CO Laser and Coblation are widely used in Head and neck Surgeries. This study compares the tissue changes produced by these two techniques. 50 Patients who underwent complete excision of benign and malignant pathologies in the Oral Cavity, Oropharynx, and Larynx with Coblation and CO Laser were included in the study. The primary excised specimen and another separate specimen from the base of the excised lesion were evaluated histologically based on criteria by Vescovi et al. (1). On histopathological examination, thermal effects (epithelial, connective tissue and vascular) produced by both techniques were comparable. However vascular changes were seen more in tissues CO Laser ( = 0.727). Incision margins were more regular in the CO Laser group (73%) than in Coblation (55%) but not statistically significant ( = 1.80). Depth of thermal damage ( = 0.171) and connective tissue changes( = 0.279) was more with Coblation. Both Coblation and CO Laser can be used effectively in Head and Neck cases. CO Laser, when available, is a better option because of its precise excision, and less collateral tissue damage.

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.

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.
