Background: Knowing the long-term consequences or side effects induced by various types of strut and septal extension grafts following rhinoplasty are essential and aid in estimating and predicting difficulties later. The purpose of this study is to look at how the projection of the nose tip changes following rhinoplasty with the L-shape strut, a new type of septal extension. Aim: We aimed to determine the changes in nasal projection in patients who received an L-shaped strut at 6 and 12 months’ post-operation. Methods: Following inclusion and exclusion criteria, an L-shape strut was prepared from the patient's septal cartilage and used in the surgery. We objectively assess the results of the L-shape strut with standard images. These standard images were taken before surgery and on the day of the nasal splint off, six-and twelve-months after surgery. Then the nasal projection was calculated using Goode's ratio. Results: Thirty patients were included. The mean Goode's ratio was 0. 573 ± 0. 014 shortly after surgery, all participants had a ratio between 0. 55 and 0. 60. After 6 and 12 months of follow-up, the measured Goode ratio of the participants was 0. 556 ± 0. 024 and 0. 550± 0. 027, respectively. Thus, the observed ratio declined by 2% during the first six months, and 1 % during the second six months. This decreasing pattern was statistically significant. After twelve months of follow-ups, Goode's ratio of all included cases was in the optimal range of 0. 55 to 0. 6. Conclusion: The findings of this study demonstrate that the L-shape strut, a new type of septal extension, can help to keep the optimal Goode’s ratio after a year follow-up.
