Summary
Recurrent benign parotid tumors are uncommon after initial surgery. Careful follow-up and pre-operative diagnosis are crucial for managing these slow-growing lesions and potential malignant transformations.
Area of Science:
- Otolaryngology
- Surgical Oncology
- Head and Neck Surgery
Background:
- Benign parotid tumors can recur after surgical excision.
- Understanding recurrence patterns is essential for patient management.
Purpose of the Study:
- To investigate the behavior of recurrent benign parotid tumors.
- To characterize recurrence patterns and surgical challenges.
Main Methods:
- Retrospective chart review of a single surgeon's cases from 1971-1996.
- Analysis of patient demographics, tumor types, recurrence characteristics, and surgical outcomes.
Main Results:
- 24 patients underwent re-operation for recurrent tumors.
- Most common recurrence was pleomorphic adenoma; malignant transformation occurred in one case.
- Facial nerve paralysis affected 53% of patients, with 15% permanent.
Conclusions:
- Recurrence rates are low (0-4%) after initial superficial parotidectomy.
- Lengthy follow-up is necessary due to slow growth; pre-operative diagnosis aids planning.
- Consider malignant transformation and potential nerve injury during re-operation.
