Utility of Elective Neck Dissection in Clinically Node-Negative Parotid Malignancy.

OBJECTIVE: We sought to investigate the utility of elective neck dissection (END) in clinically node-negative parotid malignancy through the evaluation of factors that are associated with receiving END and survival analysis of patients who received END. STUDY DESIGN: Retrospective cohort database study. SETTING: The National Cancer Database (NCDB). METHODS: The NCDB was used to extract patients with clinically node-negative parotid malignancy. END was defined as having 5 or more lymph nodes examined pathologically, as previously defined in the literature. Univariate and multivariate analyses were used to compare predictors of receiving END, rates of occult metastasis, and survival. RESULTS: Of the 9405 included patients, 3396 (36.1%) underwent an END. END was most frequently performed for squamous cell carcinoma (SCC) and salivary duct histology. All other histologies were significantly less likely to undergo END compared to SCC (p < .05). Salivary ductal carcinoma and adenocarcinoma had the greatest rates of occult node disease (39.8% and 30.0%, respectively), followed by SCC (29.8%). Kaplan-Meier survival analysis showed a statistically significant increase in 5-year overall survival in patients who received END with poorly differentiated mucoepidermoid (56.2% vs 48.5%, p = .004) along with moderately and poorly differentiated SCC (43.2% vs 34.9%, p = .002; 48.9% vs 36.2%, p < .001, respectively). CONCLUSION: Histological classification is a benchmark for determining which patients should receive an END. We demonstrated an increase in overall survival in patients who undergo END with poorly differentiated tumors of mucoepidermoid and SCC histology. As such, histology should be considered along with clinical T-stage and rate of occult nodal metastasis to determine eligibility for END.

Percutaneous Endoscopic Gastrostomy Tube Timing in Head and Neck Cancer Surgery.

OBJECTIVE: To examine outcomes and complications in patients receiving a percutaneous endoscopic gastrostomy (PEG) tube on the same day of head and neck cancer (HNC) surgery versus later in hospitalization. METHODS: The 2003-2014 Nationwide Inpatient Sample was queried for patients undergoing ablative HNC procedures who had a PEG tube placed. Cases were stratified by PEG tube timing into an early (on the same day as ablative procedure) and late (later in hospitalization) group. Demographics and outcomes were compared using univariate analysis and multivariate regression modeling. RESULTS: A total of 4,068 cases were included, of which 2,206 (54.23%) underwent early PEG and 1,862 (45.77%) received a late PEG tube. Late PEG tube patients were more likely to have a diagnosis of malnutrition (18.0% vs. 15.3%, p = 0.018) or renal failure (4.7% vs. 3.0%, p = 0.006). On multivariate regression analysis, patients receiving late PEG tubes were more likely to experience aspiration pneumonia, acute pulmonary disease, infectious pneumonia, sepsis, hematoma, wound disruption, surgical site infection, and fistula formation (all p < 0.05). The mean length of stay and hospital charges in the late PEG group were significantly greater (17.1 vs. 12.6 days, p < 0.001) and ($159,993 vs. $125,705, p < 0.001), respectively. CONCLUSIONS: Patients undergoing HNC surgery who received a PEG tube on the day of ablative surgery had lower complication rates, shorter length of stay, and decreased hospital costs compared to those who had a PEG tube placed later during hospitalization. Further research is needed to determine the causal relationships behind these findings. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:109-115, 2023.

Effect of Hospital Safety Net Burden on Survival for Patients With Sinonasal Squamous Cell Carcinoma.

