They are commomly seen in newborns and children but rarely in adults. Preoperative diagnostic imaging is essential to delineate the exact site and extension of tumor and to plan the appropriate surgical approach. Endoscopic surgery is considered appropriate for the removal of intranasal glioma without intracranial extension. We experienced a case of nasophryngeal glioma in a newborn who had been presented with respiratory distress. The tumor was successfully removed by endoscopic surgery. So we report this rare case with the review of literatures.

Background and Objectives:Studies of normal oropharyngeal swallow in children are essential for the analysis of pediatric dysphagia. The purpose of this study is to define the temporal characteristics of the oropharyngeal swallow in children and to compare these data with young adults. Subjects and Method:This investigation evaluated oropharyngeal swallow physiology during swallows of pudding in 16 children (age 3-13) who had no swallowing complaints including velopharyngeal deficits after surgical treatment of cleft palate and submucous cleft, and 16 normal young adults with no swallowing complaints. temporal analysis of swallow in the children was compared with that of similar temporal measures in the 16 young adults (age 21-29). Results:Temporal measures of pharyngeal swallow events in the children revealed significantly shorter pharyngeal response time, shorter duration of tongue base contact to the posterior pharyngeal wall and longer duration of tongue base posterior movement toward the pharyngeal wall as compared with the normal young adult subjects. Conclusion:These differences in the temporal measures of the pharyngeal swallow between children and adults could be the results of differences in the pharyngeal anatomy and the pharyngeal contraction pattern between children and adults. further study of a larger population of normal children is needed.

Background and Objectives:Laryngeal neoplasms such as early glottic cancer can be effectively treated with several methods, namely laser surgery, conservation laryngeal surgery and radiotherapy. Therefore, the preservation of the ability to speak and swallow normally is another important consideration in the selection of therapy for early glottic cancer. The purpose of this study is to compare the functional results of voice and deglutition for early glottic cancer patients treated with surgery or radiation. Subjects and Method:Between January 2002 and September 2004, 17 patients with the early glottic cancer who had undergone radiotherapy (n=6) or surgery (n=11) were retrospectively investigated. All the patients were phonetically analysed using CSL and Fo, Jitter, Shimmer and NHR were evaluated. For aerodynamic test, maximum phonation time (MPT) and mean air flow rate (MFR) were also evaluated. Modified barium swallow (MBS) was performed to evaluate swallowing function. Results: There were no significant difference in all the vocal parameters between radiotherapy group and surgery group. But Shimmer differed significantly between radiotherapy group and laser cordectomy group. In aerodynamic study, MPT was significantly longer in the radiotherapy group than in the surgery group, but no significant difference was observed between the radiotherapy group and laser cordectomy group. MBS showed better results in the surgery group than in the radiotherapy group. Conclusion: Therapeutic modality for patients with early glottic cancer should be chosen in consideration of voice quality and swallowing, and according to multiple parameters of the patients’ conditions.

성대마비 197례에 대한 임상적 고찰

Objectives : Vocal cord paralysis(VCP) is a complex disorder which may result from numerous causes. We reviewed and analyzed the trend of clinical characteristics and causes of VCP in Korean patient. Method : A total 197 patients with VCP who visited St.Mary's hospital from March, 2000 to August, 2006 were reviewed retrospectively. They were analyzed according to sex, age, cause of VCP, position of paralyzed vocal fold, treatment methods. Results : The male and female ratio was 1.6 : 1. The unilateral paralyzed vocal fold was fixed at paramedian position in 84% of the cases. The left vocal fold was paralyzed about 2 1/2 times as much as the right vocal fold. Among the causes of VCP 30.9% of the cases were due to postoperative paralysis, and most of those were developed after lung, mediastinal surgery. laryngeal EMG was performed in 47 patients for determines the prognosis and treatment method. In the unilateral VCP, 90 patients were treated with injection laryngoplasty, 21 patients were performed thyroplasty type I. Conclusion : The causes of VCP include various diseases, so, detection of the primary disease is very important, because many fatal diseases are included among the primary diseases, and late detection can cause serious problems. VCP is not only a disease entity in itself, but can be seen as a sign of an underlying disease.
