Cognition and saccadic eye movement performance are impaired in chronic rhinosinusitis

BACKGROUND

Patients with chronic rhinosinusitis (CRS) can experience cognitive dysfunction. The literature on this topic mostly reflects patient-reported measurements. Our goal was to assess cognitive function in patients with CRS using objective measures, including saccadic eye movements-a behavioral response reflecting cognitive and sensory information integration that is often compromised in conditions with impaired cognition.

METHODS

Participants (N = 24 with CRS, N = 23 non-CRS healthy controls) enrolled from rhinology clinic underwent sinonasal evaluation, quality of life assessment (Sino-nasal Outcome Test 22 [SNOT-22]), and cognitive assessment with the Neuro-QOL Cognitive Function-Short Form, the Montreal Cognitive Assessment (MoCA), and recording of eye movements using video-oculography.

RESULTS

Participants with CRS were more likely to report cognitive dysfunction (Neuro-QOL; 45.8% vs. 8.7%; p = 0.005) and demonstrate mild or greater cognitive impairment (MoCA; 41.7% vs. 8.7%; p = 0.005) than controls. Additionally, participants with CRS performed worse on the MoCA overall and within the executive functioning and memory domains (all p < 0.05) and on the anti-saccade (p = 0.014) and delay saccade (p = 0.044) eye movement tasks. Poorer performance on the MoCA (r = -0.422; p = 0.003) and the anti-saccade (r = -0.347; p = 0.017) and delay saccade (r = -0.419; p = 0.004) eye movement tasks correlated with worse CRS severity according to SNOT-22 scores.

CONCLUSION

This study is the first to utilize objective eye movement assessments in addition to researcher-administered cognitive testing in patients with CRS. These patients demonstrated a high prevalence of cognitive dysfunction, most notably within executive functioning and memory domains, with the degree of dysfunction correlating with the severity of CRS.

Sinus inflammation and chronic rhinosinusitis are associated with a diagnosis of new onset asthma in the following year

BACKGROUND

Chronic rhinosinusitis (CRS) and asthma commonly co-occur. No studies have leveraged large samples needed to formally address whether preexisting CRS is associated with new onset asthma over time.

METHODS

We evaluated whether prevalent CRS [identified in two ways: validated text algorithm applied to sinus computerized tomography (CT) scan or two diagnoses] was associated with new onset adult asthma in the following year. We used electronic health record data from Geisinger from 2008 to 2019. For each year we removed persons with any evidence of asthma through the end of the year, then identified those with new diagnosis of asthma in the following year. Complementary log-log regression was used to adjust for confounding variables (e.g., sociodemographic, contact with the health system, comorbidities), and hazard ratios (HRs) and 95% confidence intervals (CI) were calculated.

RESULTS

A total of 35,441 persons were diagnosed with new onset asthma and were compared to 890,956 persons who did not develop asthma. Persons with new onset asthma tended to be female (69.6%) and younger (mean [SD] age 45.9 [17.0] years). Both CRS definitions were associated (HR, 95% CI) with new onset asthma, with 2.21 (1.93, 2.54) and 1.48 (1.38, 1.59) for CRS based on sinus CT scan and two diagnoses, respectively. New onset asthma was uncommonly observed in persons with a history of sinus surgery.

CONCLUSION

Prevalent CRS identified with two complementary approaches was associated with a diagnosis of new onset asthma in the following year. The findings may have clinical implications for the prevention of asthma.

Orbital resection by intranasal technique (ORBIT): A new classification system for reporting endoscopically resectable primary benign orbital tumors

BACKGROUND

The Cavernous Hemangioma Exclusively Endonasal Resection (CHEER) staging system has become the gold standard for outcomes reporting in endoscopic orbital surgery for orbital cavernous hemangiomas (OCHs). A recent systematic review demonstrated similar outcomes between OCHs and other primary benign orbital tumors (PBOTs). Therefore, we hypothesized that a simplified and more comprehensive classification system could be developed to predict surgical outcomes of other PBOTs.

METHODS

Patient and tumor characteristics as well as surgical outcomes from 11 international centers were recorded. All tumors were retrospectively assigned an Orbital Resection by Intranasal Technique (ORBIT) class and stratified based on surgical approach as either exclusively endoscopic or combined (endoscopic and open). Outcomes based on approach were compared using chi-squared or Fisher's exact tests. The Cochrane-Armitage test for trend was used to analyze outcomes by class.

RESULTS

Findings from 110 PBOTs from 110 patients (age 49.0 ± 15.0 years, 51.9% female) were included in the analysis. Higher ORBIT class was associated with a lower likelihood of gross total resection (GTR). GTR was more likely to be achieved when an exclusively endoscopic approach was utilized (p < 0.05). Tumors resected using a combined approach tended to be larger, to present with diplopia, and to have an immediate postoperative cranial nerve palsy (p < 0.05).

CONCLUSION

Endoscopic treatment of PBOTs is an effective approach, with favorable short-term and long-term postoperative outcomes as well as low rate of adverse events. The ORBIT classification system is an anatomic-based framework that effectively facilitates high-quality outcomes reporting for all PBOTs.

Risk of new-onset and prevalent disease in chronic rhinosinusitis: A prospective cohort study

BACKGROUND

Chronic rhinosinusitis (CRS) is accompanied by burdensome comorbid conditions. Understanding the relative timing of the onset of these conditions could inform disease prevention, detection, and management.

OBJECTIVE

To evaluate the association between CRS and new-onset and prevalent asthma, noncystic fibrosis bronchiectasis (NCFBE), chronic obstructive pulmonary disease (COPD), gastroesophageal reflux disease (GERD), and obstructive sleep apnea (OSA).

METHODS

We conducted a prospective cohort study among primary care patients using a detailed medical and symptom questionnaire in 2014 and again in 2020. We used questionnaire and electronic health record (EHR) data to determine CRS status: CRSSE (moderate to severe symptoms with EHR evidence), CRSE (limited symptoms with EHR evidence), CRSS (moderate to severe symptoms without EHR evidence), CRSneg (limited symptoms and no EHR evidence; reference). We evaluated the association between CRS status and new-onset and prevalent disease using logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

There were 7847 and 4445 respondents to the 2014 and 2020 questionnaires, respectively. CRSSE (vs CRSneg ) was associated with increased odds of new-onset asthma (OR, 1.74 [CI, 1.09-2.77), NCFBE (OR, 1.87 [CI, 1.12-3.13]), COPD (OR, 1.73 [CI, 1.14-2.68]), GERD (OR, 1.95 [CI, 1.61-2.35]), and OSA (OR, 1.91 [CI, 1.39-2.62]). Similarly, increased odds were observed for associations with the prevalence of these conditions.

