The book provides a comprehensive discussion on the diagnosis and treatment of Eagle Syndrome, drawing on the clinical expertise of the authors. Eagle Syndrome, also known as Symptomatic Styloid Process Elongation, is a rare clinical condition that presents with various manifestations that often go unnoticed in many affected patients for extended periods. Its impact on patients' lives can be severe and occasionally life-threatening, compounded by prolonged frustration due to an ongoing and undiagnosed condition with no apparent solutions. The crucial factor in identifying this clinical entity is acknowledging its existence and considering it in the differential diagnosis during routine practice. In most cases, a detailed medical history, a standard ENT examination, and basic imaging are sufficient. Upon a confirmed diagnosis, a wide array of potentially effective conservative and surgical treatments becomes available. Unfortunately, the global literature primarily consists of individual or limited case reports, with few comprehensive overviews and no dedicated monographs. This fragmented clinical expertise and scientific output likely reflect the overall low awareness and knowledge of the syndrome within the medical community, spanning from general practitioners, ENT specialists, to neurologists, and oral surgeons. The present book fills this existing gap and critically review the extensive but scattered literature worldwide, striving to construct a robust and credible database of available scientific evidence. The volume encompasses intricate carotid and jugular subtypes and covers various forms of open styloidectomies, alongside the latest options in trans-oral approaches, such as 3D endoscopic and robotic techniques. It includes numerous case reports featuring diverse imaging, surgical images, and video clips. Therefore, it will be a valuable resource primarily for ENT and Head & Neck Surgeons, Neurologists, Neurosurgeons, Oral Surgeons, and Pain Specialists alike.
