Guitar-String Suture to Facilitate Closure of a Finger-like Flap for Reconstruction of the Nose. Scientific Publication

Introduction: The basic principle of a lobed or finger-like transposition flap is that, after covering the defect with the transposed tissue, the donor site is closed primarily. With large defects, a second lobe may be added to the flap if primary closure of the area left by the first lobe is not possible. The flap can often be made to adapt to the defect, but this maneuver, in combination with primary closure of the adjacent tissue, can sometimes produce excessive tension and compromise the blood supply.

Material and methods: We present a series of 4 patients with epithelial tumors of the lateral wall of the nose. The defects left by surgical excision were covered by finger-like transposition flaps. Subcutaneous sutures called guitar-string sutures were used to reduce the size of the defect and facilitate tension-free closure.

Conclusions: We propose use of the guitar-string subcutaneous suture in those cases in which the defect is larger than the area that can be covered by the flap. This will make it easier to adapt the flap to the defect and will reduce the risk of excessive tension causing necrosis of the transposed tissue.
