A novel surgical technique to correct caudal and high dorsal septal deviations: L-shape cutting and suturing on the septal L-strut (L-septoplasty)

[摘要] Objectives In general, deviation of the L-strut of the nasal septum is more challenging to correct than the middle and has less favorable results. This study aimed to develop a technique to correct the L-strut while preserving nasal support effectively and introduce the L-septoplasty technique and its effects. Methods Patients with caudal and high dorsal septal deviations who underwent the L-septoplasty technique were retrospectively analyzed. Preoperative and three-month postoperative comparative assessments included the Nasal Obstruction Symptom Evaluation (NOSE) scale and minimal cross-sectional area (MCA). Results Thirty patients seen at a tertiary care center were included. NOSE scale scores improved from 47.2 to 13.6, which was statistically significant ( P  < .001). MCA increased from 0.43 cm 2 to 0.74 cm 2 ( P  < .001). During the 3-month follow-up period, deviation correction was well maintained in all patients, and no surgical complications, such as saddle nose deformity, occurred. Conclusion The L-septoplasty technique is effective in simultaneously correcting caudal and high dorsal septal deviations without any complications. Level of evidence 4.
