ICD-10: H70.891

ICD-10 code H70.891 refers to "Other mastoiditis and related conditions, right ear." This classification falls under the broader category of mastoiditis, which is an infection or inflammation of the mastoid process, the bony prominence located behind the ear. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of H70.891

Definition

Mastoiditis is primarily characterized by the inflammation of the mastoid air cells, which are small cavities within the mastoid bone. This condition often arises as a complication of acute otitis media (middle ear infection) but can also occur independently due to other infections or conditions affecting the ear.

Symptoms

Patients with mastoiditis may present with a variety of symptoms, including:
- Ear Pain: Often localized to the affected ear, which may be severe.
- Swelling: Redness and swelling behind the ear, particularly over the mastoid area.
- Fever: Elevated body temperature indicating an infection.
- Hearing Loss: Temporary or permanent hearing impairment may occur due to the infection's impact on the ear structures.
- Discharge: Purulent (pus-like) discharge from the ear canal may be present, especially if there is a concurrent ear infection.

Causes

The primary cause of mastoiditis is usually a bacterial infection that spreads from the middle ear. Common pathogens include:
- Streptococcus pneumoniae
- Staphylococcus aureus
- Haemophilus influenzae

Other factors that may contribute to the development of mastoiditis include:
- Chronic ear infections: Recurrent episodes of otitis media can lead to chronic inflammation and infection of the mastoid.
- Immunocompromised states: Individuals with weakened immune systems are at higher risk for infections.

Diagnosis

Diagnosis of mastoiditis typically involves:
- Clinical Examination: Assessment of symptoms and physical examination of the ear.
- Imaging Studies: CT scans or MRI may be utilized to visualize the extent of the infection and assess for complications such as abscess formation.
- Culture Tests: Ear discharge may be cultured to identify the causative organism.

Treatment

Treatment for mastoiditis generally includes:
- Antibiotics: Broad-spectrum antibiotics are often initiated to combat the infection.
- Surgery: In cases where there is an abscess or if the infection does not respond to medical treatment, surgical intervention (mastoidectomy) may be necessary to drain infected material and remove diseased tissue.

Complications

If left untreated, mastoiditis can lead to serious complications, including:
- Hearing Loss: Permanent damage to the auditory structures.
- Intracranial Infections: Such as meningitis or brain abscesses, which can be life-threatening.
- Facial Nerve Palsy: Due to the proximity of the mastoid to the facial nerve.
