Nasal reconstruction after severe facial burns using a local turndown flap.

Abstract：

:Reconstruction of the nose after severe burn injury is a challenging problem. There are usually associated facial burns, which limits the availability of local flaps. Reconstruction with unburned distant tissue is often not appropriate because of the resulting mismatch in color and texture. Successful nasal reconstruction can be accomplished in this group of challenging patients using a simple, inferiorly based flap from the nasal dorsum with subsequent skin grafting to the resulting defect. We have used an inferiorly based nasal turndown flap to reconstruct severe nasal deformities after burn injury in 28 patients. The flap tissue consists of the dorsal surface of the nose, which is usually made up of skin graft and scar. The flap base is the scar transition zone between the dorsum of the nose and the lining mucosa. This is turned over to provide nasal length, projection, and to stimulate alar lobules. The resulting defect on the dorsum of the nose is then skin grafted. If further length or refinement is required, the procedure may be repeated. The records of all patients who underwent this procedure were reviewed for demographics, age at burn, percentage of total body surface area burned (%TBSA), availability of the forehead, number of procedures, and complications. Twenty-eight patients underwent nasal reconstruction in our series using this local turndown flap. Most of these patients had severe burns, with an average %TBSA of 46%. The procedure was initially applied to patients with devastating injuries and %TBSA of 80%-95%, with extremely limited donor sites. As the success of the procedure was established, less severely burned patients were included in the series, thereby lowering the mean %TBSA. All patients had partial or complete destruction of their forehead donor site. All patients presented for multiple hospitalizations, with an average of 17 hospital admissions. Using this local turndown flap, adequate nasal length and projection could be achieved. There were few complications. All of the flaps survived, although there were 2 cases of necrosis of the distal edge of the flaps (0.7%). This resulted in decreased length and projection but this problem was successfully addressed with additional staged procedures. Contraction of local scar tissue created bulk and support, eliminating the need for distant tissue transfer or cartilage grafting. Twelve of the 28 patients required repeat turndown flaps to achieve sufficient nasal length and projection. These results were durable over a follow-up period of up to several decades. A simple, multistaged dorsal nasal flap can be used to reconstruct severe nasal deformities after facial burn injury. This can obviate the need for distant tissue transfer. Even in patients with subtotal nasal amputation and complete absence of cartilaginous support, the opportunistic use of scar tissue can restore nasal tip projection and alar lobule architecture without cartilage grafting. The resulting nasal reconstruction blends well into the surrounding facial appearance. This simple technique has been remarkably successful in this selected group of patients with challenging nasal deformities.
