• To determine how a history of head and neck cancer affects recurrence and second tumors after surgery.
• Analysis of patients with hypopharyngeal squamous cell carcinoma after transoral videolaryngoscopic surgery.
• Assessment of early-stage follow-up surveillance outcomes based on prior cancer history.
