Abstract:
Objective To evaluate the application of computer-aided design and navigation technology in skull base and infratemporal fossa tumor surgery and to analyze its advantages and disadvantages.Methods Twenty-nine cases with tumor of skull base and infratemporal fossa were treated with computer-aided design and navigation surgery.The Parameters of age,gender,primary or recurrent tumor,tumor nature and surgical approach were recorded.Results En bloc resection was performed in 20 cases and subtotal resection in 9 cases.The margin status was negative margin in 8 cases,near-tumor margin in 17 cases and positive resection margin in 4 cases.Postoperative complication rate was 14％ (4/29).During the follow-up period,2 benign cases recurred.In the malignant group,there were 7 cases of recurrence,2 cases of metastasis and 3 deaths.The 5-year overall survival and progression-free survival rate were 69％ and 40％ respectively.Conclusions Navigation technology can enhance the confidence of the surgeons and operation safety in handling malignant tumors in skull base and infratemporal fossa.
