Answer

After decompression, the syrinx is drained into the subarachnoid space through a longitudinal incision in the dorsal root entry zone (between the lateral and posterior columns), usually at the level of C2-C3.

Incision in the dorsal root entry area has the minimum risk of increasing neurological deficit.
