Intranasal Z-plasty for internal nasal valve collapse

To describe the technique of intranasal Z-plasty and early results for this minimally invasive method to repair internal nasal valve collapse. Intranasal Z-plasty has been well described for nasal valve stenosis and cleft nasal deformities but poorly described for idiopathic nasal valve collapse, the most common indication for nasal valve surgery.

A retrospective medical record review was performed for 12 patients undergoing intranasal Z-plasty for nasal valve collapse. Medical records were evaluated for age, sex, indication for surgery, prior surgical procedures, complications, results, and length of follow-up. A visual analog scale was used to rate nasal obstruction preoperatively and postoperatively.

A total of 8 men and 4 women underwent surgery, and the procedure was bilateral in 10 of the 12 patients, for a total of 22 nasal valves. Eleven patients noted subjective improvement in airflow on both sides, with the remaining patient noting improvement on one side and no change in the opposite side. Mean follow-up was 16.8 months (range, 5-32 months). The mean preoperative nasal obstruction score was 7.2, and the mean postoperative nasal obstruction score was 3.3 (on a scale of 0 to 10, with 10 being total obstruction). No complications were reported, and no patients complained about postoperative nasal appearance.

Intranasal Z-plasty appears to be a safe, effective, and relatively noninvasive technique to repair internal nasal valve collapse.
