41e Patients undergoing rhinoplasty occasionally require a decrease in nasal tip projection. Accomplishing such an objective requires a comprehensive working knowledge of nasal anatomy and function. Maneuvers executed to simply gain exposure during open or closed rhinoplasty can influence final position of the nasal tip. Failure to recognize and account for any alterations in tip support struct...

The authors performed a cadaveric study to evaluate the efficacy of multiple fluoroscopic projections in detecting intra-articular penetration of the screws during femoral neck fracture fixation and also to determine the most suitable radiographic projection. Models of intra-articular penetration in 8 normal proximal femur specimens were created by placing the pins in different quadrants of the...

OBJECTIVE To review the indications for, surgical techniques of, and results of vertical lobule division (VLD) of the alar cartilages. DESIGN Prospective study of patients assigned to undergo variations of VLD of the lower lateral cartilages. SETTING Private facial plastic surgery practice in a major university teaching hospital. PATIENTS Twenty-four patients who underwent variations of V...

The scaling behavior of geometry parameters in three-dimensional dendritic growth is investigated through a detailed measurement of the morphology of pure succinonitrile dendrites grown on the first microgravity flight of the isothermal dendritic growth experiment @M. E. Glicksman, M. B. Koss, and E. A. Winsa, Phys. Rev. Lett. 73, 573 ~1993!#. Measurements are performed of the integral paramete...

In cosmetic rhinoplasty, the patient's satisfaction is most often determined by the quality of the tip surgery, but perfecting a technique for consistently attractive tips can be challenging. As a result, rhinoplasty surgery is now entering a new era of "designer tip" operations, wherein surgeons can employ a combination of open suture tip techniques and tip refinement grafts to achieve consist...

BACKGROUND Lateral crural strut graft has been used in rhinoplasty to correct deformities such as bulbous nasal tip, lateral crus malposition, alar retraction, collapsed external valve, lateral crus concavity, and alar deformity after domal suture. Despite its widespread use, the lateral crural strut graft has not been the subject of studies that show its benefits objectively and statistically....

OBJECTIVE To apply a mathematical model to determine the relative effectiveness of various tip-plasty maneuvers while the lateral crura are in cephalic position compared with orthotopic position. METHODS A Matlab (MathWorks, Natick, Massachusetts) computer program, called the Tip-Plasty Simulator, was developed to model the medial and lateral crura of the tripod concept in order to estimate t...

IMPORTANCE There is no universally accepted quantitative metric that defines the ideal nasal tip rotation and projection. OBJECTIVE To identify the ideal nasal tip projection (NTP) and rotation by using 3 classic NTP methods (Crumley 1, Crumley 2, and Goode). DESIGN, SETTING, AND PARTICIPANTS Lateral facial portraits of normal-appearing white women aged 18 to 25 years were selected from a p...

OBJECTIVE To review the indications for, surgical techniques of, and results of intermediate crural overlay of the alar cartilages in rhinoplasty. DESIGN Prospective study of patients undergoing intermediate crural overlay of the lower lateral cartilages. The setting was a facial plastic surgery private practice. Patients included 10 primary rhinoplasty patients and 1 revision rhinoplasty pat...

OBJECTIVES To describe an alar cartilage-modifying technique aimed at decreasing nasal tip projection in cases with overdeveloped alar cartilages and to compare it with other deprojection techniques used to correct such deformity. DESIGN Selected case series. SETTINGS University and private practice settings in Alexandria, Egypt. PATIENTS Twenty patients presenting for rhinoplasty who had...
