Cytopathologic assessment of gloves and instruments after major head and neck surgery.

PURPOSE: To investigate the potential for cancer cells to be transferred between anatomic sites via instruments and other materials. MATERIALS AND METHODS: Pilot prospective study from April 2018-January 2019 at Rush University Medical Center. Glove and instrument washings were collected from 18 high-risk head and neck cancer resection cases (36 samples total). Each case maintained at least one of the following features in addition to a diagnosis of squamous cell carcinoma or sarcoma: palliative/salvage surgery, positive margins, extensive tumor burden, and/or extra capsular extension (ECE). Surgical gloves and four main instruments were placed through washings for blind cytological assessment (2 samples/case). RESULTS: 18 patients undergoing surgical tumor resection for biopsy-proven squamous cell carcinoma with at least one of the aforementioned characteristics were included. 26.7% of cases had ECE, 40.0% had positive final margins and 46.7% had close final margins. Tumor locations included: oral cavity (10), neck (4), parotid gland (2), and skin (2). Malignant cells were isolated on glove washings in 1 case (5.5%). No malignant cells were isolated from instrument washings. The single case of malignant cells on glove washings occurred in a recurrent, invasive squamous cell carcinoma of the scalp with intracranial extension. Anucleated squamous cells likely from surgeon skin were isolated from 94.4% of washings. Squamous cells were differentiated from mature cells by the absence of nuclei. CONCLUSIONS: Malignant squamous cells can be isolated from surgical glove washings, supporting the practice of changing of gloves after gross tumor resection during major head and neck cancer resections.

Slowly progressive facial paralysis: Intraneural squamous cell carcinoma of unknown primary.

BACKGROUND: In this report, we present a unique case of intraneural squamous cell carcinoma of unknown primary found within the facial nerve and the proposed algorithms for diagnosis and management of progressive idiopathic facial paralysis. CASE PRESENTATION: A 66-year-old female with a previous history of basal cell carcinoma presented with right-sided progressive facial paralysis. Repeated magnetic resonance imaging as well as targeted workup failed to reveal a diagnosis. 20 months following symptom onset, after the patient's facial function slowly progressed to a complete paralysis, repeat magnetic resonance imaging revealed enhancement at the stylomastoid foramen. The patient underwent superficial parotidectomy, transmastoid facial nerve decompression and resection of descending and proximal extratemporal facial nerve segments, as well as great auricular nerve interposition grafting. Intraoperatively, frozen sections from the surface of the facial nerve, and the proximal and distal segments of the facial nerve following resection, were negative for malignancy. The final pathology revealed infiltrating poorly differentiated squamous cell carcinoma of the facial nerve with negative margins. CONCLUSION: In cases of slowly progressive facial paralysis the clinician needs to consider malignancy until proven otherwise. Without an identifiable primary malignancy, early algorithmic assessment of presenting characteristics may facilitate expedited clinical decision making and surgical management of malignancy involving the facial nerve. In cases of slowly progressive facial paralysis, when the time comes for surgical exploration and biopsy, head and neck surgeons must be aware that malignancy can exist entirely within the facial nerve, without pathologic changes on the surface of the nerve or in the surrounding tissue.

An Aprotinin Containing Fibrin Sealant Does Not Reduce Blood Loss in Total Hip Arthroplasty.

BACKGROUND: Fibrin sealants are topical agents used to reduce perioperative blood loss; however, their efficacy in total hip arthroplasty (THA) remains uncertain. The purpose of this study was to determine if a fibrin sealant containing aprotinin as an antifibrinolytic agent, TISSEEL (Baxter, Deerfield, IL), reduces postoperative blood loss and transfusion during THA when compared with intravenous (IV) tranexamic acid (TXA) and control groups. METHODS: Three retrospective uniform cohorts of primary THA procedures were identified, from a prospectively maintained database: 1 group who received TISSEEL, 1 group who received 1 g IV TXA, and 1 group who received neither (control). There were 80 patients in each group. Outcome measures included the lowest measured hemoglobin during postoperative hospitalization, greatest decrease in hemoglobin from preoperative to postoperative values, and blood transfusion rates. RESULTS: The minimum postoperative hemoglobin level was significantly lower for TISSEEL patients compared with that of IV TXA patients (P = .021) and no different when compared with that of control patients (P = .134). Patients receiving fibrin sealant had a greater hemoglobin level decrease compared with that of IV TXA (P = .029) and control (P = .036). Postoperative transfusion rates were no different for the group receiving TISSEEL compared with those of control (P = .375) and were statistically greater when compared with those of IV TXA (P = .002). CONCLUSION: TISSEEL fibrin sealant does not reduce postoperative blood loss or transfusions; however, IV TXA reduced postoperative transfusions compared with TISSEEL and control. Therefore, TXA is recommended to reduce perioperative blood loss, while, utilization of a fibrin sealant requires further refinements before being adopted for routine use in THA.

