“…Poor oral hygiene accompanied by incapability to close the mouth properly was listed as the cause for onset of myiasis. C. bezziana was found responsible for oral myiasis in a 70-year-old female from India with extensive necrotic oral lesion burrowing into the hard palate through which numerous live maggots were seen emerging (Aggarwal et al 2014). The same fly was found to be responsible for causing other extreme cases of oral myiasis from India (Maheshwari and Naidu 2010;Joseph et al 2014) and from Malaysia (Lee 1985).…”

Myiasis, the infestation of tissues of live humans and other vertebrate animals with dipteran larvae (maggots), is a phenomenon of widespread occurrence throughout the tropical regions of the world. It is commonly seen in domestic and wild animals but occurs rarely in man also. The tissue invasion in man by maggots is generally a well-recognized complication of neglected wounds. The condition may be asymptomatic but occasionally results in more or less severe problems and even death when larvae invade body cavities or areas that forbid their direct visual examination. Many cases of myiasis, however, usually do not reach the attention of medical practitioners because of the tendency of the mature larvae to migrate out of the lesion for pupation. In the present study, the authors reviewed the past literature describing the cases of human myiasis, causative fly species and predisposing factors for the onset of the same. The aim of the present manuscript is to provide a database for the future reference of medical entomologists, medical practitioners and veterinarians. Review of literature revealed that 37 fly species belonging to ten families were responsible worldwide for the onset of human myiasis. The incidence of myiasis among humans can be correlated to increasing fly populations, poor hygienic conditions and presence of domestic animals in the close vicinity. Other factors responsible for myiasis include neglected open wounds and foul-smelling discharge from natural body openings. Moreover, ignorance plays a key role in its occurrence since people are generally unaware about the actual cause and often correlate the condition to their superstitious beliefs. It is emphasized that the patients should not neglect their wounds and should take proper medical care; otherwise, myiasis may supervene.

Oral and maxillofacial myiasis in older adults showed low incidence and good prognosis of cure, when there were no systemic complications. Weakness, frailty, dementia, oral lesions, labial incompetence, poor oral hygiene, and bad breath were associated with this disease in reported cases. Preferential therapy choices were debridement alone or combined with Ivermectin. In this case report, debridement and Ivermectin prescription was an effective therapy for an older adult with severe Alzheimer's disease.

“…In Brazil, Cochliomyia hominivorax is the most common causal agent, and is reported in the literature as the species responsible for the most serious cases of human cavitary myiasis in the modern world [2,8]. Factors such as poor sanitation, low income, alcoholism and mental disorders are associated with as aggravating factors in the onset of this condition [4,5]. In this case, the patient was 58 years old and was schizophrenic and an alcoholic.…”

“…Surgical debridement promotes healing, but some adverse reactions may occur in the body, such as in the case when larvae remain in the surgical site due to incomplete mechanical removal [5]. Ivermectin can cause interactions with other drugs and change the concentration of drugs routinely used by patients, as for example in the treatment of chronic diseases, such as in crisis prevention in patients with cerebral palsy.…”

“…When associated with local factors, such as poor sanitation and animal husbandry in rural areas, the likelihood of the manifestation of this condition increases. Other predisposing factors are reported in the literature, including psychiatric disease, hospital infection, drug addiction, mouth breathing, lip incompetence, senility, alcoholism, mental retardation, facial trauma and carcinoma [3][4][5].…”

OBJECTIVE: The word "myiasis" is derived from the Greek myio (fly) and ase (disease), and describes the infestation of humans and vertebrate animals by the larvae of flies, which feed on healthy or dead tissues of the host. The diagnosis is clinical, based on the presence of worms, and its treatment consists of the total removal of these larvae. The authors report a case of surgical debridement as a safe alternative for the treatment of cavitary myiasis in the face. CASE DESCRIPTION: The patient, a 58-year-old male, was admitted with a cavitary lesion on the face of the right side containing fly larvae. Surgical debridement was performed in two phases, with no use of drugs or less invasive maneuvers. Total remission of the condition was achieved, but the patient died due to a squamous cell carcinoma in the posterior region of the tongue and oropharynx, a month and a half after beginning oncologic treatment. CONCLUSION: The use of antiparasitic medication is controversial in the literature, as in specific situations this may put the patient's life at risk. Prevention is still the best way to combat an infestation by myiasis. The authors report a case of myiasis cavitation in the face using only surgical debridement as treatment.Key words: Myiasis; Debridement; Stomatology; Oral surgical procedures Tratamento de miíase cavitária em face: um relato de caso RESUMO OBJETIVO: A palavra "miíase" é derivada do grego myio (mosca) e ase (doença), e descreve a infestação em humanos e animais vertebrados vivos por larvas de dípteros, no qual se alimentam de tecidos sadios ou mortos do hospedeiro. O diagnóstico é clinico com base na presença dos vermes, e seu tratamento consiste na remoção total destas larvas. Os autores relatam um caso de desbridamento cirúrgico como opção segura para o tratamento de miíase cavitária em face. DESCRIÇÃO DO CASO: Paciente, 58 anos, sexo masculino, foi admitido com lesão cavitária em face do lado direito contendo larvas de mosca. Foi realizado desbridamento cirúrgico em duas fases, sem associação de medicamentos ou manobras menos invasivas, com a remissão total do quadro, no entanto o paciente faleceu após um mês e meio do início do tratamento oncológico devido a um carcinoma de células escamosas na região posterior de língua e orofaringe. CONCLUSÃO: A utilização de medicamentos antiparasitários é controversa na literatura, que em situações específicas, podem colocar o paciente em risco de vida. Prevenção ainda é a melhor maneira de combater a infestação por miíase. Os autores relataram um caso de miíase cavitária em face utilizando somente o desbridamento cirúrgico como tratamento.
