A Case of Neuromyelitis Optica Spectrum Disorder of a Patient Who Present for Fungal Sinusitis / 대한이비인후과학회지

Neuromyelitis optica (NMO) is an inflammatory demyelinating disease of the central nervous system, characterized by repeatedly invading the brain, optic nerve, or spinal cord. In 2004, when a disease-specific antibody (aquaporin-4-immunoglobulin G) was discovered in the serum of an optic neuromyelitis patient, it was thought to be a separated disease from multiple sclerosis. Since 2004, however, the concept of the disease has been expanded to include NMO spectrum disorder (NMOSD). We experienced a rare case of NMOSD in a patient who presented with left visual disturbance and underwent endoscopic sinus surgery because of acute fungal sinusitis. We report this case with a review of the literature.

Clinical Outcome Study after External Approach Septoplasty / 대한이비인후과학회지

Background and Objectives@#This study aims to investigate the indications of external approach septoplasty and improvement in subjective symptoms and objective parameters in patients who underwent external approach septoplasty to correct septal deviation with various types of deformities. @*Subjects and Methods@#Thirty-one patients who underwent external approach septoplasty from October 2014 to January 2019 were classified by direction, location, and degree of nasal septal deviation, septal shape and surgical techniques. Through acoustic rhinometry, the minimum cross-sectional area and nasal volume were measured before and after surgery. To evaluate the improvement in symptoms, the Nasal Obstruction Symptom Evaluation (NOSE) survey and nasal congestion visual analogue scale (VAS) were also measured. @*Results@#We found significant correlations between: the direction and degree of nasal septal deviation; the location and degree of nasal septal deviation; septal shape and location of the nasal septal deviation; septal shape and surgical techniques; and the degree of nasal septal deviation and presence of spreader grafts. The NOSE scale following external approach septoplasty improved from 14.7±4.4 to 3.1±3.2 (p<0.001), while the VAS score improved from 7.2±2.3 to 1.2±1.4 (p<0.001). Also, acoustic rhinometry showed that the minimum cross-sectional area and nasal volume at the convex side of nasal cavity significantly increased after surgery. @*Conclusion@#The external approach septoplasty is a surgical technique that is effective not only in improving subjective symptoms, but also in improving objective parameters. External approach septoplasty could be used in case of caudal and/or dorsal nasal septal deviation.

Analysis of Age-Dependent Normative Values of Suppression Video-Head-Impulse Test in Healthy Korean Subjects / 대한평형의학회지

OBJECTIVES: Suppression head impulse paradigm (SHIMP) in video head impulse test is now newly used to test vestibular function. The aim of this study was to analyze normative values of SHIMP for healthy Korean subjects in each decade of life. METHODS: SHIMP and HIMP responses were measured with the video head impulse test in 70 healthy subjects. Vestibulo-ocular reflex gain and anticompensatory saccade were analyzed and compared at each decade of life. RESULTS: All subjects produced anticompensatory saccades in SHIMP. Gain values did not vary significantly with age. Gain values in SHIMP were lower than gain values in HIMP. The gain values of rightward impulse were higher than the gain values of leftward impulse. CONCLUSIONS: Gain values and anticompensatory saccades in SHIMP were consistently equal in each decade of life. Normative values of SHIMP seems largely unaffected by aging.