Prevention and Management of Complications in Nasal Reconstruction.

Nasal reconstruction is a challenging practice with the potential for complications. Surgeons can prevent complications through preoperative optimization of patient factors, refinement of intraoperative surgical techniques, and postoperative surgical and nonsurgical wound care. Preoperatively, optimization of modifiable and recognition of nonmodifiable risk factors is paramount. Intraoperatively, meticulous flap design and surgical technique promote healing. In the postoperative setting, attentive wound care, adjuvant therapies, and close follow-up for consideration of additional procedures enhance outcomes. By anticipating potential complications across perioperative settings, surgeons can prevent common complications in nasal reconstruction and more effectively manage those complications that arise.

Difficult Airway Response Team (DART) and Airway Emergency Outcomes: A Retrospective Quality Improvement Study.

OBJECTIVE: Difficult airways can be associated with significant morbidity and mortality, particularly in the event of a delay in securing the airway. To improve the airway metrics at our institution, we implemented a multidisciplinary team of airway providers to respond to difficult and emergent airways, or the Difficult Airway Response Team (DART). The purpose of the present study is to assess the feasibility of a DART program at a tertiary care center. STUDY DESIGN: A retrospective study evaluating the outcomes of emergent airway cases using the DART protocol. SETTING: Single tertiary academic care center. METHODS: In August 2019, a DART program was implemented at a tertiary academic medical center. In order to assess the feasibility and effectiveness of this system, data were collected to assess DART outcomes through chart review and surveys following each event, and analyzed in Microsoft Excel. RESULTS: A total of 161 DART events (average 4.6/month) took place from August 2019 to June 2022. Anesthesiologists secured the airway in 71 events (51%), otolaryngologists in 38 (27%), and pulmonary/critical care in 12 (9%). Seventy-three activations were not labeled as a difficult airway. Pre-DART, 19 cases required more than 3 attempts to secure the airway compared to 11 cases after DART. Transoral intubation was the most common intervention. Thirteen cases required surgical intervention. CONCLUSION: Implementing a multidisciplinary team-based approach for managing emergent difficult airways at a tertiary care institution was feasible and resulted in a decreased number of airway attempts in difficult airway patients. Continuous process improvement is essential for the ongoing enhancement of DART systems.

Hypothyroidism as an Independent Predictor of 30-day Readmission in Head and Neck Cancer Patients.

OBJECTIVES: To define the role of hypothyroidism and other risk factors for unplanned readmissions after surgery for head and neck cancer. STUDY DESIGN: Retrospective cohort study. METHODS: The Nationwide Readmission Database (NRD) was used to identify patients who underwent surgery for mucosal head and neck cancer (oral cavity, oropharynx, larynx, and hypopharynx) between 2010 and 2017. Univariate and multivariate logistic regression were performed to determine patient, tumor, and hospital related risk factors for 30-day readmission. Readmitted patients were stratified by preoperative diagnosis of hypothyroidism to compare readmission characteristics. RESULTS: For the 131,013 patients who met inclusion criteria, the readmission rate was 15.9%. Overall, 11.91% of patients had a preoperative diagnosis of hypothyroidism. After controlling for other variables, patients with a preoperative diagnosis of hypothyroidism had 12.2% higher odds of readmission compared to those without hypothyroidism (OR: 1.12, 1.03-1.22, p = 0.008). Patients with hypothyroidism had different reasons for readmission, including higher rates of wound dehiscence, fistula, infection, and electrolyte imbalance. Among readmitted patients, the length of stay for index admission (mean 10.5 days vs. 9.2 days, p < 0.001), readmission (mean 7.0 vs. 6.6 days, p = 0.05), and total hospital charge were higher for hypothyroid patients ($137,742 vs. $119,831, p < 0.001). CONCLUSION: Hypothyroidism is an independent risk factor for 30-day readmission following head and neck cancer resection. Furthermore, hypothyroid patients are more likely to be readmitted for wound complications, infection, and electrolyte imbalance. Targeted interventions should be considered for hypothyroid patients to decrease readmission rates and associated patient morbidity, potentially leading to earlier initiation of adjuvant treatment.

