OBJECTIVES Limited information is available regarding the characteristics of histiocytic necrotizing lymphadenitis (HNL) in children. This study compares the clinical and laboratory features as well as the immunohistochemical findings of HNL in children with those of adults. STUDY DESIGN Retrospective analysis. METHODS Thirty patients who underwent a(More)
OBJECTIVES We performed a prospective randomized and controlled animal study to investigate the effects of infliximab on experimental otitis media in rats. METHODS Seventy-two Sprague-Dawley rats were randomly allocated to 3 study groups and 1 control group. Infliximab was injected intravenously. Histopathologic changes were determined by(More)
We evaluated the short-term efficacy of Epley, Semont, and sham maneuvers for resolving posterior canal benign paroxysmal positional vertigo (BPPV) in a prospective multicenter randomized double-blind controlled study. Subjects were randomly divided into three groups: Epley (36 patients), Semont (32 patients), and sham (Epley maneuver for the unaffected(More)
We report a patient with an isolated metastasis to the internal auditory canal (IAC) of bronchogenic adenocarcinoma. A 58-yr-old man who had received 6-cycle of chemotherapy under diagnosis of non-small cell lung carcinoma (T4N2M0) two years ago was referred to our department with vertigo, right-sided facial paralysis and right-sided hearing loss. A(More)
The purpose of this study was to establish normative data of laryngotracheal dimensions and shape and to evaluate differences associated with age and sex using three-dimensional (3D) imaging. A total of 120 patients (64 boys and 56 girls) were included. Subjects were divided into four groups: Group 1 (0-2 years), Group 2 (3-7 years), Group 3 (8-13 years),(More)
CONCLUSION The most important predictive factor of facial nerve outcome in surgery for small-sized vestibular schwannoma (VS) is the adhesion between the tumor and the facial nerve. OBJECTIVES To compare the facial nerve outcomes between middle cranial fossa (MCF) and translabyrinthine (TL) approaches, and to analyze the preoperative and intraoperative(More)
CONCLUSION Intratympanic steroid therapy (IT-S) was as effective as systemic steroid therapy (SST) or combined therapy (CT) and could be considered a first-line therapeutic modality for idiopathic sudden sensorineural hearing loss (SSNHL). Due to its known safety and efficacy, IT-S will be particularly suitable for patients with SSNHL who have chronic(More)
BACKGROUND We investigated the relationship between olfactory dysfunction and depressive symptoms and suicidal ideation in South Korea by using data from the 2010-2011 Korea National Health and Nutrition Examination Surveys (KNHANES). METHODS Cross-sectional data of 11,972 adults who completed the KNHANES were analyzed. RESULTS The prevalence of(More)
To radiologically evaluate the anatomic factors that may determine the view field or the accessibility of the posterior tympanotomy into the posterior mesotympanum, a cohort of 30 patients with pneumatic mastoids and 30 patients with unilateral sclerotic mastoids were included. Anatomic relationships were evaluated according to 5 parameters. The reference(More)
OBJECTIVES This study was conducted to compare morphologic and audiologic changes after noise exposure in two different strains of mice (CBA and C57) and to create morphologically proven models of noise-induced hearing loss. METHODS Mice were exposed to white noise at 110-dB sound-pressure level for 60 minutes at the age of 1 month. Hearing thresholds and(More)
