In ENT surgery, Arista is applied in which procedure?

• A. Tonsillectomy
• B. Cochlear Implant
• C. FESS
• D. Septoplasty

Answer: (C)

Arista is a cellulose-based hemostatic sponge designed to produce rapid local hemostasis on mucosal surfaces. In functional endoscopic sinus surgery, the nasal passages and sinus mucosa can bleed easily and unpredictably, and maintaining a clear field is crucial for safe, precise work. When applied to the bleeding surface, Arista absorbs blood, swells into a porous matrix, and acts as a scaffold that concentrates clotting factors and platelets. This mechanical tamponade plus the clotting environment helps stop the bleeding quickly and conforms to the irregular sinus anatomy, improving visualization and allowing the surgeon to continue the procedure. It’s designed to be well tolerated and is eventually absorbed, making it especially suitable for the confined nasal/sinus space. This is why Arista is typically associated with functional endoscopic sinus surgery rather than other ENT procedures like tonsillectomy, cochlear implantation, or septoplasty.
