Herein, we introduce an innovative stent in rhinoplasty for Asians, which is an application of this concept.

External Z-plasty Technique for Correction of Alar Retraction in Asian Patients.

Background: Current strategies for correcting alar retraction mainly include cartilage grafting and composite grafting, which are relatively complicated and may produce injury to the donor site. Herein, we introduce a simple and effective external Z-plasty technique for correcting alar retraction in Asian patients with poor skin malleability.

Methods: Twenty-three patients were presented with alar retraction and poor skin malleability, and they were very concerned about the shape of the nose.

Designing a Trifoliate Flap for Isolated Congenital Alar Rim Defect in Pediatric Patients.

Isolated congenital alar rim defects are extremely rare, and there has been no standard technique for the reconstruction of remarkable aesthetic deformity. Herein, we introduce a trifoliate flap for the correction of isolated congenital alar rim defects in pediatric patients. Fifteen cases undergoing nasal alar sulcus rotation flap surgery were analyzed retrospectively.
