Silent aspiration is important phenomenon in management of patients with swallowing difficulties. Normal subjects cough out inhaled material to avoid deep aspiration. But some dysphagic patients do not cough when aspiration occurs.
We carried out the videofluorography (VF) on 280 patients who were suspected of having swallowing problems to confirm whether they had silent aspirations. Aspirators, as a result of the VF, were 143 of the patients (51.1%). Among them silent aspirations were seen in 38 patients (26.6%). Silent aspirations were seen more frequently in stroke patients, and also in patients with the aspiration type of "before the swallow".

Object: We investigated the relationship between the videofluorographic (VF) findings in swallowing and pneumonia in elderly.
Subjects and Design: The subjects were elderly patients who were admitted to our university hospital with pneumonia and referred to our rehabilitation medicine department for conforming swallowing problems. Patients were examined by our routine VF, whose findings were classified in several categories.
Results: Many of them had delayed swallowing reflex and some patients exhibited impaired oral propulsion in VF, but obvious aspirations were rare.
Conclusion: Although impaired swallowing seemed to have the relations with the occurrence of pneumonia in elderly, sufficient evidence of aspiration were not confirmed in VF of many of the patients. Other possibilities of aspiration, such as nocturnal gastroesophageal reflux, must be investigated.
