A position statement put forth by the American Head and Neck Society (AHNS) was constructed to provide evidence-based treatment recommendations for PD-1 inhibitor use in advanced cutaneous squamous cell carcinoma (cSCC). Secondarily, we sought to identify knowledge gaps warranting further investigation.A literature search utilizing key terms: cutaneous squamous cell carcinoma, cutaneous cancer, checkpoint inhibitors, systemic therapy, Program Cell Death, PD-1 (PubMed, Cochrane, and Google Scholar) was carried out to generate evidence-based statements. The statements were distributed among the AHNS membership. Delphi methodology was applied to identify statements achieving 70% or greater consensus among the leadership team.Twenty-six position statements achieved consensus. Knowledge gaps for future research included: impact of immunosuppression on cSCC staging and associated treatment; role of PD-1 inhibitors in immunosuppressed patients.This comprehensive position statement put forth by the AHNS represents majority consensus by practicing head and neck surgeons throughout the country.

Background Anosmia and ageusia are symptoms commonly associated with COVID-19, but the relationship with disease severity, onset and recovery are unclear. Objective To examine factors associated with anosmia and ageusia and the recovery from these symptoms in an ethnically diverse cohort. Methods Individuals tested for SARS-CoV-2 between March and April 2020 were eligible for the study. Randomly selected participants answered a telephone questionnaire on COVID-19 symptoms with a focus on anosmia and ageusia. Additionally, relevant past medical history and data on the COVID-19 clinical course were obtained from electronic medical records. 486 patients were in the COVID-19 group and 103 were COVID-19-negative. Results Patients who were younger were more likely to report anosmia and/or ageusia (odds ratio (OR) for anosmia per 1-year increase in age: 0·98, 95%CI:0–97-0·99, p = 0·003; for ageusia: 0·98, 95%CI:0·97-0·99, p = 0·005) as were patients with lower eosinophil counts (OR for anosmia per 0.1-K/μL increase in eosinophils: 0·02, 95%CI:0·001-0·46, p = 0·01, for ageusia 0·10, 95%CI:0·01-0·97, p = 0·047). Male gender was independently associated with a lower probability of ageusia (OR:0·56, 95%CI:0·38-0·82, p = 0·003) and earlier sense of taste recovery (HR:1·44, 95%CI:1·05-1·98, p = 0·02). Latinos showed earlier sense of taste recovery than white patients (HR:1·82, 95%CI:1·05-3·18, p = 0·03). Conclusion Anosmia and ageusia were more common among younger patients and those with lower blood eosinophil counts. Ageusia was less commonly reported among men, and time to taste recovery was earlier among both men and Latinos.

Various risk stratification systems for cytologically indeterminate thyroid nodules are available. However, malignancy risk assessment data, such as ultrasound features, are not always used when the decision is to order molecular testing or not. Our aim was to investigate the utility of molecular testing after incorporating an algorithm with ultrasound-based risk of malignancy (ROM) estimation.Diagnostic/prognostic study.Single-institution urban tertiary care center.We performed a single-institution retrospective chart review of all thyroid nodules that had undergone molecular testing. A web-based Malignancy Risk Estimation System for Thyroid Nodules was utilized with ultrasound findings to stratify malignancy risk according to the Korean Thyroid Imaging Reporting and Data System (TI-RADS), French TI-RADS, American Association of Clinical Endocrinology guideline, and American Thyroid Association guideline. A novel algorithm for utilizing molecular testing at our institution was developed with the Korean TI-RADS and with recommendations from the American Thyroid Association and National Comprehensive Cancer Network.The Korean TI-RADS performed best in our population (area under the curve = 0.83). A positive molecular test result had a positive association with a higher ROM according to all 4 models (In patients with indeterminate thyroid nodules, an algorithm built on pre- and posttest probability to guide molecular testing might reduce unnecessary testing of benign and low-risk nodules.

OBJECTIVES/HYPOTHESIS The objective of this study was to examine the association between modality of primary treatment and survival among patients with locoregionally advanced hypopharyngeal cancer. STUDY DESIGN Retrospective cohort. METHODS There were 2,328 adult patients diagnosed with stage III or IV, M0, hypopharyngeal squamous cell carcinoma identified within the Surveillance, Epidemiology and End Results (SEER) registry (years 2004-2015). Patients who received primary chemoradiation (CRT) were compared to those who received surgery with either adjuvant radiation therapy (S + RT), or surgery with adjuvant CRT (S + CRT). The latter primary surgery group (S + Adj) was also analyzed collectively. Overall survival (OS) and disease-specific survival (DSS) were assessed using Kaplan-Meier analyses and Cox regression models using a propensity score to adjust for factors associated with treatment allocation. RESULTS Median survival was 20 months (interquartile range [IQR] = 10-45) with CRT and 25 months (IQR = 10-47) with S + Adj (P

