Use of Fillers in Rhinoplasty

Overview

Surgical rhinoplasty is described as one of the most common cosmetic procedures among Asian patients, but it carries recovery time, high cost and a steep learning curve, and most of its complications relate to implants. The author presents filler injection as a safer and less invasive alternative, with detailed anatomy as the requirement for using it safely.

Sections of note

• The article is a review chapter, not a study of patients.
• Stated limitations of surgery are downtime, high cost and a steep learning curve, with most complications implant related.
• Good knowledge of nasal anatomy is described as essential for filler rhinoplasty.
• Knowing the nerves, blood supply and injection plane is what allows complications to be avoided.
• The nose has several tissue planes. The deep fatty layer is recommended for injection because it is wide, loose, and contains fewer important nerves and vessels.
• Botulinum toxin can also be used for non-invasive nasal reshaping. No patient numbers, complication rates or outcome data appear in the abstract.

What it means for a patient

• Filler can change nasal shape without surgery, with no recovery time, but the change is not permanent.
• The depth at which filler is placed is the main determinant of safety, because injecting into or near a blood vessel in the nose can have serious consequences.
• This makes who performs the injection, and their knowledge of nasal anatomy, more important than the product used.
• The abstract reports no cases, complication rates or duration of effect, so nothing here quantifies either the benefit or the risk.

Why this paper matters

Non-surgical rhinoplasty expanded quickly with limited safety literature, and the nose is among the higher-risk facial areas for filler because of how its blood supply runs. Naming a preferred anatomical plane is a concrete safety recommendation. How long results last, and how often complications occur, is not addressed.

Terms

• Filler: an injectable gel used to add volume and change contour.
• Injection plane: the tissue layer at which filler is placed.
• Deep fatty layer: a loose layer of fat beneath the nasal skin, above the framework.
• Neurovascular structures: nerves and blood vessels.
• Botulinum toxin: an injectable drug that temporarily weakens targeted muscles.
• Non-invasive: performed without cutting into the body.
