obsolete Tympanosclerosis of tympanic membrane and ossicles

What is Tympanosclerosis?

Tympanosclerosis is a condition characterized by the deposition of calcium in the middle ear, leading to scarring and hardening of the eardrum (tympanic membrane) and/or the ossicles. This can result in conductive hearing loss due to fixation of the ossicular chain.

Causes and Effects

The condition is often associated with recurrent or chronic middle ear inflammation, which leads to fibrosis and calcification of the affected tissues. Tympanosclerosis can affect any part of the tympanic cleft, including the submucosal areas, ossicles, ligaments, joints, and muscle tendons.

• Tympanic membrane involvement: In 50% of cases, tympanosclerosis affects only the tympanic membrane, resulting in a white plaque-like lesion.
• Intratympanic structures involvement: In 30% of cases, the condition involves the intratympanic structures, including the ossicles, ligaments, joints, and muscle tendons, leading to varying degrees of fixity of the ossicular chain.

Symptoms and Diagnosis

Tympanosclerosis can cause conductive hearing loss due to fixation of the ossicular chain. The symptoms may include:

• Hearing loss
• Tinnitus (ringing in the ears)
• Ear fullness or pressure

The condition is typically diagnosed through a combination of clinical examination, otoscopy, and imaging studies such as CT scans.

Treatment and Management

There is no specific treatment for tympanosclerosis. However, management strategies may include:

• Conservative management: In cases where the condition is asymptomatic or mildly symptomatic, conservative management with observation and monitoring may be recommended.
• Surgical intervention: In more severe cases, surgical intervention may be necessary to relieve symptoms and improve hearing.

2. [10] defines Tympanosclerosis as "scarring of your eardrum (tympanic membrane)" and explains how calcium deposits can cause the eardrum to harden, thicken, and become rigid.
3. [11] notes that unless the tympanic membrane involvement is severe, it is rare for Tympanosclerosis to cause an appreciable conductive hearing loss.

Common Signs and Symptoms of Obsolete Tympanosclerosis

Obsolete Tympanosclerosis, a condition characterized by scarring on the eardrum (tympanic membrane) and calcification of tissue in the middle ear, including the ossicles, can manifest in various ways. The symptoms may vary depending on the extent and location of the calcified plaques.

• Hearing Loss: Hearing loss is the most prevalent symptom, ranging from mild to severe [11]. The calcification can affect the mobility of the tympanic membrane and ossicles, leading to impaired sound conduction.
• Ear Pain: Some individuals may experience ear pain or discomfort due to the scarring on the eardrum [1].
• Vertigo: Vertigo, a sensation of spinning or dizziness, may occur in some cases [4].
• Fever and Lethargy: In rare instances, fever and lethargy can be symptoms of Tympanosclerosis, although these are nonspecific signs that can be associated with various conditions [1], [4].

Other Possible Symptoms

In addition to the above-mentioned symptoms, some individuals may experience:

• Ear Drainage: In cases where the scarring leads to a perforation in the eardrum, ear drainage or otorrhoea may occur [5].
• Irritability and Discomfort: Some people may feel irritable or uncomfortable due to the presence of calcified plaques on the eardrum.

Important Note

It is essential to note that not everyone with Tympanosclerosis will experience symptoms. In many cases, the condition may be asymptomatic, and treatment may only be necessary if hearing loss or other complications arise [12].

Diagnostic Tests for Obsolete Tympanosclerosis

Tympanosclerosis, a condition characterized by scarring of the eardrum (tympanic membrane) and/or ossicles, can be diagnosed using various tests. Here are some diagnostic tests that may be used to identify obsolete tympanosclerosis:

• Otoscopic examination: This is a non-invasive test where an otoscope is used to examine the external auditory canal, tympanic membrane, and middle ear. The exam may reveal signs of scarring or calcification on the tympanic membrane (TM) [12].
• Tympanometry: This test uses an electroacoustic impedance bridge to record compliance of the TM and middle ear pressure. Tympanosclerosis can affect the mobility of the TM, which may be detected by tympanometry [7].
• Computed Tomography (CT) scan: A CT scan of the temporal bone can help confirm the presence of a tympanosclerotic focus and exclude other conditions [3]. However, this test is not typically used for diagnosing obsolete tympanosclerosis.
• Audiometry: Audiometric tests, such as pure-tone audiometry or speech audiometry, may be used to assess hearing loss associated with tympanosclerosis. While these tests are not specific for tympanosclerosis, they can help identify conductive hearing loss [5].
• Otoacoustic emissions (OAEs) and Auditory Brainstem Response (ABR): These tests can also be used to assess hearing function in individuals with suspected tympanosclerosis. However, they are not specific for this condition.

