Summary
This study analyzed infraorbital canal anatomy using CT scans to improve infraorbital nerve block success. Puncture depth varied significantly between left and right sides, but other measurements showed no significant differences.
Area of Science:
- Anatomy
- Radiology
- Medical Imaging
Background:
- The infraorbital canal's precise anatomical parameters are crucial for successful infraorbital nerve blockade.
- Accurate pre-procedural evaluation can enhance surgical outcomes and patient safety.
Purpose of the Study:
- To precisely evaluate the initial position and direction of the infraorbital canal.
- To analyze anatomical parameters of the infraorbital canal for improved infraorbital nerve blockade success rates.
Main Methods:
- Utilized 64-slice computed tomography (CT) with multiplanar reconstruction (MPR) on 224 normal infraorbital canals (112 individuals).
- Measured six key indicators: canal length, puncture depth, distance to nasal septum, distance to infraorbital rim, and angles relative to Frankfort and sagittal planes.
Main Results:
- A statistically significant difference was observed in the puncture depth between the left and right sides.
- No statistically significant differences were found in other measured parameters between left and right sides or between males and females.
Conclusions:
- CT-based analysis of infraorbital canal parameters provides valuable anatomical insights.
- Understanding these anatomical variations, particularly puncture depth, can optimize infraorbital nerve block procedures.

01:27Cranial Bones: Lateral View
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...

01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
01:14Cranial Bones: Superior and Posterior View
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,...
