H70.003
Acute mastoiditis without complications, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Acute bilateral mastoiditis is a sudden and severe infection that affects both mastoid bones—large air-filled cavities located behind the ears. It often arises as a complication of untreated or severe middle ear infections. Recognized by its rapid onset and potential for serious complications, understanding this condition helps in early recognition and management.
Causes & Symptoms
Clinical Causes: Spread of infection from the middle ear (otitis media) Bacterial infections, commonly Streptococcus pneumoniae or Haemophilus influenzae Previous ear infections that were inadequately treated Surgical procedures involving the ear or surrounding areas Immunocompromised state increasing susceptibility to infections
Key Symptoms: Severe pain behind the ears, often worsening rapidly Swelling and redness behind the ears Fever and chills Hearing loss or muffled hearing Discharge from the ear if the infection affects the middle ear or breaks through the mastoid bone Tenderness when touching behind the ears General feeling of being unwell, fatigue, and malaise
Diagnostic & Treatment
Diagnosis Path: Physical examination focusing on the ears and surrounding area Otoscopic examination to assess the ears for signs of infection Imaging tests such as CT scan of the temporal bones to evaluate the extent of mastoid involvement Laboratory tests, including blood work to check for infection markers Microbiological cultures of ear discharge if present, to identify causative bacteria
Treatment Protocols: Hospitalization in most cases for close monitoring and IV antibiotics High-dose intravenous antibiotics aimed at the identified or likely bacteria Surgical intervention, such as mastoidectomy, may be necessary to drain infection or remove infected tissue Pain management with appropriate medications Addressing any complications, like abscess formation or spread of infection Follow-up imaging and examinations to ensure resolution