OBJECTIVE: To examine factors associated with hospital safety net burden and its impact on survival for patients with sinonasal squamous cell carcinoma (SNSCC). STUDY DESIGN: Retrospective database study. SETTING: National Cancer Database from 2004 to 2016. METHODS: SNSCC cases were identified in the National Cancer Database. Hospital safety net burden was defined by percentage of uninsured/Medicaid patients treated, namely ≤25% for low-burden hospitals, 26% to 75% for medium-burden hospitals, and >75% for high-burden hospitals (HBHs). Univariate and multivariate analyses were used to investigate patient demographics, clinical characteristics, and overall survival. RESULTS: An overall 6556 SNSCC cases were identified, with 1807 (27.6%) patients treated at low-burden hospitals, 3314 (50.5%) at medium-burden hospitals, and 1435 (21.9%) at HBHs. On multivariate analysis, Black race (odds ratio [OR], 1.39; 95% CI, 1.028-1.868), maxillary sinus primary site (OR, 1.31; 95% CI, 1.036-1.643), treatment at an academic/research program (OR, 20.63; 95% CI, 8.868-47.980), and treatment at a higher-volume facility (P < .001) resulted in increased odds of being treated at HBHs. Patients with grade III/IV tumor (OR, 0.70; 95% CI, 0.513-0.949), higher income (P < .05), or treatment modalities other than surgery alone (P < .05) had lower odds. Survival analysis showed that hospital safety net burden status was not significantly associated with overall survival (log-rank P = .727). CONCLUSION: In patients with SNSCC, certain clinicopathologic factors, including Black race, lower income, treatment at an academic/research program, and treatment at facilities in the West region, were associated with treatment at HBHs. Hospital safety net burden status was not associated with differences in overall survival.

Analysis of the Treatment and Survival of Sinonasal Extramedullary Plasmacytoma.

BACKGROUND: While extramedullary plasmacytomas are infrequently encountered plasma cell malignancies, most cases occur in the head and neck, with a predilection for the sinonasal cavity. Due to the rarity of this disease, the majority of studies on sinonasal extramedullary plasmacytoma (SN-EMP) are case reports or small retrospective case series. OBJECTIVE: To investigate the impact of patient, disease, and treatment factors on the survival of patients with SN-EMP. METHODS: The National Cancer Database was queried for all patients with SN-EMP between 2004-2016 (N = 381 cases). Univariate and multivariate analyses were used to examine patient demographics, tumor characteristics, and survival. RESULTS: The majority of SN-EMP patients were over 60 years old (57.0%), male (69.8%), and white (86.2%). The most common treatment modality was radiotherapy alone (38.6%), followed by surgery plus radiotherapy (37.8%). Five-year overall survival was 74.0% and median survival was 9.1 years. Accounting for patient demographics and tumor characteristics in a multivariate model, the following groups had worse prognosis: 60 and older (HR 1.99, p = 0.031) and frontal sinus primary site (HR 11.56, p = 0.001). Patients who received no treatment (HR 3.89, p = 0.013), chemotherapy alone (HR 5.57, p = 0.008) or radiotherapy plus chemotherapy (HR 2.82, p = 0.005) had significantly lower survival than patients who received radiotherapy alone. Patients who received surgery with radiotherapy (HR 0.57, p = 0.039) had significantly higher survival than patients who received radiotherapy alone. CONCLUSION: In patients with SN-EMP five-year overall survival was found to be 74.0% with decreased survival associated with a frontal sinus primary site and being aged 60 or older. Patients receiving no treatment, chemotherapy alone, or radiotherapy with chemotherapy was associated with lower survival. Receiving surgery plus radiotherapy was associated with the highest five-year overall survival.

Trends in HPV Testing for Patients With Sinonasal Squamous Cell Carcinoma: A National Analysis.

OBJECTIVE: The objective of this study was to analyze national trends in human papillomavirus (HPV) testing for patients diagnosed with sinonasal squamous cell carcinoma (SNSCC). STUDY DESIGN: Retrospective database study. SETTING: National Cancer Database (2010-2016). METHODS: Cases from 2010 to 2016 with a primary SNSCC diagnosis and known HPV testing status were extracted from the National Cancer Database. Univariate and multivariate analyses were then performed to assess differences in socioeconomic, hospital, and tumor characteristics between tested and nontested patients. RESULTS: A total of 2308 SNSCC cases were collected, with 1210 (52.4%) HPV tested and 1098 (47.6%) not tested. On univariate analyses, patient age, insurance, income quartile, population density, treatment facility location, and tumor grade were significantly associated with HPV testing status. After multivariate logistic regression modeling, living in a suburban area had lower odds of HPV testing as compared with living in urban areas (odds ratio, 0.74 [95% CI, 0.55-0.99]; P = .041), while tumor grade III/IV had higher odds than grade I (odds ratio, 1.73 [95% CI, 1.29-2.33]; P < .001). HPV-tested patients had a similar 5-year overall survival to nontested patients (48.3% vs 45.3%, log-rank P = .405). A sharp increase in HPV testing rates was observed after 2010 (P < .001). CONCLUSION: Among patients with SNSCC, those with high-grade tumors were more likely to be tested for HPV, while patients with a suburban area of residence were less likely. Additionally, there was no significant survival benefit to HPV testing, with tested and nontested groups having similar overall survival. LEVEL OF EVIDENCE: 4.

