These tracts are often initially misdiagnosed unless the treating clinician considers a dental aetiology. This case report of a 19-year-old woman describes the diagnosis and treatment of an extraoral cutaneous sinus tract of odontogenic origin. Non-surgical conservative endodontic therapy was opted as the involved teeth were restorable. One month after the completion of obturation, there was closure of the sinus tract. One year follow-up showed complete resolution of the sinus tract with minimal scar formation.<\/jats:p>","DOI":"10.1136\/bcr-2020-234699","type":"journal-article","created":{"date-parts":[[2020,7,21]],"date-time":"2020-07-21T02:05:20Z","timestamp":1595297120000},"page":"e234699","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Non-surgical management of an extraoral cutaneous sinus tract of odontogenic origin"],"prefix":"10.1136","volume":"13","author":[{"given":"Lynn Lilly","family":"Varghese","sequence":"first","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, Melaka Manipal Medical College, Bukit Baru, Melaka, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Auric","family":"Bhattacharya","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, Melaka Manipal Medical College, Bukit Baru, Melaka, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Praveena","family":"Sharma","sequence":"additional","affiliation":[{"name":"Department of Conservative Dentistry and Endodontics, College of Dental Sciences, Davangere, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abhishek","family":"Apratim","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, Melaka Manipal Medical College, Bukit Baru, Melaka, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,7,20]]},"reference":[{"key":"2025082709082916000_13.7.e234699.1","doi-asserted-by":"crossref","first-page":"841","DOI":"10.1097\/00004770-200312000-00015","article-title":"Extraoral sinus tract misdiagnosed as an endodontic lesion","volume":"29","author":"Cohenca","year":"2003","journal-title":"J Endod"},{"key":"2025082709082916000_13.7.e234699.2","first-page":"264","article-title":"Cutaneous dental sinus tract, a common misdiagnosis: a case report and review of the literature","volume":"70","author":"Cantatore","year":"2002","journal-title":"Cutis"},{"key":"2025082709082916000_13.7.e234699.3","doi-asserted-by":"crossref","first-page":"S76","DOI":"10.4103\/0970-4388.43537","article-title":"Diagnosis and treatment of mandibular extraoral sinus of periodontal origin in a 9-year-old boy: a case report","volume":"26","author":"Ozdemir","year":"2008","journal-title":"J Indian Soc Pedod Prev Dent"},{"key":"2025082709082916000_13.7.e234699.4","doi-asserted-by":"publisher","DOI":"10.1016\/S0190-9622(86)70012-1"},{"key":"2025082709082916000_13.7.e234699.5","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(88)90384-2"},{"key":"2025082709082916000_13.7.e234699.6","doi-asserted-by":"crossref","first-page":"410","DOI":"10.1111\/j.1525-1470.2010.01187.x","article-title":"Cutaneous facial sinus tract of dental origin","volume":"27","author":"Mardones","year":"2010","journal-title":"Pediatr Dermatol"},{"key":"2025082709082916000_13.7.e234699.7","doi-asserted-by":"publisher","DOI":"10.1097\/00004770-200407000-00019"},{"key":"2025082709082916000_13.7.e234699.8","doi-asserted-by":"crossref","first-page":"593","DOI":"10.1016\/S0099-2399(06)81130-1","article-title":"Cutaneous sinus tract caused by vertical root fracture","volume":"23","author":"Chan","year":"1997","journal-title":"J Endod"},{"key":"2025082709082916000_13.7.e234699.9","doi-asserted-by":"crossref","unstructured":"Mishra R , Khan TS .
