OBJECTIVE A smartphone augmented reality (AR) application (app) was explored for clinical use in presurgical planning and lesion scalp localization. METHODS We programmed an AR App on a smartphone. The accuracy of the AR app was tested on a 3D-printed head model, using the Euclidean distance of displacement of virtual objects. For clinical validation, 14 patients with brain tumors were included in the study. Preoperative MRI images were used to generate 3D models for AR contents. The 3D models w...

BACKGROUND To better understand how anatomical features of Chiari malformation type 0 (CM0) result in the manifestation of Chiari malformation type 1 (CM1) signs and symptoms, we conducted a morphometric study of the posterior cranial fossa (PCF) and cervical canal in patients with CM1 and CM0. METHODS This retrospective study had a STROBE design and included 120 adult patients with MRI evidence of a small PCF (SPCF), typical clinical symptoms of CM1, and a diagnosis of CM1, CM0, or SPCF-TH0-onl...

BACKGROUND Surgical clipping of anterior communicating artery (ACoA) aneurysms remains challenging due to their complex anatomy. Anatomical risk factors for ACoA aneurysm surgery require further elucidation. The aim of this study is to investigate whether proximity of the midline perforating artery, subcallosal artery (SubCA), and associated anomaly of the ACoA complex affect functional outcomes of ACoA aneurysm surgery. METHODS A total of 92 patients with both unruptured and ruptured ACoA aneur...

BACKGROUND Idiopathic intracranial hypertension (IIH) is a rare disease of unknown aetiology related possibly to disturbed cerebrospinal fluid (CSF) dynamics and characterised by elevated intracranial pressure (ICP) causing optic nerve atrophy if not timely treated. We studied CSF dynamics of the IIH patients based on the available literature and our well-defined cohort. METHOD A literature review was performed from PubMed between 1980 and 2020 in compliance with the PRISMA guideline. Our study ...

BACKGROUND The development of specialized instruments and surgical techniques has enabled the biportal endoscopic system to access the foraminal and extraforaminal area using the contralateral sublaminar approach at the lumbar level. METHODS Biportal endoscopic contralateral sublaminar approach was used to resolve the contralateral foraminal, and extraforaminal stenosis at the lumbar level. Prominent syndesmophytes and herniated disc compression of the exiting nerve root were successfully remove...

BACKGROUND Incidence, prevalence, and long-term survival outcomes in patients with moyamoya angiopathy (MMA) according to stroke presentation type and age group have not been clearly elucidated. METHODS We investigated mortality in patients with MMA (moyamoya disease, probable moyamoya disease, moyamoya syndrome) of whose International Classification Disease 10 code was I67.5 from 2006 to 2015 using the Korean National Health Insurance database. MMA at diagnosis was classified into 3 types (isch...

BACKGROUND Deep surgical site infections (dSSIs) after instrumented spinal surgery pose major therapeutic challenges. Standard treatment involves surgical debridement, wound drainage, and long-term antibiotic administration. Autologous platelet-rich fibrin (PRF) constitutes a biomaterial obtained from patients' own blood that contains leukocytes, chemokines and growth factors boosting cicatrization. Due to favorable results reported from other surgical disciplines such as dentistry, orthopedics,...

PURPOSE Resection of clinoid meningiomas can be associated with significant morbidity. Experience with stereotactic radiosurgery (SRS) for clinoid meningiomas remains limited. We studied the safety and effectiveness of SRS for clinoid meningiomas. METHODS From twelve institutions participating in the International Radiosurgery Research Foundation, we pooled patients treated with SRS for radiologically suspected or histologically confirmed WHO grade I clinoid meningiomas. RESULTS Two hundred seve...

Intracranial germ cell tumors have an estimated incidence of 0.4-3.4% in the Western Hemisphere. Patients can present with a variety of differing clinical signs and symptoms including headache, nausea/vomiting, hydrocephalus, obtundation, pyramidal tract signs, and ataxia, hypothalamic/pituitary dysfunction. Rarely germ cell tumors can transform into alternative malignancy. In these cases, treatment options may be difficult. Metastasis to the brain is not uncommon in germ cell tumors and is freq...

BACKGROUND There is limited literature on technique full endoscopic pseudoarthrosis release of Bertolotti syndrome. METHODS Uniportal full endoscopic pseudoarthrosis release technique applies for patients presenting with symptomatic Bertolotti's syndrome. Full-thickness endoscopic drilling is carried out from most ventrolateral margin of pseudoarthrosis articulating with the highest part of sacral ala (PH) point to dorsal medioinferior margin of pseudoarthrosis adjacent to superior articular pro...
