Packing in endonasal surgery.

Nasal packing is used to control bleeding in epistaxis and after endonasal surgery, for internal stabilization, and to prevent synechiae or restenosis, particularly after surgery. Generally accepted standards regarding the materials that should be used for packing, how long the packing should be left in place, or the indications for nasal packing are lacking. In view of the present lack of standardization and the many different packing materials used, we review the currently available materials and outline their respective properties, indications, and risks.
