Abstract
Understanding the nuanced practices and grafting options of dorsal augmentation will
improve outcomes and results in rhinoplasty. To better understand the practices of
dorsal augmentation among our colleagues. To review the current literature regarding
the indications, safety profiles, and outcomes of different materials used in dorsal
augmentation. A PubMed search was performed to capture current articles containing
reviews or large series regarding the safety and efficacy of various grafting materials
used for dorsal augmentation. Of the many options available, autologous cartilage
grafts maintain widespread use for dorsal augmentation and other techniques in rhinoplasty.
Homologous cartilage grafts, namely irradiated rib, are a preferred alternative. Irradiated
costal cartilage has been shown to have low complication rates and is unique in its
abundance of supply, particularly in the revision rhinoplasty. Alloplastic implants,
particularly silicone, are prevalent in Asian countries where they are a popular first-line
choice. ePTFE has a favorable complication profile in primary rhinoplasty; however,
caution is recommended when using ePTFE in revision cases. Porous polyethylene has
a higher risk of associated complications than the other alloplastic implants listed,
and therefore should be considered thoughtfully. Although cartilage is often the preferred
graft for dorsal augmentation, there are many other autogenous, homologous, and alloplastic
materials that have been shown to be safe and effective choices when applied in the
proper setting.
