BACKGROUND The 3-dimensionally complex interplay of soft tissue, cartilaginous, and bony elements makes the mastery of nasal anatomy difficult. Conventional methods of learning nasal anatomy exist, but they often involve a steep learning curve. Computerized models and virtual reality applications have been used to facilitate teaching in a number of other complex anatomical regions, such as the ...

This research uses the boundary cutting, spatial-temporal segmentation, block based searching, and gray scale histogram technique to extract the eyes, nose, and mouth images. In this research, gray scale histograms are used to salient the eyes, nose, and mouth features. A spatial-temporal template is designed to slide the eyes, nose, and mouth images to extract the eyes, nose, and mouth image. ...

This article presents an evaluation of the electronic nose technology as an alternative to sensory analysis for assessing the effectiveness of biofilters. An AromaScan A32S electronic nose and a human panel at Duke University’s Taste and Smell Research Lab were used to measure typical volatile compounds from swine confinement buildings. Chemometrics techniques were employed to predict the olfac...

The crooked or twisted nose results from a complex deformity of the bony pyramid, the upper and lower cartilaginous vaults, and the septum and causes functional and aesthetic problems. The forces of scar contracture coupled with long-standing cartilage deformation may make the crooked nose resistant to conventional surgical intervention. The middle vault of the nose may exhibit deformities that...

On examination he had an obvious fracture of the nose with evidence of epistaxis and slight deviation of the nose to the right, together with surgical emphysema between the nose and the eyelids on the right. He took great delight in producing the deformity for the amusement of his comrades. Finger pressure applied to the swollen tissues caused deflation and an audible hiss of air escaping into ...

In response to the report by Nilsson and Ripa of higher rates of Staphylococcus aureus carriage in the throat compared with the rates in the nose (3), Harbarth et al. reported contrary findings for a small number of intensive care unit (ICU) patients (1). They reported a 62% sensitivity of throat swabs for detecting methicillin-resistant Staphylococcus aureus (MRSA) carriage, with only 1 of 13 ...

background: despite the great number of cosmetic rhinoplasties, there are few studies on the improvement of self-concept and patient satisfaction with nose fitness. objectives: this study attempted to examine the variability of self-concept and patient satisfaction with nose fitness before and after cosmetic rhinoplasty through three to six months of follow-up. materials and methods: under a pr...

there have been sparse reports in literature of avulsion and degloving injuries of individual areas of face like the nose, eyelids, ear and even mandible. hemi-facial degloving is extremely rare. we present a case of post-assault degloving of the nose, part of forehead with anterior wall of frontal sinus, entire upper and lower eyelids and the cheek. proper planning and staging of the surgical ...

The research and development of new electronic-nose applications in the biomedical field has accelerated at a phenomenal rate over the past 25 years. Many innovative e-nose technologies have provided solutions and applications to a wide variety of complex biomedical and healthcare problems. The purposes of this review are to present a comprehensive analysis of past and recent biomedical researc...

Purpose The aim of this study was to compare the long-term outcomes of total laparoscopic surgery with Natural Orifice Specimen Extraction (NOSE) with those for conventional laparoscopy (CL)-assisted surgery for treating rectal cancers. Methods We reviewed the prospectively collected records of 844 patients (163 NOSE and 681 CL) who underwent curative surgery for mid- or upper rectal cancers ...
