PURPOSE Tinnitus is a very common symptom of vestibular schwannoma, present in 45 to 80% of patients. We evaluated changes in tinnitus after translabyrinthine microsurgery (TLM) or gamma knife radiosurgery (GKS). MATERIALS AND METHODS Among 78 patients with vestibular schwannoma who underwent TLM or GKS at Severance Hospital from 2009-2012, 46 patients with pre- or postoperative tinnitus who ...

The purposes of this study were to examine age and gender differences in knee extensor strength, power, and fatigue using open- and closed-chain testing procedures. We tested the hypothesis that specific strength (strength/unit muscle mass) would not differ by age, whereas age differences in specific power and fatigue would remain consequent to blunted maximal contractile velocity. Skeletal mus...

In this paper, The optimized 2D-TLM as been introduced and applied to rectangular waveguides which is widely used. Results obtained by using optimized 2D-TLM were compared with analytic results and shown to be accurate.

B. Wu, P. Qu, J. Yuan, G. X. Shen MRI Lab, Department of Electrical and Electronic Engineering, The University of Hong Kong, Hong Kong INTRODUCTION Minimizing the mutual coupling among array elements is necessary for parallel MRI. Preamplifiers with extremely low input-impedance [1] and capacitive decoupling networks [2, 3] have become the primary techniques for decoupling arbitrarily placed co...

Concentration of a nonfluorescent solution was determined in a 100-nm scale channel using a differential interference contrast thermal lens microscope (DIC-TLM). The DIC-TLM detects a refractive index change induced by sample heating as phase contrast. Concentration measurement was first performed in a nanochannel which is 21 m wide and 500 nm deep. The limit of detection (LOD) was 2.4 M and th...

A three-dimensional transmission-line matrix (TLM) model was developed to simulate microwave-scanning microscopy. A TLM algorithm that allows the simulation of the scanning was developed. Numerical modeling was carried out for frequencies that are commonly used in microwave nondestructive testing (1GHz – 20GHz). Structures with local discontinuities in the electric permittivity are modeled nume...

BACKGROUND Treatment for local glottic cancer recurrences after primary transoral laser microsurgery (TLM) has not been standardized. METHODS In 33 consecutive cases of salvage TLM after laser surgery for early glottic carcinoma failed, we retrospectively considered the potential clinicopathological prognostic factors in univariate statistical setting. RESULTS Patient age <65 years and path...

In an attempt to determine the RF shielding artifacts produced by conducting stents during MRI scanning of patients, a Transmission Line Matrix (TLM) model was developed based on the symmetrical condensed node. This approach allows considerable flexibility including freedom from stability issues and the ability to reconstruct digital signals in the time or frequency domain. To validate the resu...

Current practice standards for the treatment of early to moderately advanced laryngeal and hypopharyngeal cancer demand both achievement of cure and preservation of laryngeal structure and function to the greatest extent possible. The oncologic and functional results of transoral laser microsurgery (TLM) for early glottic cancer appear to be comparable to those of radiotherapy, with a higher ra...

BACKGROUND The purpose of this systematic review and meta-analysis was to assess the oncological and functional outcomes of transoral laser microsurgery (TLM) in radiorecurrent laryngeal cancer. METHODS The review was performed using search strategies including Medline, Embase, Zetoc, conference proceedings, and a manual search. Pooled estimates of local control at 24 months, disease-free sur...
