Dysphagia, with its inherent risk of aspiration, is a clinical problem frequently encountered in patients with brain injury from trauma or cerebrovascular accident. The use of nasogastric tubes and intravenous lines for nutrition and hydration can be cumbersome and uncomfortable for the patient, and can interfere with rehabilitation therapy. With the advent and increased use of video- and cinefluoroscopy to evaluate swallowing, the type of dysphagia can be defined more readily. This article describes the use of a heparin lock at night to provide fluids intravenously to a patient who could swallow solid or semisolid food, but aspirated thin liquids. This approach insured adequate hydration while keeping the patient free of parenteral lines and nasogastric tubes during therapy. This technique was continued for 3 1/2 weeks until the patient's dysphagia improved and a full oral diet could be resumed. The authors recommend the use of nighttime intravenous feeding via a heparin lock as an option for managing this subset of dysphagic patients in a rehabilitation setting.

Symptoms compatible with vertebrobasilar ischemia have been reported in patients with unilateral or bilateral carotid occlusive disease. Intracranial steal phenomena have been proposed to explain the symptoms. In a review of 54 patients with angiographically documented severe bilateral carotid stenosis (less than or equal to 2 mm residual lumen) or occlusion, eight had symptoms suggesting vertebrobasilar insufficiency. Five patients were identified retrospectively, and the other three were evaluated prospectively. Symptoms included various combinations of hemodynamically mediated, transient bilateral motor, sensory, or visual impairment. Dysarthria, dysphagia, and diplopia were generally absent. Each patient also described additional symptoms compatible with transient hemispheric or retinal ischemia. The anatomic regions subserving the bilateral vertebrobasilar-like symptoms could be correlated with angiographically estimated arterial border zones in both hemispheres and may thus represent bilateral hemispheric border zone ischemia rather than brain stem ischemia. An intracranial steal need not be invoked.

Dysphagia can be caused by a host of factors, most of which are structural or functional. However, despite extensive evaluations, a certain number of patients have unexplained dysphagia. We present an extremely unusual case whereby a patient with an acute left hemispheric cerebral vascular accident presents with dysphagia as his sole complaint and after extensive neurological, gastroenterological, and radiographic examinations is found to have cricopharyngeal dysfunction. The etiology of this defect was not at all clinically apparent and, ultimately, magnetic resonance imaging (MRI) was performed which revealed a chronic infarction of the right frontal lobe and a smaller acute infarction in the same location of the left. This case demonstrates that swallowing disorders may be the sole presentation of stroke and that, if extensive evaluations of such patients fail to yield an etiology, one must strongly consider MRI as a tool for diagnosis, even if a CT scan is negative.

Dysphagia is a disorder of the swallowing mechanism and presents a major problem in the rehabilitation of stroke patients and head injured patients. The authors have identified several biomechanical parameters that characterize the oral musculature and have developed techniques to quantify these parameters in normal and dysphagic patients. These parameters include lip closure pressure, lip interface shear force, tongue thrust, and swallow pressure. Significant differences were found in each of these parameters measured in normal and dysphagic patients. The quantitative measurements may aid the physician in choosing the appropriate therapy during the course of recovery.

Acute mutism with paralysis of the bulbar and facial muscles following discrete bilateral internal capsular infarction is a rare stroke syndrome. We describe a 62 year-old male who suddenly became unable to speak or swallow. The paucity of facial expression and inability to voluntarily move the facial, lingual and pharyngeal muscles were persistent and contrasted with a relatively mild limb paresis which recovered. High resolution CT scan revealed infarcts in the posterior limbs of both internal capsules. It is important to recognise this stroke syndrome because of the permanence of dysarthria and dysphagia associated with it.

Data from 357 conscious stroke patients taking part in an acute intervention trial and assessed within 48 hours of the onset of symptoms, were used to investigate the prevalence and natural history of swallowing problems. Nearly 30% of patients with single-hemisphere strokes were initially found to have difficulty swallowing a mouthful of water, but in most of those who survived, the deficit had resolved by the end of the first week. Strong correlations were found between dysphagia and speech impairment (comprehension and expression) and with facial weakness, but there was no association with the side of the stroke. After controlling for other markers of overall stroke severity such as conscious level, urinary continence, white blood cell count and strength in the affected limbs, swallowing impairment still showed a significant inverse correlation with functional ability at 1 and 6 months. These results indicate that, even if dysphagia itself is not responsible for much excess mortality in acute stroke, it might still lead to complications which hamper functional recovery.

Neurologic deficiencies, with special reference to pharyngeal function, were studied prospectively in 12 patients before and after they underwent carotid endarterectomy. Pharyngeal function was monitored with cineradiography. Five patients developed pharyngeal dysfunction: defective closure of the laryngeal vestibule, epiglottic dysmotility, and pharyngeal constrictor paresis 1 week postoperatively. In 2 patients this dysfunction remained, while in 3 it had resolved 4 weeks after the operation. Pharyngeal dysfunction was more common in patients with preoperative minor stroke and a temporary perioperative carotid shunt and in patients with a long operation time. The registered transient pharyngeal dysfunction may be due to manipulation of the cervical structures including the vagus nerve and the pharynx or due to cerebrovascular damage during the operation. Our findings support careful monitoring of postoperative oral finding in patients at risk.

Dysphagia is a well-recognized complication of stroke. We report two cases of dysphagia in stroke patients caused by the pharyngeal impaction of dental prostheses. Radiologic identification of such impaction is unreliable due to the increasing use of radiolucent material in dental prostheses. We recommend direct or indirect laryngoscopy to exclude foreign body impaction in all patients complaining of dysphagia.

The co-ordination of respiration and swallowing was recorded electronically in three groups of patients who complained of dysphagia following a stroke, or associated with multiple sclerosis or motor neurone disease. The test used was simple and the equipment easily taken to the patient, in bed if necessary. All the patients showed differences from normal subjects and there were differences between each of the neurologically impaired groups. The technique appears to allow an assessment of the state of oropharyngeal motor and sensory functions separately during swallowing.

Experience from the use of feeding plates for babies with cleft palate and from the treatment of dysphagia in patients recovering from stroke led to the design of a simple intraoral appliance. This device has been used successfully in treating twelve babies with feeding difficulties caused by incoordination, when other methods had failed.
