Insights
This study maps precise craniofacial pressure points for controlling bleeding. Identifying these key arterial sites improves first-aid effectiveness and hemorrhage control training.
Area of Science:
- Anatomy
- Medical Imaging
- Emergency Medicine
Background:
- Controlling craniofacial bleeding with pressure on arteries is vital in first aid.
- Precise anatomical locations for arterial pressure points are not well-defined.
Purpose of the Study:
- To precisely identify and map optimal pressure points on key craniofacial arteries.
- To provide anatomical guidance for effective hemorrhage control in emergencies.
Main Methods:
- Retrospective analysis of 201 adult CTA scans, 3D postprocessed.
- Mapping of facial, superficial temporal, occipital, transverse facial, and posterior auricular arteries.
- Utilized coordinate systems anchored at specific facial and occipital landmarks to determine pressure point locations.
Main Results:
- Identified ten bilateral pressure points, consistently accessible for compression.
- Facial and occipital artery points are further from landmarks than superficial temporal, transverse facial, and posterior auricular arteries.
- Over 95% of superficial temporal, transverse facial, and posterior auricular points are addressable with a single gesture.
Conclusions:
- An atlas of craniofacial pressure points provides practical anatomical guidance for first responders.
- Enhances hemorrhage control training programs, with potential for simulation and augmented reality applications.
Background:
Applying pressure to key points proximal to craniofacial arteries can arrest bleeding in first aid, but precise locations are poorly defined. This study investigates the precise pressure points within the craniofacial region.
Methods:
The authors retrospectively reviewed CTA scans from 201 adults, 3D postprocessed in HOROS. The facial, superficial temporal, occipital, transverse facial, and posterior auricular arteries were analyzed. Three coordinate systems-anchored at the angulus oris, the porus acusticus externus, and the external occipital protuberance-were used to map the optimal compression site. The authors measured the linear distance from each landmark to its pressure point and recorded vessel diameters. All measurements were bilateral and averaged across the cohort; interindividual variability was also analyzed.
Results:
Ten bilateral pressure points were identified and found to lie consistently within reach of thumb or 2-finger compression. Points for the facial and occipital arteries sit farther from their landmarks-along the mandible and posterior scalp-than those for the superficial temporal, transverse facial, and posterior auricular arteries. The latter 3 cluster along the auricular contour, such that a single compressive gesture can address over 95% of these points. Although most subjects exhibited consistent arterial courses, anatomic variations in branching patterns of the facial, transverse facial, and occipital arteries may necessitate palpation for pulsation before applying pressure.
Conclusions:
This atlas of craniofacial pressure points offers practical, anatomically precise guidance for first-aid responders and can enrich hemorrhage-control training programs, with potential for incorporation into simulation and augmented-reality tools.

01:14Cranial Bones: Superior and Posterior View
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,...

01:27Cranial Bones: Lateral View
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...

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...
