What does subperiosteal abscess mean?

Subperiosteal abscess is generally defined as the collection of pus between the periorbita and the orbital wall, and usually results from paranasal sinus infection. Early, appropriate evaluation and management observing signs and symptoms of orbital inflammation are required to prevent blindness.

What causes subperiosteal abscess?

ACUTE SINUSITIS of the ethmoid and maxillary complex is the most frequent cause of a subperiosteal abscess (SPA). The incidence of an SPA in orbital infections is about 15% in children.

When do you drain an orbital abscess?

Surgical drainage of an orbital abscess is indicated in any of the following instances: A decrease in vision occurs. An afferent pupillary defect develops. Proptosis progresses despite appropriate antibiotic therapy.

What is an orbital abscess?

Orbital abscesses are collections of pus within the orbital soft tissue. Diagnosis is confirmed by CT scan, but the physical signs of severe exophthalmos and chemosis, with complete ophthalmoplegia, as well as venous engorgement or papilledema on funduscopic examination, are suggestive. Orbital infections.

What is subperiosteal abscess in acute mastoiditis?

Subperiosteal abscess of the mastoid is one of the more frequent complications of acute otomastoiditis and results in coalescent mastoiditis extending through the external cortex of the mastoid sinus. This can occur in any direction: postauricular: common as the bone is particularly thin (“Macewen triangle”)

What is subperiosteal hematoma?

An injury might cause blood to build up in the area beneath the periosteum. This causes a subperiosteal hematoma, a type of bone bruise. An injury might also cause bleeding and swelling in the area between your cartilage and the bone beneath it. This causes a subchondral bone bruise.

What is Brodie’s abscess?

Brodie’s abscess is a sub-acute form of osteomyelitis, presenting as a collection of pus in bone, often with an insidious onset1. It’s first description in the medical literature was in 1832 by sir Benjamin Brodie during a lecture held for the Medical and Surgical Society2.

How do you treat a subperiosteal abscess?

The traditional treatment of subperiosteal orbital abscess consists of surgical drainage and antibiotic therapy.

What is orbital infection?

Orbital cellulitis is an infection of the soft tissues and fat that hold the eye in its socket. This condition causes uncomfortable or painful symptoms. It’s not contagious, and anyone can develop the condition. However, it most commonly affects young children. Orbital cellulitis is a potentially dangerous condition.

What causes orbital abscess?

Streptococcus species and Staphylococcus aureus are the most common types of bacteria that cause this condition. However, other bacterial strains and fungi can also be the cause of this condition. Orbital cellulitis in children ages 9 and under is usually caused by only one type of bacteria.

How do you get an orbital infection?

Orbital cellulitis usually is caused by spread of an infection to the orbit from the sinuses around the nose (nasal sinuses) but can also be spread from infection of the teeth or bloodstream. An animal or insect bite or another wound to the eyelids can also spread infection and lead to orbital cellulitis.

What is a Bezold abscess?

Bezold’s abscess is a rare deep neck abscess and is an intratemporal complication of a coalescent mastoiditis, wherein the infection erodes through the lateral mastoid cortex medial to the attachment of the sternocleidomastoid (SCM) muscle.

How are orbital cellulitis and subperiosteal abscess classified?

Chandler classification system: I, inflammatory edema (preseptal cellulitis); II, Orbital cellulitis; III, Sub Periosteal abscess; IV, Orbital abscess, and V, cavernous sinus thrombosis. Orbital Cellulitis commonly results from acute sinusitis & can lead to disastrous outcomes if not appropriately treated.

How does a CT show a subperiosteal abscess?

Pre-operative CT shows a left subperiosteal abscess with an air-fluid level. Mucopurulent material is drained from adjacent ethmoid and maxillary sinuses. Skeletonized lamina papyracea demonstrates a bony defect. Portion of lamina papyracea is removed for adequate drainage of the subperiosteal abscess.

Can a sinus abscess extend into the orbit?

More commonly occurs from ethmoidal sinusitis, extending into the orbit via the lamina papyracea but can also occur secondary to frontal sinusitis. 1. Liao JC, Harris GJ.

Can a thrombophlebitis cause an orbital abscess?

Other potential routes include local thrombophlebitis, or by way of infected emboli. As it progresses, it can lead to subperiosteal or orbital abscess. Other less common etiologies include dacryocystitis, retained orbital foreign body, periocular trauma and dental infection.
