A safe and effective surgical method for complex pyriform sinus fistula.

Area of Science:

• Otolaryngology
• Surgical Innovation

Background:

• Pyriform fistula is a congenital anomaly that can lead to recurrent infections and complications.
• Traditional surgical methods for pyriform fistula often involve extensive dissection and have a high recurrence rate.

Purpose of the Study:

• To introduce and evaluate a novel surgical technique for the treatment of pyriform fistula, particularly complex cases.
• To compare the efficacy and safety of the new technique against conventional surgical methods.

Main Methods:

• A cohort of 36 patients with pyriform fistula underwent the new surgical procedure between August 2017 and October 2020.
• Data from patients treated with traditional methods (April 2015 to November 2018) were collected for comparative analysis.
• Key outcomes measured included surgical incision length, operation time, blood loss, and complication rates.

Main Results:

• The new surgical method resulted in significantly shorter incision lengths (4.3 vs. 5.5 cm, p < 0.0001), reduced operation times (8.1 vs. 27.1 min, p < 0.0001), and less blood loss (103.2 vs. 196.8 mL, p < 0.0001) compared to traditional methods.
• No complications such as pharyngeal fistula, recurrent laryngeal nerve paralysis, or hypothyroidism were observed in the 36 patients.
• The mean follow-up duration was 33 months, with no reported relapses.

Conclusions:

• The novel surgical technique provides a less traumatic and more effective treatment for pyriform fistulas.
• This method is particularly advantageous for managing complex pyriform fistulas, offering reliable outcomes.
