Direct surgery of the cavernous sinus: patient selection. 
The cavernous sinus is involved either in lesions arising primarily in the sinus or in lesions invading the sinus from surrounding structures.  Experience with direct surgery of the cavernous sinus is encouraging, but no conclusive evidence exists concerning the roles of conservative, surgical, and radiological treatments in terms of effectiveness, morbidity, and long-term results.  Consequently, management is individualized according to the patient and the lesions.  We discuss these factors in patient selection for cavernous sinus surgery.
