A laryngeal polyp is a common benign lesion of phonotraumatic origins. However, a case of the laryngeal polyp with the upper airway obstruction is rare. The common symptoms include hoarseness or reduced vocal quality, and dyspnea could be present in severe cases. Depending on the anatomical location of the polyp, manipulation on the larynx could cause laryngospasm and life-threatening airway obstruction. In this case, the patient underwent a planned cesarean section under general anesthesia. However, her breathing rhythm did not return spontaneously after surgery and she was sent to the intensive care unit. Bilateral laryngeal polyps were discovered after the removal of an endotracheal tube. However, there was a delay in the removal of the polyps, where it was performed two months after the intensive care unit discharge. The histopathological results confirmed a diagnosis of bilateral angiomatous laryngeal polyps.
