BACKGROUND: Chronic rhinosinusitis (CRS) is commonly classified into CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). Structured histopathologic reporting has the potential to identify salient histologic markers to differentiate subtypes and provide insights into pathophysiologic mechanisms in CRS. METHODS: A structured histopathology report of 13 variables was prospectively employed to analyze ethmoid sinus tissue removed during endoscopic sinus surgery for 99 patients, including 43 CRSsNP and 56 CRSwNP...

BACKGROUND: Chronic rhinosinusitis (CRS) significantly impacts olfaction. However, the relationship between objective olfaction and patient-reported olfactory-specific quality of life (QOL) is not well understood. Furthermore, objective olfactory testing can be time consuming, so we sought to determine if patient-reported olfactory QOL can be used as screening tool for olfactory dysfunction. METHODS: Olfactory dysfunction was evaluated in 109 patients with CRS using the Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS) and the Sniffin' Sticks Test, assessing for olfactory threshold, discrimination, identification, and overall composite scores (TDI; composite score of threshold, discrimination, and identification)...

Ji-Hyeon Shin, Dong-Hee Lee
BACKGROUND: Identification of aeroallergen sensitization is important for diagnosis and management of allergic diseases. Immunoglobulin E (IgE) sensitization status is known to change over time. However, few studies have explored changes in sensitization patterns across all age groups. The aim of the present study was to evaluate the changing patterns of in vitro IgE sensitization tests in allergic rhinitis patients across all age groups. METHODS: We recruited all patients who were diagnosed as having rhinitis and who underwent in vitro IgE sensitization testing from 2007 to 2016...

BACKGROUND: Episodic or recurrent sinonasal symptoms are often suspected as "sinus" in origin. With normal sinus radiology between events, the diagnosis of recurrent acute rhinosinusitis (RecARS) is made. However, other conditions can produce episodic symptoms. In this study we analyze acutely performed computed tomography (CT) in a population with suspected or self-diagnosed "sinus" disease. METHODS: Patients referred to a tertiary clinic for suspected RecARS were assessed...

BACKGROUND: The role of microbiota in sinonasal inflammation can be further understood by targeted sampling of healthy and diseased subjects. We compared the microbiota of the middle meatus (MM) and inferior meatus (IM) in healthy, allergic rhinitis (AR), and chronic rhinosinusitis (CRS) subjects to characterize intrasubject, intersubject, and intergroup differences. METHODS: Subjects were recruited in the office, and characterized into healthy, AR, and CRS groups...

BACKGROUND: Over the past decade, the use of balloon sinuplasty has increased widely in the United States. Since its introduction, no nationally representative, population-based study has examined its use among chronic rhinosinusitis (CRS) patients. METHODS: We conducted a retrospective cohort study of patients diagnosed with CRS between 2011 and 2014, and compared the prevalence of conventional functional endoscopic sinus surgery (FESS), balloon sinuplasty, and hybrid sinus surgery according to surgical site and calendar year...

BACKGROUND: Major vessel hemorrhage in endoscopic, endonasal skull-base surgery is a rare but potentially fatal event. Surgical simulation models have been developed to train surgeons in the techniques required to manage this complication. This mixed-methods study aims to quantify the stress responses the model induces, determine how realistic the experience is, and how it changes the confidence levels of surgeons in their ability to deal with major vascular injury in an endoscopic setting...

BACKGROUND: Chronic rhinosinusitis (CRS) is a common inflammatory condition and a major cause of olfactory loss. Olfactory dysfunction has been associated with reduced olfactory bulb (OB) volume and gray matter (GM) density in the olfactory-related brain areas. The aim of this study was to investigate brain GM structural and OB volume alterations in patients with CRS. METHODS: Structural brain images were collected from 21 CRS patients and 31 healthy controls on a 3-T scanner...

BACKGROUND: The conventional treatment for idiopathic intracranial hypertension involves weight loss, steroids, diuretics, and/or serial lumbar punctures; however, if the symptoms persist or worsen, surgical intervention is recommended. Surgical options include cerebrospinal fluid diversion procedures, such as ventriculoperitoneal and lumboperitoneal shunts, and optic nerve decompression with nerve sheath fenestration. The latter can be carried out using an endoscopic approach, but the outcomes of this technique have not been firmly established...