Patterns of Care and Outcomes of Primary Adenoid Cystic Carcinoma of the Trachea.

OBJECTIVE: Primary tracheal malignancies are relatively rare cancers, representing 0.1% to 0.4% of all malignancies. Adenoid cystic carcinoma (ACC) is the second most common histology of primary tracheal malignancy, after squamous cell carcinoma. This study aims to analyze demographic characteristics and potential influencing factors on survival of tracheal ACC (TACC). METHODS: This was a retrospective cohort study utilizing the National Cancer Database (NCDB). The NCDB was queried for all cases of TACC diagnosed from 2004 to 2016 (n = 394). Kaplan-Meier (KM) and Cox proportional-hazards models were used to determine clinicopathological and treatment factors associated with survival outcomes. RESULTS: Median age of diagnosis was 56 (IQR: 44.75-66.00). Females were affected slightly more than males (53.8% vs 46.2%). The most prevalent tumor diameter range was 20 to 39 mm (34.8%) followed by greater than 40 mm in diameter (17.8%). Median overall survival (OS) was 9.72 years with a 5- and 10-year OS of 70% and 47.5%, respectively. Localized disease was not associated with a survival benefit over invasive disease (P = .388). The most common intervention was surgery combined with radiation therapy (RT) at 46.2%, followed by surgery alone (16.8%), and standalone RT (8.9%). When adjusting for confounders, surgical resection was independently associated with improved OS (HR 0.461, 95% CI 0.225-0.946). Tumor size greater than 40 mm was independently associated with worse OS (HR 2.808; 95% CI 1.096-7.194). CONCLUSION: Our data suggests that surgical resection, possibly in conjunction with radiation therapy, is associated with improved survival, and tumor larger than 40 mm are associated with worse survival.

The Relationship Between Open Access Article Publishing and Short-Term Citations in Otolaryngology.

OBJECTIVES: The purpose of this study is to compare the number of citations received by open access articles versus subscription access articles in subscription journals in the Otolaryngology literature. METHODS: Using the Dimensions research database, we examined articles indexed to PubMed with at least 5 citations published in 2018. Articles were included from Otolaryngology-Head and Neck Surgery, The Laryngoscope, JAMA Otolaryngology-Head and Neck Surgery, Annals of Otology, Rhinology, and Laryngology, and American Journal of Otolaryngology. Multivariate Poisson regression modeling was used to adjust for journal, article type, and topic. Practice guidelines, position statements, or retractions were excluded as potential outliers. RESULTS: 137 open access articles and 337 subscription access articles meeting inclusion criteria were identified, with a median citation number of 8 (IQR 6-11). The most common article type was original investigation (82.5%), and the most common study topic was head and neck (28.9%). Open access articles had a higher median number of citations at 9 (IQR 6-13) when compared to subscription access articles at 7 (IQR 6-10) (P = .032). Open access status was significantly associated with a higher number of citations than subscription access articles when adjusting for journal, article type, and topic (ß = .272, CI 0.194-0.500, P < .001). CONCLUSIONS: Although comprising a minority of articles examined in this study of subscription journals, open access articles were associated with a higher number of citations than subscription access articles. Open access publishing may facilitate the spread of novel findings in Otolaryngology.

Inpatient Sinus Surgery Patient Morbidity and Outcomes: A National Analysis.

