    Introduction:

    Piston prosthesis is usually placed during the stapes surgery. In temporal bone experiments vestibular displacement of the piston could be provoked by pressure changes in the middle ear. Such displacement might result in irritation and/or damage of the vestibular system and the inner ear. Aim of this prospective study was to evaluate vestibular function after stapes surgery due to atmospheric pressure changes.

    Methods:

    Patients, who underwent stapes surgery between Nov.2015 and May 2017 for otosclerosis, were consecutively included in this study. Tonaudiometry, tympanometry, caloric vestibular testing incl. video nystagmography (VNG), cervical and ocular vestibular-evoked myogenic potentials (c- and o-VEMP) and posturography were carried out before, as 6 weeks and 3 months after the surgery. Pressure changes (over- and underpressure) were simulated combining tympanometry with VNG and posturography.

    Results:

    17 patients with a complete follow-up were included. All patients have not revealed vertigo during the follow-up. Pressure changes did not affect the VNG or posturography in any of the patients after the surgery.

    Conclusions:

    In this prospective trial no affection of the vestibular system was evident after the stapes surgery. Furthermore, atmospheric pressure changes, which were provoked by tympanometry, did not affect significantly the vestibular system.
