Objective To assess the safety and the accuracy of surgical navigation technology in the resection of severe ankylosis of the mandibular condyle with the middle cranial fossa.Methods The CT scan data was transferred to a Windows-based computer workstation,and the patient' s individual anatomy was assessed in muhiplanar views at the workstation.In the operation,the patient and the virtual image were matched by individual registration with the reference points which were set on the skull bone surface and the teeth.Then the real time navigation can be performed.Results The acquisition of the data sets was uncomplicated,and image quality was sufficient to assess the operative result in three cases.The operations were performed successfully with the guidance of real-time navigation.The application of surgical navigation have enhanced the safety and the accuracy of the surgery for bony ankylosis of temporomandibular joint.Conclusions The application of surgical navigation can improve the accuracy and safety of surgical excision of the ankylosed skull base tissue.
