Oral cancer incidence rate is associated with access to dental care: City and statewide analyses.

INTRODUCTION: Access to dental care may affect diagnosis of oral squamous cell carcinoma (OSCC). We tested whether the incidence rate of OSCC is higher in regions with less dental care access in the city of Chicago and state of Illinois. STUDY DESIGN: Ecological cohort. SETTING: Population, outpatients, and inpatients. METHODS: We extracted 5-year averages of the state-wide county-level and city-level OSCC incidence rates from 2015 to 2019 from the Illinois Department of Public Health. Dental care access information was also collected for each county for the same period, as well as the percentage of people that had ≥1 visit to a dentist in the previous year in Chicago. Multivariate Poisson regression was used to investigate the relationship between county-level access to dental care (and city-level dentist visits) and OSCC incidence rate, controlling for confounders, with additional flexible semiparametric models for confirmatory sensitivity analysis. RESULTS: In Illinois, higher 5-year incidence rate of OSCC was significantly associated with low access to dental care by county (IRR = 0.96, 95% CI 0.91, 0.98). Southern/southwestern counties had higher incidence rates of OSCC (15.5%-28.4%) and the lowest rates of dental care access (47.5%-69.2%) compared to northern counties (10.3%-15% and 55.4%-80.6%, respectively). In Chicago, people with more dentist visits had a reduced chance of being diagnosed with OSCC (IRR = 0.97, 95% CI 0.91, 0.99), consistent with state-wide analyses. CONCLUSION: OSCC incidence rate is closely associated with poor local dental healthcare access in a major state and urban city. Increasing dental access could improve cancer outcomes via improved oral health and earlier detection.

Air pollution is associated with increased incidence-rate of head and neck cancers: A nationally representative ecological study.

INTRODUCTION: Early studies show conflicting findings regarding particulate matter ≤ 2.5 µm in diameter (PM2.5) exposure and development of head and neck cancers (HNC). We analyzed the relationship between PM2.5 exposure and various types of HNC in a nationally representative ecological sample. METHODS: We determined HNC incidence in 608 US counties from 2011 to 2019 using the Surveillance, Epidemiology and End Results (SEER) Program from the National Cancer Institute. We also collected information on sociodemographic factors from SEER and data on smoking and alcohol intake from CDC data frames (county level). PM2.5 exposure levels were estimated using satellite and meteorological data via previously validated general additive models. Flexible semi-nonparametric regression models were used to test the relationship between PM2.5 exposure levels and HNC incidence, adjusting for demographics, socioeconomic factors, and comorbidity. RESULTS: Increased PM2.5 exposure levels were associated with higher incidence-rates of oral cavity and pharyngeal cancers controlling for confounders in our primary analyses (IRR = 1.04, 95 % CI 1.01, 1.07, p = 0.02 per 1 µg/m3 increase in PM2.5). This relationship was maintained after adjusting for multiple testing (Holm s method, p = 0.04) and in ordinary least squares (OLS) regression (ß = 0.17, 95 % CI 0.01, 0.57, p = 0.01). Increased exposure was also associated with other HNC: esophagus (IRR = 1.06, 95 % CI 1.01, 1.11, p = 0.02), lip (IRR = 1.16, 95 % CI 1.03, 1.31, p = 0.01), tonsil (IRR = 1.10, 95 % CI 1.03, 1.16, p < 0.01). However, these relationships were not maintained in secondary analyses. CONCLUSIONS: This nationally representative ecological study shows that increased levels of air pollution are associated with increased incidence of overall oral cavity and pharyngeal cancers in the US.

Racial Disparities in Head and Neck Cancer: It's Not Just About Access.

