OBJECTIVES To investigate expressions of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) in squamous cell carcinoma of the tonsil and to correlate expression profiles with clinicopathological characteristics. METHODS Paraffin blocks were obtained from 45 tonsil squamous cell carcinoma (SCC) patients, who underwent(More)
PURPOSE The purpose of this study is to compare the treatment outcomes for locally advanced resectable hypopharyngeal cancer between organ-preserving chemoradiotherapy (CRT) and surgery followed by radiotherapy (SRT). MATERIALS AND METHODS We reviewed 91 patients with stage III/IV hypopharyngeal squamous cell carcinoma treated with radiotherapy (RT). In(More)
BACKGROUND Reconstruction of oropharyngeal defects after resection of oropharyngeal cancer is a significant challenge. The purpose of this study is to introduce reconstruction using a combination of a buccinator myomucosal flap and a buccal fat pad flap after cancer excision and to discuss the associated anatomy, surgical procedure, and clinical(More)
PURPOSE The treatment of a clinically node-positive (cN+) neck is important in the management of oral cavity squamous cell carcinoma (OSCC). However, the extent of neck dissection (ND) remains controversial. The purpose of our study was to evaluate whether level IV or V can be excluded in therapeutic ND for cN+ OSCC patients. MATERIALS AND METHODS We(More)
We analyze metal-clad disk cavities designed for nanolasers in the visible red spectrum with subwavelength device size and mode volume. Metal cladding suppresses radiation loss and supports low order modes with room temperature Q of 200 to 300. Non-degenerate single-mode operation with enhanced spontaneous emission coupling factor β is expected with the TE(More)
We propose a novel design of an all-dielectric optical antenna based on photonic-band-gap confinement. Specifically, we have engineered the photonic-crystal dipole mode to have broad spectral response (Q~70) and well-directed vertical-radiation by introducing a plane mirror below the cavity. Considerably large local electric-field intensity(More)
