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. These patients undergoing external Z-plasty surgery were analyzed retrospectively. In this surgery, no grafts were needed, and the location of the Z-plasty was according to the highest point of the retracted alar rim. We reviewed the clinical medical notes and photographs. During the postoperative follow-up period, patients' reported satisfaction with aesthetic outcome were also evaluated.

Results: The alar retraction of all the patients was successfully corrected. The postoperative mean follow-up period was 8 months (range: 5-28 mo). No incidents of flap loss, recurrence of alar retraction, or nasal obstruction were observed during postoperative follow-up. Within postoperative 3-8 weeks, minor red scarring was visible at the operative incisions in most patients. However, these scars turned unobvious after postoperative 6 months. There were 15 cases (15/23) being very satisfied with the aesthetic outcome of this procedure. Seven patients (7/23) were satisfied with the effect and the invisible scar of this operation. Only one patient was dissatisfied with the scar, but she was satisfied with the correction effect of the retraction.

Conclusion: This external Z-plasty technique can be an alternative method for correction of alar retraction with no need of cartilage grafting, and the scar can be unobvious with fine surgical suture. However, the indications should be limited in patients with severe alar retraction and poor skin malleability, who should not particularly care about the scars.
