Abstrakt: The mucociliary clearance (MCC) is an important defence mechanism of the middle ear. The mucociliary transport (MCT) is a part of MCC. We measured the duration of MCT and visualised its routes in middle ears of 31 patients (mean age 45 years; range 7-61 years; SD 11.6) with intact tympanic membrane, with ventilated middle ears and without a history of prolonged otitis media. The transition time of indigo carmine dye from the promontory mucosa to the middle ear orifice of the Eustachian tube (ET) was observed with a rigid 30°, 1.7-mm-diameter tympanoscope. The dye took an average of 7 min (range 4.5-15 min; SD 3.4; median 4.5) to reach the ET orifice in 25 (81 %) patients. Three main ciliary pathways were detected: (1) below and parallel to the tensor tympani muscle; (2) downwards, anterior to the round window, and then ascending to the ET; and (3) straight across the promontory.
