Читать книгу Shear's Cysts of the Oral and Maxillofacial Regions - Paul M. Speight - Страница 21

Cysts affecting the salivary and minor mucous glands of the head and neck are common and may be developmental or reactive in nature. Retention and extravasation cysts (mucoceles) are the most common and may arise at any site associated with minor glands that are found throughout the submucosa of the upper aerodigestive tract and paranasal sinuses. Here we include cystic lesions of the major salivary glands as well as cysts associated with minor glands of the oral cavity and maxillary sinus. Ranula is included as a separate lesion because it has distinctive and specific clinical features and problems of management. Cystic neoplasms are not included. Intraoral lymphoepithelial cysts are included in this category even though their origin is uncertain. Some arise from intraoral tonsillar tissue, while others appear to be associated with dilated ducts of minor salivary gland.
