Background: The aim of the study was to assess, whether there is a difference in aesthetic and functional patient satisfaction between closed nasal reductions with intraoperative Cone-Beam Computed Tomography (CBCT) without using medical imaging. Methods: A monocentric, retrospective cohort 43 patients (20 treated CBCT 23 imaging) conducted. Subjective postoperative aspects nose were assessed. ...

A method is presented for calculating the aerodynamic heating and shear stresses at the wall for tangent ogive' noses that are slender enough to maintain an attached nose shock through that. portion of flight duringwhich heat transfer from' the botundary layer to the wall is significant. The lower entropy of the attached nose shock combined with the inclusion of the streamwise pressure gradient...

The stability and receptivity of three-dimensional supersonic boundary layers over a 7 ° sharp tipped straight cone at an angle of attack of 4.2° is numerically investigated at a free stream Mach number of 3.5 and at two high Reynolds numbers, 0.25 and 0.50*10 6/inch. The generation and evolution of stationary crossflow vortices are also investigated by performing simulations with three-dimensi...

OBJECTIVES Surgical correction of skeletal maxillary retroposition is often associated with changes in the morphology of the nose. Unwanted alar flaring of the nose is observed in many cases. The aim of the present study was therefore to investigate the influence of surgical advancement of the maxilla on changes in the soft-tissue morphology of the nose. Having a coefficient that allows predict...

A new and fast registration algorithm has been proposed to update the tool-path of a deburring robot, intended to machining composite workpieces under gravity and clamping deformations. A Subdivision Iterative Closest Point algorithm, which considers different parts of the contour with respect to curvature, allows to obtain far better results than classical methods, without complicated assumpti...

Most models of radiative jets have been computed for the special case of a top hat initial cross section. This paper discusses the dynamics of both leading and internal working surfaces in jets with more general initial cross sections, based on both an analytic, “thin shell” model, and on a full numerical simulation. We find that a non-top hat cross section for the jet ram pressure first leads ...

A 27-year-old man presented an anterior open bite relapse. He had low tongue posture positioned anteriorly at rest and during swallowing and reported chronic difficulty in nose breathing. Head cone-beam computed tomography revealed nasal septum deviation, right turbinate hypertrophy, and left maxillary sinus congestion, which were thought to contribute to the breathing problem, encourage the im...

Trichorhinophalangeal syndrome (TRPS) is a rare genetic disorder with typical craniofacial and skeletal abnormalities. Three main subtypes have been described. All variations of the condition affect the hair (tricho), nose (rhino) and fingers (phalangeal). The diagnosis is usually made through clinical examination augmented by hand radiographs that reveal characteristic cone-shaped epiphyses Sp...

The tricho-rhino-phalangeal syndrome (TRPS) type I is a rare genetic disorder related to the TRPS1 gene mutation in chromosome 8, characterized by craniofacial abnormalities and disturbances in formation and maturation of bone matrix. The hallmarks are sparse and brittle hair, tendency to premature baldness, bulbous nose called pear-shaped, long and flat filter and low ear implantation. The mos...
