Surgical treatment and outcomes of intramedullary tumors by minimally invasive approach.

Intramedullary tumors are uncommon neoplasms which, without treatment, can cause neurologic morbidity or mortality. The goal of the treatment is complete surgical resection with a minimally invasive approach while preserving neurological status and also spinal stability. Out of 1972 patients with tumors of the spinal canal treated between 1994 and 2017, 168 intramedullary tumors of 417 intradural tumors have been presented.

Diagnosis and Treatment of Transforaminal Epidural Steroid Injection in Lumbar Spinal Stenosis.

Objectives: Transforaminal epidural steroid injection reduces the low back-leg pain and enables daily activities of the patients. In this study, we aim to evaluate the treatment of transforaminal epidural steroid injection for lumbar spinal stenosis, which was mainly performed for lumbar disc herniation and share our diagnostic experience for lumbar spinal stenosis which is treated surgically.

Methods: In our study, 37 patients were included who were treated by transforaminal epidural steroid injection for Grade B lumbar spinal stenosis in our clinic between June-2014 and June-2018.

Epidural hemostasis by autologous fat graft in minimally invasive surgery for lumbar spinal stenosis: In vivo experimental study.

Background: Epidural hemostasis needs to use small, adapted material in minimally invasive surgery, including bilateral decompression via a unilateral approach for lumbar spinal stenosis. Most surgeons avoid external material for hemostasis because of possible neural tissue damage or complications. We compared epidural hemostasis in minimally invasive surgery by fat graft versus gelatin sponge.

Aim: To describe the ultrasound-guided microsurgical excision technique and to evaluate the surgical outcomes of brachial plexus schwannomas.

Material And Methods: Eleven patients who underwent ultrasound-guided microsurgery for small ( < 3 cm) brachial plexus schwannomas between 2013 and 2017 were included in our study.

Results: The mean age of the patients was 45 years (range: 30-68 years), with six tumors localized on the right and five on the left side.

Surgical outcome and efficacy of lumbar microdiscectomy technique with preserving of ligamentum flavum for recurrent lumbar disc herniations.

The reoperation for recurrent lumbar disc herniation (LDH) causes difficulties and low surgical outcome. The operation technique which was preferred in the first surgery has gained importance in reoperation for recurrent-LDH. The aim of our study is to evaluate the efficacy of lumbar microdiscectomy technique with preserving of ligamentum flavum (LF) for recurrent lumbar disc surgery.

Long-Term Clinical Outcome and Reoperation Rate for Microsurgical Bilateral Decompression via Unilateral Approach of Lumbar Spinal Stenosis.

Objective: To evaluate long-term outcome and reoperation rate for microsurgical bilateral decompression via unilateral approach of lumbar spinal stenosis, a common degenerative spinal disease of the lumbar spine.

Methods: In this observational prospective study, 918 patients were treated for single-level or multilevel lumbar spinal stenosis by bilateral decompression via unilateral approach between January 2002 and January 2016. Of 918 patients, 180 underwent microdiscectomy with decompression.

Midterm outcome of thoracic disc herniations that were treated by microdiscectomy with bilateral decompression via unilateral approach.

Thoracic disc herniation (TDH) surgery carries risks of neurological worsening due to thoracic cord retraction injury. Multiple approaches have been developed aiming for resecting the disc herniations of the thoracic segment. We have conducted a prospective observational study to evaluate the mid-term outcome of thoracic microdiscectomy with bilateral decompression via a unilateral approach (BDUA).

A Prospective Study of Interbody Fat Graft Application With the Anterior Contralateral Cervical Microdiscectomy to Preserve Segmental Mobility.

Background: Any surgical procedure aims at protecting mobile segments at the operated level, and the sagittal balance of the columna vertebralis. Interbody fusion has become an often applied technique in anterior cervical discectomy.

Objective: To indicate that a minimally invasive technique in which we use interbody fat graft placement showed great results and effectiveness, especially in patients who were suffering from cervical paramedian disc herniation.

An extremely rare appendiceal anomaly: horseshoe appendicitis.

Appendiceal anomalies are extremely rare malformations that are usually found in adult populations as an incidental finding. Agenesis and duplication of the appendix have been well documented, but we know of only three reported cases of a horseshoe appendix. A 64-year-old woman admitted to the emergency department.

Clip ligation of unruptured intracranial aneurysms: a prospective midterm outcome study.

Background: We conducted a prospective study to investigate the clinical and radiological outcome in a surgical case series of 176 patients with 203 unruptured intracranial aneurysms (UIA).

Methods: The success of aneurysm obliteration was assessed within 2 weeks after surgery by digital subtraction angiography (DSA). Patients also underwent angiography 5 years after surgery.

Unilateral frontal interhemispheric transfalcial approaches for the removal of olfactory groove meninjiomas.

Aim: A unilateral subfrontal interhemispheric transfalcial approach for the removal of olfactory groove meningiomas (OGM) was evaluated in terms of surgical technique, complications, clinical outcomes, and recurrence rate.

Transsellar transsphenoidal rhino-oral encephalocele.

Transsphenoidal encephaloceles are rare and the transsellar variety is the least common. We present a 1-year-old male patient with transsellar transsphenoidal encephalocele which herniated into the oral cavity through the congenital split palate. The patient was operated on using a combined transcranial and transpalatal approach without mortality or permanent morbidity.

Spinal cord compression caused by a brown tumor at the cervicothoracic junction.

Background Context: Brown tumors are classic benign skeletal manifestations of hyperparathyroidism, but the spine involvement is very rare. Spinal reconstruction in these patients is controversial because of the severe osteoporosis and impaired bone healing. Of the reported 12 cases of spinal brown tumors in the literature, only in 5 were reconstructions with bone graft used.
