It is established that maximum expiratory flow-volume curve coupled with closing volume curve may give important information on obstructive impairment in the laryngectomized patients. In the patients after laryngectomy, the pattern of the flow-volume curve was similar to that found in patients with chronic bronchitis. These abnormalities of the flow-volume curve which became convexity to the volume axis can be reversed at least partially by bronchodilator drug inhalation. It is concluded that the patients after laryngectomy have abnormalities of ventilation distribution despite relatively normal results of routine pulmonary function tests and respiratory resistance.
已证实，最大呼气流量-容积曲线与闭合容积曲线相结合，可为喉切除患者的阻塞性损害提供重要信息。在喉切除术后的患者中，流量-容积曲线的模式与慢性支气管炎患者相似。这些向容积轴凸出的流量-容积曲线异常，可通过吸入支气管扩张剂药物至少部分逆转。得出的结论是，尽管常规肺功能测试和呼吸阻力结果相对正常，但喉切除术后的患者仍存在通气分布异常。
