Abstract: This invention relates to an impression-taking pad (10) for taking an impression (20) of an ear canal (30) by an impression-taking material, having a lateral end (el) to be arranged away from a tympanic membrane (35) in said ear canal (30); and a medial end (em) to be arranged proximate to said tympanic membrane (35). The impression-taking pad (10) comprises an outer body (2) tapering from said lateral end (el) to said medial end (em). The impression-taking pad (10) further comprises an inner body (3) for releasable engagement with a tool (11, 12) for visual inspection of the ear canal (30), the inner body (3) being configured to support insertion of the impression-taking pad (10) in the ear canal (30) by the tool (11, 12). The impression-taking pad (10) comprises a duct (5) at least partially defmed by the inner body (3), forming at least part of an optical path for visual inspection of the ear canal (30); wherein the optical path further comprises an inspection window (6), closing said duct (5), configured to support inspection of the ear canal (30) during the insertion of the impression-taking pad (10) in the ear canal (30); The impression-taking pad (10) is further configured to form an integral part of said impression (20). The present invention also relates to a method of taking an impression by the above defmed impression-taking pad (10); as well as to a correlated impression-taking system comprising an aptly modified tool (11, 12) to cooperate with such an impression-taking pad (10).