BACKGROUND The Bethesda System standardized the reporting of thyroid cytopathology and created categories to provide an estimation of a nodule's risk of malignancy. There are limited data describing their utility in different racial-ethnic groups. METHODS A retrospective chart review of thyroid fine-needle aspirations (FNA) was performed within our health-care systems. Sensitivity, specificity, positive predictive value (PPV), and negative predictive values (NPVs) were calculated for the total cohort, and racial-ethnic groups. RESULTS The sensitivity, specificity, PPV, and NPV of the entire cohort was 93%, 77%, 57%, and 97%. Among patients who underwent surgery, African Americans contained a high number of Bethesda II FNAs (63%) compared to Hispanics (48%) and whites (45%). The sensitivity, specificity, and NPV were comparable among groups, the PPV was lowest for African Americans (43%), followed by Hispanics (60%) and whites (69%). CONCLUSIONS The Bethesda system's predictive value may differ among racial-ethnic groups.

Background Body mass index (BMI), sarcopenia, and obesity-related comorbidities have been associated with head and neck squamous cell carcinoma (HNSCC) progression. Methods We conducted a retrospective analysis of 441 normal-weight, overweight, and obese HNSCC patients treated at Montefiore Medical Center (New York). Patients were grouped by BMI prior to treatment and assessed for differences in survival adjusting for comorbid conditions (cardiovascular disease and diabetes). Evidence of sarcopenia was also assessed using pretreatment abdominal CT scans in a subset of 113 patients. Results Prior to treatment, 55% of HNSCC patients were overweight or obese. Overweight/obese patients had significantly better overall survival (hazard ratio [HR] = 0.4, 95% CI: 0.3-0.6) compared to normal-weight patients, independent of comorbid conditions. Patients with sarcopenia had significantly poorer survival (HR = 2.1, 95% CI: 1.1-3.9) compared to non-sarcopenic patients, with the strongest association seen among overweight/obese patients. Conclusion Our data support the importance of sarcopenia assessment, in addition to BMI, among patients with HNSCC.

OBJECTIVES/HYPOTHESIS The COVID-19 pandemic has resulted in a dramatic increase in the number of patients requiring prolonged mechanical ventilation. Few studies have reported COVID-19 specific tracheotomy outcomes, and the optimal timing and patient selection criteria for tracheotomy remains undetermined. We delineate our outcomes for tracheotomies performed on COVID-19 patients during the peak of the pandemic at a major epicenter in the United States. METHODS This is a retrospective observational cohort study. Mortality, ventilation liberation rate, complication rate, and decannulation rate were analyzed. RESULTS Sixty-four patients with COVID-19 underwent tracheotomy between April 1, 2020 and May 19, 2020 at two tertiary care hospitals in Bronx, New York. The average duration of intubation prior to tracheotomy was 20 days ((interquartile range [IQR] 16.5-26.0). The mortality rate was 33% (n = 21), the ventilation liberation rate was 47% (n = 30), the decannulation rate was 28% (n = 18), and the complication rate was 19% (n = 12). Tracheotomies performed by Otolaryngology were associated with significantly improved survival (P

Objective Performing tracheotomy in patients with COVID-19 carries a risk of transmission to the surgical team due to potential viral particle aerosolization. Few studies have reported transmission rates to tracheotomy surgeons. We describe our safety practices and the transmission rate to our surgical team after performing tracheotomy on patients with COVID-19 during the peak of the pandemic at a US epicenter. Study Design Retrospective cohort study. Setting Tertiary academic hospital. Methods Tracheotomy procedures for patients with COVID-19 that were performed April 15 to May 28, 2020, were reviewed, with a focus on the surgical providers involved. Methods of provider protection were recorded. Provider health status was the main outcome measure. Results Thirty-six open tracheotomies were performed, amounting to 65 surgical provider exposures, and 30 (83.3%) procedures were performed at bedside. The mean time to tracheotomy from hospital admission for SARS-CoV-2 symptoms was 31 days, and the mean time to intubation was 24 days. Standard personal protective equipment, according to Centers for Disease Control and Prevention, was worn for each case. Powered air-purifying respirators were not used. None of the surgical providers involved in tracheotomy for patients with COVID-19 demonstrated positive antibody seroconversion or developed SARS-CoV-2–related symptoms to date. Conclusion Tracheotomy for patients with COVID-19 can be done with minimal risk to the surgical providers when standard personal protective equipment is used (surgical gown, gloves, eye protection, hair cap, and N95 mask). Whether timing of tracheotomy following onset of symptoms affects the risk of transmission needs further study.

