A woman in her 60s presented with left-sided clear watery otorrhoea while eating. Despite multiple consultations, diagnosis was delayed. Examination in our clinic revealed a bead of clear discharge emerging from the anterior canal wall with jaw movement. A temporal bone scan confirmed a lesion bridging the canal with the left temporomandibular joint and bulging through a dehiscence in the anterior canal wall. She was diagnosed with patent foramen of Huschke. We report the surgical management of this case, involving a left canaloplasty to reconstruct the bony defect and stop the otorrhoea. This condition should be included in the differential diagnosis of otorrhoea despite being rare. It is important to inspect the canal during jaw movement when persistent watery discharge from the ear cannot be attributed to common causes to avoid missing this diagnosis.<\/jats:p>","DOI":"10.1136\/bcr-2025-270415","type":"journal-article","created":{"date-parts":[[2026,5,22]],"date-time":"2026-05-22T15:40:21Z","timestamp":1779464421000},"page":"e270415","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Patent foramen of Huschke causing persistent otorrhoea"],"prefix":"10.1136","volume":"19","author":[{"given":"Alveena","family":"Farid","sequence":"first","affiliation":[{"name":"Otorhinolaryngology, Calderdale and Huddersfield NHS Foundation Trust, Huddersfield, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dipan","family":"Mistry","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Calderdale and Huddersfield NHS Foundation Trust, Huddersfield, England, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2026,5,22]]},"reference":[{"key":"2026052208401093000_19.5.e270415.1","doi-asserted-by":"crossref","first-page":"111","DOI":"10.5005\/jp-journals-10003-1552","article-title":"Patent Foramen of Huschke: An Atypical Cause of Masticatory Tinnitus","volume":"16","author":"Bajpai","year":"2025","journal-title":"An International Journal of Otorhinolaryngology Clinics"},{"key":"2026052208401093000_19.5.e270415.2","first-page":"1317","article-title":"Foramen tympanicum, or foramen of huschke: Pathologic cases and anatomic ct study","volume":"26","author":"Lacout","year":"2005","journal-title":"American Journal of Neuroradiology"},{"key":"2026052208401093000_19.5.e270415.3","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1016\/j.amsu.2017.04.020","article-title":"Spontaneous temporomandibular joint herniation into the external auditory canal through a patent foramen of Huschke: A case report","volume":"18","author":"Ryu","year":"2017","journal-title":"Ann Med Surg (Lond)"},{"key":"2026052208401093000_19.5.e270415.4","doi-asserted-by":"crossref","first-page":"92","DOI":"10.1080\/08998280.2017.11929544","article-title":"Identification of Foramen of Huschke with Reversible Herniation of Temporomandibular Joint Soft Tissue Into the External Auditory Canal on Multidetector Computed Tomography","volume":"30","author":"Mittal","year":"2017","journal-title":"Baylor University Medical Center Proceedings"},{"key":"2026052208401093000_19.5.e270415.5","doi-asserted-by":"publisher","DOI":"10.7874\/kja.2013.17.2.90"},{"key":"2026052208401093000_19.5.e270415.6","doi-asserted-by":"crossref","first-page":"791","DOI":"10.1007\/s00405-020-06296-x","article-title":"Prevalence of foramen Huschke: evaluation of the association between mastoid pneumatization volume and the existence of foramen Huschke using cone beam computed tomography","volume":"278","author":"Ko\u00e7","year":"2021","journal-title":"Eur Arch Otorhinolaryngol"},{"key":"2026052208401093000_19.5.e270415.7","doi-asserted-by":"crossref","unstructured":"Pazardzhikliev D , Kraeva M , Uchikov P .
