咽侧壁憩室最常见类型是咽粘膜穿过甲状舌骨膜与会厌谷在同平面的梨状窝的前外侧壁凸出形成。甲舌膜没有软骨或骨的支持,相对薄弱,咽中缩肌和咽下缩肌并不完全覆盖它,喉上血管与喉内神经穿过该区。另一处潜在薄弱部位是咽会厌皱襞,粘膜可通过这些部位膨出。当然,最常见的咽薄弱处还是在咽后壁,可形成Zenker氏憩室。本病临床表现主要是吞咽困难、声嘶、食物返流。其它如随空气压力而张缩的憩室可在颈部形成时隐时现的包块,细心观察即可诊断。确诊则靠憩室充气、吞钡或气钡造影。有时用探针可 The most common type of pharyngeal wall diverticulum is pharyngeal mucosa through the thyroid hyoid membrane and epistaxis in the same plane of the popliteal anterior lateral wall bulge formed. Amygdala without cartilage or bone support, relatively weak, pharyngeal constrictor and swallow constrictor does not completely cover it, the laryngeal blood vessels and laryngeal nerve through the area. Another potential weakness is pharyngeal epiglottis, through which mucous membranes bulge. Of course, the most common throat weakness is still in the posterior pharyngeal wall, can form Zenker’s diverticulum. The clinical manifestations of the disease is mainly dysphagia, hoarseness, food reflux. Others, such as with the air pressure and contraction of the diverticulum can be formed in the neck when the hidden mass, careful observation can be diagnosed. Confirmed by the diverticulum inflatable, barium or barium gas imaging. Sometimes with the probe can be
