Minor salivary gland5

• Necrotizing sialometaplasia is a lesion that usually arises from a minor salivary gland on the palate. (wikipedia.org)
• they are usually associated with the sublingual gland, and less often they arise from the submandibular gland or a minor salivary gland. (wikipedia.org)
• Mucoceles, which are of minor salivary gland origin, are also referred to as mucus retention phenomenon and mucus escape reaction. (medscape.com)
• such insults include a crush-type injury and/or severance of the excretory duct of the minor salivary gland. (medscape.com)
• Changes in minor salivary gland function and composition of the saliva may contribute to their development. (medscape.com)

Major salivary glands2

• There are three paired major salivary glands in humans: the parotid glands, the submandibular glands, and the sublingual glands. (wikipedia.org)
• Ranulas are mucoceles that occur in the floor of the mouth and usually involve the major salivary glands. (medscape.com)

Submandibular gland3

• The submandibular gland is medial to the angle of the mandible, and it drains its mixture of serous and mucous saliva via the submandibular duct (Wharton duct) into the mouth, usually opening in a punctum in the floor of mouth. (wikipedia.org)
• Rarely, the mucocele arises within the submandibular gland and presents as a plunging ranula. (medscape.com)
• Although most oral ranulas originate from the secretions of the sublingual gland, they may develop from the secretions of the submandibular gland duct or the minor salivary glands on the floor of the mouth. (medscape.com)

Duct5

• Oral mucoceles are common, and are caused by rupture of a salivary gland duct and spillage of mucin into the surrounding tissues. (wikipedia.org)
• These lesions occur as the result of trauma or obstruction to the salivary gland excretory duct and spillage of mucin into the surrounding soft tissues. (medscape.com)
• At times, the mucus retention cyst, also referred to as the sialocyst or the salivary duct cyst, is included in this group of lesions but appears to represent a separate entity on the basis of its clinical and histopathologic features. (medscape.com)
• The disruption of the excretory duct results in extravasation of mucus from the gland into the surrounding soft tissue. (medscape.com)
• In many cases, mucosal inflammation that involves the minor gland duct results in blockage, dilatation, and rupture of the duct with subepithelial spillage of fluid. (medscape.com)

Sublingual glands1

• Occasionally, ectopic sublingual glands may be responsible for the problem. (medscape.com)

Lobules2

• It is thought to be due to vascular infarction of the salivary gland lobules. (wikipedia.org)
• Furthermore, trauma that results in damage to the glandular parenchymal cells in the salivary gland lobules is another potential mechanism. (medscape.com)

Mucus extravasation1

• The mucus extravasation of the sublingual gland almost exclusively causes cervical ranulas. (medscape.com)

Ectopic2

• They include: Aplasia Atresia Ectopic salivary gland tissue Stafne defect - an uncommon condition which some consider to be an anatomic variant rather than a true disease. (wikipedia.org)
• It is thought to be created by an ectopic portion of salivary gland tissue which causes the bone of the mandible to remodel around the tissue, creating an apparent cyst like radiolucent area on radiographs. (wikipedia.org)

Ranula2

• Specifically, the ranula originates in the body of the sublingual gland, in the ducts of Rivini of the sublingual gland, and, infrequently from the minor salivary glands at this location. (medscape.com)
• Oral and cervical ranulas require complete excision of the oral portion of the ranula, in addition to the responsible gland. (medscape.com)

Rarely1

• Infections involving the salivary glands can be viral or bacterial (or rarely fungal). (wikipedia.org)

Inflammation1

• Sialadenitis is inflammation of a salivary gland, usually caused by infections, although there are other, less common causes of inflammation, such as irradiation, allergic reactions, and trauma. (wikipedia.org)

Mucoceles2

• Mucoceles usually require excisional biopsy and removal of the servicing minor salivary glands. (medscape.com)
• The development of mucoceles and ranulas depend on the disruption of the flow of saliva from the secretory apparatus of the salivary glands. (medscape.com)

Excision1

• if it is larger and causing symptoms, excision of the sublingual gland may be indicated. (wikipedia.org)

Function1

• The function of the salivary glands is to secrete saliva, which has a lubricating function, which protects the mucosa of the mouth during eating and speaking. (wikipedia.org)

Flow2

• Salivary gland dysfunction affects the flow, amount, or quality of saliva produced. (wikipedia.org)
• Risk factors include reduced salivary flow. (wikipedia.org)

Obstruction1

• Mucus retention cyst is formed markedly by obstruction of salivary ductal walls causing dilatation of ducts without spillage of mucin. (pioon.com)

Ducts2

• The parotid glands are in front of the ears, one on side, and secrete mostly serous saliva, via the parotid ducts (Stenson ducts), into the mouth, usually opening roughly opposite the second upper molars. (wikipedia.org)
• Specifically, the ranula originates in the body of the sublingual gland, in the ducts of Rivini of the sublingual gland, and, infrequently from the minor salivary glands at this location. (medscape.com)

Mucosa3

• There are also about 800-1,000 minor salivary glands in the mucosa of the mouth. (wikipedia.org)
• The function of the salivary glands is to secrete saliva, which has a lubricating function, which protects the mucosa of the mouth during eating and speaking. (wikipedia.org)
• Mucocele is one of the common lesion of oral mucosa encountered that results from an alteration of minor salivary glands. (sbvjournals.com)

Mucocele1

• Mucocele of the minor salivary glands in an infant: treatment with diode laser. (pioon.com)

Trauma1

• Sialadenitis is inflammation of a salivary gland, usually caused by infections, although there are other, less common causes of inflammation, such as irradiation, allergic reactions, and trauma. (wikipedia.org)

Diseases1

• Salivary gland diseases (SGDs) are multiple and varied in cause. (wikipedia.org)