The rapid spread of SARS‐CoV‐2 in 2019 and 2020 has resulted in a worldwide pandemic characterized by severe pulmonary inflammation, effusions, and rapid respiratory compromise. The result of this pandemic is a large and increasing number of patients requiring endotracheal intubation and prolonged ventilator support. The rapid rise in endotracheal intubations coupled with prolonged ventilation requirements will certainly lead to an increase in tracheostomy procedures in the coming weeks and months. Performing tracheostomy in the setting of active SARS‐CoV‐2, when necessary, poses a unique situation, with unique risks and benefits for both the patient and the health care providers. The New York Head and Neck Society has collaborated on this document to provide guidance on the performance of tracheostomies during the SARS‐CoV‐2 pandemic.

To examine opioid-prescribing patterns after endocrine surgery. To evaluate factors associated with postoperative pain and opioid use.Cross-sectional.Academic university health system.The study sample included 209 patients who underwent total thyroidectomy, hemithyroidectomy, or parathyroidectomy by 4 surgeons between August 2015 and November 2017. Eighty-nine patients completed a phone survey about postoperative pain and opioid use. Prescription, demographic, and comorbidity data were collected retrospectively. Patient characteristics associated with opioid use, use of ≥10 opioid pills, and pain score were identified via chi-square, t test, analysis of variance, or Pearson correlation. Identified factors were further assessed with multivariable logistic and linear regression modeling.The median numbers of opioid pills prescribed were 20 for total thyroidectomy, 25 for hemithyroidectomy, and 20 for parathyroidectomy, and the median numbers of pills used were 1.5, 2, and 0, respectively. Of 1947 total prescribed pills, 19.7% were reported to be taken. The number of pills meeting the opioid needs of 80% of these patients was 10. In multivariable analyses, older age was associated with lower odds of opioid use (odds ratio, 0.97; 95% CI, 0.94-0.999; P = .04) and lower pain scores (Pearson correlation coefficient, -0.05; 95% CI, -0.10 to 0.001, P = .04). Charlson Comorbidity Index score5 was associated with use of ≥10 pills (odds ratio, 6.62; 95% CI, 1.60-27.50; P = .01).Excess opioids are often prescribed for endocrine surgery. By using an ideal pill number and understanding predictors of postoperative pain, surgeons can more adequately treat pain and limit excess opioid prescriptions.

OBJECTIVES/HYPOTHESIS To identify compressive symptomatology in a patient cohort with benign thyroid disease who underwent thyroidectomy. To determine radiographic/clinicopathologic features related to and predictive of a compressive outcome. STUDY DESIGN Retrospective cohort study. METHODS Medical records of 232 patients with benign thyroid disease on fine needle aspiration who underwent thyroidectomy from 2009 to 2012 at an academic medical center were reviewed. Data collection and analyses involved subjects' demographics, compressive symptoms, preoperative airway encroachment, intubation complications, specimen weight, and final pathologic diagnosis. RESULTS Subjects were ages 14 to 86 years (mean: 52.4 years). Ninety-six subjects (41.4%) reported compressive symptomatology of dysphagia (n =74; 32%), dyspnea (n = 39; 17%), and hoarseness (n = 24; 10%). Ninety-seven (42.2%) had preoperative airway encroachment. Dyspnea was significantly related to tracheal compression, tracheal deviation, and substernal extension. Dysphagia was related to tracheal compression and tracheal deviation. Compressive symptoms and preoperative airway encroachment were not related to intubation complications. Final pathologic diagnosis was not related to compressive symptoms, whereas specimen weight was significantly related to dyspnea and dysphagia. Final pathology revealed 74 subjects (32%) with malignant lesions. Malignant and benign nodular subject groups differed significantly in substernal extension, gland weight, tracheal deviation, and dyspnea. Logit modeling for dyspnea was significant for tracheal compression as a predictor for the likelihood of dyspnea. CONCLUSION Dyspnea was closely related to preoperative airway encroachment and most indicative of a clinically relevant thyroid in our cohort with benign thyroid disease. Tracheal compression was found to have predictive value for the likelihood of a dyspneic outcome. LEVEL OF EVIDENCE 4. Laryngoscope, 127:993-997, 2017.

Objectives/Hypothesis Previous studies report high-accuracy rates for intraoperative frozen sections, but reliability of frozen sections in predicting the ultimate final margin status is unknown. We compared frozen and permanent reads to identify risk factors for overall discrepancies between intraoperative and final margin status. Study Design Retrospective chart review. Methods Pathology reports of 437 surgical resections between 2010 and 2013 were retrospectively reviewed. A total of 253 cases, generating 1,109 individual specimens, met inclusion criteria. Patient demographics, treatment, recurrence, and survival, as well as pathology data pertaining to the specimen, were recorded. Results Frozen read accuracy was 96.7% (83.1% sensitivity, 97.9% specificity) relative to permanent evaluation. However, 4.3% of cases had a final positive margin not detected by frozen section; 17.8% had a close margin not detected by frozen section. In eight of 11 cases with missed positive margins, the involved margin was never sampled intraoperatively. Cases where intraoperative margins were only taken from surrounding tissue had a higher risk of missing a close or positive final margin when compared to cases where some or all margins were taken from the specimen (odds ratio = 5.05, 95% confidence interval [2.31, 11.07], P

