Otosclerosis is a condition of the middle ear where portions of the dense enchondral layer of the bony labyrinth remodel into one or more lesions of irregularly-laid spongy bone. As the lesions reach the stapes the bone is resorbed , then hardened ( sclerotized ), which limits its movement and results in hearing loss , tinnitus , vertigo or a ...
The ossicular chain is a crucial structure in the middle ear, responsible for transmitting sound vibrations from the tympanic membrane to the inner ear. This chain consists of three tiny bones: the malleus, incus, and stapes. They are connected by ligaments and joints that allow for the efficient conduction of sound waves. [1] The ossicular ...
Otosclerosis is a congenital or spontaneous-onset disease characterized by abnormal bone remodeling in the inner ear. Often this causes the stapes to adhere to the oval window, which impedes its ability to conduct sound, and is a cause of conductive hearing loss. Clinical otosclerosis is found in about 1% of people, although it is more common ...
When a stapedectomy is done in a middle ear with a congenitally fixed footplate, the results may be excellent but the risk of hearing damage is greater than when the stapes bone is removed and replaced (for otosclerosis). This is primarily due to the risk of additional anomalies being present in the congenitally abnormal ear.
Schwartz sign, also known as Flemingo's pink sign, is a diagnostic indicator for otosclerosis, a disease of the bones of the middle or inner ear. In clinical examination of the ear drum, increased vascularity of the promontory may be seen through the ear drum. This sign is known as Flemingo's flush sign or Schwartz's sign.
The ossicles (also called auditory ossicles) are three irregular bones in the middle ear of humans and other mammals, and are among the smallest bones in the human body. . Although the term "ossicle" literally means "tiny bone" (from Latin ossiculum) and may refer to any small bone throughout the body, it typically refers specifically to the malleus, incus and stapes ("hammer, anvil, and ...
A healthy middle ear is filled with air, not fluid. Having fluid in there can be uncomfortable, serve as a breeding ground for infection, and not to mention cause a lot of pressure and pain in the ...
The annular stapedial ligament (also called the stapediovestibular joint) is a ring of fibrous soft tissue that connects the base of the stapes to the oval window of the inner ear. Calcification and hardening of the annular ligament of the stapes ( otosclerosis ) is a common cause of adult deafness .
