Oropharyngeal dysphagia (OD) is very prevalent among poststroke patients, causing severe complications but lacking specific neurorehabilitation treatment. This review covers advances in the pathophysiology, diagnosis, and physiologically based neurorehabilitation strategies for poststroke OD. The pathophysiology of oropharyngeal biomechanics can be assessed by videofluoroscopy, as delayed laryngeal vestibule closure is closely associated with aspiration. Stroke may affect afferent or efferent neuronal circuits participating in deglutition...

With the progress of multidisciplinary vascular anomaly treatment, the use of radiotherapy, cryotherapy, laser therapy and medical treatments, the corticosteroid, sclerotherapy, and many more, the role of surgery has been refined. Surgical treatment has historically been the mainstay of treatment and will maintain.A miniature tourniquet technique applied to the tongue was successfully utilized in reducing bleeding to a minimum during surgical resection of a massive cavernous hemangioma involving the tongue and lower lip without any postoperative complications...

OBJECTIVES/HYPOTHESIS: Aging results in progressive changes in deglutitive functions, which may be due in part to alterations in muscle morphology and physiology. Mastication is a critical component of bolus formation and swallowing, but aging effects on masticatory function have not been well studied. STUDY DESIGN: The purpose of this study was to 1) quantify the effects of aging on mastication, and 2) determine the effects of tongue exercise on mastication in young adult and old rats...

Oropharyngeal dysphagia due to upper esophageal sphincter (UES) dysfunction is commonly encountered in the clinical setting. Selective experimental perturbation of various components of the deglutitive apparatus can provide an opportunity to improve our understanding of the swallowing physiology and pathophysiology. The aim is to characterize the pharyngeal and UES deglutitive pressure phenomena in an experimentally induced restriction of UES opening in humans. We studied 14 volunteers without any dysphagic symptoms (7 men, 66 ± 11 yr) but with various supraesophageal reflux symptoms...

OBJECTIVE: To explore the origin of "physiological" ear clicks during deglutition or other pharyngeal movements, which, in contrast to disturbing frequent clicks under pathologic conditions, mostly remain unnoticed by the patient. STUDY DESIGN: Clinical experimental study at a tertiary referral center. METHODS: Ear clicks were recorded by a microphone sealing the external ear canal parallel to endoscopic or manometric evaluations of the Eustachian tube function...

PURPOSE: Tongue base retraction during swallowing is critical to bolus propulsion in normal physiological swallowing. A better understanding of the hyoglossus and styloglossus, muscles thought to be key to tongue base retraction, will improve the quality of physical rehabilitation in dysphagic patients in addition to preventing iatrogenic damage to structures critical to deglutition. This study utilized muscle functional MRI in healthy adult human subjects in order to determine if the hyoglossus and styloglossus are active during swallowing...

BACKGROUND: Oropharyngeal dysphagia is common after a stroke. Understanding the physiology of swallowing and its coordination with respiration in stroke recovery is crucially important. METHODS: A non-invasive swallowing assessment method was used to detect oropharyngeal swallowing and respiration coordination simultaneously during the swallowing process. This system detected movement of the larynx, submental muscle activity, and nasal airflow. Six different sizes of water boluses (maximum of 20 mL) were swallowed and assessed for each subject...

REVIEW
Josef Finsterer, Wolfgang Grisold
Lesions of the lower cranial nerves (LCN) are due to numerous causes, which need to be differentiated to optimize management and outcome. This review aims at summarizing and discussing diseases affecting LCN. Review of publications dealing with disorders of the LCN in humans. Affection of multiple LCN is much more frequent than the affection of a single LCN. LCN may be affected solely or together with more proximal cranial nerves, with central nervous system disease, or with nonneurological disorders. LCN lesions have to be suspected if there are typical symptoms or signs attributable to a LCN...

