title: [The significance of the valve mechanism in pathology of laryngocele].
abstract: We have described a case of pneumolaryngocele (saccular cyst), which was occurred as a tumor on patient's neck only after performating by him Valsalva maneuver, so it looked like inflating a balloon. The tumor was visible about one hour and then gradually and very slowly disappeared (collapsed), what had approved existence of valve mechanism in a pedincule of the laryngocele. We believe that the valve mechanism offers a feasible explanation of the pathomechanism of laryngocele. Long laryngeal saccule obstructed by the valve mechanism (air can pass only in one direction) and changes of an air pressure in a respiratory tract can due to cystic dilation of the more superior part of the saccule and in consequence, it causes developing of laryngocele.
