There was a roughly even split between patients with chronic sinusitis with and without nasal polyps (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200910,\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20099). Under half (42.1%) of skull base injuries were identified intraoperatively, all injuries occurred to the ethmoid skull base, and there was a predisposition toward right-sided injury. All patients underwent endoscopic repair with a 100% success rate. Two patients (10.5%) were started on acetazolamide postoperatively, both with a body mass index greater than 40.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our findings underscore the importance of maintaining a high degree of suspicion for skull base injury as well as understanding endonasal anatomy and patient-to-patient variations. Our work adds to the literature suggesting a higher-than-suspected rate of missed skull base injury during sinus surgery. We anticipate an impending increase in iatrogenic injuries managed in the secondary setting, reflecting the trend toward sinus procedures being performed in the office setting. We recommend a thoughtful patient-specific approach toward secondary management, including evaluating for intracranial injury for suspected penetrating trauma and tailoring reconstruction to the particular defect.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/19458924251341765","type":"journal-article","created":{"date-parts":[[2025,5,14]],"date-time":"2025-05-14T19:29:07Z","timestamp":1747250947000},"page":"345-352","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Secondary Repair of Iatrogenic CSF Leak During Sinus Surgery in a Tertiary Care Center"],"prefix":"10.1177","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0431-2920","authenticated-orcid":false,"given":"David K.","family":"Lerner","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, University of Miami, Miami, FL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helene","family":"Chesnais","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9086-167X","authenticated-orcid":false,"given":"Louis-Xavier","family":"Barrette","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan D.","family":"Workman","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, Massachusetts Eye and Ear, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jillian W.","family":"Lazor","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3634-2067","authenticated-orcid":false,"given":"Jennifer E.","family":"Douglas","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8399-364X","authenticated-orcid":false,"given":"Michael A.","family":"Kohanski","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nithin D.","family":"Adappa","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James N.","family":"Palmer","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2014Head and Neck Surgery, University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,5,14]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200402000-00015"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.otc.2008.01.005"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2017.09.076"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.4193\/Rhin16.169"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/alr.21637"},{"issue":"8","key":"e_1_3_2_7_2","article-title":"Missed skull base injury during sinonasal surgery: a dangerous scenario still existing","volume":"94","author":"Hassab MH","year":"2015","unstructured":"Hassab MH, Eweiss AZ, Ibrahim AA.
