Myiasis is a rare but risky pathology caused by a parasitic infestation of humans and animals by the dipterous larva. Oral myiasis occurs when soft tissues of the oral cavity are invaded by the larvae of flies. It is not a common disease for the reason that the oral cavity is not easily reachable for the fly to lay eggs. But it can cause pain, infection, uncomfortable feeling when the worms move, tissue destruction and/or even life-threatening hemorrhages.
We reported a case of oral myiasis after cerebral infarction in a 78-year-old male patient from southern China (Guangdong Zhanjiang). As a result of cerebral infarction, he suffered from right hemiplegia, mobility and mental decline for about 3 mo. He had difficulty swallowing and was fed via a feeding tube. He mostly engaged in mouth breathing and had poor oral and dental hygiene. More than 20 live larvae were collected from the patient’s oral cavity, which were localized in the maxillary gingiva, the mandibular gingiva and the tongue. The patient recovered after the routine oral cleaning, removal of maggots, debridement and anti-infection treatment.
Early diagnosis and treatment of this infestation are essential due to the bothersome symptoms, such as inflammation, intense anxiety over the larvae movement, possible serious complications, etc. Clinical staff should be familiar with this infestation, and this disease should be considered, especially in physically and mentally disabled patients or those at significant risk for infection. Necessary measures, including good sanitation, personal and environmental hygiene and special care should be adopted so as to prevent this disease.
