What is a common treatment for a pleomorphic adenoma located in the deep parotid gland?

A pleomorphic adenoma, also known as a benign mixed tumor, most commonly occurs in the parotid gland. When located in the deep lobe of the parotid gland, the preferred treatment is a superficial parotidectomy. This procedure involves the removal of the superficial lobe of the parotid gland while preserving the facial nerve, which is crucial for maintaining facial function.

The rationale for this approach lies in the need to adequately address the tumor while minimizing the risk of nerve damage. Superficial parotidectomy is typically effective because most pleomorphic adenomas can be found within the superficial lobe, and this surgery allows for complete excision of the tumor, reducing the risk of recurrence. It also balances the need for thorough treatment with the preservation of as much glandular function and facial nerve integrity as possible.

While radical parotidectomy removes the entire gland and is often used for malignant tumors, it is more extensive than necessary for benign conditions like pleomorphic adenomas. Subtotal parotidectomy, which involves removing a portion of the gland but not the entire superficial lobe, may leave residual tumor tissue, increasing the likelihood of recurrence. Transoral excision is not typically used for deep lobe tumors due