CONCLUSION

The findings from the study support further exploration of CRS as a target for the prevention and detection of asthma, NCFBE, COPD, GERD, and OSA.

Postmarketing Reporting of Paxlovid-Related Dysgeusia: A Real-World Pharmacovigilance Study

OBJECTIVE

A novel COVID-19 therapeutic, nirmatrelvir/ritonavir (Paxlovid), is commonly associated with reports of dysgeusia. The Food and Drug Administration Adverse Event Reporting System (FAERS) database was used to determine the real-world reporting of Paxlovid-associated dysgeusia (PAD), identify associated factors, and describe the relative reporting rates of dysgeusia for Paxlovid compared to other COVID-19 therapeutics (OCT), ritonavir alone, and other protease inhibitors (OPI).

STUDY DESIGN

Observational retrospective.

SETTING

Tertiary academic medical center.

METHODS

We collected patient and adverse event characteristics reported in the FAERS database between January 1968 and September 2022. Disproportionality analyses were used to compare the reporting of PAD to dysgeusia reported for OCT, ritonavir, and OPI.

RESULTS

345,229 adverse events were included in the present study. Dysgeusia was a frequently reported Paxlovid-associated adverse event (17.5%) and was associated with nonserious COVID-19 infection (reporting odds ratio [ROR] 1.4; 95% confidence interval [CI] 1.2, 1.7) and female sex (ROR = 1.7; 95% CI 1.6, 1.9). Paxlovid was more likely to be associated with the reporting of dysgeusia compared to OCT (ROR 305.4; 95% CI 164.1, 568.5), ritonavir (ROR 28.0; 95% CI 24.1, 32.7), and OPI (ROR 49.0; 95% CI 42.8, 56.1).

CONCLUSION

Dysgeusia is much more likely to be reported by patients receiving Paxlovid than those receiving OCT, ritonavir alone, or OPI. These findings suggest a potential mechanism of dysgeusia that causes distorted taste out of proportion to the background effects of COVID-19 infection and specific to nirmatrelvir. Future studies are needed to determine the underlying pathophysiology and long-term clinical implications for patients who report dysgeusia with Paxlovid.

Does reconstruction affect outcomes following exclusively endoscopic endonasal resection of benign orbital tumors: A systematic review with meta‐analysis

Objective

As exclusively endoscopic endonasal resection of benign orbital tumors has become more widespread, high‐quality outcomes data are lacking regarding the decision of when and how to reconstruct the medial orbital wall following resection. The goal of this study was to systematically review pertinent literature to assess clinical outcomes relative to orbital reconstruction practices.

Methods

Data Sources: PubMed, EMBASE, Web of Science. A systematic review of studies reporting exclusively endoscopic endonasal resections of benign orbital tumors was conducted. Articles not reporting orbital reconstruction details were excluded. Patient and tumor characteristics, operative details, and outcomes were recorded. Variables were compared using χ², Fisher's exact, and independent t tests.

Results

Of 60 patients included from 24 studies, 34 (56.7%) underwent orbital reconstruction following resection. The most common types of reconstruction were pedicled flaps (n = 15, 44.1%) and free mucosal grafts (n = 11, 32.4%). Rigid reconstruction was uncommon (n = 3, 8.8%). Performance of orbital reconstruction was associated with preoperative vision compromise (p < 0.01). The tendency to forego orbital reconstruction was associated with preoperative proptosis (p < 0.001), larger tumor size (p = 0.001), and operative exposure of orbital fat (p < 0.001) and extraocular muscle (p = 0.035). There were no statistically significant differences between the reconstruction and nonreconstruction groups in terms of short‐ or long‐term outcomes when considering all patients. In patients with intraconal tumors, however, there was a higher rate of short‐term postoperative diplopia when reconstruction was foregone (p = 0.041). This potential benefit of reconstruction did not persist: At an average of two years postoperatively, all patients for whom reconstruction was foregone either had improved or unchanged diplopia.

Conclusion

Most outcomes assessed did not appear affected by orbital reconstruction status. This general equivalence may suggest that orbital reconstruction is not a necessity in these cases or that the decision to reconstruct was well‐selected by surgeons in the reported cases included in this systematic review.

Question: Does orbital reconstruction affect outcomes following exclusively endoscopic endonasal resection of benign orbital tumors?

Findings: In this systematic review and meta‐analysis of 60 patients included from 24 studies, there were no statistically significant differences between the reconstruction (n = 34, 56.7%) and non‐reconstruction groups in terms of short‐ or long‐term outcomes when considering all patients. In patients with intraconal tumors, however, there was a higher rate of short‐term (<2 years) post‐operative diplopia when reconstruction was foregone (p = 0.041).

Meaning: Most outcomes assessed did not appear affected by orbital reconstruction status. This general equivalence may suggest that orbital reconstruction is not a necessity in these cases or that the decision to reconstruct was well‐selected by surgeons in the reported cases included in this systematic review.

Reflecting on the COVID-19 Surgical Literature Surge: A Scoping Review of Pandemic Otolaryngology Publications

OBJECTIVE

To assess the high-volume 2020 COVID-19-related surgical literature, with special attention to otolaryngology articles in regard to content, level of evidence, citations, and public attention.

STUDY DESIGN

A scoping literature review was performed with PubMed and Web of Science, including articles pertaining to COVID-19 and surgical specialties (March 20-May 19, 2020) or otolaryngologic subspecialties (March 20-December 31, 2020).

SETTING

Scoping literature review.

METHODS

Otolaryngology-specific COVID-19-related articles were reviewed for publication date, county of origin, subspecialty, content, level of evidence, and Altmetric Attention Score (a weighted approximation of online attention received). Data were analyzed with Pearson correlation coefficients, analysis of variance, independent t tests, and univariable and logistic regressions.

