Oral myiasis in an adult associated with filariasis and Hansen′s disease

Abstract

Oral myiasis is a common parasitic infestation of live human and animals caused by species of dipteran fly larvae known as maggots which may be secondary to medical disease. This case involves a 51-year-old female, poorly debilitated with advanced periodontal disease infected by the dipteral larvae in the anterior maxillary region which belonged to the family Calliphoridae and Chrysomya bezziana species. This lady was neglected from her family and presented oral myiasis with the previous history of filariasis and Hansen's disease. Secondary infestations may occur in cancrum oris, oral extraction wounds, jaw bone wounds, oral leprosy lesion, filariasis, and carcinoma. Hansen's disease (leprosy) is bacterial in origin whereas filariasis (elephantiasis) is parasitic in origin like-myiasis. The treatment consisted of manual removal of the larvae by topical application of turpentine oil, oral therapy, and surgical debridement of the oral wound.

Head and neck myiasis: a case series and review of the literature

“…This antiparasitic agent of the macrolide family blocks nerve impulses at the nerve endings of endoparasites, causing paralysis and death of the larvae. 13 The sequelae of myiasis include blindness, hearing loss, and even death, and immediate treatment is thus essential. 14 This report describes 9 cases of myiasis affecting the head and neck region and discusses the demographic distribution, treatment, clinical characteristics, and sequelae of the disease in light of the literature.…”

Oral myiasis: Analysis of cases reported in the English literature from 1990 to 2020

A Rare Occurrence of Oral Myiasis in the Posterior Region of the Jaw

“…12 A PubMed literature search reveals that oral myiasis caused due to CB is an uncommon finding, even more rare is its occurrence in the posterior region. 8,[11][12][13][14] Oral myiasis caused by CB in the posterior region is rare. 15 However, this case report is the first case wherein the mandibular molar region had been affected.…”
