A spectrum of absorbable biomaterials is available for revision endoscopic sinus surgery. • Each of these agents has unique properties that impact on both the mode of application and mucosal healing. • The anatomy of revision sinonasal cavities exhibits significant variability depending upon the extent of previous surgery and the healing process. • The mucosa of patients with recalcitrant disease undergoing revision sinus surgery may exhibit significant qualitative differences compared to that of primary cases. • Roles of absorbable biomaterials include potential impact on hemostasis as well as mucosal healing. • Properties differ between the available products. • A complete understanding of the unique features of available bioabsorbable agents and their tissue effects is crucial, so that the appropriate material may be selected for a particular revision surgery.
