Parotid gland

Parotid gland
Parotid salivary gland is situated at the root of the ear lobe. The facial nerve which supplies the muscles of facial expression is under the gland. Among all the salivary glands, Parotid has the highest incidence of tumours. To diagnose parotid swellings, ultra sound scanning and fine needle aspiration biopsy helps. Sometimes CT and MRI scans are done to decide the depth of tumour and the spread to the surrounding tissue. All parotid tumours should be operated to know the exact nature of it. Since the facial nerve is underneath the gland, a special type of incision which goes round the ear is used to protect all the branches of the nerve. The facial nerve is carefully dissected before we remove the gland with the tumour. When the wound is healed, scar is also invisible.
