This review aims to synthesize current evidence on recurrence patterns, predictive models, and treatment strategies, with a focus on comparing Asian and Western populations. Materials and Methods: A structured narrative review was conducted by searching PubMed, Embase, and Cochrane Library from January 2010 to June 2025. A total of 116 studies were included based on predefined criteria regarding recurrence definitions, risk factors, prediction models, and postoperative management. Results: Recurrence rates ranged from 12% to 76.6%, with wide variability attributed to differences in follow-up duration and recurrence definitions. Key risk factors included tissue eosinophilia, comorbid asthma, and type 2 inflammation. Asian predictive models emphasized inflammatory biomarkers such as tissue and blood eosinophils, whereas Western models incorporated imaging, prior surgical history, and symptom burden. While biologics are widely used in the West, their adoption remains limited in Asia, where endotype-driven corticosteroid strategies are predominant. Conclusions: CRS recurrence after ESS is influenced by inflammatory endotypes, comorbidities, and regional treatment paradigms. Cross-regional differences in immune profiles and healthcare access necessitate the development of standardized definitions and validated, endotype-driven prediction tools. Tailored treatment strategies, especially for non-type 2 CRS, are essential to achieving equitable and effective care globally.<\/jats:p>","DOI":"10.3390\/medicina61091620","type":"journal-article","created":{"date-parts":[[2025,9,8]],"date-time":"2025-09-08T10:29:07Z","timestamp":1757327347000},"page":"1620","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Recurrence of Chronic Rhinosinusitis with Nasal Polyps After Surgery: Risk Factors, Predictive Models, and Treatment Approaches with a Focus on Western and Asian Differences"],"prefix":"10.3390","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4721-5590","authenticated-orcid":false,"given":"Yi-Shyue","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Otolaryngology, Head and Neck Surgery, National Taiwan University Hospital, Taipei 100225, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chi-Yu","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Medical Education, National Taiwan University Hospital, Taipei 100225, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-9280-2439","authenticated-orcid":false,"given":"Shih-Hao","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Medical Education, National Taiwan University Hospital, Taipei 100225, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Han","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Medical Education, National Taiwan University Hospital, Taipei 100225, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting-Hua","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Head and Neck Surgery, National Taiwan University Hospital, Taipei 100225, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4409-9474","authenticated-orcid":false,"given":"Chih-Feng","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Head and Neck Surgery, National Taiwan University Hospital, Taipei 100225, Taiwan"},{"name":"Institute of Medical Device and Imaging, National Taiwan University, Taipei 100225, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,8]]},"reference":[{"key":"ref_1","first-page":"e67910","article-title":"Factors Contributing to the Recurrence of Chronic Rhinosinusitis With Nasal Polyps After Endoscopic Sinus Surgery: A Systematic Review","volume":"16","author":"Abuduruk","year":"2024","journal-title":"Cureus"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"127","DOI":"10.2147\/JAA.S290424","article-title":"Burden of Disease in Chronic Rhinosinusitis with Nasal Polyps","volume":"14","author":"Bachert","year":"2021","journal-title":"J.
