Presenting characteristics and clinical outcomes of idiopathic versus neurofibromatosis type 2-associated spinal meningiomas: a retrospective institutional experience.

Objective: Spinal meningioma (SM) is a pathology with an estimated incidence of nearly 1000 diagnoses per year in the United States and presents in 20% of patients with neurofibromatosis type 2 (NF2). This multi-institutional retrospective cohort study aimed to assess clinical outcomes for patients with SM who underwent surgery between 1998 and 2020 with stratification by NF2 mutation status.

Methods: Medical records were reviewed retrospectively to collect data on patient demographics, clinical presentation, tumor characteristics, treatment, and outcomes.

Teaching Application of 3D-printed Models for Nasal Analysis.

Background: A major challenge in learning rhinoplasty is correlating patients' external and internal nasal structures. We aim to explore the application of three dimensional (3D)-printed models of nasal bony-cartilaginous structures in identifying accurate nasal anatomy.

Methods: Otolaryngology-head and neck surgery and plastic and reconstructive surgery residents matched patient photograph models, described relative nasal bony-cartilaginous anatomy, completed pre- and postactivity self-evaluations (based on otolaryngology "nasal deformity" milestones including "anatomy," "function," "aesthetic," and "etiology"), and rated the 3D-printed models' usefulness.

This systematic review and meta-analysis endeavors to elucidate the multifactorial dimensions and clinical significance of cervical MCs.

Methods: Following PRISMA guidelines, a comprehensive systematic search was performed using Medline (via PubMed), EMBASE, Scopus, and Web of Science databases from their dates of inceptions to September 4, 2023.

The Importance of Planning Ahead: A Three-Dimensional Analysis of the Novel Trans-Facet Corridor for Posterior Lumbar Interbody Fusion Using Segmentation Technology.

Background: The rise of minimally invasive lumbar fusions and advanced imaging technologies has facilitated the introduction of novel surgical techniques with the trans-facet approach being one of the newest additions. We aimed to quantify any pathology-driven anatomic changes to the trans-facet corridor, which could thereby alter the ideal laterality of approach to the disc space.

Methods: In this retrospective cohort study, we measured the areas and maximum permissible cannula diameters of the trans-facet corridor using commercially available software (BrainLab, Munich, Germany).

Lumbar Facet Arthroplasty Versus Fusion for Grade-I Degenerative Spondylolisthesis with Stenosis: A Prospective Randomized Controlled Trial.

Background: The comparative effectiveness of decompression plus lumbar facet arthroplasty versus decompression plus instrumented lumbar spinal fusion in patients with lumbar spinal stenosis and grade-I degenerative spondylolisthesis is unknown.

Methods: In this randomized, controlled, Food and Drug Administration Investigational Device Exemption trial, we assigned patients who had single-level lumbar spinal stenosis and grade-I degenerative spondylolisthesis to undergo decompression plus lumbar facet arthroplasty (arthroplasty group) or decompression plus fusion (fusion group). The primary outcome was a predetermined composite clinical success score.

Evolution of the Transforaminal Lumbar Interbody Fusion (TLIF): From Open to Percutaneous to Patient-Specific.

The transforaminal lumbar interbody fusion (TLIF) has seen significant evolution since its early inception, reflecting advancements in surgical techniques, patient safety, and outcomes. Originally described as an improvement over the posterior lumbar interbody fusion (PLIF), the TLIF began as an open surgical procedure, that notably reduced the need for the extensive neural retractation that hindered the PLIF. In line with the broader practice of surgery, trending toward minimally invasive access, the TLIF was followed by the development of the minimally invasive TLIF (MIS-TLIF), a technique that further decreased tissue trauma and postoperative complications.

Catheter Tip-Associated Mass With Continuous Infusion of Sufentanil for Persistent Spinal Pain Syndrome Type 2: A Case Report Including Histopathologic Examination and Review of the Associated Basic and Clinical Research.

Objectives: Intrathecal opioids delivered by implanted pumps are used to treat malignant or nonmalignant chronic pain. In this study, we 1) review a case in which intrathecal infusions of sufentanil along with other adjuvants were used and after an extended period led to an intrathecal mass and 2) compared and contrasted the potential mechanisms for these phenomena.

Materials And Methods: A woman aged 66 years with a history of scoliosis and multiple spine surgeries was treated with an implantable drug delivery system for treating persistent pain after laminectomy.

Using Novel Segmentation Technology to Define Safe Corridors for Minimally Invasive Posterior Lumbar Interbody Fusion.

Background And Objectives: There has been a rise in minimally invasive methods to access the intervertebral disk space posteriorly given their decreased tissue destruction, lower blood loss, and earlier return to work. Two such options include the percutaneous lumbar interbody fusion through the Kambin triangle and the endoscopic transfacet approach. However, without accurate preoperative visualization, these approaches carry risks of damaging surrounding structures, especially the nerve roots.

Shared Decision-Making in Patients Seeking Surgery for Facial Trauma: The Role of Decisional Conflict and Perceived Discrimination.

