Summary
Brief summary (as posted)
To evaluate the efficacy and safety of induction chemotherapy combined with tislelizumab as neoadjuvant therapy in patients with locally advanced squamous cell carcinoma of the external auditory canal; to explore the improvement in the preservation rate of important neurovascular structures (including the facial nerve, internal carotid artery canal, sigmoid sinus, and posterior cranial nerves, etc.).
