Parotid Gland Stones

In the older patient salivary stones occur with a higher frequency. In patients who have a tendency for gout, the frequency of parotid gland stones is even higher. Essentially these stones come from calcium or uric acid salts that precipitate in the ducts of the parotid and submandibular glands. Parotid gland stones occur in about 20%, submandibular gland stones in 80% of all salivary gland stones.

Symptoms:

There is a painful swelling of the affected gland particularly with eating as more digestive juices are produced, but get congested behind the stone that plugs the parotid gland duct. The pain can get so severe that the term "salivary colic" was coined to describe it medically (Ref. 8).

Because there is congestion and a lot of digestive enzymes in the ducts, bacteria find their way into the duct and tissue, and painful local abscesses and local bacterial parotitis develop. Even when this is successfully treated with antibiotics, a vicious cycle of scarring, congestion, further stone formation and more infections may develop.

Diagnostic Tests:

According to Ref. 8, p. 822, intraoral radiographs and occlusal X-ray views detect up to 94% of all stones. CT scanning and sialograms (where the ducts are filled with a contrast material followed by X-rays) complete the work-up. With those patients who are allergic to contrast material ultrasound examination can detect up to 90% of the stones that are larger than 2mm in diameter (Ref.8).

Treatment:

The newest treatment for parotid gland stones is extracorporal lithotripsy (=ECL) treatment. This technique has been successfully employed to break kidney stones down to the size of sand like particles, which can be passed naturally. With parotid gland stones the same technique has been successfully adapted and this should likely be attempted first before the conventional surgical approach would be employed. According to Ref. 8 more than 50% of parotid gland stones can be treated successfully with ECL. Submandibular gland stones have to be treated with conventional surgery as ECL is not that successful there.

Pain Control:

There is an FDA approved non-drug method available, IceWave patches from Lifewave, which will control pain. This is mentioned in the book "Breakthrough" by Suzanne Somers (Ref. 12) where newer insights of antiaging medicine are also reviewed. Although the patches are placed over acupuncture points, there are no needles involved. Nanotechnology, a newer technology, was used in the manufacturing of these patches and infrared (heat) waves from body heat are utilized to stimulate an acupuncture point, which modifies pain perception and reduces pain to half or less. Medically this would be considered an excellent pain reliever. For more info on the patches see the IceWave patches from Lifewave link above (click "products"). In the US a 5 pack of the IceWave spray is available that can be directly sprayed onto the skin in the area where the pain is located.