Defining the Allergic Endotype of Chronic Rhinosinusitis by Structured Histopathology and Clinical Variables.

BACKGROUND: Atopy has a strong association with chronic rhinosinusitis (CRS). OBJECTIVE: To understand whether patients with atopy and CRS can be defined by markers of tissue histopathology, systemic biomarkers, and clinical factors, which may guide their response to new pharmacologic agents. METHODS: In a retrospective cohort of CRS patients who underwent functional endoscopic sinus surgery, a structured histopathology report consisting of 12 variables, comorbid conditions, preoperative total serum IgE levels, and preoperative modified Lund-Kennedy endoscopic and sinonasal outcome test (SNOT-22) scores were compared between atopic CRS (aCRS) and non-aCRS control patients in a multivariable model. RESULTS: A total of 380 CRS patients were enrolled, 286 of whom had comorbid atopy (aCRS). Compared with non-aCRS, aCRS patients had significantly higher preoperative total SNOT-22 scores (40.45 ± 22.68 vs 29.70 ± 20.68, P = .015) and symptom-specific SNOT-22 scores in all domains except psychological dysfunction. Relative to non-aCRS, aCRS patients had increased tissue eosinophilia (P < .0001), eosinophil aggregates (P < .0001), Charcot-Leyden crystals (P < .04), fibrosis (P < .02), total serum IgE levels (P < .04), polyploid disease (P < .001), and a prevalence of comorbid asthma (P < .0001) and aspirin exacerbated respiratory disease (AERD) (P < .003). Patients with aCRS demonstrated increased tissue eosinophilia compared with non-aCRS patients even after controlling for polypoid disease, asthma, and AERD. CONCLUSION: In the context of CRS, atopy appears to be a specific predictor of CRS severity linked to specific histopathologic variables, including enhanced eosinophilic aggregates. Moving forward, allergic status may be a useful way to identify an atopic endotype of CRS patients. Furthermore, after surgery, patients are often maintained on intranasal corticosteroids. In patients whose disease is unresponsive to steroids, we may look to atopic status to identify another management therapy. Atopic CRS patients, irrespective of polyp and asthmatic status, could be optimal candidates for biologic agents such as T-helper cell, eosinophil, and/or IgE-targeted therapies.

Otolaryngology in the Time of Corona: Assessing Operative Impact and Risk During the COVID-19 Crisis.

OBJECTIVE: Limited research exists on the coronavirus disease 2019 (COVID-19) pandemic pertaining to otolaryngology-head and neck surgery (OHNS). The present study seeks to understand the response of OHNS workflows in the context of policy changes and to contribute to developing preparatory guidelines for perioperative management in OHNS. STUDY DESIGN: Retrospective cohort study. SETTING: Pediatric and general adult academic medical centers and a Comprehensive Cancer Center (CCC). SUBJECTS AND METHODS: OHNS cases from March 18 to April 8, 2020-the 3 weeks immediately following the Ohio state-mandated suspension of all elective surgery on March 18, 2020-were compared with a 2019 control data set. RESULTS: During this time, OHNS at the general adult and pediatric medical centers and CCC experienced 87.8%, 77.1%, and 32% decreases in surgical procedures as compared with 2019, respectively. Aerosol-generating procedures accounted for 86.8% of general adult cases, 92.4% of pediatric cases, and 62.0% of CCC cases. Preoperative COVID-19 testing occurred in 7.1% of general adult, 9% of pediatric, and 6.9% of CCC cases. The majority of procedures were tiers 3a and 3b per the Centers for Medicare & Medicaid Services. Aerosol-protective personal protective equipment (PPE) was worn in 28.6% of general adult, 90% of pediatric, and 15.5% of CCC cases. CONCLUSION: For OHNS, the majority of essential surgical cases remained high-risk aerosol-generating procedures. Preoperative COVID-19 testing and intraoperative PPE usage were initially inconsistent; systemwide guidelines were developed rapidly but lagged behind recommendations of the OHNS department and its academy. OHNS best practice standards are needed for preoperative COVID-19 status screening and PPE usage as we begin national reopening.

Approximate Weight of 1:1000 Topical Epinephrine on Wrung-Out Epinephrine-Soaked Pledgets.

