Abstract

Background
Rhinosinusitis, one of the most common conditions encountered by clinicians, affects quality of life and reduces work productivity. Despite its high prevalence and economic burden, there are considerable differences in practice regarding the management of rhinosinusitis. Based on many studies, including the updated guidelines, classifications have been subdivided, and new treatments have been added.
Current Concepts
Rhinosinusitis can be classified as acute rhinosinusitis (ARS) or chronic rhinosinusitis (CRS) with a cut-off duration of 12 weeks. It is diagnosed based on subjective symptoms and objective findings on computed tomography or endoscopy. Viral infections account for the majority of the causes of ARS, with watchful waiting without antibiotics as its important initial management. Meanwhile, CRS is divided into primary and secondary CRS, which is further subdivided by anatomic distribution and endotype. Particularly, the Type 2 endotype is characterized by a high recurrence rate and high resistance to current therapies. Biologics using monoclonal antibodies could therefore be used as new therapeutic options for the treatment of primary type 2 CRS. Furthermore, given the chronicity of CRS, it is important to recognize that endoscopic sinus surgery and continuous postoperative medical treatment are important for its management.
Discussion and Conclusion
Accurate diagnoses based on diagnostic criteria and subdivided classifications are necessary to determine the treatment plan and prognosis. In particular, it is important to differentiate the endotype of CRS and provide appropriate treatments to improve the patient’s symptoms and quality of life.
