OBJECTIVE:

To present results of a retrospective analysis of eighty cases of ethmoid adenocarcinoma. Carcinologic and surgical results of anterior skull base resection via the transfacial approach are presented.

METHODS:

Tumors were classified as 5% T1, 23% T2, 31% T3, 21% T4a and 20% T4b. Thirty-four patients were treated via a paralateronasal approach without skull base resection. Anterior skull bas resections were performed via the transfacial approach for 26 patients and by combined neurosurgical approach for 21.

RESULTS:

Mean follow-up was 4.8 years. Survival rate was 63.4% at 5 years and 57.9% at 8 years. Forty-two patients were alive and disease-free at last follow-up. Three patients were alive with recurrence. The rate of local recurrence was 38.8%. Complications occurred in 20% of the patients who had a transfacial approach. Complications appeared to be less frequent than with the combined approach.

CONCLUSION:

Prognosis is related to local control and could be improved by using skull base resection more systematically. In our experience this can be managed by a transfacial approach with similar carcinological results and less complications than the combined approach.
