The "tympanic wink" illustrates a beating brillance born on the antero-inferior quadrant of the promontory and appearing on the tympanic membrane as a false beating light triangle. This sign may be an aid in discovering a minor vascular abnormality of the middle ear: hypertrophy of carotico-tympanic or inferior tympanic arteries, dehiscence of the ascending part of the internal carotid canal or the possibility of a persistent stapedial artery.
“鼓膜眨眼征”表现为在岬前下象限出现的搏动性亮点，并在鼓膜上呈现为假性搏动性光三角。该体征可能有助于发现中耳的轻微血管异常：颈鼓动脉或鼓室下动脉肥大、颈内动脉管升部裂开或存在镫骨动脉持续存在的可能性。
