Background Sinonasal mucosal melanoma has poor survival despite multimodality treatment. While the impact of immunotherapy (IT) on metastatic cutaneous melanoma is well-defined, there are relatively little data on sinonasal mucosal melanoma. Objective We sought to define immunotherapy outcomes in patients with sinonasal mucosal melanoma. Methods A retrospective cohort study evaluated patients treated with IT during their overall treatment strategy for SNMM. Patient demographics, treatment, and survival outcomes were recorded. Results 52 patients had IT treatment for SNMM from 2000 to 2022, with an average age of 69.1 ± 11.9 years. The most common treatment was surgery with radiation and IT ( n = 26, 50%). Most regimens consisted of a combination of Nivolumab and Ipilimumab ( n = 17, 32.7%) or pembrolizumab ( n = 14, 26.9%). 44.2% of patients experienced reported complications. Overall survival at 1-, 2-, and 5 years was 86.9%, 74.1%, and 39.1%, respectively. Conclusion Approximately half of patients will have a local response following immunotherapy, but it is rare to have improvement at metastatic locations. Further research within our group will assess optimal timing and markers that are predictive of response.

IntroductionUnilateral sphenoid sinus opacification on computed tomography is caused by a variety of pathologies including inflammatory and infectious sinusitis, benign and malignant tumors, and encephaloceles. The purpose of this study was to report craniofacial pain locations and outcomes in inflammatory unilateral sphenoid sinusitis (USS) patients who underwent endoscopic sinus surgery (ESS).MethodsA multi‐institutional retrospective cohort study was conducted on all adult patients who had ESS for USS from 2015 to 2022. Patient demographics, presenting symptoms and nasal endoscopy findings, extent of surgical dissection, and craniofacial pain locations and outcomes were recorded. Exclusion criteria included age <18 years, non‐inflammatory etiology, immunodeficiency, invasive fungal sinusitis, lack of follow‐up, lack of preoperative pain location, and neoplasia. Descriptive statistics were calculated.ResultsOf 57 patients with USS, 44 (77.2%) reported craniofacial pain at one or more locations. Retrobulbar (n = 19, 43.2%) was the most common pain location followed by frontal (n = 17, 38.6%) and occipital (n = 10, 22.7%). Surgical intervention resulted in pain resolution in 33/44 patients (75%), with a mean follow‐up of 83.7 (±97.8) days. There were no significant associations between presenting symptoms, imaging findings, endoscopy, surgical extent, or final pathology and the presence or resolution of facial pain (p > 0.05).ConclusionIn USS patients, the most common craniofacial pain locations were retrobulbar, occipital, and frontal, with a minority being vertex. Based on short‐term follow‐up, ESS resolved the craniofacial pain in 75% of cases. There were no clinical variables that predicted the presence or resolution of craniofacial pain.Level of Evidence4 Laryngoscope, 135:1915–1919, 2025

Abstract Dementia caregivers are at heightened risk for developing mental and physical health problems. Interventions designed to protect caregiver health often create additional demands on time and energy (e.g., exercise programs). Technology-based interventions (e.g., remote monitoring) can be effective, scalable, and do not add greatly to caregiver burden. Through a collaboration with a local technology company, Care Daily, we conducted two randomized controlled trials to evaluate People Power Caregiver (PPCg), a system of sensors in the home connected to cloud-based AI that alerts caregivers about worrisome deviations from normal patterns (e.g., care-recipient’s falls, wandering). Across two studies (study 1: 9-month duration with professional installation of PPCg; study 2: 6-month duration with caregiver self-installing the PPCg using remote tech support), 284 caregivers were recruited; 261 completed initial study deployment (e.g., system installation); and 235 completed the entire study protocol. Use of PPCg was associated with (a) reduced caregiver anxiety in study 1; (b) greater protection from declines in sleep efficiency in studies 1 and 2. These findings underscore the promise of technology-based intervention to mitigate health problems in dementia caregivers. However, challenges and complexities in recruitment (e.g., remote consenting both caregivers and care recipients), retention (e.g., due to changes in home environment or caregiving status), system installation (e.g., working with caregivers with less experience using technology), data quality assurance (e.g., invalid sensor data) as well as our efforts to overcome these challenges have been instructive. Lessons learned from these studies can provide useful guidance for future large-scale, technology-based interventions for dementia caregivers.

AbstractObjectiveCritical components of the nasal endoscopic examination have not been definitively established for either the normal examination or for clinical disorders. This study aimed to identify concordance among rhinologists regarding the importance of examination findings for various nasal pathologies.Study DesignA consortium of 19 expert rhinologists across the United States was asked to rank the importance of findings on nasal endoscopy for 5 different sinonasal symptom presentations.SettingAn online questionnaire was distributed in July 2023.MethodsThe questionnaire utilized JotForm® software and featured 5 cases with a set of 4 identical questions per case, each covering a common indication for nasal endoscopy. Rankings were synthesized into Normalized Attention Scores (NASs) and Weighted Normalized Attention Scores (W‐NASs) to represent the perceived importance of each feature, scaled from 0 to 1.ResultsGeneral concordance was found for examination findings on nasal endoscopy within each case. The perceived features of importance differed between cases based on clinical presentation. For instance, in evaluating postnasal drip, the middle meatus was selected as the most important structure to examine (NAS, 0.73), with mucus selected as the most important abnormal finding (W‐NAS, 0.66). The primary feature of interest for mucus was whether it was purulent or not (W‐NAS, 0.67). Similar analyses were performed for features in each case.ConclusionThe implicit framework existing among rhinologists may help standardize examinations and improve diagnostic accuracy, augment the instruction of trainees, and inform the development of artificially intelligent algorithms to enhance clinical decision‐making during nasal endoscopy.

