ABSTRACT
Nasal myiasis is a rare parasitic disease. The growth of myiasis in the nasal cavity causes damage to the nasal cavity and paranasal sinuses. Once the dipeterous larvae are migrated, it causes damage to the surrounding structures such as eyes and skull cavity. Proper treatment and active prevention and control can reduce and avoid the occurrence of serious complications. On May 14, 2020, a patient with cerebral infarction and coma was admitted to Xiangya Hospital of Central South University and developed nasal myiasis. During the treatment of the primary disease, the patient was found to be infected with rhinomyiasis. The patient was treated with dehydration, cranial pressure reduction, brain protection, blood glucose control, blood pressure control, and anti-infection. Nasal endoscopy and nasal irrigation were carried out to treat nasal myiasis. The patient was properly placed and isolated for prevention and control so as to prevent the spread of myiasis in the ward. After 16 days, the patient regained consciousness, no worm was found in the nasal cavity, and was discharged from the hospital. The patient was followed-up for 6 months, no maggots were found in the nasal cavity of the patients, no complaints of nasal discomfort was occurred, and no other patients and medical staff were infected with myiasis. The prevention of myiasis is very important, and proper measures should be taken to reduce the risk of community and hospital infection.
