The Risk of Obstructive Sleep Apnea in Patients with Primary Muscle Tension Dysphonia.

To explore the risk of obstructive sleep apnea (OSA) in patients with primary muscle tension dysphonia (MTD). The medical records of patients diagnosed with primary MTD between November 2021 and March 2023, were reviewed. The risk of having OSA was assessed by looking at the scores of two validated questionnaires, namely the STOP-BANG questionnaire and the Berlin questionnaire. A total of 40 patients with primary MTD were enrolled in this study, including 16 females (40%) and 24 males (60%). The mean total STOP-BANG score was 3.57 ± 1.67. Seventeen of the study group had intermediate risk of OSA, and 14 had high risk, accounting for 77.5% of patients with primary MTD. When using the Berlin questionnaire, the mean total score was 1.65 ± 0.95, and 67.5% of the study group had a score > 2 and were at high risk of having OSA. The results of this study indicate that patients with primary MTD are at moderate to severe risk of having OSA.

Transnasal Endoscopic Injection of Botulinum Toxin in Patients with Adductor Spasmodic Dysphonia.

Introduction: Adductor Spasmodic Dysphonia (ADSD) is the most common form of spasmodic dysphonia. It encompasses various symptoms affecting voice and speech. The objective of this study is to report the management of patients with ADSD using the transnasal endoscopic approach for laryngeal Botulinum Toxin (Botox) injection. Materials and Methods: A retrospective chart review of patients with ADSD who underwent transnasal endoscopic laryngeal Botox injection was conducted. Voice outcome measures included the Voice Handicap Index-10 (VHI-10) score and the degree of speech fluency. Results: Eight patients with ADSD who underwent 20 office-based transnasal endoscopic laryngeal Botox injections were included. The most commonly injected sites were the thyroarytenoid muscle (TA) and the false vocal fold in 95% and 55% of the cases, respectively. The mean dose of injected Botox was 2.48 ± 0.55 IU in the TA muscle, and 2.14 ± 0.53 IU in the false vocal fold. The mean amount of Botox injected in the larynx was 7.16 ± 2.42 IU. The mean follow-up period was 17.7 ± 13.3 months. There was marked improvement in speech fluency in 64.7% of the cases and mild improvement in one third of the cases. Marked improvement in speech fluency was recorded in 64.7% of the cases and mild improvement in one third of the cases. The mean VHI-10 score of patients dropped significantly from 22.47±4.08 to 15±4.69 following treatment (p<0.001). Conclusions: The transnasal endoscopic approach is an effective and well-tolerated approach for laryngeal Botox injection in patients with ADSD.

Office-Based Blue Laser Therapy vs Thulium Laser Therapy for Reinke's Edema.

OBJECTIVE: To compare the treatment outcomes of patients with Reinke's edema (RE) who were treated in-office using the blue laser vs those treated in-office using the thulium laser. STUDY DESIGN: Retrospective case-control study. METHODS: The medical records and video recordings of patients who underwent office-based thulium laser therapy for RE between November 2018 and July 2019, and office-based blue laser therapy for RE between November 2023 and March 2024 in a tertiary referral center were reviewed. The primary outcome measures used in this study were the Voice Handicap Index-10 (VHI-10) score and disease regression based on the laryngeal examination performed before and after therapy. RESULTS: Twenty-two patients were included in this study. They were divided into 2 subgroups, 12 patients with 22 lesions who underwent office-based thulium therapy and 10 patients with 17 lesions who underwent office-based blue laser therapy. There was no significant difference in the decrease in the mean VHI-10 score following surgery between those treated with the thulium laser vs those treated with the blue laser (10.5 ± 13.15 vs 8.2 ± 5.98, P = 0.657). Nine out of 22 lesions (40.9%) treated with thulium laser regressed completely compared to 9 out of 17 lesions (52.9%) treated with a blue laser. The difference in disease regression between the two subgroups was not statistically significant (P = 0.455). CONCLUSIONS: Blue laser and thulium laser can be used interchangeably in-office for the treatment of RE with no significant difference in patient self-perceived improvement in voice quality and disease regression. A larger study using objective measures is warranted.

