In this article, we report on two cases of gas-forming necrotising fas
ciitis of the neck admitted to our university hospital. In both patien
ts, large gas-forming abscesses were detected by CT scan. Microbiologi
c smears revealed a mixed flora of aerobic and anaerobic bacteria, pre
dominantly anaerobic streptococci. Emergency surgery with debridement
and drainage, appropriate antibiotic therapy, and intensive care were
performed. One 58-year-old patient with no concommittent disease recov
ered well after fourteen days. The other 71-year-old patient with diab
etes mellitus and renal insufficiency died despite adequate therapy as
a result of metabolic disturbances.
