Objectives To identify the differences in sensitivity and accuracy between ultrasound‐guided and palpation‐guided fine needle aspirations (FNA) of suspicious lymph nodes in patients with human papillomavirus (HPV) (+) oropharyngeal squamous cell carcinoma (OPSCC). Additional objectives included identifying patient specific factors affecting biopsy accuracy and evaluating potential differences in accuracy between fine and core needle biopsies. Study Design Retrospective chart review. Materials and Methods A retrospective study of diagnostic sensitivity was completed at a single tertiary care center between 1/1/2006–12/31/2016. Participants included patients who underwent pretreatment FNA biopsy with HPV(+)OPSCC confirmed pathologically following neck dissection or excisional lymph node biopsy. A true positive (TP) on FNA biopsy was defined as an FNA biopsy concerning for squamous cell carcinoma (SCC) that was confirmed on excisional biopsy or neck dissection. A false negative (FN) was defined as a negative FNA but metastatic disease identified on excisional biopsy or neck dissection. Sensitivity was calculated as TPs/(TPs + FNs). Sensitivity was compared among techniques using chi‐square and Fisher exact tests. Results A total of 209 FNA biopsies among 198 patients were included in the study, including 31 (15%) palpation‐guided FNAs, 160 (77%) ultrasound‐guided FNAs, and 18 (9%) ultrasound‐guided FNA + core biopsies. Sensitivity was significantly different among palpation‐guided FNA, ultrasound‐guided FNA, and ultrasound‐guided FNA + core biopsies (48% vs. 83% vs. 94%, respectively; P < .001) but there was no significant difference in sensitivity between ultrasound‐guided FNA versus ultrasound‐guided FNA + core biopsies ( P = .31). Conclusion The use of ultrasound guidance in FNA biopsies of nodal metastases in HPV(+)OPSCC improves sensitivity compared to palpation guidance alone. Ultrasound guided biopsies are preferred in patients with suspected nodal metastasis from HPV(+)OPSCC. Level of Evidence 3 Laryngoscope , 132:2396–2402, 2022

AbstractObjectivesTo examine the degree of agreement between MRI and histologically generated volumetric measurements of residual injection laryngoplasty material.MethodsFollowing left recurrent laryngeal nerve transection, rabbit vocal cords were injected with jellyfish collagen, Cymetra®, or Restylane®. Laryngeal tissue was harvested 4 or 12 weeks post injection followed by MRI imaging and histologic cross‐sectioning. Two raters estimated the volume of remaining injection material in specimens within MRI and histologic axial cross sections. Wilcoxon signed rank tests were employed to detect gross differences between inter‐rater measurements and between imaging modalities across time. Agreement between rater measurements and imaging (histology and MRI) was assessed using intra‐class correlation coefficients.ResultsData was available from 16 rabbits sacrificed at 4 weeks (n = 8) and 12 weeks (n = 8). Inter‐rater testing of MRI imaging revealed no significant differences (p > .05) between rater measurements across time points, and excellent agreement (0.93; 95% confidence interval 0.80–0.98) while histologically estimated volumes demonstrated a significant difference at 4 weeks (p < .05) and overall good agreement (0.89; 95% confidence interval 0.59–0.97). Comparison of MRI and histologically estimated volume measurements revealed significant differences at the 4‐week time point (p < .05) but not at 12 weeks (p > .05). Overall, there is only moderate agreement between MRI and histology estimates (0.72; 95% confidence interval 0.22–0.90).ConclusionsMRI imaging demonstrates good reliability and similar estimates of volume to histologically estimated measurements of residual injection laryngoplasty material at time points clinically relevant for future injection laryngoplasty experiments.Level of EvidenceNA.

Objective: To characterize current awareness, perceptions, and literacy surrounding hearing loss among the adult population in the United States. Study Design: National cross-sectional survey study. Setting: United States. Patients: Adults between 50 and 80 years of age in the United States. Results: Survey respondents included 1,250 adults between the ages of 50 and 80 years, including 500 who indicated at least moderate hearing loss and were using hearing aids and 750 who denied having hearing loss and were not using hearing aids. Only 9% of patients were able to correctly identify what constitutes a “normal” or “average” range for hearing. By comparison, a “normal” range of values for vision, blood pressure, and total cholesterol were identified correctly by 93%, 85%, and 52% of the 1,250 surveyed adults, respectively. When asked to rank the importance of addressing hearing loss within the context of 10 other common health conditions, hearing loss was ranked third to least important. When considering annual health maintenance, respondents indicated they were “very likely” to have an annual physical exam (72%), a cholesterol test (70%), an eye exam (66%), and bring their pet to a veterinarian (59%) over twice as frequently as having their hearing evaluated (27%). When evaluating awareness surrounding associations between hearing loss and other health and social issues, less than one-fourth indicated strong awareness about links between hearing loss and depression, employability and income, fall risk, dementia, and type 2 diabetes. While most patients acknowledge the potential impacts of hearing loss on safety, quality of life, and health, less than half believe that hearing loss is treatable and less than 20% believe that hearing loss is preventable. Conclusion: Despite widespread literacy of what constitutes normal vision, blood pressure, and total cholesterol levels, respondents exhibit substantially poorer understanding of “normal” hearing levels. Most adults believe that few treatment options exist for the management of hearing loss. Underlying the uniformly limited literacy surrounding hearing loss and its treatment options is the adult population's lack of appreciation for the long-term health sequelae of untreated hearing loss.

