Backgrounds: The columellar strut graft (CSG) can help to correct nasal tip (NT) deformities in rhinoplasty. The value of using the CSG technique as a routine procedure in rhinoplasty is still being debated. The reason for this ambivalence is the increased rotation effect of a CSG on the nasal tip. In this article, ’b’ (small letter ‘B’) shaped columellar strut graft was prepared differently from the traditional CSG, and two different designs of CSGs were compared in terms of nasolabial angles.
Materials-Methods: A total of 99 patients who were operated on using CSG between September 2018 and March 2020 were included in this study. We analyzed preoperative and postoperative lateral views of photographs and case histories of 99 patients. Traditional shape and b-shaped CSGs were used for 33 (33.3%) and 66 (66.6%) of total patients, respectively. The groups of traditional shape and b-shaped CSGs were compared with statistical analysis.
Results: When postoperative nasolabial angles were evaluated, it was found that 36.4% and 7.6% of the nasolabial angles were above the optimal range in the traditional strut graft group and b-shaped CSG group, respectively. Wide-nasolabial-angles were observed more common in cases with traditional strut graft than in cases with b-shaped CSG. The b-shaped CSG provided gain optimal projection without extended rotation. The difference between the two groups was statistically significant (p= 0.00).
Conclusion: The overall conclusion derived from this research is that an optimally shaped columella can be obtained by using a b-shaped CSG without over-rotation of the nasal tip.
