[Clinical experience of resection for nasal skull-base tumors by microsurgical-assisted technique].

OBJECTIVES

To investigate the application of the microsurgical treatment in nasal skull-base tumors resection.

METHODS

In a retrospective study, totally 15 cases with tumors in the nasal skull-base received microsurgical-assisted treatment in our department from February 2012 to June 2017 were analysed. Lateral rhinotomy approach was carried out in 11 patients and posterior wall of the maxillary sinus approach in 4 patients.

RESULTS

Tumors of all cases were completely resected under the microscope. Postoperative bleeding, cerebrospinal fluid leakage, infection and meningo-encephalocele did not occur in this series. The postoperative follow-up time were 6 months to 5 years. One case lost follow-up, seven cases were survivor of tumor-free. Seven cases had recurrence or metastasis, with one case died and other six alive with tumor.

CONCLUSIONS

Microsurgical-assisted resection for nasal skull-base tumors can obtain clear vision, with high surgical precision and security.
