Round Window Fibrous Plugs [PDF]
Otology & Neurotology, 2010 Intratympanic drug delivery is now widely used in the clinical setting. A variety of medications and substances have been shown to pass from the middle to the inner ear via the round window membrane (RWM) (1). The surface area of the round window is approximately 2.5 mm2. The RWM is thicker around the edges and thinner in the center, with an average

Round window membrane rupture [PDF]
The Laryngoscope, 1978 AbstractRound Window Membrane Rupture is a surgically correctable cause of sudden hearing loss and vertigo. Reported is a 19‐year‐old male who had proven round window membrane rupture secondary to barotrauma. Surgical exploration revealed an abnormally large round window niche and membrane, possibly predisposing him to this injury.
