Risk of fibromyalgia in patients with primary muscle tension dysphonia: a possible local manifestation of a musculoskeletal systemic disorder.

OBJECTIVE: To investigate the risk of fibromyalgia in patients with primary muscle tension dysphonia. METHODS: A retrospective review was conducted of patients with primary muscle tension dysphonia, diagnosed based on history of dysphonia with evidence of laryngeal muscle tension on examination. Fibromyalgia was assessed using the Fibromyalgia Rapid Screening Tool ('FiRST'). RESULTS: Fifty patients were enrolled: 25 with primary muscle tension dysphonia (study group) and 25 matched controls. The mean age of the study group was 50.7 ± 15.2 years versus 49.5 ± 18.6 years for the controls, with a male to female ratio of 3:2 for both groups. Fifty-six per cent tested positive for fibromyalgia in the study group versus 4 per cent in the controls (p < 0.001). The mean Voice Handicap Index 10 score in the study group was significantly higher for those who screened positive for fibromyalgia compared to those who screened negative. There was a positive, strong point-biserial correlation between Fibromyalgia Rapid Screening Tool and Voice Handicap Index 10 scores (r = 0.39; p = 0.09). CONCLUSION: These results suggest that fibromyalgia is a significant co-morbid condition in primary muscle tension dysphonia.

Self-reported symptoms of laryngopharyngeal reflux using the reflux symptom score in patients with obstructive sleep apnea syndrome.

BACKGROUND: Obstructive sleep apnea (OSA) is associated with many chronic diseases among which is laryngopharyngeal reflux disease (LPRD). OBJECTIVE: To investigate the prevalence of laryngopharyngeal reflux (LPR)-related symptoms in patients with OSA using the Reflux Symptoms Score (RSS) and Reflux Symptom Index (RSI). METHODS: The medical records and video-recordings of patients with OSA who presented to a tertiary referral center were reviewed. The diagnosis of OSA was made using the STOP-BANG questionnaire and/or polysomnography. The prevalence of LPR-related symptoms was assessed using both the RSS and RSI questionnaires. RESULTS: Thirty-nine patients were included in this study. Twenty-seven patients (69.2%) had a positive RSS in comparison to only 7 (17.9%) using the RSI (p = .052). Subgroup analysis of those who had polysomnography (n = 24) showed that 18 patients (75%) had a positive RSS in comparison to only 5 patients (20.8%) using the RSI. Patients in the high-risk category for OSA were also found to have a higher prevalence of LPR-related symptoms using both the RSS and RSI questionnaires in comparison to those in the lower risk categories. CONCLUSION: The results of this investigation indicate that the prevalence of LPR-related symptoms is higher using the RSS in comparison to the RSI.

Mucormycosis: A 14-Year Retrospective Study from a Tertiary Care Center in Lebanon.

Mucormycosis (MCM) is a serious invasive fungal disease (IFD) that is associated with high mortality, particularly in immunocompromised patients. A global surge in MCM cases was reported with the COVID-19 pandemic. We analyzed all recorded cases of MCM at the American University of Beirut Medical Center (AUBMC), a tertiary care center in Lebanon, over 14 years. We aimed to identify the incidence, seasonal variation, clinical characteristics of the patients, and predictors of mortality. We conducted a retrospective chart review between 1 January 2008 and 1 January 2023. All patients with proven or probable MCM were included in the study. Proven or probable MCM was defined by positive histopathology and/or positive cultures. A total of 43 patients were identified as having MCM. Their median age was 53 years, and the majority were males (58.1%). Most of the cases were diagnosed in the autumn season. In total, 67.4% of the patients had hematological malignancies (HMs), and 34.9% had uncontrolled diabetes mellitus (DM). The most common site of involvement was rhino-orbital-cerebral MCM (ROCM) (74%). The annual cases of MCM per 100,000 patient days increased markedly during the years of the COVID-19 pandemic (from 0 to 4.4 cases/100,000 patient days to 7.5 cases/100,000 during 2020 and 2021). Liposomal amphotericin (Ampho) B was used as a first-line agent in most of the patients (86%). The median duration of total in-hospital antifungal therapy was 21 days and 51.2% of the patients received step-down therapy with azoles. Surgical debridement and isolated ROCM were significantly associated with survival (p-value: 0.02 and <0.001, respectively). All-cause mortality was 46.7%, with chronic renal disease being significantly associated with mortality (p-value < 0.05). The incidence of MCM has been increasing at our institution, particularly since the COVID-19 pandemic. Early diagnosis, treatment, and surgical debridement improve patient outcomes and overall survival.

