Comparison of Columellar Strut Graft (CSG) and Septal Extension Graft (SEG) Methods of Nasal Tip Plasty in Changes of Nasal Tip Position

Abstract

Objective: The aim of this study is to compare the methods of columellar strut graft and septal extension grafts innasal tip plastic surgery in changing the position of the nasal tip. 

Methods: In this cross-sectional study, information and parameters recorded in the files of 50 patients applying for rhinoplasty surgery who were operated on the personal office of Dr. Ali Shabani were examined, 25 of whom underwent columella strut graft and 25 of whom underwent septal extension graft and were also examined or changes in the position of the nasal  tip. Patients were photographed before, during, and six months after rhinoplasty, and the position of the nasal tip were compared using Chi-square, repeated measurements, paired samples t-test, and independent t-test in the two methods. A significant level of 0.05 was considered.

Findings: Changes in the nasolabial angle over time between the SEG and CSG methods were not significant (P=0.197). Changes in the upper part of the nasolabial angle over time were significantly higher in the SEG method than in the CSG method (P=0.024). Changes in the lower component of the nasolabial angle over time between the SEG and CSG methods were not significant (P=0.815).

Conclusion: In this study, both columellar strut grafts and septal extension grafts methods showed similar changes in the position of the nasal tip over time. However, in the long term, changes in nasal tip elevation were greater in the SEG method compared to the columellar strut graft. It seems that changes in the position of the nasal tip decrease from the time of surgery to 6 months later.
