Biosynthetic porcine collagen dressings as an adjunct or definitive tool for the closure of scalp defects without periosteum.
Actas Dermo-sifiliográficas 2012 December
BACKGROUND: Aggressive carcinomas of the scalp usually occur in elderly patients with multiple comorbidities. Complete excision of this type of tumor often involves the removal of periosteum, and the resulting defects can be difficult to reconstruct.
OBJECTIVE: To evaluate the usefulness of porcine type I collagen dressings as adjunct or definitive treatment in the surgical closure of scalp defects without periosteum.
MATERIALS AND METHODS: We performed a prospective study between January 2009 and November 2011 of patients with scalp defects larger than 5cm resulting from surgery that required the removal of periosteum to obtain tumor-free margins.
RESULTS: The most prevalent type of tumor was recurrent cutaneous squamous cell carcinoma. The surgical defects ranged in diameter from 5 to 7cm. In 100% of the patients who received a graft after dressing removal (n=4), the graft took well. In the patients in whom the biosynthetic dressing was definitive (n=6), granulation tissue filled the defect and complete closure was achieved in approximately 3.5 months.
CONCLUSIONS: The use of porcine type I collagen dressings as an adjunct or definitive tool for the closure of surgical defects on the scalp measuring more than 5cm in which periosteum has been removed proved to be simple, inexpensive, and effective.
