We describe a case series of 6 metastatic/locoregionally recurrent HPVOPSCC patients with FGFR alterations.

Contemporary Approaches to Head and Neck Reconstruction.

This article aims to provide an update on techniques related to head and neck reconstruction using microvascular free tissue transfer, focusing on strategies for donor vessel selection in the vessel depleted neck, use of vein grafting and mechanical arterial coupling, estimating flap volume loss, and utilization of virtual planning and medical modeling for midface and mandibular reconstruction.

Free Flap Enhanced Recovery Protocols in Head and Neck Surgery.

Enhanced recovery after surgery (ERAS) protocols facilitates a standardized patient care regimen with a goal of reducing the metabolic stress of surgery. Adapted to head and neck free flap reconstructive surgery in 2017, these protocols focused on several key domains such as perioperative nutritional optimization, multimodal pain control, and early mobilization. Studies have shown that in addition to ERAS implementation, the maintenance and improvement of ERAS protocol compliance rates improve perioperative outcomes such as hospital length of stay and decrease major postoperative complications.

Local control of pediatric head and neck sarcoma with free flap reconstruction obviating the need for radiotherapy: a case report.

Background: Microvascular free-tissue transfer is a widely used technique for surgical site reconstruction following head and neck mass resection. While it is commonly used in adults, the rarity of head and neck cancers in children makes free flap reconstruction relatively rare in this population. Free flap reconstruction allows for coverage of large defects which may result from wide resections performed to avoid exposing pediatric patients to primary radiotherapy.

The osteocutaneous radial forearm free flap: A multidisciplinary review of the evidence.

The osteocutaneous radial forearm (OCRFF) is a versatile free flap option for bony defects of the head and neck, given the thinness and pliability of the forearm cutaneous paddle, pedicle length, reliability, lack of atherosclerosis, and functional concerns common to other osseous donor sites. The OCRFF was once associated with a high risk of radial fracture, in addition to concerns about the quality and durability of bone stock for osseous reconstruction, particularly for the mandible. Following the introduction of prophylactic plating of the radius, the incidence of symptomatic radial fracture has drastically decreased.

The osteocutaneous radial forearm free flap: A pictorial essay.

The osteocutaneous radial forearm free flap (OCRFFF) is a versatile flap with the ability to reconstruct complex defects. We detail the techniques necessary to harvest an OCRFFF, including an outline on making 90-degree osteotomies to maximize bone harvest. In this pictorial essay, we provide illustrations of the anatomy and surgical techniques necessary for OCRFFF harvest.

Importance: As the incidence of oropharyngeal squamous cell carcinoma (OPSCC) continues to rise in the US, an increasing number of patients are being treated with transoral robotic surgery (TORS). Readmission following surgery can potentially delay initiation of adjuvant treatment and affect survival outcomes.

Objective: To identify risk factors for 30-day postoperative readmission in patients undergoing TORS for OPSCC.

Efficacy and safety of near-infrared fluorescence identification of the thoracic duct during left lateral neck dissection.

Background: Thoracic duct leaks occur in up to 5% of left lateral neck dissections. No one imaging modality is routinely used to identify the thoracic duct intraoperatively. The goal of our study was to evaluate the efficacy and safety of indocyanine green lymphangiography for intraoperative identification of the thoracic duct compared to traditional methods using ambient and evaluate the optimal timing of indocyanine green administration.

Single-Cell RNA-Seq Analysis of Patient Myeloid-Derived Suppressor Cells and the Response to Inhibition of Bruton's Tyrosine Kinase.

Unlabelled: Myeloid-derived suppressor cell (MDSC) levels are elevated in patients with cancer and contribute to reduced efficacy of immune checkpoint therapy. MDSC express Bruton's tyrosine kinase (BTK) and BTK inhibition with ibrutinib, an FDA-approved irreversible inhibitor of BTK, leads to reduced MDSC expansion/function in mice and significantly improves the antitumor activity of anti-PD-1 antibody treatments. Single-cell RNA sequencing (scRNA-seq) was used to characterize the effect of ibrutinib on gene expression of fluorescence-activated cell sorting-enriched MDSC from patients with different cancer types [breast, melanoma, head and neck squamous cell cancer (HNSCC)].

Importance: Historical data reveal that, compared with women, men are more likely to pursue a head and neck surgical oncology fellowship, but little is known about possible gender differences in academic productivity.

Objective: To assess demographic trends and academic productivity among American Head & Neck Society (AHNS) fellowship graduates.

Design, Setting, And Participants: This cross-sectional study used electronically published data from the AHNS on fellowship graduates in the US and Canada from July 1, 1997, to June 30, 2022.

Internal jugular vein reconstruction: An algorithm for reconstructive surgeons.

Objectives: The internal jugular vein (IJV) provides critical drainage from the brain, skull, and deep regions of the face and neck. Compromise to the bilateral IJVs has severe sequelae, but even unilateral IJV sacrifice or thrombosis after treatment can have sequelae. Despite the potential role of IJV reconstruction for head and neck surgeons, information about the indications, technique, and outcomes of the procedure are sparse.

Body Mass Index (BMI) Related Morbidity with Thyroid Surgery.

Objectives: The increase in incidence of thyroid cancer correlates with strict increases in body mass index (BMI) and obesity in the United States. Thyroid hormone dysregulation has been shown to precipitate circulatory volume, peripheral resistance, cardiac rhythm, and even cardiac muscle health. Theoretically, thyroid surgery could precipitate injury to the cardiopulmonary system.

History, Innovation, Pearls, and Pitfalls in Complex Midface Reconstruction.

Midface reconstruction in head and neck cancer or individuals with extensive trauma to the face has evolved significantly over the past few decades with the introduction of free flap reconstruction and virtual surgical planning enabling surgeons to obtain optimal cosmetic and functional outcomes. Traditional methods such as the use of obturators or local flaps still have a role in select situations, but complex defects have been replaced by the advent of microvascular free tissue transfer and virtual planning, which can commonly provide a single-stage reconstruction of the midface with excellent aesthetic and functional results. This article provides an overview of the history and evolution of midface reconstruction, a discussion of how to integrate virtual surgical planning into a surgical practice, an example of a complex midface reconstruction case, and pearls and pitfalls that have been experienced by an experienced reconstructive team.
