We report the case of a patient submitted to stapedectomy who, 4\u2009weeks later, suddenly developed right hearing loss, ipsilateral tinnitus and vertigo. On the physical examination, the patient showed no signs of vestibular deficits. Audiometry was compatible with right profound mixed hearing loss and high-resolution CT of the temporal bone revealed the presence of pneumolabyrinth. During exploratory tympanotomy, the prosthesis was found dislodged; the communication between the middle and inner ear was closed with vein graft and a new prosthesis was placed. Following surgery, vestibular symptoms was abolished and the patient experienced great improvement of the hearing thresholds.<\/jats:p>","DOI":"10.1136\/bcr-2019-232190","type":"journal-article","created":{"date-parts":[[2019,11,5]],"date-time":"2019-11-05T07:25:59Z","timestamp":1572938759000},"page":"e232190","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Pneumolabyrinth: a rare complication of stapes surgery"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1039-2525","authenticated-orcid":false,"given":"Patricia S","family":"Gomes","sequence":"first","affiliation":[{"name":"Otorhinolaryngology, Hospital da Senhora da Oliveira Guimar\u00e3es, Guimaraes, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergio","family":"Caselhos","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Hospital da Senhora da Oliveira Guimar\u00e3es, Guimaraes, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Teresa","family":"Vide","sequence":"additional","affiliation":[{"name":"Neuroradiology, Hospital da Senhora da Oliveira Guimar\u00e3es, Guimaraes, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rui","family":"Fonseca","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Hospital da Senhora da Oliveira Guimar\u00e3es, Guimaraes, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,11,4]]},"reference":[{"key":"2025082723545741000_12.11.e232190.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2010.12.010"},{"key":"2025082723545741000_12.11.e232190.2","doi-asserted-by":"crossref","first-page":"750","DOI":"10.1177\/014556130108001014","article-title":"Pneumolabyrinth: a late complication of stapes surgery","volume":"80","author":"Scheid","year":"2001","journal-title":"Ear Nose Throat J"},{"key":"2025082723545741000_12.11.e232190.3","doi-asserted-by":"crossref","first-page":"361","DOI":"10.1016\/j.anorl.2015.10.005","article-title":"Late pneumolabyrinth after stapedectomy","volume":"133","author":"Ziade","year":"2016","journal-title":"Eur Ann Otorhinolaryngol Head Neck Dis"},{"key":"2025082723545741000_12.11.e232190.4","first-page":"374","article-title":"Pneumolabyrinth: a new radiologic sign for fracture of the stapes footplate","volume":"5","author":"Mafee","year":"1984","journal-title":"Am J Otol"},{"key":"2025082723545741000_12.11.e232190.5","doi-asserted-by":"crossref","first-page":"639","DOI":"10.1097\/MAO.0b013e31828be1ab","article-title":"Early computed tomography findings of the inner ear after stapes surgery and its clinical correlations","volume":"34","author":"Bajin","year":"2013","journal-title":"Otol Neurotol"},{"key":"2025082723545741000_12.11.e232190.6","doi-asserted-by":"publisher","DOI":"10.1097\/00004424-199512000-00004"},{"key":"2025082723545741000_12.11.e232190.7","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjoto.2008.07.010"},{"key":"2025082723545741000_12.11.e232190.8","doi-asserted-by":"publisher","DOI":"10.3109\/00016489309135892"},{"key":"2025082723545741000_12.11.e232190.9","first-page":"430","article-title":"Role of air bubbles in the perilymph as a cause of sudden deafness","volume":"7","author":"Nishioka","year":"1986","journal-title":"Am J Otol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-232190","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T06:55:09Z","timestamp":1756364109000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-232190"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,11]]},"references-count":9,"journal-issue":{"issue":"11","published-online":{"date-parts":[[2019,11,4]]},"published-print":{"date-parts":[[2019,11]]}},"alternative-id":["10.1136\/bcr-2019-232190"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-232190","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2019,11]]}}}
