Summary
Partial parotidectomy offers excellent tumor control for pleomorphic adenoma with minimal facial nerve issues. This study confirms its safety and effectiveness in managing parotid gland tumors in an academic setting.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Surgical Oncology
Background:
- Pleomorphic adenoma is the most common benign salivary gland tumor.
- Parotid gland tumors require careful surgical management to preserve facial nerve function.
- Partial parotidectomy is a key surgical approach for these tumors.
Purpose of the Study:
- To evaluate long-term tumor control and functional outcomes of partial parotidectomy.
- To assess facial nerve outcomes following parotidectomy for pleomorphic adenoma.
- To analyze recurrence rates in a large single-surgeon cohort.
Main Methods:
- Retrospective review of 363 patients undergoing parotidectomy for pleomorphic adenoma.
- Analysis of demographic data, tumor characteristics, and operative details.
- Long-term follow-up (average 10 years) for tumor recurrence and facial nerve function.
Main Results:
- Low rates of facial nerve weakness: 5.2% short-term, 1.4% long-term.
- Tumor recurrence was rare (0.6%).
- Deep-seated tumors showed higher short-term facial nerve paresis risk, but long-term outcomes were similar.
Conclusions:
- Partial parotidectomy provides excellent tumor control for pleomorphic adenoma.
- The procedure demonstrates a favorable safety profile with low facial nerve dysfunction.
- It is a safe and effective management strategy in an academic training environment.