RESULTS

This review included 773 early COVID-19 surgical articles and 907 otolaryngology-specific COVID-19-related articles from 2020. Otolaryngology was the most represented surgical specialty within the early COVID-19-related surgical literature (30.4%). The otolaryngology-specific COVID-19 surgical literature responsively reflects the unique concerns within each otolaryngologic subspecialty. Although this literature was largely based on expert opinion (64.5%), articles with stronger levels of evidence received significantly more citations (on Web of Science and Google Scholar, P < .001 for both) and public attention (according to Altmetric Attention Scores, P < .001).

CONCLUSION

Despite concerns of a surge in underrefereed publications during the COVID-19 pandemic, our review of the surgical literature offers some degree of reassurance. Specifically, the COVID-19 otolaryngology literature responsively reflects the unique concerns and needs of the field, and more scholarly citations and greater online attention have been given to articles offering stronger levels of scientific evidence.

Socioeconomic Factors Affect Presentation Stage and Survival in Sinonasal Squamous Cell Carcinoma

OBJECTIVES

Socioeconomic factors affect oncologic outcome in sinonasal squamous cell carcinoma (SNSCC). However, the relationship between these factors and stage at presentation (SAP)-a critical, early point in the care cycle-is not known. This study sought to determine the role of race/ethnicity, treatment facility type, insurance status/carrier, and other socioeconomic factors in SAP and survival among patients with advanced SNSCC.

STUDY DESIGN

Retrospective cohort study.

METHODS

Using the National Cancer Database, 6,155 patients with SNSCC were identified and divided into those with "early" (Stage I or II; 2,212 (35.9%)) versus "advanced" (Stage III or IV; 3,943 (64.1%)) disease. Associations between sociodemographic and socioeconomic factors on SAP and survival were analyzed using multivariable logistic regression and Cox proportional hazard models.

RESULTS

Black (odds ratio [OR]: 2.18, CI: 1.74-2.76), Asian and Pacific Islander (API) (OR: 2.37, CI: 1.43-4.14), and Medicaid or uninsured (OR: 2.04, CI: 1.66-2.53) patients were more likely to present with advanced disease. Among patients with advanced disease, API patients demonstrated the highest 10-year survival rate (30.2%), and Black patients had the lowest 2-, 5-, and 10-year survival rates (47.7%, 31.9% and 19.2%, respectively). Older age (HR:1.03, CI:1.03-1.04), Black race (HR:1.39, CI:1.21-1.59), Medicaid or uninsured status (HR:1.48, CI:1.27-1.71), and treatment at a community hospital (HR:1.25, CI:1.14-1.37) were associated with poorer overall survival among patients with advanced disease.

CONCLUSIONS

Factors including race/ethnicity, treatment facility type, insurance status/carrier, and other socioeconomic factors influence SAP and survival in SNSCC. An improved understanding of how these factors relate to outcomes may elucidate opportunities to address gaps in education and access to care in vulnerable populations.

Prolapsed Nasal Polyp Causing Acute Airway Obstruction: An Exceptional Presentation

Although nasal polyposis is a common clinical entity, there is limited literature describing the rare presentation of sudden prolapse of a massive nasal polyp resulting in an airway emergency in an adult. We present the first case report to our knowledge of a patient without any preceding sinonasal symptoms or history of anticoagulation who experienced acute upper airway obstruction due to sudden hemorrhage and prolapse of a large nasal polyp. Based on our experience treating this patient, we discuss special considerations in all phases of care to ensure safe and effective management of such an exceptional clinical scenario.

Exclusively endoscopic endonasal resection of benign orbital tumors: a systematic review and meta-analysis

BACKGROUND

The Cavernous Hemangioma Exclusively Endonasal Resection (CHEER) classification system was developed to standardize prospective outcome analysis following orbital cavernous hemangioma (OCH) resection. The goal of this study was to retroactively apply the CHEER system to all prior existing reports of endoscopic resection of primary benign orbital tumors (BOTs) to: (1) compare patient presentations, perioperative characteristics, and outcomes between OCH and other BOTs; and (2) determine whether the CHEER categorization regime could be expanded to other BOTs.

METHODS

A systematic review of studies reporting exclusively endoscopic resections of OCH and other BOTs (eg, solitary fibrous tumor, schwannoma, and meningioma) was performed. Patient, tumor characteristics, and operative outcomes were recorded. All tumors with adequate reporting were retrospectively assigned a CHEER stage. Outcomes were compared using chi-square or Fisher's exact tests.

RESULTS

Ninety-three studies met inclusion criteria, and sufficient data were available in 36 studies, comprising 105 tumors (n = 87 OCHs; n = 18 other BOTs). Baseline patient and tumor characteristics, as well as intraoperative and short-term postoperative outcomes were not significantly different between OCHs and other BOTs. Long-term outcomes (eg, visual deficits, diplopia, eye position, and recurrence) also did not differ when controlling for CHEER stage.

CONCLUSION

This review represents the largest collection of outcomes data following exclusively endoscopic endonasal resection of BOTs. Short-term and long-term outcomes appear similar between OCHs and other BOTs. These results suggest that exclusively endoscopic resection of orbital tumors may be effective in a range of benign pathologies. Furthermore, these results support a broader application of the CHEER system to other benign primary orbital tumors.

Prophylactic antibiotics after endoscopic sinus surgery for chronic rhinosinusitis: a randomized, double-blind, placebo-controlled noninferiority clinical trial

BACKGROUND

Surgeons commonly prescribe prophylactic antibiotics after endoscopic sinus surgery (ESS), yet minimal data exist to support this practice. In this study we aimed to assess the impact of post-ESS antibiotics on infection, quality of life (QOL), and endoscopic scores.

METHODS

This was a randomized, double-blind, placebo-controlled, noninferiority trial comparing amoxicillin-clavulanate vs placebo after ESS (NCT01919411, ClinicalTrials.gov). Adults (N = 77) with chronic rhinosinusitis (CRS) refractory to appropriate medical therapy who underwent ESS were randomized to antibiotics (N = 37) or placebo (N = 40) and followed clinically (mean ± standard deviation: 1.3 ± 0.3 and 8.8 ± 3.9 weeks postoperatively). At baseline and follow-up, QOL was measured with 22-item Sino-Nasal Outcome Test questionnaires and Lund-Kennedy endoscopic scores were evaluated. Outcomes were analyzed with repeated-measures analysis of variance and analysis of covariance and z tests for proportions.

