Oral Myiasis-A review

Oral Myiasis: A Rare Case Report

“…Oral myiasis is caused by the flies of dipteral which normally develop in decaying tissues (Sheikh et al, 2011). Factors favoring primary oral infection include poor oral hygiene, halitosis and non-closure of mouth for prolonged periods due to varying reasons.…”

“…The disease can be prevented by controlling the fly population and by maintaining good personal hygiene. In this, patients with special needs including patients with mental and/or, physical disability should be well taken care-of (Ramli and Rahman, 2002;Sheikh et al, 2011;Bhagawati et al, 2013).…”

“…Primary myiasis is caused by biophagus larvae which feed on living tissue while secondary myiasis is caused by necro-biophagus flies which feed on dead tissues. Secondary myiasis is more common and is seen in patients with necrotic lesions (Shinohara et al, 2004;Koteswara and Prasad, 2010;Sheikh et al, 2011). Another classification of myiasis categorizes it into the following types: A) Accidental myiasis in which the larvae get ingested along with the food; B) Semi-specific myiasis when the larvae lay on neurotic tissue of the wound; C) Obligatory myiasis which requires living tissues for larvae development; and D) Facultative myiasis which requires neurotic tissues for flies to lay eggs and incubate them (Caissie et al, 2008).…”

“…Based on anatomic sites involved, myiasis is classified as: A) Cutaneous myiasis; B) Myiasis of external orifices; and C) Myiasis of internal organs (Sheikh et al, 2011).…”

Human nasal myiasis caused by Oestrus ovis in the highlands of Cusco, Peru: Report of a case and review of the literature

“…Biophagous larvae feed on living tissue in primary myiasis; however, secondary myiasis involves necrobiophagous larvae feeding on dead tissue [2]. Myiasis can be transmitted directly by deposition of eggs or larvae onto nonintact skin or mucous membranes.…”
