Mobile Bony Cap (Meysem Yorgun Technique): An Innovative Technique in Preservation Rhinoplasty for Crooked Nose Deformity.

Abstract

This study included 25 patients with I- or C-shaped crooked nose deformities who underwent correction with a closed-approach let-down procedure. In this technique, the middle vault is preserved, the bony cap is mobilized and preserved, and the lateral nasal bones are equalized by a piezo device or classical osteotomes. By the mobilization of the bony cap, tension on the dorsal septum is released, and slight asymmetries are hidden behind this mobile bony cap. The postoperative angles for both type I and C deformities were closer to the ideal angle, and the difference was statistically significant. All patients were satisfied with their aesthetic and functional results. In this procedure, we correct asymmetries at the lower maxillary nasal junction, such as in the let-down approach, as well as asymmetries at the K-point, such as in the structural approach. Thus, we combine the advantages of both techniques. Additionally, the mobile-bony cap left on the patient is very useful for releasing the tension of the septal dorsum and hiding slight asymmetries that remain below in the patients.
