METHODS: In a cadaver study with clinical correlation, we performed endoscopic endonasal harvest of the nasal floor free mucosal graft on two sides of a cadaveric nasal cavity. We also describe the cases of two patients in whom a nasal floor free mucosal graft was used to repair a skull base defect.
RESULTS: The harvest of a nasal floor free mucosal graft is a quick, potentially less morbid method of obtaining free mucosal grafts. In the cases examined, use of this graft carried minimal morbidity and allowed for successful reconstruction of a skull base defect.
CONCLUSIONS: Harvest of nasal floor mucosa is a technically simple method of obtaining free mucoperiosteum for reconstruction of the skull base.
