Comparison between olfactory bulb and olfactory tract implantations through an endoscopic supraorbital keyhole approach: a cadaveric study - Summary - MDSpire
To compare the feasibility and stability of electrode implantation on the olfactory bulb (OB) versus the olfactory tract (OT) using a supraorbital keyhole approach (SKA) in human cadavers, emphasizing the comparative aspect of the study.
Key Findings:
Successful implantation on the dorsal OB was achieved in all cases, but electrode stability was poor, indicating a need for improved stabilization techniques.
Access to the OT was successful without the need for drilling the orbital roof, leading to reduced operative time, which may enhance surgical efficiency.
The ventral OT implantation provided a more stable and less invasive approach compared to the dorsal OB, suggesting a potential shift in surgical practice.
Interpretation:
The study suggests that ventral OT implantation may offer a more stable and less invasive alternative to dorsal OB implantation for olfactory neurostimulation, highlighting its potential clinical significance.
Limitations:
The study was conducted on cadavers, which may not fully replicate live surgical conditions, potentially affecting the applicability of the results.
Small sample size limits the generalizability of the findings, indicating a need for further studies with larger cohorts.
Conclusion:
Ventral OT implantation through a supraorbital keyhole approach is feasible and may provide advantages over dorsal OB implantation in terms of stability and invasiveness, warranting further investigation in clinical settings.
