OBJECTIVE To describe a technique for creation of a split calvarial bone L-shaped strut that provides dorsal support while increasing tip projection in patients with substantial septal saddle nose deformities from various underlying inflammatory conditions and surgical resection. METHODS Case series and review of the literature. RESULTS Fifteen patients underwent nasal reconstruction at our...

To rapidly track invasive devices within MRI systems, a novel approach using a limited projection reconstruction technique is presented. Our method exploits the difference between images reconstructed from a limited number of projections and serves to depict the tip of a needle during its advancement. This method was implemented on a standard MRI system with a radial fast-spin-echo sequence and...

To capture prey, chameleons ballistically project their tongues as far as 1.5 body lengths with accelerations of up to 500 m s(-2). At the core of a chameleon's tongue is a cylindrical tongue skeleton surrounded by the accelerator muscle. Previously, the cylindrical accelerator muscle was assumed to power tongue projection directly during the actual fast projection of the tongue. However, high-...

Virtual Touch Screen, on a projected area, is a system in which the projection on any ordinary flat surface provides us a graphical work-field for controlling specific kind of operations without any sophisticated touch sensors. Moreover, an ordinary screen area can be transformed into virtual touch screen with the use of a webcam and a projector. The webcam can take the picture of an indicator ...

Rhinoplasty is one of the most complicated aesthetic surgeries. One important factor in nasal profile analysis before surgery is the NTP (Nasal Tip Projection). There has been controversy over defining the best tip projection and due to cultural differences there is a need to find the best formulation for Iranian noses. We selected 50 randomized patients. Lateral nasal views were captured from ...

BACKGROUND Nasal silicone injections have been a common procedure among Asians. However, this can lead to severe complications. Unfortunately, there are limited data available on the distortive characteristics of nasal siliconoma in Asian population. This study aimed provide objective be reference for treatment outcome.
 METHODS cross-sectional was conducted at Cipto Mangunkusumo Hospital ...

Flattening of the nasal tip and shortness of the columella are two of the deformities that remain following successful repair of a bilateral cleft of the lip. Until now, correction has not been possible without producing undesirable scars on the surface of the nose or lip. A three-dimensional Z-plasty on the alar rim achieves columellar lengthening and forward projection of the tip, but it does...

BACKGROUND Proper pre-operative facial analysis that includes a thorough evaluation of both the bony and soft tissue anatomy is paramount to success in performing aesthetic surgery of the face. Ethnic variations in soft tissue profile add an important variable to pre-operative facial analysis. The aim of our study was to determine the role of ethnic variations in soft tissue facial profiles th...

The paper provides analyses for two optical schemes developed for mapping 3-D crack tip fields in ductile materials. The first scheme combines the in-plane moire method with the projection moire method to determine all three displacement components simultaneously. In the second method, we combined onebeam laser speckle photography with the projection moire method to measure 3-D deformation fiel...

T he tripod concept has proved to be a valuable model in understanding nasal tip dynamics. Peter A. Adamson, MD, FRCSC, and colleagues propose the M-Arch Model, which expands the nasal tripod concept by considering the nasal tip tripod in its entirety as an arch. This novel model stresses the importance of the overall length of the medial, intermediate, and lateral crural segments as they form ...