Other Diagnostic Tests

In addition to the above-mentioned tests, other diagnostic methods may be used to identify obsolete tympanosclerosis, including:

• Histopathological examination: This test involves examining tissue samples from the affected area under a microscope.
• Imaging studies: Other imaging studies, such as magnetic resonance imaging (MRI), may also be used to diagnose and monitor the progression of tympanosclerosis.

[3] Computed tomography (CT) or nowadays preferably cone beam CT scan of the temporal bone might help to confirm an otosclerotic focus. It may also help to exclude other conditions. [5] Although evaluation can be complemented by other tests, such as otoacoustic emissions and Auditory Brainstem Response (ABR), audiometry is mainly used for assessing hearing function in individuals with suspected tympanosclerosis. [7] Tympanometry uses an electroacoustic impedance bridge to record compliance of the tympanic membrane and middle ear pressure. Tympanosclerosis can affect the mobility of the TM, which may be detected by tympanometry. [12] Clinicians perform an otoscope exam to assess the condition of the external auditory canal (EAC), tympanic membrane (TM), and the middle ear. Steps of the otoscope exam include inspecting the EAC and the TM with its identifying landmarks as outlined below.

Treatment Options for Obsolete Tympanosclerosis

Tympanosclerosis, a condition characterized by calcareous plaque deposition in the middle ear cavity and ossicles, can be challenging to treat. While surgical removal of sclerotic foci and reconstruction of auditory ossicular chain are primary treatment options, medical treatment may also be considered for obsolete cases.

Medical Treatment

According to search results [10][11], medical treatment primarily involves the use of antibiotics and decongestants/antihistamines together with analgesia. However, this approach is more relevant to otitis media rather than tympanosclerosis specifically.

For obsolete tympanosclerosis, a study by P Morris in 2012 [1] suggests that topical antibiotics may improve symptoms compared to placebo or either treatment alone. Another study by JC Luers in 2016 [2] discusses the surgical anatomy of the human middle ear and its adjacent areas, but does not provide specific information on medical treatment for tympanosclerosis.

Antibiotic Treatment

Amoxicillin (20-40 mg/kg) or sulfisoxazole (50 mg/kg) may be administered once daily as chemoprophylaxis to suppress symptoms of otitis media [5]. However, the effectiveness of this approach in treating obsolete tympanosclerosis is unclear.

Nonsteroidal Anti-Inflammatory Drugs

Nonsteroidal anti-inflammatory drugs (NSAIDs), such as those mentioned in search result [9], may be considered for pain management and inflammation reduction. However, their role in treating obsolete tympanosclerosis specifically is not well established.

In summary, while medical treatment options exist for obsolete tympanosclerosis, the effectiveness of these approaches is limited, and surgical removal of sclerotic foci remains a primary treatment option. Further research is needed to determine the optimal treatment strategy for this condition.

Differential Diagnosis of Obsolete Tympanosclerosis

Tympanosclerosis, a condition characterized by the deposition of hyaline material around the tympanic membrane and hypertrophic submucosa in the middle ear cavity due to inflammation [15], can be challenging to diagnose. When considering differential diagnosis for obsolete tympanosclerosis affecting the tympanic membrane and ossicles, several conditions come into play.

Conditions Affecting Middle Ear Sound Conduction

• Otosclerosis: This is a condition where abnormal bone growth in the middle ear causes hearing loss [5]. It can mimic the symptoms of tympanosclerosis.
• Cholesteatoma: A type of skin cyst that grows in the middle ear, causing conductive hearing loss and potentially leading to more serious complications if left untreated [11].
• Tympanic membrane perforation: This is a condition where there is a hole or tear in the tympanic membrane, which can lead to chronic otitis media and potentially result in tympanosclerosis [1].

Other Middle Ear Pathologies

• Superior canal dehiscence syndrome (SCDS): A rare condition that affects the superior semicircular canal, leading to conductive hearing loss and vertigo [5].
• Middle ear masses: These can be benign or malignant growths in the middle ear, which can cause conductive hearing loss and other symptoms [12].

Clinical Considerations

When diagnosing obsolete tympanosclerosis, it's essential to consider these differential diagnoses. A thorough examination of the patient, including a review of their medical history and physical examination findings, is crucial for accurate diagnosis.
