Changes of acoustic variables are related to excision size and site, suggesting the distinctive tongue portion for the articulation of each speech sound. Perioperative rehabilitation could activate the articulators and increase the range of movement of the remaining tongue, especially the preserved anterior tongue.

Summary Dysphagia after esophagectomy is the main cause of a prolonged postoperative stay. The present study investigated the effects of a swallowing intervention led by a speech–language–hearing therapist (SLHT) on postoperative dysphagia. We enrolled 276 consecutive esophageal cancer patients who underwent esophagectomy and cervical esophagogastric anastomosis between July 2015 and December 2018; 109 received standard care (control group) and 167 were treated by a swallowing intervention (intervention group). In the intervention group, swallowing function screening and rehabilitation based on each patient’s dysfunction were led by SLHT. The start of oral intake, length of oral intake rehabilitation, and length of the postoperative stay were compared in the two groups. The patient’s subgroups in the 276 patients were examined to clarify the more effectiveness of the intervention. The start of oral intake was significantly earlier in the intervention group (POD: 11 vs. 8 days; P = 0.009). In the subgroup analysis, the length of the postoperative stay was also significantly shortened by the swallowing intervention in patients without complications (POD: 18 vs. 14 days; P = 0.001) and with recurrent laryngeal nerve paralysis (RLNP) (POD: 30 vs. 21.5 days; P = 0.003). A multivariate regression analysis identified the swallowing intervention as a significant independent factor for the earlier start of oral intake and a shorter postoperative stay in patients without complications and with RLNP. Our proposed swallowing intervention is beneficial for the earlier start of oral intake and discharge after esophagectomy, particularly in patients without complications and with RLNP. This program may contribute to enhanced recovery after surgery.

Background: Dysphagia due to bulbar involvement is a major symptom of patients with spinal and bulbar muscular atrophy (SBMA). The aim of this pilot study was to test the efficacy and safety of the head lift exercise for swallowing dysfunction in SBMA. Methods: We enrolled 6 subjects with genetically confirmed SBMA and instructed them to perform the head lift exercise for 6 weeks. The efficacy outcome measures were the changes from baseline in tongue pressure, the scores of swallowing functional questionnaires, and the motor functional scales and parameters of videofluorography (VF). Results: All subjects completed the study and no major adverse effects were recorded. Tongue pressure significantly increased by 19.2 ± 0.15% (p < 0.05) after the 6-week head lift exercise. The scores for oral dysphagia also improved, although there was no significant change in VF parameters or other variables examined pre- and post-exercise. Conclusion: Our findings suggested that the head lift exercise may improve swallowing dysfunction, particularly tongue pressure, in SBMA.

Dysphagia after esophagectomy is a major risk factor for aspiration pneumonia, thus preoperative assessment of swallowing function is important. The maximum phonation time (MPT) is a simple indicator of phonatory function and also correlates with muscle strength associated with swallowing. This study aimed to determine whether preoperative MPT can predict postoperative aspiration pneumonia. The study included 409 consecutive patients who underwent esophagectomy for esophageal cancer between 2017 and 2021. Pneumonia detected by routine computed tomography on postoperative days 5–6 was defined as early-onset pneumonia, and pneumonia that developed later (most often aspiration pneumonia) was defined as late-onset pneumonia. The correlation between late-onset pneumonia and preoperative MPT was investigated. Patients were classified into short MPT (&lt;15 seconds for males and &lt;10 seconds for females, n = 156) and normal MPT groups (≥15 seconds for males and ≥10 seconds for females, n = 253). The short MPT group was significantly older, had a lower serum albumin level and vital capacity, and had a significantly higher incidence of late-onset pneumonia (18.6 vs. 6.7%, P &lt; 0.001). Multivariate analysis showed that short MPT was an independent risk factor for late-onset pneumonia (odds ratio: 2.26, P = 0.026). The incidence of late-onset pneumonia was significantly higher in the short MPT group (15.6 vs. 4.7%, P = 0.004), even after propensity score matching adjusted for clinical characteristics. MPT is a useful predictor for late-onset pneumonia after esophagectomy.