Abstract Background Sinonasal malignancies with orbital invasion have dismal prognosis even when treated with orbital exenteration (OE). Sugawara et al. developed a surgical strategy called “extended‐OE (EOE),” showing encouraging outcomes. We hypothesized that a similar resection is achievable under endoscopic guidance through the exenterated orbit (endoscopic‐EOE). Methods The study was conducted in three institutions: University of Vienna; Mayo Clinic; University of Insubria; 48 orbital dissections were performed. A questionnaire was developed to evaluate feasibility and safety of each step, scoring from 1 to 10, (“impossible” to “easy,” and “high risk” to “low risk,” respectively), most likely complication(s) were hypothesized. Results The step‐by‐step technique is thoroughly described. The questionnaire was answered by 25 anterior skull base surgeons from six countries. Mean, median, range, and interquartile range of both feasibility and safety scores are reported. Conclusions Endoscopic‐EOE is a challenging but feasible procedure. Clinical validation is required to assess real‐life outcomes.

AbstractPurposeSinonasal malignancies (SNMs) adversely impact patients’ quality of life (QOL) and are frequently identified at an advanced stage. Because these tumors are rare, there are few studies that examine the specific QOL areas that are impacted. This knowledge would help improve the care of these patients.MethodsIn this prospective, multi‐institutional study, 273 patients with SNMs who underwent definitive treatment with curative intent were evaluated. We used the University of Washington Quality of Life (UWQOL) instrument over 5 years from diagnosis to identify demographic, treatment, and disease‐related factors that influence each of the 12 UWQOL subdomains from baseline to 5 ‐years post‐treatment.ResultsMultivariate models found endoscopic resection predicted improved pain (vs. nonsurgical treatment CI 2.4, 19.4, p = 0.01) and appearance versus open (CI 27.0, 35.0, p < 0.001) or combined (CI 10.4, 17.1, p < 0.001). Pterygopalatine fossa involvement predicted worse swallow (CI −10.8, −2.4, p = 0.01) and pain (CI −17.0, −4.0, p < 0.001). Neck dissection predicted worse swallow (CI −14.8, −2.8, p < 0.001), taste (CI −31.7, −1.5, p = 0.02), and salivary symptoms (CI −28.4, −8.6, p < 0.001). Maxillary involvement predicted worse chewing (CI 9.8, 33.2; p < 0.001) and speech (CI −21.8, −5.4, p < 0.001) relative to other sites. Advanced T stage predicted worse anxiety (CI −13.0, −2.0, p = 0.03).ConclusionsSurgical approach, management of cervical disease, tumor extent, and site of involvement impacted variable UWQOL symptom areas. Endoscopic resection predicted better pain, appearance, and chewing compared with open. These results may aid in counseling patients regarding potential QOL expectations in their SNM treatment and recovery course.

Abstract Objective . Conventional computed tomography (CT) imaging does not provide quantitative information on local thermal changes during percutaneous ablative therapy of cancerous and benign tumors, aside from few qualitative, visual cues. In this study, we have investigated changes in CT signal across a wide range of temperatures and two physical phases for two different tissue mimicking materials, each. Approach . A series of experiments were conducted using an anthropomorphic phantom filled with water-based gel and olive oil, respectively. Multiple, clinically used ablation devices were applied to locally cool or heat the phantom material and were arranged in a configuration that produced thermal changes in regions with inconsequential amounts of metal artifact. Eight fiber optic thermal sensors were positioned in the region absent of metal artifact and were used to record local temperatures throughout the experiments. A spectral CT scanner was used to periodically acquire and generate electron density weighted images. Average electron density weighted values in 1 mm 3 volumes of interest near the temperature sensors were computed and these data were then used to calculate thermal volumetric expansion coefficients for each material and phase. Main results . The experimentally determined expansion coefficients well-matched existing published values and variations with temperature—maximally differing by 5% of the known value. As a proof of concept, a CT-generated temperature map was produced during a heating time point of the water-based gel phantom, demonstrating the capability to map changes in electron density weighted signal to temperature. Significance . This study has demonstrated that spectral CT can be used to estimate local temperature changes for different materials and phases across temperature ranges produced by thermal ablations.

AbstractThis study aimed to compare the clinically established autologous extrasynovial tendon graft to a newly developed tissue‐engineered allograft (Eng‐allograft) in terms of functional outcomes following flexor tendon reconstruction in a canine model. The second and fifth flexor digitorum profundus (FDP) tendons from 16 dogs were transected and repaired in Zone II. After 6 weeks of cage activity, the repaired tendons were intentionally ruptured, creating a clinically relevant model for reconstruction. The re‐ruptured FDP tendons were then reconstructed using either the clinically standard autologous extrasynovial tendon graft or the Eng‐allograft, which had been revitalized with autologous bone marrow‐derived mesenchymal stem cells (BMSCs) and synovialized using carbodiimide derivatized synovial fluid (cd‐SYN). Following 12 weeks of postoperative rehabilitation, the functional outcomes of the surgical digits were evaluated. The Eng‐allograft group exhibited improved digital function, including lower digit work of flexion and reduced adhesion status, while maintaining similar tendon gliding resistance compared to the autograft group. However, the failure load of both the distal and proximal host/graft conjunctions in the Eng‐allograft group was significantly lower than that of the autograft group with higher graft rupture at the host−graft junction. In conclusion, the decellularized allogenic intrasynovial tendon, when revitalized BMSCs and synovialized with cd‐SYN, demonstrates positive effects on digital function improvement and adhesion reduction. However, the healing at both proximal and distal graft/host junctions is far lower than the autograft. Further research is needed to enhance the healing capacity of allograft conjunctions, aiming to achieve a comparable level of healing seen with autografts.