Objectives/Hypothesis Black race is a risk factor for angioedema. The primary aim was to examine the relationship between race–ethnicity and risk factors for angioedema. Study Design Using a retrospective case-control study design, data was extracted with the Clinical Looking Glass utility, a data collection and management tool that captures data from electronic medical record systems within the Montefiore Healthcare System. Cases were emergency department (ED) visits with primary or secondary International Classification of Diseases, Ninth Revision, code diagnoses of angioedema in adults aged ≥ 18 years from January 2008 to December 2013 at three Montefiore centers in Bronx, New York. Controls were a random sampling of adult ED visits during the same period. Methods In primary analyses, angiotensin-converting enzyme inhibitor (ACE-I) and black race were evaluated for synergy. The influence of different risk factors in the development of angioedema was evaluated using logistic regression models. Finally, race–ethnicity was further explored by evaluating for effect modification by stratification of models by race–ethnicity categories. Results There were 1,247 cases and 6,500 controls randomly selected from a larger control pool. ACE-I use (odds ratio [OR] 3.70, 95% confidence interval [CI] 2.98, 4.60), hypertension (OR 1.88, 95% CI 1.55, 2.29), and black race (OR 2.25, 95% CI 1.86, 2.72) were the strongest risk factors. ACE-I use and black race were not synergistic (OR 1.10, 95% CI 0.80, 1.51). Race–ethnicity was an effect modifier for certain risk factors. Conclusion Race–ethnicity acts as an effect modifier for particular angioedema risk factors. The two strongest risk factors, ACE-I use and black race, were not synergistic. Level of Evidence 3b.

To examine the prevalence of ultrarapid metabolizers of codeine among children in an ethnically diverse urban community.Cross-sectional study.A tertiary care academic children's hospital in the Bronx, New York.In total, 256 children with nonsyndromic congenital sensorineural hearing loss were analyzed. DNA was assessed for 63 previously described single-nucleotide polymorphisms (SNPs) and copy number variants (CNVs) known to alter the function and expression of the CYP2D6 gene primarily responsible for codeine metabolism. The rate of CYP2D6 metabolism was predicted based on participants' haplotype.Ethnic distribution in the study subjects paralleled recent local census data, with the largest portion (115 children, 45.8%) identified as Hispanic or Latino. A total of 154 children (80.6%) had a haplotype that corresponds to extensive codeine metabolism, 18 children (9.42%) were identified as ultrarapid metabolizers (UMs), and 16 children (8.37%) were intermediate metabolizers. Only 3 children in our cohort (1.57%) were poor metabolizers. Patients identifying as Caucasian or Hispanic had an elevated incidence of UMs (11.3% and 11.2%, respectively) with extensive variability within subpopulations.The clinically significant rate of ultrarapid metabolizers reinforces safety concerns regarding the use of codeine and related opiates. A patient-targeted approach using pharmacogenomics may mitigate adverse effects by individualizing the selection and dosing of these analgesics.

Importance Delay in time to treatment initiation (TTI) can alter survival and oncologic outcomes. There is a need to characterize these consequences and identify risk factors and reasons for treatment delay, particularly in underserved urban populations. Objectives To investigate the association of delayed treatment initiation with outcomes of overall survival and recurrence among patients with head and neck squamous cell carcinoma (HNSCC), to analyze factors that are predictive of delayed treatment initiation, and to identify specific reasons for delayed treatment initiation. Design, Setting, and Participants Retrospective cohort study at an urban community-based academic center. Participants were 956 patients with primary HNSCC treated between February 8, 2005, and July 17, 2017, identified through the Montefiore Medical Center Cancer Registry. Exposures The primary exposure was TTI, defined as the duration between histopathological diagnosis and initial treatment. The threshold for delayed treatment initiation was determined by recursive partitioning analysis. Main Outcomes and Measures Overall survival, recurrence, and reasons for treatment delay. Results Among 956 patients with HNSCC (mean [SD] age, 60.8 [18.2] years; 72.6% male), the median TTI was 40 days (interquartile range, 28-56 days). The optimal TTI threshold to differentiate overall survival was greater than 60 days (20.8% [199 of 956] of patients in our cohort). Independent of other relevant factors, patients with HNSCC with TTI exceeding 60 days had poorer survival (hazard ratio, 1.69; 95% CI, 1.32-2.18). Similarly, TTI exceeding 60 days was associated with greater risk of recurrence (odds ratio, 1.77; 95% CI, 1.07-2.93). Predictors of delayed TTI included African American race/ethnicity, Medicaid insurance, body mass index less than 18.5, and initial diagnosis at a different institution. Commonly identified individual reasons for treatment delay were missed appointments (21.2% [14 of 66]), extensive pretreatment evaluation (21.2% [14 of 66]), and treatment refusal (13.6% [9 of 66]). Conclusions and Relevance Delaying TTI beyond 60 days was associated with decreased overall survival and increased HNSCC recurrence. Identification of predictive factors and reasons for treatment delay will help target at-risk patients and facilitate intervention in hospitals with underserved urban populations.

