[Revision of surgical treatment of rhinosinusitis]

The aim of this revision paper is to provide an update of available resources to achieve the best endoscopic sinus surgery outcomes of adult rhinosinusitis. The cause and mechanisms of rhinosinusitis remain unknown, and curative treatment does not exist. Recent new insights into paranasal sinus pathophysiology, along with technical advances in imaging and endoscopy, have revolutionised surgical treatment of rhinosinusitis. Since an increasing number of patients undergo functional endoscopic sinus surgery as a therapeutic regimen for their disease, appropriate use of computed tomography is critical in providing a "roadmap" for the surgeon to delimit the surgical procedure, as well as to ensure safety and accuracy. With proper training and technique, endoscopic surgery is quite safe, but prevention and management of complications must be known.
