The purpose of this article is to present a modified ultrasonic spreader and a new technique that are used for the retrieval of solid obstructions that can not be bypassed by conventional methods. The technique advocated and the instruments proposed are described. A clinical case is discussed to show the possibilities and limitations of both instrument and method.

A good rhinoplasty dissection is crucial to identify and release the vectoral forces on a deviated septum before correction. Even after completing the dissection, dorsal hump reduction, septoplasty, and osteotomy, there may be persisting septal deviation. A number of techniques have been identified to correct various kinds of deviations that persist after release. Cartilage grafts from the sept...

Super-spreaders are the nodes of a network that can maximize their impacts on other nodes, e.g., in the case of information spreading or virus propagation. Many centrality measures have been proposed to identify such nodes from a given network. However, it has been observed that the identification accuracy based on those measures is not always satisfactory among different types of networks. In ...

OBJECTIVES This study aims to show the placement of extended spreader grafts in reductive septorhinoplasty operations to support the nasal bony vault as well as the middle cartilaginous structures. PATIENTS AND METHODS Thirty-eight patients (16 males, 22 females; mean age 26.4 years; range 18 to 55 years) who underwent septorhinoplasty under general anesthesia via open approach between Januar...

Organic flip chip BGA has been quickly adopted as the mainstream package solution for high speed, high density and high power ASIC and PLD. For these applications, both die and package dimensions are generally large. It is common to see dies over 25 mm and packages of 40 mm or larger. Therefore, warpage is a big challenge. A three-dimensional finite element model was developed to predict the wa...
