Pyriform sinus fistula is a rare branchial pouch anomaly, which causes recurrent neck abscess. Although complete excision of the fistula tract is considered as a definitive treatment for pyriform sinus fistula, it has been suggested that chemocauterization with trichloroacetic acid (TCA) of the internal opening is a reasonable treatment. For this purpose identifying the existence of an internal opening is important. Here, we describe the Modified Killian’s method, a recently proposed simple endoscopic technique to observe a wider area of the hypopharyngeal space, and show that it is helpful to identify the internal opening of the pyriform sinus fistula. The Modified Killian’s method is a suitable examination for pyriform sinus fistula prior to TCA chemocauterization.