Algorithm for airway management in benign intra-tracheal lesions.

The authors have conducted a retrospective analysis based on two cases of patients with intra-tracheal pathologies who received treatment from the same surgeon at a tertiary referral center. The effective management of airways in patients with intra-tracheal lesions necessitates close collaboration between surgeons and anesthesiologists. Factors such as the size, location, rigidity of the tumor, and the remaining tracheal lumen space should be carefully considered. In situations where there is near complete obstruction of the trachea and a substantial risk of worsened respiratory function, resorting to cardiopulmonary bypass or extracorporeal membrane oxygenation is advisable. This pilot study aims at devising an algorithm for the airway management of intra-tracheal lesions, although a larger case cohort is needed to assess its applicability and effectiveness.

Voice Disorders in Patients with Fibromyalgia: Case Series and Review of the Literature.

OBJECTIVE: To investigate the prevalence of phonatory disorders and their impact on quality of life in a cohort of patients with fibromyalgia (FMS), and to review the literature. STUDY DESIGN: Prospective cohort study. METHODS: All adult patients presenting to the rheumatology clinic at a tertiary referral center between January 2024 and April 2024 and diagnosed with FMS were prospectively recruited. The primary outcome measure used to screen for dysphonia was the Voice Handicap Index-10 (VHI-10). All patients were also asked to fill the Fibromyalgia Rapid Screening Tool (FiRST) and the short form of the McGill pain questionnaire (SF-MPQ). RESULTS: A total of 70 female patients were included, divided equally into a study and control group (n = 35). The mean FiRST score and the mean SF-MPQ score were significantly higher in the study group compared to the control group (6.20 ± 1.05 vs 1.26 ± 1.65) and (26.14 ± 13.16 vs 2.6 ± 4.23), respectively. There was a statistically significant difference in the mean VHI-10 score between the study group and the control group (8.51 ± 7.66 vs 0.74 ± 0.98; P < 0.001). More than one third of patients in the study group had a VHI-10 score above 11 (37.1%) compared to none in the control group (P < 0.001). There was a strong positive correlation between the VHI-10 score and the FiRST and SF-MPQ scores (r = 0.612; P < 0.001 and r = 0.794; P < 0.001, respectively). CONCLUSION: The findings suggest that two out five patients with FMS have vocal complaints that impact their quality of life. Healthcare providers need to recognize these phonatory disorders, that are often masked by other systemic manifestations of the disease.

Office-based blue laser therapy for inferior turbinate hypertrophy: a pilot study.

PURPOSE: To investigate the subjective effect of office-based blue laser therapy for inferior turbinate hypertrophy in patients with nasal obstruction. METHODS: Patients with nasal obstruction who underwent office-based blue laser for the inferior turbinate hypertrophy between October 2022 and December 2023 were included in the study. The two outcome measures used to gauge the improvement in nasal obstruction and success of surgery were the Nasal Obstruction Symptom Evaluation (NOSE) scale and the Visual Analogue Scale (VAS). Patient's level of comfort during the procedure was also rated using a 10-point VAS scale. RESULTS: A total of 14 patients were included in this study. The mean age of the study group was 41.47 ± 18.52 and the F/M ratio was 4.67. All patients reported significant improvement in nasal breathing. The mean NOSE score decreased significantly from 13.07 ± 3.89 pre-operatively to 2.64 ± 2.43 post-operatively (p = 0.002). Similarly, the mean VAS score decreased from 7.43 ± 0.85 to 2.0 ± 1.57 (p = 0.002) following surgery. The procedure was well-tolerated by all participants and the mean total score ranged from 6 to 9 with an average of 7.59 ± 1.34. CONCLUSION: Office-based blue laser therapy for inferior turbinate hypertrophy may be an effective treatment modality for nasal obstruction from the patient's perspective. Although the procedures were tolerated well with no complications noted, these results should be cautiously interpreted until studies using objective measures are conducted.

