To compare the clinical outcomes of patients with recurrent lumbar disk disease undergoing percutaneous endoscopic lumbar diskectomy or minimally invasive transforaminal lumbar interbody fusion at a single clinic. ⋯ Both PELD and MIS-TLIF showed favorable clinical outcomes for recurrent disk herniation. Compared with MIS-TLIF, PELD has the following several advantages: 1) performed under local anesthesia; 2) performed with very few approach-related complications, such as dural tear; and 3) rare possibility of fusion disease, such as adjacent segment. However, PELD is also faced with several problems, such as 1) the relative higher rate of postoperative long-term chronic low back pain, and (2) the possibility of recurrence, despite the opportunity being low.

An extensive frontal resection is a frequently performed neurosurgical procedure, especially for treating brain tumor and refractory epilepsy. However, there is a paucity of reports available regarding its surgical anatomy and technique. ⋯ FLD is an anatomy-based surgical technique for extensive frontal lobe resection. It presents reliable anatomic landmarks, selective gray matter removal, preservation of frontal horn, and low complication rate in our series. It can be an alternative option to the classical frontal lobectomy.

Even although microvascular decompression is the standard treatment for hemifacial spasm (HFS), the treatment is not always 100% successful. Some patients experience the reappearance of HFS after temporary relief after surgery. We analyzed our data to elucidate the reasons for and prognosis of HFS reappearance, specifically focusing on exact compressive location of the facial nerve. ⋯ After microvascular decompression for HFS, almost half of the patients experienced transient HFS recurrence despite sufficient decompression of the facial nerve. However, in most cases, recurrent HFS gradually resolved over a period. Based on the compression location, the surgeon could anticipate recurrence of transient HFS.

The relationship between the use of an endoscope during ventriculoperitoneal shunt (VPS) procedures and infection remains poorly defined. In this study, we sought to analyze whether the simultaneous use of an endoscope could in fact increase the infection rate associated with VPS procedures. ⋯ In the present study, the use of an endoscope during VPS procedures did not increase the risk of surgical infection.

This report portrays our pitfall in the initial diagnosis of an intracranial arterial dissection that we misinterpreted as a saccular aneurysm. Intracranial arterial dissections presenting with convexity subarachnoid hemorrhage are rare, thus being easily mistaken with mild traumatic head injuries and therefore preventing transfer to a tertiary hospital. ⋯ Thrombus within the dissected segment can be mistaken by vasospasm and may even reveal fake images of saccular aneurysms, thus prompting inadequate endovascular or surgical treatment. The case reported here illustrates all these likely pitfalls in the diagnosis and management of intracranial arterial dissections.
