BACKGROUND: Topical intranasal corticosteroid sprays (INCSs) are standard treatment for nasal polyps (NPs), but their efficacy is reduced by poor patient compliance and impaired access of drug to the sinus mucosa. A corticosteroid-eluting sinus implant was designed to address these limitations in patients with recurrent polyposis after sinus surgery by delivering 1350 μg of mometasone furoate (MF) directly to the ethmoid sinus mucosa over approximately 90 days. METHODS: A randomized, sham-controlled, double-blind trial was undertaken in 300 adults with refractory chronic rhinosinusitis with NPs (CRSwNP), who were candidates for repeat surgery...

OBJECTIVES: Controversy remains regarding the use of deep hypothermic circulatory arrest (DHCA) in neonatal cardiac surgery. Alterations in cerebral mitochondrial bioenergetics are thought to contribute to ischaemia-reperfusion injury in DHCA. The purpose of this study was to compare cerebral mitochondrial bioenergetics for DHCA with deep hypothermic continuous perfusion using a neonatal swine model. METHODS: Twenty-four piglets (mean weight 3.8 kg) were placed on cardiopulmonary bypass (CPB): 10 underwent 40-min DHCA, following cooling to 18°C, 10 underwent 40 min DHCA and 10 remained at deep hypothermia for 40 min; animals were subsequently rewarmed to normothermia...

In the context of the trans crestal maxillary sinus lift, a wide variety of biomaterials have been used to fill the sub-antral space over the years. The materials that have a pasty consistency and are smooth and free from lumps are the most suitable to come into contact with the Schneiderian membrane which, if torn, cannot perform its graft containment function. In this study, a micronized heterologous bone in a collagen matrix of two different percentages was used in order to fill the maxillary sinus. Before using biomaterial as filler, a spray form of hyaluronic acid was used to disinfect the surgical site before and after the surgery, along with more consistent and pasty form of gel of hyaluronic acid being used in order to facilitate the detachment of the membrane...

BACKGROUND: Recalcitrant chronic rhinosinusitis without polyposis (CRSsP) is a challenging condition to manage as traditional medical therapies and surgery fail to provide satisfactory clinical improvements. Colloidal silver (CS), a widely used naturopathic agent, has recently shown anti-biofilm properties both in vitro and within a rhinosinusitis animal model. To date, no trials involving humans have been published in world literature. The purpose of this study was to assess the efficacy of CS as a topical nasal spray in patients with refractory CRSsP...

Generating anatomically realistic three-dimensional (3D) models of the human sinonasal cavity for numerical investigations of sprayed drug transport presents a host of methodological ambiguities. For example, subject-specific radiographic images used for 3D reconstructions typically exclude spray bottles. Subtracting a bottle contour from the 3D airspace and dilating the anterior nasal vestibule for nozzle placement augment the complexity of model-building. So, we explored the question: how essential are these steps to adequately simulate nasal airflow and identify the optimal delivery conditions for intranasal sprays? In particular, we focused on particle deposition patterns in the maxillary sinus, a critical target site for chronic rhinosinusitis (CRS)...

REVIEW
Ahmad R Sedaghat
Chronic rhinosinusitis is an inflammatory disease of the paranasal sinuses that occurs in 1% to 5% of the U.S. POPULATION: It may significantly decrease quality of life. Chronic rhinosinusitis is defined by the presence of at least two out of four cardinal symptoms (i.e., facial pain/pressure, hyposmia/anosmia, nasal drainage, and nasal obstruction) for at least 12 consecutive weeks, in addition to objective evidence. Objective evidence of chronic rhinosinusitis may be obtained on physical examination (anterior rhinoscopy, endoscopy) or radiography, preferably from sinus computed tomography...

PURPOSE: It is common practice to prepare the nasal mucosa with decongestant in children undergoing lacrimal surgery. Xylometazoline 0.05% (Otrivine) nasal spray is commonly used. It has been reported to cause cardiovascular side effects. In the absence of formal guidelines on the safety of the use of nasal decongestants in children, we reviewed our practice to answer the question: How safe is preoperative use of xylometazoline in children undergoing lacrimal surgery? To our knowledge, this is the first study to address the potential side effects of the use of xylometazoline preoperatively in children undergoing lacrimal surgery...