Diabetes Insipidus after Endoscopic Endonasal Pituitary Macroadenoma Resection: Correlation of Patient and Surgery-Related Risk Factors.

Purpose This article aims to identify patient- and surgery-related factors that could predict the development of postoperative central diabetes insipidus (DI). Methods This is a retrospective case-control study conducted at a single-institution tertiary referral center. Patients undergoing endoscopic endonasal skull base surgery for pituitary adenoma between November 2018 and April 2023 were recruited. The main outcome measures collected include age, gender, comorbidities, tumor type, postoperative DI, intraoperative and postoperative cerebrospinal fluid (CSF) leak, flow of CSF leak, number of layers required for repair, the use of nasal packing, and hospital length of stay. Results A total of 20 patients developed DI postoperatively. Patients' demographic and comorbidity profile did not correlate with DI development. The encounter of an intraoperative CSF leak was correlated with postop DI (chi-square (1) = 18.35, p < 0.001) with a relative risk (RR) of 2.7 (confidence interval [CI] = 1.37-5.28). The use of nasal packs was also correlated with postop DI (chi-square (1) = 10.17, p = 0.001) with a RR of 1.8 (CI = 1.15-2.87). Defects requiring a two or more layers for reconstruction also correlated with postop DI compared to single layer repairs (chi-square (1) = 12.15, p < 0.001) irrelevant of the materials used. Development of DI postop correlated with an increased hospital length of stay ( t (64) = -3.35, p = 0.001). Conclusion The physician should be careful when evaluating patients with pituitary adenomas in the postoperative period, particularly those with intraoperative CSF leak, nasal packing, and those who underwent multilayer reconstruction of the surgical defect.

Intramuscular Lipoma of the Sternocleidomastoid Muscle: A Rare Entity Revisited.

Intramuscular lipomas, typically found in subcutaneous tissue, rarely affect deeper muscular planes, especially those of the head and neck region. The following are 3 cases of intramuscular lipomas involving the sternocleidomastoid muscle. The first 2 patients presented with painless, palpable masses confirmed by diagnostic imaging as well-circumscribed intramuscular lipomas. One was treated surgically, while the other was managed conservatively with monitoring and close follow-up. The third patient reported dysphagia associated with occasional dyspnea and mild pain. The mass was identified as infiltrative lipoma and was resected surgically. Complete tumor removal with no recurrence at 6 months was observed for the first and last cases. The second case was serially followed at 3 and 6 months with no interval changes. We report the largest case series on intramuscular lipomas of the sternocleidomastoid muscle to enhance our understanding of this rare entity.

Office-Based Steroid Injection for Benign Lesions of the Vocal Folds: Case Series and Review of the Literature.

OBJECTIVES: To present the authors' experience on intralesional steroid injection (ILSI) for benign lesions of the vocal folds and a review of the literature. STUDY DESIGN: Retrospective chart review. METHODS: The medical records of patients with vocal folds nodules, polyps, Reinke's edema, laryngitis/localized edema, and vocal fold granuloma who underwent ILSI were reviewed. Disease regression was assessed by reviewing the video recordings of laryngeal endoscopy before and after surgery. Subjective and objective voice outcome measures were compared before and after office-based ILSI. RESULTS: Forty-seven patients with 81 lesions were included. The most common lesion treated was Reinke's edema followed by vocal fold nodules. All patients who presented for follow-up (n = 37) had partial or complete regression of their disease. When stratified by disease type, vocal fold polyps showed the highest percentage of complete regression (66.7%) followed by vocal fold nodules (65%). The mean voice handicap index-10 (VHI-10) score of the study group dropped from 16.63 ± 6.95 to 6.21 ± 6.09 points (P < 0.001). Patients with vocal fold polyps had the highest drop in the mean VHI-10 score by 16.66 ± 4.73 (P = 0.026). There was no significant difference in the mean acoustic and aerodynamic parameters before and after office-based steroid injection. CONCLUSIONS: ILSI is an effective treatment modality for benign lesions of the vocal folds leading to partial or complete disease regression and self-reported improvement in voice quality.