OBJECTIVE: Topical 1:1000 epinephrine solution is commonly applied intranasally with cottonoid pledgets in endoscopic sinonasal surgery for local vasoconstriction and hemostasis. Pledgets are typically submerged in epinephrine solution and applied without measurement. Hemodynamic complications have been reported when pledgets have been saturated and not wrung out. The amount of epinephrine absorbed per pledget has not been studied methodically. The purpose of this study was to determine the amount of topical 1:1000 epinephrine remaining on a cottonoid pledget after wringing out the pledget, to simulate intraoperative application. STUDY DESIGN: Cohort study. SETTING: Tertiary care center. SUBJECTS AND METHODS: Sixty 0.5-in × 3-in cottonoid pledgets were submerged in canisters filled with 1:1000 epinephrine solution (1 mg/mL). Weights of the epinephrine-filled canisters were measured before submerging the pledgets and then after removing and wringing out the pledgets. Measurements were recorded for each pledget after being submerged for 0, 1, and 5 minutes and then wrung out. Mean weights were calculated and compared between the submersion durations. RESULTS: The mean overall weight of epinephrine on a wrung-out pledget was 0.931 mg. Mean weights of epinephrine absorbed onto wrung-out pledgets after submersion for 0, 1, and 5 minutes were 0.914, 0.913, and 0.967 mg, respectively. There were no significant differences in weights based on submersion duration (P = .296). CONCLUSION: Approximately 1 mg of epinephrine was absorbed onto 0.5-in × 3-in cottonoid pledgets when pledgets were wrung out after being submerged in 1:1000 epinephrine, whether being removed from solution immediately or after up to 5 minutes.

The Impact of Laryngopharyngeal Reflux on Patient-reported Measures of Chronic Rhinosinusitis.

OBJECTIVE: This study explored the impact of laryngopharyngeal reflux (LPR) on quality-of-life outcomes captured by Sino-Nasal Outcome Test (SNOT-22) and Reflux Symptom Index (RSI) in patients with chronic rhinosinusitis (CRS) and patients with symptoms of LPR. METHODS: In a retrospective chart review, SNOT-22 and RSI scores were analyzed in patients seen at a tertiary care center with CRS, LPR, or both CRS and LPR. SNOT-22 items were grouped into sleep, nasal, otologic, and emotional symptom subdomains. RESULTS: A total of 138 patients (36 with CRS alone, 60 with LPR alone, and 42 with both CRS and LPR) were included. Compared to patients with CRS alone, those with CRS and LPR (CRS+LPR) had higher SNOT-22 total (50.54 ± 19.53 vs 35.31 ± 20.20, P < .001), sleep (19.61 ± 9.31 vs 14.42 ± 10.34, P < .022), nasal (17.38 ± 7.49 vs 11.11 ± 8.52, P < .001), otologic subdomains (9.17 ± 5.07 vs 5.53 ± 5.14, P < .002), and RSI (22.06 ± 9.42 vs 10.75 ± 8.43, P < .003). Patients with LPR alone had higher RSI compared to those with CRS (18.48 ± 9.77 vs 10.75 ± 8.43, P < .037). RSI and SNOT-22 scores were positively correlated irrespective of patient group (R = 0.289, P = .003). CONCLUSION: Compared to patients with CRS or LPR alone, those with CRS+LPR demonstrated higher RSI and total and subdomain SNOT-22 scores. Patients with LPR alone had elevated SNOT-22 despite absent endoscopic evidence of sinusitis.

Histopathologic Influences of Comorbid Smoking Status in Chronic Rhinosinusitis.

BACKGROUND: Smoking status has been established as a known irritant of the upper and lower respiratory tracts, leading to inflammation throughout the respiratory system. Tobacco smoking is one comorbidity encountered among chronic rhinosinusitis (CRS) patients. The histopathologic features of CRS and comorbid smoking status have yet to be determined by structured histopathology and may have important implications on disease management. METHODS: Retrospective study of structured histopathology reports analyzing sinus tissue removed during functional endoscopic sinus surgery. Histopathology variables were compared among patients with CRS who were reported as never smokers, former smokers, or current smokers. RESULTS: A total of 285 CRS patients were included: 173 never smokers, 85 former smokers, and 27 current smokers. When compared with former smokers, current smokers demonstrated increased basement membrane thickening (88.9% vs 67.1%, P <.020). Compared with never smokers, former and current smokers collectively demonstrated increased hyperplastic changes (14.3% vs 6.9%, P < .035), increased squamous metaplasia (26.8% vs 17.3%, P < .040), and trends toward increased basement membrane thickening (72.3% vs 65.3%, P < .124) and increased fibrosis (47.3% vs 40.5%, P < .154). CONCLUSION: Smoking status may influence histopathologic tissue-level changes in CRS disease. Interestingly, former and current smokers maintained few differences in histopathology. However, former and current smokers collectively demonstrated increased chronic inflammatory changes compared with never smokers. These findings suggest that the timing of smoking exposure has limited effect on the tissue level, rather exposure overall influences inflammatory change. These findings may have important implications on medical and surgical management of CRS disease and comorbid smoking status.

