Surgical Approaches in the Treatment of Intracranial Complications of Paranasal Sinus Disease: A Review of the Literature.
Intracranial extension of frontal or ethmoid sinusitis carries a high morbidity and mortality if not treated aggressively. With the emergence of endoscopic sinus surgery (ESS), we questioned whether these approaches have supplanted traditional transcranial procedures for intracranial extension of sinus disease, and whether ESS approaches had a difference in patient outcomes. ⋯ Combined ESS and transcranial approaches achieve definitive control of sinogenic and intracranial disease, whereas either modality alone carries a potential risk for higher morbidity and mortality. The use of ESS alone may have use in the treatment of sinusitis with posterior table erosion prior to intracranial extension.

Lateral interbody fusion (LIF) is an effective adjuvant for circumferential minimally invasive surgery (CMIS) treatment of adult spinal deformity (ASD). Accessing L5-S1 via an oblique LIF (OLIF) approach (OLIF 5-1) allows for anterior LIF (ALIF) at the lumbosacral junction without repositioning the patient. We review the early outcomes and complications of OLIF 5-1 at the bottom of a long construct for an MIS approach to treat ASD. ⋯ A single-position MIS OLIF 5-1 at the bottom of a long construct in conjunction with multilevel pre-psoas LIF seems to be a safe and effective technique for improving SL, global LL, and SVA with a low risk of perioperative and postoperative complications.

To describe the learning curve of pedicle screw placement using robot-assisted spine surgery of an experienced neurosurgeon and 2 supervised neurosurgical fellows. ⋯ Robot-assisted spine surgery is a safe, accurate method of pedicle screw instrumentation. Our data show similar learning adaptation rates for the first fellow and the experienced surgeon. Techniques learned by the attending surgeon were immediately transferable to a new learner, who was able to achieve a faster learning curve than both the first fellow and the experienced surgeon.

Three new 0.071-inch and 0.072-inch aspiration catheters have been introduced for stroke thrombectomy. Their comparative efficacy has not been clinically evaluated. ⋯ In comparing the newest large bore aspiration catheters, similar angiographic efficacy is achieved.

To evaluate effectiveness and safety of extended laminoplasty for the treatment of ossification of posterior longitudinal ligament (OPLL) involving the C2 segment. ⋯ If decompression indication for cases with OPLL involving the C2 segment was appropriate, extended laminoplasty up to the C2 segment could provide satisfactory neurologic recovery and would not accelerate cervical or segmental malalignment progression.
