Abstract
Aim: study of the characteristics of the acoustic stapedius-muscle
reflex in conjunction with the data of threshold tone audiometry in
combatants with different dynamics of the course of sensorineural hearing
loss.
Materials and methods: The characteristics acoustic stapedius-muscle
reflex and the indicators of threshold tonal audiometry in combatants with
different dynamics of sensorineural hearing loss were conducted. 60 military
personnel were examined: group 1, with positive dynamics after treatment,
group 2, in which progression sensorineural hearing loss took place, 30
people per group.
Results and discussion: The study showed that patients who received
combat acutrauma showed significant changes in the qualitative and
quantitative characteristics of the acoustic stapedius-muscle reflex, which
may indicate that they have disorders in the brainstem of the auditory
analyzer. In patients with progressive sensorineural hearing loss, these
disorders are more pronounced. Thus, they observed a significant (p<0.01)
decrease in amplitude not only compared to the control, but also with the
indicators of the group with positive dynamics. In addition, in the group
with progressive course (group 2) there is a greater "dissociation" of
acoustic stapediusmuscle reflex – a larger number of patients with no
acoustic stapedius reflex, "asymmetric" acoustic stapediusmuscle reflex.
When examining patients with combat acutrauma, we recommend examining both
the peripheral (according to threshold tonal audiometry) and brainstem
(according to acoustic stapedius-muscle reflex) department of the auditory
system, which will not only identify disorders and prescribe the necessary
treatment, but also assess the severity and predict the course of disorders
in such patients. Therefore, acoustic stapedius-muscle reflex and its
amplitude indicators should be used as diagnostic and prognostic criteria
when conducting expert examinations of this category of patients.
Conclusions:
1. In combat acutrauma there are violations both in the peripheral
department of the auditory analyzer according to the threshold tonal
audiometry, and in the central (brainstem) according to acoustic stapedius-muscle
reflex.
2. In combat acutrauma there is a significant (p<0,01) decrease in the
amplitude of acoustic stapediusmuscle reflex, more pronounced in fighters
with progressive SNP.
3. "Asymmetry" of acoustic stapedius-muscle reflex, pronounced decrease in
the amplitude of the acoustic reflex, "dissociation" of acoustic reflex
indicators with the results of audiometric examination is not only a typical
sign of hearing loss in fighters with acute trauma, but can be a prognostic
marker and one of the criteria disorders in this category of patients.
4. When examining patients with combat acutrauma, it is advisable to study
the characteristics of acoustic stapedius-muscle reflex. |
