OBJECTIVES Cisplatin, a widely used chemotherapeutic agent, has serious side effects, including nephrotoxicity and ototoxicity. Minocycline is a semisynthetic second-generation tetracycline that exerts anti-inflammatory and neuroprotective effects. The purpose of this study was to elucidate the protective effect of minocycline against cisplatin-induced(More)
Tubular apocrine adenoma (TAA) is a very rare sweat gland tumour. Comprehensive review of the literature reveals that TAA in the external auditory canal (EAC) has not yet been reported. We report a case of TAA in the EAC, together with characteristic histopathological findings.
OBJECTIVES Intratympanic steroids are being increasingly used in the treatment of sudden sensorineural hearing loss (SSNHL) after the failure of systemic therapy. This study evaluated the efficacy of administering intratympanic dexamethasone (ITD) as a salvage treatment for severe to profound SSNHL. METHODS We reviewed the medical records of patients who(More)
Saposin B (Sap B) is an essential activator protein for arylsulfatase A in the hydrolysis of sulfatide, a lipid component of myelin. To study Sap B's role in hearing and balance, a Sap B-deficient (B(-/-)) mouse was evaluated. At both light and electron microscopy (EM) levels, inclusion body accumulation was seen in satellite cells surrounding spiral(More)
BACKGROUND AND OBJECTIVES Sudden sensorineural hearing loss (SSNHL) is commonly defined as a loss of at least 30 dB in three contiguous frequencies occurring within 3 days. Systemic steroid administration has become the most widely accepted treatment option for SSNHL. Since viral infection and vascular compromise are considered specific causes of SSNHL,(More)
BACKGROUND AND OBJECTIVES The most common complication of tympanostomy tube (T-tube) insertion is the development of postoperative otorrhea. Post-tympanostomy tube otorrhea (PTTO) is defined as active drainage through an existing T-tube. Many surgeons routinely use topical antibiotics as prophylaxis against early PTTO. Mupirocin calcium ointment is a(More)
A solitary fibrous tumor (SFT) is an extremely rare, distinct otological soft-tissue tumor. Only two such tumors in the external auditory canal have been reported. A SFT related to hemangiopericytomas (HPC), which commonly arise in the central nervous system. HPCs act malignant in many cases, while SFTs at other sites are mainly benign. A 25-year-old female(More)
