Introduction:Sialectasis of parotid duct is an uncommon condition characterised by abnormal dilatation of a part or whole of the Stensen's duct. It may lead to recurrent parotid infections as well as a cause of concern for the patient. Superficial parotidectomy is the accepted surgical treatment for this condition. Case Report: A case of idiopathic dilatation of parotid duct is presented. It was treated by marsupialisation of the sialectatic segment.This procedure proved to be much simpler and safer than superficial parotidectomy whilst being equally effective. Conclusion: In cases of Stensen's duct sialectasis without any abnormality of the parotid gland, marsupialisation of the ectatic segment should be the treatment of choice.
