Dorsal Augmentation in Rhinoplasty: A Survey and Review

Overview

Building up the bridge of the nose can be done with the patient's own tissue, donated human tissue or a synthetic implant, and surgeons disagree about which to prefer. The authors surveyed colleagues' practices and searched PubMed for reviews and large series reporting the safety and effectiveness of each material. No numbers from that search are given in the abstract.

Sections of note

• Two parts: a survey of practice among colleagues and a literature review.
• Autologous cartilage grafts remain in widespread use for bridge augmentation and other rhinoplasty steps.
• Irradiated donor rib cartilage is described as a preferred alternative, with low reported complication rates and an abundant supply, particularly useful in revision surgery.
• Silicone implants are prevalent in Asian countries where they are a popular first choice.
• ePTFE has a favourable complication profile in first-time rhinoplasty, but the authors advise caution when using it in revision cases.
• Porous polyethylene carries a higher risk of complications than the other synthetic implants listed.

What it means for a patient

• There is no single correct material. The choice depends on how much height is needed, whether the nose has been operated on before, and how much of the patient's own cartilage is available.
• Using the patient's own cartilage avoids implant rejection but requires a second surgical site.
• Donated irradiated rib avoids that second site and is available in quantity, which matters most in revision surgery.
• This is a narrative review with no pooled complication rates, no survey response numbers and no comparison of outcomes, so it summarises opinion and published series rather than measuring them.

Why this paper matters

Material choice drives both the appearance and the long-term complication risk in augmentation rhinoplasty, and geographic practice differs sharply. The paper maps those differences. What it does not do is quantify the trade-offs in a way that lets one material be ranked against another.

Terms

• Dorsal augmentation: building up the bridge of the nose.
• Autologous graft: tissue taken from the patient's own body.
• Homologous or irradiated rib: donated human cartilage treated with radiation to sterilise it.
• Alloplastic implant: a manufactured implant made from synthetic material.
• ePTFE: expanded polytetrafluoroethylene, a soft porous synthetic implant material.
• Porous polyethylene: a rigid synthetic implant that tissue grows into.
