Purpose: Managing postoperative complications is crucial in reconstructive surgery. Indocyanine green fluorescence video-angiography (ICGA) aids in assessing flap vascularization intraoperatively, potentially reducing complications.
Methods: An ambispective study enrolled head and neck cancer patients undergoing ablative surgery with soft tissue reconstruction. An experimental arm (March 2021-May 2023) used ICGA, while a control arm (January 2017-December 2020) did not. Complications were graded by Clavien-Dindo classification. We also evaluated the effect of systemic inflammation on the sensitivity of ICGA in detecting hypoperfused areas of the flap.
Results: Complications were less frequent in the experimental arm, both overall (11.4% vs. 36.4%) and major ones (Clavien-Dindo ≥ 3) (8.6% vs. 30.9%). ICGA showed a protective effect in univariate and multivariate analyses. Previous radiation and ICGA were independent predictors of major complications. ICGA altered the surgical strategy in 25.7% of cases.
Conclusions: Real-time perfusion assessment, particularly with ICGA, can improve outcomes in head and neck cancer patients undergoing soft tissue reconstruction by reducing complications. Further research with larger cohorts is warranted for validation.

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.
