Keratin is a fibrous protein which gives strength and rigidity to skin and nails. Highly keratinized skin provides the basis for callus formation, as seen on the fingers of guitar players.

Callused skin has a high rate of turnover as it is constantly shed. The skin lining epithelium of the ear canal is programmed to migrate radially from the centre of the eardrum and then laterally along the ear canal walls. As this migrating skin reaches the outer half of the ear canal, it mixes with oils and perspiration from the glands in the lateral aspect of the ear canal to form ear wax.

Essentially ear wax is a mixture of dead skin cells infused with perspiration and oils. As this blend ages, it de-hyrdates and oxidizes, thereby taking on a darkened appearance. In cases of keratosis obturans, an error develops in the skin migration process. The shedding skin cells do not migrate laterally, but pile up in the inner half of the ear canal, eventually forming a semi-hard plug. Multiple layers of dead skin cells encroach over the canal in concentric fashion like onion skin.

The obstruction from keratosis obturans is different from ear wax, in that it forms in the inner half of the ear canal, as opposed to the outer half and does not contain the perspiration and oils that wax does. Consequently a keratinized plug is generally harder in texture and lighter in colour than typical ear wax.

If left untreated, the obstruction can become densely packed and the resultant pressure can erode the bone of the ear canal. While not an infective process in itself, keratosis obturans can lead to infection, particularly in the ears of patients with compromised immune-systems, such as those with diabetes or HIV.

If not controlled, infection from keratosis obturans can spread to structures outside the ear canal, including the jaw, teeth and base of the skull, and may culminate in a septic response. Treatment involves mechanical removal of the obstruction, often with the aid of an operating microscope. Care must be taken when removing a keratinized plug, as there may be bony destruction underlying the compacted skin, with possible exposure of the facial nerve. Once the ear canal is cleared, regular removal of accumulating skin cells is usually required to limit recurrence.

Ongoing mechanical clearing of the ear often leads to an eventual resolution of the condition. It is not clear what instigates keratosis obturans, but it affects both ears and is more commonly seen in individuals under the age of Some speculate that keratosis obturans may be a symptom of a systemic condition, involving chronic sinusitis and bronchiectasis.

Keratosis Obturans

Keratosis obliturans rare. Usually by chance discovered by inspectors in otoskopi examination. Keratosis obliterans usually found on a bilateral basis and may be accompanied by bronchiectasis and chronic sinusitis. In keratosis obturans found clumps of the epidermis in the ear canal caused by excessive formation of epithelial cells that do not migrate toward the outer ear. Although it can be observed widening of the ear canal and hyperplasia and epithelial and subepithelial inflammation, but no bone erosion. This condition is thought to be caused by the production of stoppers squamous epithelium and excessive or incorrect epithelial migration. The recommended treatment is removal of the plug and the handling of inflammatory processes.
