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...

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...

BACKGROUND: The indications for surgical management of chronic rhinosinusitis (CRS) in patients with cystic fibrosis (CF) are poorly defined. In this study we compare outcomes of medical versus surgical treatment and examine trends associated with the transition from medical to surgical therapy in CF patients. METHODS: One hundred thirty-six patients with CF referred to a tertiary rhinology practice were retrospectively divided into 3 cohorts: Medical, Upfront Surgery, or Crossover, if they converted from medical to surgical management...

BACKGROUND: Management of frontal sinus trauma includes coronal or direct open approaches through skin incisions to either ablate or obliterate the frontal sinus for posterior table fractures and openly reduce/internally fixate fractured anterior tables. The objective of this prospective case-series study was to evaluate outcomes of frontal sinus anterior and posterior table trauma using endoscopic techniques. METHODS: Prospective evaluation of patients undergoing surgery for frontal sinus fractures was performed...

BACKGROUND: Squamous cell carcinoma (SCC) of the sinonasal cavity is a rare entity that arises as either de-novo tumors or from inverted papillomas (IPs). In this study we evaluate and compare oncologic outcomes of sinonasal SCCs based on their etiology and treatment strategy. METHODS: This investigation was a single-center, retrospective review comparing de-novo SCCs (n = 28) and those associated with IPs (n = 38) resected during the period from 2000 to 2015. Demographic and tumor data, surgical approach, recurrence, and clinical outcomes were analyzed...

BACKGROUND: The impact of endoscopic sinus surgery (ESS) on pulmonary function in cystic fibrosis (CF) patients with chronic rhinosinusitis remains unclear, as studies have demonstrated conflicting results. To date, no study has looked specifically at the impact of CF genotype on lung function after ESS. In this study, we reviewed changes in pulmonary function test (PFT) results after ESS in F508del homozygotes and heterozygotes. METHODS: The charts of 25 patients with CF without prior lung transplant, who underwent ESS performed by the same surgeon between the period of July 2005 to July 2015, were retrospectively reviewed...

BACKGROUND: Acute invasive fungal rhinosinusitis (AIFRS) represents a fulminant, potentially fatal, disease process in immunocompromised patients. The diagnosis often rests on high index of clinical suspicion, with relative paucity of data on the diagnostic and therapeutic implications of intraoperative frozen sections. METHODS: Retrospective review was performed for 18 cases undergoing endoscopic sinus surgery for AIFRS. Reliability of intraoperative frozen section diagnosis was evaluated for all patients using final pathology as the gold standard...

BACKGROUND: Chronic rhinosinusitis (CRS) is a common condition for which there are numerous medical and surgical treatments. The 22-item Sino-Nasal Outcome Test (SNOT-22) is a patient-reported outcome measure often used with patients diagnosed with CRS. However, there are no utility values associated with the SNOT-22, limiting its use in comparative effectiveness research. The purpose of this study was to establish utilities for the SNOT-22 by mapping responses to utility values associated with the EuroQol-5-dimensional questionnaire-3-level version (EQ-5D-3L)...

BACKGROUND: For allergy immunotherapy to be effective, patient compliance is critical. However, aqueous sublingual immunotherapy (SLIT) may be considered demanding for patients, requiring strict daily dosing and refilling of medication at regular intervals. In this study we sought to determine how patients perceive their own compliance with SLIT and identify barriers that may hinder compliance. METHODS: Using a retrospective review, 46 patients currently undergoing aqueous SLIT were identified to have less-than-excellent compliance based on frequency of clinic visits for SLIT refills...

BACKGROUND: Although short-term use (≤2 months) of atomized topical nasal steroids has been shown to be safe and effective, the long-term safety has yet to be demonstrated. The aim of this study was to determine the impact of long-term topical budesonide treatment via the mucosal atomization device (MAD) on the hypothalamic-pituitary-adrenal axis (HPAA) and intraocular pressure (IOP). METHODS: A cross-sectional study of patients with chronic rhinosinusitis (CRS), with or without nasal polyposis, managed with daily nasal budesonide via MAD was conducted at a tertiary rhinology center...

BACKGROUND: To sustain the long-lasting beneficial effects of allergen-specific sublingual immunotherapy (SLIT), an adequate duration of treatment is required. Nevertheless, many patients discontinue prematurely and therefore fail to obtain satisfactory therapeutic effect in clinical practice. The aim of this study was to analyze the causes leading to premature discontinuation of SLIT in allergic rhinitis (AR), and to provide the corresponding countermeasures for the following SLIT course...
