Surgical and microscopic anatomy of parotid and submandibular salivary glands of rhesus monkeys (Macaca mulatta).

Wedge biopsy of the caudal borders of the parotid or submandibular salivary glands of rhesus monkeys avoids major nerves, ducts, and blood vessels. This is a minor surgical procedure that provides adequate material for in vitro studies and causes no significant postoperative complications. Gross and light microscopic anatomy of the rhesus and human salivary glands are similar. We have concluded that rhesus monkeys are good models for human salivary diseases, including radiation sialoadenitis.