OBJECTIVE: Medical literature identifies stark racial disparities in head and neck cancer (HNC) in the United States, primarily between non-Hispanic white (NHW) and non-Hispanic black (NHB) populations. The etiology of this disparity is often attributed to inequitable access to health care and socioeconomic status (SES). However, other contributors have been reported. We performed a systematic review to better understand the multifactorial landscape driving racial disparities in HNC. DATA SOURCES: A systematic review was conducted in Covidence following Preferred Reporting Items for Systematic Reviews and Meta-analyses Guidelines. A search of PubMed, SCOPUS, and CINAHL for literature published through November 2022 evaluating racial disparities in HNC identified 2309 publications. REVIEW METHODS: Full texts were screened by 2 authors independently, and inconsistencies were resolved by consensus. Three hundred forty publications were ultimately selected and categorized into themes including disparities in access/SES, treatment, lifestyle, and biology. Racial groups examined included NHB and NHW patients but also included Hispanic, Native American, and Asian/Pacific Islander patients to a lesser extent. RESULTS: Of the 340 articles, 192 focused on themes of access/SES, including access to high-quality hospitals, insurance coverage, and transportation contributing to disparate HNC outcomes. Additional themes discussed in 148 articles included incongruities in surgical recommendations, tobacco/alcohol use, human papillomavirus-associated malignancies, and race-informed silencing of tumor suppressor genes. CONCLUSION: Differential access to care plays a significant role in racial disparities in HNC, disproportionately affecting NHB populations. However, there are other significant themes driving racial disparities. Future studies should focus on providing equitable access to care while also addressing these additional sources of disparities in HNC.

A Nationwide Analysis of Head and Neck Fibromatoses.

BACKGROUND: Head and neck fibromatoses (HNFs) are a rare, diverse group of soft tissue tumors characterized by an abnormal proliferation of fibroblasts. Available literature on these tumors is limited to case reports and small single-institutional studies. OBJECTIVE: We aim to provide demographic, socioeconomic, tumor-related, and treatment characteristics of HNFs. DESIGN: Retrospective cohort analysis using the National Cancer Database (NCDB). METHODS: The NCDB was queried for fibromatosis-related histologic codes located within the head and neck region. Various factors were analyzed. Univariate and multivariate survival analyses were performed. RESULTS: Between 2004 and 2016, 130 patients were included in the analyses. Average age was 57.4 years old with a predominance of White (83.6%) males (61.5%). Non-desmoid HNFs accounted for 60%-70% of the tumors. The salivary gland was the most common location (38.5%) and more than half of the tumors were high grade. The majority were treated surgically (90.8%) and 25% had positive margins. Mean and median overall survival (OS) were 98.9 and 135.4 months, respectively. Surgery is associated with better OS than nonsurgical alternatives. Addition of adjuvant treatments was not associated with differences in survival. CONCLUSION: In the largest study to date, we describe demographic, socioeconomic, tumor-related, and treatment patterns of patients with this rare disease. These tumors are most frequently present in middle-aged males with high-grade histology. Most are treated surgically and positive surgical margins are common. Surgery has better OS than nonsurgical alternatives. While adjuvant radiation has become more common, we found no difference in survival compared to surgery alone. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:2228-2235, 2024.

A nationwide analysis of salvage surgery for laryngeal cancer in the elderly.

BACKGROUND: We aim to describe outcomes of elderly patients undergoing salvage surgery for laryngeal cancer and to characterize the interplay of age with various other factors in this growing population. METHODS: Using the National Cancer Database, we identified cases of salvage laryngectomy in patients who failed chemoradiation. An age cutoff of 70 years was used to separate subjects into two groups. Various factors were compared. RESULTS: Of the 825 patients included, 166 (20.1%) were elderly. Elderly patients had worse overall survival (p = 0.001), higher 30-day and 90-day mortality (p = 0.006, p < 0.001), and a longer length of stay (LOS) (p = 0.015). LOS over 1 week was associated with worse survival (p = 0.032). CONCLUSION: Elderly patients had worse overall perioperative survival than their younger counterparts. LOS and 30-day readmissions were associated with higher risk of mortality in this group. We provide a contemporary set of relevant information for head and neck cancer providers to consider in this growing population.

Laryngeal Chondrosarcoma Characteristics and Survival Analysis in the National Cancer Database.