Risk of Fibromyalgia in Patients with Primary Muscle Tension Dysphonia: A Prospective Pilot Study.

OBJECTIVE: To investigate the risk of fibromyalgia in patients with primary muscle tension dysphonia (MTD) in comparison to subjects with no dysphonia. STUDY DESIGN: Prospective cohort study. METHODS: The medical records and video recordings of all patients presenting to the Voice and Swallowing unit at a tertiary referral center between October 2022 and October 2023 and who were diagnosed with primary MTD were prospectively reviewed. The risk of fibromyalgia was assessed using the "Fibromyalgia Rapid Screening Tool" (FiRST). Demographic data included age, gender, history of smoking, and history of high vocal load. The impact of dysphonia on quality of life was also analyzed using the Voice Handicap Index-10 (VHI-10). RESULTS: A total of 42 patients who had filled the FiRST questionnaire were enrolled in this study. These included 20 patients diagnosed with primary MTD and 22 healthy subjects with no history of dysphonia and normal laryngeal examination. Forty percent of the study group tested positive using the FiRST questionnaire as compared to only 9.1% in the control group. The difference between the two groups was statistically significant (P = 0.03). The risk of having fibromyalgia was 6.67 times among patients with primary MTD in comparison to controls (RR=6.67; 95% CI [1.21-36.74]). CONCLUSION: The results of this investigation indicate that the risk of fibromyalgia is significantly higher in patients with primary MTD vs controls. A holistic approach in the diagnosis and treatment of MTD is advocated.

Arytenoid Cartilage Collapse During Inhalation in Awake Patients with Intermediate/High Risk of Obstructive Sleep Apnea: A Retrospective Analysis of Sixty-Four Patients.

OBJECTIVE: To assess the prevalence of arytenoid cartilage collapse (ACC) during deep inhalation in awake patients with intermediate/high risk of obstructive sleep apnea (OSA). STUDY DESIGN: Retrospective case-control study. METHODS: The medical records and video recordings of awake flexible endoscopic examination of patients with history of OSA who presented to the sleep apnea clinic in a tertiary referral medical center between June 2022 and December 2022, were reviewed. All patients had filled the STOP-BANG questionnaire and had intermediate/high risk of having OSA. A group of patients matched by age and gender and with no history of OSA were used as controls. RESULTS: A total of 95 patients, 64 with a history of OSA and 31 with no history of OSA, were included. Among the study group, 37.5% (n = 24) had a STOP-BANG score between 3 and 4 and were considered to be at an intermediate risk of OSA while the remaining had a score more than 5 and were considered to be at high risk of OSA. There was a significant difference in the prevalence of ACC between the study group and controls (32.8% vs 12.9%, respectively, P < 0.001). CONCLUSION: The prevalence of ACC was significantly higher in patients with intermediate/high risk of OSA in comparison to healthy controls with no history of OSA. When present, ACC should raise the physician's suspicion for OSA and probably prompt further investigation such as a sleep study.

Spontaneous Oropharyngeal Bleeding Caused by Lingual Artery Pseudo-Aneurysm.

Spontaneous oropharyngeal bleeding is an uncommon but serious medical emergency mainly caused by accidental trauma or post-tonsillectomy. In extremely rare cases, it can be attributed to arterial pseudoaneurysm (PA) of head and neck vessels. The authors present the case of a young female patient presenting with recurring spontaneous oropharyngeal bleeding who was found to have a lingual artery PA on angiography. Due to the active nature of the hemorrhage and extensive blood loss, embolization of the tonsillar branch of the lingual artery was successfully performed. When evaluating patients with spontaneous oropharyngeal bleeding, one should suspect the presence of an arterial PA, especially if the bleeding recurs following initial conventional interventions.

