Essential thrombocythemia （ET） is a myeloproliferative neoplasm characterized by an increase in platelets owing to abnormalities in bone marrow hematopoietic stem cells. There is a risk of thrombosis and bleeding in perioperative management. We report a case of performing surgery for condylar fracture accompanied by ET. A female in her 40s was injured by being struck on her right cheek. The clinical diagnosis from imaging examinations was right condylar base fracture. Open reduction and internal fixation was the treatment plan. She had been treated with hydroxycarbamide and aspirin since a diagnosis of ET in the past. The platelet count was stable at 100×104/μL or less. She discontinued aspirin one week before surgery and underwent ORIF using a high perimandibular approach. She recovered well after surgery and had no perioperative complications.
