Assessment of Factors Impacting Long-Term Utilization of Tracheoesophageal Speech Among Laryngectomees.

OBJECTIVE(S): To evaluate complication rate and abandonment rate after tracheoesophageal puncture and to assess factors associated with these outcome measures. METHODS: Retrospective review of laryngectomy patients seen at a single academic institution between 1/1/2003 and 12/1/2018. Charts reviewed for demographics, medical comorbidities, tumor characteristics, surgical data, adjuvant treatment history, and complications related to laryngectomy or tracheoesophageal puncture. Complications were divided into minor and major. RESULTS: A total of 293 laryngectomees met inclusion criteria. Of these, 69 patients (23.5%) underwent tracheoesophageal puncture. Average follow up was 64.6 months (SD 58.3). Overall laryngectomy complication rate was 43.3%. Overall tracheoesophageal puncture complication rate was 73.9%, with 39.1% of patients having major complications and 34.8% having minor complications only. Total abandonment rate for tracheoesophageal puncture was 34.8%. No associations were seen between tracheoesophageal puncture complication or abandonment rates based on age, gender, race, or insurance status. An increased rate of laryngectomy complications was seen after primary tracheoesophageal puncture (76.5% vs 41.3%, P = .005). CONCLUSION: Tracheoesophageal puncture outcomes were similar in patients with varied demographic, medical, and treatment backgrounds. When considering timing, our findings suggest that patients should be counseled on the possibility of increased complication risk after primary tracheoesophageal puncture. In those in whom the surgeon already has concerns about wound healing, it may be prudent to avoid primary tracheoesophageal puncture. The relatively high abandonment rate emphasizes the value of this measure of tracheoesophageal puncture outcome and highlights the need for appropriate patient counseling and prospective studies assessing the decision to abandon.

The Reflux Symptom Index and Symptom Overlap in Dysphonic Patients.

OBJECTIVES/HYPOTHESIS: The Reflux Symptom Index (RSI) is a validated quality-of-life instrument that quantifies symptoms associated with laryngopharyngeal reflux (LPR). Many dysphonic patients are managed empirically for reflux. In this study, we examine responses to the RSI in patients with dysphonia attributable to a variety of pathologies. STUDY DESIGN: Retrospective cohort study. METHODS: This is an institutional review board-approved study. All patients presented to a tertiary care voice center January 2011 to June 2016 with the chief complaint of dysphonia. Patients were analyzed by 1) diagnosis and 2) treatment modality: surgery, medicine, or voice therapy (VT). Data collected included pre- and postintervention RSI and Voice Handicap Index, demographic, and clinical information. Statistical analysis was performed using SPSS. RESULTS: Five hundred forty-six dysphonic patients were included. One hundred forty required surgery, 155 were treated with VT alone, and 251 were medically managed (MM). Prior to therapy, 63.4% of surgery patients, 62.5% of VT patients, and 74.6% of MM patients had an abnormal RSI with a score greater than 13. The most common diagnosis for each group was vocal cord paresis/paralysis (surgery), vocal fold atrophy (VT), and LPR (MM). There was a statistically significant improvement in RSI after treatment for each group. CONCLUSIONS: In patients with dysphonia, pretreatment RSI scores were elevated for a variety of laryngeal pathologies. Scores often improved with directed treatment, regardless of etiology. This highlights the symptom overlap between reflux and nonreflux causes of dysphonia, and the importance of a comprehensive workup for patients with voice complaints.

The role of quality-of-life instruments in predicting voice therapy dropout.

OBJECTIVES/HYPOTHESIS: Voice therapy (VT) is essential to the successful management of voice disorders. Despite this, two-thirds of patients drop out of therapy before completion. In this study we examine whether responses to specific question items or domains from the Voice Handicap Index (VHI) are associated with VT compliance. STUDY DESIGN: Single-institution retrospective cohort study. METHODS: All patients presented to a tertiary care center between January 2011 and June 2016 with dysphonia. Patients were excluded if seen by speech language pathology (SLP) for preoperative assessment only, there was no order for therapy, or there was no documentation of therapy performed at outside facilities. Data collected included VHI responses, demographics, diagnosis, social history, and clinical exam. Patients were divided into three groups for analysis: 1) did not attend therapy, 2) partially completed therapy, or 3) completed therapy. RESULTS: Of 489 patients referred for VT, 36.2% did not attend, 36.0% partially completed VT, and 27.8% completed VT. Patients who did not attend had significantly lower scores in VHI, VHI-10, and each of the VHI domains. There was a significant difference in age between VT groups, with those electing to not attend representing older age. Patients who attended VT were more likely to use their voice for work (P = .015). There were statistically significant differences among the groups for six VHI question items. CONCLUSIONS: Understanding patient motivations, whether a patient uses their voice for work, and specific responses to the VHI questionnaire may allow clinicians to better understand patient engagement in voice therapy.

