Oral Myiasis Caused by Musca domestica Larvae

Myiasis refers to the infestation of human and animal tissues by fly larvae. Oral myiasis is a relatively rare condition typically affecting individuals with low socio-economic status and poor hygiene. This case report describes a 21-year-old male patient with a history of chronic smoking and ischemic stroke, who developed oral myiasis following intubation for glioblastoma surgery. After 10 days post-operation, multiple larvae were identified in the oral cavity. Manual extraction and treatment with metronidazole were performed, leading to initial healing. However, the patient subsequently developed respiratory infection and septic shock, ultimately resulting in death. The report highlights the importance of prevention over treatment, emphasizing individual hygiene and collective measures to control house fly populations and improve living conditions. Effective management of myiasis requires awareness of predisposing factors and timely intervention to avoid serious complications.