BACKGROUND Increased detection of papillary thyroid cancer (PTC) has led to overtreatment of the largely indolent follicular variant (fvPTC). To guide management of non-aggressive lesions, we investigated whether race predicts PTC variant and tumor behavior. METHODS Analysis of 258 973 patients from the National Cancer Database diagnosed with PTC in 2004-2014. Clinical and tumor information was compared by race. Multivariate logistic regression was used to predict fvPTC, extrathyroidal extension (ETE), and lymph node metastasis (LNM) of fvPTC. RESULTS Blacks had the highest fvPTC rate (40% vs white 30%, Hispanic 26%, Asian 25%, P

Patients presenting with advanced aerodigestive malignancy and respiratory compromise often undergo tracheotomy as initial airway management. Tumor debulking is a potential alternative. We present a case series with chart review to communicate our institutional experience with this technique. T3/4 glottic and supraglottic cancers treated between 2004 and 2014 underwent review, and 14 patients were identified for this study. Of these, 5 (35.7%) required subsequent tracheotomy, and 9 (64.3%) did not. Patients requiring subsequent tracheotomy had a delay in initiating definitive treatment when compared with those who did not (83.3 vs 31.3 days, P = .0025). No patient required a tracheotomy after initiation of definitive treatment. Our experience suggests that tumor debulking may be a viable option in select patients but that a delay in initiating treatment is associated with patients requiring tracheotomy subsequent to debulking. Further research is needed to better delineate patient scenarios in which tumor debulking alone is sufficient.

This article is a continuation of the "Do You Know Your Guidelines" series, initiated by the Education committee of the American Head and Neck Society. Treatment guidelines for advanced head and neck squamous cell carcinoma are reviewed here, including the critical roles of radiotherapy, chemotherapy, and the recent application of immunotherapy agents. We will be limiting this discussion to include cancers of the oral cavity, oropharynx, hypopharynx, and larynx. It should be noted that much of the article pertains to human papillomavirus (HPV)-negative oropharyngeal cancer where applicable, as HPV-positive oropharyngeal squamous cell carcinoma carries a different natural history, different prognosis, and now different staging criteria. Additionally, the article will not include information on nasopharyngeal or sinus cancers, as these latter topics are covered in separate "Do you know your guidelines?" installments and these diagnoses carry somewhat different approaches to diagnosis and management that diverge from the focus of this article.

Objective Our objective was to compare the accuracy of preoperative positron emission tomography (PET)/computed tomography (CT) and contrast-enhanced CT (CECT) in detecting cervical nodal metastases in patients treated with neck dissection and to scrutinize the ability of each modality to determine nodal stage. Study Design Case series with chart review. Setting Montefiore Medical Center, Bronx, New York. Subjects and Methods Patients who underwent neck dissection at our institution for primary treatment of head and neck squamous cell carcinoma (HNSCC) and had received preoperative PET/CT and CECT were included in this study. Imaging studies were reinterpreted by 3 specialists within the field and compared for interreader agreement. Concordance between radiology and histopathology was measured using neck levels and sides, along with patient nodal stage. Sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and agreement coefficients were calculated. Results Seventy-three patients were included in the study. Sensitivity was 0.69 and 0.94 (level and side) for PET/CT vs 0.53 and 0.66 for CECT ( P = .056, P = .001). Specificity was 0.86 and 0.56 for PET/CT vs 0.91 and 0.76 for CECT ( P = .014, P = .024). No significant difference was found in overall accuracy ( P = .33, P = .88). The overall agreement percentages between N stage called by imaging modality and pathology were 52% and 55% for PET/CT and CECT, respectively. Conclusion No significant difference in sensitivity was found between PET/CT and CECT. CECT was found to have superior specificity compared with PET/CT. The information gleaned from each modality in the pretreatment evaluation of HNSCC appears to be complementary.

