Abstract:
Manned spaceflight places special demands on the human body, including the organs in the ENT region. These organs play a critical role in maintaining the health and safety of astronauts in space. In this paper, we review common ENT problems of spaceflight, including upper airway edema, middle ear and mastoid effusions, hearing loss, and dizziness with nausea. We discuss the underlying mechanisms contributing to these complaints, their clinical manifestations, and potential treatment strategies. In addition, we examine the potential impact of these conditions on astronaut health and mission outcomes. Finally, we emphasize the importance of preventive measures and future research in this area to optimize astronaut health and safety on future missions.