OBJECTIVES/HYPOTHESIS: To investigate the morbidity and mortality of patients undergoing endoscopic sinus surgery (ESS) in the inpatient setting. STUDY DESIGN: Retrospective database review. METHODS: The Nationwide Inpatient Sample was queried for all ESS between 2008 and 2014. Using All Patients Refined Diagnosis Related Groups (APR-DRG) codes, cases with APR-DRG codes under Major Diagnostic Category 3 (Diseases and Disorders of the Ear, Nose, Mouth, and Throat) were designated as patients with primary otolaryngology diagnoses undergoing ESS (ORL), and all other codes were designated as patients with non-otolaryngology pathologies as their primary reason for admission but undergoing ESS (non-ORL). A univariate analysis and a logistic regression were used to compare patient demographics, comorbidities, disease severity, and mortality. RESULTS: There were 8,305 ORL patients and 6,342 non-ORL patients. ORL patients were more likely to be elective admissions (61.3% vs. 48.5%, P < .001), have a deviated nasal septum (17.9% vs. 12.3%, P < .001), nasal polyps (15.8% vs. 5.0%, P < .001), obstructive sleep apnea (10.7% vs. 5.2%, P < .001), and pulmonary disease (15.9% vs. 10.5%, P < .001). Non-ORL patients had a higher likelihood of in-hospital mortality (odds ratio [OR] 6.22, 95% confidence interval [CI] 3.29-11.78, P < .001), length of stay in the highest quartile (OR 2.43, 95% CI 2.16-2.74, P < .001), and a higher proportion had APR-DRG subclasses indicating extreme severity of illness (19.3% vs. 4.3%, P < .001) or extreme risk of mortality (12.5% vs. 2.0%, P < .001). CONCLUSION: Patients undergoing ESS in the inpatient setting have a higher than expected mortality rate which can be associated with a non-otolaryngology pathology as the primary reason for their admission.

Factors Associated With Unanticipated Admission After Outpatient Endoscopic Sinonasal Surgery.

OBJECTIVES/HYPOTHESIS: To identify factors that may increase the risk of unplanned admission following elective outpatient endoscopic sinonasal surgery (ESS). STUDY DESIGN: Retrospective analysis of the National Surgical Quality Improvement Program (NSQIP). METHODS: All cases of ESS were extracted from the 2010 to 2018 NSQIP database using Current Procedural Terminology codes. Only cases coded as outpatient, elective, and nonemergent procedures were included. Unplanned admissions were defined as cases with a total hospital stay of 1 day or more. Univariate and multivariate analyses were performed to identify variables that independently predicted unanticipated admission. RESULTS: A total of 971 cases met inclusion criteria, of which 274 (28.2%) were unanticipated admissions. Patients in the unplanned admission group were more likely to be older (46.8 vs. 41.1 years, P < .001), male (57.7% vs. 48.4%, P = .009), obese (54.8% vs. 43.8%, P = .003), and have hypertension (35.0% vs. 25.0%, P = .002). Unplanned admitted patients were also more likely to be included under American Society of Anesthesiologists (ASA) classification III-IV (43.1% vs. 27.2%, P < .001). There were no significant differences in race, smoking, diabetes, or chronic steroid use. Unplanned admitted patients had a higher rate of surgical complications (2.9% vs. 1.0%, P = .041). Upon multivariate analysis, independent preoperative risk factors for unplanned admission included age (OR: 1.018, P = .002), male gender (OR: 1.415, P = .025), obesity (OR: 1.527, P = .008), and ASA III-IV (OR 1.501, P = .018). CONCLUSIONS: Factors independently associated with unplanned admission following outpatient ESS were older age, male gender, obesity, and higher ASA. Identification of patients at risk may reduce unanticipated hospital admission after ESS. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:518-522, 2022.

Exploratory analysis on the association of mental health disorders with in-hospital postoperative complications and mortality in head and neck cancer surgery.

BACKGROUND: The objective was to assess the association of mental health disorders with in-hospital complication and mortality rates in patients undergoing head and neck cancer surgery. METHODS: In this exploratory retrospective study, the Nationwide Inpatient Sample was queried from 2003 to 2014 for all patients with a diagnosis of head and neck cancer who underwent surgery. Univariate cross-tabulation, logistic regression, and propensity score matching (PSM) were used to compare demographics, procedure-related variables, and in-hospital postoperative complications and mortality between patients with and without selected comorbid mental health disorders. RESULTS: Of 39 600 included patients, 3390 (8.6%) had a selected comorbid mental health disorder diagnosis. After PSM, patients with selected mental health disorders had increased risk of overall medical complications on multivariable analysis (OR 1.28 [CI 1.12-1.46], P < 0.001) but not overall surgical complications or mortality. CONCLUSIONS: Patients with a mental health disorder diagnosis have increased risk of in-hospital medical, certain surgical, and total complications.

Clinicopathologic characteristics of laryngeal chondrosarcoma: An analysis of the National Cancer Database.

