Study Notes

Salivary Gland Disorders

Salivary stones, also known as sialoliths, can develop in any salivary gland, but are more common in the upper lip area and the submandibular gland due to its anatomy.
Salivary stones start as a nidus, accumulate layers of mineralization from saliva, and can cause discomfort, especially around meal times.
Factors such as post-surgery, medications reducing salivary flow, dehydration, and obstructive phenomena can contribute to the development of salivary stones.
Obstructive sialadenitis, inflammation of salivary gland tissue, can be caused by infectious (viral, bacterial) and non-infectious factors (sarcoidosis, Sjögren syndrome, radiation therapy).
Sarcoidosis and Sjögren syndrome are non-infectious inflammatory conditions that can affect salivary gland tissue.
Infections such as viral (e.g., mumps, CMV) and bacterial can lead to obstructive sialadenitis, often associated with post-surgical complications or decreased salivary flow.
Salivary stones can be visualized as a palpably firm mass in an excretory duct and can be seen on imaging, such as occlusal radiographs.
Salivary stones can grow quite large, causing discomfort, and are composed of layers of mineralized material.
Salivary gland disorders can lead to obstructive phenomena, decreased salivary flow, and complications like sialadenitis.
Salivary gland disorders can be caused by traumatic events, infections, decreased salivary flow, and non-infectious inflammatory conditions.
Radiation therapy can also lead to salivary gland disorders, though it is not very common.
Salivary gland disorders can lead to discomfort, and in some cases, imaging may be used to visualize the condition and guide treatment.
