Multilevel upper airway surgery for obstructive sleep apnea (OSA) has been shown to cause clinically significant dysphagia in some patients. We describe the cases of 2 adults with OSA who developed persistent dysphagia after multilevel upper airway surgery. Patient-specific computational analysis of swallowing mechanics (CASM) revealed absent pharyngeal shortening and aberrant tongue base retraction in both patients. These findings are consistent with the OSA surgical goal of enlarging the hypopharyngeal airway but likely contributed to our patients' dysphagia. Patient-specific CASM allows for sensitive identification of swallowing mechanical dysfunction that might otherwise be overlooked, and it may be utilized in future head and neck surgery patients to analyze swallowing dysfunction associated with treatment.
对于阻塞性睡眠呼吸暂停（OSA）的多级上气道手术已被证明在一些患者中会导致临床上显著的吞咽困难。我们描述了2例患有OSA的成年人在多级上气道手术后出现持续性吞咽困难的病例。针对患者的吞咽力学计算分析（CASM）显示，两名患者均存在咽部缩短缺失和异常的舌根后缩。这些发现与扩大下咽气道的OSA手术目标一致，但可能是导致我们患者吞咽困难的原因。针对患者的CASM能够敏感地识别可能被忽视的吞咽机械功能障碍，并且未来可用于头颈外科手术患者，以分析与治疗相关的吞咽功能障碍。
