Impact of Socioeconomic Demographics and Race on Laryngotracheal Stenosis Etiology and Outcomes

alexandrossfakianakis shared this article with you from Inoreader Impact of Socioeconomic Demographics and Race on Laryngotracheal Stenosis Etiology and Outcomes via The Laryngoscope Our retrospective cohort study identified that Black patients comprised the greatest proportion of patients with iatrogenic laryngotracheal stenosis. Of all etiologies, the iatrogenic form of stenosis had the highest incidence of temporary tracheostomy and tracheostomy dependence. Objective Certain sociodemographic variables are known to result in health care disparities. This study investigates potential differences in outcomes for patients with laryngotracheal stenosis (LTS) based on racial backgrounds and socioeconomic variables including insurance status and English language-Proficiency. Methods Patients with LTS from 2016 to 2021were identified by relevant ICD codes. Variables including race, age, gender, language preference and insurance status were collected from medical records. Risk factors for LTS including COPD, smoking history, diabetes, GERD, and BMI were obtained. Etiology of LTS was categorized as autoimmune, traumatic, iatrogenic, or idiopathic. Need for temporary tracheostomy and tracheostomy dependence were determined at last follow-up visit. Results 129 patients were included for review. 70% of Black patients had iatrogenic LTS, whereas 65% of the White patient cohort had autoimmune or idiopathic LTS. Black patients were more strongly associated with temporary tracheostomy and tracheostomy dependence compared to White patients. Public health insurance and co-morbid GERD were associated with tracheostomy dependence for White patients only. Conclusion This study identified a disproportionate representation of Black patients in the iatrogenic etiology of LTS. Although controlling for risk factors of LTS, this cohort had an increased need for temporary tracheostomy and tracheostomy dependence compared to White and Latinx cohorts. This finding merits further study. Level of Evidence III Laryngoscope, 2022 View on Web

The Impact of Vocal Boost Manipulations on Musical Sound Quality for Cochlear Implant Users

alexandrossfakianakis shared this article with you from Inoreader The Impact of Vocal Boost Manipulations on Musical Sound Quality for Cochlear Implant Users via The Laryngoscope CI users face significant difficulty with music perception, which negatively impacts sound quality and music appreciation. Our study demonstrates commercially available vocal boost software can be used to improve the perception of musical sound quality appraisals among CI users, which may contribute positively to quality of life. Given these findings, front-end vocal manipulations and settings should be considered as an adjunct to current methods of hearing accessibility and accommodations for CI music listening experiences. Objective To evaluate the impact of vocal boost manipulations on cochlear implant (CI) musical sound quality appraisals. Methods An anonymous, online study was distributed to 33 CI users. Participants listened to auditory tokens and assessed the musical quality of acoustic stimuli with vocal boosting and attenuation using a validated sound quality rating scale. Four versions of real-world musical stimuli were created: a version with +9 dB vocal boost, a version with −9 dB vocal attenuation, a composite stimulus containing a 1,000 Hz low-pass filter and white noise ("anchor"), and an unaltered version ("hidden reference"). Subjects listened to all four versions and provided ratings based on a 100-point scale that reflected the perceived sound quality difference of the music clip relative to the reference excerpt. Results Vocal boost increased musical sound quality ratings relative to the reference clip (11.7; 95% CI, 1.62–21.8, p = 0.016) and vocal attenuation decreased musical sound quality ratings relative to the reference clip (28.5; 95% CI, 18.64–38.44, p < 0.001). When comparing the non-musical training group and musical training group, there was a significant difference in musical sound quality rating scores for the vocal boost condition (21.2; 95% CI: 1.76–40.7, p = 0.028). Conclusions CI-mediated musical sound quality appraisals are impacted by vocal boost and attenuation. Musically trained CI users to report greater musical sound quality enhancement with a vocal boost with respect to CI users with no musical training background. Implementation of front-end vocal boost manipulations in music may improve sound quality and music appreciation among CI users.

