Correlation of Glottic Gap and Voice Impairment in Presbyphonia.

OBJECTIVE/HYPOTHESIS: The objective of this study was to investigate the glottic gap area as a significant marker for the severity of presbyphonia as it relates to patient-reported outcome measures (Voice Handicap Index-10 [VHI-10]) and stroboscopic findings. STUDY DESIGN: Retrospective case-control study conducted in an academic tertiary voice center. METHODS: Patients seen at a tertiary voice clinic who were diagnosed with presbyphonia without other organic laryngeal pathology from January 2014 to December 2017 were included. Clinical data and laryngeal videostroboscopy videos were collected. Still images at the point of vocal process approximation during adduction were captured, and the glottic gap area was measured using ImageJ. These were compared to a control cohort. Correlations were made using Wilcoxon rank sum test, Mann-Whitney U test, and Pearson correlation coefficients. RESULTS: Thirty-three patients were included. Inter-rater reliability of glottic area measurement was strong (intraclass correlation coefficient = 0.73, P < .001). Compared to controls, presbyphonia patients had a larger glottic gap area (P < .001) and greater open-phase quotient on laryngeal videostroboscopy (P < .001). Larger glottic gap area did not correlate with patient-reported vocal function as measured by VHI-10 (P = .79) and did not correlate with presence of secondary muscle tension dysphonia (P = .99). In the presbyphonia cohort, the glottic gap area did not correlate with age (P = .29). CONCLUSIONS: Glottic gap area at the point of vocal process approximation during phonation can be reliably measured. Patients with presbyphonia have a larger glottic gap area and greater open-phase quotient on stroboscopy, but these do not correlate with patient-reported voice impairment or the presence of secondary muscle tension dysphonia (MTD). These data suggest that dysphonia severity in presbyphonia is not fully explained by a glottic gap or secondary MTD alone. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:1594-1598, 2021.

Guideline Adherence and Hearing Outcomes of Sudden Sensorineural Hearing Loss in the Military Health System.

INTRODUCTION: The American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guideline (CPG) proposes several treatment recommendations regarding sudden sensorineural hearing loss (SSNHL). The treatments for this disorder have been controversial and remain varied. We sought to determine CPG adherence and hearing outcomes of SSNHL within the Military Health System (MHS). MATERIALS AND METHODS: This was a retrospective case series with chart review of the MHS's electronic medical record. Patients with SSNHL (n = 112) were treated between March 1, 2012 and September 30, 2015. Clinical improvement was defined as a 20-dB improvement in pure tone averages or a 20% increase in word recognition scores. RESULTS: Oral steroids were used in 63 (56%) patients, intratympanic (IT) steroids were utilized in 11 (10%) patients, and combination therapy was used in 38 (34%) patients. Average pure tone averages improvements with oral steroids, IT steroids, and combination therapy were 31.2 dB (95% CI, 24.4-38.0), 13.4 dB (95% CI, 0.4-29.6), and 17.3 dB (95% CI, 9.32-25.3), respectively. Average word recognition scores improvements with oral steroids, IT steroids, and combination therapy were 29.64% (95% CI, 19.5-39.7), 14.43% (95% CI, -8.32 to 45.3), and 18.48% (95% CI, 5.48-31.5), respectively. Clinical improvements with oral steroids, IT steroids, and combination therapy were 65, 46, and 50%, respectively. CONCLUSION: The MHS is uniquely positioned to evaluate adherence to CPGs on a national and international level given the robust and standardized electronic medical record. Areas identified for improvement include more timely initiation of treatment, standardization of IT steroid dosing, more accurate coding for diagnosis and treatment, and standardization of audiology evaluation.

Sudden Sensorineural Hearing Loss in the Department of Defense.

Objective The American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guideline (CPG) proposes recommendations regarding sudden sensorineural hearing loss (SSNHL). SSNHL is managed by primary care, emergency medicine, and otolaryngology providers in the Department of Defense (DoD). However, their adherence to this CPG is unknown. We sought to determine provider compliance and identify areas for improvement. Study Design Case series with chart review. Setting DoD's electronic medical record. Subjects and Methods Patients with SSNHL (N = 204) were treated between March 1, 2012, and September 30, 2015. Time from onset of symptoms to evaluation by primary care, emergency department, audiology, and otolaryngology providers and treatments were analyzed. Results The average interval from onset of symptoms to evaluation by a primary care or emergency department provider was 4.86 days (95% CI, 3.46-6.26). Time from presentation to ear, nose, and throat and audiologic evaluation was 15.26 days (95% CI, 12.34-18.20) and 14.16 days (95% CI, 11.31-17.01), respectively. Diagnostic workup included magnetic resonance imaging (n = 150, 73.5%), computed tomography (n = 28, 13.7%), and laboratory testing (n = 50, 24.5%). Oral steroids were used in 137 (67.2%) patients, with 78.8% treated with the recommended dose. Intratympanic steroids were utilized in 65 (31.9%) patients, with variable dosing. Conclusion The DoD is uniquely positioned to evaluate adherence to CPGs on national and international levels given the robust and standardized electronic medical record. Areas of improvement include timely identification of SSNHL with rapid referral to ear, nose, and throat and audiology providers; minimizing unnecessary imaging, laboratory testing, and medications; and correct dosing of oral and intratympanic steroids.