The Association of Serum Eosinophilia with Structured Histopathology in Chronic Rhinosinusitis.

BACKGROUND: Prior studies have demonstrated associations between serum eosinophilia and chronic rhinosinusitis (CRS) pathogenesis. However, the association of serum eosinophilia with histopathology profiling in CRS has not been fully delineated and may help better characterize CRS disease burden prior to surgery. METHODS: A structured histopathology report of 13 variables was utilized to analyze sinus tissue removed during functional endoscopic sinus surgery (FESS). Complete blood count (CBC) with differential was drawn within 4 weeks prior to FESS. Serum eosinophilia was defined as >6.0% (>0.60 th/µL). Histopathology variables were compared among patients. RESULTS: A total of 177 CRS patients (37 with serum eosinophilia and 140 with normal serum eosinophilia) were analyzed. Compared to CRS patients with normal serum eosinophil counts, CRS patients with serum eosinophilia demonstrated increased polypoid disease (67.6% vs 35.0%, P < .001), eosinophil aggregates (45.9% vs 20.7%, P = .003), and eosinophils per high-power field (>5/HPF) (67.6% vs 40.7%, P = .003). CONCLUSION: CRS patients with serum eosinophilia demonstrated severe disease burden on histopathology with high levels of polypoid disease and tissue eosinophilia. However, a considerable number of patients without serum eosinophilia demonstrated eosinophilic disease on histopathology, indicating that preoperative serum eosinophilia alone could not be reliably used to predict eosinophilic CRS.

Survival in low-grade and high-grade sinonasal adenocarcinoma: A national cancer database analysis.

OBJECTIVES/HYPOTHESIS: The purpose of this study was to investigate survival differences between low-grade and high-grade sinonasal adenocarcinoma (SNAC) by examining demographics, tumor characteristics, and treatment modalities. STUDY DESIGN: Retrospective database analysis. METHODS: The National Cancer Database was queried for patients with SNAC between 2004 and 2015. Univariate and multivariate analyses were performed for all cases of SNAC. Subsequent analysis focused on low-grade (grade 1 and grade 2) and high-grade (grade 3 and grade 4) SNAC. RESULTS: A total of 1,288 patients with SNAC were included in the main cohort and divided into low grade (n = 601) and high grade (n = 370). The 5-year overall survival for all patients, low-grade, and high-grade was 54%, 64%, and 38%, respectively. Prognostic factors associated with decreased survival for the main cohort include advanced age (hazard ratio [HR]: 1.04; 95% confidence interval [CI]: 1.03-1.06), Charlson-Deyo score (HR: 1.37; 95% CI: 1.05-1.78), grade 2 (HR: 2.21; 95% CI: 1.26-3.86], grade 3 (HR: 3.67; 95% CI: 2.09-6.45), and grade 4 (HR: 3.31; 95% CI: 1.38-7.91). Radiotherapy was associated with improved overall survival for high-grade SNAC (HR: 0.41; 95% CI: 0.24-0.70) but not for low-grade SNAC (HR: 1.05; 95% CI: 0.59-1.85). CONCLUSIONS: This investigation is the largest to date analyzing the association of treatment modalities with overall survival in SNAC. Surgery remains paramount to treatment, with radiotherapy offering additional survival benefit for high-grade SNAC. Administration of chemotherapy was not associated with improved survival.

Treatment modalities in sinonasal mucosal melanoma: A national cancer database analysis.

