Obsolete Adhesions of Drum Head to Promontorium

The obsolete adhesions of drum head to promontorium refer to a medical condition where there is an abnormal attachment or adhesion between the tympanic membrane (drum head) and the promontory, a bony structure in the middle ear.

Characteristics:

• The adhesions are considered obsolete, meaning they are no longer used as a valid medical term.
• They involve an abnormal connection between the tympanic membrane and the promontory.
• This condition is part of a broader category of adhesive middle ear diseases.

ICD-9 Code: The ICD-9 code for this condition is 385.13, which was used to indicate a diagnosis on a reimbursement claim until September 30, 2015.

Related Conditions:

• Adhesions of drum head to incus (ICD-9 code 385.11)
• Adhesions of drum head to stapes (ICD-9 code 385.12)

These conditions all relate to abnormal attachments or adhesions between the tympanic membrane and different structures in the middle ear.

• International Classification of Diseases 9th Revision: 38513 [6]
• Adhesive middle ear disease with adhesions of drum head to promontorium (disorder) [10, 11]

Based on the provided context, it appears that there are some common issues related to drum heads and ear-related problems. However, I'll focus on addressing your query regarding signs and symptoms of obsolete adhesions of a drum head to the promontorium.

Signs and Symptoms:

• Adhesion between the mucosal surface of the eardrum and the promontorium is a common problem in middle ear surgery [2].
• This condition can lead to various issues, including:
  • Dull sound or tone from the drum head [13][15]
  • Drum head stretching over time due to constant pressure [15]
  • Needing to replace drum heads more frequently, especially on the bass and snare drums [15]

Prevention and Maintenance:

• Regularly inspect your drum heads for signs of wear, such as dents, scratches, or stretched areas [13].
• Proper maintenance is crucial for extending the lifespan of drum heads. This includes:
  • Using a hair dryer or heat gun to remove dents or minimize them on the drum head [10]
  • Choosing the right drum heads for your sound and understanding factors that affect longevity [11]

Pre-muffling Techniques:

• Adding a layer of Mylar or other material to the top or underside of the outer edge can help pre-muffle the drum head [14].
• Evans' 2-ply, oil-filled Hydraulic head is another method used for pre-muffling, which produces a specific sound [14].

Please note that these points are related to drum heads and not directly to ear-related problems. However, I've tried to provide relevant information based on the context provided.

[15] - Since constant pressure is applied, drum heads increasingly stretch over time, eventually resulting in a dull sound [15].

Obsolete Diagnostic Tests for Adhesions of Drum Head to Promontorium

Adhesions of the drum head to promontorium, also known as adhesive otitis media, is a condition where the tympanic membrane (eardrum) becomes adherent to the promontory, a bony structure in the middle ear. While there are still some diagnostic tests used today, several older tests have been deemed obsolete due to advancements in medical technology and understanding of the condition.

Obsolete Tests:

• Audiometric studies [1] - These tests were once considered diagnostic procedures for adhesions of the drum head to promontorium, but they are no longer recommended.
• ICD-9 385.11 Adhesions of drum [14] - This code was used to indicate a diagnosis on a reimbursement claim, but it is only applicable for claims with a date of service on or before September 30, 2015.

Current Diagnostic Approaches:

While the above tests are considered obsolete, modern diagnostic approaches focus on more accurate and reliable methods. These include:

• Clinical evaluation and history taking
• Otoscopy to visualize the tympanic membrane and middle ear structures
• Imaging studies such as CT or MRI scans to assess the extent of adhesions and any associated complications

[1] Context result 1 - Audiometric studies are diagnostic tests that were once considered obsolete for adhesions of the drum head to promontorium. [14] Context result 14 - ICD-9-CM 385.13 is a billable medical code for adhesions of drum head to promontorium, but it has limited applicability.

Based on the provided context, it appears that there are limited treatment options for adhesive otitis media (AOM) where the tympanic membrane is adhered to the promontory.

According to search result [3], drug therapy is not curative in many cases of AdOM. This suggests that medical treatments may not be effective in resolving adhesions between the tympanic membrane and the promontory.

However, there are some alternative approaches mentioned in the context:

• Tympanoplasty with cell sheet transplantation (search result [2]) can be used to treat adhesive otitis media by preventing mucosal adhesions.
• The use of Silastic disk (search result [10]) seems to avoid a new adhesion of the tympanic membrane to the promontory.

It's worth noting that these approaches may not directly address the issue of obsolete adhesions between the drum head and the promontorium. However, they may provide some insight into potential treatment options for this condition.

Here are some possible treatment options:

• Tympanoplasty with cell sheet transplantation: This surgical procedure can be used to treat adhesive otitis media by preventing mucosal adhesions.
• Use of Silastic disk: The proposed addition of a Silastic disk seems to avoid a new adhesion of the tympanic membrane to the promontory.

Please note that these options may not directly address the issue of obsolete adhesions between the drum head and the promontorium. Further research or consultation with an expert would be necessary to determine the most effective treatment approach.

Differential Diagnosis of Adhesions of Drum Head to Promontorium

Adhesions of the drum head to promontorium, also known as adhesions of the tympanic membrane to the promontory, are a type of middle ear pathology. The differential diagnosis for this condition involves considering various other possible causes of similar symptoms.

Possible Causes:

• Otitis media: Inflammation of the middle ear, which can cause adhesions between the drum head and the promontorium.
• Chronic otitis media with effusion (COME): A condition characterized by fluid accumulation in the middle ear, leading to adhesions and other complications.
• Tympanosclerosis: A type of scarring in the tympanic membrane that can cause adhesions to form between the drum head and the promontorium.
• Middle ear tumors: Rarely, tumors in the middle ear can cause adhesions between the drum head and the promontorium.

Clinical Features:

The clinical features of adhesions of the drum head to promontorium may include:

• Conductive hearing loss
• Tympanic membrane retraction or adhesion
• Middle ear effusion or fluid accumulation
• Otorrhea (discharge from the ear)

Diagnostic Workup:

The diagnostic workup for adhesions of the drum head to promontorium may include:

• Otoscopy and tympanometry to assess the middle ear and tympanic membrane
• Audiometry to evaluate hearing function
• Imaging studies (e.g., CT or MRI) to rule out other possible causes of symptoms

Treatment:

The treatment for adhesions of the drum head to promontorium depends on the underlying cause and may involve:

• Antibiotic therapy for otitis media or COME
• Surgical intervention to remove adhesions or repair the tympanic membrane
• Tympanoplasty or other surgical procedures to address middle ear pathology
