IntroductionParotid duct sialocele is a salivary cavity arising at the expense of the parotid duct. Many cases of parotid sialocele have been published, but very few cases of parotid duct sialocele have been reported.Case ReportWe report a case of post-traumatic parotid duct sialocele that was assessed by MR sialography. The parotid duct was catheterized via the oral cavity and the catheter was left in place for ten days. No recurrence was observed.DiscussionPublished cases of parotid duct sialocele are rare, as only seven cases were identified in the literature. Several treatment options are available for sialocele involving the parotid gland or parotid duct. Subcutaneous injection of botulinum toxin is commonly used, with good results. Parotid duct catheterization has also been reported, mainly for parotid gland sialoceles. To the best of our knowledge, apart from the present case, the use of this technique for parotid duct sialocele has only been reported once before. This technique is minimally invasive, with very low morbidity and good results.Copyright © 2014 Elsevier Masson SAS. All rights reserved.
