Layered Composite Dorsal Onlay Implant for Augmentation Rhinoplasty.

The use of autologous costal cartilage in augmentation rhinoplasty is well-established. However, scenarios where costal cartilage is insufficient or patients are unwilling to undergo additional cartilage harvesting present a challenge. This study introduces a composite dorsal onlay implant, combining silicone and costal cartilage, as an effective solution. Twenty female patients were enrolled in this study. Of these patients, 8 underwent revision surgery who had previous rhinoplasty with costal cartilage graft, and 12 had never previously undergone surgery involving the harvesting of costal cartilage. The implant, created by suturing a silicone base with a costal cartilage overlay, demonstrated low rates of warping and translucency over a mean follow-up of 11.4 months. This method offers a refined nasal appearance, particularly a higher dorsum with reduced translucency for patients with limited costal cartilage availability.