OBJECTIVES/HYPOTHESIS: The purpose of this study was to investigate the association of demographic factors, tumor stage, and treatment modalities for overall survival in patients with sinonasal mucosal melanoma (SNMM). STUDY DESIGN: Retrospective database review. METHODS: The National Cancer Database was queried for patients of all ages with SNMM between 2004 and 2015. Univariate Kaplan-Meier and multivariate Cox regression analyses were performed to evaluate the association of suspected prognostic factors with overall survival. RESULTS: A total of 1,874 patients with SNMM were included in the analysis. The 5-year overall survival was 24%. Prognostic factors associated with decreased survival include advanced age (hazard ratio [HR]: 1.02, 95% confidence interval [CI]: 1.01-1.03), T4 disease (HR: 1.44, 95% CI: 1.09-1.89), and presence of distant metastases (HR: 3.22. 95% CI: 2.06-5.04). Improved survival was associated with surgical resection only when margins were negative (HR: 0.44; 95% CI: 0.30-0.65). In patients with metastatic disease, administration of immunotherapy (HR: 0.14; 95% CI: 0.04-0.49) was associated with improved survival. Surgical approach, radiotherapy, and chemotherapy were nonsignificant predictors of survival. CONCLUSIONS: This investigation is the largest to date to analyze the association of treatment modalities with overall survival in SNMM. Surgery remains the mainstay of treatment in patients with SNMM. However, administration of immunotherapy may confer survival benefit to patients with metastatic disease. LEVEL OF EVIDENCE: NA Laryngoscope, 130:275-282, 2020.

Effect of margin status and pathological grade in treatment of sinonasal mucoepidermoid carcinoma.

OBJECTIVES: The purpose of this study was to investigate the association of demographic factors, grade, margin status, and treatment modalities for overall survival in patients with sinonasal mucoepidermoid carcinoma (SNMEC). STUDY DESIGN: Retrospective database review. METHODS: The National Cancer Database was queried for patients of all ages with SNMEC between 2004 and 2015. Univariate Kaplan-Meier and multivariate Cox regression analyses were performed to evaluate the association of suspected prognostic factors with overall survival. Subgroup analysis by margin status and grade was performed. RESULTS: A total of 239 patients with SNMEC were included in the analysis. The 5-year overall survival was 63.6%. Prognostic factors associated with decreased survival include age over 70 years (P = .027), sphenoid primary site (P = .002), and advanced-stage malignancy (P = .024). Improved survival was associated with surgery achieving negative margins (P = .001). Adjuvant radiation was associated with improved survival (hazard ratio [HR] = 0.25, P = .015) in the negative-margin group but was not found to be a statistically significant factor in the positive-margin group (HR = 0.66, P = .509). CONCLUSIONS: This investigation is the largest to date to analyze the association of treatment modalities with overall survival in SNMEC and subgroup analysis by histopathologic grade and surgical margin status of treatment outcomes. Surgery remains the mainstay of treatment in patients with SNMEC. However, administration of radiation may confer survival benefit to patients with negative margins.

Chronic rhinosinusitis precipitated by tumor necrosis factor alpha inhibitors is the phenotype of chronic rhinosinusitis without nasal polyps.

BACKGROUND: Chronic rhinosinusitis (CRS) is a frequently observed condition in patients with immunodeficiency secondary to tumor necrosis factor alpha inhibitors (TNFαis). The histologic features of CRS caused by TNFαis have yet to be determined and may have important implications in understanding the pathophysiology of the disease process. METHODS: A structured histopathology report was used to analyze sinus tissue removed during functional endoscopic sinus surgery (FESS). These structured histopathology variables were compared among patients with CRS on TNFαi (CRSαi), CRS without nasal polyps (CRSsNP) patients, and CRS with nasal polyps (CRSwNP) patients. RESULTS: Eighteen CRSαi, 91 CRSwNP, and 113 CRSsNP patients undergoing FESS were analyzed. Compared to CRSsNP, CRSαi patients exhibited increased mucosal ulceration (16.7% vs 0.9%, p < 0.008), increased fibrosis (100% vs 34.5%, p < 0.001), and increased presence of Charcot-Leiden crystals (16.7% vs 0%, p < 0.002). Compared to CRSwNP, CRSαi patients demonstrated increased fibrosis (100% vs 54.9%, p < 0.001), decreased presence of subepithelial edema (44.4% vs 69.2% p < 0.043), decreased eosinophil aggregates (22.2% vs 47.3% p < 0.042), and fewer eosinophils per high-power field (44.4% vs 73.6%, p < 0.017). CONCLUSION: CRSαi exhibits structured histopathology more similar to CRSsNP. In the appropriate clinical context, it may be reasonable that the medical regimen for these patients be focused on a more antineutrophilic, macrolide-based approach. This study provides insight into the inflammatory environment of patients with CRSαi and may have implications for disease management.