Patient tolerance in office-based blue laser therapy for lesions of the vocal folds: Correlation with patients' characteristics, disease type and procedure-related factors.

Objective: To report patient tolerance in office-based blue laser therapy for vocal fold lesions. Methods: A retrospective review of the medical records of patients who underwent office-based blue laser therapy for lesions of the vocal folds between November 2021 and February 2023 was conducted. A total of 48 patients were included. Patient tolerance was assessed using the Iowa Satisfaction with Anesthesia Scale (IOWA). Patient tolerance was analyzed in relation to patients' demographic characteristics, disease type and severity, and procedure-related factors. Results: The mean tolerance score of the study group was 1.51 ± 1.1. There was a significant difference in the mean tolerance score between smokers and non-smokers (p = .038). Patients with vocal fold cyst (n = 3) had the highest mean tolerance score followed by patients with vocal fold polyps (n = 15). There was a nonsignificant difference in the mean tolerance score between benign lesions of the vocal folds and leukoplakia. Patients with lesions extending to more than half the vocal fold had less tolerance than those with lesions limited to less than half the vocal fold (1.91 vs. 1.27, p value .041). There was a moderate and significant negative correlation between vocal fold movement VAS, swallowing VAS, and tolerance score. The mean total duration of the procedures was 10.38 ± 4.8 min. There was a mild negative correlation between the duration of the procedure and tolerance. Conclusion: Office-based blue laser therapy for vocal fold lesions is a well-tolerated procedure. Patient should be instructed how to breathe quietly and avoid swallows to improve tolerance to surgery. Level of Evidence: 4.

Office-Based Laser Therapy for Vocal Fold Cyst: A Promising Alternative Therapy Using the 445 nm Blue Laser.

Vocal fold cysts are benign lesions commonly encountered in laryngology practice. They are traditionally classified as mucus retention cysts and epidermoid cysts. The mainstay treatment is surgical excision with diligent dissection of the cyst wall. The authors of this manuscript report a series of two cases of vocal fold mucous retention cysts and one case of vocal fold pseudocyst treated with the blue laser (Wolf TruBlue 445 nm; A.R.C. Laser Company) in an office setting. All three cases had complete regression of the lesion with improved glottic closure and mucosal waves during phonation. The disease regression was associated with a decrease in the VHI-10 score, perceptual voice evaluation scores, and acoustic perturbation parameters. There was also an increase in maximum phonation time in all three cases. The authors advocate office-based blue laser therapy for vocal fold cysts as a promising treatment modality, particularly in patients at high risk for general anesthesia. Nevertheless, the possible increased risk of vocal fold scarring given the lack of binocular microscopic examination should not be underestimated. A larger study is needed to cast more information on the surgical outcome and long-term effects of blue laser therapy in the management of vocal fold cysts.

Prevalence of Laryngeal Muscle Tension in Patients With Obstructive Sleep Apnea.

OBJECTIVE/HYPOTHESIS: To determine the prevalence of laryngeal muscle tension in patients with obstructive sleep apnea (OSA). STUDY DESIGN: Retrospective case-control. METHODS: A total of 75 patients were included in this study. These were divided into a study group with a history of OSA (n = 45), and a control group with no history of OSA matched according to age and gender (n = 30). The risk of OSA was assessed using the STOP-BANG questionnaire. Demographic data included age, gender, body mass index, smoking, history of snoring, history of use of continuous positive airway pressure, and history of reflux disease. Symptoms such as hoarseness, throat clearing/cough, and globus sensation were also noted. The video recordings of the flexible nasopharyngoscopy of both groups were analyzed for the presence or absence of four laryngeal muscle tension patterns (MTPs). RESULTS: Twenty-five patients of the study group (55.6%) had signs of laryngeal muscle tension on laryngeal endoscopy compared to nine in the control patients (30%) (P = 0.029). The most common MTP observed in the study group was MTP III (n = 19), followed by MTP II (n = 17). Laryngeal muscle tension was more prevalent in patients of the intermediate and high-risk categories compared to those of the low-risk category (73.3% and 62.5% vs 28.6%, respectively) (P = 0.042). Patients with at least one MTP had more dysphonia and throat clearing than patients without any MTP. CONCLUSION: Patients with a history of OSA have a higher prevalence of laryngeal muscle tension in comparison to subjects with no history of OSA. Moreover, patients at high risk of OSA have a higher prevalence of laryngeal muscle tension than those at low risk of OSA.

