In-house 3D modeling associated with margin-negative resection in mandibular oral cavity malignancies.

Objective: To evaluate whether the intraoperative use of patient specific 3D printed models is associated with better surgical margin outcomes for T4 oral cavity squamous cell carcinoma resection.

Patients And Methods: A retrospective cohort study ofpatients from a single, tertiary care center diagnosed with T4 squamous cell carcinoma of the oral cavity and underwent segmental mandibulectomy between January 2021 and October 2023. Subjects were split into those who received an in-house 3D model for intraoperative use and a control group that did not receive a model or other commercial virtual planning.

Mandibular reconstruction outcomes for in-house patient-specific solutions.

Background: Segmental mandibulectomy and mandibular reconstruction are often performed for various benign and malignant head and neck conditions. Standard of care reconstruction involves titanium plate fixation with tissue transfer. The advent of computer-aided design and manufacturing (CAD/CAM) has enhanced aesthetic and functional outcomes in mandibular reconstruction by enabling patient-specific solutions like 3D-printed anatomic models.

Multi-Site evaluation of a novel point-of-care 3D printing quality assurance protocol for a material jetting 3D printer.

Background: The maturation of 3D printing technologies has opened up a new space for patient advancements in healthcare from trainee education to patient specific medical devices. Point-of-care (POC) manufacturing, where model production is done on-site, includes multiple benefits such as enhanced communication, reduced lead time, and lower costs. However, the small scale of many POC manufacturing operations complicates their ability to establish quality assurance practices.

Impact of obesity on adult spinal deformity (ASD) long-segment spinal fusion radiographic and clinical outcomes.

Study Design: Retrospective chart review of patients receiving long-segment fusion during a five-year period.

Objective: To determine whether obese patients receive comparable benefits when receiving long-segment fusion compared to non-obese patients and to identify factors that may predict hardware failure and post-surgical complications among obese patients.

Methods: Demographic, spinopelvic radiographic, patient-reported outcome measures (PROMs), and complications data was retrospectively collected from 120 patients who underwent long-segment fusion during a five-year period at one tertiary care medical center.

The infundibulochiasmatic angle and the favorability of an endoscopic endonasal approach in type IV craniopharyngioma: illustrative case.

Background: Lesions located in the floor of the third ventricle are among the most difficult to access in neurosurgery. The neurovascular structures can limit transcranial exposure, whereas tumor extension into the third ventricle can limit visualization and access. The midline transsphenoidal route is an alternative approach to tumor invading the third ventricle if the tumor is localized at its anterior half and a working space between the optic apparatus and the pituitary infundibulum exists.

A Mixed-Methods Needs Assessment for a Longitudinal Surgical Preparation Course in Undergraduate Medical Education.

Objective: To assess the unmet needs associated with surgical education and skill development during the pre-clerkship years of medical school.

Design: A mixed-methods design was employed that leveraged semi-structured interviews and quantitative surveys followed by qualitative analysis.

Setting: A large midwestern academic medical center.
