Management of traumatic laryngotracheal separation: Case series and review.

Laryngotracheal separation injuries are a rare but serious condition, as survival from such injuries relies on proper airway management. As a result, recommendations for management have been based on small case reports and expert opinion. We reviewed our last 10 years of experience with managing laryngotracheal separation injuries and identified 6 cases for chart review.

Transoral robotic submandibular gland transposition to reconstruct radical tonsillar resection defects.

Significant dysphagia, pain, and risk of bleeding occur after transoral robotic surgery (TORS) radical tonsillectomy. We present a novel surgical technique utilizing robotically assisted submandibular gland transposition (SMGT) to reconstruct the radical tonsillar defect. A 48-year-old male with p16+ tonsillar squamous cell carcinoma underwent deep TORS radical tonsillectomy, contralateral tonsillectomy, ipsilateral neck dissection, and TORS-assisted reconstruction of the radical defect with ipsilateral SMGT.

A Case of a Nonpetrous Cholesterol Granuloma Presenting as a Temporal Mass.

Objective: A case of a skull base cholesterol granuloma (CG) of the squamosal temporal bone. This is the first ever reported case of CG in a well-pneumatized squamous temporal bone.

Design: Case report and review of the literature.

Sound levels with aural suctioning: Effects of suction size, canal moisture, and distance from the eardrum.

Objective: To determine sound levels resulting from aural suctioning of the external auditory canal.

Methods: Unweighted decibels (dB) and A-weighted decibels (dBA) sound pressure level measurements were recorded using a retrotympanic microphone in cadaveric human temporal bones. Sound measurements were made with common otologic suctions, size 3, 5, and 7 French, within the external ear canal at the tympanic membrane, 5, and 10 mm from the tympanic membrane in the dry condition.

Posttraumatic Cranial Suture Diastasis in Pediatric Temporal Bone Fractures.

Objective: Only a handful of case reports exist describing posttraumatic sutural diastasis in the calvarium and none report concurrent temporal bone involvement. We aim to describe diastasis along the temporal bone suture lines in the setting of temporal bone trauma and to identify clinical sequelae.

Study Design: Retrospective case review.

Possible Skull Base Erosion After Prolonged Frontal Sinus Stenting.

Frontal sinus stenting is widely used with the goal of maintaining nasofrontal duct patency after sinus surgery. The general recommendation is to leave stents in place for 6 months; however, prolonged stenting up to 6 years has been reported with no complication. We present the first reported case of frontal sinus posterior table and skull base erosion following prolonged frontal sinus stenting.

The Plication Technique to Enhance the Endoscopic Approach to Zenker's Diverticulum.

Endoscopic stapler approaches to Zenker's diverticulum often yield a persistent diverticulum and recurrent dysphagia up to 20%. A novel technique to reduce the postoperative diverticulum is described. Eight consecutive patients with Zenker's diverticulum who underwent endoscopic stapler diverticulotomy had adjunctive endoscopic plication of the diverticulum wall to functionally reduce the residual diverticulum size.

Discrepancy Between Neurosurgery Morbidity and Mortality Conference Discussions and Hospital Quality Metric Standards.

Objective: Medical institutions use quality metrics to track complications seen in hospital admissions. Similarly, morbidity and mortality (M&M) conferences are held to peer review complications. The purpose of this study was to compare the complications identified in a cohort of patients within 30 days of neurosurgical intervention with those captured in a cohort of M&M conferences.

A novel technique for unilateral supraglottoplasty.

Objectives: Traditional supraglottoplasty for pediatric laryngomalacia is most commonly conducted with either CO2 laser or cold steel instruments. While the procedure enjoys high success rates, serious complications such as excessive bleeding, supraglottic stenosis and aspiration can occur. Unilateral coblation supraglottoplasty may reduce this risk, but data on respiratory and swallowing outcomes are lacking.

Identification of shikimate kinase inhibitors among anti-Mycobacterium tuberculosis compounds by LC-MS.

Increasing drug resistance has challenged the control and treatment of tuberculosis, sparking recent interest in finding new antitubercular agents with different chemical scaffolds and mechanisms of action. Mycobacterium tuberculosis shikimate kinase (MtSK), an enzyme present in the shikimate pathway in bacteria, is essential for the survival of the tubercle bacillus, representing an ideal target for therapeutic intervention given its absence in mammals. In this study, a small library of 404 synthetic antimycobacterial compounds identified and supplied through the NIH Tuberculosis Antimicrobial Acquisition and Coordinating Facility (TAACF) high throughput screening program against whole cell M.
