    Relationship
    of the Utriculus and Sacculusto
    the Stapes Footplate: Anatomic
    Implications for 
    Sound and/or
    Pressure-induced Otolith
    Activation.

    Ann Otol Rhinol Laryngol
    108:548-533,1999.

       

    The relative 
    distances between
    structures in the othic capsule and the stapes
    footplate were examined by 130 
    human temporal bone
    sectioned in the vertical plane.Average mean
    distances  fom footplate to the utriculus and
    saccule were tacken in anterior, middle and
    posterior 3rd of the footplate. Important finding
    was of membranous connections extending from
    utriculus to footplate were detected in 26% of 
    temporal bones.These
    connections along with other anatomic factors
    like,hypermobility of stapes or dehiscence of bone
    within labyrinthine structure make patients
    susceptible to sound or pressure induced otolith
    activation thereby suggesting there may be different
    causes for Tullio phenomenon.

       


    These are very important to those  otologic surgeons who do stapedectomies and work within
    critical distances of 1-2mm to otholithic organs.
    This article thus is very helpful to clinician in
    description of the anatomic relationships and
    thereby avoiding potential complications.
