In addition to surgery and antibiotics, hyperbaric oxygen therapy may be useful and acts to inhibit the growth of and kill the anaerobic bacteria. [10] Multiple wound debridement may be required in cases with extensive tissue involvement. Simple reconstructive procedures following wound debridement yield satisfactory outcomes in majority of the ...
