A pleomorphic adenoma of the parotid gland is best managed by which surgical approach to minimize recurrence?
- A Superficial parotidectomy with a cuff of normal parotid tissue ✓
- B Enucleation of the tumor along its pseudocapsule
- C Total parotidectomy with deliberate sacrifice of facial nerve
- D Incision and drainage followed by radiotherapy
Correct answer: A. Superficial parotidectomy with a cuff of normal parotid tissue
Explanation
Pleomorphic adenoma has an irregular pseudocapsule with microscopic projections (satellite nodules) that extend beyond the apparent tumor margin. Enucleation alone risks violating these extensions and results in recurrence rates of up to 20–45%. Superficial parotidectomy with a 1 cm cuff of normal parotid tissue around the tumor, performed with facial nerve identification and preservation, reduces recurrence to <4%. Total parotidectomy with nerve sacrifice is reserved for malignant tumors.
