What is the maxillary antrum?

What is the maxillary antrum?

The maxillary sinus (also called the maxillary antrum) is a pyramidal cavity (see Figs. The base of the pyramid is composed of the medial wall, which separates the maxillary sinus from the nasal cavity, and the apex is in the zygomatic process. Superiorly, the floor of the orbit forms the roof of the antrum.

How is a maxillary fracture treated?

Maxillary (Le Fort) fracture: Open reduction with internal fixation is the standard. If CSF rhinorrhea is present, a neurosurgeon should be consulted. Prophylactic antibiotics are warranted if the fracture extends through the tooth-bearing region or through the nasal or sinus mucosa.

What is left maxillary antrum?

The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, and drains into the middle meatus of the nose through the osteomeatal complex.

What happens when a foreign body enters the maxillary sinus?

Foreign bodies into the maxillary sinus may cause infectious complications due to the contact of the foreign body with the mucosa of the sinus interior, mainly, acute or chronic sinusitis. Local infection around the area may cause resorption of surrounding bone in the future.

Can maxillary fractures heal on their own?

Your doctor may recommend alternatives if the fracture isn’t serious enough to require surgery and will heal on its own. In this case, you may need to simply eat soft foods to allow your jaw to heal and see your doctor frequently for check-ups to monitor the maxilla’s healing.

How long does it take for a cheek fracture to heal?

Even if a fracture is held in place with plates and screws it still takes approximately six weeks for your cheekbone to heal completely. During this recovery period, you will need to be careful to avoid an injury to this area of your face, as it may cause the cheekbone to move out of position.

What are 3 signs of a fracture?

What Are the Symptoms of a Broken Bone?

• Swelling or bruising over a bone.
• Deformity of an arm or leg.
• Pain in the injured area that gets worse when the area is moved or pressure is applied.
• An inability to bear weight on the affected foot, ankle, or leg.
• Loss of function in the injured area.

What is a maxillary sinusotomy?

Maxillary antrostomy is a surgical procedure to enlarge the opening (ostium) of the maxillary sinus. This allows for further surgical intervention within the maxillary sinus cavity as well as improved sinus drainage.

How do you remove a foreign body from a maxillary sinus?

Two main surgical approaches are currently used for the removal of foreign bodies in the maxillary sinus: the bone flap and the endoscopic sinus techniques. The best treatment option to remove displaced implants into the maxillary sinus is the functional endoscopic sinus surgery.

The maxillary antrum is closely related to the roots of the maxillary premolar and molar teeth and is frequently visualized on oral and facial radiographs. The signs and symptoms of antral disease may mimic those of dental disease (and vice versa).

What is the flap valve of the lateral maxillary antrum?

The lateral maxillary antrum fragments form a “flap valve” trapping portions of the buccal fat pad within the antrum. Note a minimally displaced fracture of the left lateral pterygoid plate. Other images (not shown) demonstrated minimally displaced fractures of the left lateral orbital wall and left zygomatic arch.

Which CT findings are characteristic of left maxillary antrum fractures?

Axial CT image reveals fractures of the lateral and anterior walls of the left maxillary antrum. Herniation of low attenuation fat into the maxillary sinus is evident. The lateral maxillary antrum fragments form a “flap valve” trapping portions of the buccal fat pad within the antrum.

What are the possible complications of Dentistry in the maxillary molar region?

Dental surgery in the maxillary molar and premolar region may be complicated by the creation of an oroantral communication, the displacement of whole teeth, roots or other foreign bodies into the antrum or a fracture of the maxillary tuberosity. Antral disease may cause facial pain and the antral wall may be fractured during facial trauma.