The sensitivity of laryngeal findings in predicting high-grade dysplasia in patients with vocal fold leukoplakia undergoing office-based biopsies: A retrospective analysis of 100 cases.

Objective: To investigate the sensitivity of laryngeal findings in predicting high-grade dysplasia/carcinoma in situ (CIS) and squamous cell carcinoma (SCC) in patients with vocal fold leukoplakia. Methods: A retrospective review of the medical records and video recordings of the laryngeal examination of patients with vocal fold leukoplakia who underwent un-sedated office-based laryngeal biopsy in a tertiary referral center between January 2022 and August 2023 was conducted. Laryngeal findings included the size, surface, projection, and edges of the lesion. Vocal fold leukoplakia was classified according to the WHO as benign, low-grade dysplasia, high-grade dysplasia/CIS, and squamous cell carcinoma. Results: Seventy patients with 100 vocal fold leukoplakia were included. Size was found to have the highest sensitivity with an AUC of 0.730 (95% CI [0.618-0.842], p = 0.002) followed by surface and projection with AUCs of 0.672 (95% CI [0.548-0.795], p = 0.019) and 0.675 (95% CI [0.546-0.804], p = 0.017), respectively. Furthermore, the odds of diagnosing high-risk lesions (high-grade dysplasia/CIS and SCC) were the greatest when the lesion was large and rough (OR = 10.28; 95% CI [3.08-34.36]). Conclusion: The morphological features of vocal fold leukoplakia may assist the physician in predicting the risk of malignancy. Large and rough lesions were more likely to harbor high-grade dysplasia/CIS and SCC compared to small and smooth lesions.

Office-based blue laser therapy for vocal fold polyps and Reinke's edema: a case study and review of the literature.

PURPOSE: To report the efficacy of blue laser in the treatment of vocal fold polyps and Reinke's edema in an office setting. METHODS: The medical records and video-recordings of patients who underwent office-based blue laser therapy in a tertiary referral center for vocal fold polyps and/or Reinke's edema were reviewed. The primary outcome measures were the Voice Handicap Index-10 (VHI-10) score and disease regression. Acoustic and aerodynamic parameters were also analyzed. RESULTS: Thirty-five patients (21 with vocal fold polyps and 14 with Reinke's edema) were included and a total of 47 lesions were treated. Out of the 35 patients, 7 patients were lost for follow-up. The mean VHI-10 score dropped significantly after surgery by 17.41 ± 8.67 points (p < 0.001). The endoscopic examinations of 38 lesions were reviewed (17 vocal fold polyps and 21 Reinke's edema) before and up to 6 months after laser therapy. In the subgroup with vocal fold polyps (N = 17), there was complete disease regression in 13 and partial in 4. In the subgroup with Reinke's edema (N = 21), there was complete disease regression in 7 and partial disease regression in 14. For patients with vocal fold polyp, there was a significant decrease in shimmer and a significant increase in maximum phonation time postoperatively. For patients with Reinke's edema, there was a significant decrease in shimmer and noise-to-harmonic ratio following treatment. CONCLUSION: Office-based blue laser therapy is an effective treatment for vocal fold polyps and Reinke's edema leading to complete or partial disease regression. All patients had improvement in voice quality.

Tips and Tricks to Safely Perform an Endoscopic Endonasal Trans-Sphenoidal Pituitary Surgery: A Surgeon's Checklist.