OBJECTIVE: To highlight various patient, tumor, diagnostic, and treatment characteristics of laryngeal chondrosarcoma (LC) as well as elucidate factors that may independently affect overall survival (OS) for LCs. STUDY DESIGN: Retrospective cohort study. SETTING: National Cancer Database (NCDB). METHODS: All LC cases from 2004 to 2016 were extracted from the NCDB. Several demographic, diagnostic, and treatment variables were compared between LC subgroups using χ2 and analysis of variance tests. Univariate and multivariate survival analyses were performed for LCs using univariate Kaplan-Meier analysis and Cox proportional hazards regression models. RESULTS: There were 348 LCs included in the main cohort. LCs were predominantly non-Hispanic white males with similar rates of private and government insurance (49.4% vs 45.4%). Most LCs (81.6%) underwent primary surgery, particularly partial and total laryngectomy. The 1-, 5-, and 10-year survivals for LC were 95.7%, 88.2%, and 66.3%, respectively. On multivariate analysis, lack of insurance (P = .019; hazard ratio [HR], 8.21; 95% CI, 1.40-48.03), high grade (P = .001; HR, 13.51; 95% CI, 3.08-59.26), and myxoid/dedifferentiated histological subtypes (P = .0111; HR, 10.74; 95% CI, 1.71-67.33) correlated with worse OS. No difference in OS was found between partial and total laryngectomy. CONCLUSION: This is the first multivariate survival analysis and largest single cohort study of LCs in the literature. Overall, LCs enjoy an excellent prognosis, with insurance status, grade, and histology as the main predictors of survival.

Costs Associated With Imaging Surveillance After Treatment for Head and Neck Cancer.

Importance: The National Comprehensive Cancer Network recommends imaging within 6 months after treatment for head and neck cancer (HNC). Further imaging is recommended only if the patient has symptoms or abnormal findings on physical examination. However, in many instances, asymptomatic patients continue to have imaging evaluations. Objectives: To assess practice patterns in surveillance imaging in patients with HNC and evaluate the costs associated with these imaging practices. Design, Setting, and Participants: This single-institution retrospective economic evaluation study screened 435 patients to identify patients newly diagnosed with head and neck mucosal and salivary gland malignant tumors between January 1, 2010, and December 31, 2016. Data analyses were performed from October 25, 2018, to November 24, 2020. Exposure: Imaging practice patterns. Main Outcomes and Measures: Number and costs of imaging studies during the surveillance period for all patients, patients who remained disease free, and patients who developed recurrence. Results: A total of 136 patients (mean [SD] age at diagnosis, 62 [14] years; 84 [61.8%] male; 106 [77.9%] White) with HNC were included in the study. The oropharynx was the most common subsite (64 [47.1%]), most HNCs were stage IVA (62 [45.6%]), and most patients received definitive radiation-based treatment (71 [52.2%]). During the median surveillance period of 3.2 years (range, 0.3-6.8 years), a mean (SD) of 14 (10) imaging studies were performed for all patients, with a mean (SD) total cost of $36 800 ($24 500). In patients who remained disease free, a mean (SD) of 13 (10) imaging studies were performed during the surveillance period, with a mean (SD) total cost of $35 000 ($21 700). Patients who lacked symptoms had a mean (SD) of 4 (3) studies performed per year, resulting in a mean cost of $9600 ($5900) per year. Patients who developed recurrence had more studies per year of follow-up (mean difference, 5.0; 95% CI, 3.4-6.6) and higher associated mean costs (mean difference, $10 600; 95% CI, $6100-$15 000) than patients who remained disease free. Conclusions and Relevance: In this economic evaluation study, many patients treated for HNCs received imaging studies beyond what is recommended by National Comprehensive Cancer Network guidelines. These findings suggest that the cost burden of imaging in the asymptomatic patient needs to be considered against the value obtained from routine imaging in this current health care environment.

Prognostic value of lymph node ratio versus American Joint Committee on Cancer N classification for surgically resected human papillomavirus-associated oropharyngeal squamous cell carcinoma.

BACKGROUND: We compared prognostic values of lymph node ratio (LNR) and AJCC 8 N classification in surgically resected human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC). METHODS: Using the National Cancer Database, we identified patients with HPV-associated OPSCC from 2010 to 2016 who underwent definitive surgical resection. Patients were analyzed by nodal grouping (LNR, N stage) and adjuvant radiation therapy(RT). Primary endpoint was overall survival. RESULTS: We identified 4166 patients. Survival analysis showed significant improvement for LNR≤6% versus >6% (5 year OS% 92.7% vs. 83.7%, p < 0.001). N classification demonstrated good prognostic ability (5 year OS% for pN0, pN1, pN2 were 91.3%, 90.1%, 78.8%, p < 0.001), but poor separation among stages (compared to pN0: pN1 HR 1.40 [95% CI 0.63, 3.09], p = 0.41; pN2 HR 2.50 [95% CI 1.08, 5.81], p = 0.033). RT improved survival in the LNR > 6% group (5 year OS% 85.4% vs. 74.9%, p < 0.001; HR 0.41 [95% CI 0.28, 0.58], p < 0.001). CONCLUSIONS: LNR should be considered an adjunct category in future staging systems for HPV-associated OPSCC.

