Vertigo, Nausea, Tinnitus and Hypoacusia Due to Head and Neck Trauma

Presented in this volume is the state of the art in the field of neurootology for clinical investigators as well as medical doctors. There are two main themes, the first of which is related to investigation methods: Objective and Quantitative Equilibrium Tests, and the second to an outstanding clinical problem: Vertigo, Nausea, Tinnitus and Hypoacusia due to Head and Neck Trauma. The symposium on the most recent investigative developments was organized in honour of Prof.Dr. Pedro Luiz Mangabeira Albernaz who introduced a special method of triangular electronystagmographic derivation. Clinically, these proceedings cover the mechanisms and the sequalae of head and neck trauma. General aspects, as well as the epidemiology of neurootological findings resulting from this trauma are discussed; functional clinical aspects and changes in evoked potentials and EEG due to concussional trauma are analysed; audiovestibular and taste and smell disturbances elucidated, including psychological features; and finally various aspects of treatment are presented and debated.
