Abstract

Introduction: Middle skull base and infratemporal fossa are the most complex anatomical structure and difficult to approach. Tumors in this area are very diverse, located close to other critical neurovascular structures, therefore, surgical approach to remove tumors is always a challenge. Objective: The article review clinical symptoms, radiological images, advantages and disadvantages, outcomes of using the external approach to remove tumors of middle skull base and infratemporal fossa by using external approach at otorhinolaryngology department of Cho Ray hospital. Methods: The study is a cross sectional study to review 16 patients diagnosed with tumor of middle skull base and infratemporal fossa who were treated with external approaches. Data of the patients were collected and analyzed. Results: The study had 12 benign tumors, 4 malignant tumors. We had 14/16 patients were treated with subtemporal - preauricular approaches. 1 case was treated with transcervical approach (Sebilau Carrega). 1 case was treated with transoral transpalatal approach. There was no morbidity and complications were recorded during perioperative stages. Conclusion: The subtemporal preauricular approaches is a gold standard approach to remove the tumor of middle skull base and infratemporal fossa. Combining with other approaches depends on the nature, location and size of the tumor.
