Much of the initial research on normal swallowing has been conducted in young men. Recently, there has been increasing interest in determining whether there are differences between the sexes in swallowing function and in the effects of aging on swallowing in both sexes. This investigation examined the swallowing ability of 8 healthy young women between the ages of 21 and 29 and 8 healthy older ...

UNLABELLED Dysphagia can be a consequence of total laryngectomy even in the absence of symptoms and it could indeed directly or indirectly compromise quality of life. AIM To evaluate the characteristics of swallowing after total laryngectomy and pharyngolaryngectomy with pharyngeal T closure, correlating them with the Quality of Life in Swallowing Disorders questionnaire. METHODS A prospect...

Dysphagia is common in patients with neurological disorders. It may result from lesions in the central or peripheral nervous system as well as from diseases of muscle and disorders of the neuromuscular junction. Drugs that are commonly used in the management of neurological conditions may also precipitate or aggravate swallowing diYculties in some patients. Neurogenic dysphagia often results in...

Swallowing disorders are common in the elderly, and aging is a factor that affects swallowing function. The elevation of the hyoid bone is important for swallowing and is controlled by the suprahyoid muscles. The hyoid and laryngeal elevation allows the bolus to enter the esophagus. The suprahyoid muscles, therefore, play an important role in swallowing. The effects of aging on suprahyoid muscl...

In this study we suggest that the velocity of water entering the cervical esophagus can be used as an index of pharyngeal swallowing function. In this article, the basic in vitro principles of water and viscous water flow velocity evaluation using ultrasonic methods are introduced. Water flow involving small gas bubbles passing through a silicon tube could be monitored in the B-mode images and ...
