[Resection tumor of the anterior skull base region with extend external frontal sinus approach].

OBJECTIVE

To study a better surgical approach for the resection of tumor in the anterior skull base and the fronto-orbito-ethmoidal region.

METHOD

Extend external frontal sinus approach was made in the lesion side. The incision can be extended outward to the nasal side or superciliary arch according to the tumors extent and size so as to get a full exposure of tumors of anterior skull base, fronto-orbito-ethmoidal region, or exterior margin of arcola.

RESULT

From January 1998 to December 2003, 28 patients suffered tumors of anterior skull base and fronto orbito-ethmoidal region were received tumors resection through this approach. Postoperatively, no death or recurrence have occurred up to now in 8 cases of benign tumors, and the one-year survival rate was 95% (19/20), the three-year survival rate was 61.5% (8/13), and the five-year survival rate was 57.1% (4/7) in 20 cases of malignant tumors.

CONCLUSION

This approach provide good exposure. Bleeding is little, operation field is clear, operating is easy re-establish skull base is convenience, surgical trauma is small, and reaction is mild when using decohesion tumors and block blood supply in skull base method. We believe this approach is a better method for resection of tumors in anterior skull base and the fronto-orbito-ethmoidal region.
