Dizziness - pathogenesis, diagnosis and treatment

100%
Dizziness is a symptom of many diseases. Patients very frequently come with such ailment to the hospital emergency department. It is a state which may last a few seconds or minutes and increase or recede with time. Therefore, the admitted patients frequently cannot assess their own illness in a precise and objective way. The dizziness definition is also quite ambiguous. Dizziness is defined as the sensation of one own’s body movement or spinning and movement of the surrounding. It is very important to record the patient’s medical history since the diagnostic procedure may depend on the symptoms’ character. Dizziness may be a symptom of a serious disease, although it is not easy to find its cause. It appears not only in case of the labyrinth and nervous system disorders, but also in the systemic and functional diseases. Dizziness and balance disorder are the direct cause of admitting one in every thirty patients. The symptom indicated the directly life-threatening disease only within the 3-8.5% of patients (cerebral circulation insufficiency - 6%, cardiac dysrhythmia – 1.5%, brain tumour < 1%). Analyzing the data concerning the problem of dizziness occurrence within the general population, it has been noticed that this symptom has been reported two or three times more frequent by women than by men. Dizzinesses are classified pathogenetically and clinically into labyrinthine and non-labyrinthine, paroxysmal and permanent, acute and chronic. Dizziness is hard to diagnose because the symptoms reported by patients are only their own subjective sensations. The data presented in the article implicate the increasing number of patients with such disorders. Apart from dizziness, the patients complain also about the hearing disorders and nausea, which make their proper functioning impossible. It is inappropriate to start the treatment without knowing the cause. Establishing, on the basis of patient’s medical history and physical examination, whether the dizziness is of peripheral or central origin, is essential for the further diagnosis. After establishing the main diagnosis, the casual and symptomatic treatment is implemented, in some cases - there is a vestibular rehabilitation or even a surgical treatment.
Auriculo-vestibular symptoms are otolaryngological complaints which frequently co-occur with functional disorders of masticatory organ. These symptoms include: earache, plugged ears sensation, sudden hearing impairment, burning pain of the throat, tinnitus, and dizziness. The aim of the study was assessment of co-occurrence of functional disorders of masticatory organ and auriculo-vestibular symptoms, in patients referred for otolaryngological treatment. Forty-two patients aged 24-46 years of both sexes referred for otolaryngological treatment, because of auriculo-vestibular symptoms, were qualified to our study within the framework of research project. After otolaryngological diagnostics (Department of Otolaryngology), these patients were referred for prosthetic consultation to the Department of Dental Prosthetics of Jagiellonian University Medical College. In Otolaryngology Clinic the following specialist examinations were carried out: basic clinical examinations, including otoscopy, tuning fork trials, tonal and verbal audiometry, and tympanometry. These examinations were supplemented with electronystagmometry. On prosthetic consultation, specialist functional investigations of masticatory organ, and electromyographic assessment of the activity of masseter muscles and the anterior part of the temporal muscle, were carried out. Results of the investigation revealed otolarygological causes of the reported symptoms in 30 patients, whereas in 12 patients (out of 42 patients referred for prosthetic consultation), numerous functional disorders of the stomatognathic system were observed. The investigation confirmed the occurrence of functional disorders in patients with auriculo-vestibular symptoms and appropriateness of treatment by a multi-specialist team.