Objectives/Hypothesis To evaluate the etiology and risk factors for severe manifestation and recurrent episodes of angioedema; to evaluate efficacy of short-term and long-term management strategies for angioedema among a high-risk population. Study Design Institutional review board-approved retrospective review of a large, urban population. Methods Data from 875 adult patients treated from January 2008 to December 2013 with the diagnosis of angioedema were obtained using the Clinical Looking Glass utility and review of medical records. Demographic and clinicopathologic risk factors were recorded. The major outcomes evaluated were hospital admission, need for airway intervention, and recurrent episodes of angioedema following the first presentation. Initial treatment strategy and follow-up recommendations were also recorded. Results The most common cause of angioedema was angiotensin converting enzyme inhibitor (ACEi)-induced (496 [56.6%]). Significant risk factors for severe cases of angioedema included older age, Hispanic race, ACEi-induced angioedema type, American Society of Anesthesiologists class III or above, coexistent cardiopulmonary disease, and a positive smoking history. A total of 17.2% of patients experienced recurrent attacks of angioedema; of those patients, 25.9% were still taking an ACEi at subsequent presentation. Risk factors for recurrent episodes included older age, idiopathic angioedema type, and coexistent cardiopulmonary disease. Only 54.1% of patients who experienced ACEi-induced angioedema had electronic medical record documentation of these allergies. Conclusions Knowledge of risk factors for severe and recurrent episodes of angioedema and improved education for both healthcare providers and patients, specifically related to ACEi use and allergy documentation, may significantly decrease the burden and morbidity of angioedema among high risk populations.

Background Esthesioneuroblastoma (ENB) is derived from the specialized olfactory neuroepithelium. Hyams grading and Kadish staging have been used to prognosticate and to guide treatment decisions. In this study, we sought to validate the prognostic utility of these systems in a large ENB cohort. Methods We retrospectively analyzed the records of patients with ENB who had been evaluated and treated at our institution. The association of grade and stage with prognostic outcome was assessed; the Kaplan-Meier estimator was used to generate 5-year OS and DFS curves. Results Out of 124 cases we identified, 121 were assessed for grading and 109 for staging. Review of the tissue samples revealed that 62% of tumors were low grade (I/II) and 21% were high grade (III/IV); 17% of tumors were metastasis. The OS rate was 75% at 5 years. The DFS was 60% at 5 years. The OS was significantly worse for metastatic ENB (low-grade ENB vs metastatic ENB, p = 0.01598); the DFS was significantly worse for high grade versus low grade ENB. Of the 109 cases that had been staged, 16% were stage A, 33% stage B, 43% stage C, and 8% stage D. In the A, B, and C groups, there were no significant differences between recurrence, distant metastasis, or 5-year survival rates. Statistical significance was neither reached with T, N, M and overall staging system. Age cutoff of 65 years reliably predicted OS. Conclusions High grade of ENB was significantly associated with poor outcome, while advanced stage was not associated with poor outcome in this large cohort. Grading should certainly be considered in prognostication and treatment decisions for ENB.

Background Esthesioneuroblastoma is a rare cancer of the anterior cranial base that arises in the region of the olfactory rootlets. The purpose of this study was to review the long-term outcomes of patients diagnosed with esthesioneuroblastoma (ENB) treated at a single institution to determine factors associated with improved disease control and survival. Methods A retrospective review of 70 patients with ENB treated at the University of Texas MD Anderson Cancer Center between 1992 and 2007 was undertaken. Survival and recurrence was analyzed and compared using the Kaplan–Meier method and log-rank statistics. Results Seventy patients were reviewed. The majority (77%) had T3 or T4 disease at presentation, 38% identified as modified Kadish stage C or D. Ninety percent of patients received surgical resection as part of their treatment, and 66% received postoperative radiation or chemoradiation. The median follow-up was 91.4 months (7.6 years). Forty-eight percent of patients developed recurrent disease and the median time to recurrence was 6.9 years. Overall and disease-specific median survival was 10.5 and 11.6 years, respectively. Patients who were treated with surgery alone had a median disease-specific survival of 87.9 months, whereas those who were treated with surgery and postoperative radiation had a median disease-specific survival of 218.5 months (p = .047). Conclusion Patients with ENB can achieve favorable long-term survival, even if disease is locally advanced. Survival is improved considerably when surgical resection is followed by postoperative radiation. However, recurrence rates and mortality remain high, and therefore long-term observation in these patients is warranted. © 2013 Wiley Periodicals, Inc. Head Neck 36: 524–530, 2014

Summary Objective The aim of this study was to aid in the distinction among hyperadductive dysphonias by evaluating peak glottal pressure, release burst, and mid and final airflow values across repeated /pa/ syllable trains. Methods Sixty subjects were assessed for aerodynamic patterns during onset-offset for the /papapapapa/ task in modal voice. Subject groups included adductory spasmodic dysphonia (AdSD), benign vocal fold lesion, primary muscle tension dysphonia (MTD-1), secondary muscle tension dysphonia with an identifiable primary benign vocal fold lesion (MTD-2), vocal fold paresis or paralysis, and normal controls. Results Increased peak pressure (PP) was found for AdSD and MTD-2 subjects compared with controls. Release burst and mid airflow were not significantly different among groups. Final airflow was significantly higher for AdSD compared with the other groups. Final airflow was significantly lower for MTD-1. Conclusions Significant differences in aerodynamics are seen in subjects with AdSD compared to MTD. AdSD was characterized by higher PP and higher final airflow. MTD-1 was characterized by lower final airflow, whereas MTD-2 was characterized by higher PP. Aerodynamic evaluation may aid in differential diagnosis for those patients in whom distinction among hyperadductive disorders is challenging.

