Evaluation of the Effectiveness of Lateral Intercrural Suture to Reduce Interdomal Distance in Order to Improve Nasal Tip Definition on Primary Rhinoplasty
Introduction: Several surgical techniques emphasizing sutures on the lower lateral cartilage have been studied by surgeons as instruments to improve nasal tip remodeling. It is already known that the domal divergence angle and its definition angle can be modified by lateral intercrural suture (LIS). Techniques for measuring these structures are not yet standardized. Objectives: Assess the efficacy of LIS using polydioxanone 4.0 absorbable thread by interdomal distance measure on primary rhinoplasty and systematize lateral intercrural suture technique to improve nasal tip definition. Material and methods: Measurement and analyses of interdomal distance measures collected in the pre-operative and trans-operative in comparison with the third and sixth month of post-operative. Prospectivestudy. Results: Lateral intercrural suture (LIS) has proved to be efficient on reducing interdomal distances. Conclusion: LIS is statistically safe, efficient and of low morbidity when utilized in patients with mild to moderate deformities, because it reduces the domal divergence angle, offering effective sustentation to the nasal tip.
