Peritoneal dialysis. An adjunct to pediatric postcardiotomy fluid management

The need for structural grafting in rhinoplasty arises when the nasal skeletal framework is weakened, malpositioned, or both. This review will be limited to structural grafting of the cartilaginous nasal skeleton. Current techniques will be reviewed and a technique introduced that addresses the common deformity of a superiorly rotated and deprojected nasal tip complex while simultaneously correcting nasal valve collapse. This technique is referred to as the Dynamic Adjustable Rotational Tip (DART) technique. The operative technique of the DART, as well as the basic philosophy regarding the tensile nature of the cartilaginous nasal skeleton will be described.
