Abstract
OBJECTIVE
This study makes an analysis of the effect of Botulinum toxin type A on otitis media with effusion in rats.
METHOD
As part of the study, 24 male Wistar Albino rats were divided into three groups: Group 1: Botulinum toxin Type A and Histamıne (intratympanic 0.2 ml = 20 unit BTA); Group 2: Saline and Histamine (intratympanic 0.2 ml 0.9%); Group 3: Histamine (intratympanic 0.2 ml). Histamine (intratympanic 0.2 ml) was administered into the right ear for all groups. DPOAE and ABR tests were carried out on days 5, 10, 15 and 20 from the beginning of the study.
RESULTS
There was no significant difference between DPOAE and ABR scores of the groups. In each group, the DPOAE scores for the right ear significantly decreased on day 5 when compared to the basal scores. In each group, there was no significant difference between days 5, 10 and 15 for the right ear.
CONCLUSIONS
Botulinum toxin type A blocked the secretion of glands in the middle ear and showed no effect to prevent the formation of serous otitis. In addition, it was found out that Botulinum toxin did not lead to any morphological change in the cochlea.