Bolus volume has been widely studied, and research has demonstrated a variety of physiological impacts on swallowing and swallowing disorders. Oral perception of bolus volume has not, to our knowledge, been investigated in association with normal ageing processes. Research suggests many sensory changes with age, some within the oral cavity, and changes in swallowing function with age have been defined. The role of perception in oropharyngeal deglutition with age requires further investigation. The purpose of this study was to establish the psychophysical relationship between liquid volume and oral perception and examine changes with age...

Cross-sectional imaging has long been employed to examine swallowing in both the sagittal and axial planes. However, data regarding temporal swallow measures in the upright and supine positions are sparse, and none have employed the MBS impairment profile (MBSImP). We report temporal swallow measures, physiologic variables, and swallow safety of upright and supine swallowing in healthy subjects using videofluoroscopy (VFS). Twenty healthy subjects ages 21-40 underwent VFS study upright and supine. Subjects were viewed in the sagittal plane and swallowed 5 mL liquid and pudding barium...

The term presbyphagia refers to all changes of swallowing physiology that are manifested with increasing age. Alterations in the pattern of deglutition that are part of healthy aging are called primary presbyphagia. Primary presbyphagia is not an illness in itself but contributes to a more pervasive naturally diminished functional reserve, making older adults more susceptible to dysphagia. If disorders in swallowing occur in the elderly as a comorbidity of a specific disease, for example stroke or neurodegenerative disorders, this is called secondary presbyphagia...

Different types of sensors are being used to study deglutition and mastication. These often suffer from problems related to portability, cost, reliability, comfort etc. that make it difficult to use for long term studies. An inertial measurement based sensor seems a good fit in this application; however its use has not been explored much for the specific application of deglutition research. In this paper, we present a system comprised of an IMU and EMG sensor that are integrated together as a single system...

BACKGROUND: Coordination between breathing and swallowing helps prevent aspiration of foreign material into the respiratory tract. The authors examined the effects of anesthesia and hypercapnia on swallowing-breathing coordination. METHODS: In a randomized controlled crossover study, general anesthesia with propofol or sevoflurane was titrated using an up-down method to identify the threshold for suppression of the motor response to electrical stimulation of the forearm...

The objective of this study was to analyse the viscosity effect of liquid Newtonian products on aroma release, taking human physiological characteristics into account. In vivo release of diacetyl from glucose syrup solutions varying widely in viscosity (from 0.7 to 405mPas) was assessed by five panelists using Proton Transfer Reaction Mass Spectrometry (PTR-MS). The physicochemical properties of the solutions and the physiological parameters of subjects were experimentally measured. In parallel, a mechanistic model describing aroma release while eating a liquid food was developed...

INTRODUCTION: Facial growth changes the position of the jaws (in particular vertical position of the maxilla and antero-posterior position of the mandible) and may, in turn, modify the position of the tongue and the hyoid bone, thus, generating modifications of the upper airway space. In the present paper, effects on upper airway space and tongue position of a new functional appliance, the swallowing occlusal contact intercept appliance (SOCIA) have been investigated. MATERIALS AND METHODS: Retrospective cephaolmetric study of twenty-four children (mean age 9...

REVIEW
Balaji Rangarathnam, Erin Kamarunas, Gary H McCullough
The objective of this review is to gather available evidence regarding the role of the cerebellum in swallowing-related functions. We reviewed literature on cerebellar functions related to healthy swallowing, patterns of dysphagia in individuals with cerebellar lesions, and the role of the cerebellum in therapeutic intervention of neurogenic dysphagia since 1980. A collective understanding of these studies suggests that both hemispheres of the cerebellum, predominantly the left, participate in healthy swallowing...

BACKGROUND: Breathing and swallowing are physiologically linked to ensure effortless gas exchange during oronasal breathing and to prevent aspiration during swallowing. Studies have indicated consistent aspiration in chronic obstructive pulmonary disease, mainly related to delayed swallowing reflex and problems with lingual propulsion and pharyngeal peristalsis as a result of bilateral weakness and incoordination of the related muscles. The purpose of the present study was to evaluate swallowing transit times and valleculae residue characteristics of stable COPD patients who have no swallowing complaints...
