Background: Percutaneous endoscopic transforaminal discectomy (PETD) is usually chosen for lumbar disc herniation due to its obvious advantages such as small incision and absence of nerve or muscular traction. However, learning PETD is a great challenge for inexperienced surgeons. Objective: The study aimed to investigate whether isocentric navigation would be beneficial in PETD training. Methods: A total of 117 inexperienced surgeons were trained with PETD at L2/3, L3/4, L4/5, and L5/S1 on the cadavers without (Group A n=58) or with (Group B n=59) isocentric navigation...

Being a rare clinical entity, discal cyst presents indistinguishably from other causes of lower back pain and radiculopathy. It is an extremely rare pathology with unclear pathogenesis, indeterminate natural history with no consensus on the ideal management of the condition. We report a rare case of discal cyst in a patient who presented to our centre with localised low back pain and subsequently left sided radicular pain. With the aid of MRI and with clear surgical indication we proceeded with endoscopic removal of the cyst and intraoperatively confirmed its origin from the adjacent disc...

Neuroendoscopy has demonstrated safety and efficacy in the treatment of a host of pediatric neurosurgical pathologies. With the increase in its applicability, several associated complications have been described in the literature. A common practice in pediatric neurosurgery is the use of Gelfoam sponge pledget in the burr hole, followed by bone fragments and dust (obtained from the created burr hole), to cover the dural defect. This technique is used to enhance burr hole sealing and potentially prevent CSF leakage from the surgical site...

BACKGROUND: Intradural disc herniation is a rare entity with less than 0.3-1% of all disc herniations and at an L2-L3 level even rarer. The dural defects repairs on ventral aspect are technically challenging and may not be possible after durotomy hence many authors have placed fascia, muscle, or plugging by the hemostatic material. The surgical treatment of intradural disc herniation is usually posterior open surgery with formal durotomy to remove the disc fragments with good to fair results while the poorer outcome in late-presenting cases...

BACKGROUND: Sufficient decompression of the nerve root canal is still regarded as the method of choice when operating on patients with lumbar disc herniation (LDH) with lumbar lateral recess stenosis; however, tissue-sparing procedures are becoming more popular. Endoscopic techniques offer advantages and the benefits of rehabilitation, which have become the standard in many surgical operations when operating on the spine. A significant issue has been the upgrading of instruments to provide enough bone resection under continuous visual control...

Background: Endoscopic skull base surgery (ESBS) is a rapidly expanding field. Despite divergent reported preferences for reconstructive techniques and perioperative management, limited data exist regarding contemporary practice patterns among otolaryngologists performing ESBS. This study aims to elucidate current practice patterns, primarily the volumes of cases performed and secondarily a variety of other perioperative preferences. Methods: An anonymous 32-item electronic survey examining perioperative ESBS preferences was distributed to the American Rhinologic Society membership...

BACKGROUND: Residual disc fragments are observed on immediate postoperative magnetic resonance imaging (MRI) in 2.8-15% of patients after percutaneous endoscopic lumbar discectomy (PELD). Considering the known postoperative longitudinal outcomes in patients with residual disc tissue, a 'watchful waiting' strategy may be preferable to immediate re-operation in patients with asymptomatic residual disc material. OBJECTIVES: The aim of the present study was to compare the longitudinal clinical outcomes between PELD patients in whom the complete removal of disc fragments was achieved (complete group) and those in whom residual disc fragments were observed on postoperative MRI (residual group)...

BACKGROUND: Lumbar disc herniation (LDH) is being treated with limited indication by percutaneous full endoscopic lumbar discectomy. However, microscopic lumbar discectomy (MLD) is still considered as a gold standard. OBJECTIVE: With the advances in spinal endoscopic instruments and surgical techniques, all LDHs have now become operable with percutaneous full endoscopic lumbar discectomy procedure. We report the results of percutaneous full endoscopic lumbar discectomy (PELD) for all patients diagnosed with LDH, including severely difficult and extremely difficult LDH cases who visited our clinic with leg pain and lower back pain...

Xin Huang, Bin Zhu, Xiaoguang Liu
BACKGROUND: Percutaneous endoscopic lumbar discectomy (PELD) has become an increasingly popular minimally invasive spinal surgery. Due to the technical evolution of PELD, the focus of decompression has shifted from the central nucleus to the subannular-protruded disc herniation, which allows direct neural decompression. Surgical entry into the spinal canal leads to the greater possibility of bony structure obstruction, thus the location and direction of the working channel are crucial...

BACKGROUND: Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive surgery for the treatment of lumbar disc herniation (LDH) with a smaller incision, decreased damage to soft tissues, faster recovery, and fewer postoperative complications. However, the exactly epidemiological prevalence of recurrent herniation after PELD remains unclear. OBJECTIVES: To investigate the epidemiological prevalence of recurrent herniation in patients following PELD and to analyze the potentially related risk factors...

Adolescent lumbar disc herniation(ALDH) is clinically rare. Factors such as dysplasia, genetic factors, trauma, spinal sagittal aligment have been suspected as the pathogenesis of ALDH. The clinical features of ALDH are different from adult lumbar disc herniation: typical physical signs with minor complaints, higher proportion of lumbar deformities. ALDH usually involves one segment, presenting central type, and the herniated disc is larger with bone structure.Conservative treatment is suggested for ALDH patients without severe nerve injury...
