Surgical Approach |
Indications/Criteria |
Postoperative Management |
| American Head and Neck Society (AHNS) [4] |
Extracapsular dissection (ECD) is recommended for small, benign, and mobile parotid tumours. |
ECD |
Tumours <4 cm, no facial nerve involvement |
Routine follow-up with MRI/CT every 6-12 months |
| European Society for Medical Oncology (ESMO) [8] |
Advocates ECD for low-grade benign tumours, while traditional surgery is recommended for larger or malignant tumours. |
ECD, Superficial Parotidectomy |
Small, benign tumours, high-risk tumours (traditional surgery) |
Regular clinical examination and imaging |
| National Comprehensive Cancer Network (NCCN) [38] |
Recommends traditional surgery for malignant parotid tumours, particularly those involving facial nerve preservation. |
Superficial or Total Parotidectomy |
Malignant tumours, tumours >4 cm, facial nerve involvement |
Radiotherapy in high-risk cases, follow-up imaging |
| British Association of Head and Neck Oncologists (BAHNO) [8] |
Suggests ECD for benign lesions without facial nerve complications and traditional surgery for malignancies. |
ECD, Traditional Parotidectomy |
Benign tumors (ECD), Malignant tumors (Traditional Surgery) |
Monitoring with imaging, potential adjuvant therapy |
| American Society of Clinical Oncology (ASCO) [8] |
Advises traditional surgery for high-risk patients and larger tumours, while ECD is acceptable for benign, smaller tumours. |
ECD, Total or Superficial Parotidectomy |
Benign tumours <4 cm, malignant or recurrent tumours |
Surveillance and optional adjuvant radiotherapy for malignancies |
