误吸对患者健康和生活质量的不良后果有充分的记录。人们普遍认为，单侧声带运动障碍患者的误吸概率增加，然而，误吸的发生率和拟议机制因报告的系列而异。我们回顾了通过约翰霍普金斯医院吞咽中心数据库确定的单侧声带运动障碍患者的电影或视频咽食管造影结果，以确定误吸和喉穿透的患病率和原因。分别在38%和12%的患者中发现了误吸和喉部穿透。误吸是由于气道保护功能受损，而不是由于食管阻塞和喉“溢出”。“损伤的数量和程度与吸入的可能性直接相关。阻塞增加了误吸的可能性。视频咽食管造影准确识别有误吸风险的患者。
The adverse consequences of aspiration in regard to patient health and quality of life are well documented. It is generally accepted that the probability of aspiration is increased in patients with unilateral vocal fold motion impairment, however, the incidence and proposed mechanism of aspiration vary depending on the reported series. We reviewed the cine or video pharyngoesophagographic findings in patients with documented unilateral vocal fold motion impairment, identified through the Johns Hopkins Hospital Swallowing Center database, to determine the prevalence and cause of aspiration and laryngeal penetration. Aspiration and laryngeal penetration were identified in 38% and 12% of patients, respectively. Aspiration resulted from impaired airway protection, not from esophageal obstruction with laryngeal "spill-over." The number and degree of impairments directly correlated with probability of aspiration. Obstruction potentiated the likelihood of aspiration. Video pharyngoesophagography accurately identifies patients at risk for aspiration.
