Conclusion
In summary, the paraglottic space approach is a novel surgical approach, which can better expose the tumour. On the premise of ensuring a safe tumour resection margin, this approach has obvious advantages in preserving laryngeal function and reducing the serious postoperative complications of pyriform sinus carcinoma. It is beneficial in improving the quality of life of patients after surgery. This surgical approach can be applied in patients with lesions that do not involve the paraglottic space. N stage is an independent risk factor for postoperative survival. This study still has the deficiency of a relatively small sample size. Nonetheless, the resection method for primary postcricoid carcinoma and posterior pharyngeal wall carcinoma via the paraglottic space approach is worth further exploring and trying.
