Bilateral double parotid ducts: a case report

Abstract

double parotid ducts were observed in a formalin-fixed 72-yearold male cadaver. The cadaver had no trace of scars, adhesions or signs of trauma or operation. All measurements were taken using a stainless steel caliper with an accuracy of 0.02 mm. The study conforms to the provisions of the Helsinki Declaration of 1964 and all subsequent revisions. AbstractThe parotid duct is formed by the confluence of two ducts in the gland which ascend and descend at right angle to the main duct. While crossing the masseter muscle, it can receive the accessory parotid duct. Although the anatomical course of this duct is well known, the reports on its normal anatomical variations and morphometry are very few. During routine dissection in the Department of Anatomy of Ege University School of Medicine, double parotid ducts were observed bilaterally in a 72-year-old male cadaver. These were traced carefully and neighboring anatomic structures were demonstrated. The two ducts on both sides merged with each other to form the main parotid duct that had a straight course running horizontally towards the anterior border of the masseter muscle. The length of the main parotid duct was 20.02 mm on the right side and 16 mm on the left side. The distance between tragus and the union point of the double ducts was 52 mm on the right side and 58.72 mm on the left side. Detailed morphometry and location of the double parotid ducts are useful for diagnostic and therapeutic luminal procedures.

Unilateral Duplication Of Parotid Duct. A Rare Anatomical Variation

“…Additionally, the duct may be severed by a facial laceration and is at risk of iatrogenic injury during facial surgery and injection of botulinum toxin into masseter muscle, because of its superficial location. To keep in mind the double parotid duct variation will reduce iatrogenic injury risks and improve diagnosis of parotid duct injury [19].…”