Office-Based Blue Laser Therapy for Vocal Fold Leukoplakia: A Preliminary Report of 12 Cases.

Objective: To report the efficacy of office-based blue laser therapy for vocal fold leukoplakia. Study Design: A retrospective case series. Setting: A tertiary care center. Methods: A retrospective chart review of patients with vocal fold leukoplakia who underwent office-based blue laser therapy between July 2019 and October 2022 was conducted. The video recordings of their laryngeal examination and their voice evaluation were analyzed before and after surgical intervention. Results: A total of 10 patients, eight with unilateral disease and 2 with bilateral disease, were included in this study. In total, 12 vocal folds with leukoplakia were treated. Nine had a single session and 3 had 2 sessions due to incomplete regression of the lesion after the first laser therapy session. Following treatment, 9 regressed completely (75%) and 3 regressed partially (25%). The mean Voice Handicap Index-10 (VHI-10) score decreased significantly from 15.4 ± 12.9 preoperatively to 3.8 ± 2.86 after surgery (p = .023). There was a statistically significant decrease in the means of grade, roughness, breathiness, asthenia, and strain (p < .05). There was also a statistically significant decrease in the jitter and shimmer percent (p = .008 and p = .048, respectively) and a significant increase in the maximum phonation time from 9.63 ± 3.83 to 13.54 ± 5.92 seconds (p = .039). Conclusion: This preliminary study indicates that office-based blue laser therapy is an effective treatment modality for vocal fold leukoplakia.

Office-based blue laser therapy for dyspnea in patients with type 3 Reinke's edema.

PURPOSE: To investigate the effectiveness of in-office blue laser therapy on dyspnea in patients with type 3 Reinke's edema. METHODS: The medical records and video-recordings of patients with Reinke's edema type 3 who had undergone office-based blue laser therapy between March 2022 and January 2023 were reviewed. The primary outcome measures assessed before and after surgery were dyspnea severity, risk of obstructive sleep apnea (OSA), and disease regression. The severity of dyspnea was measured using the Dyspnea Severity Index (DSI), the risk of OSA was assessed using the STOP-BANG questionnaire, and disease regression was assessed by reviewing the laryngeal examination before and after surgery. The Voice Handicap Index-10 (VHI-10) was used as a secondary outcome measure. RESULT: A total of 10 patients were included. The mean age of the study population was 58.9 ± 4.2 years. The male-to-female ratio was 2:3. In total, 20 vocal fold lesions were treated among which 18 were reviewed. Eight lesions regressed completely and 10 partially. There was a statistically significant drop in the mean score of DSI after surgery (16.1 ± 10.2 pre-operatively vs 2.3 ± 2.3 post-operatively, p-value < 0.001). The mean STOP-BANG score decreased from 4.8 ± 1.47 to 3.1 ± 1.28 (p-value = 0.001). There was also a significant improvement in VHI-10 score (22.7 ± 7.0 vs 4.4 ± 5.6, p-value < 0.001). CONCLUSION: Office-based blue laser therapy offers a safe and effective treatment for shortness of breath in patients with type 3 Reinke's edema.

Office-Based Laser Therapy in Vocal Fold Polyps: A Systematic Review and Meta-Analysis.

