Chrysomyabezziana associated Oral Myiasis - a case report

Myiasis is an infestation of vertebrates with dipteran larvae. In humans myiasis of cutaneous wound is common and that of the oral cavity is less common. Oral myiasis occurs due to deposition of eggs by the female fly belonging to Chrysomyabezziana. The condition is common in patients unable to maintain proper oral hygiene such as mentally challenged individuals, epileptic patients, patients with cerebrovascular accidents and those with non-healing oral ulcers. Predisposing factors include mouth breathing, incompetent lip seal, alcoholism, halitosis, poor oral hygiene, disability, senility, facial trauma, periodontal diseases and oral extraction wounds. Presence of oral myiasis in patients who are medically stable and able to maintain good oral hygiene is rare. Due to increasing incidence of alcoholism, myiasis can also occur in those who cannot maintain a lip seal. Here we present a case of oral myiasis in a medically stable male individual with chronic alcoholism and discuss the entomological aspect, identification and management.Key Words: Screw Worm Infection; oviposition; larva; diptera