Effect of HPV Status on Survival of Oropharynx Cancer with Distant Metastasis.

Human papillomavirus (HPV)-positive oropharynx squamous cell carcinoma (OPSCC) is known to have improved survival over HPV-negative disease. However, it is largely unknown whether HPV status similarly affects survival in patients presenting with distant metastatic disease. We queried the National Cancer Database for OPSCC with distant metastasis. Kaplan-Meier curves and Cox proportional hazards regression models controlling for relevant demographics were used to evaluate overall survival. In total, 768 OPSCC cases were available for analysis with HPV and survival data: 50% of cases were HPV negative and 50% were HPV positive. The 1- and 2-year survival for HPV-negative disease was 49% and 27%, respectively, as compared with 67% and 42% in the HPV-positive cohort. HPV positivity was associated with improved median survival in treated and untreated patients. Age, comorbidities, and HPV status were predictive of improved survival on multivariate analysis. HPV-positive OPSCC has improved survival in the setting of distant metastatic presentation as compared with HPV-negative disease and shows greater responsiveness to treatment.

A contemporary analysis of racial disparities in recommended and received treatment for head and neck cancer.

BACKGROUND: Racial disparities in squamous cell carcinoma of the head and neck (HNSCC) negatively affect non-Hispanic black (NHB) patients. This study was aimed at understanding how treatment is prescribed and received across all HNSCC subsites. METHODS: With the National Cancer Database, patients from 2004 to 2014 with surgically resectable HNSCCs, including tumors of the oral cavity (OC), oropharynx (OP), hypopharynx (HP), and larynx (LX), were studied. The treatment received was either upfront surgery or nonsurgical treatment. Treatment patterns were compared according to race and subsite, and how these differences changed over time was evaluated. RESULTS: NHB patients were less likely than non-Hispanic white (NHW) patients to receive surgery across all subsites (relative risk [RR] for OC, 0.87; RR for OP, 0.75; RR for HP, 0.73; RR for LX, 0.87; all P values <.05). They were also more likely to refuse a recommended surgery (RR for OC, 1.50; RR for OP, 1.23; RR for HP, 1.23; RR for LX, 1.34), and this difference was significant except for HP. NHB patients were more likely to not be offered surgery across all subsites (RR for OC, 1.38; RR for OP, 1.07; RR for HP, 1.05; RR for LX, 1.03; all P values <.05). Rates of surgery increased and rates of not being offered surgery declined for both NHB and NHW patients from 2004 to 2014, but the absolute disparities persisted in 2014. CONCLUSIONS: Across all HNSCC subsites, NHB patients were less likely than NHW patients to be recommended for and receive surgery and were more likely to refuse surgery. These differences have closed over time but persist. Enhanced shared decision making may improve these disparities.

Failed larynx preservation and survival in patients with advanced larynx cancer.

PURPOSE: To evaluate the survival benefit of total laryngectomy (TL) after induction chemotherapy in locally advanced laryngeal cancer patients. MATERIALS AND METHODS: This is a retrospective study utilizing the National Cancer Database, which captures >80% of newly diagnosed head and neck squamous cell carcinoma cases in the United States. We included patients diagnosed with advanced stage laryngeal squamous cell carcinoma between 2004 and 2013 (n = 5649) who received either TL (n = 4113; 72.8%) or induction chemotherapy followed by either radiation therapy (n = 1431) or TL (n = 105). Kaplan-Meier curves and Cox proportional hazards regression were used to evaluate overall survival. A Cox regression model was computed to examine how the prognostic impact of treatment differed by clinical stage. RESULTS: In multivariable analysis, when compared to patients receiving TL alone, those receiving induction chemotherapy followed by TL experienced no significant difference in survival (HR 0.85, 95% CI 0.63-1.13), while those receiving induction chemotherapy followed by radiation experienced poorer survival (HR 1.15, 95% CI 1.06-1.26). Induction chemotherapy followed by TL was associated with improved survival compared to induction chemotherapy and radiation (P = .042). Among patients with T4a tumors, TL (P < .001) and induction chemotherapy followed by TL (P = .002) were both associated with improved survival compared to induction chemotherapy and radiation. There were no survival differences between TL and induction chemotherapy followed by TL (HR 0.76, 95% CI 0.52-1.10). CONCLUSIONS: Larynx preservation may be attempted without compromising survival in patients with locally advanced larynx cancer who fail induction chemotherapy and undergo TL.

