Myasis describes the “infestation of a human or vertebrate being by the larvae of a dipterous that, at least during its development phase, feed on the tissues of the host or the food ingested by it”. There is little prevalence of myasis in human beings. The main clinical manifestation is cutaneous myasis, wounds being the most common target. Exceptionally occurs in the maxillofacial territory.

Objective: Revise the literature and present a case of traumatic myasis in a patient with advanced co-morbidity including his diagnosis, management, treatment and clinical evolution.

Results: A case of traumatic myasis by M. domestica or common fly is presented. It manifested as a result of the untreated deposit of eggs in a fronto orbital wound. A situation of abandonment and comorbidity favoured the development of the condition. Ether 15% was applied; debridement, drainage and irrigation were performed. There was no recurrence of myasis and the wound evolved favourably. The patient died a month after treatment due to secondary respiratory compromise.

Conclusion: The treatment of myasis is specific to the causal species. The success of its treatment depends on the severity and degree of affectation at the moment of the initial evaluation, as well as the general condition of the patient.
