Purpose: Reconstruction of a full thickness defect of the nose is a difficult task for plastic surgeons because the anatomical characteristic, shape, and function of the nose all need to be taken into consideration. Most often, a local flap or a composite graft is used, but for a large defect, reconstruction using free flaps is the most ideal method. In free flap reconstruction, the chondrocutaneous preauricular area can be a suitable donor site. We performed a chondrocutaneous preauricular free flap with an interpositional vascular graft for reconstruction of a nasal ala.
Methods: A 46 year-old male presented to the hospital with a right alar deformity induced by a dog bite. During the surgery, the existing scar tissue was removed and thereby a newly formed full thickness defect was reconstructed using the chondrocutaneous preauricular free flap with an interpositional vascular graft harvested from the descending branch of the lateral femoral circumflex vessel between the facial and superficial temporal vessels of the free flap.
Results: The flap survived without flap loss and showed symmetry in its overall shape, contour, texture, and color. The patient was satisfied with the results and the surgery yielded no additional scars at the nasolabial fold area.
Conclusion: The chondrocutaneous preauricular free flap is a valuable method in reconstruction of full thickness defects of the nose, and using the descending branch of the lateral femoral circumflex vessel as the interpositional vascular graft at the anastomotic site produces reliable results.
