ObjectiveThis study describes nine 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.Study designThe study was performed in two steps. In the first part, nine cases seen over a period of 10 years at the Emergency Department of Hospital da Restauração in Brazil are reported. In the second part, a literature review on head and neck myiasis was performed in PubMed comprising the period from 1975 to March 2017.ResultsThe case series mainly consisted of male patients in their thirties. The palate was the most commonly affected site. Myiasis was caused by Cochliomyia hominivorax in all patients, who were treated by mechanical removal of the larvae and debridement of necrotic tissue, followed by oral ivermectin. All patients had sequelae resulting from bone destruction.ConclusionsHead and neck myiasis generally affects individuals with poor hygiene habits, drug users, and individuals with neurological and psychosocial disorders. The treatment of choice is mechanical removal of the larvae and surgical debridement combined with oral ivermectin. This study provides interesting information that could help clinicians in the diagnosis and management of this condition.
