PURPOSE Hearing loss can lead to a number of disabilities and can reduce quality of life. Noise-induced hearing losses have become more common among adolescents due to increased exposure to personal music players. We, therefore, investigated the use of personal music player among Korean adolescents and the relationship between hearing threshold and usage(More)
OBJECTIVES Some patients with dizziness show high comorbidity with psychiatric disorders. However, the association of vestibular deficit with psychological symptoms remains controversial. Thus, we investigated psychological distress (depression and anxiety) in patients with vestibular disease and examined factors modifying the development of psychological(More)
CONCLUSIONS Bacterial predominance and antibiotic sensitivity have changed over time, making continuous and periodic surveillance necessary in guiding appropriate antibacterial therapy. OBJECTIVES With the development and widespread use of antibiotics, the types of pathogenic microorganisms and their resistance to antibiotics have changed. Knowledge of(More)
PURPOSE We have investigated vestibular evoked myogenic potentials (VEMPs) as a function of age and the involvement of each of the 3 semicircular canals in patients with benign paroxysmal positional vertigo (BPPV). MATERIALS AND METHODS We performed prospective assessment from January 2005 to September 2006. Vestibular evoked myogenic potential was(More)
OBJECTIVE Intratympanic (IT) dexamethasone offers a good method for avoiding systemic side effects in patients with sudden idiopathic sensorineural hearing loss (ISSHL). However, in most studies, IT was used as a salvage treatment for patients whose hearing failed to improve with the initial systemic treatment, or as an addition to conventional oral steroid(More)
Daewoo Shipbuilding Company, one of the largest shipbuilders in the world, had difficulties with planning and scheduling its production process. To solve the problems, Korea Advanced Institute of Science and Technology (KAIST) and Daewoo have been jointly performing the DAS (DAewoo Shipbuilding Scheduling) Project for three years from 1991 to 1993.

OBJECTIVE Although the literature includes many reports of the causes, pathogenesis, diagnostic criteria, treatment, and prognostic factors of sudden sensorineural hearing loss (SSNHL), few studies have examined recurrent SSNHL. This prompted us to investigate recurrent SSNHL. STUDY DESIGN Retrospective study of the hearing results of patients with(More)
CONCLUSION We interpreted VEMP findings in patients with the three major peripheral vertigo diseases, taking age-related changes into consideration. We found different abnormal VEMP rates among the three diseases, as well as differences in the proportion of parameters that were abnormal, according to the type of disease. OBJECTIVES Vestibular neuritis,(More)
OBJECTIVES Although many studies have assessed sudden deafness in adults, sudden deafness has not been evaluated in children. We therefore evaluated the differences in sudden deafness between children and adults. METHODS We compared clinical manifestations, including gender, audiogram pattern of initial hearing loss, and recovery rate after treatment in(More)
BACKGROUND Endoscopic reduction has become common for reducing medial orbital wall fractures because of its various advantages. Nevertheless, there is no standard method of nasal packing to support the orbital contents to maintain the reduction. We evaluated the outcomes of endoscopic reduction of medial orbital wall fractures using the rolled Silastic(More)
