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.
