Introduction
the vestibular analyzer varies in different vertebrates, both in terms of size and shape. The differences in shape are dictated by the specificity of the movement of the respective animal.
in this presentation, we will make a literature review and show our clinical experience in a patient with a totally obliterated lateral semicircular canal (changed shape) and still functioning vestibular perception.
materials and methods.
a patient who, after a traffic accident, suffered a head injury with subsequent stenosis of the external auditory canal. The secondary iatrogenic cholesteatoma that developed led to vertigo attacks during pressure (fistula test). The patient was referred for surgical treatment - mastoidectomy. Intraoperatively after removal of the cholesteatoma, the lateral semicircular canal was totally obliterated.
results.
postoperatively, the patient had preserved vestibular function (hypofunction) during a rotatory test for the lateral semicircular canal and preserved (normal) function of the remaining semicircular canals.
discussion.
the author of the presentation will present his theory about this phenomenon, illustrate the process of functioning of the receptor cells in the membranous ampulla of the lateral semicircular canal in a totally obliterated lateral semicircular canal and explain the hypofunction during the rotatory test of the lateral semicircular canal.