OBJECTIVES: To analyze voice outcomes and lesion regression in patients with vocal fold polyps treated in-office using lasers. STUDY DESIGN: Systematic review and meta-analysis. METHODS: The search was performed in the Medline, Embase, and Cochrane databases using the preferred reporting items for systematic review and meta-analyses framework. There were no limitations to the year of publication and the search included studies looking at voice outcomes and lesion evolution of in-office laser treatment for vocal fold polyps measured through voice-handicap index, GRB, acoustic analysis or aerodynamics measures. Risk of bias was assessed using Cochrane's ROBINS-I tool for observational studies. Data analysis was performed SPSS software with a significance level of 5%. RESULTS: We identified 167 articles, 10 of which met the inclusion criteria and were analyzed. The total number of participants was 242. Meta-analysis showed significant improvement in voice handicap index-10 scores (95% CI, [0.86; 1.45]) and decrease in GRB score (95% CI, [1.09; 4.13]) after in-office laser therapy. It also showed significant improvement in percent shimmer (95% CI, [0.26; 1.01]), and significant increase in maximum phonation time (95% CI, [-0.92; -0.18]). CONCLUSIONS: Laser therapy an outpatient office setting is a reliable alternative to classical phono-microsurgery. Results show Office-based laser therapy of vocal fold polyps results in a significant improvement in subjective voice outcomes measures. This subjective improvement in voice quality is associated with partial or complete disease regression on laryngeal examination and an increase in maximum phonation time.

The Added Value of Steroid Injection Following Office-based Blue Laser Therapy of Benign Lesions of the Vocal Folds; Short-Term Effect in a Cohort of 43 Patients.

OBJECTIVES: To investigate the added value of steroid injection following office-based blue laser therapy of benign lesions of the vocal folds. STUDY DESIGN: Retrospective cohort analysis. METHODS: The medical records and video-recordings of patients with benign lesions of the vocal folds who underwent office-based blue laser therapy in a tertiary referral center between February 2020 and October 2022 were reviewed. Patients were divided into two subgroups, those who underwent office-based blue laser therapy alone (n = 23) and those who underwent office-based blue laser therapy with steroid injection (n = 19). Disease regression and voice outcome measures included Voice Handicap Index-10 score, perceptual voice evaluation using the GRB grading, jitter, shimmer, noise to harmonic ratio, voice turbulence index, and maximum phonation time were reviewed. RESULTS: A total of 42 patients were included. The mean age was 54.7 ± 10.1 years. Lesions included polyps (n = 21), Reinke's edema (n = 19), and cysts (n = 2). There was partial or complete disease regression in all patients who presented for follow-up (n = 37). In patients who underwent blue laser therapy alone (n = 19), 42.1% had complete regression and 57.9% had partial regression. In those who underwent blue laser therapy followed by steroid injection (n = 18), 77.7% had complete disease regression and 22.3% had partial regression. The difference in disease regression between the two subgroups was statistically significant (P = 0.027). The decrease in the mean Voice Handicap Index-10 score was also statistically significant with a higher mean being noted in the subgroup who underwent blue laser therapy followed by steroid injection (-10.5 ± 6.9 vs. -17.3 ± 11.8, P = 0.031). There was no significant difference in the decrease in the perceptual evaluation scores nor in the decrease in jitter, shimmer, noise to harmonic ratio, and voice turbulence index between the two subgroups. There was also no significant increase in the maximum phonation time. CONCLUSION: Steroid injection after blue laser therapy improves disease regression and voice outcome of laser therapy.

Office-based Blue Laser Therapy of Vocal Fold Polyps: A Cohort of 18 Patients: Blue Laser Therapy of Vocal Fold Polyps.

