A dual-port endoscopic approach, used for the surgical management of colloid cysts, was developed with the following goals: 1) a direct, unobstructed, high-illumination endoscopic view of the attachment point of the colloid cyst to the tela choroidea, and 2) a gross total resection of the colloid cyst capsule using microsurgical techniques. ⋯ The dual-port endoscopic technique described is an alternative to classic microsurgical craniotomy approaches. The technique allows excellent visualization of the colloid cyst attachment and permits microdissection techniques.

In recent years, percutaneous laser disc decompression (PLDD) has become a routine surgical procedure because it can be performed under local anesthesia and is minimally invasive. However, there is a risk of nerve root and endplate injury owing to heat generated by laser irradiation during PLDD. We recently performed salvage surgery on a patient with heat injury to the L5 nerve root that developed after PLDD. ⋯ When salvage surgery is performed after a PLDD procedure, disc and nerve root injuries owing to laser heat energy must be considered.
