Tympanic Thickening

Tympanic thickenings are a cluster of sections (edges of bones) of the air-bearing bone canal (tympanic cavity) of different sizes and shapes, located inside the external auditory canal. These are individual modifications of the walls, parts of the air-bearing bones, and the walls of the narrowing of the canal of the membranous tympanic septum.

Tympanic cyst. As a result of the injury, a tympanic cyst of 27/3 cm was formed. The structure of its wall contains amorphous osteoid tissue, calcareous bone transformations, loose fat, and also lymphoid cells in small quantities. The bottom of the tympanic cyst formed a labyrinth of channels pierced by cystic canals. Cystic canals contain and connect various ciliary and lymphoepithelial patterns of the inner surface. The inner surface of the cyst wall reflects a capillary network saturated with mucin (a substance produced by the cardiac glands). The wall has a leafy, oval shape, and therefore does not form gaps, making breathing and hearing difficult
