We often observe that uptake of tracer is not detected in the primary cancer focus in patients with histologically proven papillary thyroid carcinoma (PTC) on preoperative 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET/CT). Therefore, we analyzed the clinical and pathologic variables affecting false-negative findings in(More)
OBJECTIVE To describe a case of the atlantoaxial rotary subluxation (AARS) after tympanoplasty and discuss its mechanism and management. PATIENTS A 10-year-old boy. INTERVENTIONS Cervical spine plain radiography followed by cervical traction. MAIN OUTCOME MEASURES Range of motion and radiologic follow-up. RESULTS The patient showed painful(More)
The objectives of the study were to analyze the clinical features of inverted papillomas (IP) associated with malignancy and to evaluate the correlation of tumor stage, survival and histolologic features. We conducted a retrospective review of 18 IP associated with malignancy patients. In addition, we compared histopathologic characteristics (tumor(More)
OBJECTIVE The purpose of this study was to evaluate the effect of furanone as a quorum sensing inhibitor with an antibiotic agent on experimentally induced Pseudomonas aeruginosa biofilm formation in an in vitro model. MATERIALS AND METHODS Bacterial cultures on agar plates and induction of biofilm formations were done in four different conditions; P.(More)
OBJECTIVE The aim of this study was to understand the prevalence and molecular genetic etiology of incomplete partition type III (IP type III) anomaly in Koreans. We also attempted to verify the prevalence of genomic deletions in the DFNX2 locus and to look for association between inheritance patterns and mutation type in East Asian IP type III subjects.

OBJECTIVE/HYPOTHESIS The purpose of the study was to investigate the effect of intravenous adipose tissue-derived stem cell (ADSC) transplantation on olfactory epithelium regeneration following transection of the olfactory nerve in rats. STUDY DESIGN This was a experimental study using primary cultures of mesenchymal stem cells derived from animal adipose(More)
The aim of this study was to investigate the effects of intracochlear bleeding during cochleostomy on cochlear inflammatory response and residual hearing in a guinea pig animal model. Auditory brainstem response threshold shifts were greater in blood injected ears (p<0.05). Interleukin-1β, interleukin-10, tumor necrosis factor-α and nitric oxide synthase 2,(More)
Sialectasis of Stensen’s duct is an uncommon condition of the salivary gland featuring dilation of the parotid duct. Various surgical and non-surgical treatment modalities have been reported as treatment for Stensen’s duct stenosis. In this report, a rare case of sialectasis with fusiform dilatation of the parotid duct is presented, which was corrected by a(More)
Acute unilateral vestibular loss presents as ocular torsion (OT) and caloric unilateral weakness (UW). However, the amount of OT is frequently dissociated from UW depending on when the examination was performed and the extent and cause of the vestibular lesion. This study evaluated the relationship between OT and UW in peripheral vestibular diseases,(More)
OBJECTIVES The purpose of this study was to investigate the clinical features, radiologic findings, and treatment outcomes in patients of facial nerve paralysis with chronic ear infections. And we also aimed to evaluate for radiologic sensitivities on facial canal, labyrinth and cranial fossa dehiscences in middle ear cholesteatomas. METHODS A total of 13(More)
