Summary
Pterygoid plate fractures frequently occur with Le Fort fractures, but a significant portion are unrelated. Other craniofacial injuries, like sphenotemporal buttress or temporal bone fractures, commonly cause isolated pterygoid plate damage.
Area of Science:
- Craniofacial Surgery
- Radiology
- Trauma Medicine
Background:
- Pterygoid plate fractures are typically associated with Le Fort fractures.
- Understanding alternative fracture patterns is crucial for accurate diagnosis and treatment.
Purpose of the Study:
- To identify craniofacial fracture patterns, other than Le Fort fractures, that result in pterygoid plate injuries.
- To broaden the differential diagnosis for pterygoid plate fractures in trauma imaging.
Main Methods:
- Retrospective review of computed tomography (CT) scans.
- Analysis of 209 craniofacial trauma patients over a 5-year period.
- Categorization of pterygoid plate fractures based on associated injuries.
Main Results:
- 37.3% of pterygoid plate fractures were unrelated to Le Fort fractures.
- Associated injuries included sphenotemporal buttress fractures (33.3%), temporal bone fractures (23.1%), zygomaticomaxillary complex fractures (21.8%), and displaced mandible fractures (17.9%).
Conclusions:
- Approximately one-third of pterygoid plate fractures stem from injuries other than Le Fort patterns.
- Craniofacial surgeons must consider a wide range of potential causes when interpreting trauma CT scans for pterygoid plate fractures.

6.7K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.

01:27Cranial Bones: Lateral View
7.9K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

01:09Overview of the Axial Skeleton
13.6K
The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.

01:28Articulations of the Vertebral Column
3.7K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