RESULTS

Placebo was noninferior to antibiotic prophylaxis with regard to postoperative SNOT-22 scores (β = 0.18, 2-tailed p < 0.05). There were no significant differences between the antibiotic and placebo groups in LK score trajectories over time (p = 0.63) or in postoperative infection rates (2.6% vs 2.4%, respectively; p = 0.96). The rate of diarrhea was significantly higher in the antibiotic group (24.3% vs 2.5%; relative risk = 10.8; p = 0.02).

CONCLUSION

Although statistically underpowered, the results suggest placebo was noninferior to prophylactic antibiotics after ESS for CRS regarding postoperative sinonasal-specific QOL. There were no significant differences in postoperative endoscopic scores or rates of infection, but the rate of diarrhea was significantly higher in the antibiotic group. These findings add to the growing evidence that routine use of prophylactic postoperative antibiotics does not improve outcomes post-ESS and significantly increases the rate of diarrhea.

Radioanatomic Characteristics of the Posteromedial Intraconal Space: Implications for Endoscopic Resection of Orbital Lesions

BACKGROUND AND PURPOSE

Imaging is essential in the diagnostic work-up of patients with orbital lesions. The position of an orbital lesion relative to the inferomedial muscular trunk of the ophthalmic artery determines endoscopic resectability, anticipated technical difficulty, and patient morbidity. Although the inferomedial muscular trunk is not readily identifiable on preoperative imaging, we hypothesize that it is spatially approximate to the location where the ophthalmic artery crosses the optic nerve. Our aim was to determine whether the ophthalmic artery-optic nerve crosspoint anatomically approximates the inferomedial muscular trunk in a cadaver study and can be appreciated on imaging of known posteromedial orbital lesions.

MATERIALS AND METHODS

Dissection was performed on 17 fresh-frozen cadaver orbits to assess the relationship between the inferomedial muscular trunk and ophthalmic artery-optic nerve crosspoint. Retrospective review of imaging in 9 patients with posteromedial orbital lesions assessed posteromedial orbital compartment characteristics and the ability to locate the ophthalmic artery-optic nerve crosspoint.

RESULTS

In our cadaver study, the mean distance between the ophthalmic artery-optic nerve crosspoint and the inferomedial muscular trunk was 1.21 ± 0.64 mm. Retrospectively, the ophthalmic artery-optic nerve crosspoint was identifiable in 9/9 patients, whereas the inferomedial muscular trunk was not identifiable in any patient. Total or partial effacement of the posteromedial intraconal fat triangle was observed in 9/9 patients.

CONCLUSIONS

This study of neurovascular relationships within the posteromedial orbit demonstrates that the ophthalmic artery-optic nerve crosspoint closely approximates the inferomedial muscular trunk and can be seen in patients with posteromedial orbital lesions. Posteromedial intraconal fat effacement may help to localize these lesions. These findings may facilitate multidisciplinary communication and help predict lesion resectability and patient outcomes.

Infection After Endoscopic Dacryocystorhinostomy: Incidence and Implications

BACKGROUND

Endoscopic dacryocystorhinostomy (EN-DCR) is an increasingly common procedure performed by otolaryngologists. While EN-DCR has a high rate of success at relieving blockage of the lacrimal system, little is known regarding associated postoperative infection (POI) rates and risk factors.

OBJECTIVE

The purpose of this study was to identify factors associated with the occurrence of postoperative orbital and rhinologic infection in a large cohort of patients undergoing EN-DCR.

METHODS

A retrospective review of 582 patients who underwent EN-DCR was performed. All patients received antibiotic prophylaxis as a single intraoperative intravenous administration and a ten-day postoperative oral course. Clinical and demographic information was reviewed, including the occurrence of acute orbital or rhinologic infection within 30 days of surgery. Multivariable analysis was performed to identify risk factors associated with POI.

RESULTS

Fifteen of 582 patients (2.6%) developed POI following EN-DCR. The most common POI was acute rhinosinusitis (10/15, 66.7%), followed by acute dacryocystitis (2/15, 13.3%), preseptal cellulitis (2/15,13.3%), and acute bacterial conjunctivitis (1/15, 6.7%). The majority of patients (464/582, 79.7%) underwent concurrent endoscopic sinus surgery (ESS). In most cases (302/464, 65.1%), ESS was performed to address comorbid rhinosinusitis, whereas 7.8% (36/464) of patients underwent surgery to enhance surgical access to the lacrimal sac. Patients who underwent concurrent ESS were less likely to develop POI (OR: 0.17, CI: 0.04-0.80, p < 0.05). Evidence of mucopurulence at surgery increased the likelihood of POI (OR: 6.24, CI: 1.51-25.84, p < 0.05).

CONCLUSION

Mucopurulence at the time of surgery significantly increased the risk of POI, whereas concurrent ESS, performed most commonly to address comorbid rhinosinusitis, significantly decreased the risk of POI. Awareness of risk factors for POI and appropriate surgical management of concurrent rhinosinusitis can lead to reduced infectious complications after EN-DCR.

Endoscopic Transoral Image-Guided Retrieval of Infratemporal Fossa Foreign Bodies

Removal of foreign bodies from the infratemporal fossa is surgically challenging and fraught with risks. This report describes our experience with a minimally invasive transoral technique, utilizing endoscopic and image guidance technology, for retrieval of infratemporal fossa foreign bodies in 6 patients. The technique was successfully applied in all cases with identification and retrieval of the foreign bodies, which included 4 hypodermic needles broken off during dental injections, a cottonoid surgical sponge lost during a facial fracture repair, and a maxillary molar displaced during attempted extraction. Complications were limited to transient postoperative lingual and inferior alveolar nerve sensory deficits in 1 patient.

