What is submandibular Sialoadenectomy?
Submandibular sialoadenectomy is a common head and neck procedure. Indications include the presence of benign and malignant tumors and inflammatory disease with or without intraglandular sialolithiasis. The standard technique involves a variably sized incision.
What wraps around submandibular duct?
The lingual nerve crosses the submandibular duct inferiorly beneath the sublingual gland. The blood supply to the floor of mouth is excellent, the lingual artery and vein lying medial to the sublingual gland.
What is the Wharton’s duct?
Wharton’s duct is a thin tube, about 5 cm in length, and an essential carrier of your saliva. Each submandibular duct begins at the right and left sides of the mouth. The submandibular duct openings are underneath the tongue. These openings that empty into the oral cavity are also known as sublingual caruncles.
What is the function of Wharton’s duct?
The submandibular duct or Wharton duct or submaxillary duct, is one of the salivary excretory ducts. It is about 5 cm. long, and its wall is much thinner than that of the parotid duct. It drains saliva from each bilateral submandibular gland and sublingual gland to the sublingual caruncle at the base of the tongue.
Can the submandibular gland be removed?
Submandibular gland removal is surgery to take out a saliva gland below the lower jaw. The gland may have been removed because of infection, a tumour, or a blocked saliva duct.
What does submandibular ganglion do?
The submandibular ganglion (SMG) is a parasympathetic ganglion, which receives inputs from preganglionic cholinergic neurons and innervates the submandibular salivary gland to control saliva secretion.
What nerve passes through submandibular gland?
The submandibular glands receive their parasympathetic input via the chorda tympani nerve, which is a branch of the facial nerve via the submandibular ganglion.
Which duct open with or near the submandibular duct?
parotid duct (Stenson duct): connects the parotid gland to the buccal mucosa, adjacent to maxillary second molar. submandibular duct (Wharton duct): connects the submandibular gland to the floor of the mouth.
What is the treatment of submandibular duct calculi?
The classic treatment of sialolithiasis is antibiotics and anti-inflammatory agents, hoping for a spontaneous stone expression through the papilla. In cases of submandibular stones located close to Wharton papillae, a marsupialization (sialodochoplasty) is performed and the stone removed.
Is submandibular gland removal painful?
The area below your jaw may be sore for several days after your surgery. The area also may be slightly swollen or bruised. It will probably take 1 to 2 weeks for the cut (incision) to heal.
Where is the duct of the submandibular gland located?
The duct extends anteriorly from the submandibular gland superior to the lingual nerve and submandibular ganglion curving over the posterior edge of the mylohyoid muscle into the sublingual space.
Why do we use submandibular approach in cadavers?
This approach allows better manipulation of the fragments, good control of the lingual cortex and inferior border, and application of selected hardware. Here we demonstrate how to perform a submandibular approach in a cadaver.
When to use surgical excision of the submandibular gland?
Surgical excision of the submandibular gland (SMG) is commonly indicated in patients with neoplasms, and non-neoplastic conditions such as chronic sialadenitis, sialolithiasis, ranula and drooling.
Where does saliva go after the submandibular gland?
The submandibular duct (also known as Wharton’s duct) allows the passage of saliva from the submandibular gland to the sublingual papilla located anteriorly.
