It is considered a relatively safe and effective procedure in all age groups, with overall success rates ranging from 76% to 97.5%. However, failure of primary endoscopic sinus surgery (PESS) occurs at a rate ranging from 2% to 24%. Patients who are still symptomatic after PESS and optimal medical therapy are candidates for revision endoscopic sinus surgery (RESS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>to study the outcomes of ESS and assess the risk factors of recurrence of nasal polyps, as well as to compare the outcomes of PESS and RESS at a tertiary care teaching hospital.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design<\/jats:title>\n                    <jats:p>A retrospective cross-sectional study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study is conducted on patients with CRS with nasal polyps (CRSwNP) who underwent ESS at King Saud University Medical City (KSUMC) between May 2015 and December 2021. During this period, ESS was performed 470 times for CRSwNP. The Sinonasal Outcome Test 22 (SNOT-22) questionnaire, the Lund\u2013Kennedy (LK) score, the Lund\u2013MacKay (LM) score, and the polyp grading system were used to evaluate subjective and objective outcomes. They were scored preoperatively and from 6 to 12 months postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Out of the 470 endoscopic sinus surgeries, 321 (68.3%) were PESS and 149 (31.7%) were RESS. Asthma, aspirin sensitivity, and Samter's triad were observed more in the RESS group. The LK and LM scores were significantly different between primary and revision sinus surgeries, revealing that PESS patients had better postoperative LK and LM scores. The RESS patients had significantly worse postoperative SNOT-22 scores compared to PESS patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Lund\u2013MacKay, Lund\u2013Kennedy, and SNOT-22 scores improved after ESS for both primary and revision ESS patients, with better outcomes observed after PESS compared to RESS. The presence of asthma, aspirin sensitivity, Samter's Triad, high-grade nasal polyps, and older age were identified as risk factors for CRSwNP recurrence, which may require RESS.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/27534030241274764","type":"journal-article","created":{"date-parts":[[2024,9,4]],"date-time":"2024-09-04T11:13:30Z","timestamp":1725448410000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Outcomes of Endoscopic Sinus Surgery for Chronic Rhinosinusitis With Nasal Polyposis and Risk Factors of Recurrence in a Tertiary Care Teaching Hospital"],"prefix":"10.1177","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8043-9096","authenticated-orcid":false,"given":"Ahmad","family":"Aldajani","sequence":"first","affiliation":[{"name":"College of Medicine, University of Jeddah"},{"name":"College of Medicine, King Saud University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5275-0255","authenticated-orcid":false,"given":"Ahmad","family":"Alroqi","sequence":"additional","affiliation":[{"name":"College of Medicine, King Saud University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Alrashidi","sequence":"additional","affiliation":[{"name":"College of Medicine, King Saud University"},{"name":"King Salman Specialist Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anas","family":"Alsaif","sequence":"additional","affiliation":[{"name":"King Saud University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saif","family":"Almeshari","sequence":"additional","affiliation":[{"name":"King Saud University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Aldwaighri","sequence":"additional","affiliation":[{"name":"King Saud University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saud","family":"Alromaih","sequence":"additional","affiliation":[{"name":"College of Medicine, King Saud University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad O.","family":"Aloulah","sequence":"additional","affiliation":[{"name":"College of Medicine, King Saud University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulaziz S.","family":"Alrasheed","sequence":"additional","affiliation":[{"name":"College of Medicine, King Saud University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Surayie","family":"Aldousary","sequence":"additional","affiliation":[{"name":"College of Medicine, King Saud University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1236-2098","authenticated-orcid":false,"given":"Saad","family":"Alsaleh","sequence":"additional","affiliation":[{"name":"College of Medicine, King Saud University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,9,3]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.4193\/Rhin20.401"},{"issue":"4","key":"e_1_3_4_3_2","first-page":"199","article-title":"Chronic rhinosinusitis","volume":"13","author":"Dickson E","year":"2020","unstructured":"Dickson E, Hopkins C.
