Abstract

Background: The latency of the swallowing reflex is an important factor causing dysphagia in head and neck cancer patients. Although there are many reports comparing voluntary swallowing function before and after treatment, few studies have focused on the latency of the swallowing reflex, which is a risk factor for pneumonia due to silent aspiration. The aim of this retrospective study was to clarify the changes in the latency of the swallowing reflex before and after treatment.

Methods: The latency of the swallowing reflex was quantified using the time from the injection of 1 ml of distilled water into the pharynx through a nasal catheter to the onset of swallowing.

Results: The latency time of the swallowing reflex was significantly decreased 3 months after treatment compared to before treatment. A significant reduction was also observed in patients with pharyngeal cancer who underwent chemoradiation therapy.

Conclusions: This retrospective study showed that a delayed swallowing reflex improved with treatment in advanced head and neck cancer patients.

Trial registration: The Institutional Review Board of Tohoku University Hospital (Number 2014-1-274).

晚期头颈癌治疗后延迟吞咽反射的改善。

背景:吞咽反射的潜伏期是头颈癌患者发生吞咽困难的重要因素。虽然有许多报道比较治疗前后的自主吞咽功能，但很少有研究关注吞咽反射的潜伏期，这是无声误吸引起肺炎的危险因素。本回顾性研究的目的是阐明治疗前后吞咽反射潜伏期的变化。方法:将1 ml蒸馏水经鼻导管注入咽内至吞咽发生的时间，定量测定吞咽反射潜伏期。结果:治疗后3个月吞咽反射潜伏期较治疗前明显缩短。在接受放化疗的咽癌患者中也观察到明显的减少。结论:这项回顾性研究表明，晚期头颈癌患者的延迟吞咽反射在治疗后得到改善。试验注册:东北大学附属医院机构审查委员会(2014-1-274)。
