Application of the Multi-line Tension-Reduction Technique in the Surgical Correction of C-shaped Deviations of the Nasal Septum

Objective This study aims to evaluate the efficacy of the multi-line tension-reduction technique in the surgical correction of a C-shaped nasal septum deviation. Methods This study included patients diagnosed with a C-shaped nasal septum deviation who underwent nasal septum correction surgery. Participants were divided into two groups: an observation group, in which the multi-line tension-reduction technique was applied, and a control group, in which traditional surgical methods were used. The following parameters were compared between the two groups: operation time, intraoperative blood loss, postoperative pain intensity (assessed using the visual analog scale (VAS)), improvement in nasal ventilation (measured using a nasal resistance meter), and complication rate. Results In the observation group, the mean operation time was 35.22 ± 5.48 minutes and the mean intraoperative blood loss was 10.53 ± 4.07 mL, both of which were significantly lower than those in the control group (t = 7.84, 16.215; P < 0.05). The postoperative pain intensity, as assessed by VAS scores at 24, 48, and 72 hours, was 5.23 ± 1.23, 2.48 ± 1.09, and 0.68 ± 0.76 points, respectively, all of which were significantly lower than those in the control group (t = 8.11, 11.80, 8.383; P < 0.05). The complication rate in the observation group was 2.5%, which was significantly lower than that in the control group (χ² = 3.97; P < 0.05). Nasal ventilation resistance values at 1, 3, 6, and 12 months post-operation were 0.87 ± 0.12, 0.66 ± 0.16, 0.64 ± 0.13, and 0.61 ± 0.14, respectively, all of which were significantly lower than those in the control group (t = 9.221, 9.477, 8.923, 7.212; P < 0.05). These findings indicate that the multi-line tension-reduction technique significantly outperformed traditional surgical methods in terms of operation time, intraoperative blood loss, postoperative pain intensity, nasal ventilation improvement, and complication rate. Conclusion The application of the multi-line tension-reduction technique in the surgical correction of a C-shaped nasal septum deviation exhibits substantial advantages such as reduced operation time, minimized intraoperative blood loss, attenuated postoperative pain, improved recovery of nasal ventilation function, and a significantly lower complication rate.
