Surgery was performed by the senior authors using the same technique at the same clinical center for all patients. The median follow\u2010up time was 33\u2009months. Meantime, we collected information on patients with pyriform fistula using traditional surgical methods in our hospital from April 2015 to November 2018 for comparison.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The surgery was successfully completed in 36 patients. In all, 32 patients had a history of multiple incisions and drainage, 16 patients had a history of surgical resections, and two patients had a history of cauterization of the internal fistula. Compared with traditional surgical methods, our new surgical method greatly shortens the length of the surgical incision (4.3 vs. 5.5, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001), reduces the operation time (8.1 vs. 27.1, <jats:italic>p<\/jats:italic> &lt;\u20090.0001), and reduces the blood loss (103.2 vs. 196.8, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001). None of the 36 patients in this study had complications such as pharyngeal fistula, recurrent laryngeal nerve paralysis, or hypothyroidism. The mean follow\u2010up duration after the excision of the lesion was 34.1\u00a0months. To date, no patients have relapsed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our experience showed that this surgical technique could be used to completely remove the fistula, and it was easier to perform than the conventional strategies.
