TLDR
Laterality in normal swallowing is demonstrated and will be helpful in determining treatment strategies for the patients with dysphagia.Abstract:
Although anteroposterior projections in videofluoroscopic examination of swallowing (VF) provide clinically important information, the laterality of swallowing in healthy subjects has not been examined fully to date. One hundred sixty-seven healthy volunteers were prospectively studied. The subjects were asked to swallow 5 ml of barium solution three times while X-ray images were taken that showed the pathway of the solution from the pharynx into the esophagus to assess the laterality of swallowing. We classified patterns of swallowing into three types according to passage in the pharyngoesophageal segment as indicated by width: RD (right-side-dominant flow), LD (left-side-dominant flow), and NL (no laterality in flow). Fifty-eight percent of the subjects were classified as NL, 35% as LD, and 7% as RD. The ratio of types in women was NL:LD:RD = 7:2:1. There were no significant differences among the groups according to age. Although classifications in young men (age = 20–30 years) tended to be the same as in women regardless of age, ratios of LD tended to increase with age; 71% of elderly adults (age = 51–75 years) were classified as LD. These results demonstrate laterality in normal swallowing and will be helpful in determining treatment strategies for the patients with dysphagia.read more

TL;DR: A mechanistic mathematical model for aroma release in the oropharynx to the nasal cavity during food consumption is described, allowing calculation of retronasal aroma intensity as a function of transfer and volatility properties of aroma compounds in food matrices and anatomophysiological characteristics of consumers.

TL;DR: It is found that there was no significant relation between swallowing laterality and the severity or prognosis of swallowing difficulty in hemiplegic patients with stroke or after their first stroke.

TL;DR: Patients with acute ischemic stroke, admitted to the emergency room, aged ≥ 70 years, score on the GCS ≤ 14, anterior circulation infarct and dementia should be prioritized for swallowing assessment and rehabilitation.

TL;DR: When comparing elderly with non-elderly adult subjects, there is a modification of the acoustic pattern of swallowing, regarding both consistency and food bolus volume.

TL;DR: The area of post-swallow pharyngeal residue was associated with volume, with limitations in specific cases, and direct measurement of pharynGEal residue volume and swallowing physiology with 3D-CT can be used to validate results from standard 2D instrumentation.

TL;DR: The hypothesis of reduced muscular reserve in the swallows of older men as compared to younger men is supported and the potential for exercise to improve reserve is discussed.

The benefit of head rotation on pharyngoesophageal dysphagia.
TL;DR: It is concluded that head rotation can improve swallowing in patients with unilateral oropharyngeal dysphagia, and two potentially beneficial effects were observed: functional exclusion of the relatively flaccid, weakened pharyngeAL wall, and reduced UES tone.

TL;DR: The data indicate that specific sites in the motor cortex and other cortical and subcortical areas are activated with swallowing tasks and that hemispheric dominance is a feature of swallowing under these conditions.
