Various lesions including benign and malignant tumors develop in the temporal bone. Since these lesions are surrounded by compact bones involving critical organs such as internal carotid artery and cranial nerves, considerable experience and techniques are required in surgical treatment and surgical treatments often accompanied by severe sequelae. Thus, treatment plan depends on the type of pathology, size, involved structures, age, health status and patient preference. In general, young healthy patients with small tumors are good candidates for surgery. Patients in poor health or with large tumors may choose to undergo radiation or chemotherapy according to the type of pathology. While several books related to the tumors of temporal bone have been published, these books only refer to the anatomy and/or surgical techniques but not to the other treatment options such as radiotherapy or chemotherapy. The aim of this book is to provide the state of the art of comprehensive management of tumors in the temporal bone for professional otologists, head and neck surgeons, and neurosurgeons.The chapters include not only various surgical techniques but also multimodal treatment including chemotherapy, radiotherapy, chemoradiotherapy and particle therapy. Each chapter will be written by the leading expert in the respective field including otology, head and neck surgery, neurosurgery, medical oncology and radiology.
