 The middle fossa craniotomy (MFCs) is commonly utilized for spontaneous cerebrospinal fluid (CSF) leaks, encephaloceles, and superior semicircular canal dehiscence (SSCD). This study compares postoperative outcomes of MFCs with and without LD use.  A retrospective cohort study of adults over the age of 18 years presenting for the repair of nonneoplastic CSF leak, encephalocele, or SSCD via MFC from 2009 to 2021 was conducted.

Introduction: Repeat sport-related concussion (SRC) is anecdotally associated with prolonged recovery. Few studies have examined repeat concussion within the same athlete. We sought to explore differences in symptom burden and recovery outcomes in an individual athlete's initial and repeat SRC.

Objective: Cerebrospinal fluid shunt placement is associated with high rates of infection. Multiple standardized protocols, particularly in pediatric populations, have been proposed to mitigate this infection rate. We sought to determine the effectiveness of a standardized shunt infection protocol in a large adult population.

Introduction: Pediatric craniopharyngioma is a complex pathology, with optimal management involving a multidisciplinary approach and thoughtful care coordination. To date, no studies have compared various treatment modalities and outcomes described in different global regions. We conducted a comprehensive systematic review to compare demographics, clinical presentation, treatment approach and outcomes of children diagnosed with craniopharyngioma globally.

Article Synopsis
  • The study investigates the lack of research on race and ethnicity in sport-related concussions (SRC) among youth athletes, recognizing it as an important public health issue.
  • A systematic review of 4,583 studies resulted in 854 articles being included, with only 15.5% reporting race and 7.6% reporting ethnicity, indicating a significant gap in data collection.
  • The findings suggest that most studies reported race solely as a demographic descriptor rather than as a significant variable, highlighting the need for improved reporting practices in SRC research.

Objective: Accurately predicting early (≤ 14 days) versus typical (15-27 days) or delayed (≥ 28 days) recovery from sport-related concussion (SRC) may allow for improved resource utilization and precision in planning and carrying out rehabilitation. In this study, the authors sought to develop an algorithm that enables accurate differentiation of recovery periods and duration after SRC. The authors hypothesized that data regarding initial symptom burden as quantified by a Post-Concussion Symptom Scale (PCSS) score, time to presentation, and number of prior concussions would be the most useful for analyzing predictive factors for concussion recovery duration.

Objective: Following sport-related concussion (SRC), early studies have demonstrated racial differences in time to clinical recovery; however, these differences have not been fully explained. We sought to further explore these associations by considering possible mediating/moderating factors.

Methods: Data from patients aged 12-18 years diagnosed with SRC from November 2017 to October 2020 were analyzed.

Introduction: Meningiomas have varying degrees of aggressive behavior. Some systemic hematologic makers are associated with malignancy, but their value in predicting aggressive meningioma behavior is not fully understood.

Objective: To evaluate the association between preoperative markers such as neutrophil-lymphocyte ratio (NLR), neutrophil-monocyte ratio (NMR), monocyte-lymphocyte ratio (MLR), platelet-lymphocyte ratio (PLR), and prognostic nutritional index (PNI), and diagnostic and prognostic factors including WHO grade, proliferation index, presence of edema on preoperative MRI, and tumor recurrence.

Background: Recurrence after meningioma resection warrants serial surveillance imaging, but little evidence guides the optimal time interval between imaging studies/surveillance duration.

Objective: To describe recurrence-free survival (RFS) after meningioma resection, conditioned to short-term RFS.

Methods: A retrospective cohort study for adults presenting for meningioma resection from 2000 to 2018 was conducted.

Introduction: Posterior cervical spine approaches have been associated with increased rates of wound complications compared to anterior approaches. While barbed suture wound closure for lumbar spine surgery has been shown to be safe and efficacious, there is no literature regarding its use in posterior cervical spine surgery. In a cohort of patients undergoing elective posterior cervical spine surgery, we sought to compare postoperative complication rates between barbed and traditional interrupted suture closure.

Background: Two common approaches for open, one-level, posterior lumbar fusions include transforaminal lumbar interbody fusion (TLIF) and posterolateral fusion (PLF) alone without an interbody.

Objective: To compare TLIF vs PLF alone in (1) discharge disposition, (2) return to work (RTW), and (3) patient-reported outcomes (PROs).

Methods: A single-center, retrospective cohort study was undertaken between October 2010 and May 2021, all with a 1-year follow-up and excluding patients with isthmic spondylolisthesis.

Purpose: The management of incidentally discovered meningioma remains controversial. We sought to compare outcomes following surgical resection of incidental meningioma to a matched cohort of symptomatic meningiomas.

Methods: A retrospective single-center case-control study was conducted for patients undergoing resection of incidental meningioma from 2000 to 2019.

Background: Neurofibromatosis type 1 (NF-1) is a neurocutaneous autosomal dominant disorder that predisposes patients to develop intracranial low-grade gliomas (LGGs). Most LGGs in patients with NF-1 involve the optic pathway but can arise anywhere throughout the central nervous system. NF-1-related disseminated pediatric LGG (dPLGG) in the absence of a dominant optic pathway glioma has not been described.

Introduction: Intrauterine myelomeningocele repair (IUMR) and postnatal myelomeningocele repair (PNMR) differ in terms of both setting and surgical technique. A simplified technique in IUMR, in which a dural onlay is used followed by skin closure, has been adopted at our institution. The goal of this study was to compare the rates of clinical tethering in IUMR and PNMR patients, as well as to evaluate the appearance on MRI.

Introduction: Cystic meningiomas are rare, accounting for 2-7% of all intracranial meningiomas. Little is known regarding whether these meningiomas behave differently compared to solid meningiomas. We sought to study this relatively uncommon imaging appearance of meningioma and to evaluate its clinical significance.

Article Synopsis
  • The study aimed to understand how initial cognitive symptoms from sport-related concussions affect the time it takes for adolescents to return to learning (RTL).
  • Researchers analyzed data from 346 adolescent athletes who were assessed shortly after their concussions, focusing on their cognitive symptom scores compared to overall symptoms.
  • Results indicated that higher cognitive symptom ratios were initially linked to longer RTL durations, but this connection faded when overall symptom severity was also considered; however, those with lower cognitive symptom ratios had a higher likelihood of returning to learning within a week.

Objective: Excision of intracranial meningiomas often requires resection or coagulation of the dura mater. The choice of dural closure technique is individualized and based on surgeon preference. The objective of this study was to determine outcomes following various dural closure techniques for supratentorial meningiomas.
