Summary
This study introduces a novel, cost-effective pterional craniotomy fixation method using absorbable clamps and fibrin glue. The technique ensures excellent bone fusion and satisfactory esthetic outcomes, avoiding complications associated with traditional titanium plates.
Area of Science:
- Neurosurgery
- Plastic Surgery
- Biomaterials
Background:
- Pterional craniotomy is popular, but postoperative deformities are a concern.
- Titanium plates offer simple fixation but can lead to complications like infection and failed skull growth.
- Existing methods necessitate improvements for cost-effectiveness and esthetics.
Purpose of the Study:
- To develop a simple, cost-effective, and esthetically pleasing fixation method for pterional craniotomy.
- To evaluate a technique using absorbable clamps and fibrin glue, avoiding non-metallic materials.
- To assess the long-term outcomes of this novel fixation approach.
Main Methods:
- Six patients (young and older) underwent pterional craniotomy with CranioFix Absorbable clamps for bone flap fixation.
- Bone chips and dust were secured in the bone gap using fibrin glue.
- Computed tomography (CT) values and temporal profile thickness were measured postoperatively.
Main Results:
- Complete bone fusion was observed in all patients within one year.
- Temporal muscle thickness and temporal profile thickness showed minimal changes (within 2 mm) compared to preoperative measurements.
- The technique demonstrated effective bone flap fixation and healing.
Conclusions:
- The described osteoplastic cranioplasty technique offers a simple, cost-effective solution for pterional craniotomy.
- Gentle tissue handling and the use of absorbable clamps contribute to satisfactory esthetic results and surgical site rigidity.
- This method presents a viable alternative to traditional fixation techniques, minimizing complication risks.

01:14Cranial Bones: Superior and Posterior View
2.3K
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,...

01:27Cranial Bones: Lateral View
2.3K
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...
