[Infectious cellulitis of the face complicating injection for esthetic nasolabial sulcus by hyaluronic acid: report of seven cases].

We report a case series of seven patients with bacterial cellulitis of the face complicating a filler injection for cosmetic reason, treated in a university hospital from 2005 to 2012. There were seven women aged 34 to 57 years. Two patients had a deep collection requiring surgical excision combined with antibiotics. Five patients were treated with antibiotics only. In two cases the bacteria was found streptococcus A and in one case Staphylococcus aureus. One patient required hospitalization in an intensive care unit. Only patients who needed surgical treatment showed moderate aesthetic sequelae.
