H70.13
Chronic mastoiditis, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Chronic bilateral mastoiditis is a prolonged inflammation of the mastoid bones, which are located behind the ears. This condition involves both sides of the mastoid areas and can develop from ongoing ear infections or unresolved acute mastoiditis. Recognized under ICD-10 code H70.13, this disease affects the air cells within the mastoid bone, leading to symptoms that can impact hearing and overall ear health. Early diagnosis and management are essential to prevent complications and preserve ear function.
Causes & Symptoms
Clinical Causes: Persistent middle ear infections (chronic otitis media) that spread to the mastoid air cells Repeated episodes of acute mastoiditis that do not fully resolve Poor drainage of middle ear fluids leading to chronic inflammation Structural abnormalities in the ear or mastoid bone that hinder natural drainage Weakened immune system, increasing susceptibility to infections
Key Symptoms: Persistent ear pain or tenderness behind the ears Swelling or redness behind the ear(s) Hearing loss in affected ears Drainage of pus or fluid from the ear(s) A feeling of fullness or pressure in the ears Fever and general malaise in some cases Possible dizziness or balance disturbances if the infection affects nearby structures
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a thorough physical examination, including otoscopy to visualize the ear canal and eardrum. Imaging studies such as CT scans are essential to assess the extent of mastoid bone involvement, identify any abscesses or bone destruction, and confirm bilateral involvement. Audiometry may be conducted to evaluate hearing loss. Medical history and symptom assessment are important components of establishing an accurate diagnosis.
Treatment Protocols: Management of chronic bilateral mastoiditis often requires a combination of medical and surgical approaches. Antibiotic therapy is the first step in controlling infection, typically prescribed based on culture results. In cases where medications do not resolve the condition, surgical interventions such as mastoidectomy may be necessary to remove diseased tissue, drain abscesses, and restore normal ear function. Supportive care, including pain management and ear hygiene, can aid recovery. Regular follow-up is recommended to monitor for recurrence or complications.
