Two Cases of Unilateral Nasoseptal Pedicled Rotational Mucosal Flap and Interpositional Dermal Allograft for Septal Perforations / 대한이비인후과학회지

ABSTRACT

A nasoseptal perforation is a defect of cartilage, bone, and mucosa of nasal septum, caused by nasal surgery, malignancy, inflammation, or drugs. Although various surgical treatments and procedures are well known, there is no consensus on the procedures due to low success rate (25-90%) and high recurrence rate (12-48%). One of the major factors that affect surgical results is the size of perforation. For large perforations, the surgical success rate is reported to range from 23% to 70%. The authors report two successful cases of repair surgery of nasoseptal perforation, using unilateral pedicled nasoseptal rotational mucosal flap with releasing incision and interpositional dermal allograft. Although larger study populations and long-term follow-up periods are needed, the authors believe that our method is an effective way to minimalize possible inconveniences observed in the cases of comparatively large perforations, or where there is a lack of autografts or donor site defects.
