Clinical Voice Outcomes for Two Voice Rest Protocols after Phonomicrosurgery.

OBJECTIVES: Voice rest is commonly recommended for patients with benign vocal fold lesions (BVFLs) after phonomicrosurgery. The study compares the clinical voice outcomes of two protocols, 7-day complete voice rest (CVR) and 3-day CVR followed by 4-day relative voice rest (CVR + RVR), for patients with BVFLs after phonomicrosurgery. STUDY DESIGN: Prospective, randomized controlled trial. METHOD: Patients with BVFLs undergoing phonomicrosurgery were recruited prospectively and randomly assigned to either protocol. Outcomes were assessed on objective measures of acoustics (fundamental frequency, frequency range, mean intensity, cepstral peak analysis) and aerodynamics (vital capacity, airflow rate, subglottal pressure, phonation threshold pressure), as well as subjective measures, both provider-reported through the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V), and patient-reported through the Voice Handicap Index (VHI). Clinical measures were collected at three-time points: preoperatively, 1-week postoperatively (on voice rest), and 1-month postoperatively. In addition, adherence was estimated using a vocal dosimeter. RESULTS: Twenty-five patients were recruited and randomized to 7-day CVR (n = 13) and CVR + RVR regimen (n = 12). Statistically significant changes were found within both groups for subglottal pressure (p = 0.03) and VHI score (p < 0.001) comparing pre-operative baseline to 1-month postoperative follow-up. There were no statistically significant differences between the groups. Regardless of group assignment, a significant decrease in overall severity ratings for the CAPE-V was found by comparing the preoperative scores to postoperative scores at 1-week (p < 0.001) and 1-month (p < 0.001). CONCLUSION: Both groups improved their overall voice quality comparably 1 month after undergoing phonomicrosurgery as measured by objective and subjective parameters. LEVELS OF EVIDENCE: 2.

Optimization of Opioid Discharge Prescriptions Following Thyroid and Parathyroid Surgery.

OBJECTIVE: To evaluate the impact of a quality improvement bundle on opioid discharge prescribing following thyroidectomy and parathyroidectomy. METHODS: This before-and-after study included patients undergoing thyroidectomy or parathyroidectomy at an academic medical center. The quality improvement bundle included a patient education flyer, electronic health record order sets with multimodal analgesia regimens, and provider education. The preimplementation cohort included patients treated from January 2018 to December 2019. The postimplementation cohort included patients treated from June 2021 to August 2021. The primary outcome was the proportion of patients who received new opioid discharge prescriptions. RESULTS: A total of 160 patients were included in the preimplementation cohort, and the first 80 patients treated after bundle implementation were included in the postimplementation cohort. Patients receiving new opioid discharge prescriptions decreased from 80% (128/160) in the preimplementation cohort to 35% (28/80) in the postimplementation cohort with an unadjusted absolute reduction of 45% (95% CI, 33%-57%; P < .001; number needed to treat = 3) and an adjusted odds ratio (OR) of 0.08 (95% CI, 0.04-0.19; P < .001). The bundle was associated with reductions in opioid discharge prescriptions that exceeded 112.5 oral morphine milligram equivalents (33% pre- vs 10% postimplementation; adjusted OR, 0.20; P = .001) or 5 days of therapy (17% pre- vs 6% postimplementation; adjusted OR, 0.34; P = .049). DISCUSSION: Implementation of a pain management quality improvement bundle reduced opioid discharge prescribing following thyroidectomy and parathyroidectomy. IMPLICATIONS FOR PRACTICE: Unnecessary opioid prescriptions generate unused opioids in patients' homes that can lead to opioid misuse. We believe that this bundle reduced the risk for opioid misuse in our community. REGISTRATION: The study was registered at ClinicalTrials.gov (NCT04955444) before implementation.

Outcomes of carotid-sparing IMRT for T1 glottic cancer: Comparison with conventional radiation.

OBJECTIVES: We aim to report oncologic outcomes after conventional radiotherapy (ConRT) using opposed lateral beams and intensity-modulated radiation therapy (IMRT) for tumor (T)1 nodal (N)0 T1 N0 glottic squamous cell carcinoma. STUDY DESIGN: Retrospective case-control study. METHODS: We retrospectively reviewed demographic, disease, and treatment characteristics for patients treated at our institution during 2000 to 2013. RESULTS: One hundred fifty-three patients (71%) were treated using ConRT and 62 (29%) using IMRT. The median follow-up for all patients was 68 months. There was no statistically significant difference in 5-year local control between patients with T1a versus T1b disease (94% vs. 89%, respectively, P = 0.5). Three-year locoregional control for patients treated with ConRT was 94% compared to 97% with IMRT (P = 0.4). Three-year overall survival (OS) for patients treated with ConRT was 92.5% compared with 100% with IMRT (P = 0.1). Twelve of 14 patients with local recurrence underwent salvage surgery with 5-year ultimate locoregional control of 98.5% and 97.1% in the ConRT and IMRT cohorts, respectively (P = 0.7). Multivariate analysis showed age < 60 years (P < 0.0001) and pretreatment Eastern Cooperative Oncology Group performance status <2 (P = 0.0022) to be independent correlates of improved OS. Postradiation cerebrovascular events were in four patients in the ConRT cohort (3%), whereas no patients in the IMRT cohort suffered any events. CONCLUSION: Because the oncologic outcomes for patients treated with IMRT were excellent and IMRT allows for carotid sparing, we have transitioned to IMRT as our standard for most patients with T1 glottic cancer.

