Pre-calculated airflow resistance, wall shear stress, pressure drop are displayed on the anatomy to identify potential sites of obstruction. After each virtual surgery, changes in nasal airflow can be computed, and the process is reiterated until an optimal result is reached.\u0000Results\u0000As proof-of-concept, a series of isolated or combined procedures were performed on CT of one patient, who had olfactory losses that may involve obstructions blocking the air/odor flow to the olfactory fossa (OF). For this patient, an isolated medial partial middle turbinectomy (PMT) demonstrated the best outcome, better than traditionally performed lateral PMT, while septal body reduction worsened air/odor flow to OF. Conclusion\u0000This proof of concept case report demonstrates the potential usefulness of VSP in preoperative planning based on objective benchmarks and could be a valuable tool for optimizing future surgical outcomes.","PeriodicalId":501185,"journal":{"name":"medRxiv - Otolaryngology","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142265952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding how these phenomena are intertwined and how aging affects those is crucial for prevention and the future development of interventions.\u0000Methods: We utilized the UK Biobank which includes a total of 502,382 participants between 40 and 70 years old. We used logistic regression models and cox proportional hazard models and compared hazard ratios.\u0000Results: The odds of reporting tinnitus in the older age group (i.e., older than 58 years) were increased by 43.3% and a one decibel increase in the SRT enhanced the odds for tinnitus by 13.5%. For our second analysis regarding hearing loss, the risk of dementia increased by 9.2% with an increase by one decibel in the SRT score. In terms of aging, each additional year increased the risk by 19.2%. Tinnitus alone showed a significant influence with a hazard ratio of 52.1%, however, when adding hearing loss, age and various covariates, the effect vanished.\u0000Conclusion: Findings confirm that tinnitus is indeed related to aging, but presumably independent of the aging processes accompanying the development of dementia. This highlights the urge to further investigate the impact of aging on neural processes that are relevant for alterations in the auditory systems (e.g., leading to the development of tinnitus or hearing loss) as well as for increased vulnerability in terms of neurodegenerative diseases.\u0000Keywords: ageing, dementia, hearing loss, tinnitus, UK Biobank","PeriodicalId":501185,"journal":{"name":"medRxiv - Otolaryngology","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141863619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The HN-LEF grading system classifies physically palpable soft-tissue injury categorically. Imaging biomarkers from MRI may serve to complement or validate physical HN-LEF grading when assessing the effectiveness of therapeutic interventions or toxicity profiles of patients.\u0000Objective To explore the relationship between 1) physical HN-LEF classification in submental and oral regions of interest (ROI) and the MRI T1- and T2-weighted signal intensity (SI) in close proximity regions, and 2) a novel HN-LEF score and MRI T1 and T2 structural volumes. Design: Post hoc analysis of pilot single-arm MANTLE trial (NCT03612531).\u0000Setting: Single institution, NCI-designated comprehensive cancer center. Participants A total of 16 individuals (mean [SD] age, 68.28 [7.0] years; 3[19%] female) enrolled in the MANTLE trial underwent MRI. All participants were disease-free at least two years post radiotherapy with grade ≥2 fibrosis (in any cervical ROI) and grade ≥2 dysphagia (per DIGEST). Over a 12-week period, participants engaged in manual therapy sessions accompanied by concurrent standardized multiparametric, serial MRI examinations and palpation-based HN-LEF evaluations at 3-time points: baseline, post-manual therapy, and post-washout.\u0000Exposures: The independent variable HN-LEF included its categorical classification (No-LEF, A-B = edema, C= edema + fibrosis, D=fibrosis) and a novel metric (10-point scale) derived from the HN-LEF categories (considering both type and severity classification).\u0000Main Outcomes and Measures: The T1- and T2-weighted MRI SI was examined by Kruskal-Wallis tests in relation to HN-LEF categories and the novel HN-LEF score. We hypothesized higher T2 SI in edema states, higher T1 SI in fibrotic states, and decreasing structural volume as the HN-LEF score increased. Results: We identified differences in mean ranks among HN-LEF categories in relation to the MRI SI (A-B and C are higher than D and No-LEF for T2 SI, and A-B is the highest for T1). Furthermore, six pairs of FOM volumes on MRI demonstrated a strong negative correlation (p&lt;0.05) with the HN-LEF score at adjacent palpable sites: digastric vs. submental left (ρ = -0.421; 95% CI, -0.65~ -0.10, T1), mylohyoid vs. submental left (ρ = -0.36; 95% CI, -0. 