Psychosurgery

28
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.

Cranial Bones: Superior and Posterior View

1.8K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Area of Science:

  • Craniofacial Surgery
  • Pediatric Neurosurgery
  • Plastic and Reconstructive Surgery

Background:

  • Craniopagus twins present complex surgical challenges due to shared cranial structures.
  • Effective soft tissue coverage is critical for successful separation and reconstruction outcomes.

Purpose of the Study:

  • To describe a novel, single-stage surgical approach for cranial separation and reconstruction in partial angular craniopagus twins.
  • To evaluate the efficacy of a custom-designed tissue expander in facilitating soft tissue coverage.

Main Methods:

  • A custom-designed, wedge-shaped tissue expander was utilized in 6-month-old twins with partial angular craniopagus.
  • The expander was placed to leverage the unique anatomy, expanding against a rigid bone strip for high-volume scalp expansion.
  • Virtual and physical soft tissue modeling were employed for planning incision lines and flap designs.
  • Infants underwent single-stage cranial separation and soft tissue closure at 10 months old.

Main Results:

  • Successful cranial separation and reconstruction were achieved in the craniopagus twins.
  • High-volume scalp expansion was accomplished using the custom expander against a stable bony base.
  • Native expanded scalp tissue was sufficient for complete soft tissue closure.

Conclusions:

  • The presented surgical approach, utilizing a custom tissue expander and advanced modeling, is effective for cranial separation and reconstruction in craniopagus twins.
  • This method facilitates adequate soft tissue coverage, crucial for successful surgical outcomes in complex conjoined twin cases.
