OBJECTIVE To review the indications, surgical techniques, and results of vertical lobule division (VLD) of the alar cartilages as they relate to the M-Arch Model. DESIGN Retrospective study of patients who underwent VLD of the lower lateral cartilages at a private facial plastic surgery practice in a major university teaching hospital. RESULTS Vertical lobule division decreased projection i...

The yeast mating cell provides a simple paradigm for analyzing mechanisms underlying the generation of surface polarity. Endocytic recycling and slow diffusion on the plasma membrane were shown to facilitate polarized surface distribution of Snc1p (Valdez-Taubas, J., and H.R. Pelham. 2003. Curr. Biol. 13:1636-1640). Here, we found that polarization of Fus1p, a raft-associated type I transmembra...

The cell wall defines cell shape and maintains integrity of fungi and plants. When exposed to mating pheromone, Saccharomyces cerevisiae grows a mating projection and alters in morphology from spherical to shmoo form. Although structural and compositional alterations of the cell wall accompany shape transitions, their impact on cell wall elasticity is unknown. In a combined theoretical and expe...

BACKGROUND Correction of the lower third of the nose is perhaps the most challenging component of performing a rhinoplasty. The tongue-in-groove (TIG) technique provides a method for correcting excess columellar show and maintaining correction of caudal deviation. It is also indicated for controlling nasal tip rotation and projection while preserving the integrity of the lobular cartilaginous c...

The drooping tip deformity is both a bothersome aesthetic feature and functional impairment of the nose. Both static and dynamic factors may affect tip appearance and it seems logical to take into account these factors when planning correction of drooping tip. Many studies have examined this topic, but its treatment remains controversial. In order to make nasal tip surgery successful, it is use...

Suture techniques for reshaping the nasal tip have been in use for many decades. However, the past two decades have been the most influential in the advancement of the procedures commonly used today. This report details the origin of the major tip suture techniques and tracks their evolution through the years. The early techniques in tip rhinoplasty share a basic principle: the sacrifice of lat...

OBJECTIVE To investigate use of the domal stabilization suture as a complementary suture modification technique for refining and securing the nasal tip. METHODS A single permanent or absorbable suture is placed via an open or cartilage delivery approach. The suture is placed along the cephalic borders of the domes at the medial third of the lateral crura bilaterally just posterior to the junc...
