[BACKGROUND] Since 2006, the authors have explored the option of using septal cartilage as an alar rim graft on the cleft side during primary rhinoplasty to improve nasal symmetry. The aim of this study was to compare the nasal shape with o…

Diced cartilage graft wrapped in Surgicel or fascia has been widely reported in the literature. Pure diced cartilage graft without the use of a "sleeve," on the contrary, is not as commonly reported. This could be due to concerns of graft d…

Pure diced cartilage graft has been the technique of choice for revision rhinoplasty in cleft patients since 2003 at our center. This technique has several advantages over the traditional en bloc cartilage onlay graft including minimal risk…

[BACKGROUND] The purpose of this study was to evaluate progressive changes in surgical techniques and results, aiming for improved nasal shape in primary bilateral cleft rhinoplasty. [METHODS] This is an institutional review board-approved…