Histopathologic Features of Chronic Sinusitis Precipitated by Odontogenic Infection.

BACKGROUND: Chronic rhinosinusitis (CRS) is a heterogeneous disease process that can arise in the context of odontogenic disease from the maxillary teeth. The histopathologic features of odontogenic CRS (CRSo) have yet to be determined and may have important implications on disease management and need for escalation of therapy. OBJECTIVES: The objectives of this study are to characterize the histopathologic features of CRSo and determine whether the inflammatory profile of CRSo contributes to its recalcitrance to medical therapy and need for surgery in a subset of patients with this disease. METHODS: A structured histopathology report was used to analyze sinus tissue removed during functional endoscopic sinus surgery (FESS). Histopathology variables, Lund-Mackay scores (LMS), and Sinonasal Outcome Test-22 scores were compared among CRSo patients, CRS without nasal polyps (CRSsNP) patients, and CRS with nasal polyps (CRSwNP) patients. RESULTS: Twenty-three CRSo, 38 CRSwNP, and 53 CRSsNP patients who underwent FESS were analyzed. Compared to CRSsNP, CRSo exhibited increased moderate-severe inflammation (73.9% vs 41.5%, P < .009). Compared to CRSwNP, CRSo had decreased squamous metaplasia (0.0% vs 18.4%, P < .03) and decreased fibrosis (26.1% vs 63.2%, P < .005). Eosinophilia was prevalent in CRSo but to a lesser extent than in CRSwNP (39.1% vs 63.2%, P < .05). CRSo cases had significantly lower mean LMS compared to CRSwNP (7.83 ± 2.77 vs12.18 ± 6.77, P < .005). CONCLUSION: CRSo exhibits histopathologic features similar to those of CRSsNP with more severe inflammation. Moreover, eosinophilia, which is not typically considered to coexist with CRSo, was present in a large portion of CRSo patients. These findings may help explain at the inflammatory level why select cases of CRSo may be recalcitrant to medical and dental therapy.

The impact of race and insurance status on baseline histopathology profile in patients with chronic rhinosinusitis.

BACKGROUND: Chronic rhinosinusitis (CRS) is an inflammatory disease process characterized by different phenotypes and histopathology profiles. Race and access to care have been implicated in CRS disease severity. Structural histopathology reporting may aid in delineating the inflammatory burden responsible for this effect. METHODS: A structured histopathology report of 14 variables was utilized to assess sinus tissue removed during functional endoscopic sinus surgery (FESS). Histopathology variables and 22-item Sino-Nasal Outcome Test (SNOT-22) scores were compared by race (Black, White, Latino, and Asian) and insurance status (Medicare, Medicaid, and private insurance). RESULTS: A total of 201 CRS patients (124 White, 38 Black, 28 Latino, and 9 Asian) undergoing FESS were included. Black patients demonstrated increased SNOT-22 scores (50.74 ± 20.32 vs 41.47 ± 22.75, p < 0.022) and number of eosinophils per high-power field (>5/HPF) (60.5% vs 44.8%, p < 0.05). White patients demonstrated decreased eosinophil aggregates (22.6% vs 35.1%, p < 0.039) and eosinophils/HPF (<5/HPF) (42.7% vs 55.8%, p < 0.048). Medicaid patients showed increased SNOT-22 score (55.50 ± 24.46 vs 41.39 ± 21.74, p < 0.003), polypoid disease (61.5% vs 42.3%, p < 0.05), subepithelial edema (80.8% vs 53.1%, p < 0.006), hyperplastic/papillary changes (23.1% vs 8.0%, p < 0.028), fibrosis (61.5% vs 38.5%, p < 0.036), eosinophil aggregates (46.2% vs 24.6%, p < 0.022), and eosinophils/HPF (>5/HPF) (65.4% vs 45.1%, p < 0.043). When controlling for insurance status, Black race was no longer associated with increased SNOT-22 (p < 0.104) or eosinophils/HPF (>5/HPF) (p < 0.183). CONCLUSION: Black and Medicaid patients demonstrated more severe disease by histopathology and SNOT-22 scores. These findings were no longer significant among Black patients after adjusting for insurance status, suggesting that the prevailing factor influencing worse disease may be access to care.

The presence of eosinophil aggregates correlates with increased postoperative prednisone requirement.

