In-office, multisinus balloon dilation is safe, effective, and well tolerated. Patients reported significant reductions in both sinonasal symptoms and health care use after balloon dilation. Efficacy observed at 1 and 6 month follow-up was sustained through 1 year with a very low rate of revision surgery. This study was a part of the clinical trial NCT01612780 registered at www.clinicaltrials.gov.
These results indicate that a multifunctional, malleable, balloon-dilating device can be safely and successfully used to treat multiple sinuses with sustained ostial patency and symptom improvement for at least 1 year.
Objectives: To define the postoperative time interval required for elevated periosteum to readhere to the skull and regain its preoperative strength, and to evaluate whether fixation of the periosteum affects this interval or the strength of postoperative readhesion.Design: Prospective analysis of variance and covariance with repeated measures.Subjects: Thirty-six New Zealand white rabbits, each serving as its own control.Interventions: Subperiosteal elevation was performed on one side of the skull, leaving the contralateral periosteum untouched. The periosteum in half of the subjects was lifted and fixed to a resorbable screw, with the comparison group undergoing subperiosteal elevation only, without lifting and fixation. Several adhesion characteristics were subsequently examined at postoperative weeks 1, 3, 5, 7, 8, 9, 10, 11, and 12. Half of the subjects were assessed histologically to determine attachment of periosteum onto underlying bone. The other half underwent analysis of periosteal readhesion strength.
Results:The 3 independent measures of periosteal adherence to the skull all lacked significant differences between sides after the first postoperative week. Blinded histologic analysis showed no evidence of ongoing periosteal healing and demonstrated no difference between operated-on and nonoperated-on sides. Analysis of periosteal stiffness (P=.76) and energy density (P=.74) also demonstrated no significant differences between sides.Conclusions: Periosteal readhesion after surgical elevation is virtually complete by the seventh postoperative day. In addition, tension secondary to periosteal elevation with suspension has no influence on postoperative healing. These findings will contribute to the debate regarding the most appropriate brow-lift fixation technique.
Using recommended procedural techniques and a malleable-tipped balloon device, newly trained and experienced physicians alike can perform uncinate-preserving transnasal cannulation and dilation of the maxillary ostium with a high rate of success.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
