title: [Pendulation of choanal polyp detected by tomography (author's transl)].
abstract: Three cases of antro-choanal polyps are discussed. It was possible to detect pendulation of the parts of the polyps situated in the epipharynx by comparison of AP x-ray films with lateral tomographic series exposed with the patient in lateral recumbent position. Computerized tomography could be used for examination and detection of pendulation in a similar way. As pendulation is possible only in stalked epipharyngeal processes it seems reasonable to use this phenomenon as a diagnostic sign of choanal polyps.
