Craniofacial resection for tumors of the nasal cavity and paranasal sinuses.

BACKGROUND AND PURPOSE

Craniofacial resection provides multidirectional approaches to remove nasal and paranasal tumors that involve the skull base. The purpose of this study was to determine the survival and local control rate in patients undergoing craniofacial resection for tumors of the nasal cavity, paranasal sinuses, and adjacent areas.

METHODS

The medical records of 30 consecutive patients who had undergone craniofacial resection for tumors of the nasal cavity, paranasal sinuses, and adjacent areas were reviewed. The extent of disease, treatment results, complications, and prognoses were analyzed.

RESULTS

Lesions were malignant in 28 patients and benign in two. Sixteen of the patients had dural or intradural involvement. There was no surgical mortality, and the rate of surgical morbidity was 7%. The 2-year survival of the 28 patients with malignancies was 46% and the mean follow-up time was 35 months. Local control was achieved in 53% of patients. Nine of 16 patients with dural or intradural invasion had a mean survival time of 17 months. There was no significant difference in the frequency of local control between previously treated and untreated patients. Patients who had a clear margin showed significantly better local control than those with an involved or questionable margin.

CONCLUSIONS

Tumors of the nasal cavity and paranasal sinus that involve the skull base can be effectively treated using craniofacial resection, with a reasonable survival and low complication rate.
