Background: This study compares the outcomes of osteocutaneous radial forearm free flap (OC-RFFF) and fibula free flap (FFF) reconstruction of mandibular osteoradionecrosis (ORN).

Methods: Retrospective review of patients undergoing OC-RFFF/FFF reconstruction for mandible ORN between 2005 and 2020 at a tertiary center. Patient characteristics, postoperative complications, and functional outcomes were evaluated using chi-squared and logistic regression analysis.

Study Design: Retrospective cohort study.

Objective: The purpose of this study is to evaluate the impact of the COVID-19 global pandemic on the regional trends in facial trauma at a tertiary care, level 1 trauma center in Central New York.

Methods: The study sample was derived from the population of patients who presented with facial trauma to the emergency department at the Downtown and/or Community Campuses of SUNY Upstate University Hospital between March 1, 2020, and May 15, 2020, and compared to two historical controls in 2018 and 2019.

Study Design: Retrospective case series review.

Objective: Participation in athletics is common in high school and college students and presents an increased risk of injury in this age-group. Previous studies have included National Collegiate Athletic Association athletes but not high school athletes.

Importance: Venous thromboembolism (VTE) is associated with substantial morbidity and is the most common factor associated with preventable death among hospitalized patients. Data from otolaryngologic studies suggest that the risk of VTE may be underestimated among high-risk patients, particularly among those undergoing oncologic procedures. The incorporation of prolonged-duration chemoprophylaxis (PDC) into preventive therapy has been associated with substantial decreases in VTE incidence among patients undergoing oncologic surgery.

Objective: Partial intracapsular tonsillectomy (PIT) is a well-established technique for reducing post-operative morbidity in pediatric patients with sleep disordered breathing (SDB). Although tonsillar re-growth rates are reported as low, risks of symptom recurrence or need for completion tonsillectomy are clear disadvantages when compared to traditional tonsillectomy (TT). We aim to identify cohort differences to better guide clinical decision making and identify patient-specific factors that may influence this decision.

Objective: This review details the agents for fluorescence-guided nerve imaging in both preclinical and clinical use to identify factors important in selecting nerve-specific fluorescent agents for surgical procedures.

Background: Iatrogenic nerve injury remains a significant cause of morbidity in patients undergoing surgical procedures. Current real-time identification of nerves during surgery involves neurophysiologic nerve stimulation, which has practical limitations.

Objectives: Frontal sinus anatomy is complex, and multiple variations of ethmoid pneumatization have been described that affect the frontal outflow tract. In addition, the lumen proper of the frontal sinus may exist as 2 separate parallel cavities that share an ipsilateral outflow tract. This variant has not been previously described and may have implications for surgical management.

Background: Total intravenous anesthesia (TIVA) has been proposed as a method to reduce blood loss during endoscopic sinus surgery (ESS). Impaired sinonasal visualization due to mucosal bleeding may be burdensome in cases of chronic rhinosinusitis (CRS) with high-grade inflammatory disease, suggesting a role for TIVA in that disease subgroup.

Methods: A double-blind, randomized controlled trial was conducted of adults undergoing ESS at a tertiary medical center.

Background: Tumor proliferation often occurs from pathologic receptor upregulation. These receptors provide unique targets for near-infrared (NIR) probes that have fluorescence-guided surgery (FGS) applications. We demonstrate the use of three smart-targeted probes in a model of head and neck squamous cell carcinoma.

Background: Chronic rhinosinusitis (CRS) may be initiated by innately impaired host defense mechanisms that predispose the upper airways to infection. Recent evidence suggests tethering of submucosal gland mucus strands represents an inciting event within cystic fibrosis (CF) airways, occurring prior to onset of chronic infection. Submucosal gland hypertrophy and defective mucociliary clearance (MCC) are present in actively inflamed sinuses, but mucus strand velocity may also be affected as a secondary event, further contributing to chronic disease.

Purpose Of Review: The purpose of this review is to provide otolaryngologists with the most up-to-date advancements in both the medical and surgical management of CF-related sinus disease.

Recent Findings: Recent studies have supported more aggressive CRS management, often with a combination of both medical and surgical therapies. Comprehensive treatment strategies have been shown to reduce hospital admissions secondary to pulmonary exacerbations in addition to improving CRS symptoms.

Objective: The objectives of the current experiments were to develop and characterize primary rat nasal epithelial cultures and evaluate their usefulness as a model of cystic fibrosis (CF) sinonasal transepithelial transport and CF transmembrane conductance regulator (CFTR) function.

Study Design: Laboratory in vitro and animal studies.

Methods: CFTR and CFTR rat nasal septal epithelia (RNSE) were cultured on semipermeable supports at an air-liquid interface to confluence and full differentiation.

Background: Dehydration of airway surface liquid (ASL) disrupts normal mucociliary clearance (MCC) in sinonasal epithelium, which may lead to chronic rhinosinusitis (CRS). Abnormal chloride (Cl ) transport is one such mechanism that contributes to this disorder and can be acquired secondary to environmental perturbations, such as hypoxia at the tissue surface. The objective of this study was to assess the technological feasibility of the novel micro-optical coherence tomography (μOCT) imaging technique for investigating acquired MCC defects in cultured human sinonasal epithelial (HSNE) cells.

Background And Objectives: Optical imaging to guide cancer resections is rapidly transitioning into the operating room. However, the sensitivity of this technique to detect subclinical disease is yet characterized. The purpose of this study was to determine the minimum range of cancer cells that can be detected by antibody-based fluorescence imaging.

Background: Sinus hypoplasia is a hallmark characteristic in cystic fibrosis (CF). Chronic rhinosinusitis (CRS) is nearly universal from a young age, impaired sinus development could be secondary to loss of the cystic fibrosis transmembrane conductance regulator (CFTR) or consequences of chronic infection during maturation. The objective of this study was to assess sinus development relative to overall growth in a novel CF animal model.

Comprehensive cervical lymphadenectomy can be associated with significant morbidity and poor quality of life. This study evaluated the sensitivity and specificity of cetuximab-IRDye800CW to identify metastatic disease in patients with head and neck cancer. Consenting patients scheduled for curative resection were enrolled in a clinical trial to evaluate the safety and specificity of cetuximab-IRDye800CW.

Considerable advances in cancer-specific optical imaging have improved the precision of tumor resection. In comparison to traditional imaging modalities, this technology is unique in its ability to provide real-time feedback to the operating surgeon. Given the significant clinical implications of optical imaging, there is an urgent need to standardize surgical navigation tools and contrast agents to facilitate swift regulatory approval.

Objective: Although fluorescence imaging is being applied to a wide range of cancers, it remains unclear which disease populations will benefit greatest. Therefore, we review the potential of this technology to improve outcomes in surgical oncology with attention to the various surgical procedures while exploring trial endpoints that may be optimal for each tumor type.

Background: For many tumors, primary treatment is surgical resection with negative margins, which corresponds to improved survival and a reduction in subsequent adjuvant therapies.

Background: Esophageal granular cell tumors (GCTs) are rare, often benign tumors of neurogenic origin. GCTs most frequently occur in the skin and subcutaneous tissues but are found in the gastrointestinal (GI) tract in 6%-10% of cases, with the distal two-thirds of the esophagus being the most common site. Owing to the insidious nature of GCTs, presentation is typically asymptomatic.
