Objectives: The purpose of this study is to evaluate the effectiveness of skull base surgery on local control and survival of skull base lesions. In addition, the complications and their impact on the tumor control status as well as
postoperative
morbidity are considered. Materials and Methods: We report our experience on 35 patients with skull base lesions. The patients were divided into two subgroups : (1) anterior skull base group (n=27) and (2) middle skull base group (n=8).
Results: For the anterior skull base group, the overall survival rate for malignant tumor (n=15) at 16 months was 53% without regard to histologic types. The overall operative mortality rate was 0% and the complication rate was 25% with
craniofacial resection for control of neoplasm (n=20) and all of these complications were managed successfully without any sequelae. The technique of craniofacial resection was applied to the management of skull base trauma (n=4) and
encephaloceles
(n=3) successfully. The middle skull base group consisted of 5 patients with juvenile nasopharyngeal angiofibroma, and one patient each with malignant meningioma, meningioma, fibrous dysplasia, respectively. All JNA patients were managed with a
combined
intracranial and transmaxillary/transpalatal approach. Among them, 4 patients were cured and one patient developed a recurrence near the cavernous sinus. Surgical morbidity was minimal and there was no mortality. Facial translocation approach to
the
skull base was utilized in 2 patients. Conclusion: Craniofacial resection is a valid surgical technique for surgical management of tumors involving the anterior skull base and also can be applied to the treatment of selected trauma and
malformations. The combined intracranial and transmaxillary/transpalatal approach is a safe and reliable method to remove nasopharyngeal angiofibroma with intracranial invasion.