Prognostic Impact of Adverse Pathologic Features in Sinonasal Squamous Cell Carcinoma

Objective  This study aimed to describe the impact of adverse clinical and pathologic features in sinonasal squamous cell carcinoma (SCC). Design  This study is designed with retrospective chart review. Setting  The present study is conducted at a tertiary care institution. Participants  All patients treated surgically for sinonasal SCC at our tertiary care institution between January 2006 and December 2013. Main Outcome Measures  Overall survival (OS) and disease free survival (DFS) are the final measurement of this study. Results  Forty-eight patients were identified. Mean age at surgery was 65.8 years, and mean follow-up time was 40.7 months. Eighteen patients (38%) had T1-T3 disease, while 30 patients (63%) had T4 disease. Seven patients (8.3%) had nodal disease at presentation. At 2, 5, and 10 years, OS was 71, 54, and 48%, respectively, while DFS was 64, 51, and 45%, respectively. Twelve patients (25%) experienced local recurrences with mean time to recurrence of 15.3 months. Twenty-five patients (52%) had positive margins, 24 (50%) had high-grade tumors, 18 (38%) had perineural invasion (PNI), and 15 (31%) had lymphovascular invasion (LVI). In the univariate analysis, T4 disease (risk ratio [RR] = 2.7) and high grade (RR = 2.4) had a significant association with DFS. In the multivariate analysis, high grade (RR = 4.0 and 4.5) and LVI (RR = 4.1 and 4.7) had a significant association with OS and DFS. Conclusion  Our single-institution experience of 48 patients suggests that high grade and LVI are independently associated with survival outcomes in sinonasal SCC, while PNI and microscopically positive margins do not have a significant impact.

Human Papillomavirus Related Multiphenotypic Sinonasal Carcinoma: Report of a Case with Early and Progressive Metastatic Disease

Introduction  Human papillomavirus (HPV) related multiphenotypic sinonasal carcinoma (HMSC) is a newly described entity. The prognosis of this neoplasm is not well understood, but cases often demonstrate high-grade features and paradoxically indolent behavior.

Case Report  We present the case of a 65-year-old man referred with unilateral nasal congestion and epistaxis. Nasal endoscopy and imaging revealed an expansile mass filling the left nasal cavity. The patient underwent endoscopic-assisted medial maxillectomy, with complete resection and negative margins. Pathology revealed a basaloid tumor consisting of solid nests with multiple foci of cribriform architecture, with positivity for high-risk HPV, thus supporting the diagnosis of HMSC. Postoperatively, the patient received 66.6-Gy adjuvant three-dimensional proton therapy. Twenty-three months after surgical resection, he developed enlarging pulmonary nodules with biopsy features consistent with the primary sinonasal tumor. He was treated with three cycles of chemotherapy and eight cycles of immunotherapy, progressing on both therapies. He remains on palliative chemotherapy.

Conclusion  Here, we present a case of HMSC with early and progressive distant metastasis. We aim to add to an understanding of the behavior of this entity. Although this neoplasm may typically be indolent, further classification of high-risk features is necessary to identify rare aggressive cases.

Periostin and Inflammatory Disease: Implications for Chronic Rhinosinusitis

OBJECTIVE

To provide a comprehensive overview of the emerging role of periostin, an extracellular matrix protein, as a key component in the development, diagnosis, and treatment of patients with chronic rhinosinusitis.

DATA SOURCES

Medline database.

REVIEW METHODS

A state of the art review was performed targeting English-language studies investigating the role of periostin in cardiopulmonary, neoplastic, and inflammatory diseases, with emphasis on recent advances in the study of periostin in chronic rhinosinusitis.

CONCLUSIONS

Periostin has emerged as a novel biomarker and therapeutic target for numerous human pathologies, including cardiac, pulmonary, and neoplastic disease. The upregulation of periostin in chronic rhinosinusitis suggests the potential for similar roles among patients with sinonasal disease.

IMPLICATIONS FOR PRACTICE

Chronic rhinosinusitis is a widespread disease with major clinical and societal impact. A critical limitation in the current treatment of patients with chronic rhinosinusitis is the absence of clinically relevant biomarkers to guide diagnosis and treatment selection. A review of the literature supports a likely role of periostin as a biomarker of chronic rhinosinusitis, as well as a novel therapeutic target in the future treatment of patients with sinonasal disease.

Opioid prescription patterns and use among patients undergoing endoscopic sinus surgery

OBJECTIVES/HYPOTHESIS

Opioid-related deaths in the United States have increased 200% since 2000, in part due to prescription diversion from patients who had a surgical procedure. The purpose of this study was to characterize provider prescription patterns and assess patient-reported opioid use after endoscopic sinus surgery (ESS).

STUDY DESIGN

Retrospective chart review.

METHODS

Patients who underwent ESS between May 2017 and May 2018 were included. Opioid prescription, operative details, and postoperative opioid use data were extracted. The Massachusetts Prescription Awareness Tool (MassPAT) was queried to determine if patients filled their prescription.

RESULTS

One hundred fifty-five patients were included. Nearly all patients received an opioid prescription (94.8%). An average of 15.6 tablets was prescribed per patient. Among 116 patients with MassPAT data, 91.4% filled their prescription. Among 67 patients who reported the number of tablets they had used at the time of first follow-up appointment, 73.1% reported taking no opioids. Mean number of tablets prescribed was significantly greater among patients who underwent primary versus revision surgery (16.5 vs. 13.5, P = .0111) and those who had splints placed (21.5 vs. 15.1, P = .0037). Predictors of opioid use included concurrent turbinate reduction (58.3% vs. 14.3%, P < .0001) and concurrent septoplasty (45.5% vs. 21.6%, P = .039).

CONCLUSIONS

Nearly all patients who underwent ESS were prescribed an opioid, and nearly all patients filled their prescription. However, the vast majority of patients did not require any opioid medication for postoperative pain control. As the opioid epidemic continues to persist, these findings have immediate relevance to current prescribing patterns and pain management practices.

Social media utilization in the cochlear implant community

BACKGROUND

More than 200,000 individuals worldwide have received a cochlear implant (CI). Social media Websites may provide a paramedical community for those who possess or are interested in a CI. The utilization patterns of social media by the CI community, however, have not been thoroughly investigated.

PURPOSE

The purpose of this study was to investigate participation of the CI community in social media Websites.

