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 and outcomes of surgical approach to remove JNA tumors with middle cranial fossa and cavernous sinus extension. Pathway for tumor invade the the middle cranial fossa and its incidence at otorhinolaryngology department of Cho Ray hospital. Methods: The study is a case series to review 05 patients (ages 13 to 28) diagnosed with JNA tumor with intracranial extension from 2018 – 2021. Results: All 5 patients with JNA was diagnosed with stage III. All of them were treated with Degloving approach and Preauricular Subtemporal Infratemporal Fossa approach or combining those techniques. Endoscopic surgery was used as additional technique. Follow up was 2 years. Conclusion: Tumor can invade middle cranial fossa and cavernous sinus through natural fissure and foramen, most commonly is superior orbital fissure. Due to high risk of complications and recurrence, the extensive tumor should be treated by a multidisciplinary team and modern techniques.