BACKGROUND: Endoscopic endonasal nasopharyngectomy(EEN) can be a promising option for select patients with recurrent nasopharyngeal carcinoma, but serious complications can occur in terms of parapharyngeal internal carotid artery (PPICA) injury. Several landmarks have been proposed for locating the PPICA. In this study, we investigated the spatial relationship between the tensor veli palatini (TVP) muscle and the PPICA in a cadaveric model. METHODS: Seven fresh cadaver heads were available for anatomic study...

BACKGROUND: Decreased expression of airway epithelial-specific transcription factor NK2 homeobox 1 (NKX2-1) was associated with allergic inflammation in asthma patients. However, the expression and role of NKX2-1 in nasal polyps (NPs) with different endotypes were undefined yet. METHODS: We examined the expression of key cytokines (interleukin [IL]-4 IL-5, IL-13, and IL-17A, etc.) and NKX2-1 in NPs with different endotypes and control tissues by immunohistochemistry staining, qualitative polymerase chain reaction (qPCR), enzyme-linked immunosorbent assay (ELISA), and Western blot analysis...

Vijay R Ramakrishnan, Benjamin M Milam
BACKGROUND: Ergonomics is the methodologic study of people's efficiency in their work environment and is based on anatomy, physiology, psychology, and engineering. Although highly studied in other work environments, little attention has been paid to surgeons until the landmark survey by Park et al in 2010. Many unique aspects of endoscopic surgery amplify task-related physical discomfort, and, because of these issues, we aimed to study the physical fatigue effects of functional endoscopic sinus surgery (FESS) performed in the standing and sitting positions...

BACKGROUND: Endoscopic sinus surgery (ESS) has become the treatment of choice for a variety of nasal conditions. The purpose of this study was to analyze the effect of diabetes mellitus (DM) on postoperative outcomes in ESS. METHODS: Data on endoscopic sinus surgery performed from 2005 to 2013 were collected from the American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) database. Two groups were created, based on the presence of a DM diagnosis, and were analyzed for preoperative variables, comorbidities, and postoperative complications using SPSS statistical software...

BACKGROUND: Olfactory function deteriorates in patients with severe obstructive sleep apnea syndrome (OSAS). The effect of positive airway pressure (PAP) therapy on olfactory function has not been investigated before. In this study, we aimed to investigate the role of PAP therapy on olfactory impairment in patients with OSAS. METHODS: Thirty patients who had OSAS and planned for PAP therapy were included in the study. All participants underwent a detailed otorhinolaryngological examination and polysomnography...

BACKGROUND: Chronic rhinosinusitis (CRS) is a highly prevalent inflammatory condition, with significant effects on morbidity and quality of life. Given that other chronic inflammatory conditions have been associated with increased mortality risk, we sought to evaluate the relationship between mortality and CRS including the influence of asthma. Our objective was to determine if CRS, with or without asthma, is associated with altered risk of mortality. METHODS: Using a statewide population database, we retrospectively identified 27,005 patients diagnosed with CRS between 1996 and 2012, and 134,440 unaffected controls matched 5:1 on birth year and sex...

BACKGROUND: The unconventional toll-like receptor (TLR) CD180 is implicated in chronic inflammatory diseases; however, its role in chronic rhinosinusitis (CRS) has yet to be investigated. Here we study the expression of CD180, its homologue TLR4 and myeloid differentiation factor 1 (MD1) on mucosal and systemic immune cell populations in relation to serum immunoglobulin G (IgG) levels. METHODS: A total of 70 patients were recruited to the study. Mucosal and peripheral blood samples were prospectively collected from CRS patients and non-CRS controls without evidence of sinus disease...

BACKGROUND: The clinical association between cystic fibrosis (CF) and chronic rhinosinusitis (CRS) is well known. Studies have identified several non-CF transmembrane conductance regulator single nucleotide polymorphisms (SNPs) associated with disease severity in CF patients. We hypothesized that prevalence of these SNPs would be different between CRS patients and age/gender-matched non-CRS controls. METHODS: This is a targeted SNP study of 1231 CRS patients identified through a large university hospital database who were compared with 8796 age- and gender-matched controls without a history of rhinitis, sinusitis, allergies, or asthma...
