Endoscopic Endonasal Occipitocervical Fixation with a Customized Three-Dimensional Printed Titanium Plate-Screw Construct: A Cadaveric Feasibility Study.

Objective: To evaluate the feasibility of a novel method for occipitocervical fixation (OCF) through the endonasal corridor.

Methods: Thin-cut computed tomography scans were obtained for 5 cadaveric specimens. Image segmentation was used to reconstruct 3D models of each O-C1 joint complex.

2D versus 3D Endoscopy: Head-to-Head Comparison in a Simulated Model of Endoscopic Endonasal Dural Suturing.

 Endonasal dural suturing (EDS) has been reported to decrease the incidence of cerebrospinal fluid fistula. This technique requires handling of single-shaft instrumentation in the narrow endonasal corridor. It has been proposed that three-dimensional (3D) endoscopes were associated with improved depth perception.

Does the History of Tracheoesophageal Fistula Repair Alter Outcomes of Laryngeal Cleft Repair?

Objective: Tracheoesophageal fistula and esophageal atresia (TEA) and laryngeal cleft (LC) can coexist in some patients. The surgery-specific success rate of LC repair in children with associated TEA has not been well described. The aim of the study is to determine if the history of TEA alters the LC repair outcomes.

Roadmap to Ventral Craniocervical Junction Through the Endonasal Corridor: Anatomic Evaluation of Inverted U-Shaped Nasopharyngeal Flap Exposure in a Cadaveric Study.

Background: There is a paucity of data in the literature describing quantitative exposure of the ventral craniocervical junction through the endonasal corridor in a safe manner mindful of locoregional anatomy.

Objective: To quantify ventromedial exposure of O-C1 and C1-2 articular structures after turning an inverted U-shaped nasopharyngeal flap (IUNF) and to obtain measurements assessing the distance of flap margins to adjacent neurovascular structures.

Methods: In 8 cadaveric specimens, an IUNF was fashioned using a superior incision below the level of the pharyngeal tubercule of the clivus and lateral incisions in the approximate region of Rosenmuller fossae bilaterally.

Peritonsillar Abscess Simulator: A Low-Cost, High-Fidelity Trainer.

Audience: Our reusable low-cost peritonsillar abscess simulator (PTA) simulator is designed to train emergency medicine (EM) residents, fellows, and medical students. Trainees who are interested in otolaryngology (OTL) or this specific disease may also benefit from this simulator.

Introduction: Peritonsillar abscess is one of the most common deep infections 1 of the head and neck, accounting for 7589 consultations and 11069 hospital bed days in the UK between 2009-2010.

Establishing an Endoscopic Chronic Subglottic Stenosis Rabbit Model.

Objectives/hypothesis: To develop a reproducible and consistent chronic subglottic stenosis (SGS) in an endoscopic animal model.

Study Design: Prospective study.

Methods: We conducted a prospective study using New Zealand white rabbits.

Electrospinning of cyanoacrylate tissue adhesives for human dural repair in endonasal surgery.

Cerebral spinal fluid (CSF) leakage is a major postoperative complication requiring surgical intervention, resulting in prolonged healing and higher costs. Biocompatible polymers, such as cyanoacrylates, are currently used as tissue adhesives for closing surgical defects and incisions. Coupling these polymers with nanofiber technology shows promising results for generating nanofibers used in wound care, tissue engineering, and drug delivery.

Primary Dural Repair via an Endoscopic Endonasal Corridor: Preliminary Development of a 3D-Printed Model for Training.

 Endonasal suturing is an investigational method for dural repair that has been reported to decrease the incidence of cerebrospinal fluid fistula. This method requires handling of single-shaft instrumentation in the narrow endonasal corridor. In this study, we designed a low-cost, surgical model using three-dimensional (3D) printing technology to simulate dural repair through the endonasal corridor and subsequently assess the utility of the model for surgical training.

Risk of Infection Associated with Transmucosal Placement of Instrumentation in Clean-Contaminated Field: Systematic Analysis.

Instability of the craniovertebral junction (CVJ) following odontoidectomy is relatively common. Traditionally, separate stage posterior atlantoaxial ± occipitocervical fusion is used for treatment. A transmucosal approach using a clean-contaminated route is associated with hypothetical risks of infectious complications.

Rhinogenic headache in pediatric and adolescent patients: an evidence-based review.

Background: Although some causes of rhinogenic headache, such as acute sinusitis, have clear diagnostic criteria, others, such as "sinus headache" and mucosal contact points, are more nebulous. Misdiagnosis of these entities and primary headaches may result in unnecessary medical or surgical treatment. The purpose of this systematic review is to delineate current understanding of diagnosis and treatment of rhinogenic headaches, including sinus and mucosal contact point headaches, in children.
