    Abstract:
    This paper presents treatment strategies for orbital necrotizing fasciitis (NF) in a case of a 33-year-old male diagnosed with orbital NF, which developed after dental root canal treatment. Although orbital NF is rare, it is rapidly progressive and can easily lead to the loss of tissue and visual function, sometimes to a life-threatening extent. Prompt and adequate treatment has been a challenge yet remains quite essential. In addition to the conventional approach to NF, such as immediate antibiotic administration and drainage, orbital NF patients like this case were often treated by incorporating additional steps, which include: 1) performing minimally invasive but adequate removal of necrotic tissue through intraoperative use of ultrasound equipment and postoperative use of proteolytic enzyme-containing ointment for chemical debridement; 2) managing intraorbital pressure by lateral cantholysis and orbital floor removal (decompression); and 3) maintaining the aerobic conditions of the wound after surgical drainage via orbital wall removal. Thus far, satisfactory results in patients with extensive NF of the orbit, including the presented case, were achieved with regards to preserving periorbital tissues, vision, and ocular motility through a multidisciplinary approach. These should be considered as optional means of preserving the orbital tissue and visual function.
