Surfer's ear is the common name for an exostosis or abnormal bone growth within the ear canal. They are otherwise benign hyperplasias (growths) of the tympanic bone thought to be caused by frequent cold-water exposure. [1] Cases are often asymptomatic. [1] Surfer's ear is not the same as swimmer's ear, although infection can result as a side ...
The bony portion of the ear canal is nearly 2 cm long and is directed inward and slightly forward: at the same time it forms a slight curve, so that the floor of the canal is convex upward. In sagittal section it presents an oval or elliptical shape with the long axis directed downward and slightly backward.
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 bony part forms the inner two thirds. The bony part is much shorter in children and is only a ring (annulus tympanicus) in the newborn. The layer of epithelium encompassing the bony portion of the ear canal is much thinner and therefore, more sensitive in comparison to the cartilaginous portion. Size and shape of the canal vary among ...
Exostoses can cause chronic pain ranging from mild to debilitatingly severe, depending on the shape, size, and location of the lesion. It is most commonly found in places like the ribs, where small bone growths form, but sometimes larger growths can grow on places like the ankles, knees, shoulders, elbows and hips. Very rarely are they on the ...
Reconstruction of the ear canal wall. Canal wall reconstruction has been performed using ear canal skin alone, fascia, cartilage and titanium as well as by replacing the original intact wall. If the reconstruction is poorly performed, it may result in a high rate of recurrent cholesteatoma. [20] Preservation of the ear canal wall.
A glomus jugulare tumor is a tumor of the part of the temporal bone in the skull that involves the middle and inner ear structures. This tumor can affect the ear, upper neck, base of the skull, and the surrounding blood vessels and nerves. A glomus jugulare tumor grows in the temporal bone of the skull, in an area called the jugular foramen.
Canaloplasty, where the ear canal is widened using grafts, was first proposed as the treatment for keratois obturans. However, with the migration of keratin within the canal, any amount of widening could not restore the migration of skin. Reconstruction of the bony canal with cartilage graft from temporalis fascia has showed some results. [6]
