Myiasis is a disease caused by fly larvae from the Diptera order settling in various tissues and organs of humans or animals. To report the diagnosis of myiasis larvae invading the oral and nasal cavities of patients in the management of intensive care units and to draw attention to the poor hygiene situation.

On the 21st day of the cancer patient's hospitalization, eight larvae were removed from the oral cavity. In the first month of the other patient's hospitalization, six larvae were seen in the patient's nasal osteum near the feeding tube. A clinical diagnosis of myiasis was made and the larvae were initially manually removed for treatment, followed by medication.
