introduction: the association between asthma and sinonasal disease has been established for years. as sinonasal disease is one of the factors that exacerbates asthma, effective treatment of this disorder may also improve and stabilize the asthmatic condition. this study examines the outcome of endoscopic sinus surgery (ess) on asthmatic patients with massive nasal polyposis.   materials and met...

Skull base surgery is evolving from traditional transfacial and transcranial approaches to the endoscopic endonasal approach, a less intrusive corridor for accessing the ventral skull base. This technique eliminates facial scars, expedites recovery, and obviates brain retraction. The goals of surgical excision, whether palliative or curative, are identical: an approach that is less disruptive t...

OBJECTIVES/HYPOTHESIS Patients with a history of sinonasal malignancy can develop chronic rhinosinusitis (CRS) as a consequence of their oncologic treatment. Some patients will fail medical management and require endoscopic sinus surgery (ESS). This study reviews the use of ESS in the management of CRS in patients previously treated for sinonasal malignancy. STUDY DESIGN Retrospective review....

OBJECTIVE To determine whether the 15-degree reverse Trendelenburg position (RTP) during functional endoscopic sinus surgery improves endoscopic field of view and reduces intraoperative blood loss when compared with the horizontal position (HP). STUDY DESIGN A prospective, randomized controlled trial. SETTING St Paul's Sinus Centre, Vancouver, Canada. SUBJECTS Patients with chronic rhinos...

Objectives. Hemangiopericytoma is a rare tumor entity deriving from pericytes. Less than 5% of hemangiopericytoma occur in the nasal cavity and are characterised by a rather benign nature with low tendency of metastasis. However, as the recurrence rate in the literature ranges from 9.5% to 50%-depending on the length of followup-a radical surgical resection is considered as the gold-standard tr...

BACKGROUND Maxillary sinus mucoceles are relatively rare among all paranasal sinus mucoceles. With the introduction of endoscopic sinus surgical techniques, rhinologic surgeons prefer transnasal endoscopic management of sinus mucoceles. The aim of this study is to describe the clinical presentation of maxillary sinus mucoceles and to establish the efficacy of endoscopic management of sinus muco...

OBJECTIVES One of the major challenges of cranial base surgery is reconstruction of the dural defect. Following a craniofacial resection, the standard reconstructive technique is direct suture repair of the dural defect with a fascial graft and rotation of an anteriorly based pericranial scalp flap to cover the dura. The introduction of endoscopic techniques and an endonasal approach to the ven...

Sinonasal actinomycosis should be suspected when a patient with chronic sinusitis does not respond to medical therapy or has a history of facial trauma, dental disease, cancer, immunodeficiency, long-term steroid therapy, diabetes, or malnutrition. Radiological evaluation with computed tomography and magnetic resonance imaging are important in differential diagnosis, evaluating the extent of di...
