The Deep Columellar Approach for Liquid Rhinoplasty - A Case Series of 511 Procedures over 16 years

Overview

Injecting filler into the nose requires a particular approach because complications involving blood vessels are the central concern. This study describes a standardized four step treatment algorithm intended to make the procedure safe, reproducible and effective, entering through the deep columella. Medical records of 511 treatments were reviewed retrospectively for the occurrence and severity of adverse events.

Sections of note

• Retrospective case series of 511 treatments over 16 years.
• The approach is a novel standardized four step treatment algorithm.
• Entry is through the deep columella, the strip of tissue between the nostrils.
• Filler is placed in the deep layers, directly on the bone and on the cartilage covering.
• Blunt cannulas are used rather than sharp needles.
• The authors state the low rate and severity of adverse events correlate with precise, verifiable filler placement in those deep layers.
• The abstract reports no numerical adverse event rate, no patient satisfaction figures and no follow up interval.

What it means for a patient

• A blunt cannula pushes vessels aside rather than piercing them, which is the stated reason for the reduced risk.
• Placing filler on the bone keeps it below the layer where the arteries run.
• Five hundred and eleven treatments is a substantial series, but without a stated adverse event rate the safety claim cannot be checked.
• There is no comparison group treated with needles or a different approach.

Why this paper matters

Vascular complications are the reason nasal filler is considered the highest risk area for injectables, and technique is the main lever available. This series describes a standardized method across a long period. The absence of reported rates limits what it establishes.

Terms

• Liquid rhinoplasty: reshaping the nose with injectable filler instead of surgery.
• Columella: the strip of tissue between the two nostrils.
• Blunt cannula: a flexible blunt tipped tube used to place filler without piercing vessels.
• Supraperiosteal: placed directly on the bone, beneath its covering membrane.
• Supraperichondrial: placed on the membrane covering cartilage.
• Adverse event: any unwanted effect following a procedure.