Practice Patterns of Referring Physicians in Management of the Dysphonic Patient.

Objective Dysphonia is commonly encountered by primary care physicians and general otolaryngologists. We examine practice patterns of referring physicians to a tertiary voice clinic, including adherence to evidence-based guidelines. Study Design Retrospective case series with chart review. Setting Academic tertiary care hospital. Subjects and Methods In total, 821 charts of patients with voice complaints seen at a tertiary voice clinic between January 2011 and June 2016 were reviewed. Included charts (n = 755) were reviewed for type of referring provider, prior diagnoses, and treatments employed by referring physicians. Additional information regarding findings at the time of laryngoscopy/stroboscopy and diagnoses provided by a laryngologist were also obtained. Statistical analysis was performed to determine significant relationships between variables of interest. Results A total of 244 patients (32.2%) received a diagnosis prior to evaluation in the voice clinic, most commonly laryngopharyngeal reflux disease (n = 134). Prior medical treatment was attempted in 221 (29.3%) patients, typically antireflux medications (n = 141). Of the patients treated with proton pump inhibitors by referring physicians, 65.1% lacked symptoms of gastroesophageal reflux disease. Patients with prior treatment had a median duration of symptoms 6 weeks longer than those without prior treatment ( P = .04). Among previously diagnosed patients, 199 (81.6%) of diagnoses changed after evaluation in the voice clinic. Conclusion Referring physicians frequently treat dysphonic patients empirically, often with antireflux medications. Subspecialist evaluation results in changes in diagnosis in many patients. Empiric treatment can delay referral and appropriate treatment.

Analyzing the Area Under the Curve of Pharyngeal pH Probes in the Diagnosis of Reflux Disease.

OBJECTIVES: To analyze the area under the curve (AUC) from 24-hour pharyngeal pH probes and evaluate this parameter as a predictor of disease severity for laryngopharyngeal reflux. METHODS: Eighty patients met inclusion criteria of a completed 24-hour pharyngeal pH probe and Reflux Symptom Index (RSI) questionnaire. The AUC was calculated below a pH threshold of 5.5 using the trapezoidal rule. The RSI and RYAN scores were correlated with AUC values, and nonparametric tests were used for comparisons. RESULTS: The median AUC value was 18 007 pH-seconds with an interquartile range (IQR) of 63 156, the median RSI score was 21 (IQR = 16), and the median RYAN score was 15.3 (IQR = 78). There was a Spearman's correlation of .36 between the RSI scores and AUC values ( P = .001) and a moderate correlation between AUC values and RYAN scores (0.58, P < .001). An insignificant correlation of .19 between RYAN scores and RSI scores was observed ( P = .09). CONCLUSIONS: The AUC may be a useful objective value in establishing the diagnosis of laryngopharyngeal reflux. Prospective studies with larger patient populations are necessary to validate these findings and determine standardized thresholds for symptomatic patients.

Perceptual evaluation of voice quality and its correlation with acoustic measurements.

To determine whether a correlation exists between the Grade, Roughness, Breathiness, Aesthenia, Strain (GRBAS) scale (a subjective measure of voice) and the Multi-Dimensional Voice Program (MDVP) scale (an objective measure of voice). A retrospective review of 37 voice patients (12 male/25 female) was conducted. Each voice was perceptually evaluated using the GRBAS scale by an experienced speech pathologist and acoustically analyzed using the MDVP scale. Statistical analysis using a multivariate regression model identified a significant correlation between the noise-related parameters of MDVP and the components of the GRBAS scale. Grade correlated with voice turbulence index (VTI), noise harmonic ratio (NHR), and soft phonation index (SPI). Roughness correlated with NHR only. Breathiness correlated with SPI only. Aesthenia also correlated with SPI only. Of the 19 acoustic variables measured by the MDVP system, only three noise parameters significantly correlated with the GRBAS perceptual voice analysis. Perhaps "noise" is the perceived acoustical quality of the dysphonic voice. A voice quantifying measure such as a "voice index score" could be proposed using the GRBAS scoring and the three clinically relevant MDVP values following further studies.
