Vocal cord movement disorders are increasingly recognized in patients with amyotrophic lateral sclerosis (ALS). We describe a patient with limb-onset ALS who developed vocal cord paralysis. A 74-year-old Japanese male consulted our clinic with a 6-month history of weakness in both arms. His family history was unremarkable. There were fasciculations and mild atrophy of the tongue and both arms. In the legs, muscle strength was almost normal but widespread fasciculations were present. All tendon reflexes were hypoactive and pathological reflexes were absent. Thereafter, he developed weakness of the legs and showed increased eating time. Babinski sign was positive bilaterally at this stage. The forced vital capacity dropped from 90% at the initial evaluation to 62% of the predicted value 14 months later. Two years after disease onset, the patient developed aspiration pneumonia with hoarseness and had difficulty clearing his throat of phlegm. Laryngoscopy demonstrated severe vocal cord paresis on both sides, particularly in the abductor muscles possibly leading to obstruction. Tracheotomy was performed because of the risk that the patient could choke to death. A review of the literature suggests that severe impairment of vocal cord abduction could be a prelude to sudden death in ALS. Follow up by laryngoscopic examination is necessary.

(1) To examine the association between vocal fold paresis/paralysis (VFP) and poor swallowing outcomes in a thoracic surgery cohort at the population level, and (2) to assess utilization of ENT/speech-language pathology intervention in these cases. The National Inpatient Sample (NIS) represents a 20% stratified sample of discharges from US hospitals. Using ICD-9 codes, discharges undergoing general thoracic surgical procedures between 2008 and 2013 were identified in the NIS. Sub-cohorts of discharges with VFP and those who utilized ENT/SLP services were also identified. Weighted logistic regression models were used to compare binary outcomes such as dysphagia, aspiration pneumonia, and other complications; generalized linear models with generalized estimating equations (GEE) were used to compare total hospital costs and length of stay (LOS). We identified a weighted estimate of 673,940 discharges following general thoracic surgery procedures. The weighted frequency of VFP was 3738 (0.55%). Compared to those without VFP, patients who discharged with VFP had increased odds of dysphagia (6.56, 95% CI 5.07-8.47), aspiration pneumonia (2.54, 95% CI 1.74-3.70), post-operative tracheotomy (3.10, 95% CI 2.16-4.45), and gastrostomy tube requirement (2.46, 95% CI 1.66-3.64). Discharges with VFP also had a longer length of stay and total hospital costs. Of the discharges with VFP, 15.7% received ENT/SLP intervention. VFP after general thoracic procedures is associated with negative swallowing-related health outcomes and higher costs. Despite these negative impacts, most patients with VFP do not receive ENT/SLP intervention, identifying a potential opportunity for improving adverse swallowing-related outcomes.

Swallowing dysfunction, which may cause aspiration pneumonia, is one of the most important complications of treatment of traumatic cervical spinal cord injury (CSCI); however, the mechanism of dysphagia is not well understood. No previous studies have reported the association between morphological changes of the soft tissue and dysphagia. We aimed to determine the factors associated with severity of dysphagia after CSCI and elucidate its mechanism. We conducted a prospective analysis of patients with acute traumatic CSCI who were admitted within 2 weeks of the injury. Dysphagia was evaluated using the Dysphagia Severity Scale (DSS) 2 weeks after the injury. The widths of the retropharyngeal and retrotracheal spaces were measured to assess soft tissue damage owing to the injury using sagittal images of computed tomography. We also assessed age, surgery of the injured cervical spine, presence of tracheostomy, osteophyte behind the pharynx, level of injury, and motor score 2 weeks after the injury. A total of 136 persons met our criteria. Given that 44 persons were categorized under grades <5 of the DSS, which were defined as different types of aspirations, the incidence of aspiration was 32%. The multiple regression analysis revealed that age, motor score, tracheostomy, and retropharyngeal space were significantly associated with DSS. Severe paresis, tracheostomy, old age, and swelling of the retropharyngeal space were significantly affected by dysphagia after CSCI. Morphological changes in the pharynx, situated right behind the larynx, after the injury affects the mechanism of dysphagia.