OBJECTIVE: To investigate the effect of office-based blue laser therapy of vocal fold polyps on voice. METHODS: The medical records and video recordings of patients who underwent office-based laser therapy in a tertiary referral center between February 2020 and May 2020, and May 2021 and October 2022 was conducted. Only patients with vocal fold polyps who had undergone office-based blue laser therapy were included. The voice was evaluated before and after surgery using the Voice Handicap Index-10 (VHI-10), GRB perceptual evaluation, acoustic analysis, and maximum phonation time. RESULTS: A total of 18 patients were included. The mean age of the study group was 52.5 ± 11.94 years. The male-to-female ratio was 2:1. Ten patients of the total group (53.6%) had hemorrhagic polyps and the most common site was the mid-third of the vocal fold. All patients who presented for follow-up (n = 15) had partial or complete regression of the lesion (4 and 11, respectively). There was a significant decrease in the mean score of VHI-10 (17.6 ± 9.97 vs. 4.27 ± 5.76, p < 0.001) and in the means of grade of dysphonia (2.0 ± 0.73 to 0.5 ± 0.63, p < 0.001), roughness (1.88 ± 0.81 to 0.44 ± 0.51, p < 0.001) and breathiness (0.81 ± 0.75 to 0.13 ± 0.34 p < 0.001). There was also a marked decrease in the perturbation parameters (jitter and shimmer) and a significant increase in the MPT from 10.66 ± 4.22 s to 14.26 ± 6.26 s (p = 0.028). CONCLUSION: Office-based blue laser therapy is an effective treatment modality in patients with vocal fold polyps. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:2712-2718, 2023.

OBJECTIVE: To analyze voice outcomes and lesion regression in patients with Reinke's edema treated in the office with lasers. STUDY DESIGN: Systematic review and meta-analysis METHODS: The search was performed in the Medline, Embase, Medline, Cochrane, and Google Scholar databases using the PRISMA framework. There were no limitations to the year of publication and the search included studies looking at voice outcomes and lesion evolution of in-office laser treatment for Reinke's edema measured through voice-handicap index, acoustic analysis or aerodynamics measures. Risk of bias was assessed using Cochrane's ROBINS-I tool for observational studies. Data analysis was performed SPSS software with a significance level of 5%. RESULTS: The initial search identified 650 articles, 6 of which met the inclusion criteria and were analyzed. The total number of participants was 58. Meta-analysis showed significant improvement in VHI-10 scores after in-office laser therapy (95% CI, [-1.46; -0.75]). It also showed significant improvement in jitter, significant increase in fundamental frequency (95% CI, [0.52; 1.71]) and significant decrease in lesion size (95% CI, [-2.03; -0.35]). CONCLUSION: Office-based laser therapy is a reliable alternative to the traditional phono-microsurgery performed in the operating room. Patients show significant improvement in voice outcomes and laryngeal examination.

Un-sedated Office-Based Application of Blue Laser in Vocal Fold Lesions.

INTRODUCTION: Office-based laser procedures in laryngology have gained a lot of popularity in the last decade with the use of the KTP, PDL and Thulium lasers. Preliminary investigations currently report on the use of the 445 nm wavelength Blue laser for the treatment of various laryngeal pathologies, given its dual photoangiolytic and cutting properties. OBJECTIVE: We aim to investigate the safety and efficacy of the Blue laser for the treatment of vocal fold lesions. METHODS: This is a retrospective chart review of eleven patients with a variety of vocal fold lesions (polyps, Reinke's edema, papilloma, and leukoplakia), that underwent un-sedated office-based treatment using the 445 nm blue laser. The primary outcome was to compare preoperative to postoperative Voice Handicap Index (VHI-10) score and self-reported voice improvement using a visual analog scale (VAS). We also compared fiberoptic laryngeal examination before and after treatment. RESULTS: Eleven un-sedated office-based procedures using the blue laser were performed. There was improvement in the mean VHI-10 score (n = 8) with a decrease from 15.13 ± 8.77 to 3.50 ± 3.46 (P= 0.015). Similarly, the mean VAS score (n = 7) decreased from 6.14 ± 1.21 to 1.71 ± 1.60 (P< 0.003). All patients had a complete or partial regression of the vocal fold lesions on fiberoptic laryngeal examination. None of the patients had complications after the procedure. CONCLUSION: Blue laser therapy can be suggested as a safe and effective alternative treatment modality in office-based laryngology procedures for a variety of vocal fold lesions. A larger series is needed to better validate the efficacy of this laser as a new treatment modality.

Diagnostic Yield of Office-Based Laryngeal Biopsy in Patients With Leukoplakia; A Case Study With Review of the Literature.

