Area of Science:

  • Neurosurgery
  • Surgical Techniques

Background:

  • Traditional osteoplastic craniotomy often employs expensive microfixation systems.
  • These methods include miniplates, burr hole buttons, and ceramic dust for bone flap fixation.

Purpose of the Study:

  • To evaluate the efficacy of a cost-effective osteoplastic craniotomy technique.
  • To assess the cosmetic outcome and bone flap fusion using a chisel and hammer without specialized fixation devices.

Main Methods:

  • Osteoplastic craniotomy was performed on 15 patients (19 lesions) using a chisel and hammer.
  • Bone flaps were carefully cut and trimmed, minimizing bone defects.
  • The bone flap was secured with sutures, eliminating the need for additional fixation systems.

Main Results:

Related Experiment Videos

  • Follow-up imaging (skull X-ray, 3D-CT) demonstrated good bone flap fusion and normal configuration.
  • The mean follow-up period was 5 months.
  • Minor complications included two dural tears and two bony fractures.

Conclusions:

  • Osteoplastic craniotomy using a chisel and hammer provides a good cosmetic outcome.
  • This technique is a cost-effective alternative that does not require specialized instruments or fixation systems.
