Abstract
Dural arteriovenous fistulas (DAVFs) are rare vascular abnormalities that can present with diverse neurological symptoms. We report a case of a woman in her early 60s who presented with pain in the left ear and dizziness. Neurological evaluation and imaging studies revealed a DAVF in the left cerebellopontine angle. This case underscores the importance of considering DAVF as a potential etiology in patients presenting with atypical otological symptoms.

Abstract
Glossopharyngeal neuralgia (GPN) is an uncommon facial pain syndrome and is characterized by paroxysms of excruciating pain in the distributions of the auricular and pharyngeal branches of cranial nerves IX and X. Glossopharyngeal neuralgia characterized by otalgia alone is rare. Herein, the authors analyzed 2 patients with GPN with otalgia as the main clinical manifestation. The clinical features and prognosis of this rare group of patients with GPN were discussed. They both presented with paroxysmal pain in the external auditory meatus and preoperative magnetic resonance imaging suggested the vertebral artery were closely related to the glossopharyngeal nerves. In both patients, compression of the glossopharyngeal nerve was confirmed during microvascular decompression, and the symptoms were relieved immediately after surgery. At 11 to 15 months follow-up, there was no recurrence of pain. A variety of reasons can cause otalgia. The possibility of GPN is a clinical concern in patients with otalgia as the main complaint. The authors think the involvement of the glossopharyngeal nerve fibers in the tympanic plexus via Jacobson nerve may provide an important anatomic basis for GPN with predominant otalgia. Surface anesthesia test of the pharynx and preoperative magnetic resonance imaging is helpful for diagnosis. Microvascular decompression is effective in the treatment of GPN with predominant otalgia.

Abstract
The skull base (SB) is the osseous foundation of the cranial vault. It contains many openings that allow communication between the extracranial and intracranial structures. This communication is crucial in normal physiologic processes yet may also arrow spread of disease. This article provides a comprehensive review of SB anatomy including important landmarks and anatomic variants relevant to SB surgery. We also illustrate the diverse pathologies affecting the SB.
