Granular myringitis

Granular myringitis is a chronic inflammation of the ear drum (tympanic membrane) characterized by the presence of granulation tissue. This condition is also known as chronic granular otitis externa.

Causes

The exact cause of granular myringitis is unknown. However, it is often associated with chronic otitis media and otitis externa, which are infections of the middle and outer ear, respectively. Other potential causes include trauma to the ear, allergic reactions, and certain systemic diseases such as diabetes and immunodeficiency.

Symptoms

The main symptom of granular myringitis is persistent ear discharge, which can be clear, yellow, or bloody. Other symptoms may include ear pain, hearing loss, and tinnitus (ringing in the ears). In severe cases, the condition can lead to complications such as cholesteatoma (a skin cyst in the middle ear) and mastoiditis (infection of the mastoid bone behind the ear).

Diagnosis

Diagnosis of granular myringitis is based on the clinical symptoms and examination of the ear. The doctor may use an otoscope to look at the ear drum and see the granulation tissue. In some cases, a sample of the discharge may be taken for laboratory testing to identify any infectious agents.

Treatment

Treatment of granular myringitis usually involves a combination of medical and surgical therapies. Medical treatment includes the use of topical antibiotics and steroids to reduce inflammation and treat any underlying infection. Surgical treatment may involve removal of the granulation tissue and repair of the ear drum. In severe cases, a tympanoplasty (surgery to reconstruct the ear drum) may be necessary.

Prognosis

The prognosis for granular myringitis is generally good with appropriate treatment. However, the condition can be recurrent and may require long-term management.
