An early 30s man presented with a decade-long history of severe left-sided chronic facial pain (CFP). Multiple prior treatments resulted in an edentulous patient with persistent pain. Imaging revealed a dome-shaped radiopaque change in the left maxillary sinus. History and clinical examination suggested persistent idiopathic facial pain, and doubts about the outcome of a surgical intervention were explained to the patient. Surgical removal of the MRC via lateral antrotomy led to complete symptom resolution of CFP. This case substantiates the importance of considering MRCs as a possible cause of CFP. It also emphasises the need for a systematic multidisciplinary approach in cases of unexplained CFP.<\/jats:p>","DOI":"10.1136\/bcr-2024-259924","type":"journal-article","created":{"date-parts":[[2024,4,29]],"date-time":"2024-04-29T13:50:47Z","timestamp":1714398647000},"page":"e259924","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Severe facial pain and removal of maxillary sinus mucous retention cyst"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-5422-1434","authenticated-orcid":false,"given":"Matija","family":"Bozovi\u010dar","sequence":"first","affiliation":[{"name":"Dentist, MB2 zobozdravstvena dejavnost, Matija Bozovi\u010dar s.p, \u0160kofja Loka, Slovenia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8703-3048","authenticated-orcid":false,"given":"Marko","family":"Bo\u017ei\u010d","sequence":"additional","affiliation":[{"name":"Surgery, OMF kirurgija Marko Bo\u017ei\u010d, s.p, Celje, Slovenia"},{"name":"Medicinska fakulteta, Univerza v Mariboru, Maribor, Slovenia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,4,29]]},"reference":[{"key":"2025082710523592000_17.4.e259924.1","doi-asserted-by":"crossref","first-page":"766","DOI":"10.1002\/alr.21177","article-title":"Cysts of the maxillary sinus: a literature review","volume":"3","author":"Giotakis","year":"2013","journal-title":"Int Forum Allergy Rhinol"},{"key":"2025082710523592000_17.4.e259924.2","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(86)90317-8"},{"key":"2025082710523592000_17.4.e259924.3","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(84)90080-X"},{"key":"2025082710523592000_17.4.e259924.4","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(81)90118-3"},{"key":"2025082710523592000_17.4.e259924.5","doi-asserted-by":"publisher","DOI":"10.3109\/00016488909125554"},{"key":"2025082710523592000_17.4.e259924.6","doi-asserted-by":"crossref","first-page":"1904","DOI":"10.1002\/lary.21040","article-title":"Symptomatic maxillary sinus retention cysts: should they be removed","volume":"120","author":"Albu","year":"2010","journal-title":"Laryngoscope"},{"key":"2025082710523592000_17.4.e259924.7","doi-asserted-by":"crossref","first-page":"226","DOI":"10.3342\/ceo.2014.7.3.226","article-title":"Maxillary sinus retention cysts protruding into the inferior Meatus","volume":"7","author":"Hong","year":"2014","journal-title":"Clin Exp Otorhinolaryngol"},{"key":"2025082710523592000_17.4.e259924.8","doi-asserted-by":"crossref","first-page":"162","DOI":"10.5152\/tao.2017.2759","article-title":"Paranasal sinus anatomic variations accompanying maxillary sinus retention cysts: a radiological analysis","volume":"55","author":"Arslan","year":"2017","journal-title":"Turk Arch Otorhinolaryngol"},{"key":"2025082710523592000_17.4.e259924.9","doi-asserted-by":"publisher","DOI":"10.1097\/01.mlg.0000250777.52882.7a"},{"key":"2025082710523592000_17.4.e259924.10","doi-asserted-by":"crossref","first-page":"e276","DOI":"10.4317\/medoral.24155","article-title":"Are Mucous retention cysts and pseudocysts in the maxillary sinus a risk factor for dental implants?
