Objective:
Several techniques are described in the literature for nasal septal perforation repair. Most of these involve interposition grafts in conjunction with local pedicled mucosal flaps. The following article describes our experience using acellular dermis as a bioscaffold to support the regrowth of nasal septal mucosa by secondary intention.
Methods:
Retrospective chart review of all patients who underwent repair of nasal septal perforations by the senior author using acellular dermis placed between the 2 sides of the perforation and covered with silastic splints to allow for mucosalization.
Results:
Thirteen patients underwent nasal septal perforation repair using this technique. All perforations repaired were under 2 cm in greatest dimension. Two-thirds of patients had complete closure of the perforation upon initial use of bioscaffolding technique. The remaining third achieved near-total closure with bioscaffolding technique and were able to be completely closed with a single additional procedure.
Conclusions:
Acellular dermis offers an alternative to most currently described complex flaps. The method can be used in patients with defects less than 2 cm, but initial data suggest caution when using in those with wound healing impediments. This technique is also an excellent choice for patients with multiple small septal perforations.
