Ten patients - six with acute burns, two with old accident or surgical
trauma, and two with cranial carcinoma - experienced extensive full-t
hickness necrosis of the scalp and necrosis or defect of underlying sk
ull bone. Microsurgical free flaps were used for the repair. Four lati
ssimus dorsi, two rectus abdominis, one greater omentum, one prefabric
ated omentum-cutaneous flap, and two vascularized outer-table of the c
ranial bone flaps were used with complete survival. The heat-devitaliz
ed cranial bone covered by living tissue flaps healed well and substan
tial ''regeneration'' of previously necrosed bone was shown by roentge
nogram, bone scan, and histopathological examination in the postoperat
ive follow-up. Choosing an artery with high perfusion, bypassing from
the carotid artery to support a massive free flap, is recommended. (C)
