Surgical correction of the lower lateral cartilage protrusion and external nasal valve pinching with lateral crural resection technique.

[OBJECTIVE] The aim of this study is to demonstrate a novel surgical technique in the treatment of lower lateral crural protrusion and external nasal valve pinching.

[METHOD] The lower lateral crural resection technique was used in 24 patients who underwent open technique septorhinoplasty between 2019 and 2022. Fourteen of the patients were female and 10 were male. In this technique, excess part of crura's tail was excised from the lower lateral crura and placed in the same pocket. This area was supported with a diced cartilage and a postoperative nasal retainer was applied. We have corrected the aesthetic problem that occurs when the lower lateral cartilage is convex, and external nasal valve pinching that occurs when the lower lateral crural protrusion is concave.

[RESULT] The mean age of the patients was 23. The mean follow-up time of the patients was between 6 and 18 months. No complications were observed due to this technique. Satisfactory results were obtained in the postoperative period after surgery.

[CONCLUSION] A new surgical approach has been proposed for patients with lower lateral crural protrusion and external nasal valve pinching using the lateral crural resection technique.
