PURPOSE This study reviews our experience with deep neck infections and tries to identify the predisposing factors of life-threatening complications. METHODS A retrospective review was conducted of patients who were diagnosed as having deep neck infections in the Department of Otolaryngology at National Taiwan University Hospital from 1997 to 2002. Their(More)
OBJECTIVES/HYPOTHESIS The purpose of this study was to investigate whether near-continual transtympanic steroid perfusion is more effective than intermittent intratympanic steroid injection as a salvage therapy for idiopathic sudden sensorineural hearing loss. STUDY DESIGN Case control study. METHODS We designed a case-control study consisting of 60(More)
OBJECTIVE The study was to exam if the great auricular point is a dependable landmark for finding the spinal accessory nerve. DESIGN A prospective study from January 2004 to August 2006 in a tertiary medical centre. SETTING A tertiary medical centre, Tzu Chi General Hospital. METHODS In the modified radical neck dissection, the topographic anatomy of(More)
Locoregional recurrence in patients with early stage oral cavity squamous cell carcinoma (ESOSCC) after surgery remains a problem and can affect their survival. We sought to identify new high-risk factors in these patients, who need further adjuvant therapy. We retrospectively reviewed records for 148 patients who underwent surgery for ESOSCC between 2002(More)
OBJECTIVE To present a systematic and practical approach that uses high-resolution computed tomography to derive models of the middle ear for finite element analysis. STUDY DESIGN This prospective study included 31 subjects with normal hearing and no previous otologic disorders. Temporal bone images obtained from 15 right ears and 16 left ears were used(More)
Accumulating evidence reveals that aberrant expression of claudins manifests in various tumors; however, their biological functions are poorly understood. Here, we report on the elevated expression of claudin-1 in nasopharyngeal carcinoma (NPC) cell lines under serum deprivation or fluorouracil (5-FU) treatment. Interestingly, an increase in expression of(More)
Profound idiopathic sudden sensorineural hearing loss is thought to have a poor prognosis, but few studies have focused on this condition. We aimed to assess the impact of patient factors, audiologic parameters, and salvage intratympanic steroid injection therapy on the prognosis of profound idiopathic sudden sensorineural hearing loss. The demographic,(More)
In the present study, the authors compared the long-term risk of nasopharyngeal carcinoma (NPC) of male participants in an NPC multiplex family cohort with that of controls in a community cohort in Taiwan after adjustment for anti-Epstein-Barr virus (EBV) seromarkers and cigarette smoking. A total of 43 incident NPC cases were identified from the 1,019(More)
Latent membrane protein 1 (LMP1) is a pivotal viral oncoprotein that contributes to the carcinogenesis of Epstein-Barr virus (EBV)-associated malignancies, including nasopharyngeal carcinoma (NPC). We investigated the regulation of hypoxia-inducible factor 1-α (HIF-1α) by LMP1. In NPC cells, we found that LMP1 significantly enhanced the HIF-1α mRNA level,(More)
The aim of the present study was to analyze the human mastoid cavity on sound transmission using finite element method. Pressure distributions in the external ear canal and middle ear cavity at different frequencies were demonstrated. Our results showed that, first, blocking the aditus improves middle ear sound transmission in the 1500-to 2500-Hz range and(More)
