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)
Chondroblastoma is a rare benign bone tumor. It commonly affects the epiphysis of long bones during the second and third decades of life. Chondroblastoma of the temporal bone is extremely rare. We reviewed five cases of chondroblastoma arising in the temporal bone. Four cases were female and one was male. The ages ranged from 41 to 60 years (mean, 53.6(More)
The role of flocculus in vestibular compensation is still a controversial issue. Calbindin regulates intracellular signaling and has been reported to be a reliable marker of Purkinje cell. Expression of calbindin in flocculus was examined using immunohistochemistry following unilateral labyrinthectomy (UL) in rats. Both the staining intensity and number of(More)
Metastatic temporal bone tumors are rare diseases and they are usually clinically asymptomatic, so it is difficult to diagnose them. Breasts are the most common sites of temporal bone metastasis. Tumors of lung, kidney, gastrointestinal tract, prostate gland, larynx and thyroid gland are the other sites. The pathogenesis of the temporal bone is most(More)
Endometriosis of a surgical scar is rare and occurs mainly when a hysterectomy or Cesarean section was performed. We describe a 54-year-old woman with a large suprapubic mass as a definite case of a endomerioid carcinoma developing within the scar endometriosis following Cesarean section. Scar endometriosis, as well as endometriosis at other sites, can turn(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)
Congenital cholesteatomas of mastoid origin are extremely rare. We reported one in 2007 and experienced an additional case. A male presented with a 5-month history of right-sided ear discharge. Computed tomography of the temporal bone showed a soft tissue density occupying the mastoid tip. At surgery, the cholesteatoma sac was completely isolated from the(More)
OBJECTIVES Otitis media (OM) is an infectious disease that affects all age brackets. Aural discharge is a typical symptom, occurring in all subtypes of OM. We have compared the identity and antibiotic sensitivity of bacteria isolated from aural discharges of adults and children with various types of OM, including acute OM (AOM), OM with effusion (OME),(More)
OBJECTIVES By assessing unilateral utricular function at the acute and subacute stages, we sought to determine the ability of the subjective visual vertical (SVV) during eccentric rotation (dynamic SVV) in detecting latent abnormality of otolith dysfunction in unilateral vestibular neuritis. In addition, we compared the validity of the dynamic SVV with(More)
OBJECTIVE There have been only a few reports of subjective visual vertical (SVV) in patients with benign paroxysmal positional vertigo (BPPV), and each showed slightly different results. SVV measurement during eccentric rotation that stimulated only 1 labyrinth was known to show a considerable improvement in comparison with conventional SVV as a clinical(More)
