Summary
A novel saline injection technique simplifies pericranial flap preparation for anterior cranial base surgery. This method enhances subgaleal layer visualization, aiding neurosurgeons in harvesting adequate flaps and minimizing tissue damage.
Area of Science:
- Neurosurgery
- Plastic Surgery
- Surgical Techniques
Background:
- Anterior cranial base surgery often necessitates reconstruction of cranial defects.
- The pericranial flap is a common method for such reconstructions.
Purpose of the Study:
- To present a straightforward technique for preparing pericranial flaps.
- To improve flap harvesting in anterior cranial base reconstruction.
Main Methods:
- Injecting saline into the subgaleal space of the scalp prior to incision.
- Utilizing saline-induced swelling to delineate tissue planes.
- Dissecting the flap using electrocautery and a surgical blade.
Main Results:
- Saline injection created visible scalp swelling, aiding localization.
- The technique facilitated flap harvesting with reduced risk of injury.
- Dissection in the subgaleal plane was improved, leading to a thickened flap.
Conclusions:
- The technique enhances subgaleal layer awareness for neurosurgeons.
- It simplifies dissection and reduces operative injury.
- This method is particularly useful for harvesting anteriorly based pericranial flaps, which can be challenging due to thinner frontal pericranium.