OBJECTIVE: To review the authors experience in un-sedated office-based biopsies of patients with vocal fold leukoplakia and to review the literature. MATERIAL AND METHOD: A retrospective review of 29 patients was conducted. RESULTS: A total of 41 office-based procedures were performed (eight patients had bilateral vocal fold lesions and four patients had the procedure performed twice). In 26 out of the 41 biopsies, the pathology revealed benign lesion. In eight cases, the pathology showed dysplasia (four high-grade and four low-grade). Seven biopsies revealed squamous cell carcinoma. Five patients underwent suspension micro-laryngoscopy for definitive diagnosis. Four of whom had a change in their diagnosis. CONCLUSION: Un-sedated office-based biopsy of vocal fold leukoplakia is an alternative to suspension microlaryngoscopy in case of carcinoma or nonmalignant lesions.

Tolerance of Patients Using Different Approaches in Laryngeal Office-Based Procedures.

OBJECTIVE: To evaluate the tolerance, overall experience, procedure discomfort, and patient anxiety using different routes in office-based laryngeal procedures. SUBJECTS AND METHODS: We performed a retrospective analysis of patients undergoing office-based laryngeal procedures for the treatment or diagnosis of laryngeal lesions via transnasal, transoral, or percutaneous routes. Tolerability, overall experience, procedure discomfort, and patient's anxiety were evaluated and reported on a custom scale over 5. RESULTS: A total 178 procedures performed on 154 patients were reviewed. The video-recordings and data on 15 procedures were missing. A total of 163 procedures were included in this study. These were stratified as follows; 128 procedures via the transnasal fiberoptic approach, 16 procedures via the transoral fiberoptic approach, and 19 procedures via the percutaneous approach. There was no significant difference in the mean score of overall experience across the three different approaches (P= 0.926). The mean overall experience score for the transnasal approach was 1.85, vs 1.93 and 1.94 for the transoral and percutaneous approach, respectively. Similarly, there was no significant difference in the mean score of tolerability across the three different approaches. The mean tolerability score was 1.68 using the transnasal approach, compared to 1.6 using the transoral approach, and 1.84 using the percutaneous approach (P= 0.77). Anxiety scores, and procedure discomfort scores did not differ either among the three groups (P= 0.138 and P= 0.656, respectively). CONCLUSIONS: There was no significant difference in tolerability, anxiety, procedure discomfort, and overall experience regarding the different approaches employed.

Regional versus general anesthesia in knee arthroplasty in patients with different classes of BMI: A matched analysis of the NSQIP database.

BACKGROUND: Knee arthroplasty for knee arthritis is a commonly performed surgery yielding excellent functional results and good pain relief. It is associated with post-surgical complications according to the type of anesthesia and BMI class. METHODS: The National Surgical Quality Improvement Project database for the years 2005-2012 for patients >18 years of age who underwent knee arthroplasty, condyle and plateau, medial and/or lateral compartment. The surgical site complications, bleeding occurrences necessitating transfusion, unplanned readmissions, and mortality stratified according to anesthesia type and BMI class over a period of 30-days were examined. RESULTS: A total of 78,275 patients were included for analysis; regional anesthesia showed a consistent protective effect from surgical site complications more prominent with increasing obesity class with respective ORs and their corresponding 95% CI for pre-obesity, class I, II, and III obesity being 0.95 [0.89-1.09], 0.75 [0.68-0.83], 0.64 [0.57-0.72], and 0.61 [0.54-0.7]. CONCLUSIONS: Higher BMI values are a protective factor for the risk of bleeding requiring transfusion in patients undergoing total knee arthroplasty. Moreover, regional anesthesia is the preferred choice of anesthesia as well if postoperative complications are considered. A significant decrease in the rate of post-operative blood transfusions was seen in patients with high BMI and regional anesthesia.

Unsedated Office-Based Blue Laser Therapy in Female Patients With Reinke's Edema: A Retrospective Review of 8 Cases.