RESEARCH DESIGN

We conducted a systematic survey of online CI-related social media sources. Using standard search engines, the search terms cochlear implant, auditory implant, forum, and blog identified relevant social media platforms and Websites. Social media participation was quantified by indices of membership and posts.

STUDY SAMPLE

Social media sources included Facebook, Twitter, YouTube, blogs, and online forums. Each source was assigned one of six functional categories based on its description.

INTERVENTION

No intervention was performed.

DATA COLLECTION AND ANALYSIS

We conducted all online searches in February 2014. Total counts of each CI-related social media source were summed, and descriptive statistics were calculated.

RESULTS

More than 350 sources were identified, including 60 Facebook groups, 36 Facebook pages, 48 Twitter accounts, 121 YouTube videos, 13 forums, and 95 blogs. The most active online communities were Twitter accounts, which totaled 35,577 members, and Facebook groups, which totaled 17,971 members. CI users participated in Facebook groups primarily for general information/support (68%). Online forums were the next most active online communities by membership. The largest forum contained approximately 9,500 topics with roughly 127,000 posts. CI users primarily shared personal stories through blogs (92%), Twitter (71%), and YouTube (62%).

CONCLUSIONS

The CI community engages in the use of a wide range of online social media sources. The CI community uses social media for support, advocacy, rehabilitation information, research endeavors, and sharing of personal experiences. Future studies are needed to investigate how social media Websites may be harnessed to improve patient-provider relationships and potentially used to augment patient education.

Periostin as a Biomarker for Nasal Polyps in Chronic Rhinosinusitis

Objective Periostin is an extracellular matrix protein that is elevated in the sinonasal tissues of patients with chronic rhinosinusitis (CRS). The purpose of this study was to determine whether serum periostin could serve as a molecular biomarker of nasal polyp burden in sinonasal disease. Study Design Prospective cohort study. Setting Academic medical center. Subjects and Methods Serum periostin levels were measured by ELISA on blood samples collected from patients undergoing sinus surgery for CRS (n = 71), further stratified by phenotype as defined by nasal polyps and asthma. Results were compared with assays performed on control subjects (n = 62). Results Mean serum periostin levels were markedly elevated in patients with CRS versus controls (66.1 ng/mL [95% CI, 51.6-80.6] vs 38.7 ng/mL [95% CI, 34.4-42.9], respectively, P = .004). In addition, mean periostin levels were significantly higher in CRS patients with nasal polyps as compared with those without polyps (94.8 ng/mL [95% CI, 67.3-122.4] vs 41.1 ng/mL [95% CI, 35.2-47.0], respectively, P < .001). Periostin levels did not correlate with sex ( P = .473), smoking history ( P = .748), aspirin-exacerbated respiratory disease status ( P = .136), oral steroid use within 1 month of surgery ( P = .281), use of topical steroid nasal spray ( P = .864), or number of prior sinus operations ( P = .973). Conclusion Serum periostin appears to be a novel molecular biomarker for the presence of nasal polyps and may serve as an indicator of CRS endotypes.

The value of frontal sinusotomy for chronic rhinosinusitis with nasal polyps-A cost utility analysis

OBJECTIVES/HYPOTHESIS

The number of surgical procedures performed for frontal sinusitis and the associated costs have increased dramatically over the past decade. The purpose of this study was to evaluate the cost-effectiveness of endoscopic frontal sinusotomy (EFS) in patients with chronic rhinosinusitis with nasal polyposis (CRSwNP).

STUDY DESIGN

Cohort-style Markov decision-tree economic model with a 36-year time horizon.

METHODS

Matched cohorts of CRSwNP patients who underwent endoscopic sinus surgery (ESS) with (n = 139) and without (n = 49) EFS were compared to each other and to patients (n = 139) from the Medical Expenditures Survey Panel database who underwent medical management for chronic rhinosinusitis. Multi-year health utility values were calculated from responses to the EuroQol 5-Dimension instrument. The primary outcome measure was the incremental cost-effectiveness ratio (ICER).

RESULTS

Decision analysis showed that ESS without EFS proved more cost-effective than ESS with EFS or medical management. ESS without EFS compared to medical management yielded an ICER of $9,004/quality-adjusted life year (QALY). ESS with EFS compared to ESS without EFS yielded an ICER of $62,310/QALY. At a willingness-to-pay (WTP) threshold of $50,000/QALY, ESS without EFS was more cost-effective than ESS with EFS with 52.1% certainty. These results were robust to one-way analysis and probabilistic sensitivity analysis.

CONCLUSIONS

ESS remains a cost-effective intervention compared to medical therapy alone for patients with CRSwNP. In this study, the addition of frontal sinusotomy during ESS for patients with CRSwNP was not found to be cost-effective at a WTP threshold of $50,000/QALY, but may be cost effective at a higher threshold of $100,000/QALY.

Resident responses to after-hours otolaryngology patient phone calls: An overlooked aspect of residency training?

OBJECTIVES/HYPOTHESIS

Otolaryngology residents are often responsible for triaging after-hours patient calls. However, residents receive little training on this topic. Data are limited on the clinical content, reporting, and management of otolaryngology patient calls. This study aimed to characterize the patient concerns residents handle by phone and their subsequent management and reporting.

STUDY DESIGN

Retrospective review.

METHODS

Five hundred consecutive after-hours patient calls in a tertiary pediatric hospital were reviewed. Data collected included patient and caller demographics, clinical concerns, surgical history, recommendations, and subsequent emergency department (ED) visits.

RESULTS

On average, 3.7 calls occurred per shift, 2.8 on weekday and 5.9 on weekend shifts. Mean patient age was 6.6 years. Mothers (71%) called most frequently. The majority of calls were postoperative (64.2%). Of postoperative calls, most occurred within 3 days of surgery (52.3%). Most calls were for surgical site bleeding (19.9%). Residents recommended ED evaluation for 17.2% of calls, of which 20.9% returned to the primary institution ED. ED evaluation was recommended more frequently for postoperative patients (P = .040), particularly following adenotonsillectomy (51.2%) or surgical site bleeding (18.6%). With respect to documentation, 32.8% of medical record numbers were absent, 11.8% had name errors, and 2.2% of patients could not be identified.