Free Tissue Transfer for Skull Base Osteoradionecrosis: A Novel Approach in the Endoscopic Era

alexandrossfakianakis shared this article with you from Inoreader Free Tissue Transfer for Skull Base Osteoradionecrosis: A Novel Approach in the Endoscopic Era via The Laryngoscope Osteoradionecrosis (ORN) of the skull base and the craniovertebral junction is a challenging complication of radiation therapy. We describe an endoscopic-assisted approach for the management of ORN of the skull base using fascia lata for microvascular free tissue transfer. This approach is a novel and effective strategy for the management of ORN of the skull base and upper cervical spine with excellent postoperative outcomes and limited patient morbidity. Objectives Osteoradionecrosis (ORN) of the skull base and craniovertebral junction is a challenging complication of radiation therapy (RT). Severe cases often require surgical intervention through a multi-modal approach. With the evolution in endoscopic surgery and advances in skull base reconstruction, there is an increasing role for microvascular free tissue transfer (MFTT). We describe an endoscopic-assisted approach for the management of ORN of the skull base using fascia lata for MFTT. Study Design Retrospective case series. Methods Between 2017 and 2021, a review of all cases in which fascia lata MFTT was utilized for skull base ORN was performed. Patient demographics, preoperative characteristics, and postoperative outcomes with long-term follow-up were reviewed. Results Five patients were identified. Mean duration to onset of ORN was 17 months following RT. A trial of antibiotics, hyperbaric oxygen (HBO), and/or limited debridement was attempted without success. Refractory pain and progressive osteomyelitis were unifying symptoms. All patients underwent endoscopic debridement of the affected region of ORN prior to MFTT. Vascularized fascia lata was inset through a combined endonasal and transoral corridor. There was improvement in chronic pain in the postop setting with no patients requiring continued antibiotics or HBO therapy. Mean post-op follow-up was 23 months. Conclusions With continued evolution in endoscopic, minimally invasive approaches, there is an expanding indication for early surgical management in refractory ORN. Fascia lata MFTT is a novel and effective strategy for the management of ORN of the skull base and upper cervical spine with excellent postoperative outcomes and limited patient morbidity.

Long‐Term Outcomes of End‐Flexible‐Rigidscopic Transoral Surgery for Pharyngolaryngeal Cancer

alexandrossfakianakis shared this article with you from Inoreader Long‐Term Outcomes of End‐Flexible‐Rigidscopic Transoral Surgery for Pharyngolaryngeal Cancer via The Laryngoscope Objective End-flexible-rigidscopic transoral surgery (E-TOS) is a new and minimally invasive transoral surgery for resection of Tis-selected T3 pharyngolaryngeal cancers. We evaluated long-term oncological outcomes and whether postoperative voice and swallowing function were preserved following E-TOS. Methods In this retrospective single-center study, 154 patients treated with E-TOS using a curved retractor, flexible-tip rigid endoscope, and thin curved instruments were included. Their survival rate, larynx preservation rate, and disease control rate were estimated using the Kaplan–Meier method. Postoperative voice function was evaluated using both objective and subjective tests. Postoperative swallowing function was assessed using the Hyodo score and the functional outcome swallowing scale. Results The 3-year and 5-year overall survival, disease-specific survival, disease-free survival, laryngectomy-free survival, local control, and loco-regional control rates post E-TOS were 89.8% and 82.2%, 95.6% and 92.3%, 78.5% and 70.3%, 87.2% and 80.9%, 93.9% and 92.5%, and 87.2% and 85.7%, respectively. Both objective and subjective postoperative voice and swallowing function tests were within normal limits in more than 90% of the patients. Conclusion E-TOS is an effective, safe, low-cost, and minimally invasive transoral surgery for Tis-selected T3 pharyngolaryngeal cancer; it also preserves postoperative voice, larynx, and swallowing function.

Correlation of Nasal Mucosal Temperature and Nasal Patency—A Computational Fluid Dynamics Study