OBJECTIVES: To report on the outcomes of unsedated blue laser therapy in female patients with Reinke's edema. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective chart review of female patients undergoing unsedated office-based blue laser treatment of Reinke's edema between February 2020 and March 2022 at the Hamdan Voice and Swallowing Unit at the American University of Beirut Medical Center in Beirut, was conducted. Patients were assessed before and after the procedure with a follow-up interval of 3-6 weeks. Demographic data included age, history of smoking and grade of Reinke's edema. Voice outcome measures included the Voice Handicap Index-10 questionnaire, perceptual evaluation (GRBAS scale), acoustic analysis and maximum phonation time. Vocal fold lesions were evaluated using indirect laryngeal endoscopy. RESULTS: A total of eight patients were reviewed. The mean age was 59.63 ± 7.98 years. One patient was lost to follow-up. We report on a total of 10 Reinke's edema lesions treated with the blue laser. There was a significant decrease in the mean VHI-10 score (14.86 ± 5.84-6.71 ± 7.32; P < 0.01) as well as in the means of three perceptual evaluation parameters (G, R, B; P < 0.05). There was also a nonstatistically significant increase in the mean fundamental frequency and habitual pitch. Laryngeal examination showed complete regression in 50% of the lesions, and partial regression in the remaining 50%. CONCLUSIONS: Office-based blue laser treatment of Reinke's edema under local anesthesia can be considered an effective treatment modality as evidenced by improvement in post-procedure voice outcome measures.

Prevalence of Laryngopharyngeal Symptoms in Patients With Gastroesophageal Reflux Disease Refractory to Medical Therapy Undergoing Esophagogastroduodenoscopy.

OBJECTIVE: Casting more information on the link between GERD and LPR by investigating the prevalence of laryngopharyngeal symptoms in patients with severe GERD refractory to medical treatment. DESIGN: Prospective Study METHODS: Fifty patients with typical GERD symptoms presenting for EGD were recruited. All patients filled the GERD-Health-Related Quality of Life (HRQL) questionnaire and were screened for LPR using the Reflux Symptom Score questionnaire. All patients were also evaluated for the presence of hiatal hernia, esophagitis, inlet patch, gastritis (erosive vs. non erosive), polyps, intestinal metaplasia and or Helicobacter pylori infection. Laryngeal images were taken during EGD and evaluated using the Reflux Sign Assessment (RSA). RESULTS: A total of 50 patients were recruited for this study. The prevalence of heartburn was the highest (90%). The mean score of GERD-HRQL was 30.76±15.09. The mean RSS score was 70.96±46.08. Laryngeal examination was documented in 49 patients. the most common finding was edema (34.7%) followed by redness (28.6%). The mean RSA score for the total group was 21.15±8.04. There was a strong correlation between RSS score and GERD-HQRL score. There was no significant correlation between the RSS and any of the EGD findings (P > 0.05). There was no significant correlation between RSA and GERD-HRQL scores or any of the EGD findings (P > 0.05). However, there was a significant correlation between total RSA and RSS scores (rho=0.287, P = 0.04). CONCLUSION: The suggested high prevalence of LPRD should alarm the treating physician to the need for a thorough otolaryngologic examination in patients presenting with severe GERD, particularly those in whom the LPR symptoms may be masked by the typical symptoms of GERD.

The Impact of Masking Habits on Voice in a Sub-population of Healthcare Workers.

OBJECTIVE: To evaluate the impact of face masks on voice in a sub-population of healthcare workers, namely residents, medical students, and nurses, during the COVID-19 era. MATERIALS AND METHODS: A cross-sectional study was conducted in a large tertiary care center where a 23-items web-based questionnaire was conveyed to sub-population of healthcare professionals, namely residents, medical students, and nurses. The questionnaire included demographic data, type, and duration of mask use. Voice outcome measures included the Voice Handicap Index (VHI)-10 questionnaire and the visual analogue scale for vocal effort and vocal fatigue. RESULTS: A total of 178 participants answered the survey. One third had an abnormal score on the VHI-10 questionnaire, one third reported moderate to severe vocal fatigue, and 45% of the participants had moderate to severe vocal effort based on a visual analogue scale score. There was a significant association between the type of mask used and vocal fatigue (P = 0.044). No significant association was seen between the duration of mask used and the different voice outcome measures. CONCLUSION: Masking habits during the COVID-19 pandemic were associated with a high prevalence of vocal fatigue, effort and abnormal VHI-10 score among residents, medical students, and nurses.
