Correction of an alar web with a feather-edge rolled-in flap.

The aim of this study was to see the histological nature of the alar web and to introduce a featheredged rolled-in flap to reduce the alar web.On a cadaver, the perpendicular section of the alar web revealed a thickened dermis portion on both the skin side and the nasal side distal to the alar cartilage. According to histological results, we thought the thinning and rolling in of the distal margin of the end of the open rhinoplasty incision could reduce the alar web. An open rhinoplasty incision was made just distal to the hair-bearing vestibular skin and a V-Y shape incision created at the alar base. After the cartilage work, the skin of the distal end of the flap was featheredged to a 0.5-mm thickness. The distal margin was rolled in and sutured to the nasal lining. A bolster dressing was applied using a 4-0 nylon suture.Thirteen patients (8 males, 5 females) were operated on, and 8 patients were followed up for more than 12 months. Their preoperative and postoperative worm's eye views were compared. Four anthropometric distances were measured preoperatively and postoperatively. The columellar length increased significantly after the operation (P = 0.001 [independent 2-sample t test]) on the cleft side. Preoperatively, the alar width was significantly greater (P = 0.02 [paired-samples t test]) on the cleft side (0.17 ± 0.03 of an intercanthal distance) than the noncleft side (0.14 ± 0.03). After the operations, they became similar (0.16 ± 0.03 on cleft side, 0.16 ± 0.04 on the noncleft side; P = 1.00 [paired-samples t test]).We think this featheredged rolling-in flap might be a good method for the correction of an alar web since this technique increased the columellar length and decreased the alar width on the cleft side.