Two-year prevalence of dysphagia and related outcomes in head and neck cancer survivors: An updated SEER-Medicare analysis.

BACKGROUND: The aim of the study was to examine prevalence of dysphagia at the population level in head and neck cancer (HNC) survivors. METHODS: Surveillance, Epidemiology, and End Results-Medicare claims among 16 194 patients with HNC (2002-2011) were analyzed to estimate 2-year prevalence of dysphagia, stricture, and aspiration pneumonia, and derive treatment- and site-specific estimates. RESULTS: Prevalence of dysphagia, stricture, pneumonia, and aspiration pneumonia was 45.3% (95% confidence interval [CI]: 44.5-46.1), 10.2% (95% CI: 9.7-10.7), 26.3% (95% CI: 25.6-26.9), and 8.6% (95% CI: 8.2-9.1), respectively. Dysphagia increased by 11.7% over the 10-year period (P < .001). Prevalence was highest after chemoradiation and multimodality therapy. CONCLUSION: Comparing to published rates using similar methodology the preceding decade (1992-1999), prevalence of dysphagia based on claims data was similar in 2002-2011 in this study. These results suggest persistence of dysphagia as a highly prevalent morbidity, even in the decade in which highly conformal radiotherapy and minimally invasive surgeries were popularized.

Association of Facility Volume With Positive Margin Rate in the Surgical Treatment of Head and Neck Cancer.

Importance: The achievement of complete tumor resection with tumor-free margins is one of the main principles of oncologic surgery for head and neck squamous cell carcinoma (HNSCC). The negative prognostic influence of a positive margin (PM) across all head and neck subsites has been well established. National guidelines recommend the use of adjuvant chemoradiation therapy (CRT) in the setting of PM. Objective: To determine the incidence of PM in HNSCC across multiple subsites, as well as the factors associated with its occurrence. Design, Setting, and Participants: This retrospective cohort study used the National Cancer Database to identify patients diagnosed with HNSCC between 2010 and 2014 and who underwent surgical resection (n = 28 840). Main Outcomes and Measures: Predictors of PM rate and likelihood to receive adjuvant CRT. Results: Among the 28 840 patients included in this study, 19 727 (68.4 %) were men, and the average age was 62.4 years (range, 40 to ≥90 years). In univariable analysis, a lower PM rate was associated with higher facility volume (26.3% for the lowest volume quartile, 16.5% for the middle 2 quartiles, and 10.8% for the highest volume quartile) and treatment at academic vs nonacademic facilities (14.0% vs 22.7%). In multivariate analysis, those treated at higher-volume facilities remained significantly less likely to have PM (adjusted odds ratio, 0.85; 95% CI, 0.83-0.88). The trend of decreasing PM rate with increasing facility volume was observed in both academic (aOR, 0.88 per 10-case volume increase [95% CI, 0.85-0.91]) and nonacademic (aOR, 0.73 per 10-case volume increase [95% CI, 0.68-0.80]) facilities. There was no association between facility volume and patient likelihood of receiving adjuvant CRT in the setting of PM (compared with CCPs: aOR, 0.98 per 10-case volume increase [95% CI, 0.84-1.14] for CCCPs; and aOR, 1.24 [95% CI, 0.99-1.55] for INCPs). Conclusions and Relevance: These findings suggest that high-volume facilities are associated with lower rates of PM in the surgical treatment of HNSCC in both academic and nonacademic settings. Facility volume for head and neck oncologic surgeries may be considered a benchmark for quality of care.

Racial disparities in the choice of definitive treatment for squamous cell carcinoma of the oral cavity.

BACKGROUND: Definitive surgery is recommended for oral cavity squamous cell carcinoma (SCC). The purpose of this study was to present our assessment of the disparities in treatment selection for oral cavity SCC. METHODS: Non-Hispanic white and non-Hispanic black patients with oral cavity SCC were identified in the National Cancer Database (NCDB). Regression models were used to estimate relative risk (RR) of receiving surgery and absolute difference between non-Hispanic white and non-Hispanic black patients. RESULTS: There were 82.3% of non-Hispanic white patients who received surgery, compared to 64.2% of non-Hispanic black patients (P < .001). The non-Hispanic black patients were less likely to receive surgery than non-Hispanic white patients (RR 0.87) with an absolute difference of 10.9%. The non-Hispanic black patients were significantly more likely to not be offered surgery (RR 1.42) and to refuse recommended surgery (RR 1.38) but not have a contraindication to surgery (RR 1.17). CONCLUSION: The non-Hispanic black patients are less likely to receive or be recommended surgery for oral cavity SCC and are more likely to refuse surgery. Further study is needed to identify strategies to close this disparity.

