ANSWER AND REASONINGE. The likelihood of malignancy and need for multidisciplinary staging outweigh any presumption that facial-nerve preservation is automatic
Facial weakness and rapid growth are red flags for malignant parotid disease. Management depends on histology, resectability, nerve involvement and adjuvant-treatment planning; a promise to preserve a clinically invaded nerve would be inappropriate.
Why every option is right or wrong
A. Treat as Warthin tumour because of the patient’s age: Clinical red flags and biopsy findings require oncological assessment.
B. Proceed with superficial parotidectomy without staging: Deep-lobe disease and possible malignancy require a planned oncological operation.
C. Offer facial-nerve sacrifice before discussing alternatives: The decision requires histological, functional and patient-centred discussion.
D. Manage with sialogogues and review in six months: This would dangerously delay a likely malignancy.
E. The likelihood of malignancy and need for multidisciplinary staging outweigh any presumption that facial-nerve preservation is automatic: Facial weakness and rapid growth are red flags for malignant parotid disease. Management depends on histology, resectability, nerve involvement and adjuvant-treatment planning; a promise to preserve a clinically invaded nerve would be inappropriate.
What if the scenario changed?
If a well-defined superficial mass had benign cytology and normal facial function, a conservative parotid surgical discussion would be more appropriate.
