Summary
Sphenoid sinus fractures are common after head trauma. While cerebrospinal fluid (CSF) leaks occur in 9% of cases, blunt carotid artery injury (BCAI) is rare, suggesting fracture pattern analysis aids in evaluating patients with sphenoid sinus fractures.
Area of Science:
- Neurosurgery
- Radiology
- Trauma Surgery
Background:
- Sphenoid sinus fractures are a frequent consequence of blunt head trauma.
- These fractures can lead to serious complications, including blunt carotid artery injury (BCAI) and cerebrospinal fluid (CSF) leaks.
- Existing literature lacks a thorough analysis of the association between sphenoid sinus fractures and these sequelae.
Purpose of the Study:
- To investigate the patterns of traumatic sphenoid sinus fractures.
- To evaluate the relationship between specific fracture patterns and the incidence of BCAI and traumatic nasal CSF leaks.
Main Methods:
- A retrospective review was conducted on 123 patients with sphenoid sinus fractures.
- Fracture classification was based on the involved sinus walls.
- Logistic and linear regression analyses were employed to assess associations between injury mechanisms, fracture locations, and outcomes.
Main Results:
- The most frequent fracture sites involved the carotid canal (60%), sphenoid roof (49%), and lateral wall (48%).
- Cerebrospinal fluid (CSF) leaks occurred in 9% of fractures, and blunt carotid artery injury (BCAI) in 1.6%.
- Sphenoid roof fractures showed a significant association with CSF leaks (OR=12.4, p=0.002), but no specific fracture subsite correlated with BCAI. Penetrating injuries were linked to CSF leaks (OR=24.7, p=0.01).
Conclusions:
- Nasal CSF leak is the most common complication of sphenoid sinus fractures, whereas BCAI is exceptionally rare.
- Identifying fracture patterns is crucial for guiding further patient evaluation.
- The high negative predictive value for CSF leaks and BCAI suggests that certain fracture patterns may indicate a lower risk.

01:27Cranial Bones: Lateral View
8.1K
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...

9.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:22Sutures of the Skull
14.6K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

9.2K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:27Fractures: Bone Repair
6.8K
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...