OBJECTIVES: Laryngeal Chondrosarcoma (LC) is a rare malignancy with limited studies documenting its clinicopathologic characteristics and treatment options. This study reports demographic and clinical determinants of outcomes for this rare tumor. METHODS: The National Cancer Database (NCDB) was queried for cases of LC reported from 2004-2016. 274 cases that met inclusion criteria were analyzed for demographic and clinicopathologic characteristics. Kaplan-Meier (KM) and Cox proportional hazard analyses were conducted to identify variables that impacted the overall survival of these patients. RESULTS: LC was found to be more common in males (74.8%). The mean age of patients was 61.8 years and 92.3% of the patients were white. 91.3% of patients were treated with only surgical resection, most commonly: partial laryngectomy (31.6%), total laryngectomy (25.7%), and local resection (22.4%). 98.8% of patients had no evidence of nodal disease and 99.6% of patients did not have distant metastasis at presentation. KM analysis revealed a 5-year overall survival (5YOS) of 89.0%. Age, insurance status, facility type, and surgery type were significant predictors of 5YOS (p<0.05). On Cox Proportional Hazard analysis, private insurance significantly improved survival (HR 0.21; p = 0.048) while increasing age was a poor prognostic indicator (HR 1.10; p = 0.004). CONCLUSION: The majority of LC patients present with no nodal involvement or distant metastasis at diagnosis, and overall this tumor has a favorable prognosis. Increasing age was found to be a poor prognostic factor while private insurance status was associated with improved survival.

Evaluating YouTube as a Resource for Trigeminal Neuralgia Patient Education.

PURPOSE: The objective of this study was to examine the educational value of YouTube as a source of patient information regarding trigeminal neuralgia and its treatment. We also sought to determine the degree of bias that is present in the top videos regarding this condition. MATERIALS AND METHODS: We selected 6 search terms related to trigeminal neuralgia to examine on YouTube for quality and bias using the DISCERN criteria. Filtering by relevance and total view count, we determined the top 20 results for each search term and evaluated all videos for overall educational quality and creator bias. We categorized the type of content creator and compared overall DISCERN scores and bias scores between creator type and search term. RESULTS: There were 80 unique and 40 duplicate videos. There were 10,745,574 total views across all videos, with an average view count of 89,546. The mean DISCERN score for all videos was 1.7, and the mean bias score was 2.2. Based on individual search terms, the highest mean DISCERN score was for trigeminal neuralgia surgery (2.1) and the highest mean bias score was for tic douloureux (2.8). Among creator types, medical professionals had significantly higher overall (2.2) and bias (2.6) scores. CONCLUSIONS: Overall, YouTube is a relatively poor source of unbiased information about trigeminal neuralgia. Among the existing content, medical professionals provide educational material that is the highest quality and the most unbiased.

Septic Arthritis of the Temporomandibular Joint: A Systematic Review.

PURPOSE: The purpose of this study was to describe the characteristics of the patient history, clinical findings, laboratory tests, treatment, and long-term function of septic arthritis of the temporomandibular joint (SATMJ). METHODS: All articles in the English literature related to SATMJ were queried using PubMed, Embase, and the Cochrane Library (1950 to July 1, 2020). The reference lists were reviewed for additional articles. RESULTS: A preliminary search of the literature returned 241 results, of which 37 met inclusion criteria, with an additional article from reference review. There were 93 total cases, with a mean age of 35.7 years (0.1 to 85). Symptoms mostly consisted of pain in the temporomandibular joint/preauricular region (n = 84, 90.3%), trismus (n = 73, 78.5%), and facial/preauricular swelling (n = 68, 73.1%). Most patients had no systemic symptoms (n = 80, 86.1%). The mean degree of mouth opening was 13.1 mm (5 to 35). Diagnosis was made with the following imaging modalities: radiograph (n = 48, 51.6%), CT scan (n = 35, 37.6%), MRI (n = 25, 26.9%), and ultrasound (n = 3, 3.2%). Staphylococcus aureus (n = 19, 20.4%) was most commonly isolated. About 92 patients (98.9%) received antibiotics and 85 patients underwent surgery (eg, arthrocentesis, arthroscopy, etc.), of which 15 patients (17.6%) required repeat surgery. Most long-term outcomes were favorable. Sequelae occurred in 26 of 85 patients (30.6%) with documented follow-up. CONCLUSIONS: SATMJ should be suspected in the presence of trismus, jaw pain, and preauricular swelling. Management includes prompt evaluation and treatment with broad-spectrum antibiotics. Surgery is not always indicated but can be life-saving in severe cases.

