The choice between different types of glossectomy mainly depends on the tumour’s size, location and how deeply it has grown into the tongue. Your surgeon also considers whether nearby tissues are affected and how much healthy tissue must be removed around the tumour to achieve clear margins. The glossectomy classification describes how much tongue is removed. A partial glossectomy removes a portion, a hemiglossectomy removes half, a subtotal glossectomy removes most, and a total glossectomy removes the whole tongue. Smaller, localised tumours may need less extensive surgery, while larger tumours may require more tissue removal and reconstruction. Your overall health, previous treatment and expected effects on speech and swallowing also influence the treatment plan. The aim is to remove the disease while preserving as much tongue function as safely possible. The operation cannot be decided from symptoms or tumour size alone. Conclusion: Your head and neck cancer team recommends the operation after reviewing your examination, biopsy and scans. Ask your surgeon how much tongue needs removal, why, and what reconstruction and recovery support you may need.