CONCLUSIONS

This is the first study to analyze the management and reporting of patient calls by otolaryngology residents. A wide array of clinical concerns are triaged by phone conversations. The study has implications for both resident and patient education.

Plunging ranula with prestyloid parapharyngeal space, masticator space, and parotid gland extension

Plunging ranula with prestyloid parapharyngeal space, masticator space, and parotid gland extension.

INTRODUCTION

Ranulas develop from mucous extravasation secondary to sublingual gland duct obstruction or trauma. Plunging ranula usually dive into the submandibular space.

METHODS

This is the first reported case of a plunging ranula with direct extension to the prestyloid parapharyngeal space, masticator space, and parotid gland with avoidance of the submandibular space.

RESULTS

The patient presented with a tender parotid mass, of which the differential is broad, including parotitis, parotid malignancy, metastatic malignancy, lymphoma, as well as other infectious etiologies. When an intraoral component is not identified, other differential considerations would be thyroglossal duct cyst, branchial cleft cyst, parathyroid cyst, cervical thymic cyst, dermoid cyst, cystic hygroma, or benign teratoma.

CONCLUSION

The case is unique due to ranula extension into multiple spaces. For optimal treatment, the sublingual gland along with its tract and contents needs to completely removed.

Systematic review of outcomes following observational and operative endoscopic middle ear surgery

OBJECTIVES

Middle ear surgery increasingly employs endoscopes as an adjunct to or replacement for the operative microscope. We provide a systematic review of endoscope applications in middle ear surgery with an emphasis on outcomes, including the need for conversion to microscope, audiometric findings, length of follow-up, as well as disease-specific outcomes.

DATA SOURCES

PubMed, Embase, and Cochrane CENTRAL database.

METHODS

A literature review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis recommendations. Articles were categorized based on study design, indication, and use of an endoscope either as an adjunct to or as a replacement for a microscope. Qualitative and descriptive analyses of studies and outcomes data were performed.

RESULTS

One-hundred three articles met inclusion and exclusion criteria. Of the identified articles, 38 provided outcomes data. The majority of these studies were moderate quality, retrospective, case-series reports. The indications for use of the endoscope were broad, with the most common being resection of cholesteatoma. In cholesteatoma surgery, endoscope approaches routinely identified residual cholesteatoma in primary and second-look cases. Other outcomes, including robust audiometric data, operating room times, wound healing, and quality of life surveys were not well described.

CONCLUSIONS

Endoscopes have consistently been used as an adjunct to the microscope to improve visualization of the tympanic cavity. Recent reports utilize the endoscope exclusively during surgical dissection; however, data comparing patient outcomes following the use of an endoscope to a microscope are lacking. Areas in need of additional research are highlighted.

Direct visualization of the murine dorsal cochlear nucleus for optogenetic stimulation of the auditory pathway

Investigation into the use of virus-mediated gene transfer to arrest or reverse hearing loss has largely been relegated to the peripheral auditory system. Few studies have examined gene transfer to the central auditory system. The dorsal cochlear nucleus (DCN) of the brainstem, which contains second order neurons of the auditory pathway, is a potential site for gene transfer. In this protocol, a technique for direct and maximal exposure of the murine DCN via a posterior fossa approach is demonstrated. This approach allows for either acute or survival surgery. Following direct visualization of the DCN, a host of experiments are possible, including injection of opsins into the cochlear nucleus and subsequent stimulation by an optical fiber coupled to a blue light laser. Other neurophysiology experiments, such as electrical stimulation and neural injector tracings are also feasible. The level of visualization and the duration of stimulation achievable make this approach applicable to a wide range of experiments.

Incidence and survival patterns of sinonasal undifferentiated carcinoma in the United States

Objective To determine trends in sinonasal undifferentiated carcinoma (SNUC) survival patterns in the United States. Design Retrospective review of national database. Participants All cases of SNUC in the National Cancer Institute's Surveillance Epidemiology and End Results program from 1973 to 2010 were examined. Main Outcome Measures Age-adjusted incidence and survival rates were calculated and stratified by demographic information and treatment modality. Cohort analysis was performed to analyze survival patterns over time. Results A total of 318 SNUC cases were identified. Age-adjusted incidence rate (IR) was 0.02 per 100,000. Incidence was greater in males (IR: 0.03) than females (IR: 0.01; p = 0.03). Overall 5- and 10-year relative survival rate was 34.9% and 31.3%, respectively. Overall median survival was 22.1 months. Median survival following surgery combined with radiation was 41.9 months. Five-year relative survival rate following surgery, radiation, or surgery combined with radiation was 38.7%, 36.0%, and 39.1%, respectively. Median survival from 1973-1986 and 1987-2010 was 14.5 and 23.5 months, respectively. Conclusions This study provides new data regarding survival patterns of SNUC in the United States, confirming survival benefit with surgery and radiation as well as identifying a trend toward improved survival in recent decades.

Histologic Analysis of Chronos in an Optogenetic-Based Auditory Brainstem Implant Model

Objectives:

Optogenetics affords the potential for improved spatial resolution compared with electric stimulation in future auditory neuroprostheses. No histologic studies have yet examined the virally-mediated gene transfer of Chronos, a new opsin, to the murine cochlear nucleus (CN). Herein, we aim to (1) identify CN regions and neurons receptive to gene transfer of Chronos and (2) describe the morphology of putative cell types that express Chronos.

Methods:

CBA/CaJ mice underwent CN-targeted injection of Chronos. The Chronos construct consisted of an adeno-associated viral vector (AA2/8), CAG promoter, and a fluorescent marker. Following a 4-week incubation period, mice were sacrificed and intravascularly fixed with paraformaldehyde, and brains were extracted, sucrose cryoprotected, and cryostatically sectioned. Sections of 35-µm thickness were co-labeled with neuron-specific markers microtubule associated protein-2 and anti-tubulin, beta III isoform and DAPI-fluoromounted. Sections of 60-µm thickness were DAPI-fluoromounted, and confocal microscopy revealed cellular morphologies.

Results:

Opsin-linked fluorescence demonstrates Chronos expression throughout the dorsal CN with contiguous extension routinely into the ventral CN and variably into the auditory nerve and inferior cerebellar peduncle. Chronos localizes to neuronal-specific and nonneuronal populations. Confocal microscopy suggests involvement of a wide array of CN cell types, including morphologies consistent with pyramidal cells and giant cells.