Pediatric recurrent laryngeal nerve reinnervation: A case series and analysis of post-operative outcomes.

OBJECTIVE: To provide detailed information about recurrent laryngeal nerve (RLN) reinnervation outcomes in children using objective measures. METHODS: The records of three pediatric patients with unilateral vocal cord paralysis that underwent RLN reinnervation were retrospectively reviewed. Fundamental frequency (F0), jitter, shimmer, noise-to-harmonic ratio (NHR), and voice phonation (sustained /s/, /z/, /a/) were measured preoperatively and post-operatively at 13, 9, and 33 months (each time period corresponding to one of the three patients). RESULTS: Mean preoperative and post-operative variables were as follows: shimmer, 9.65±1.02% vs. 4.46±0.71% (p=0.01); NHR, 0.296±0.063 vs. 0.127±0.011 (p=0.04); jitter, 3.57±0.89% vs. 1.46±0.54% (p=0.08); F0, 274.6±35.4Hz vs. 282.2±70.6Hz (p=0.44); maximum phonation time, 7.46±1.40s vs. 9.79±1.84s (p=0.22); /s:z/ ratio, 1.28±0.22 vs.1.07±0.09 (p=0.26). CONCLUSIONS: There was statistically significant improvement in shimmer and NHR. Jitter improvement approached statistical significance. All other variables failed to show significant improvement among this small sample size. RLN reinnervation for pediatric patients is an option for the treatment of vocal cord paralysis. Further studies with larger cohorts are needed to show the full benefits.

Diagnostic assessment of laryngeal cancer.

Laryngeal carcinoma must be diagnosed expeditiously to maximize curative efforts. Our approach combines useful aspects of the patient's presentation with application of appropriate diagnostic modalities. Newer methods of assessment and follow-up are being scientifically validated and will likely enhance the diagnostic efforts of the head and neck surgical oncologist.

Vocal fold augmentation with injectable calcium hydroxylapatite: short-term results.

Symptoms of unilateral vocal fold paralysis are improved significantly by augmenting the paralyzed vocal fold via vocal fold injection. In this trial, augmentation with a new calcium hydroxylapatite implant was evaluated. In addition, two different phonosurgical injection techniques were used, and these procedures were compared for accuracy and reliability. A total of 11 terminal patients with unilateral vocal fold paralysis underwent vocal fold injection with calcium hydroxylapatite. Efficacy of the implant was evaluated by comparing results from the Voice Handicap Index (VHI) and mean airflow measurements before and 6 months after injection. Surgeon evaluations determined the comparative benefits of either endoscopic direct vocal fold injection or percutaneous vocal fold injection. Six-month data were obtained for a cohort of five patients. VHI scores improved for all five patients available for full evaluation and four of the five achieved improvements in mean airflow rates. Of the remaining patients, one later had a medialization laryngoplasty, two died from their terminal diseases before the 6-month follow-up, and two of the remaining three reported satisfaction with the results via telephone follow-up. Vocal fold injection via endoscopic, direct laryngoscopy was found to be a more reliable procedure for vocal fold injection than percutaneous injection. Slight overinjection (10% to 15%) was found to provide optimum results. Vocal fold injection of calcium hydroxylapatite for unilateral vocal fold paralysis improved voice quality and reduced mean airflow rates in this patient group with short-term results. Long-term studies are needed to confirm the durability of these findings.

Ehlers-Danlos syndrome presenting as dysphonia and manifesting as tongue hypermobility: Report of 2 cases.

Ehlers-Danlos syndrome (EDS) comprises a group of related hereditary connective tissue diseases. EDS manifests as joint hypermobility, tissue elasticity, and easy bruising. Although affected patients typically present to primary care physicians, orthopedists, and rheumatologists, some head and neck symptoms (e.g., dysphonia, dysphagia, and/or temporomandibular joint complaints) may direct some to an otolaryngologist. We describe the cases of 2 patients who presented to our otolaryngology clinic for evaluation of dysphonia. On physical examination, both exhibited tongue hypermobility, and both were subsequently diagnosed with EDS. We also review the results of our comprehensive literature search, in which we found only 3 articles that specifically described tongue hypermobility; in each case, the hypermobility was related to EDS. Finally, we discuss presentations of EDS that otolaryngologists might encounter.