ObjectiveInvestigate oncologic and functional outcomes associated with transhyoid and lateral pharyngotomy (transpharyngeal) approaches in the treatment of oropharyngeal squamous cell carcinoma (OPSCC).Study DesignRetrospective review.SettingSingle institution (tertiary care center).MethodsThis is a retrospective case series of patients with OPSCC undergoing transpharyngeal resection from 1990 to 2017 at Mayo Clinic. Oncologic outcomes, postoperative complications, objective swallowing data, and rates of tracheostomy and percutaneous gastrostomy tube dependence were recorded.ResultsOf 83 patients meeting inclusion criteria, 56 (68%) were human papillomavirus positive. Overall survival rates at 5 and 10 years following surgery were 85% and 80%, respectively. Cancer‐specific survival rates at these same time points were 90% and 88%. Following treatment, 35 of 49 patients (71%) had a Functional Oral Intake Scale score ≥5, indicating total oral intake of multiple consistencies; 79 of 82 (96%) were without tracheostomy or laryngectomy; and 71 of 81 (88%) were on a full oral diet.ConclusionTranspharyngeal approaches provide adequate functional and oncologic outcomes in the majority of patients with OPSCC. These results may have important implications for patients who are not candidates for, or are unwilling to undergo, nonoperative therapy or for those without access to radiation therapy.

Abstract Background The current study aims to characterize the natural history of sporadic vestibular schwannoma volumetric tumor growth, including long-term growth patterns following initial detection of growth. Methods Volumetric tumor measurements from 3505 serial MRI studies were analyzed from unselected consecutive patients undergoing wait-and-scan management at three tertiary referral centers between 1998 and 2018. Volumetric tumor growth was defined as a change in volume ≥20%. Results Among 952 patients undergoing observation, 622 experienced tumor growth with initial growth-free survival rates (95% CI) at 1, 3, and 5 years following diagnosis of 66% (63–69), 30% (27–34), and 20% (17–24). Among 405 patients who continued to be observed despite demonstrating initial growth, 210 experienced subsequent tumor growth with subsequent growth-free survival rates at 1, 3, and 5 years following initial growth of 77% (72–81), 37% (31–43), and 24% (18–31). Larger tumor volume at initial growth (HR 1.13, P = .02) and increasing tumor growth rate (HR 1.31; P &lt; .001) were significantly associated with an increased likelihood of subsequent growth, whereas a longer duration of time between diagnosis and detection of initial growth was protective (HR 0.69; P &lt; .001). Conclusions While most vestibular schwannomas exhibit an overall propensity for volumetric growth following diagnosis, prior tumor growth does not perfectly predict future growth. Tumors can subsequently grow faster, slower, or demonstrate quiescence and stability. Larger tumor size and increasing tumor growth rate portend a higher likelihood of continued growth. These findings can inform timing of intervention: whether upfront at initial diagnosis, after detection of initial growth, or only after continued growth is observed.

Objectives: Compare speech perception performance growth and benchmark score achievement among adult cochlear implant (CI) recipients with single-sided deafness (SSD) versus bilateral moderate to profound hearing loss. Study Design: Retrospective matched cohort analysis. Setting: Tertiary referral center. Patients: Adults with SSD or bilateral moderate to profound hearing sensorineural hearing loss who underwent cochlear implantation from 2014 to 2019. Interventions: Cochlear implantation. Main outcome measures: Time-to-benchmark speech perception score (CNC, AzBio in quiet) and speech performance within first postoperative year. Results: Thirty-three SSD patients were matched to 66 bilateral hearing loss patients (referent cohort) for duration of deafness and preoperative ipsilateral CNC scores. Although SSD patients were more likely to achieve benchmark CNC scores more quickly compared with matched referents, this difference did not reach statistical significance (HR 1.72; 95% CI 0.78–3.82; p = 0.18). AzBio scores showed similar trends (HR 1.40; 95% CI 0.66–2.98; p = 0.38). At last follow-up, the SSD cohort had lower CNC (median 54% vs. 62%; p = 0.019) and AzBio scores (median 72% vs. 84%; p = 0.029) compared to the referent cohort. Conclusions: No significant difference in speech perception performance growth (i.e., time-to-benchmark speech perception score) was identified between SSD and bilateral hearing loss CI recipients, although patients with bilateral hearing loss achieved higher scores in the implanted ear within the first year of follow-up.

Objectives/Hypothesis To review hearing preservation after microsurgical resection of sporadic vestibular schwannomas according to tumor size. Study Design Retrospective cohort. Methods Baseline, intraoperative, and postoperative patient and tumor characteristics were retrospectively collected for a cohort who underwent hearing preservation microsurgery. Serviceable hearing was defined by a pure tone average ≤50 dB and word recognition score ≥50%. Results A total of 243 patients had serviceable hearing preoperatively. Fifty (21%) tumors were confined to the internal auditory canal, and the median tumor size was 16.2 mm (interquartile range [IQR] 11.3–23.2) for tumors with cerebellopontine angle extension. Serviceable hearing was maintained in 64% of patients with tumors confined to the internal auditory canal, 28% with cerebellopontine angle extension <15 mm, and 9% with cerebellopontine angle extension ≥15 mm. On multivariable analysis, the odds ratios of acquiring nonserviceable hearing postoperatively for tumors extending <15 mm and ≥15 mm into the cerebellopontine angle were 5.75 (95% confidence interval [CI] 2.13–15.53; P < .001) and 22.11 (95% CI 7.04–69.42; P < .001), respectively, compared with intracanalicular tumors. Conclusions The strongest predictor of hearing preservation with microsurgery after multivariable adjustment is tumor size. Approximately 10% of patients with tumors ≥15 mm of cerebellopontine angle extension will retain serviceable hearing after microsurgery. Furthermore, hearing preservation techniques offer cochlear nerve preservation and cochlear patency allowing for possible future cochlear implantation. An attempt at hearing preservation, including avoiding surgical approaches that necessarily sacrifice hearing, is worthwhile even in larger tumors if serviceable hearing is present preoperatively.
