Comparison of Transalar Suture Technique and External Wedge Resection for Alar Base Narrowing

Alar narrowing is indicated in some rhinoplasty operations. This study compared transalar sutures and external wedge resection for alar narrowing in patients undergoing rhinoplasty.

This study was a single-blind randomized controlled trial with a parallel design. Participants were allocated randomly to the transalar suturing technique group or the external wedge resection group (one-to-one allocation ratio). Primary outcomes were scar formation and satisfaction score (Rhinoplasty Outcome Evaluation questionnaire and patient component of Patient Scar Assessment Questionnaire) after 12 months. Secondary outcomes were the duration of procedure, amount of bleeding, and need for bleeding control.

In total, 44 and 46 patients completed the study in the transalar suture and external wedge resection groups, respectively. The postoperative assessment showed a significantly lower scar formation rate in the transalar suture group (75.0% versus 37.0%; P < 0.001). The Rhinoplasty Outcome Evaluation questionnaire revealed no statistically significant difference in patient satisfaction between two groups. The Patient Scar Assessment Questionnaire results showed that patients who received transalar sutures had a lower overall score (1; interquartile range, 1 to 1) compared with the external wedge resection group (2; interquartile range, 1 to 4.50) ( P < 0.001). The duration of the procedure ( P < 0.001), amount of bleeding ( P < 0.001), and need for bleeding control ( P = 0.009) were significantly lower in the transalar suture group than in the external wedge resection group.

Transalar sutures result in high postoperative patient satisfaction. This approach has a decreased incidence of scarring, operation time, bleeding, and necessity for bleeding control.
