An Economical Approach to Ethnic Asian Rhinoplasty

Overview

Asian patients seeking augmentation rhinoplasty often have too little septal cartilage for standard techniques. The authors describe a method designed to economise that cartilage by transmitting forces across the bridge instead of relying on strong support at the front lower edge of the septum, so lengthening and tip projection can be prioritised.

Sections of note

• 104 Taiwanese patients had rhinoplasty with dorsal augmentation and lengthening using the modified technique, between 2012 and 2014.
• The septal extension graft is positioned exaggeratedly forward. Paired extended spreader grafts remove the need for a columellar strut.
• Soft tissue changes were analysed by photogrammetry, including a new measure the authors call the roundness index.
• Tip projection, dorsal length, nasal height, alar length and columellar length all increased significantly after a mean 5.5 months of follow-up.
• Nasal tip angle, roundness, columella-labial angle and nostril axis inclination all decreased.
• Change size did not differ between patients followed less than and more than six months. The most common complication was new or persistent tip deviation in five cases (5 percent).

What it means for a patient

• The technique is designed for noses with limited septal cartilage, using a dorsal implant for the bridge and spreading the load rather than adding more grafts.
• Measured changes held between the shorter and longer follow-up groups, suggesting the result was not simply settling swelling.
• One patient in twenty had a tip that was or stayed off centre, which is the main reported complication.
• Single centre, no comparison technique, mean follow-up only 5.5 months, and outcomes were measured from photographs rather than reported by patients.

Why this paper matters

Cartilage scarcity is the practical constraint in Asian augmentation rhinoplasty, and most solutions either harvest rib or add a synthetic implant. Redistributing structural load is a third approach. Whether the result holds beyond a year, and how it compares with conventional septal extension, is not addressed.

Terms

• Tongue-in-groove: fixing the tip cartilages onto the lower edge of the septum to set tip position.
• Septal extension graft: cartilage attached to the septum to lengthen the nose and set tip position.
• Spreader graft: a narrow cartilage strip placed alongside the septum, extended here for support.
• Columellar strut: a cartilage support placed between the nostrils to hold the tip.
• Photogrammetry: taking measurements from standardised photographs.
