Summary
Frozen section (FS) is highly accurate for diagnosing parotid tumors during surgery, improving patient outcomes. Fine-needle aspiration (FNA) is less accurate but still valuable for preoperative assessment of parotid lesions.
Area of Science:
- Head and Neck Surgery
- Surgical Pathology
- Oncology
Background:
- Preoperative diagnosis of salivary gland lesions, particularly parotid tumors, remains a challenge.
- Fine-needle aspiration (FNA) has limitations in accuracy for parotid lesions.
- Frozen section (FS) is increasingly recognized for its intraoperative diagnostic utility.
Observation:
- A retrospective review of 85 parotid lesions treated between 1998 and 2003 was conducted.
- Data from FNA, FS, and definitive pathology were collected and compared.
- Surgical decisions were altered in six cases based on FS findings.
Findings:
- Frozen section (FS) demonstrated 100% accuracy in differentiating benign from malignant parotid tumors.
- FS correctly classified 30 cases, significantly aiding surgical management.
- Fine-needle aspiration (FNA) showed a sensitivity of 77.2% and specificity of 90% for parotid lesions.
Implications:
- Routine use of frozen section (FS) in parotid surgery is recommended for accurate intraoperative diagnosis.
- FS can alter surgical management, potentially improving patient outcomes.
- FS offers an accurate, cost-effective method for parotid tumor diagnosis during surgery.
