A 56-year-old male was diagnosed as right lower pharynx carcinoma by upper gastrointestinal endoscopy gastrointestinal endoscopy, and underwent endoscopic laryngo-pharyngeal surgery to resect the lesion. The iodine-unstained area was suspected of being cancerous and was also resected. The resected area may adhere to surrounding tissues, which may affect the patient's swallowing function in the future. Local injection of triamcinolone acetonide to the desquamated site to prevent adhesions did not result in stenosis during postoperative follow-up.
