Advances in Absorbable Biomaterials and Nasal Packing.

: Nasal biomaterials have been developed to improve postoperative outcomes after functional endoscopic sinus surgery (FESS). These products have been designed to overcome certain common complications in FESS, and to maximize patient comfort. This article evaluates the performance of nonabsorbable and absorbable packing with respect to these outcomes. The collected trials suggest superior performance of bioabsorbable packs compared with absorbable packs with respect to patient comfort. For hemostasis and wound healing, variation in performance metrics makes interstudy comparison difficult. Before further trials are conducted, consensus must be reached among rhinologists as to the proper method of evaluating these products.
