Abstract
Introduction
Columellar strut graft (CSG) and septal extension graft (SEG) are commonly used in
septorhinoplasty for nasal tip support.
Objective and Hypotheses
We aimed to systematically review and compare CSG and SEG in achieving a desired nasolabial
angle (NLA) and Goode's ratio (GR).
Study Design
Several databases were systematically searched from inception to August 2024. A two-arm
meta-analysis of the pooled means was conducted with a random-effects model. This
review was registered in PROSPERO (CRD42024574909).
Methods
Eligible studies included primary septorhinoplasty patients (≥17 years) receiving
CSG or SEG.
Results
Eight studies met eligibility criteria including 256 CSG and 371 SEG patients. Intergroup
comparison of long-term postoperative NLA favored SEG (p < 0.05) while GR showed no differences. However, SEG patients had significant improvement
in GR postoperatively (p < 0.05), unlike CSG patients.
Conclusion
SEG may provide superior long-term nasal tip rotation and projection stability.
