Area of Science:

  • Neurosurgery
  • Plastic and Reconstructive Surgery
  • Craniofacial Surgery

Background:

  • Reconstructing large cranial defects after multiple craniotomies is challenging due to scalp contraction.
  • Standard techniques may not be sufficient for effective and cosmetically pleasing closure.
  • Soft tissue expansion is the gold standard but not widely used by neurosurgeons.

Purpose of the Study:

  • To describe a simple external tissue expansion technique for large cranial defects.
  • To evaluate the morbidity and cosmetic satisfaction associated with this technique.

Main Methods:

  • Retrospective review of patients with large cranial defects (>5 cm) undergoing cranioplasty with preoperative tissue expansion using the DermaClose RC device.
  • Data collected included patient demographics, surgical history, radiation exposure, and complications.
  • Outcomes assessed included cerebrospinal fluid leak, meningitis, abscess, dermatitis, and patient satisfaction.

Main Results:

  • Six patients (5 female, 1 male) with complex factors like infections and radiation underwent the procedure.
  • All patients received preoperative tissue expansion followed by cranial bone reconstruction.
  • No patients experienced cerebrospinal fluid leak, meningitis, intracranial abscess, or dermatitis; all reported high cosmetic satisfaction.

Conclusions:

  • Preoperative scalp tissue expansion with the DermaClose RC device is a simple and reliable method for complex cranial reconstruction.
  • The technique is associated with low morbidity rates.
  • High patient satisfaction was achieved with this approach.
