A combined flap reconstruction for full-thickness defects of the medial canthal region.

摘要

The medial canthus is an aesthetically and functionally important area. Adequate consideration of the local anatomy is essential when reconstructing this area. We developed a combined flap technique with a simple combination of standard flaps for the treatment of extensive defects of the nose and upper and lower eyelids, including full-thickness medial canthus defect. In our technique, a median forehead island flap is used for the nasal region, the anterior surface of the eyelid is reconstructed along aesthetic unit, and the posterior surface is reconstructed with a palatal mucoperiosteal graft. A cheek flap is then used for the reconstruction of the lower eyelid. When reconstructing a small defect of the upper eyelid, the upper eyelid is advanced, while a V-Y advancement flap within the upper eyelid is used for a large defect. To reconstruct the acute angle of the medial canthus, a 0.3 mm titanium wire was passed through the tip of the tarsal plate of the upper and lower eyelids to be reconstructed and was fixed in the perforated nasal bone on the affected side. Using this technique, the acute angle of the medial canthus is well preserved after surgery, and is located symmetrically with its counterpart on the intact side. Our technique provides good reconstructive results and should serve as a valid alternative for the reconstruction of this area.
