Aim: To investigate the outcomes of the simultaneous closure of bilateral cranial defects using custom-made three-dimensional (3D) titanium implants.

Material And Methods: Demographic data of 26 patients with bilateral cranial defects who underwent cranioplasty using the 3D custom-made titanium implants in our clinic between 2017 and 2022 were retrospectively reviewed. Data on the area of cranium defect, the time interval between last cranial surgery and cranioplasty, postoperative complications, etiology of the cranium defect, and hospitalization of the patient were statistically evaluated.

Resection of intra- and paraventricular malignant brain tumors using fluorescein sodium-guided neuroendoscopic transtubular approach.

Background: The requirement of brain retraction and difficulty in distinguishing the tumor demarcation are challenging in conventional approaches to intra- and paraventricular malignant tumors (IV-PVMTs). Tubular retractors can minimize the retraction injury, and fluorescein-guided (FG) surgery may promote the resection of tumors. Our aim is to evaluate the feasibility, safety, and effectiveness of fluorescein-guided endoscopic transtubular surgery for the resection of IV-PVMTs.

Endoscopic endonasal approach to the cavernous sinus Epstein-Barr virus-positive B cell non-Hodgkin lymphoma in a child: case report.

Cavernous sinus (CS) lymphoma without paranasal sinuses involvement is extremely rare in pediatric population and remains a diagnostic challenge due to its similarity to other tumors located in this area. An 8-year-old boy presented with a 6-day history of gradually developing ptosis in the right eyelid. After admission, his symptoms progressed within 24 h to include right-sided ophthalmoplegia consisting of oculomotor and abducens nerve palsies.

Fluorescein Sodium-Guided Neuroendoscopic Resection of Deep-Seated Malignant Brain Tumors: Preliminary Results of 18 Patients.

Material And Methods: A total of 13 patients underwent surgical resection of an intraaxial brain lesion larger than 3 cm with a fully endoscopic approach using the navigation-guided pediatric anoscope. The anoscope was adapted to serve as a tubular retractor.

Endoscope-Assisted Microsurgical Removal of an Intraventricular Ependymal Cyst That Manifested with Tremor.

Background: Intraventricular ependymal cysts (ECs) are rare, histologically benign neuroepithelial cysts. Most of these cysts are clinically silent and discovered incidentally. Rarely, they become symptomatic, leading to obstruction of the cerebrospinal fluid circulation.

The effects of different types of hair shaving on the body image and surgical site infection in elective cranial surgery.

Aims And Objectives: To investigate the effects of different types of shaving on body image and surgical site infection in elective cranial surgery.

Background: Hair shaving before cranial surgery is commonly performed in many countries. However, the impact of shaving on the patients' body image and surgical site infection is not, as yet, well investigated.

Evaluation and Management of Lumbosacral Myelomeningoceles in Children.

Objective: Myelomeningoceles are the common form of open neural tube defects that are usually associated with neurological deficits. Many techniques of repair and methods of prevention have been proposed with respect to the size of defect and the neurological condition of patient. The aim of this study was to report our experience on the management of lumbosacral myelomeningoceles in children.

Computer-based surgical planning and custom-made titanium implants for cranial fibrous dysplasia.

Background: The procedure of reconstruction after the removal of cranial fibrous dysplasia (FD) must be precise to achieve good functional and aesthetic results. Intraoperative modeling of implants is difficult and may cause cosmetic disturbances.

Objective: To present our experience with the treatment of cranial FD using preoperative computer-based surgical planning of tumor removal with reconstruction of the cranium with custom-made titanium implants.

Surgical strategies for the removal of sphenoorbital meningiomas.

Central nervous system involvement of T-cell prolymphocytic leukemia diagnosed with stereotactic brain biopsy: case report.

Prolymphocytic leukemia (PLL) is a generalized malignancy of the lymphoid tissue characterized by the accumulation of monoclonal lymphocytes, usually of B cell type. Involvement of the central nervous system (CNS) is an extremely rare complication of T-cell prolymphocytic leukemia (T-PLL). We describe a case of T-PLL presenting with symptomatic infiltration of the brain that was histopathologically proven by stereotactic brain biopsy.

The use of a simple self-retaining retractor in the endoscopic endonasal transsphenoidal approach to the pituitary macroadenomas: technical note.

Background: During tumor removal in the endoscopic endonasal approach to pituitary adenomas with a significant suprasellar extension, the early descent of diaphragma sellae obscuring the visualization of the surgical field is a surgical challenge.

Objective: To describe a simple diaphragma retraction technique to eliminate this problem.

Methods: A transparent flexible material (a strip of polypropylene) was used as a self-retaining retractor to elevate the redundant diaphragma and to maintain the diaphragma elevation.

Concomitant tubercular and fungal cerebellar abscess in an immunocompromised girl.

Can scintigraphy explain prolonged postoperative neck pain?

Aim: Anterior cervical fusion procedures are among the most commonly performed spinal operations. Investigators have reported pseudoarthrosis rates ranging from 3 to 36% following anterior cervical fusion operations. The diagnosis of pseudoarthrosis has been based on the triad of pain, radiographic evidence of instability, and loss of correction or fixation.
