It was managed as a parotid infection but recurred and a draining pre-auricular sinus developed, which was thought to be a parotid fistula. This was managed by cautery, followed by excision of the fistula, both of which were unsuccessful. Following this, further investigations revealed that the cause of the facial sinus was in fact a cyst associated with a mandibular fourth molar in the posterior ascending ramus. The tooth was extracted, via a pre-auricular extra-oral approach, under general anaesthetic. <\/jats:p><jats:p> Clinical Relevance: This case shows how a dental panoramic radiograph can be extremely helpful at ruling out certain pathology. It also demonstrates how the symptoms of an infection arising from a tooth in the ramus may be misdiagnosed as salivary gland pathology. <\/jats:p>","DOI":"10.12968\/denu.2013.40.4.343","type":"journal-article","created":{"date-parts":[[2017,8,1]],"date-time":"2017-08-01T10:23:23Z","timestamp":1501583003000},"page":"343-345","source":"Crossref","is-referenced-by-count":7,"title":["Parotid fistula \u2013 an extra-orally draining infected dentigerous cyst associated with a supernumerary fourth molar in ascending ramus"],"prefix":"10.12968","volume":"40","author":[{"given":"Ripponjit Kaur","family":"Sanghera","sequence":"first","affiliation":[{"name":"Locum Specialty Doctor, Oral and Maxillofacial Surgery, Broomfield Hospital, Mid Essex NHS Trust, Essex"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Judith","family":"Jones","sequence":"additional","affiliation":[{"name":"Senior Clinical Lecturer\/ Honorary Consultant in Oral Surgery, Barts and London School of Medicine and Dentistry, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"5130","reference":[{"key":"B1","first-page":"174","volume":"25","author":"Marchese-Ragona R","year":"2005","journal-title":"Acta Otorhinolaryngol Ital"},{"key":"B2","doi-asserted-by":"crossref","first-page":"249","DOI":"10.1186\/1752-1947-4-249","volume":"4","author":"Naragund AI","year":"2010","journal-title":"J Med Case Reports"},{"issue":"4","key":"B3","doi-asserted-by":"crossref","first-page":"224","DOI":"10.4248\/IJOS09056","volume":"1","author":"Ferreira-Junior O","year":"2009","journal-title":"Int J Oral Science"},{"key":"B4","first-page":"233","volume":"26","author":"Giancotti A","year":"2002","journal-title":"J Clin Pediatr Dent"},{"key":"B5","volume-title":"Essentials of Oral Pathology and Oral Medicine","author":"Cawson RA","year":"1998","edition":"6"},{"key":"B6","doi-asserted-by":"crossref","first-page":"e15","DOI":"10.1016\/j.tripleo.2009.02.002","volume":"107","author":"McCrea S.","year":"2009","journal-title":"Oral Surg Oral Med Oral Pathol Oral Radiol Endod"},{"key":"B7","volume-title":"Oral and Maxillofacial Pathology","author":"Neville BW","year":"2002","edition":"2"},{"key":"B8","doi-asserted-by":"crossref","first-page":"630","DOI":"10.1016\/0278-2391(94)90105-8","volume":"52","author":"Pasquale B","year":"1994","journal-title":"J Oral Maxillofac Surg"},{"journal-title":"Guidance Notes for Dental Practitioners on the Safe Use of X-Ray Equipment","first-page":"1","year":"2001","key":"B9"},{"key":"B10","unstructured":"Som PM, Curtin H.
