Abstract

Pharyngocutaneous fistula is a readily encountered complication that occurs after surgery forlaryngopharyngeal cancer. The development of pharyngocutaneous fistula increases hospitalization,delays postoperative adjuvant treatment, and can lead to serious complications such aswound infection and carotid artery rupture. Transoral robotic surgery (TORS) is actively beingperformed as a standard procedure for surgery of pharyngeal and laryngeal cancers. Manyreports verified that TORS is advantageous in terms of perioperative outcomes such as decreasedhospitalization and reduced rate of postoperative complications, free flap reconstruction,and tracheostomy or gastrostomy tube dependence relative to open surgery. However,careful selection of patients is mandatory and there are some critical points to consider in optimaltreatment outcomes. Recently, we experienced a 47-year-old patient with tonsillar cancerwho underwent lateral oropharyngectomy by TORS and radical neck dissection. Unfortunately,multiple pharyngocutaneous fistulae occurred following postoperative concurrent chemoradiotherapy(CCRT). Multiple phrayngocutaneous fistulae following TORS and postoperativeCCRT have not been reported in the literature. Therefore, we report this case with a briefdiscussion supported by a review of the relevant literature.