62~ 0.03, T1), digastric vs. submental left (ρ = --0.45; 95% CI, -0. 72~ -0.06, T2), genioglossus vs. Intraoral left (ρ = -0.47; 95% CI, -0. 74~ -0.07, T2), mylohyoid vs. Intraoral left (ρ = -0.48; 95% CI, -0. 75~ -0.09, T2), tongue base vs. Intraoral left (r = -0.42; 95% CI, -0. 71~ -0.01, T2).\u0000Conclusions and Relevance This exploratory analysis provides hypothesis-generating data supporting further study of MRI SI as an imaging biomarker of edematous soft tissue states after RT in HNC, but does not support the hypothesized T2 SI relationship ","PeriodicalId":501185,"journal":{"name":"medRxiv - Otolaryngology","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141530225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study aimed to examine the impact of instructions on the prioritization strategy employed by individuals during a dual-task paradigm for listening effort by assessing dual-task interference. <strong>Methods</strong> The dual-task paradigm consisted of a primary speech understanding task in different listening conditions and a secondary visual memory task, both performed separately (baseline) and simultaneously (dual-task). Twenty-three normal-hearing participants (mean age: 36.8 years; 14 females) were directed to prioritize the primary speech understanding task in the dual-task condition, whereas another twenty-three (matched for age, gender, and education level) received no specific instructions regarding task priority. Both groups performed the dual-task paradigm twice (mean interval: 14.8 days). Dual-task interference was assessed by plotting the dual-task effect of the primary and secondary task against each other. Participants were classified based on their patterns of interference. <strong>Results</strong> The prioritizing group had more participants who achieved stable or better scores on the primary task in the dual-task condition compared to baseline. However, there was considerable variability in the prioritizing strategy employed at the individual level across listening conditions and test moments, regardless the given prioritization instructions. <strong>Conclusion</strong> Providing prioritization instructions was insufficient to ensure that an individual will mainly focus on the primary task and will stick to this strategy across listening conditions and test moments. These results raised certain reservations about the current usage of dual-task paradigms for listening effort.","PeriodicalId":501185,"journal":{"name":"medRxiv - Otolaryngology","volume":"59 13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141510672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adherence to the olfactory training regimen is, however, generally low. We aimed to investigate if a new form of olfactory delivery via scented nasal inserts could enhance olfactory training adherence by allowing participants to be mobile while performing the training and thereby lower perceived intrusion in their everyday life, using a randomized controlled parallel-group design. Two groups of individuals with hyposmia underwent 8 weeks of olfactory training. One group (n=60) performed olfactory training using scented nasal inserts (nasal plugs that retain nasal patency) and one group (n=56) performed the standard care regiment currently recommended by the Swedish healthcare system. We assessed objective and subjective olfactory ability before and after olfactory training as well as adherence to training. While both groups significantly improved their objective and subjective olfactory abilities, training with nasal insert produced similar improvement as standard care in overall treatment outcome. However, there was a significantly greater increase in discrimination performance and lower dropout rate (6.7%) in the nasal insert compared to the standard care group (23.2%). Critically, the nasal insert group had a significantly higher adherence to the training regimen, i.e. fewer missed training sessions. In addition, they reported overall greater satisfaction with their treatment. These data suggest that olfactory training with nasal inserts could serve as a more effective form of treatment for hyposmia, due to patients improved adherence to protocol and increased tendency to finish their treatment regimen.","PeriodicalId":501185,"journal":{"name":"medRxiv - Otolaryngology","volume":"118 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141510504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
