Abstract
This study aims to review the authors' experience with the lower lateral crura (LLC) transposition flap in an attempt to highlight its advantages, indications, and limitations. A retrospective study of 37 rhinoplasties (29 primary cases, 7 secondary cases, and 1 tertiary case) was performed. In all of these, an LLC transposition flap was used by inserting the cephalic portion of the LLCs into a subperichondrial pocket between the medial aspect of the remaining rim strip and the vestibular skin, based on the posterior pedicle. The most prevalent symptom among our patients was nasal external valve dysfunction. Concavity of the LLCs was very common. The LLC transposition flap can correct the LLC deformities with a high rate of patient satisfaction and no need for revision operations. The LLC transposition flap can overcome the common irregularities of the LLCs and could be applied to primary and secondary rhinoplasties, as well as ethnic noses.
