Area of Science:

  • Neurosurgery
  • Oncology
  • Skull Base Surgery

Background:

  • Skull base tumors present complex surgical challenges.
  • Radical resection is crucial for favorable outcomes.
  • Minimally invasive approaches are continually being developed.

Purpose of the Study:

  • To design convenient lateronasal and infrafrontal approaches or lateronasal subvolution approach.
  • To achieve radical resection of skull base tumors involving the cranial cavity.

Main Methods:

  • Surgical resection of skull base tumors in 29 patients (22 malignant, 6 benign, 1 cyst, 1 meningoencephalocele) from 1987-1994.
  • Utilized lateronasal and infrafrontal approaches, and nasal columella lateral subvolution.
  • Reconstruction of bony and dural defects using musculocutaneous, galeal, pericranial, and autofascia lata flaps.

Main Results:

  • Effective prevention of meningoencephalocele and cerebrospinal fluid leaks with flap reconstruction.
  • 36.4% of malignant tumor patients were alive and disease-free at 3-7 years.
  • Complete cure achieved in benign tumor, cyst, and meningoencephalocele cases.

Conclusions:

  • Frontal musculocutaneous and pericranial flaps offer advantages over free bone grafts.
  • These flaps are associated with easier survival and operation.
  • Absence of osteonecrosis and exclusive reaction are key benefits.