alexandrossfakianakis shared this article with you from Inoreader Correlation of Nasal Mucosal Temperature and Nasal Patency—A Computational Fluid Dynamics Study via The Laryngoscope This study examines the role of nasal mucosal temperature in the perception of nasal patency using in vivo and computational fluid dynamics measurements. We found that lower nasal mucosal temperature and higher heat flux anteriorly correlate with a perception of improved unilateral nasal patency in healthy individuals. Objectives Recent evidence suggests that detection of nasal mucosal temperature, rather than direct airflow detection, is the primary determinant of subjective nasal patency. This study examines the role of nasal mucosal temperature in the perception of nasal patency using in vivo and computational fluid dynamics (CFD) measurements. Methods Healthy adult participants completed Nasal Obstruction Symptom Evaluation (NOSE) and Visual Analogue Scale (VAS) questionnaires. A temperature probe measured nasal mucosal temperature at the vestibule, inferior turbinate, middle turbinate, and nasopharynx bilaterally. Participants underwent a CT scan, used to create a 3D nasal anatomy model to perform CFD analysis of nasal mucosal and inspired air temperature and heat flux along with mucosal surface area where heat flux >50 W/m2 (SAHF50). Results Eleven participants with a median age of 27 (IQR 24; 48) were recruited. Probe-measured temperature values correlated strongly with CFD-derived values (r = 0.87, p < 0.05). Correlations were seen anteriorly in the vestibule and inferior turbinate regions between nasal mucosal temperature and unilateral VAS (r = 0.42–0.46; p < 0.05), between SAHF50 and unilateral VAS (r = −0.31 to −0.36; p < 0.05) and between nasal mucosal temperature and SAHF50 (r = −0.37 to −0.41; p < 0.05). Subjects with high patency (VAS ≤10) had increased heat flux anteriorly compared with lower patency subjects (VAS >10; p < 0.05). Conclusion Lower nasal mucosal temperature and higher heat flux within the anterior nasal cavity correlates with a perception of improved unilateral nasal patency in healthy individuals.

Extrarenal Wilms tumor with hypertension and dilated cardiomyopathy in an infant: A report of an unusual case

alexandrossfakianakis shared this article with you from Inoreader Extrarenal Wilms tumor with hypertension and dilated cardiomyopathy in an infant: A report of an unusual case via Pediatric Blood & Cancer Abstract While Wilms tumors are the most frequently detected kidney cancer type in children, extrarenal Wilms tumors (ERWTs) remain rare. This report is the first to describe hypertension and dilated cardiomyopathy in a patient with an ERWT. A 6-month-old male infant presented with an abdominal mass and paroxysmal hypertension; echocardiography revealed dilated cardiomyopathy with an ejection fraction of 34%, as well as substantially increased plasma renin activity. Pathology yielded a definitive diagnosis of ERWT. Cardiac function and blood pressure gradually returned to normal after tumorectomy. The early diagnosis of such a tumor together with efficient oncologic treatment are vital to optimal patient outcomes. View on Web

Perception of orbital epitheses evaluated with eye tracker

alexandrossfakianakis shared this article with you from Inoreader Perception of orbital epitheses evaluated with eye tracker via Journal of Prosthodontics Abstract Purpose Orbital epitheses replace a missing eyeball and surrounding soft tissue. Perception of epithesis in public gaze and the attention areas on the face are of interest. This study aimed to examine the differences in perception of orbital epitheses by prosthodontists, dentistry students, and laypeople with an objective evaluation tool that utilized eye-tracking technology. Materials and methods Twenty-four frontal facial images of 12 patients who had orbital epitheses were viewed by 81 observers (prosthodontists, dentistry students, laypeople) in random order for 5 seconds each. Gaze data were analyzed. Kruskal-Wallis H test with Bonferroni correction was used to compare parameters in groups and areas of interest. Results First fixation duration at the mouth for symmetrical images were 0.30, 0.28, and 0.25 seconds for prosthodontists, students, and laypeople, respectively. Fixation duration at mouth for the laypeople (0.27s) was shorter than students (0.29s) and prosthodontists (0.31s) at symmetrical images. Time to the first fixation to epithesis, nose, and eye was significantly lower than the forehead and mouth for all groups. Fixation count at epithesis was 6.36 for prosthodontists, 5.64 for students, and 5.34 for laypeople. Conclusion Eyes were of most significant interest for all observer groups in symmetrical images. Individuals dealing with dentistry, especially prosthodontists, paid more attention to the mouth region along with the eyes in symmetrical images, considering fixation duration and fixation count. Attention directed to epithesis by all groups was verified with objective and measurable criteria. Prosthodontists' attention to epithesis and mouth was evident considering the four parameters measured. This article is protected by copyright. All rights reserved View on Web
