Background: Retromastoid craniectomy (RSC) is a cardinal surgical approach used to access the posterior fossa. Hydroxyapetite bone cement (HBC) is frequently employed for cranioplasty in efforts to prevent cerebrospinal fluid (CSF) leak, whilst maintaining low complication rates and good cosmetic satisfaction. The authors aim to determine the safety and effectiveness of HBC for reconstruction RSC used for treatment of various cranial nerves disorders.
Methods: The authors conducted a retrospective one-center two surgeons review of 113 patients who underwent RSC filled with HBC for the treatment of cranial nerve disorders. The study period extended from January 2011 through April 2016. Charts were reviewed for documentation of descriptors pertinent to the endpoints described above. Revisions and reoperations were excluded from analysis.
Results: Ninety-three patients met the inclusion criteria; there was one case of postoperative pseudomeningocele, which was considered as CSF leak (1%), 3 (3,2%) superficial infections, and no deep infections. Cosmetic satisfaction was obtained in all but one case (98.9% satisfaction) and long-term incisional pain was problematic in 1 (1.1%) patient. Other complications (serous drainage, headache, ear pain) accounted for three cases (3.2%).
Conclusions: The application of HBC in the reconstruction of RSC for the treatment of cranial nerves disorders is an effective method, yielding good cosmetic results whilst eliminating CSF leak. Additionally, it is safe due to the lack of deep-seated wound infections with low incidence of chronic incisional pain.

Department of Biomedical Imaging and Image-Guided Therapy, Medical University of Vienna, Vienna, Austria.
Objective: To apply a network medicine-based approach to analyze the phenome of the prenatal fetal MRI and biometric findings in the Chiari II malformation (CM II) to detect specific patterns and co-occurrences.
Method: A single-center retrospective review of fetal MRI scans obtained in fetuses with CM II was performed. Co-occurrence analysis was utilized to generate a phenotypic comorbidity matrix and visualized by Gephi software.

With their close anatomical relationship, the temporomandibular joint (TMJ), mandibular ramus, skull base, ear, and infratemporal fossa make up a complex structure that may collectively be referred to as the 'TMJ and adjacent structures complex' (TASC). This study presents the neoplasms that may be encountered in the TASC region and their classification, which may be useful for the surgical treatment. Data of 1022 consecutive patients treated with resection of TASC neoplasms from May 2000 to October 2022 were reviewed.

Objective: This study aimed to assess postoperative intracranial pressure in patients with clinical and/or radiological features of idiopathic intracranial hypertension (IIH) undergoing endoscopic endonasal surgery for primary cerebrospinal fluid (CSF) leak repair.
Methods: Data was prospectively collected from 9 patients diagnosed with CSF nasal leaks who underwent corrective endonasal surgery between January 1, 2021, and October 31, 2022. Postoperative intracranial pressure was measured via lumbar puncture at least one month after surgery.
Development and Validation of a Neurosurgical Phantom for Simulating External Ventricular Drain Placement.

January 2025
Department of Neurosurgery, University Medical Centre Utrecht, Utrecht, The Netherlands.
This study aimed to develop and validate a cost-effective, customizable patient-specific phantom for simulating external ventricular drain placement, combining image segmentation, 3-D printing and molding techniques. Two variations of the phantom were created based on patient MRI data, integrating a realistic skin layer with anatomical landmarks, a 3-D printed skull, an agarose polysaccharide gel brain, and a ventricular cavity. To validate the phantom, 15 neurosurgeons, residents, and physician assistants performed 30 EVD placements.
