Current Practices in Dorsal Augmentation Rhinoplasty

Overview

Dorsal augmentation rhinoplasty addresses both appearance and breathing problems caused by a low nasal bridge. It can be done with a variety of techniques and grafting materials, each with distinct advantages and disadvantages. The article provides a detailed overview of the available materials, their uses, risks and benefits.

Sections of note

• Review article; the abstract reports no patient numbers, no rates and no follow up.
• The patient's own graft materials include septal cartilage, ear cartilage and rib cartilage.
• Those donor sites can provide cartilage either as a single solid block or diced.
• Bone may be used when strong structural stability is required.
• Soft tissue may be used to fill mild to moderate defects.
• Donor grafts, including irradiated and non irradiated rib, and processed donor skin are alternatives with similar advantages and no need for a second surgical site.
• Artificial implants may be used successfully provided both patient and surgeon understand the associated risks.
• The stated conclusion is that surgeons should be familiar with the full range of materials and their risks and uses.

What it means for a patient

• The main trade off is between using the patient's own tissue, which requires a second incision, and donor or artificial material, which does not.
• Bone is reserved for cases needing maximum rigidity; soft tissue only for minor deficiencies.
• Artificial implants are presented as workable but conditional on the patient understanding their specific risks.
• No rates, comparisons or outcome data are reported in the abstract.

Why this paper matters

Material choice determines the durability of a bridge augmentation and whether the patient carries a second scar, and there is no consensus on which is best. This review lays out the options side by side. It does not rank them on measured outcomes.

Terms

• Dorsal augmentation: raising the height of the nasal bridge.
• Autologous graft: tissue taken from the patient's own body.
• Homologous graft: tissue from a deceased donor, processed for surgical use.
• Acellular dermal matrix: processed donor skin with the cells removed.
• Alloplastic implant: an artificial, manufactured implant material.
• En bloc: as a single solid piece rather than in fragments.
