While antrochoanal polyps predominate the literature, the lesser known sphenochoanal polyp is equally as bothersome. To our knowledge, no prior dedicated review exists that characterises the patient population affected by this disease. We present a case and associated literature review over the past 30 years on the patient demographics and treatment of sphenochoanal polyps. A total of 88 cases were identified. Of the published cases, 77 were included in our search as patient characteristics were available. The age ranged from 2 to 80 years old. There were 35 female and 42 male patients. Only 58 studies established laterality, with the polyps originating from the left in 32 cases, right in 25 and bilateral in 1 case. Sphenochoanal polyps occur in all ages, nearly even distribution across sex. Endoscopic removal is safe with favourable outcomes.<\/jats:p>","DOI":"10.1136\/bcr-2022-251182","type":"journal-article","created":{"date-parts":[[2023,5,2]],"date-time":"2023-05-02T11:00:28Z","timestamp":1683025228000},"page":"e251182","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Sphenochoanal polyps"],"prefix":"10.1136","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7721-4697","authenticated-orcid":false,"given":"Leith","family":"Bayazid","sequence":"first","affiliation":[{"name":"Department of Otolaryngology, University of South Florida, Tampa, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gary D","family":"Josephson","sequence":"additional","affiliation":[{"name":"Department of Pediatric Otolaryngology, Nemours Children's Clinic, Jacksonville, Florida, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,5,2]]},"reference":[{"key":"2025082713074876000_16.5.e251182.1","doi-asserted-by":"crossref","first-page":"365","DOI":"10.1097\/00004728-198903000-00042","article-title":"Sphenochoanal polyp: CT findings","volume":"13","author":"Hayes","year":"1989","journal-title":"J Comput Assist Tomogr"},{"key":"2025082713074876000_16.5.e251182.2","doi-asserted-by":"crossref","first-page":"138","DOI":"10.1007\/s004050050030","article-title":"Clinical presentation of a sphenochoanal polyp","volume":"255","author":"\u0130leri","year":"1998","journal-title":"Eur Arch Oto-Rhino-Laryngol"},{"key":"2025082713074876000_16.5.e251182.3","first-page":"311","article-title":"Sphenochoanal polyp: current diagnosis and management","volume":"89","author":"Al-Qudah","year":"2010","journal-title":"Ear Nose Throat J"},{"key":"2025082713074876000_16.5.e251182.4","doi-asserted-by":"crossref","first-page":"101263","DOI":"10.1016\/j.epsc.2019.101263","article-title":"Sphenochoanal polyp causing obstruction","volume":"48","author":"Pol","year":"2019","journal-title":"J Pediatr Surg Case Rep"},{"key":"2025082713074876000_16.5.e251182.5","doi-asserted-by":"crossref","first-page":"S153","DOI":"10.1542\/peds.2012-0055I","article-title":"Standard 6: age groups for pediatric trials","volume":"129 Suppl 3","author":"Williams","year":"2012","journal-title":"Pediatrics"},{"key":"2025082713074876000_16.5.e251182.6","doi-asserted-by":"publisher","DOI":"10.1007\/s003300000565"},{"key":"2025082713074876000_16.5.e251182.7","first-page":"43","article-title":"Sphenochoanal polyp in children.