Objective: Extracapsular dissection (ECD) has become an accepted, less invasive alternative for the removal of select benign parotid lesions that may reduce complications. Minimal margin extracapsular dissection (MECD) with dissection on or closer to the tumor capsule may be a reasonable alternative to ECD. The objective of this study is to review the complications and safety of the MECD technique at a single institution. Subjects and Methods: Medical records for patients who underwent MECD for suspected benign parotid lesions were reviewed. Outcome measurements included intraoperative findings, complications, and recurrences. Results: Forty patients underwent a MECD for suspected benign parotid lesions. The average tumor size was 2.2 cm. Frozen section revealed low-intermediate grade mucoepidermoid carcinoma in 2 (5%) cases, requiring completion of a superficial parotidectomy at the same setting. There was 1 case of temporary facial nerve weakness and no cases of Frey syndrome. No tumor recurrences were observed within the follow-up period (average 3.5 years.) Conclusion: In the hands of an experienced surgeon, MECD may be a viable alternative to formal superficial parotidectomy. This study reports low rates of nerve weakness and Frey syndrome. Long-term follow-up is necessary to determine the ultimate risk of recurrence.

American Society of Anesthesiology guidelines recommend preoperative fasts of 6 hours after light snacks and 8 hours after large meals. These guidelines were designed for healthy patients undergoing elective procedures but are often applied to intubated intensive care unit (ICU) patients. ICU patients undergoing routine procedures may be subjected to unnecessary prolonged fasts. This study tests whether shorter fasts allow for better nutrition delivery and patient outcomes without increasing the risk.Randomized blinded controlled trial.Tertiary academic medical center.ICU patients undergoing bedside tracheotomy.Intubated ICU patients who were receiving enteral feeding and for whom bedside tracheotomy was indicated were enrolled prospectively and randomly allocated to 2 parallel preoperative fasting regimens: a 6-hour fast (control) and a 45-minute fast (intervention). Patients were assessed for aspiration, caloric delivery, metabolic markers, and infectious and noninfectious complications.Twenty-four patients were enrolled and randomized. There were no complications related to the procedure. There were no cases of intraoperative aspiration identified. There was a single postoperative pneumonia in the control group. Median (interquartile range) length of fast and caloric delivery were significantly different between the control group and the shortened fast group: 22 hours (18, 34) vs 14 hours (5, 25; P.001) and 429 kcal (57, 1125) vs 1050 kcal (825, 1410; P = .01), respectively.Shortening preoperative fasts in intubated ICU patients allowed for better caloric delivery in the preoperative period.

Objectives:This second segment of the two-part review summarises several modern high-throughput methods in genomics, epigenetics and molecular biology. Many principles from nucleotide sequencing and transcriptomics can be applied to other high-throughput molecular biology techniques. Specifically, this manuscript reviews: array comparative genome hybridisation; single nucleotide polymorphism arrays; microarray technology, used to study epigenetics; and methodology applied in proteomics. Finally, the review describes current methods for the integration of multiple molecular biology platforms.Conclusion:Progress in treating human disease in general will require close collaboration with experts in bioinformatics. Improved understanding, by clinicians and physician-scientists in our field, of the concepts presented in both parts of this review will advance diagnosis and therapy for diseases of the head and neck.

Objectives:Patients with angioedema present to the emergency department (ED) with myriad signs and symptoms with a wide range of severity, from mild discomfort to severe airway compromise. Initial estimation of angioedema course and patient airway safety can be challenging. Base of tongue (BOT) and laryngeal involvement are recognized to correlate with need for intubation; however, there are few clear indicators of potential future airway compromise. We evaluated the relationship between presenting signs and symptoms with fiberoptic laryngoscopic findings to help in the immediate stratification of angioedema patients.Methods:Retrospective chart review of patients presenting with angioedema to the ED of a tertiary care center from January 2005 to July 2013.Results:Of 1987 patients treated by the ED for angioedema, 401 generated an otolaryngology consult; of these, 79 (19.7%) and 128 (31.9%) had base of tongue (BOT) and laryngeal involvement, respectively. Dysphagia and voice change correlated with both BOT...

