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.
