The current study seeks to examine the association between chronic opioid use and postoperative outcomes for patients undergoing anterior cervical discectomy and fusion (ACDF) and posterior lumbar fusion (PLF). ⋯ Our analysis using a national administrative database showed that opioid dependence may be associated with worse economic outcomes for patients undergoing ACDF and PLF.

To evaluate prevalence and prognosis of postoperative coronal imbalance (CIB) and factors related to its onset and spontaneous improvement in patients with Lenke 5C adolescent idiopathic scoliosis who underwent selective thoracolumbar-lumbar fusion. ⋯ Although CIB was frequently detected in the early postoperative period after selective thoracolumbar-lumbar fusion, it mostly corrected spontaneously. Relatively younger age at surgery and less flexible lumbosacral curve may be related to postoperative CIB, and greater changes of LIV disc angle may be associated with spontaneous improvement of CIB.

Basilar artery occlusion (BAO) is a severe condition with high mortality. However, surgical procedures and outcomes of BAO with different pathologic subtypes have not been fully clarified. This study compared the surgical procedures and clinical outcomes of mechanical thrombectomy in different subtypes of BAO. ⋯ The outcome of endovascular treatment for BAO varies among patients with different pathologic mechanisms. Patients with embolism from tandem vertebral artery steno-occlusion achieved the best outcomes. Rescue treatment was more common in patients with embolic BAO with tandem vertebral artery steno-occlusion and BAO with in situ atherosclerotic thrombosis.

In recent decades, the ever-expanding use of endoscopes and development of dedicated instrumentation have reshaped the panorama of surgical approaches to the frontal sinus.1 Nonetheless, the far lateral portion of the sinus might still represent a concern, especially in cases with unfavorable or distorted anatomy.2,3 We report the case of a 52-year-old man, referred to our department for recurrent episodes of left orbital swelling and supraorbital headache, 3 months after Draf III frontal sinusotomy for marsupialization of multiple frontal mucoceles. Computed tomography and magnetic resonance imaging scans were consistent with persistent inflammatory tissue in the far lateral left frontal sinus. ⋯ The patient is asymptomatic after 16 months (Video 1). The transorbital approach is effective in managing orbital and frontal sinus diseases,6 and the combination with the endonasal route grants complete access to the frontal sinus, even in cases of high pneumatization and lateral extension.4,7 Multiportal transorbital approaches represent additional techniques in the rhinologist's surgical armamentarium, which can overcome the limits of a single port approach.8,9 Reports on their use providing technical hints and critical considerations are to be encouraged to ease and stimulate the surgical training in this field.

The occipital transtentorial approach (OTA) is a very useful but challenging approach to expose the pineal region because the deep-seated arachnoid membranes usually fold and extend over the great vein of Galen (GVG), leading to dense and poor visibility. In addition, the practical aspects of arachnoid anatomy are not well understood. We aimed to develop a safe surgical procedure for the OTA according to the practical aspects of arachnoid anatomy. ⋯ A 2-layered arachnoid structure interposes the GVG from above and below the tentorium. The arachnoid membrane below the tentorium can be peeled off bluntly from the GVG to the attachment bundle limited by the penetrating veins. This detachment technique is useful for safe enlargement of the surgical field for the OTA.