Objective: The objective was to determine patient and gland characteristics associated with difficult intubation in patients undergoing thyroidectomy for goiter and to assess different methods of intubation in these patients. Methods: This study was an IRB-approved, retrospective chart review of 112 consecutive patients undergoing hemithyroidectomy or total thyroidectomy for thyroid goiter from 2009-2012 at an academic tertiary care facility in Bronx, New York. Patient demographics, thyroid gland characteristics (gland weight and nodule size), presence of preoperative symptoms (dyspnea, dysphagia, and hoarseness), and radiographical findings (tracheal compression, tracheal deviation, and substernal extension of the thyroid gland) were recorded. Anesthesia records were reviewed for method of intubation, as well as success or failure of intubation attempts. Results: Nineteen patients (17.0%) were men and 93 (83.0%) were women. The age of the patients included in the study ranged from 14 to 86 years with a mean ± SD age of 53.5 ± 14.7 years. Difficult intubation was noted with 13 (11.6%) patients. Only patient age was significantly associated with difficult intubation. The mean age of patients with airway difficulty was 60.7 ± 3.7 years compared to 52.1 ± 1.5 years in those who did not experience airway difficulty ( P = .04). No other reviewed risk factors were found to be significantly associated with difficult intubation. Fiberoptic intubation (FOI) was used in 38 patients and difficult intubation occurred in 18.4% (7/38). Direct laryngoscopy with transoral intubation (LTOI) was used in 58 patients, in whom 3.4% (2/58) experienced a difficult intubation. FOI was aborted 6 times and LTOI was subsequently successful in each of these cases. Conclusions: Our results suggest that benign nodular goiter disease does not pose significant challenges to intubation in our patient cohort. The technique of intubation deviated from the initial plan several times in the FOI group, whereas LTOI was ultimately successful in every case. Our data suggest that the role of fiberoptic intubation for patients with large goiters should be further refined.

Background Oropharyngeal squamous cell carcinoma (OPSCC) is increasing in frequency. We reviewed patients with advanced-stage OPSCC treated with chemoradiation to assess the impact of residual neck disease on survival. Methods We reviewed 202 patients with OPSCC between 1990 and 2010 treated with primary chemoradiation followed by neck dissection. Imaging was analyzed using RECIST (Response Evaluation Criteria In Solid Tumors) 1.1 criteria. Survival was evaluated using both univariate and multivariate analyses. Results Overall survival at 5 years was 89%. Forty-two patients (21%) had residual disease in the neck (pN+). pN+ was associated with greater locoregional recurrence (LRR) and distant metastasis (DM) and decreased survival. No clinicopathologic factors were predictive of pN+. Contrasted posttreatment CT had low sensitivity and specificity. Conclusions In advanced OPSCC pN+, patients have higher rates of LRR and DM. Neither clinicopathologic factors nor posttreatment imaging was predictive of pN+, although increased use of modern imaging may reduce the rate of negative neck dissections. © 2012 Wiley Periodicals, Inc.

Objectives: The study of adenoid cystic carcinoma (ACC) of the salivary gland requires long-term follow up due to the slow growth rate of the tumor and its propensity to recur many years after therapy. Current management strategy for ACC has varied little in the last 60 years, but techniques in surgical and radiotherapy have improved. We have retrospectively studied patients with adenoid cystic carcinoma of the salivary gland during the last 25 years to determine current survival data at our institution. Methods: Forty-two patients treated for ACC of the salivary gland between 1975 and 2003 were registered at Northwestern Memorial Hospital. Kaplan-Meier analysis was used to characterize survival for this patient population. Tumor site, staging, and size of tumor were analyzed to determine their relationship to patient survival. Prognostic factors were compared to determine if each played a significant role in predicting mortality. Results: Of the 42 patients studied, 19 patients died during follow-up after receiving treatment for ACC. Twenty-three patients were alive at the date of last contact. Kaplan-Meier analysis of the 42 patients yielded a 5-year survival rate of 82.5% and a 10-year survival rate of 61%. Tumor site, stage, and size appeared to influence survival. Conclusion: Our review represents the most current assessment of survival for patients with adenoid cystic carcinoma at our institution. The data presented in our study concur with more recent literature, suggesting survival probability in patients with adenoid cystic carcinoma may be higher due to improved surgical technique and management with radiation therapy.

Case Report A 40 year-old gentleman presented to the otolaryngology office for evaluation of a left supraclavicular mass. Upon review of his history, it was found that the patient had noticed numbness of his arms, legs and trunk, which had developed 23 weeks previously. On physical examination the patient had no reflexes, tonic pupils, and orthostatic hypotension. Workup revealed that the patient had a sensorimotor polyneuropathy. He tested positive for serum anti-Hu antibodies. The patient underwent a left neck dissection including resection of the supraclavicular mass, and he was found to have a myxoid chondrosarcoma with metastases to several cervical lymph nodes. The tumor stained diffusely with anti-Hu antibodies. Since surgery, the patient has received intravenous immunoglobulin and Tacrolimus with slow progression of his neurologic disturbance.
