Dysphagia is difficulty of effect movement of the bolus from the mouth to the stomach. From and anatomical standpoints, dysphagia is typically classified as oropharyngeal dysphagia (OPD) and esophageal dysphagia (ED). In general, OPD is more highly prevalent condition compared with ED, and associated with severe complications such as malnutrition, dehydration and aspiration pneumonia. These complications are fatal especially in the elderly. Therefore, for preventing severe complications, appropriate and prompt management should be provided to dysphagia patients. However, the decrease of swallowing function is considered as a part of natural aging process. This condition is called as presbyphagia. Although Presbyphagia refers to characteristic changes in the process of swallowing of healthy elderly, it can be a risk factor of dysphagia. With this in mind, for avoiding overdiagnosis or underdiagnosis of dysphagia, we should distinguish among presbyphagia, dysphagia and other related diagnoses. For this reason, understanding about physiology of normal swallowing and natural changes of swallows by aging are essential for physicians. Hence, this review discusses the normal swallow, senile changes of swallow, and dysphagia especially in OPD.
