Abstract Facial defects not only impact on the function and quality of life but also affect the psychological well-being and social behavior of patients. A nasal prosthesis can re-establish the esthetics and anatomical contour in patients with mid-facial defects, often more effectively than surgical reconstruction. For successful results, many factors such as retention, texture, color match ...

The fibula free tissue transplant has been used in mandibular reconstruction for several decades. Various techniques exist to shape and contour the fibula to restore continuity to the segmental mandible defect. Recently, virtual surgical planning has introduced the ability to use cutting guides to contour and create osteotomies for fibula free tissue reconstruction of the mandible. In this arti...

Aim: Computerized tomography (CT) examination of temporal bone is a routine procedure in the diseases of the middle ear. The aim of this study is to establish the efficacy of CT in the diagnosis of the complications due to inflammatory pathologies of middle ear. Method: Patients with suspected middle ear pathology were undergone temporal CT examination between August 2006June 2008. 56 patients ...

This work is devoted to studying a direct and inverse scattering problem for magnetoelastic layer having defect, in the frame of electromagnetic theory. In terms displacement field over defect's contour, coupled system boundary integral equations formulated, magnetically permeable impermeable defects. To identify position size an efficient numerical algorithm developed by using quasi-Newton ite...

Partial differential equation (PDE)–based image processing has played a substantial role and become more popular in the recent years. In the application of weld defect detection, the PDE models can be applied for image smoothing and segmentation. In this study, anisotropic diffusion proposed by Perona Malik known as Perona Malik Anisotropic Diffusion (PMAD) model is used as a denoising process ...

A welded structure must be inspected to guarantee that the weld quality meets the design requirements to assure safety and reliability. However, X-ray image analyses and defect recognition with the computer vision techniques are very complex. Most difficulties lie in finding the small, irregular defects in poor contrast images which requires pre processing to image, extract, and classify featur...

A subcutaneous pedicle ulnar flap used to cover a skin defect around the wrist is reported. Unlike the standard ulnar flap, which is isolated around the dorsal branch of the ulnar artery and its associated veins, this flap is based on the ascending branch of the dorsal branch of the ulnar artery more proximally to obtain a longer vascular pedicle. A subcutaneous pedicle flap that contained the ...
