PURPOSE: To determine the value of magnetic resonance (MR) imaging in predicting resectability head and neck neoplasms around carotid arteries. MATERIALS AND METHODS: Forty-nine patients (28 male 21 female aged 17-79 years; mean, 57.3 years) with masses clinical evidence wall invasion underwent MR imaging. T1-weighted, T2-weighted, gadolinium-enhanced T1-weighted images were analyzed to circumferential involvement 53 arteries by tumor. RESULTS: More than 270 degrees was considered suggestive...

This paper presents and interprets a series of extensive studies the application leading-edge serrations as device for reducing vortex noise radiated from stationary rotating airfoils in low Reynolds number flow. In these studies, variety were attached at selected locations near leading edge airfoils. The levels reduced considerably with attached. An explanation aeroacoustic flow mechanisms involved is given.

To demonstrate the role of transoral laser microsurgery (TLM) in treatment oropharyngeal cancer.A 2-center retrospective case series analysis.Two tertiary care medical centers.The study population comprised 69 patients with previously untreated select T1 to T3, N0 N2 squamous cell carcinoma oropharynx, whom 44 (74%) had no indication for adjuvant RT and 25 (36%) an neck alone but declined radiotherapy. The primary tumor sites were tonsil (n = 28 [41%]), tongue base pharyngeal wall 8 [12%]),...

Analysis included tumor location, staging, reconstructive details,...

Thirty-three patients who had undergone prior surgery and/or radiation therapy for malignant neoplasms of the neck were studied with magnetic resonance (MR) imaging. Twenty-seven these also evaluated computed tomography (CT). Ten healthy posttreatment volunteers, and 23 documented tumor recurrence. MR images better demonstrated normal muscular landmarks, especially in obliterated fat planes. Areas fibrosis or scarring low signal intensity all pulse sequences. However, three patients, high...

Objectives The study goal was to report the oncologic outcomes of transoral laser microsurgery (TLM) in treatment squamous cell carcinoma supraglottic larynx. Study Design and Setting A two‐center prospective case series analysis. Results Thirty‐eight patients underwent TLM for previously untreated larynx between 1997 2005. Pathological T stages were T1 8 (21%), T2 14 (37%), T3 T4 (21%). Twenty‐six (68%) had neck dissections. Thirteen (34%) received adjuvant radiotherapy. mean follow‐up all...

We conducted a retrospective review of patients with unknown primary head and neck cancer who underwent transoral laser microsurgery (TLM)-assisted search for an occult tumor.Fifty-two at single center primaries squamous cell carcinoma (SCC) were treated surgical algorithm.The overall rate tumor identification was 75% (39 52 patients). When selecting those cases in which TLM algorithm lingual tonsillectomy utilized, the detection 86% (31 36). Tumors most commonly found (65.0%) palatine...

As noise from ground transportation vehicles continues to arouse public concern, physical understanding of the various sources becomes essential in seeking means quiet vehicles. Tires are one perdominant on trucks and automobiles. This study analyzes mechanisms by which can be generated interaction a rolling tire with roadway surface. Physical models presented for “air pumping” vibrational aerodynamic mechanisms, then rank-ordered sound-producing capability several classes Results limited...

Objectives To compare reconstructive techniques, operative times, duration of hospitalization, and need for subsequent flap revisions between approaches to lateral skull base defects. Study Design Case series with chart review. Setting Tertiary academic referral center. Subjects Patients (n = 31) undergoing reconstruction composite defects from 2002 2014. Methods Data were analyzed demographics, tumor characteristics, technique, time, complications, outcomes. Results Thirty‐one patients...

Interactive digital signage is increasingly deployed in urban environments, from airports and train stations, to cinemas shopping malls, whilst their integration into public spaces introduces new possibilities multimedia presentation. In this paper, we explore the impact of mid-air haptic feedback on user engagement during gesture-based interactions with posters. To that end, a study seventeen participants was undertaken two independent variables: interactivity (high/low), cues (on/off),...

MR images of six synovial sarcomas the head and neck were evaluated to determine their characteristic sites origin, size, extent, intensity, contrast enhancement. It was hoped that specific characteristics could be defined suggest this entity.A nonmucosal mass is isointense gray matter on T1-weighted well yet heterogeneous, with septations, hemorrhage, cysts, calcification, or multilocularity, should raise suspicion a sarcoma. Because appearance varies other masses may appear similar, no...
