Salivary gland surgery

Humans have six major salivary glands (two each in the ear, lower jaw and under the tongue) as well as a large number of minor salivary glands in the mucous membranes of the cheeks, palate and lips. Together, they produce around 1.5 litres of saliva daily.

Disorders of the salivary glands can be caused by bacteria and viruses (e.g. mumps), but also by changes in the tissue (salivary stones, tumours). The latter can block the gland’s duct, preventing saliva from draining away. Pain associated with increased salivation (e.g. when eating) and a swollen gland indicate such a blockage.

In 75 per cent of cases, salivary gland tumours are benign growths. They grow slowly, rarely cause symptoms and occur predominantly in the parotid gland. Malignant tumours occur more frequently in the minor salivary glands and the submandibular glands.

Following a thorough diagnostic assessment – including ultrasound, CT or MRI scans – only surgical intervention can help in these cases.

The operations require a hospital stay of 3 to 5 days, depending on the procedure, and the recovery period is approximately 2 weeks.
