J. Jpn. Bronchoesophagol. Soc., 73 : 210─215, 2022In every medical field, there are many surgeries that involve the use of artificial materials. However, when an infection occurs around an artificial material, which is a foreign substance, con-trol is often difficult. We report a case of arytenoid adduction combined with type 1 thyroplasty that led to Gore-tex deviation caused by infection. The case was a 51-year-old man who underwent right thyroidectomy several years ago. He first visited our department the following year with a complaint of hoarseness after surgery. His right vocal fold was fixed, and he was diagnosed with postoperative right recurrent nerve paralysis. Phonosurgery was performed. During the operation, laryngeal edema was found by endoscopy, a cricoid thyroid ligament incision was performed for safety, and a tube was inserted. Around 7 days after the operation, pus was found discharging from the wound, the tube was removed, and wound irrigation was started. On the 17th day after the operation, the infection was controlled, but the wound was filled with a granuloma and was not closed. The granuloma was removed frequently. At an outpatient visit 3 months after the op-eration, Gore-tex was found deviating from the wound and was removed. One week after removal, the wound closed. This case served to confirm that infected wounds do not close unless the artifi-cial material, a foreign body, is removed. No change of voice was observed even after the removal of the Gore-tex.防のための尿道留置カテーテル感染に関する実態調査．日本感染環境学会誌34：50─54, 2019.13） Isshiki N, Okamura H, Ishikawa T：Thyroplasty type I（lateral compression）for dysphonia due to vocal cord paralysis or atrophy.
