- Abstract:
- OBJECTIVE. This study was performed to evaluate the frequency of postdeglutitive aspiration in lateral hypopharyngeal pouches and to correlate postdeglutitive aspiration to pouch size and dynamics. MATERIALS AND METHODS. Two radiologists retrospectively analyzed 325 videofluorography examinations of patients swallowing. The 325 patients were 22-81 years old, 173 men and 152 women. Patients who had undergone surgery of the hypopharynx were excluded from the study. All pouches found on videofluorography were classified into grade I, II, or III. Because iodinated contrast agent had been used initially, patients who had no or minimal aspiration underwent a second imaging examination using high-density barium. RESULTS. Of the 325 patients, 118 had lateral hypopharyngeal pouches: 77 bilateral and 41 unilateral. Postdeglutitive aspiration was diagnosed in 14 (56%) of the 25 grade III pouches and in two (3%) of the 58 grade II pouches. Aspiration was not seen in any of the 112 grade I pouches. CONCLUSION. The prevalence of postdeglutitive aspiration is high in patients who have grade III pouches. To date, no appropriate conservative treatment has been described; however, in severe cases surgery is warranted.
