Backgroud: Intervertebral disc herniations are caused by rupture of the fibrous ring and migration of one part of the nucleus pulposus towards the spinal canal. The most commonly affected levels are C5-C6 and C6-C7. Surgical treatment of cervicobrachialgia is indicated in the presence of long-term intense pain syndrome with or without radicular sensory-motor deficit and magnetic resonance (MRI) verified disc herniation with a compressive effect. Objective: The most common surgical treatment is anterior lateral microdiscectomy with or without the use of implants. In addition to this method, dorsolateral microsurgical treatment can be used for foraminal hernias. Methods: This retrospective study included 110 (58 / 52.7% male and 52 / 47.3% female) patients with cervical disc herniations who were surgically treated at the Neurosurgery clinic of Clinical Center of Sarajevo University (CCUS) in a five-year period. Stability, postoperative curvature, arthrodesis, implants, and changes in adjacent segments were radiographically analyzed. In the outcome assessment, functional outcome and patient satisfaction were analyzed using the Pain Self-Evaluation Scale (VAS), Prolo functional and economic score, and White’s classification of treatment outcomes. Results: The dominant prevalence of changes was recorded at the levels of C5-C6 (58%) and C4-C5 (28%) with a ventrolateral approach performed in 90% of patients. The largest representation is hard dorsolateral discs (n = 77). In the group of patients with placed implant, hard discs were present in 96 (90%) cases (p <0.001), while soft discs were dominant in patients without implant placement (p <0.001). In the group of subjects with implant, the most common are hard dorsolateral discs and those of mixed localization in 41 of 55 patients (65.5%; p = 0.001). The most common implant is PEEK cage (74.5%). From complications, we had partial vertebral body fractures in 4.5% of patients. Furtehr, the most common are sensory disturbances in 2.73% of respondents. Reduction of symptoms and improvement of preoperative neurological status were observed in over 95% of patients. Conclusion: Surgical treatment of cervical disc herniation is a safe method with a minimal percentage of complications. Microsurgical discectomy significantly contributes to the improvement of the functional status of patients, the reduction of pain, and the improvement of neurological deficit and overall mobility.

Glioma surgery has been the main component of glioma treatment for decades. The surgi- cal approach changed over time, making it more complex and more challenging. With molecular knowledge and diagnostic improvement, this challenge became maximally safe resection of tumor, which resulted in prolonged overall survival, progression-free period, and a better quality of life. Today, the standard glioma treatment includes maximally safe resection, if feasible, administration of temozolomide, radiotherapy, and chemotherapy. Surgical resection is performed as subtotal resection, gross total resection, and supratotal resection. Subtotal resection is the resection where a part of tumor is left. Gross total resection is a complete removal of the magnetic resonance imaging (MRI) visible tumor tissue. Supratotal resection is performed as gross total resection with excising the MRI visible tumor tissue borders into the unaffected brain tissue. Before we make final decision on which type of resection should be performed, many factors have to be considered. The question has to be answered: what the actual impact of resection on the progression of glioma is and what the functional risk of resection is.
