H70.013
Subperiosteal abscess of mastoid, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
A bilateral subperiosteal abscess of the mastoid is a rare, serious condition involving the buildup of pus between the bone covering the mastoid process and the bone itself. This condition often results from a complication of an ear infection (otitis media) that extends into the mastoid region, which is located behind the ear. Recognizing and understanding this condition is crucial for effective management and treatment.
Causes & Symptoms
Clinical Causes: Chronic or severe middle ear infections (otitis media) Spread of infection from the middle ear to the mastoid process Spread of bacteria, viruses, or fungi causing inflammation and pus formation Previous ear surgeries or trauma that compromise the mastoid bone Immunocompromised state impairing the body's ability to fight infection
Key Symptoms: Pain behind both ears, often severe and persistent Swelling or tenderness behind the ears Fever and general malaise Hearing loss or a sensation of fullness in the ears Pus drainage from the ear(s) Tenderness or redness over the mastoid region Possible vertigo or dizziness if inner ear structures are involved Signs of systemic infection such as fatigue or chills
Diagnostic & Treatment
Diagnosis Path: Physical examination focusing on the ears, behind-the-ear area, and neurological signs Otoscopic examination of the ear canal and tympanic membrane Imaging tests such as CT scan of the temporal bones to visualize the extent of abscess formation and bone involvement Laboratory tests including blood work to identify infection markers and blood cultures Microbiological analysis of any pus drained from the ear
Treatment Protocols: Hospitalization for close monitoring and IV antibiotics targeting common causative bacteria Surgical drainage of the abscess to remove pus and reduce pressure Mastoidectomy procedures to remove infected mastoid air cells if necessary Supportive care including pain management and anti-inflammatory medications Follow-up imaging and audiology assessments to monitor healing Addressing underlying ear infections or predisposing factors to prevent recurrence
