Using the Helical Free Flap Based on the Retrograde Flow From Frontal Branch of Superficial Temporal Vessels in Lower...

Although the helical free flap is 1 of the most effective option for the lower third nasal reconstruction, the main limitation is still related to having a short pedicle length. In this report, the authors presented our experience in using the long pedicle helical free flap based on the frontal branch of the superficial temporal vessels in nasal reconstruction. Five patients, 3 alar full-thickness defects, 1 columellar defect, and 1 multiple subunit defect, underwent reconstruction using this technique. The pedicle length ranged from 4 to 6 cm. All the flaps were survived completely. However, vein congestion was seen post-operation in 1 case. This flap was saved by using medical leech. No vascular graft was needed. The helical free flap based on the retrograde flow of the frontal branch of the superficial temporal artery offers an option to overcome the limitation of short pedicle length. This composite flap is valuable for nasal alar and columellar reconstruction or even the larger defects, which involve multiple subunits.
