Adjuvant use of collagenase to facial soft tissues reconstruction: Case report with a six-year follow-up

The facial injuries occur more frequently among young male adult, resulting from varied etiology, such as automobile accidents and interpersonal violence. The lesions predominantly affect the frontal region or the facial subunits, reaching hemiface or the entire face, with various levels of severity. This study aims to report a case of severe facial tissues injury involving hemiface and ear avulsion, including the immediate emergency treatment with suture and flap rotation, collagenase use, complementary treatments such as the use of low intensity CO2 laser, hyaluronic acid and botulin toxin. The patient had a satisfactory evolution in a six-year follow-up. Thus, a well-planned treatment for facial restorations and an appropriated combined therapy may bring positive results.
