Right parotid gland. Deep and anterior aspects. (Parotid duct labeled at center right.)
Dissection, showing salivary glands of right side. (Parotid duct visible at center.)
The average dimensions of the parotid duct are 5 cm long and 3 mm wide although it is narrower at its oral orifice. It begins by the confluence of two main tributaries within the anterior part of the parotid gland: the duct appears at the anterior border of the upper part of the gland and passes horizontally across masseter, approximately midway between the angle of the mouth and the zygomatic arch. It passes through the buccal fat, buccopharyngeal fascia, and buccinator muscle then opens into the vestibule of the mouth across from the maxillary second molar tooth on the inner surface of the buccal mucosa at the parotid papilla. The buccinator acts as a valve that prevents inflation of the duct during blowing. Running along with the duct superiorly is the transverse facial artery and upper buccal nerve; running along with the duct inferiorly is the lower buccal nerve.