The authors aimed to develop an extensive preoperative checklist of CT scan findings during endoscopic access to the ventral skull base and implement it in clinical practice. A comprehensive literature review was conducted to identify the radiological landmarks crucial to endoscopic skull base surgery. Four electronic databases were searched: PubMed, MEDLINE, EMBASE, and Google Scholar using search terms/keywords such as "radiological landmarks," "endoscopic skull base surgery," "CT scan," "pituitary surgery," "anatomical variations," "internal carotid," "optic nerve," "sphenoid sinus," "pneumatization," "dehiscence," and "protrusion". Inclusion criteria were limited to original articles and systematic reviews published in English, between the years 2000 and 2021, which pertained to the radiological landmarks to be identified during endoscopic skull base surgery. Full-text articles were retrieved and collated into a narrative review focused on a 12-item checklist the authors agreed upon. The mnemonic "O ROAD TO SELLA" was used to represent the checklist and include the following landmarks: Sphenoid Ostium, Sphenoid Rostrum, Onodi cells, Anatomic variations of the sphenoid sinus, Distance between the carotids, Tumor characteristics, Optic nerve dehiscence/protrusion, Septation/insertion of the sphenoid sinus, Entrance to the sellar floor, Lateral recess of the sphenoid sinus, cLinoid process pneumatization, and internal carotid Artery dehiscence/protrusion. The checklist is designed to be used by attending physicians, fellows, and residents and the authors intend to implement it into electronic medical records at the institution's medical center to monitor the outcomes of EEPS after implementation.

Effect of Vitamin D Deficiency on Voice: A Review of the Literature.

OBJECTIVE: The purpose of this study is to review the current literature on the effect of hypovitaminosis D on voice. STUDY DESIGN: Narrative review. METHODS: The literature search from electronic databases included PubMed/MEDLINE, EMBASE, SCOPUS, and Google Scholar. Search terms included voice, voice quality, voice disorders, larynx, laryngology, acoustic analysis, vitamin D, calcitriol, cholecalciferol, vitamin D deficiency, and vitamin D insufficiency. All studies on patients with vitamin D deficiency, which included subjective and objective voice assessments, were reviewed. RESULTS: A total of 39 studies were retrieved. Only four studies met the above-mentioned inclusion criteria and hence were included in this review. The total number of subjects analyzed was 466. The subjective voice outcome measures used were the Voice Handicap Index-10 (VHI-10), self-reported phonatory symptoms, and the GRBAS scale. Objective voice outcome measures included fundamental frequency, jitter, shimmer, noise-to-harmonic ratio, maximum phonation time, and dysphonia severity index. CONCLUSION: Vitamin D deficiency has no significant effect on laryngeal muscles. There was no statistically significant difference in VHI-10 score, self-reported dysphonia, perceptual voice evaluation scores, or any of the acoustic measures between those with or without vitamin D deficiency.

Effect of Diabetes Mellitus type 2 on Voice: A systematic review and Meta-analysis.

INTRODUCTION: Diabetes Mellitus type 2 is a growing health concern that affects several systems in the body among which the phonatory apparatus. Voice may be affected in view of the high prevalence of myopathy and neuropathy in diseased subjects. The authors aim to answer the following question: Does type 2 diabetes have an effect on voice? METHODS: The systematic review included search terms such as "speech, voice, larynx, glucose, diabetes, and hyperglycemia". The search strategy yielded 221 articles, only five of which satisfied the inclusion criteria. Articles were considered for inclusion using the PRISMA method. Analysis included 321 patients with type 2 diabetes mellitus and 171 controls. All studies included were case control studies except for one study which was an observational cohort. Six parameters were chosen as endpoints for the systematic review and meta-analysis: the presence/absence of voice complaints, fundamental frequency (fo), jitter, shimmer, noise to harmonic ratio (NHR) and maximum phonation time. RESULTS: There was no significant difference in the prevalence of voice complaints (i.e., hoarseness) between diabetic patients and control groups. There was also no significant difference in any of the acoustic and aerodynamic measures between patients with type 2 diabetes and controls. These findings can be ascribed the high resilience of the laryngeal muscles to the adverse effect of systemic diseases. CONCLUSION: There is no consensus in the literature that the prevalence of voice symptoms in diabetic patients is significantly higher than that reported in healthy subjects.

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.