Shared decision-making (SDM) may facilitate challenging discussions between patients with facial trauma and reconstructive surgeons. To determine among patients seeking surgical evaluation for facial trauma, whether patient demographics, decisional conflict (DC), or experiences of discrimination in health care are associated with patient perceptions of SDM, as measured by scored responses on the CollaboRATE-10 questionnaire. English-speaking adults who presented to the offices of five facial trauma surgeons were contacted by telephone after their visit to complete a cross-sectional survey.

Geriatric Surgery Produces a Hypoactive Molecular Phenotype in the Monocyte Immune Gene Transcriptome.

Surgery is a major challenge for the immune system, but little is known about the immune response of geriatric patients to surgery. We therefore investigated the impact of surgery on the molecular signature of circulating CD14 monocytes, cells implicated in clinical recovery from surgery, in older patients. We enrolled older patients having elective joint replacement (N = 19) or spine (N = 16) surgery and investigated pre- to postoperative expression changes in 784 immune-related genes in monocytes.

Genomic analysis of spinal meningiomas: correlation with histopathological grade.

Objective: Spinal meningiomas are one of the most common primary intradural tumors of the adult spine. Spinal meningiomas typically have a benign course with low rates of recurrence. Recent advances in genomic profiling have provided valuable information on meningioma biology and natural history, but these studies have focused primarily on cranial meningiomas.

Two-Year Clinical and Radiographic Outcomes for Percutaneous Lumbar Interbody Fusion With an Expandable Titanium Cage Through Kambin's Triangle Without Facetectomy.

Background: There has been heightened interest in performing percutaneous lumbar interbody fusions (percLIFs) through Kambin's triangle, an anatomic corridor allowing entrance into the disc space. However, due to its novelty, there are limited data regarding the long-term benefits of this procedure. Our objective was to determine the long-term efficacy and durability of the percutaneous insertion of an expandable titanium cage through Kambin's triangle without facetectomy.

Novel Approach to Percutaneous Lumbar Surgeries via Kambin's Triangle-Radiographic and Surgical Planning Analysis with Nerve Segmentation Technology.

Objective: While Kambin's Triangle has become an ever more important anatomic window given its proximity to the exiting nerve root, there have been limited studies examining the effect of disease on the corridor. Our goal was to better understand how pathology can affect Kambin's Triangle, thereby altering the laterality of approach for percutaneous lumbar interbody fusion (percLIF).

Methods: The authors performed a single-center retrospective review of patients evaluated for percLIF.

Patient-Reported Outcomes Measures in Rhinoplasty: Need for Use and Implementation.

Patient-reported outcome metrics (PROMs) are increasingly utilized to capture data about patients' quality of life. PROMs play an important role in the value-based health care movement by providing a patient-centered metric of quality. There are many barriers to the implementation of PROMs, and widespread adoption requires buy-in from numerous stakeholders including patients, clinicians, institutions, and payers.

Mastering Midface Injections.

Injectable filler is one of the most common cosmetic procedures performed annually. An aging face shows a characteristic loss of volume in the deep fat pads of the midface. The goal of midfacial rejuvenation with injectable filler is to restore lost volume, with the suborbicularis fat pad and deep medial cheek fat being the most critical areas.

A Contemporary Review of the Role of Facial Prostheses in Complex Facial Reconstruction.

Background: Maxillofacial prostheses provide effective rehabilitation of complex facial defects as alternatives to surgical reconstruction. Although facial prostheses provide aesthetically pleasing reconstructions, multiple barriers exist that prevent their routine clinical use. The accessibility of facial prostheses is limited by the scarce supply of maxillofacial prosthodontists, significant time commitment and number of clinic appointments required of patients during prosthesis fabrication, short lifespan of prostheses, and limited outcomes data.

Evidence-Based Medicine for Mandible Fracture Repair: Current Controversies and Future Opportunities.

Mandibular fractures are among the most common facial fractures resulting from trauma. The nature of the injury, involved facial structures, presence of associated injuries, the dental status of the patient, comorbid conditions, and psychosocial context all must be considered by the surgeon when planning the optimal treatment for these patients. While consensus exists for many aspects of the management of mandibular trauma, some elements remain controversial.

Gross total resection of spinal chondrosarcoma is associated with improved locoregional relapse-free survival and overall survival.

Background: Spinal chondrosarcomas are rare malignant osseous tumors. The low incidence of spinal chondrosarcomas and the complexity of spine anatomy have led to heterogeneous treatment strategies with varying curative and survival rates. The goal of this study is to investigate prognostic factors for locoregional recurrence-free survival (LRFS) and overall survival (OS) comparing en bloc vs.

Facial Trauma Operative Volume Demonstrates Consistent and Significant Yearly Periodicity.

Purpose: Facial trauma requiring operative care increases during the summer and fall months, which is colloquially referred to as trauma season. The purpose of this study is to determine if there is a quantifiable and statistically significant yearly periodicity of operative facial trauma volume.

Materials And Methods: To confirm the existence and quantify the magnitude of trauma season, we conducted a retrospective cohort study.
