Transoral robotic surgery base of tongue mucosectomy for head and neck cancer of unknown primary

Head and neck cancer of unknown primary (HNCUP) is a source of diagnostic uncertainty. Patients presenting with cytologically positive neck lumps without a clinically identifiable primary, require extensive investigation including imaging, tonsillectomy, panendoscopy and tissue biopsy. Treatment typically involves neck dissection, wide field radiotherapy and chemotherapy. Transoral robotic surgery (TORS) has emerged as an expanding surgical technique for resecting tumours of the oropharynx. Its role in base of tongue (BOT) mucosectomy for HNCUP can alleviate diagnostic uncertainty and provide an adjunct treatment modality with few complications.
