Thus, early diagnosis is crucial for optimal management. This study presents 2 cases of paranasal schwannomas, detailing their clinical presentation, diagnostic methods, and treatment approaches. Both patients underwent endoscopic sinus surgery with successful tumor excision and had no significant complications or recurrences during follow-up. Diagnosis was based on a combination of clinical examination, radiological imaging (computed tomography and magnetic resonance imaging), and histopathological confirmation with immunohistochemical staining. Treatment consisted primarily of endonasal resection, with consideration of frontal craniotomy if necessary. This study aims to contribute to the understanding of paranasal schwannomas and emphasizes the importance of early detection and treatment to improve patient outcomes.<\/jats:p>","DOI":"10.1177\/01455613231195421","type":"journal-article","created":{"date-parts":[[2023,8,26]],"date-time":"2023-08-26T06:26:11Z","timestamp":1693031171000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Paranasal Schwannomas: A Comprehensive Study of 2 Cases"],"prefix":"10.1177","volume":"104","author":[{"given":"Miyu","family":"Saito","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6861-1700","authenticated-orcid":false,"given":"Takeshi","family":"Tsuda","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuya","family":"Takeda","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sho","family":"Obata","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daisuke","family":"Umeda","sequence":"additional","affiliation":[{"name":"Department of Pathology, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7952-0206","authenticated-orcid":false,"given":"Masaki","family":"Hayama","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"},{"name":"Department of Otorhinolaryngology, Hyogo Prefectural Nishinomiya Hospital, Nishinomiya City, Hyogo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eiichi","family":"Morii","sequence":"additional","affiliation":[{"name":"Department of Pathology, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidenori","family":"Inohara","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology\u2013Head and Neck Surgery, Osaka University Graduate School of Medicine, Suita City, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,8,26]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/019459989010200309"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1991.01870180113022"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0034-1544112"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2019.01.027"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/01455613211034598"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.4103\/ijabmr.ijabmr_354_22"},{"issue":"5","key":"e_1_3_3_8_2","article-title":"Sinonasal schwannoma \u2013 a case report","volume":"11","author":"Dhawle MS","year":"2017","unstructured":"Dhawle MS, Rathod SG, Bhatkule MA, Bindu RS.
