Draf IIb procedure is mostly used in a very narrow frontal recess and in a revision frontal sinus surgery. In most cases, the contralateral sinus is not involved. In order to avoid Draf III procedure's reported disadvantages we have commenced the use of the extended Draf IIb procedures in our center. Patients treated with extended Draf IIb procedure at our center between the years 1997 and 2012 were retrospectively evaluated. This procedure includes further widening of the frontal ostium and recces by excising the adjacent most superior nasal septum...

BACKGROUND: Despite advances in endoscopic sinus surgery, frontal sinus obliteration is still indicated in some cases. Current options for obliteration include autologous and synthetic materials. The use of ß-tricalcium phosphate as a resorbable bone graft substitute is a good alternative for frontal sinus obliteration. This study aimed to report our experience with this material. METHODS: A retrospective chart review of patients who underwent frontal sinus obliteration at our clinic between 2008 and 2013 was performed...

INTRODUCTION: Extended endoscopic frontal sinusotomy is often required for surgical management of anterior skull base pathology. Such approaches are necessary for access to pathology and maintenance of postoperative frontal sinus outflow tract drainage. Cold steel instrumentation and endoscopic high-speed microdrills are typically used for bony removal during extended frontal sinus approaches but are associated with certain drawbacks, such as thermal injury and obscuration of the surgical field with bone dust...

Preoperative evaluation of the frontal sinus (FS) and associated anatomical structures may reduce the risk of intraoperative complications and facilitate the management of potential complications. In this study, the authors aimed to evaluate relationship between FS pneumatization and critical anatomical structures. Paranasal sinus computerized tomography scans of 350 sides of 175 patients were evaluated. The pneumatization pattern of the FS, FS dimensions (on the axial, coronal, and sagittal slices), anterior ethmoidal artery, and depth of the of olfactory fossa were evaluated for every patient on both sides...

BACKGROUND: Surgery improves symptoms for the majority of chronic rhinosinusitis (CRS) patients; however, physiological changes in the sinus cavities remain poorly characterized. Direct measurement of changes in airflow, pressure, temperature, humidity, and intranasal spray distribution following surgery is technically challenging. Accordingly, we have used computational fluid dynamic modeling to quantify how these parameters change postoperatively. METHODS: Computed tomography images from a normal control, a patient with CRS preoperatively and postoperatively, and a patient following an endoscopic Lothrop procedure (ELP) were used to create 4 three-dimensional models of the sinus cavities...

Propel and Propel Mini sinus implants are mometasone furoate-coated bioabsorbable stents used as an adjunct in the management of chronic rhinosinusitis after endoscopic sinus surgery. The original sinus implant was deployed in the ethmoid sinuses to provide medialization of the middle turbinate, decrease scarring and mucosal adhesions, limit polyp regrowth, and reduce mucosal inflammation. A structurally smaller version of the Propel, the Propel Mini, was developed and now has been approved for endoscopic placement in the frontal sinuses...