Conclusions:

Our histologic analyses confirm widespread infection of multiple neuronal populations throughout the CN. This work sets the stage for correlation with ongoing neurophysiology experiments. Future work with CN-specific promoters to target neuronal subpopulations may further improve clinical potential for an optogenetics-based auditory neuroprosthesis.

Temperature Changes Associated with Middle Ear Endoscopy in a Human Temporal Bone Model

Objectives:

Endoscopic ear surgery is rapidly gaining popularity as a minimally invasive approach to address chronic ear disease. However, little is known about the potentially damaging temperature increases associated with endoscopy in the middle ear. Specifically, neither temperature change nor heat distribution associated with the endoscope has been quantified. In this study, we aim to measure temperature changes throughout the middle ear during rigid endoscopy in a human temporal bone model.

Methods:

Fresh human temporal bones were maintained at physiologic temperature during middle ear endoscopy with a 3-mm 0° Hopkins rod. Temperature changes were measured as a function of the distance between the endoscope tip and the round window membrane. Thermal gradient was determined by infrared imaging. Control studies conducted at room temperature were also performed.

Results:

An endoscope with a xenon or light-emitting diode light source on maximal power induced a rapid temperature elevation up to 46°C within 0.5-1 mm of the tip of the endoscope within 30-124 seconds. Elevated temperatures occurred at distances up to 8mm from the endoscope tip. Temperatures rapidly returned to baseline within 20-88 seconds after turning off the light source.

Conclusions:

Our findings have direct implications for endoscopic ear surgery and affirm the importance of avoiding excessive temperature elevation. We recommend employing submaximal light intensity and repositioning the endoscope frequently to provide rapid cooling. Ongoing studies use an animal model to explore the in vivo effects of prolonged middle ear endoscopy and evaluate for potential threshold shifts in auditory brainstem responses.

Current Landscape of Social Media and Blogosphere in the Cochlear Implant Community

Objectives:

Over 200,000 individuals worldwide have received a cochlear implant (CI). Social media websites may provide a paramedical community for CI users, although their utilization patterns have not been thoroughly investigated. Herein, we aim to (1) analyze how CI users exchange information online and (2) quantify and characterize participation in social media.

Methods:

Social media sources included Facebook, Twitter, YouTube, blogs, and online forums. Each source was assigned 1 of 6 functional categories based on its description. Using standard search engines, such as Google, we used the search terms cochlear implant, auditory implant, forum, and blog to identify relevant blogs and online forums. Website participation was quantified.

Results:

Over 350 sources were identified, including 122 YouTube videos, 111 blogs and forums, 57 Facebook groups, 32 Facebook pages, and 50 Twitter accounts. The most active online communities were Facebook groups, which totaled 17,971 members. CI users participated in Facebook groups primarily for general information/support (68%). Online forums were the next most active online communities by membership. The largest forum had ~9500 topics with ~127,000 posts. CI users primarily shared personal stories through blogs (92%), Twitter (71%), and YouTube (62%).

Conclusions:

This is the first known comprehensive review of utilization patterns of social media in the CI community. CI users engage in a wide range of online platforms predominately to provide general information and share personal stories. Analyses of how CI users participate in social media may enable clinicians to identify key concerns of this specialized patient population.

Evidence for a hyporesponsive limbic-hypothalamic-pituitary-adrenal axis following early-life repetitive hypoglycemia in adult male rats

The developing limbic-hypothalamic-pituitary-adrenal (LHPA) axis is highly vulnerable to programming by early-life environmental factors, including exposure to synthetic glucocorticoids and nutrient deficiencies. Early-life repetitive hypoglycemia (RHG) is a common complication of insulin therapy for type-1 diabetes that may have long-term consequences in adulthood. Recent observations in a rat model of early RHG suggest persistent changes in LHPA axis function, including changes in relevant hormones and affective behaviors, which support a hyperresponsive LHPA axis. Thus, we hypothesized that early RHG would alter the expression of key genes regulating LHPA axis function in adulthood. The present study employed a rat model of insulin-induced RHG spanning postnatal days (P)24-28, a neurodevelopmental equivalent of early childhood in humans, to assess the long-term effects on mRNA levels for proteins relevant to the LHPA function and the corticosterone responses to ACTH stimulation of dispersed adrenocortical cells in vitro and restraint stress in vivo at adulthood. This early RHG model resulted in a hyporesponsive LHPA axis characterized by impaired corticosterone response, increased hippocampal glucocorticoid and mineralocorticoid receptor (GR and MR), decreased hypothalamic corticotropin-releasing hormone, increased adrenal steroidogenic-acute-regulatory protein and GR, and decreased adrenal MR, melanocortin-type-2 receptor and low-density lipoprotein receptor expression. Our findings highlight a complex environmental-gene interaction between RHG and LHPA axis during development that influences regulation of this axis in adulthood. The findings are consistent with the developmental origins of disease and underscore the influences of early-life events on the programming of a major regulatory system.

Iron deficiency in international adoptees from Eastern Europe

OBJECTIVE

To assess iron deficiency (ID) in international adoptees after adoption.

STUDY DESIGN

Participants (n = 37) were adopted into the United States from Eastern Europe before they were 24 months of age. Baseline (within 1 month post-adoption) and follow-up (6 months post-adoption) assessments included routine post-adoption clinical evaluations, anthropometrics, dietary intakes, and iron measures (hemogram and serum analysis).

RESULTS

At adoption and follow-up, mean percent transferrin saturation and mean corpucuscular volume were low compared with the US population. Mean serum ferritin concentration became lower than the US population at follow-up, although the mean daily iron intake was more than the Recommended Dietary Allowance. Participants with Giardia lamblia at baseline had more compromised iron status at baseline and follow-up. Growth rate (change in z-score/months between assessments) was negatively correlated with change in serum ferritin concentrations between baseline and follow-up (r = -0.34; P < .05).

CONCLUSIONS

International adoptees had compromised iron status, with ID more prevalent in participants with G lamblia, a parasite that may interfere with iron absorption. The persistent ID at follow-up was likely caused by the erythropoietic demands of catch-up growth.
