[The clinical value of recurrent laryngeal nerve dissection in the surgical treatment for congenital pyriform sinus fistula].

Objective

To explore the clinical value of recurrent laryngeal nerve dissection in the surgical treatment for congenital pyriform sinus fistula（CPSF）.

Methods

The clinical data of 42 patients with CPSF were retrospectively analyzed. All patients were diagnosed and treated in the First Affiliated Hospital of Guangdong Pharmaceutical University.

Results

During the operation, all patients' recurrent laryngeal nerves were dissected successfully, and fistulas were resected completely,no patients had complication of recurrent laryngeal nerve's damage.There were no recurrence cases during the 13 to 48 months of follow-up.

Conclusion

The trend of congenital pyriform sinus fistula is closely related to recurrent laryngeal nerve, it's important to dissect the recurrent laryngeal nerve during the operation for congenital pyriform sinus fistula.
