Maxillary sinus involvement is exceedingly rare, and association with an ectopic third molar located near the sinus roof is rarer still. A 26-year-old female presented with vague midfacial fullness and an unerupted maxillary third molar. Panoramic radiography and CBCT revealed an ectopic 18 near the superior sinus wall enveloped by a well-defined radiolucent lesion of higher soft-tissue density than typical dentigerous cysts. The lesion showed scalloped borders, cortical thinning, and anteroposterior spread, suggestive of OKC. Complete enucleation with peripheral ostectomy via a Caldwell\u2013Luc antrostomy was performed, along with removal of the ectopic molar. Healing was uneventful. Histopathology confirmed OKC. This case broadens the limited documentation of OKC in the sinus roof region and highlights the need for long-term follow-up given its recurrence profile.<\/jats:p>","DOI":"10.4103\/ijdr.ijdr_117_26","type":"journal-article","created":{"date-parts":[[2026,6,4]],"date-time":"2026-06-04T09:00:07Z","timestamp":1780563607000},"page":"107-110","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Ectopic Maxillary Third Molar with a Large Odontogenic Keratocyst in Roof of Maxillary Sinus - A Case Report"],"prefix":"10.4103","volume":"37","author":[{"given":"S.M.","family":"Balaji","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Balaji Dental and Craniofacial Hospital, Teynampet, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Preetha","family":"Balaji","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Balaji Dental and Craniofacial Hospital, Teynampet, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,6,1]]},"reference":[{"issue":"4","key":"R1-20260618","article-title":"Maxillary odontogenic keratocyst","author":"Walsh","year":"2022","journal-title":"Journal of Surgical Case Reports 2022"},{"key":"R2-20260618","article-title":"A Rare Presentation of Follicular Odontogenic Keratocyst of Maxillary Sinus Mimicking Dentigerous Cyst: A Case Report with 3-Year-Follow-Up","author":"Chandran","year":"2025","journal-title":"Journal of Dentistry"},{"issue":"(4)","key":"R3-20260618","article-title":"An unusual case of maxillary sinus odontogenic keratocyst: an insightful report with review of the literature","volume":"15","author":"Singh","year":"2023","journal-title":"Cureus"},{"key":"R4-20260618","doi-asserted-by":"crossref","first-page":"183","DOI":"10.4103\/ijabmr.ijabmr_4_23","article-title":"Ectopic tooth with odontogenic keratocyst in myasthenia gravis: a rare coexistence","volume":"13","author":"Winnifred","year":"2023","journal-title":"International Journal of Applied and Basic Medical Research"},{"key":"R5-20260618","doi-asserted-by":"crossref","first-page":"132","DOI":"10.1016\/j.ijscr.2020.05.003","article-title":"A rare case of odontogenic keratocyst extending into the sphenoid bone from the maxilla","volume":"71","author":"Goto","year":"2020","journal-title":"International Journal of Surgery Case Reports"},{"key":"R6-20260618","first-page":"59","article-title":"Keratocystic odontogenic tumor associated with impacted maxillary third molar extending to the antrum: A challenging diagnosis","volume":"15","author":"Pahlevan","year":"2019","journal-title":"Human Pathology: Case Reports"},{"issue":"(Suppl 1)","key":"R7-20260618","doi-asserted-by":"crossref","first-page":"74","DOI":"10.4103\/jomfp.JOMFP_319_18","article-title":"Odontogenic keratocyst arising in the maxillary sinus: A rare case report","volume":"23","author":"Sheethal","year":"2019","journal-title":"Journal of Oral and Maxillofacial Pathology"},{"key":"R8-20260618","doi-asserted-by":"crossref","first-page":"1854","DOI":"10.1002\/ccr3.1714","article-title":"Third molar in the orbital floor: A precarious presentation of odontogenic keratocyst\u2014A case report and review of literature","volume":"6","author":"Shetty","year":"2018","journal-title":"Clinical Case Reports"},{"key":"R9-20260618","doi-asserted-by":"crossref","first-page":"658","DOI":"10.3390\/antibiotics11050658","article-title":"Transinusal pathway removal of an impacted third molar with an unusual approach: A case report and a systematic review of the literature","volume":"11","author":"Mavriqi","year":"2022","journal-title":"Antibiotics"}],"container-title":["Indian Journal of Dental Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/ijdr.ijdr_117_26","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T18:30:46Z","timestamp":1787769046000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/ijdr.ijdr_117_26"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":9,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.4103\/ijdr.ijdr_117_26","relation":{},"ISSN":["0970-9290","1998-3603"],"issn-type":[{"value":"0970-9290","type":"print"},{"value":"1998-3603","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"2026-02-08","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-05-18","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
