Lateral crural transposition flap in tip correction: Tehran retrospective rhinoplasty experience.

Purpose: 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.

Materials And Methods: 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.

Results: 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.

Conclusions: 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.
