Optimizing Burr Hole Placement for Craniotomy: A Technical Note

Area of Science:

• Neurosurgery
• Surgical Techniques

Background:

• Traditional craniotomy burr hole placement can lead to uneven bone margins and troughs.
• Minimizing burr holes is desirable for efficient dural separation.

Purpose of the Study:

• To describe a novel burr hole placement technique for craniotomy.
• To achieve smooth, beveled bony margins and minimize dural separation requirements.

Main Methods:

• Fifty craniotomies were performed with central burr hole placement instead of along the craniotomy line.
• Single burr hole for craniotomies < 9 cm, two for larger ones.
• Specialized bone cutter use for smooth, beveled edges.

Main Results:

• Single burr hole sufficed for 34/50 craniotomies (< 9 cm).
• Double burr hole technique used for 16/50 larger craniotomies (> 9 cm).
• All procedures completed without damaging dura or venous structures.

Conclusions:

• Optimally placed burr holes enable efficient craniotomy with fewer holes.
• This technique improves cosmetic results and prevents bone flap sinking.
