The objective of this study was to evaluate whether elective neck dissection could improve regional control or survival time in clinical stage I squamous cell carcinoma of the oral tongue (OTSCC). This was a retrospective study of patients with surgical treatment between January 1991 and December 2003. A total of 131 patients were included in the study, and(More)
PURPOSE OF REVIEW Primary salivary gland-type nasopharyngeal carcinoma (PSGT-NPC) is an uncommon malignancy with aggressive behavior and poor prognosis. Its optimal treatment policy remains debated, even though recent evidence provides support for a multimodality approach. The aim of this study was to summarize the optimal management approaches and(More)
BACKGROUND Primary salivary gland type nasopharyngeal carcinoma (SNPC) is a rare malignancy with diverse clinical behavior and different prognoses. Previous studies have reported on limited patient populations, and few long-term studies have outlined outcomes and prognostic factors. Furthermore, controversy exists as to the treatment policy of SNPC. The aim(More)
INTRODUCTION Although anaplastic thyroid carcinoma (ATC) is rare, it is one of the most aggressive human cancers. The optimal multimodal therapy policy of ATC is still debated, and a standardized treatment strategy remains to be established. This study aimed to evaluate the management aspect and prognosis of ATC. MATERIALS AND METHODS The data were(More)
Numerous studies on carcinoma have revealed that the expression level of HOXB7 in cancerous tissues was significantly higher than that in noncancerous tissues. Elevated expression of HOXB7 is associated with the susceptibility to lymph node metastasis and distant metastasis in various tumors. In this study, a meta-analysis was performed to involve majority(More)
OBJECTIVE To reconstruct a finite element model of human middle ear and measure characteristic dimensions of this model and calculate the mass properties of the ossicles. METHODS The proposed method starts with the histologic section preparation of human temporal bone. Through tracing outlines of the middle ear components on the sections in AutoCAD2005, a(More)
OBJECTIVE To design a tool for evaluating the sound transmission function of ossicular prosthesis and explore the impacts of ossicular prosthesis bead area and the effects of the mass of ossicular prosthesis on the sound transmission function in mechanical middle ear model. METHODS Two latex membranes were used to represent the tympanic membrane and oval(More)
