Comparison of the Novel “Boomerang Suture” Technique Used in Fixing the Nasal Septum to the Anterior Nasal Spine of the Maxilla with Figure-of-8 Suture

Objective: In this study, we described the boomerang suture technique to attach the nasal septum to the anterior nasal spine. We evaluated its outcomes and compared it with the traditional figure-of-8 suture technique. Methods: This study was carried out on BO patients who underwent nasal surgery (boomerang suture in 40 patients and figure-of-8 suture in 40 patients) between September 2016 and January 2019. The decision to use the boomerang suture or figure-of-8 suture technique was randomized in a sequential fashion. The detected deviations and applied septoplasty methods were given. The surgical results were determined by the independent observers' scorings. The Nasal Obstructive Symptom Evaluation scale was applied before and 1 year after surgery. A computer simulation was utilized to analyze the features of the techniques. Results: The most commonly used technique was the swinging door in 39 cases. Postoperative Nasal Obstructive Symptom Evaluation scale values were statistically lower than preoperative in both groups (P <.001). Surgical success rates for boomerang suture and figure-of-8 suture techniques were 97.5% and 87.5%, respectively, which were not statistically significant (P=.201). Boomerang suture can produce 4.3 times more vertical vectors than figure-of-8 suture, and figure-of-8 suture causes 3.7 times more torque in the same amount of misalignment in the biomechanical analysis. Conclusion: The boomerang suture and figure-of-8 suture are very successful techniques to fix the nasal septum. The boomerang suture technique, which creates a much larger vertical vector and less rotational force than the figure-of-8 suture, was also more successful, although it was not statistically significant.
