A modified park bench position, the Dormeuse position, is introduced for retrosigmoid surgeries. This surgical approach reduces posterior fossa pressure, enhancing neural and vascular manipulation for improved cerebellopontine angle control.

Area of Science:

  • Neurosurgery
  • Surgical Positioning

Background:

  • Retrosigmoid approaches require precise patient positioning due to limited cisternal space.
  • Common positions include supine, semi-sitting, and park bench, each with unique benefits and drawbacks.

Purpose of the Study:

  • To introduce a modified park bench position for retrosigmoid surgery.
  • To evaluate the efficacy of this new position in improving surgical conditions.

Main Methods:

  • A modified park bench position, termed the Dormeuse position, was developed and utilized.
  • The position was assessed for its impact on posterior fossa pressure and surgical access.

Main Results:

  • The Dormeuse position effectively decreases posterior fossa pressure.

  • It facilitates optimal manipulation and control of neural and vascular structures within the cerebellopontine angle.

    • Conclusions:

    • The Dormeuse position offers significant advantages for retrosigmoid surgeries.
    • This technique enhances surgical safety and effectiveness by optimizing the operative environment.
