Oral myiasis in a cerebral palsy patient: A case report

Abstract

Myiasis is a rare condition caused by the invasion of tissues by the larvae of flies, mainly from the order of Diptera. Many cases of myiasis involving various human organs have been reported. Oral Myiasis is very rare in healthy persons. It occurs mainly in the tropics and is usually associated with inadequate personal and public hygiene; sometimes accompanied by poor manual dexterity. We present a case of oral myiasis in a mentally retarded, 13-year-old boy suffering with cerebral palsy. The diagnosis was based on the characteristic clinical features and the visualization of wriggling larvae. Large numbers of larvae were found in the gingival sulcus. Treatment consisted of manual removal of the larvae, one by one, with the help of turpentine oil and clinical forceps, local debridement of the labial gingival and oral hygiene practice. Healing was uneventful, with resolution of the condition. Key words: Oral myiasis, cerebral palsy, parasitology.Jain S, Gupta S, Jindal SK, Singla A.

Orofacial Myiasis of the Gingiva and Nasal Cavity: A Report of Two Cases and General Review

“…These include patients with poor oral hygiene 21 and severe halitosis, 22 epileptic patients with lacerated lips, 13 advanced periodontal disease, 21,23 fungating cancers, 24,25 and those who keep their mouths open for long periods as in habitual mouth breathers 26 . The condition is seen most often in mentally retarded, 27 psychiatric, 17 comatose, 28 and physically handicapped patients 23,29,30 . These types of patients are not able to ward off flies with their limited locomotor coordination and inability to scratch, and flies sit undisturbed on wound surfaces and lay their eggs, which later turn into larvae.…”

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

“…Efforts were made to contact the authors of three studies; however, their articles could not be retrieved 17–19 . A total of 122 articles reporting 157 cases of oral myiasis were selected 2,5–14,16,20–129 …”

Oral Myiasis: A Rare Case Report

“…When the wound is secondarily infected, broad spectrum antibiotics can be prescribed (Reddy et al, 2012). Recently, a systemic treatment with Ivermectin, derived from avermectin, obtained from actinomycetes, has been found to be effective when given orally in a single dose of 150 to 200 mg/kg of body weight and repeated, if required, after 24 hours (Shinohara et al, 2004;Rossi-Schneider et al, 2007;Jain et al, 2010;Melo Nunes et al, 2010). It acts by blocking the nerve endings through the release of gamma amino butyric acid (GABA) leading to palsy and death of the parasite (Shinohara et al, 2004).…”
