Keywords: cochlear syndrome, sensory neural hypoacusis, primary ischemic insult, early restorative period
Abstarct: Objective - to estimate audition status in patients in early restorative period of primary ischemic insult of light degree. Material and methods. 66 patients aged 37-67 years who were treated after primary ischemic insult of light degree were examined at teaching hospital of Ivanovo State Medical Academy. The diagnostic complex included the collection of complaints, anamnesis, ears, throat and nose examination, audition function evaluation (acumetry, tonal threshold acumetry, audiometry, suprathreshold audiometry). The obtained results were compared with the data of ultrasound duplex scanning of brachycephalic trunks which was performed in acute period of ischemic insult. Results. The main complaints of the patients were as follows: vertigo and unsteadiness while walking, headache, illegibility of addressed speech and buzzing in the ears. The audition decrease were not revealed in 35 (53,0%) examined patients upon the data of tonal threshold audiometry. The signs of hypoacusis were detected in 31 (47%) cases and they were predominantly characterized by unilateral injury according to the type of sound perception of the first degree. Conclusions. Sensory neural hypoacusis were revealed in nearly 50% patients in early restorative period of primary ischemic insult of light degree and each third patient had the first degree of the disorder.
