OBJECTIVES/OBJECTIVE:Many clinics are faced with the difficulty of evaluating performance in patients who speak a language for which there are no validated tests. It would be desirable to have a nonlinguistic method of evaluating these patients. Spectral ripple tests are nonlinguistic and highly correlated with speech identification performance. However, they are generally not amenable to clinical environments as they typically require the use of computers which are often not found in clinic sound booths. In this study, we evaluate the Spectral-temporally Modulated Ripple Test (SMRT) Lite for computeRless Measurement (SLRM), which is a new variant of the adaptive SMRT that can be implemented via a CD player. DESIGN/METHODS:SMRT and SLRM were measured for 10 normal hearing and 10 cochlear implant participants. RESULTS:Performance on the two tests was highly correlated (r = 0.97). CONCLUSIONS:The results suggest that SLRM can be used interchangeably with SMRT but can be implemented without a computer.

OBJECTIVE:Clear cell carcinoma (CCC) is a rare salivary gland malignancy, believed to be generally low grade. We investigated CCC epidemiology and clinical behavior, using the National Cancer Database (NCDB). STUDY DESIGN/METHODS:Retrospective cohort study. SETTING/METHODS:NCDB. SUBJECTS AND METHODS/METHODS:All CCCs of the salivary glands were selected between 2004 and 2015. Patient demographics, tumor characteristics, treatments, and survival were analyzed. Cox regression analyses were performed in treated patients. RESULTS:We identified 268 patients with CCC. Median age was 61 (21-90) years. Most were female (145, 54%). The most common site was oral cavity (119, 44%), followed by major salivary glands (68, 25%) and oropharynx (41, 15%). Most tumors were low grade (81, 68%) and stages I to II (117, 60.6%). Nodal (36, 17.5%) and distant metastases (6, 2.4%) were rare. Most were treated by surgery alone (134, 50.0%), followed by surgery and radiotherapy (69, 25.7%). Five-year overall survival (OS) was 77.6% (95% CI, 71.4%-84.2%). In univariate analysis, older age, major salivary gland and sinonasal site, stages III to IV, high grade, and positive margins were associated with worse OS. In multivariate analysis, only high tumor grade (hazard ratio [HR], 5.76; 95% CI, 1.39-23.85; P = .02), positive margins (HR, 4.01; 95% CI, 1.20-13.43; P = .02), and age ≥60 years (HR, 3.45; 95% CI, 1.39-8.55; P = .01) were significantly associated with OS. CONCLUSION/CONCLUSIONS:We report the largest series of clear cell carcinomas of the head and neck. Outcomes are generally favorable following surgical-based treatments. In this series, pathologic tumor grade is associated with worse survival. Routine evaluation and reporting of tumor grade might better guide physicians in recommending appropriate treatments in this rare malignancy.

Percutaneous osseointegrated bone conduction auditory devices provide excellent auditory rehabilitation. Device-related complications relate to skin abutment interface and cosmetic concerns, resulting in the development of transcutaneous devices. The Sophono and Baha Attract are safe and considered cosmetically superior to the percutaneous Baha Connect and Ponto. They provide excellent auditory enhancement; however, owing to indirect connectivity between processor and implant, there is on average 5- to 7-db less gain when compared with percutaneous bone-anchored implants. Surgical implantation of either device is usually performed under monitored sedation, in an ambulatory setting, with less than a 1-hour operative time, and minimal complications.

Oropharyngeal carcinoma associated with the human papillomavirus is increasing in incidence and represents a unique head and neck disease with favorable treatment outcomes. This review evaluates the evolving role of radiotherapy in regional management with an overall goal of treatment de-escalation in the appropriate patient. Determining the optimal approach and selection factors for treatment de-escalation is under active investigation. Response to induction chemotherapy, refining adverse pathologic factors after a primary surgical approach, decreasing radiation dose with or without chemotherapy in the definitive or adjuvant settings as well as more selective nodal level irradiation all are current strategies for treatment de-escalation. This review details the likely changes in regional radiotherapy management for oropharyngeal carcinoma in the modern human papillomavirus era and discusses future approaches to patient selection with the goal of reducing toxicities while maintaining function preservation and quality of life in group of patients who are younger and healthier than traditional head and neck cancer patients.

