Aim: To assess the risk of developing aspiration during chemoradiation for head and neck cancer.
Patients And Methods: A retrospective review of 114 patients who underwent concurrent chemoradiation for locally advanced head and neck cancer was undertaken. Patients were determined as having aspiration if they had pneumonia on chest-X-ray (CXR) and/or had documented aspiration on the modified barium swallow (MBS) during their treatment.
Results: Fifteen patients (13%) developed aspiration during chemoradiation. Twelve patients (10%) had aspiration demonstrated on CXR alone (9 patients) or combined with MBS (3 patients). Three patients (3%) had aspiration on MBS alone. Three of the six patients with aspiration observed on MBS had normal swallowing on their pretreatment MBS. All 15 patients had severe mucositis and neutropenia at the time of the aspiration. Despite broad-spectrum antibiotics and supportive care, six patients (5%) died.
Conclusion: Aspiration may develop during chemoradiation for head and neck cancer because of radiation-induced altered swallow.

Penetrating orocutaneous or oropharyngeal fistulas (POFs), severe complications following unsuccessful oral or oropharyngeal reconstruction, remain complex clinical challenges due to lack of supportive tissue, contamination with saliva and chewed food, and dynamic oral environment. Here, we present a Janus hydrogel adhesive (JHA) with asymmetric functions on opposite sides fabricated via a facile surface enzyme-initiated polymerization (SEIP) approach, which self-entraps surface water and blood within an in-situ formed hydrogel layer (RL) to effectively bridge biological tissues with a supporting hydrogel (SL), achieving superior wet-adhesion and seamless wound plugging. The tough SL hydrogel interlocked with RL dissipates energy to withstand external mechanical stimuli from continuous oral motions like chewing and swallowing, thus reducing stress-induced damage.

There is a pressing need to improve risk stratification and treatment selection for HPV-negative head and neck squamous cell carcinoma (HNSCC) due to the adverse side effects of treatment. One of the most important prognostic features is lymph nodes involvement. Previously, we demonstrated that tumor formation in patient-derived xenografts (i.

Background: Virtual surgical planning (VSP) is an emerging method in head and neck reconstruction with demonstrated benefits, however, its economic viability is supported with mixed evidence.
Methods: A structured search was performed in five electronic databases. Studies that performed an economic evaluation on VSP in head and neck reconstruction were included.

Department of Otorhinolaryngology-Head and Neck Surgery, University of Pennsylvania, Philadelphia, Pennsylvania, USA.
Background: The geriatric nutritional risk index (GNRI) is a tool to assess preoperative nutritional status that can be calculated simply based on height, weight, and serum albumin. This study assesses the utility of GNRI in predicting postoperative complications in patients undergoing major head and neck cancer (HNC) surgery.
Methods: Retrospective review of the 2016-2020 National Surgical Quality Improvement Program database.

Background: Infantile fibrosarcoma (IFS) is a rare pediatric tumor of intermediate malignancy with high local aggressiveness that typically presents in young infants. Its occurrence in the head and neck region is rare. Complete non-mutilating surgical resection is often not possible, requiring multimodal treatment.
