喉气囊肿是一种少见的疾病的异常扩张或球囊喉症的定义，形成一个充满空气腔。
外腔封闭，末端有一个球囊样装置，终止于内腔出口附近。
当采用顺应性材料时所述的顶端球囊可以用于扩张支架。
椭圆囊、壶腹嵴的发生较早，随后才形成球囊，到出生时前庭感觉器官已基本发育成熟。
1·RESULTS Ampullary cristae or macula of saccule and utricle were well differentiated in ED 40. There were a layer of hair cells and several layers of supporting cells.
结果胚胎40 d，豚鼠前庭壶腹、椭圆囊斑及球囊斑已分化，前庭上皮出现一层毛细胞及多层支持细胞；
2·Laryngocele is an uncommon disease defined as an abnormal dilatation or herniation of the laryngeal saccule, forming an air-filled cavity.
喉气囊肿是一种少见的疾病的异常扩张或球囊喉症的定义，形成一个充满空气腔。
3·An amount of water can be injected through an injection port at the position of a handgrip so as to control the size of the saccule.
通过手柄处的注射接口可以注入适量的水以控制球囊的大小。
4·The shapes of utricle, saccule and crista ampullaris tended to mature at E15, and the shapes of supporting and hair cells also tended to mature. The vestibular organ was mature at P0.
到胚胎第15天，椭圆囊、球囊、壶腹峪初具成熟形态，毛细胞和支持细胞也初具雏形，到出生时，前庭器官已基本发育成熟。
5·When the compliant material is used, the top end saccule can be used to expand the bracket.
当采用顺应性材料时所述的顶端球囊可以用于扩张支架。
1·The saccule enlarges and expands gradually over time until it presents as a paralaryngeal or submandibular mass.
小囊可以逐步增大并且随时间扩展直到表现为一个声门旁或下颌下肿块。
