Surgical Techniques

Background:

Decompressive craniectomy is a standard procedure for managing intracranial pressure.
The "floating anchored" craniotomy is an alternative technique developed at a tertiary neurosurgery institution.
Hypothesized benefits include adequate decompression, reduced intracranial pressure, and avoidance of secondary cranioplasty.

Purpose of the Study:

To evaluate the efficacy and potential advantages of the floating anchored craniotomy compared to traditional decompressive craniectomy.
To assess the floating anchored craniotomy's applicability as an alternative to decompressive craniectomy.

Main Methods:

A retrospective analysis of prospectively collected data from 57 consecutive patients.
The floating anchored craniotomy involves re-attaching the bone plate with loosely affixed sutures to allow for decompression and anatomical repositioning post-edema.

Main Results:

The floating anchored craniotomy demonstrated comparable intracranial pressure reduction to decompressive craniectomy.
The technique offers significant theoretical advantages, including maintained bone protection and prevention of the syndrome of the trephined.

Conclusions:

The floating anchored craniotomy may be a viable alternative to decompressive craniectomy.
Despite potential benefits, techniques avoiding secondary cranioplasty have seen limited adoption and exclusion from major trials.
