Unanticipated restricted mouth opening after induction of general anesthesia in a patient with parotid gland swelling

We report a case of unanticipated difficult airway management due to restricted mouth opening in a patient with parotid gland swelling. A 47-year-old female (156  cm, 47 kg) who had underwent chemotherapy for MALT lymphoma from 6 years ago developed right parotid gland swelling, which was detected by computed tomography (Fig. 1). Elective open biopsy was scheduled under general anesthesia. She had no pain or difficulty opening her mouth. Mallampati cla ss was 1 and preoperative airway examination showed no airway management risk.
