The major salivary glands are the parotid (in front of the ear) and submandibular (under the jaw). Stones can block saliva flow and cause painful swelling during meals. Lumps within the glands are usually benign tumours but should be evaluated and often removed.

How it is diagnosed
Clinical examination
Ultrasound
FNAC (needle test)
CT or MRI when needed
Treatment
Infections are treated with medicines, hydration and massage. Stones may be removed through the mouth if accessible. Recurrent problems or tumours are treated by submandibular gland excision or parotidectomy, with careful nerve preservation.
Surgical treatment options
See a doctor promptly if you have:
- A lump that keeps growing
- Facial weakness with a swelling
- Swelling with fever and pus
