Laryngeal granuloma development can be a postoperative complication of laryngeal trauma or irritation resulting from general anesthesia and endotracheal intubation. These rare benign lesions are located primarily over the cartilaginous portions of the larynx, particularly the vocal processes of the arytenoids. Airway manipulation during the intubation process and prolonged intubation periods can be contributing factors to intubation-related laryngeal granulomas, which may manifest 1 to 4 months after intubation. The patient in this case was a female who returned with complaints of throat pain without hoarseness or sensations of a “lump in her throat” 3 months following surgery, during which she was intubated with a 7.0-mm nasotracheal tube for 30 hours, likely contributing to her bilateral laryngeal granulomas. The patient underwent successful conservative medical management consisting of a proton pump inhibitor and an inhaled corticosteroid.
