In-office, multisinus balloon dilation: 1-Year outcomes from a prospective, multicenter, open label trial.

Background: The objective of this prospective, multicenter study was to assess 1-year changes in sinonasal symptoms and health care use after office-based multisinus balloon dilation.

Methods: Adults diagnosed with chronic or recurrent acute rhinosinusitis per the 2007 adult sinusitis guidelines were enrolled in this Institutional Review Board-approved study. Balloon dilation of the maxillary sinuses/ethmoid infundibula with or without frontal or sphenoid ostial dilation was performed in the physician's office under local anesthesia.

Safety and outcomes following hybrid balloon and balloon-only procedures using a multifunction, multisinus balloon dilation tool.

Background: A multicenter prospective study was conducted to assess the safety and sustained effectiveness of a new instrument possessing multifunctionality as an ostium seeker, suction-irrigator, and malleable balloon-dilator indicated for treating multiple sinuses.

Methods: Endoscopic balloon-only and hybrid-balloon procedures involving dilation of the frontal recesses, maxillary ostia, and/or sphenoid sinus ostia were performed in 175 patients. One-month follow-up was required for all patients.

Accuracy of transnasal cannulation and dilation of the maxillary ostium in cadavers with intact uncinates.

Background: Transnasal cannulation of the natural ostium in patients with an intact uncinate process is complicated by the lack of direct visualization of the ostium. Accuracy of transnasal dilation of the maxillary ostium was evaluated for a malleable-tipped balloon device that was bent to specific angles for avoiding the fontanelle during cannulation.

Methods: Transnasal cannulation and dilation of 42 cadaver maxillary sinus ostia was attempted by 6 surgeons including 3 with very limited clinical experience using the study device.

Epidural abscess masquerading as lateral sinus thrombosis.

Controversy regarding the use of anticoagulants, the evacuation of the sinus, or the use of medical treatment alone surrounds the treatment of lateral sinus thrombosis. Treatment of an epidural abscess associated with coalescent mastoiditis is much less controversial-drainage is usually recommended. The differing treatments of these complications mandate accurate diagnosis.

VOC- and SVOC-emissions from adhesives, floor coverings and complete floor structures.

Unlabelled: Emissions of volatile organic compounds (VOC) and semivolatile organic compounds (SVOC) from materials for flooring installation (primer, screed, adhesive, floor covering) were measured by means of emission test chambers and cells over a time period of at least 28 days at 23 degrees C, 50% relative humidity and an area specific air flow rate of q = 1.25 m(3)/m(2) h. Single components were tested in comparison to three complete structures (same concrete, primer, screed, adhesive) with different types of floor covering (PVC, carpet, linoleum).
