Secondary reconstruction of burned nasal alae using rolled dermal flap with overlying full-thickness skin graft.

INTRODUCTION

Surgical reconstruction of the nasal tip is a very delicate procedure, as it must rebuild three different anatomical planes: mucosa, cartilage and skin with functional and aesthetic requirements. This procedure is even more difficult in burns patients, due to more limited donor sites and poor skin quality. Numerous flap options are available to reconstruct defects of the tip of the nose. The authors report their experience of nasal alar reconstruction by a scar tissue remodelling technique using a rolled dermal flap with overlying full-thickness skin graft.

PATIENTS AND METHODS

The medical charts of seven patients (five women and two men with a mean age of 30) treated between 1991 and 2006 were retrospectively reviewed. Six patients presented sequelae of a facial burn and one patient had congenital facial hemiagenesis.

RESULTS

Reconstruction was bilateral for all burns patients and unilateral for the patient with facial hemiagenesis. The skin graft was raised from the medial aspect of the forearm in four cases, the retroauricular region in two cases and the groin in one case. One patient required a second surgical procedure for necrosis of the nasal tip. No nasal obstruction was reported with a mean follow-up of five years (range: six months to 15 years).

CONCLUSION

The rolled dermal flap with overlying full-thickness skin graft is a simple and reliable procedure for reconstruction of the nasal alae. Filling of the nasal alae defect and reconstruction of all anatomical planes are achieved in a single surgical procedure. The aesthetic and functional results were satisfactory, with minimal scarring of the donor site. This technique is very suitable for the treatment of burn sequelae and can also be used to treat nasal hemiagenesis and nasal mutilation by biting or facial trauma.
