tympanic membrane disease

Tympanic Membrane Diseases: A Comprehensive Overview

The tympanic membrane, also known as the eardrum, plays a crucial role in maintaining hearing and balance. However, various diseases can affect this delicate structure, leading to symptoms such as hearing loss, ear pain, and discharge.

• Tympanosclerosis: This condition refers to scarring of the eardrum, which can occur due to trauma or surgery (1). In severe cases, it may result in hearing loss (8).
• Tympanic Membrane Perforations (TMPs): TMPs are holes in the eardrum that can be caused by infection, trauma, or otologic procedures (4). Symptoms include ear pain, discharge, and hearing loss.
• Acute Otitis Media: This bacterial or viral infection of the middle ear often accompanies an upper respiratory infection (5). Common symptoms include ear pain, discharge, hearing loss, tinnitus, and vertigo.

Common Symptoms

The symptoms of tympanic membrane diseases can vary depending on the condition. However, some common signs include:

• Ear pain that may subside quickly
• Mucus-like, pus-filled or bloody drainage from the ear
• Hearing loss
• Ringing in the ear (tinnitus)
• Spinning sensation (vertigo)

Complications

If left untreated, tympanic membrane diseases can lead to complications such as chronic infection, hearing loss, and even meningitis.

Common Signs and Symptoms of Tympanic Membrane Disease

The tympanic membrane, also known as the eardrum, plays a crucial role in hearing by transmitting vibrations from the outer ear to the middle ear. However, when it becomes diseased or damaged, various symptoms can occur.

• Ear Pain: A common symptom of tympanic membrane disease is ear pain, which can range from mild to severe [1]. The pain may be constant or intermittent and can be exacerbated by lying down.
• Hearing Loss: Tympanic membrane disease can cause hearing loss in the affected ear, which can be temporary or permanent depending on the severity of the condition [2].
• Discharge or Drainage: In some cases, a ruptured eardrum can lead to discharge or drainage from the ear, which may be clear, pus-filled, or bloody [3].
• Ear Noise or Buzzing (Tinnitus): Some individuals with tympanic membrane disease may experience ear noise or buzzing, which can be constant or intermittent.
• Fever: In some cases, fever can accompany tympanic membrane disease, especially if the condition is caused by an infection.
• Swelling Behind the Ear: Swelling behind the ear, known as mastoiditis, can occur in some cases of tympanic membrane disease [4].

Other Possible Symptoms

In addition to these common symptoms, other possible signs and symptoms of tympanic membrane disease include:

• Trouble Sleeping: Some individuals with tympanic membrane disease may experience trouble sleeping due to ear pain or discomfort.
• Crying or Fussiness in Children: In children, tympanic membrane disease can cause crying or fussiness, especially if the child is experiencing ear pain or discomfort [5].
• Tugging or Pulling at an Ear: Some children with tympanic membrane disease may tug or pull at their ear due to discomfort or pain.

Diagnostic Tests for Tympanic Membrane Disease

The diagnosis of tympanic membrane (TM) disease involves a combination of clinical evaluation, otoscopy, and other tests to assess the condition of the middle ear. Here are some diagnostic tests used to evaluate TM disease:

• Otoscopy: A visual examination of the external auditory canal and tympanic membrane using an otoscope is essential for diagnosing TM disease. Pneumatic otoscopy can also be used to assess the mobility of the tympanic membrane.
• Tympanometry: This test measures the movement of the eardrum and middle ear's air pressure, providing useful quantitative information about the presence of fluid in the middle ear, mobility of the middle ear system, and ear canal volume [5].
• Pneumatic otoscopy: This is a simple test to assess the mobility of the tympanic membrane. It can help diagnose conditions such as acute otitis media, where the tympanic membrane may be bulging and have reduced mobility.
• Tuning fork tests (Weber and Rinne): These tests are used to evaluate hearing loss and middle ear function. They can help identify problems related to TM disease [3].
• High-resolution CT (HRCT) of the temporal bone: This imaging test is useful for diagnosing complex cases of TM disease, such as atretic external auditory canal or perforated tympanic membrane.
• Otomicroscopy: This test may be used to visualize small perforations in the tympanic membrane.

Key Findings

• A normal tympanic membrane should have a lateral process of malleus, cone of light, pars tensa, and pars flaccida visible during otoscopy [14].
• Pneumatic otoscopy has a better sensitivity than tympanometry alone for diagnosing TM disease [13].

Treatment Options for Tympanic Membrane Disease

The treatment of tympanic membrane disease depends on the underlying cause and severity of the condition. In some cases, no treatment is necessary if the perforation is minor and there is minimal hearing loss.

• No treatment: For non-swimming patients with minimal hearing loss, no treatment may be necessary.
• Topical antibiotics: Topical antibiotic ear drops may be prescribed to treat outer ear infections in adults and children.
• Oral antibiotics: High-dose amoxicillin (80 to 90 mg per kg per day in two divided doses) is the first choice for initial antibiotic therapy in children with acute otitis media (AOM).
• Intratympanic steroid therapy: This treatment modality is used to manage certain inner ear pathologies, including sudden sensorineural hearing loss, Ménière's disease, autoimmune inner ear disease, and acoustic trauma.
• Surgery: Invasive delivery methods, such as injection or incision into the middle ear or round window niche, may be necessary for drug delivery in severe cases.

Medications Used to Treat Tympanic Membrane Disease

The following medications are commonly used to treat tympanic membrane disease:

• Acetaminophen (Tylenol): Over-the-counter acetaminophen is often prescribed to relieve pain.
• Ibuprofen (Advil, Motrin IB): Oral ibuprofen may be used to reduce pain and inflammation.
• Ofloxacin otic: This medication is used to treat outer ear infections in adults and children.
• Ciprofloxacin: Topical ciprofloxacin is the only current topical treatment without risk of ototoxicity.

The differential diagnosis of tympanic membrane disease involves considering various conditions that can affect the middle ear and its associated structures. Here are some possible causes:

• Chronic otitis media: A long-standing infection of the middle ear, which can cause a perforated or retracted tympanic membrane [2].
• Tympanic membrane perforation: A hole in the eardrum, often caused by chronic otitis media, trauma, or other factors [2].
• Acute otitis media (AOM): An infection of the middle ear that can cause a bulging or red tympanic membrane, fever, and ear pain [8].
• Otitis media with effusion (OME): A condition where fluid accumulates in the middle ear, causing a retracted or opaque tympanic membrane [13].
• Middle ear tumors: Rare conditions such as glomus jugulotympanicum paraganglioma or facial nerve schwannoma can affect the middle ear and its structures [12].
• External ear diseases: Conditions like external otitis, eczema, or psoriasis can cause inflammation and discomfort in the outer ear and potentially affect the tympanic membrane [5].

It's essential to note that a proper diagnosis requires a thorough examination by an ear, nose, and throat (ENT) specialist, including inspection of the tympanic membrane and other middle ear structures.
