Assessment of effectiveness of cantilever versus spreader grafts in functional septorhinoplasty: an interventional cohort study

Objectives This study aims to compare the effectiveness of the spreader grafts and cantilever grafts in correcting the narrow internal nasal valve in patients undergoing functional septorhinoplasty. Methods This ambispective interventional cohort study, involving 50 patients who underwent septorhinoplasty between December 2020 and November 2023 at our tertiary-care referral hospital, with 25 receiving spreader grafts (control group) and 25 undergoing surgery with cantilever grafts. Results The results showed a significant improvement in nasal airflow in both groups post-operatively, with the cantilever graft group showing a slightly higher improvement than the spreader graft group, although not statistically significant ( p = 0.062). Conclusions Septorhinoplasty is a surgical procedure that aims to improve both the aesthetic appearance of the nose and nasal function. While spreader grafts are considered a standard technique for aesthetic improvement, the balanced cantilever graft offers a promising alternative for functional enhancement, particularly in patients with a narrow internal nasal valve.