OBJECTIVES:/UNASSIGNED:Data on health care disparities by socioeconomic status for chronic rhinosinusitis (CRS) are lacking, and the available literature shows mixed results. The aim of this study was to evaluate several indicators of disease complexity in patients with CRS undergoing endoscopic sinus surgery between a private and a public hospital to determine if there are any disparities in the severity of disease presentation or in access to care. METHODS:/UNASSIGNED:Two hundred patients with CRS who underwent endoscopic sinus surgery from 2015 to 2017 were retrospectively reviewed. Demographics, disease-specific data, and pre- and postoperative management were collected. RESULTS:/UNASSIGNED:Public hospital patients (n = 100) were significantly more likely to be non-Caucasian (73.0% vs 25.0%, P < .0001) and to have Medicaid or no insurance (86.0% vs 4.0%, P < .0001). Patients from the public hospital were more likely to have CRS with nasal polyposis (85.0% vs 60.0%, P < .0001) and to have longer wait times for surgery (68 vs 45 days, P < .0001) and were more likely to be lost to follow-up (26.0% vs 16.0%, P = .031). Patients at the public hospital had CRS symptoms 21% longer ( P = .0206), and if a patient carried a diagnosis of asthma, he or she had on average more severe asthma ( P = .0021). CONCLUSIONS:/UNASSIGNED:This study suggests that patients of lower socioeconomic status had a longer duration of disease prior to surgery, more often had nasal polyposis, and had decreased access to care, as indicated by increased surgical wait times and being lost to follow-up. Acting as a foundation for further investigation, the ultimate intent of this study is to improve care for all patients.

BACKGROUND:Injection medialization is performed to improve glottic closure, thereby airway protection. Overall objective to determine if unilateral injection medialization changes glottal area with concomitant adjustments in penetration/aspiration scale (PAS) scores and pharyngeal high-resolution manometry (HRM) parameters. METHODS:Enrolled 17 adults with unilateral vocal fold paralysis/paresis and aspiration/penetration. Fiberoptic endoscopic evaluation of swallowing and pharyngeal HRM completed at (1) baseline (within 1 week before injection), (2) postinjection (within 1 week post injection), and (3) 1-month postinjection. Comparisons between time points for PAS scores, glottal area, pharyngeal pressure, and timing. RESULTS:No significant differences in normalized glottal area. No significant differences in PAS scores, for any consistency. Significantly increased rate of mesopharynx pressure rise and maximum pressure at 1 month postinjection (P = .01 and .02, respectively) compared to baseline. Significant decrease in mesopharynx integral from baseline to 1 week postoperative (P = .03). CONCLUSION/CONCLUSIONS:Findings suggest unilateral vocal fold injection medialization had limited effect on swallow function.

Purpose/UNASSIGNED:The aim of this study was to investigate improvements in swallowing function and physiology in a series of healthy older adults with radiographically confirmed dysphagia, following completion of an exercise-based swallowing intervention. Patients and methods/UNASSIGNED:Nine otherwise healthy older adults (six females, mean age =75.3, SD =5.3) had confirmed impairments in swallowing safety and/or efficiency on a modified barium swallow study. Each participant completed an 8-week swallowing treatment protocol including effortful swallows, Mendelsohn maneuvers, tongue-hold swallows, supraglottic swallows, Shaker exercises and effortful pitch glides. Treatment sessions were conducted once per week with additional daily home practice. Penetration-Aspiration Scale and the Modified Barium Swallowing Impairment Profile (MBSImP) were scored in a blind and randomized fashion to examine changes to swallowing function and physiology from baseline to post-treatment. Results/UNASSIGNED:There were significant improvements in swallowing physiology as represented by improved oral and pharyngeal composite scores of the MBSImP. Specific components to demonstrate statistical improvement included initiation of the pharyngeal swallow, laryngeal elevation and pharyngeal residue. There was a nonsignificant reduction in median PAS scores. Conclusion/UNASSIGNED:Swallowing physiology can be improved using this standardized high-intensity exercise protocol in healthy adults with evidence of dysphagia. Future research is needed to examine the individual potential of each exercise in isolation and to determine ideal dose and frequency. Studies on various etiological groups are warranted.

Statistical learning has been proposed as a possible mechanism by which individuals can become sensitive to the structures of language fundamental for speech perception. Since its description in human infants, statistical learning has been described in human adults and several non-human species as a general process by which animals learn about stimulus-relevant statistics. The neurobiology of statistical learning is beginning to be understood, but many questions remain about the underlying mechanisms. Why is the developing brain particularly sensitive to stimulus and environmental statistics, and what neural processes are engaged in the adult brain to enable learning from statistical regularities in the absence of external reward or instruction? This review will survey the statistical learning abilities of humans and non-human animals with a particular focus on communicative vocalizations. We discuss the neurobiological basis of statistical learning, and specifically what can be learned by exploring this process in both humans and laboratory animals. Finally, we describe advantages of studying vocal communication in rodents as a means to further our understanding of the cortical plasticity mechanisms engaged during statistical learning. We examine the use of rodents in the context of pup retrieval, which is an auditory-based and experience-dependent form of maternal behavior.
