OBJECTIVES This study assesses the safety and effectiveness of balloon catheters used as instruments in sinus surgery in a "real-world" multicenter registry of 1,036 patients across 27 US otolaryngology practices. METHODS Data were collected by standardized chart review with centralized database administration for all consecutive functional endoscopic sinus surgeries that included the use of ...

Retiform hemangioendothelioma (RHE) is an extremely rare low-grade variant of angiosarcoma that mostly involves the dermis or subcutaneous tissue, but which has never been reported in paranasal sinus. A 53-year-old woman with problems a palpable lump on left lower eyelid and anosmia visited to our hospital. An expansile mass was observed frontoethmoid sinus radiologic images, suspected be attri...

Maxillary sinus floor augmentations were performed by the lateral window technique in 132 sites using betatricalcium phosphate (β-TCP) granules. Cone beam computed tomography (CBCT) scans were taken before surgery, the day of surgery, and one week, three months and one year after surgery. The proportion of the area of the postoperative swelling of the sinus membrane in relation to the remaining...

OBJECTIVES In the paranasal sinus fungal ball (SFB), changes that occur in the underlying bone have not been well described. Recently, bacterial coinfection has been reported in patients with paranasal SFB. We evaluated whether bone changes occur in patients with unilateral maxillary SFB, and also how bacteria in an SFB affect the bony wall of the sinus. METHODS A retrospective study of patie...

BACKGROUND Wound healing after endoscopic sinus surgery may result in adhesion formation. Hyaluronic acid may prevent synechiae development. A systematic review was performed to evaluate the current evidence on the clinical efficacy of hyaluronic acid applied to the nasal cavity after sinus surgery. METHODS Studies using hyaluronic acid as an adjunct treatment following endoscopic sinus surge...

A one-step surgical procedure is presented, including maxillary sinus floor elevation in association with functional endoscopic sinus surgery to remove rhino-sinusal malformations or pathoses that might contraindicate sinus floor elevation. Over a 2-year period, 10 patients requiring a sinus floor augmentation procedure to restore the missing dentition with endosseous implants, but presenting w...

Treatment of frontal sinus disease represents one of the most challenging aspects of endoscopic sinus surgery. Frontal sinus mucocele drainage may be an exception to the rule because in many instances, the expansion of the mucocele widens the frontal sinus recess and renders surgical drainage technically undemanding. Recently, there has been an increased interest in in-office procedures in otol...

We describe an interactive, intraoperative imaging-guided method for performing endoscopic sinus surgery (ESS) within a vertically open MR system. The procedure was performed with intraoperative imaging using a 0.5-T magnet with a 56-cm vertical gap. Interactive control of imaging planes was accomplished by optical tracking with two infrared light-emitting diodes mounted on an aspirator probe. ...

Although augmentation of the maxillary sinus floor with autogenous bone grafts has become a well established preimplantology procedure, its effect on the function of the maxillary sinus has not been the subject of prospective human studies. In this prospective study the effects of sinus floor augmentation on maxillary sinus performance were evaluated. Seventeen consecutive patients who were to ...

Surgical Risks Every decision for therapy involves a risk-benefit analysis and a discussion of potential risks is beneficial for parents in order to put treatment options into perspective. Children probably have lower overall complication rates with endoscopic sinus surgery than adults, perhaps because they usually undergo more limited procedures. For adults, the incidence of serious operative ...
