OBJECTIVE In our study, we showed that the septal extension graft (SEG) technique, which we applied for nasal projection in rhinoplasty surgery, increases the tension of the lateral cartilage (LC) and alar structures. We also demonstrated that nasal congestion could be treated by applying this technique in patients with nasal obstruction due to bilateral dynamic alar collapse. PATIENTS AND METHODS This study was conducted retrospectively on 23 patients with nasal obstruction due to alar collapse. Bilateral dynamic nasal collapse and (+) Cottle test was present in all patients. Nasal lateral wall tissue was also found flaccid on nasal palpation and collapsed to the extent of obstruction on deep inspiration. Standard septal extension graft (SEG) and tongue-in-groove techniques were applied to all patients. RESULTS Septal cartilage was used for SEG in all patients. No complaints of nasal obstruction on deep inspiration were noted by the patients at six months postoperative follow-up, and Cottle tests were negative. The patients' mean respiratory score was 152 postoperatively, compared to 66.5 preoperatively. This difference was statistically significant using the Wilcoxon signed ranks test (p<0.001). In evaluating postoperative cosmetic appearance due to nasal tip projection (NTP) and cephalic rotation changes, 16 men and four women reported that it was better, while two men felt that there was no change. One woman reported that her cosmetic appearance was worse than before; a revision surgery was performed for her at seven months postoperatively. CONCLUSIONS This method is effective for patients with bilateral nasal collapse and thick-short columella. With the applied surgery, the caudal edge of the LC diverges from the septum, alar region tension and resistance increase, the columella increases in length, nasal projection increases, and the vestibule cross-sectional area is enlarged. In this way, a significant increase in nasal vestibular volume was obtained.
