Area of Science:

Neurosurgery
Biomaterials Science
Craniofacial Reconstruction

Background:

A significant cranial bone defect presented aesthetic and functional challenges.
The defect exposed the brain, protected only by meninges and soft tissues.

Observation:

A 30-year-old male patient had a large cranial bone fragment absence.
This resulted in noticeable aesthetic deformity and potential functional impairment.

Findings:

A custom Polymethylmethacrylate (PMMA) prosthesis was fabricated to replicate the missing bone fragment.
A unique, oversized flask design utilizing a stainless steel instrument tray, screws, and a C clamp was employed due to the prosthesis size.

Implications:

This method offers a viable solution for large cranial defect reconstruction.
The use of PMMA provides a durable and aesthetically pleasing prosthetic option.
Custom fabrication techniques can overcome limitations of conventional methods in complex cases.