Otologic Manifestations of Eosinophilic Granulomatosis With Polyangiitis: A Systematic Review.

OBJECTIVE: To perform a systematic review of the diagnosis, treatment, and management of patients with otologic manifestations of eosinophilic granulomatosis with polyangiitis. DATABASES REVIEWED: PubMed, Embase, Cochrane. METHODS: A systematic search for relevant published literature in PubMed, Cochrane Library, and EMBASE databases was done. Data was collected on demographics, otologic manifestations, specific diagnostic criteria fulfilled, common clinical, and imaging findings as well as medical and surgical treatments received. RESULTS: Fifteen articles encompassing 219 patients met inclusion criteria including 8 case reports and 7 case series. The mean age was 52.8 (range of 24-70). The most common otologic presenting symptoms were hearing loss (76%), otitis media with effusion (44%), vertigo (22%), tinnitus (21%), and chronic otitis media (20%). The most common diagnostic criteria observed in these patients were paranasal sinus abnormalities (75%), asthma (66%), and eosinophilia >10% (44%). The most common treatment was systemic steroids (66%), followed by surgery (52%), with myringotomy with tube insertion (M&T) (32%) and endoscopic sinus surgery (21%) being the most prevalent. Thirty-four percent of patients received an immunosuppressive agent. Successful treatments included systemic steroids (23%), surgical modalities (13%) with M&T being the most common (7%), topical nasal steroids (12%), and cyclophosphamide (10%). CONCLUSION: Hearing loss and a middle ear effusion are the most common presenting otologic manifestations of eosinophilic granulomatosis with polyangiitis. Sinonasal disease was more prevalent in patients with otologic manifestations. Primary treatment consists of systemic steroids and immunomodulation. M&T, endoscopic sinus surgery, and local steroid administration can be adjunctive measures to alleviate local disease.Level of Evidence: Level 1.

Extranodal Extension as an Indicator for Sinonasal Squamous Cell Carcinoma Prognosis.

OBJECTIVE: Although extranodal extension (ENE) is a known indicator of poor prognosis for head and neck malignancies, its value as an indicator for sinonasal squamous cell carcinoma (SCC) has not been well characterized. This study seeks to assess the usefulness of ENE as a prognostic marker for sinonasal SCC. STUDY DESIGN: Retrospective database review. SETTING: National Cancer Database from 2010 to 2015. METHODS: The National Cancer Database was queried from 2010 to 2015 for all patients with sinonasal SCC with available ENE status (n = 355). These cases were divided into those with pathologically confirmed ENE (n = 146) and those without ENE (n = 209). Univariate and multivariate analyses were used to examine survival differences and predictors of ENE status. RESULTS: Most patients with ENE were ≥60 years old (61.7%), male (61.6%), and white (83.6%). Patients aged 60 to 69 and 80+ years were more likely to have ENE than those under 60 years (P < .05). Patients with ENE had worse 1-year overall survival than those without ENE (58.2% vs 70.8%, log-rank P = .008). After multivariate regression, however, there was no survival difference detected between ENE-positive and ENE-negative cases (hazard ratio, 1.14 [0.775-1.672], P = .508). CONCLUSION: ENE status did not have a significant effect on survival in patients with sinonasal SCC. Thus, ENE alone may not necessarily be a helpful indicator for sinonasal SCC prognosis.

Geographic and Socioeconomic Factors on Survival in Esthesioneuroblastoma.

