Summary
This study reviewed 125 patients with benign parotid neoplasms, finding superficial parotidectomy to be the minimum effective surgical treatment. The analysis highlights surgical outcomes and morbidity for these common parotid gland tumors.
Area of Science:
- Otolaryngology
- Surgical Oncology
- Head and Neck Surgery
Background:
- Benign parotid neoplasms are common salivary gland tumors.
- Surgical management aims for complete tumor removal while preserving facial nerve function.
- Various surgical techniques exist for parotid gland tumor excision.
Purpose of the Study:
- To evaluate the surgical treatment outcomes for benign parotid neoplasms.
- To assess the morbidity and recurrence rates associated with different surgical procedures.
- To determine the optimal surgical approach for benign parotid tumors.
Main Methods:
- Retrospective review of 125 patients with benign parotid neoplasms treated surgically over 24 years.
- Analysis of 128 excised tumors, including pleomorphic adenomas and Warthin's tumors.
- Categorization of surgical procedures: local excision, enucleation, superficial/subtotal/radical parotidectomy.
Main Results:
- Superficial parotidectomy was the most common procedure (88 cases).
- Overall morbidity was 49%, with facial nerve paralysis (permanent and transient) occurring in a significant percentage of patients.
- Low recurrence rate (0.7%) observed after a median follow-up of 84 months.
Conclusions:
- Superficial parotidectomy is recommended as the minimum surgical procedure for benign parotid neoplasms.
- Careful surgical technique is crucial to minimize facial nerve injury and other complications.
- Long-term follow-up is important for assessing recurrence in benign parotid tumors.
