In this article, we report the case of a 63-year-old male patient with persistent nasal obstruction on the right side. An irregular light yellow lobulated mass with smooth surface could be visualized in the nasal cavity through nasal endoscopy, arising from the right nasal septum and extending to the nasopharynx. Computed tomography scan showed a large soft tissue shadow of the nasal meatus, with ossified structure in the center. Histopathological biopsy revealed nasopharyngeal mucositis. The patient underwent functional endoscopic sinus surgery and the polypoidal mass sent for histopathological examination proved to be choanal polyps.<\/jats:p>","DOI":"10.1177\/01455613241234249","type":"journal-article","created":{"date-parts":[[2024,3,6]],"date-time":"2024-03-06T00:58:24Z","timestamp":1709686704000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Choanal Polyps With Osseous Metaplasia From the Nasal Septum: A Case Report and the Literature Review"],"prefix":"10.1177","volume":"105","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7194-5202","authenticated-orcid":false,"given":"Hongjin","family":"Li","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Xijing Hospital, Air Force Military Medical University, Xi\u2019an, Shaanxi, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiawei","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Xijing Hospital, Air Force Military Medical University, Xi\u2019an, Shaanxi, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yucong","family":"Du","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Xijing Hospital, Air Force Military Medical University, Xi\u2019an, Shaanxi, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Xijing Hospital, Air Force Military Medical University, Xi\u2019an, Shaanxi, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaodong","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Xijing Hospital, Air Force Military Medical University, Xi\u2019an, Shaanxi, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dingjun","family":"Zha","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery, Xijing Hospital, Air Force Military Medical University, Xi\u2019an, Shaanxi, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,3,5]]},"reference":[{"issue":"2","key":"e_1_3_2_2_2","first-page":"79","article-title":"Choanal polyps: one entity, one surgical approach","volume":"35","author":"Lopatin A","year":"1997","unstructured":"Lopatin A, Bykova V, Piskunov GJR.