OBJECTIVES: Esthesioneuroblastoma (ENB) is a rare sinonasal malignancy with little known regarding how regional and socioeconomic differences in the United States alter disease survival. The aim of this study is to explore the geographic difference in clinical features, socioeconomic factors, and survival outcomes of ENB patients. METHODS: ENB cases were extracted from the Surveillance, Epidemiology, and End Results registry from 1975-2016. Patient data were stratified based on geographical location and comparative analyses of socioeconomic features, disease characteristics, and survival patterns were performed. Kaplan-Meier regression analyses were used to estimate disease-specific survival (DSS). RESULTS: A total of 987 patients were identified: 56.4% West, 14.0% South, 12.7% Midwest, and 16.6% East. The West had the highest proportion of patients with Medicaid coverage (P < .001), stage A malignancy (P < .001), and treated with surgery and adjuvant radiotherapy (P < .001). The South had the highest proportion of patients who were Black (P < .001), uninsured (P < .001), and resided in rural areas (P < .001). Five-year DSS patterns were 81.0% (West), 79.8% (East), 67.4% (Midwest), and 72.7% (South) [P = .018]. Ten-year DSS outcomes were 74.0% (West), 73.7% (East), 60.9% (Midwest), and 63.6% (South) [P = .017]. CONCLUSION: In ENB patients, survival disparity exists in the United States based on geographical region. Patients from the West and East exhibit higher survival than those from the South and Midwest. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E2162-E2168, 2021.

Systematic Review of Negative Pressure Pulmonary Edema in Otolaryngology Procedures.

OBJECTIVE(S): Negative pressure pulmonary edema (NPPE) is a rare perioperative complication with a potentially fatal outcome. The aim of this study was to perform a systematic review of NPPE in adult otolaryngology procedures with the goal of identifying risk factors, clinical presentation, diagnosis, management and outcomes. METHODS: Systematic review performed using PubMed, Scopus, Web of Science, and Cochrane databases. RESULTS: Sixty-nine studies including data from 87 individual patients were included in this review. Fifty-six (68%) patients were male and the average patient age was 37 years old. Type 1 NPPE occurred in 63 (72%) cases, while type 2 NPPE accounted for 20 (23%) cases. The most common procedures leading to NPPE were septoplasty, rhinoplasty or sinus surgery (n = 22, 25%), directly laryngoscopy or bronchoscopy (n = 13, 15%), and tracheostomy or cricothyroidotomy (n = 11, 13%). The most employed treatment options included diuretics (n = 55, 63%) and mechanical ventilation (n = 54, 62%). Seventy-eight (90%) patients made a full recovery with an average time to NPPE resolution of 33 hours and an average length of hospitalization of 5.6 days. Five (6%) patients had a long-term morbidity and four (5%) patients died, with age and ICU stay increasing risk for death and long-term morbidity (OR 1.044 and 7.42, respectively, P < .05). CONCLUSION: Septoplasty, rhinoplasty and sinus surgery account for the majority of NPPE cases in adult otolaryngology procedures. Young, healthy patients are the most commonly involved with a slight male predominance. The vast majority of patients recover fully, however there is a significant risk for morbidity and mortality.

Comparison of Open and Endoscopic Approaches in the Resection of Esthesioneuroblastoma.

BACKGROUND: Olfactory neuroblastoma, or esthesioneuroblastoma (ENB), is an uncommon sinonasal malignancy arising from olfactory neuroepithelium that is optimally treated with surgical resection. The objective of this study is to determine preoperative predictors of undergoing open versus endoscopic approach for ENB and to investigate significant postoperative survival outcomes between the two surgical approaches. METHODS: The National Cancer Database (NCDB) was queried for cases of ENB histology that were treated surgically from 2010 to 2015. Groups were stratified into open or endoscopic approach cohorts. Patient demographics, tumor characteristics, treatment modality, and 5-year overall survival were compared between the two groups using Chi-Square analysis and Kaplan-Meier survival analysis. Cases were classified as Kadish stage A, B, C, or D based on the "Collaborative Stage-Extension" codes in NCDB. RESULTS: Of 533 patients meeting inclusion criteria, 276 (51.8%) patients underwent open, and 257 (48.2%) patients underwent endoscopic surgical approaches. Patients undergoing endoscopic surgery were more likely to be Kadish stages A and B and less likely to be stages C and D (P = .020). Those undergoing endoscopic approach overall had a shorter mean hospital stay postoperatively (3.8 vs. 7.0 days, P < .001). Endoscopic cases had a greater 5-year overall survival (81.9% vs. 75.6%, P = .030); after multivariate regression, there was a trend toward survival benefit to endoscopic surgery that did not reach clinical significance (HR 0.644, [0.392-1.058], P = .083). CONCLUSION: Although not statistically significant, there is a trend toward increased overall survival with an endoscopic approach in patients undergoing surgery for ENB as compared to an open approach, regardless of Kadish stage. An endoscopic approach is an adequate alternative to an open approach for the surgical treatment of ENB.
