Injection Rhinoplasty Using Filler

Moon HJ.

What this paper says

A technique review of nasal filler injection, specifying the deep fatty layer as the correct plane to avoid blocking a blood vessel, and giving an injection order of radix, rhinion, tip, then supratip.

Overview

Filler injection is used as an alternative to surgery for reshaping the nose, with fewer side effects and shorter recovery. The article describes the layered anatomy of the external nose and gives practical rules for where and in what order to inject, and how to avoid asymmetry.

Sections of note

Rhinoplasty is described as commonly performed in Asia, with filler preferred for fewer side effects and shorter downtime.
The tissue between the skin and the bone or cartilage of the external nose is described as consisting of 4 layers.
Injection should be into the deep fatty layer to prevent vascular compromise and embolization.
The usual injection order is radix, rhinion, tip, then the supratip area.
To minimize asymmetry, the midline should always be marked on the bridge and the procedure performed without deviating from it.
The abstract gives no patient numbers, filler types, volumes, complication rates, duration of effect, or follow-up.

What it means for a patient

The depth of injection is the main safety control, because filler entering a blood vessel can block it.
Marking the midline before injecting is a basic step against ending up asymmetric.
The nose is treated in a set sequence of four areas rather than freely.
This is a technique review with no data, so it does not report how often complications occur or how long results last.

Why this paper matters

Nasal filler is widely marketed as a low-risk alternative to surgery, while the nose carries the highest vascular risk of any facial injection site. Setting out the plane and sequence is the practical safety content. The abstract quantifies neither the risk nor the benefit.

Terms

Injection rhinoplasty: Reshaping the nose with injectable filler instead of surgery.
Deep fatty layer: The tissue layer just above the covering of the cartilage and bone.
Embolization: Material entering and blocking a blood vessel.
Radix: The root of the nose, the deepest point between the eyes.
Rhinion: The point where the nasal bone meets the cartilage on the bridge.
Supratip: The area just above the nasal tip.
