Aural myiasis can be defined as fly larvae feeding on the host’s ear. It is a rare condition and occurs mostly in
children and the mentally retarded adults. We present a 40-year-old, mentally healthy, farmer with aural myiasis.
Clinical examination revealed live maggots filling the left external ear canal (EAC). Twenty-three live maggots
were remov...

p>Aural myiasis refers to the infestation of the ear by the larvae of certain dipterous flies. The disease-producing flies prefer a warm and humid environment and higher incidence occur in tropics and subtropics of Africa and America. Aural myiasis is rare during neonatal life and children with tendencies of poking the ear need immediate review by otorhinolaryngologists for thorough otological review. The objective is thus to report the case of a 24-day old neonate who was diagnosed to have aural myiasis upon otoendoscopy at a private health facility in Tanzania. This is the first reported case of neonatal aural myiasis in our country. Neonates with tendencies to poke ears and with irritability should be handled with care by having immediate Otorhinolaryngologist review to exclude aural pathologies such as aural myiasis. Removal of the maggot, instilling ototopical antibiotics admixed with aural antiseptics, systemic antibiotics and close follow up for meticulous aural toilet remains the main stay in management of aural myiasis.</p
There are a limited number of parasites that involve the human ear, with most being arthropods, such as ticks, mites, and fly larvae. The helminth Lagochilascaris minor can also rarely infect the middle ear and surrounding anatomic structures. This chapter provides an overview of these parasites, with an emphasis on their biology, associated clinical manifestations. Diagnosis and treatment of infection/infestation will also be covered.
A checklist of 153 flesh fly species (Diptera, Sarcophagidae) recorded to date from Turkey is presented. Updating the list was necessary due to the numerous recent records. Records are listed according to provinces.
Objective
Myiasis is the infestation of live humans (or animals) by fly larvae. Although the diagnosis is relatively straightforward, how to best treat aural myiasis has not been well described in the literature. This comprehensive literature review, therefore, was performed to identify current management principles in aural myiasis, especially with regard to the causative fly family. In addition, we explore the possible relationship between aural myiasis and the highly lethal intracranial myiasis.
Data Sources
Literature review using the Medline database (PubMed), Scopus, and Google Scholar.
Review Methods
Manuscripts published in the English language between January 1, 1992, and December 31, 2012, were included.
Results
Forty-five cases of aural myiasis were reported in 34 manuscripts. Most cases were caused by species of the Sarcophagidae family (n = 26/45, 57.8%). The majority of cases (n = 40/45, 88.9%) were successfully treated with simple aural toilet and topical treatments alone. No deaths were reported and no cases were seen in conjunction with intracranial myiasis.
Conclusion
Aural myiasis is a rare but benign fly infestation of the ear, most commonly by species of the Sarcophagidae family. The overwhelming majority of cases can be successfully managed without the need for surgical intervention.
Myiasis has been defined as the infestation of tissue with dipterous larvae that feed on the host's dead or living tissue. A new clinical report of otomyiasis in a 57-year-old woman caused by Wohlfahrtia magnifica was reported. A review of the English language literature reveals 5 articles on otomyiasis cases caused by W. magnifica. Although it is not a frequent manifestation in otorhinolaryngology, the opportunity of its occurrence always exists. In the treatment, a combination of suctioning and alligator forceps was used to remove larvae. Also, tympanoplasty was performed for the reconstruction of perforated ear.
