The use of a failed flap as a biological dressing.

A patient with a narrowly excised squamous cell carcinoma on the scalp underwent a wider excision that involved burring of the underlying calvarium. The defect was reconstructed with a superficial temporal artery pedicled flap, which unfortunately failed. The patient had multiple co-morbidities, limiting reconstructive options. The failed flap was therefore maintained as a 'biological dressing' for several weeks. During this time, the patient was reviewed regularly in the dressing clinic and did not develop a wound infection. Six weeks later, he was taken back to theatre and the flap was debrided under local anaesthesia. Beneath the flap, there was sufficient healthy granulation tissue over the site of previous bony debridement to permit split skin grafting. We advocate this technique as a useful method for managing difficult wounds in complex patients with multiple co-morbidities where other reconstructive techniques are limited.
