The mucosal waves on the vibrating vocal folds may move in anterior-posterior, mediolateral and in caudal-cranial direction. This article discusses the possible significance of the vertical movement from the point of view of mechanical stress in phonation and the formation of vocal fold traumas. It is hypothesized that in certain conditions the vocal folds may behave in cranial direction like a quasi-free end of a long lash producing very rapid vibratory waves (e.g. the waves in a whiplash). This could be detrimental to the tissue structure. The role of phonation type in enhancing/diminishing this effect will also be discussed.
振动声带的黏膜波可在前后、内外侧以及尾颅方向移动。本文从发声时的机械应力以及声带创伤形成的角度探讨垂直运动的可能意义。据推测，在某些情况下，声带在颅向的表现可能类似于长鞭梢的准自由端，产生非常快速的振动波（例如鞭打时的波）。这可能对组织结构有害。还将讨论发声类型在增强/减弱这种效应方面的作用。