OBJECTIVES/HYPOTHESIS: Failure after sinus surgery is multifactorial, but often due to recurrence of inflammatory mucosal disease. Postoperative steroid requirements for controlling mucosal inflammation may provide insight into predicting which patients require more aggressive medical therapy to prevent disease relapse. STUDY DESIGN: Retrospective chart review. METHODS: A review was performed of patients who underwent functional endoscopic sinus surgery (FESS) for refractory chronic rhinosinusitis (CRS). Sino-Nasal Outcome Test-22 scores and cumulative prednisone dose (milligrams) requirements at 1, 3, and 6 months postoperatively were reviewed. A structured histopathology report of 11 variables was accessed to correlate histopathology with postoperative steroid requirements. RESULTS: One hundred one patients were reviewed including 42 CRS with nasal polyps and 59 CRS without nasal polyps patients. CRS patients with eosinophilia required greater cumulative steroids to control disease at 1-, 3-, and 6-month postoperative intervals (P < .026, P < .007, P < .013, respectively) compared to patients without eosinophilia. Patients with tissue eosinophil aggregates required the highest cumulative steroids at 1-, 3-, and 6-month postoperative intervals (P < .003, P < .001, P < .001, respectively). When removing patients with eosinophil aggregates from the eosinophilia group, no difference persisted between patients with eosinophilia and those without eosinophilia at all intervals (P = .664, P = .735, P = .800, respectively). No other histopathology variable correlated with postoperative steroid requirement. CONCLUSIONS: Tissue eosinophil aggregates appear to be the largest driving factor for increased prednisone requirements after sinus surgery to control mucosal disease than mere presence of eosinophils. This key finding may identify patients at high risk for failure after sinus surgery and guide more proactive postoperative management. LEVEL OF EVIDENCE: 4 Laryngoscope, 129:794-799, 2019.

Association of Perioperative Opioid-Sparing Multimodal Analgesia With Narcotic Use and Pain Control After Head and Neck Free Flap Reconstruction.

IMPORTANCE: An increase in narcotic prescription patterns has contributed to the current opioid epidemic in the United States. Opioid-sparing perioperative analgesia represents a means of mitigating the risk of opioid dependence while providing superior perioperative analgesia. OBJECTIVE: To assess whether multimodal analgesia (MMA) is associated with reduced narcotic use and improved pain control compared with traditional narcotic-based analgesics at discharge and in the immediate postoperative period after free flap reconstructive surgery. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study assessed a consecutive sample of 65 patients (28 MMA, 37 controls) undergoing free flap reconstruction of a through-and-through mucosal defect within the head and neck region at a tertiary academic referral center from June 1, 2017, to November 30, 2018. Patients and physicians were not blinded to the patients' analgesic regimen. Patients' clinical courses were followed up for 30 days postoperatively. INTERVENTIONS: Patients were administered a preoperative, intraoperative, and postoperative analgesia regimen consisting of scheduled and as-needed neuromodulating and anti-inflammatory medications, with narcotic medications reserved for refractory cases. Control patients were administered traditional narcotic-based analgesics as needed. MAIN OUTCOMES AND MEASURES: Narcotic doses administered during the perioperative period and at discharge were converted to morphine-equivalent doses (MEDs) for comparison. Postoperative Defense and Veterans Pain Rating Scale pain scores (ranging from 0 [no pain] to 10 [worst pain imaginable]) were collected for the first 72 hours postoperatively as a patient-reported means of analyzing effectiveness of analgesia. RESULTS: A total of 28 patients (mean [SD] age, 64.1 [12.3] years; 17 [61%] male) were included in the MMA group and 37 (mean [SD] age, 65.0 [11.0] years; 22 [59%] male) in the control group. The number of MEDs administered postoperatively was 10.0 (interquartile range [IQR], 2.7-23.1) in the MMA cohort and 89.6 (IQR, 60.0-104.5) in the control cohort (P < .001). Mean (SD) Defense and Veterans Pain Rating Scale pain scores postoperatively were 2.05 (1.41) in the MMA cohort and 3.66 (1.99) in the control cohort (P = .001). Median number of MEDs prescribed at discharge were 0 (IQR, 0-18.8) in the MMA cohort and 300.0 (IQR, 262.5-412.5) in the control cohort (P < .001). CONCLUSIONS AND RELEVANCE: The findings suggest that after free flap reconstruction, MMA is associated with reduced narcotic use at discharge and in the immediate postoperative period and with superior analgesia as measured by patient-reported pain scores. Patients receiving MMA achieved improved pain control, and the number of narcotic prescriptions in circulation were reduced. LEVEL OF EVIDENCE: 3.
