Thirteen patients with infratemporal fossa malignancies treated in the Sichuan Cancer Hospital from 1988 to 1993 are reported. All cases were treated surgically combined with pre-operative and post-operative radiotherapy with or without chemotherapy. The survival rate of the patients with survival period beyond 2 years was 53.8%. The survival was associated with the extent of dissection (P < 0.01). The operation value, surgical approaches, resection range, bone boundary of surgery, stylohamular line and repair are analysed and discussed.
