Salivary Gland Diseases

Stones in Salivary Glands

Submandibular Stone

Submandibular Stone

• Salivary gland diseases are common in ENT practice.
• Stones in the sub-mandibular gland leading to swelling and inflammation are the most common cause of submandibular gland swellings.
• Stones in the sub-mandibular gland are best removed by surgical removal of the submandibular gland.
• If stones are seen in the floor of mouth, these can be removed intra-orally.
• Stones are rarer in the parotid gland and usually seen in Stensons duct. Endoscopic removal can be performed.

Parotid Gland Tumor

Parotid Tumor

• Parotid gland tumors usually present as a lump below the ear lobe or at the angle of jaw.
• They are mostly benign (90%).
• The most common tumor is that of a pleomorphic adenoma.
• A local excision of this parotid mass is not advised because of danger to the facial nerve and extension of tumor outside of the pseudo-capsule. Hence, surgical removal would require a rim of normal parotid tissue outside the tumor capsule as in a superficial parotidectomy with facial nerve preservation is the operation of choice.
• The minimum operation is a superficial parotidectomy with facial nerve preservation.

Recurrent Pleomorphic Adenoma of the Parotid Gland

Recurrent Pleomorphic Adenoma of the Parotid Gland with skin involvement

Facial Nerve Preservation after Total Parotidectomy

• This patient has a recurrent pleomorphine adenoma because of inadequate primary surgery.
• A total parotidectomy with facial nerve preservation including uninvolved skin around the previous scar in the minimum operation.
