Bezold Abscess: Causes and Treatment
In the realm of otolaryngology, Bezold abscess presents as a rare but significant complication associated with untreated or inadequately treated mastoiditis. First identified by Friedrich Bezold in 1881, this condition underscores the critical importance of timely intervention in infections of the mastoid bone. We provides a comprehensive overview of Bezold abscess, encompassing its causes, symptoms, diagnosis, treatment, and potential complications.
What is a Bezold Abscess?
Bezold abscess is a deep neck abscess that occurs when pus from an infected mastoid air cell invades the soft tissues of the neck. The condition typically arises following the erosion of the mastoid tip, allowing the purulent material to track into the sternocleidomastoid muscle sheath and beyond. This unusual descent of infection is what characterizes the abscess, setting it apart from other mastoiditis complications.
Causes of Bezold Abscess
Origin in Mastoiditis
The primary precursor to Bezold abscess is mastoiditis, an infection of the mastoid process of the temporal bone. The mastoid bone, located behind the ear, contains air cells that can become inflamed and infected, usually as a complication of acute otitis media (middle ear infection). When the infection is not adequately managed, it can lead to the formation of a Bezold abscess.
Pathophysiology
The pathophysiological mechanism involves the erosion of the thin cortical bone of the mastoid, which permits the infection to extend beyond its usual confines. This breach results in the spread of infectious material into the surrounding neck tissues, particularly beneath the sternocleidomastoid muscle, leading to abscess formation.

Get A Second OpinionSymptoms of Bezold Abscess
The clinical presentation of Bezold abscess can be varied, but several symptoms are commonly observed:
- Neck Swelling: A notable swelling in the upper neck region is often present, which may be tender and warm to the touch.
- Pain: Persistent pain in the neck and behind the ear is a frequent complaint.
- Fever: Patients often exhibit febrile episodes due to the underlying infection.
- Reduced Neck Mobility: The presence of an abscess may restrict neck movements.
- Hearing Loss: Conductive hearing loss might occur due to the associated middle ear pathology.
Diagnosing Bezold Abscess
Clinical Examination
Initial diagnosis often begins with a detailed clinical examination, focusing on the history of mastoiditis or persistent ear infections and the presence of neck swelling and pain.
Imaging Studies
- CT Scan: A computed tomography (CT) scan of the temporal bone and neck is crucial for confirming the diagnosis. It helps visualize the extent of the abscess and any erosion of the mastoid process.
- MRI: Magnetic resonance imaging (MRI) can provide additional detail regarding the involvement of soft tissues and the spread of infection.
Laboratory Tests
Blood tests may reveal leukocytosis and elevated inflammatory markers, supporting the diagnosis of an ongoing infection.
Treatment of Bezold Abscess
The management of Bezold abscess requires a multidisciplinary approach involving otolaryngologists and, at times, infectious disease specialists.
Medical Management
- Antibiotics: Broad-spectrum intravenous antibiotics are the cornerstone of initial management. The antibiotic regimen is often adjusted based on culture results from aspirated pus.
Surgical Intervention
- Mastoidectomy: A mastoidectomy is often performed to remove the infected mastoid air cells and prevent further spread of infection. This procedure involves the surgical excision of the mastoid bone and drainage of the abscess.
- Neck Exploration and Drainage: In cases where the abscess has significantly extended into the neck, surgical drainage may be necessary to remove the purulent collection and alleviate symptoms.
Postoperative Care
Post-surgical care includes continued antibiotic therapy and regular follow-up to monitor the resolution of the infection and prevent recurrence.

Book an AppointmentComplications of Bezold Abscess
If not treated promptly, Bezold abscess can lead to several serious complications:
- Deep Neck Space Infections: The abscess may extend into other deep neck spaces, causing further complications.
- Thrombophlebitis: Inflammation of the veins in the neck can occur, leading to potentially life-threatening conditions such as Lemierre's syndrome.
- Facial Nerve Palsy: The infection can affect the facial nerve, leading to paralysis.
- Intracranial Extension: Rarely, the infection may spread intracranially, resulting in conditions such as meningitis or brain abscess.
Preventive Strategies
Preventing Bezold abscess primarily involves the timely and effective treatment of acute otitis media and mastoiditis. Ensuring complete resolution of these infections with appropriate antibiotics and, if necessary, surgical intervention is key.