Association of a Proactive Swallowing Rehabilitation Program With Feeding Tube Placement in Patients Treated for Pharyngeal Cancer.

Importance: A proactive speech and language pathology (SLP) program is an important component of the multidisciplinary care of patients with head and neck squamous cell carcinoma (HNSCC). Swallowing rehabilitation can reduce the rate of feeding tube placement, thereby significantly improving quality of life. Objective: To evaluate the initiation of a proactive SLP rehabilitation program at a single institution and its association with rates of feeding tube placement and dietary intake in patients with HNSCC. Design, Setting, and Participants: Cohort study at a tertiary care and referral center for patients with HNSCC serving the northern Chicago region. Patients were treated for squamous cell carcinomas of the hypopharynx, oropharynx, and nasopharynx from 2004 to 2015 with radiation or chemoradiation therapy in the definitive or adjuvant setting. Patients who received less than 5000 cGy radiation or underwent reirradiation were excluded. Interventions: A proactive SLP program for patients with HNSCC was initiated in 2011. Study cohorts were divided into 2 groups: 2004 through 2010 and 2011 through 2015. Main Outcomes and Measures: Primary outcome variables were SLP referral placement and timing of the referral. Secondary outcomes were feeding tube placement and ability to tolerate any oral intake. Results: A total of 254 patients met inclusion criteria (135 before and 119 after implementation of SLP program; median age, 60 years [range, 14-94 years]; 77% male). With the initiation of a proactive SLP program, pretreatment evaluations increased from 29 (21.5%) to 70 (58.8%; risk ratio [RR], 2.74; 95% CI, 1.92-3.91), and rate of referral overall at any time increased from 60.0% to 79.8% (RR, 1.33; 95% CI, 1.13-1.57). Feeding tube placement rates decreased from 45.9% (n = 62) to 29.4% (n = 35; RR, 0.64; 95% CI, 0.46-0.89). Among patients receiving a swallow evaluation, feeding tube requirements were less frequent for those receiving a pretreatment evaluation (31 of 99 [31%]) than for those referred during (11 of 18 [61%]) or after (38 of 59 [64%]) treatment. The rate of tolerating any oral intake at the end of treatment improved from 71.1% (n = 96) in the preimplementation period to 82.4% (n = 98; RR, 1.16; 95% CI, 1.01-1.33). Conclusions and Relevance: A proactive SLP program can be successfully established as part of the multidisciplinary care of patients with HNSCC and improve patient quality of life.

Ideal Characteristics of a Laser-Protected Endotracheal Tube: ABEA and AHNS Member Survey and Biomechanical Testing.

OBJECTIVES: To determine the characteristics of laser-protected endotracheal tubes (LPETs) valued by otolaryngologists performing transoral laser surgery in the head and neck and to measure LPET stiffness. METHODS: An online questionnaire was completed by American Broncho-Esophagological Association (ABEA) and American Head and Neck Society (AHNS) members. LPET distal end compliance was measured in a biomechanics laboratory. RESULTS: A total of 228 out of 2109 combined ABEA and AHNS members completed the survey. The following LPET characteristics, which were properties of the Medtronic Laser-Shield II tube (MLST), were highly valued: softness and flexibility, surface smoothness, and a tight-to-shaft balloon (all P < .01). Prior to industry-driven discontinuation of the MLST, 52% of surgeons (78% of fellowship-trained laryngologists [FTLs]) reported using it; afterward, 58% reported using the stainless steel, Mallinckrodt Laser-Flex tube (MLFT). Forty-six percent of all respondents (69% of FTLs) did not consider cost being a factor in LPET choice. Biomechanical testing revealed the distal end of the MLST to be 3.45 times more compliant than the MLFT ( P < .01). CONCLUSION: Members of the ABEA and AHNS, particularly FTLs, highly value distinguishing properties of the now discontinued MLST. Manufacturers should consider this in the design of new LPETs.
