Background:
Insufficient support of the nasal mid-vault during rhinoplasty can cause significant complications. Accordingly, surgeons have recently paid much more attention to the preservation of nasal patency. The spreader graft is the gold standard technique for the reconstruction of nasal mid-vault.
Objectives:
The objective of this study was to compare the spreader graft and spreader flap in terms of aesthetic and functional outcomes.
Methods:
An inclusive search was performed with PubMed/Medline, Google Scholar, and Cochrane Library databases up to April 2021. Multiple aesthetic and functional factors, including dorsal aesthetic lines restoration, satisfaction rate, internal nasal valve angle improvement, nasal obstruction symptom evaluation scale, and active anterior rhinomanometry were evaluated. Also, a meta-analysis was performed on the included articles that provided adequate data for mentioned factors.
Results:
After excluding papers that did not conform with the selection criteria, 10 articles with a total sample size of 567 cases with a mean age of 27.7 years (range, 18-65 years) were finally included. Analysis of the data revealed no statistically significant difference between the spreader graft and spreader flap techniques in terms of dorsal aesthetic lines restoration, internal nasal valve angle improvement, nasal obstruction symptom evaluation scale, and anterior rhinomanometry.
Conclusions:
However, in terms of satisfaction rate, the analyzes indicated that spreader graft has significantly superior aesthetic outcomes. Generally, in case of appropriately selected patients, there is no statistically significant difference between spreader graft and spreader flap techniques in terms of aesthetic and functional outcomes.
