СЛУЧАЙ РЕДКОЙ ФОРМЫ ДОБРОКАЧЕСТВЕННОГО ПАРОКСИЗМАЛЬНОГО ПОЗИЦИОННОГО ГОЛОВОКРУЖЕНИЯ, СВЯЗАННОЙ С ПАТОЛОГИЕЙ ГОРИЗОНТАЛЬНОГО ПОЛУКРУЖНОГО КАНАЛА

Introduction: The most common causes of an acute attack of vertigo are: benign paroxysmal positional vertigo (BPPV), vestibular neuronitis, migraine, Meniere’s disease, orthostatic hypotension. In the pathogenesis of BPPV, one of the most common causes of an acute attack of vertigo is the pathology of the posterior semicircular canal (80%), BPPV of the horizontal semicircular canal are much less common. Diagnosis and treatment of this pathology is dependent on which of the semicircular canals are affected. Purpose: to show the features of diagnosis and evaluate the effectiveness of conservative methods of treatment of BPPV of the posterior and horizontal semicircular canals using repositional maneuvers. Materials and methods: An analysis was made of 13 patients with BPPV who contacted the Consultative and Diagnostic Department of JSC National Centre for Neurosurgery within 6 months in 2019. The analysis showed that the number of female patients prevails over the males: 83%. The average age is 51.4 years. The second most common symptom in patients with BPPV after dizziness is a feeling of nausea (75%). In 84.6% of patients, an acute episode of dizziness began in the morning. Only 2 out of 13 patients went to the doctor during the first 10-15 days, and 2 patients regularly and conscientiously visited the doctor. There was an improvement in 5 cases, and complete recovery and relief of dizziness occurred in 2 patients. A rare case of BPPV associated with pathology of the horizontal channel is presented to the attention of readers. Results: The use of diagnosis and treatment of BPPV of the horizontal semicircular canal proves the importance of correct and timely diagnosis of this disease and the high efficiency of repositional maneuvers. Conclusion: it is especially important in case of BPPV to determine the side of the lesion and localization: the posterior semicircular canal or the horizontal semicircular canal, since treatment tactics and the choice of repositional maneuvers depend on this. The treatment of DPPV with the use of repositioning maneuvers is highly effective and easy to carry out. [ABSTRACT FROM AUTHOR]
