The parotid duct or Stensen duct is a salivary duct. It is the route that saliva takes from the major salivary gland, the parotid gland, into the mouth. [1] It opens into the mouth opposite the second upper molar tooth.

2024年10月30日 · The parotid duct, also known as Stensen duct, drains saliva from the parotid gland into the oral cavity. Following confluence of two main tributaries within the parotid gland, the duct emerges anteriorly from its substance through the adjacent buccal fat, superficial to the masseter muscle over which it passes horizontally 9.

Your parotid gland connects to a tube (called Stensen’s duct) that carries saliva to your mouth, releasing near your upper molar teeth. Your sublingual and submandibular glands connect to a tube (called Wharton’s duct) that transports saliva to the floor of your mouth (under your tongue).

2023年8月3日 · Two major ducts arising from the parotid gland unite within the substance of the organ to form the parotid duct of Stensen. The parotid duct is approximately 7 cm x 3 mm long and leaves the superior part of the anteromedial surface of the gland.

The parotid duct, a long excretory duct, emerges from the front of each gland, superficial to the masseter muscle. The duct pierces the buccinator muscle, then opens into the mouth on the inner surface of the cheek, usually opposite the maxillary second molar.

2024年3月7日 · The parotid duct, also known as the Stensen duct, is the 5-7 cm long salivary duct of the parotid gland. It is formed within the parotid gland from two main tributaries and then exits the gland from its anteromedial surface.

2024年8月29日 · The secretions of the parotid gland are transported to the oral cavity by the Stensen duct. It arises from the anterior surface of the gland, traversing the masseter muscle. The duct then pierces the buccinator, moving medially. It opens out into the oral cavity near the second upper molar.

2024年9月10日 · The parotid main excretory duct (Stensen duct) projects from the anterior portion of the superficial lobe and runs over the masseter muscle until it reaches its anterior border, from where it turns medially to penetrate the buccinator muscle [1]. This opens into the buccal cavity at the level of the buccal mucosa of the maxillary second molar. [1]

2025年1月24日 · The excretory duct of the parotid gland is known as Stensen’s duct: It originates from the deep lobe of the parotid gland. The duct passes horizontally, over the masseter muscle, and enters the buccal mucosa (the lining of the cheek). It opens into the oral cavity opposite the second upper molar at the parotid papilla.
