Summary
This study demonstrates the feasibility of using exoscopic magnification for the pericranial-onlay technique in alloplastic cranioplasties. This advanced approach ensures safe and successful dissections, even in complex cases requiring cranial reconstruction.
Area of Science:
- Neurosurgery
- Plastic Surgery
- Surgical Technology
Background:
- The pericranial-onlay technique is used for alloplastic cranioplasties, creating a surgical plane under the galeal fascia.
- This technique involves dissection within the loose areolar tissue above the pericranium.
Purpose of the Study:
- To assess the feasibility and applicability of the pericranial-onlay technique for elective cranioplasties using exoscopic magnification (EM).
Main Methods:
- A retrospective consecutive case series included patients aged 18+ undergoing elective alloplastic cranioplasty for skull defects.
- The pericranial-onlay technique was employed, with dissection performed under exoscopic magnification (EM).
Main Results:
- Eleven patients (23-68 years) underwent successful cranioplasty using the pericranial-onlay technique under EM.
- Many patients had prior surgeries (7/11), existing hardware (7/11), or scalp infections (5/11).
- Mean operative time was 145.4 minutes; mean follow-up was 13.1 months, with only one non-technique-related complication.
Conclusions:
- This study is the first to report on pericranial-onlay execution using 3D exoscopic magnification (EM).
- EM facilitates meticulous, safe, and successful dissection, particularly in challenging cranial reconstruction cases.
- The use of EM enhances the surgical approach to the scalp, advancing cranial reconstruction techniques.
