[Vertical nystagmus].

The review article provides a definition and classification of different nystagmus types, a comparative description of the central and peripheral vestibular nystagmus. The pathogenetic patterns of up-beating and down-beating nystagmus are accurately described. The features of nystagmus formation in various diseases are discussed, such as Wernicke encephalopathy, Arnold-Chiari anomaly, spinocerebellar ataxia and vestibular migraine.

[Tinnitus: clinical and pathogenetic aspects].

The article discusses the pathogenetic and clinical features of tinnitus. It is emphasized that various causes contribute to the appearance of tinnitus, including somatic diseases, excess body weight, iatrogenies, otological diseases with an outcome in hearing loss. The anatomical and physiological features of the structure of the central part of the auditory system are considered.

[Positional vertigo variant].

The article describes case history and multiphase treatment of the patient with attacks of vertigo, initially regarded as the onset of Meniere's disease, but later qualified as secondary positional attacks with combined musculoskeletal pathology of the craniovertebral region and temporomandibular joint. Medicinal, local and surgical treatment led to the perfect result. Thus, the team work of neurologist, otolaryngologist, maxillofacial surgeon and orthodontist led to the successful elimination of vertigo attacks.

[Comprehensive treatment of Costen syndrome].

Objective: To develop an integrated therapy for the combination of pain syndrome and cochleovestibular syndrome (CVS) in patients with temporomandibular joint (TMJ) dysfunction.

Material And Methods: Forty-five patients (42 women and 3 men), aged from 23 to 54 years, with TMJ dysfunction, signs of CVS and complaints of pain in the ear area were stratified into three groups (15 patients each). Patients received pharmacological and osteopathic therapy (group 1); splint therapy followed by orthodontic treatment (group 2) and a combination of the abovementioned methods (group 3).
