BACKGROUND: Chronic rhinosinusitis (CRS) is a downstream complication following radiotherapy or chemoradiation for nasopharyngeal carcinoma (NPC). Endoscopic sinus surgery (ESS) is an accepted therapy for medically refractory CRS, but its efficacy in addressing CRS symptoms in patients with previously irradiated NPC is unclear. METHODS: All patients at the Stanford Sinus Center with a history of radiation therapy or chemoradiation for NPC between 2006 and 2015 were reviewed...

BACKGROUND: Endoscopic medial maxillectomies (EMMs) are used to optimize exposure of the maxillary sinus and retromaxillary areas. Although in type D EMM (Sturmann-Canfield procedure) the anterior superior alveolar nerve (ASAN) is always at risk of injury, only 29% of patients complained of alveolar process and dental anesthesia. The purpose of this anatomical study is to assess the neural anastomotic network of the ASAN (ASAN-NAN) and describe different extensions of type D EMMs in a preclinical setting...

BACKGROUND: Improving the quality of healthcare is a complex and resource intensive process. To optimize the allocation of scarce resources, quality improvement (QI) should focus on high-value diseases that will produce the largest improvement in health system performance. Given the breadth and multidisciplinary nature of sinonasal disease management, the purpose of this study was to transparently develop a prioritized list of sinonasal diseases for QI from the perspective of the specialty of rhinology and the American Rhinologic Society (ARS)...

BACKGROUND: Endoscopic posterior nasal nerve (PNN) resection has been described as an efficacious surgical treatment of allergic and nonallergic rhinitis, but the requirement for surgery under general anesthesia has limited its acceptance. We report the first series of patients treated for chronic rhinitis using a novel device designed for office-based cryosurgical ablation of the PNN. METHODS: Twenty-seven patients with chronic rhinorrhea and/or nasal congestion for >3 months were recruited (allergic or nonallergic rhinitis), with minimum rhinorrhea and/or congestion subscores of 2 as part of the Total Nasal Symptom Score [TNSS])...

BACKGROUND: Patient-reported control of chronic rhinosinusitis (CRS) symptoms is associated with the quality of life impact of CRS. We sought to determine if 22-item Sino-Nasal Outcome Test (SNOT-22) score is predictive of patient-perceived CRS symptom control. METHODS: Prospective cross-sectional study of 202 patients with CRS. Participants were asked to rate their CRS symptom control as "not at all," "a little," "somewhat," "very," and "completely." The severity of patient CRS symptomatology was measured using the SNOT-22...

BACKGROUND: Olfactory dysfunction is 1 of the hallmark symptoms of chronic rhinosinusitis (CRS). Eosinophilic inflammation has been implicated as a potential causative factor. However, prior studies have been limited by retrospective study designs, concomitant use of systemic corticosteroids, and other confounding factors. METHODS: CRS and healthy non-CRS control subjects undergoing endoscopic sinus or skull-base surgery were prospectively enrolled and completed olfactory testing utilizing the 40-item Smell Identification Test (SIT) immediately prior to surgery...

BACKGROUND: Chronic rhinosinusitis (CRS) is a commonly observed sequela after radiation therapy to the paranasal sinuses. The histopathologic features of radiation-induced CRS have yet to be determined and may have major implications in disease management. METHODS: A structured histopathology report was utilized to analyze sinus tissue removed during functional endoscopic sinus surgery (FESS). Histopathology variables, Lund-Mackay score (LMS), and 22-item Sino-Nasal Outcome Test (SNOT-22) scores were compared among patients with radiation-induced CRS (CRSr), CRS without nasal polyps (CRSsNP), and CRS with nasal polyps (CRSwNP)...

BACKGROUND: The diagnosis of allergic rhinitis (AR) is based on cutaneous and serological assessment to determine immunoglobulin E (IgE)-mediated disease. However, discrepancies between these tests and nasal provocation exist. Patients diagnosed as non-allergic rhinitis (NAR) but with positive nasal allergen provocation test (NAPT) may represent a local allergic condition or entopy, still suitable to allergy interventions. The objective of this study was to determine the frequency of nasal reactivity toward allergens among AR and NAR patients, and to describe the diagnostic characteristics of NAPT methodologies...

BACKGROUND: Chronic rhinosinusitis (CRS) is a common inflammatory disorder of the upper airway characterized by chronic inflammation and significant sinonasal remodeling. CRS is comprised of 2 major subgroups, based on whether polyps are present or absent. In some cases, it is characterized by colonization with opportunistic pathogens such as Pseudomonas aeruginosa (PA), Staphylococcus aureus, and other bacteria. The innate immune system of the sinonasal epithelium is the first line of defense against inhaled pathogens...

BACKGROUND: Juvenile nasopharyngeal angiofibroma (JNA) is a benign tumor that presents in adolescent males. Although surgical excision is the mainstay of treatment, recurrences complicate treatment. There is a need to develop less invasive approaches for management. JNA tumors are composed of fibroblasts and vascular endothelial cells. We identified fibroblast growth factor receptor (FGFR) and vascular endothelial growth factor (VEGF) expression in JNA-derived fibroblasts. FGFR influences fibroblast proliferation and VEGF is necessary for angiogenesis...

BACKGROUND: Over the past 20 years, image guidance navigation has been used with increasing frequency as an adjunct during sinus and skull base surgery. These devices commonly utilize surface registration, where varying pressure of the registration probe and loss of contact with the face during the skin tracing process can lead to registration inaccuracies, and the number of registration points incorporated is necessarily limited. The aim of this study was to evaluate the use of novel facial recognition software for image guidance registration...

BACKGROUND: Measuring quality outcomes is an important prerequisite to improve quality of care. Rhinosinusitis represents a high value target to improve quality of care because it has a high prevalence of disease, large economic burden, and large practice variation. In this study we review the current state of quality measurement for management of both acute (ARS) and chronic rhinosinusitis (CRS). METHODS: The major national quality metric repositories and clearinghouses were queried...

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a multifactorial disorder characterized by exaggerated local immune responses. Tumor necrosis factor-α-induced protein 8-like 2 (TIPE2) is a novel protein with potential immune modulating function. The expression and function of TIPE2 in human airway diseases are unclear. METHODS: The expression of TIPE2 in sinonasal mucosal samples was assessed by means of quantitative reverse transcript-polymerse chain reaction, immunohistochemistry, and Western blotting...

BACKGROUND: Dehydration of airway surface liquid (ASL) disrupts normal mucociliary clearance (MCC) in sinonasal epithelium, which may lead to chronic rhinosinusitis (CRS). Abnormal chloride (Cl(-) ) transport is one such mechanism that contributes to this disorder and can be acquired secondary to environmental perturbations, such as hypoxia at the tissue surface. The objective of this study was to assess the technological feasibility of the novel micro-optical coherence tomography (μOCT) imaging technique for investigating acquired MCC defects in cultured human sinonasal epithelial (HSNE) cells...
