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.
