Abstract

Abstract:

Objective With the assistance of 3D visualization and real-time navigation technologies, the tumors in the parapharyngeal and lateral skull base should be removed through oral the approach with endoscopy. Methods The preoperative CT data of eight patients with parapharyngeal or lateral skull base soft tissue tumors were modeled, and the anatomical position relationship between the tumor and surrounding blood vessels and other important structures was reconstructed using 3D visualization technology, and preoperative design was performed. The intraoperative oral approach and real-time navigation guidance were adopted in the endoscopic resection of soft tissue tumors in the parapharyngeal and lateral skull base, and the clinical application value of this method was evaluated. Results The blood loss during the operation was controlled within 150 mL, and the average blood loss was approximately 125 mL. The incidence of postoperative complications was low, and patients could recover well through functional training. The oral approach did not leave any wounds nor scars on the patient’s facial skin after the operation and had no effect on the patient's appearance. Conclusion The combination of 3D visualization technology, intraoperative real-time navigation, and endoscopy provides a beautiful, safe, and minimally invasive surgical method for patients with parapharyngeal or lateral skull base tumors.
