Abstract: | Pyriform sinus fistula causes acute suppurative thyroiditis, and there is a risk of recurrence if the sinus tract is not excised
completely. The tract should be dissected as high as possible toward the pyriform fossa. We report our devised technique “the
light guided procedure” for the impalpable fistula. A bronchoscope was inserted into the pyriform sinus fistula with the help
of a gastrofiberscope positioned at the larynx. The tract of the fistula was identified with the help of the light from the
bronchoscope. We were able to reach the proximal end of the fistula, directly. This procedure is easy, safe, and minimally
invasive. |
