“…11 Mucosal grafting must be oriented carefully to ensure placement of the mucosal surface toward the nasal cavity or sinus to prevent mucocele formation or other intracranial complications. Nonmucosal soft graft materials consist of fascial grafts, fat, skin grafts, bone pate, 12 Duragen, and Alloderm, and firm grafts include cartilage, bone, Medpor (Stryker, Newnan, GA), and hydroxyapatite cement grafts. Once the primary graft monolayer or multiple layers are positioned, a variety of sealants and packing can be utilized to stabilize the graft during its initial healing and adherence to the defect site, including DuraSeal, GelFilm (Pfizer, New York, NY), Tisseel, Gelfoam, and Surgicel (Ethicon, Cornelia, GA).…”
