Fifty years ago, the extracorporeal cold light and its transmission by glass fibers, along with the Hopkins rod lens system, were introduced. The development and application of these new technologies to upper airways allowed studying, understanding, and improving knowledge of the anatomy, physiology, and diseases of the nasal cavity and sinuses. In particular, some fundamental concepts of moder...

This is a report of the use of endoscopic sinus surgery in the management of three patients diagnosed with rhino-orbital or rhino-orbito-cerebral mucormycosis. A retrospective review was performed of the clinical examinations and imaging studies of three patients who underwent endoscopic sinus surgery as part of their therapy for mucormycosis. In addition to endoscopic surgery, all patients had...

Recently, functional endoscopic sinus surgery is the state of the art in the surgical treatment of endonasal pathology. For a more accurate access planning including 3D measures of the cavity, especially in complex cases of tumor diseases, a segmentation of the paranasal sinus is certainly a useful tool. Unfortunately, this structure is quite complicated and difficult to segment. In our contrib...

OBJECTIVE To determine the feasible conditions for exclusive endoscopic resection of juvenile nasopharyngeal angiofibroma. DESIGN Retrospective study of 20 patients, with a mean follow-up of 22 months. SETTING Six academic referral hospitals. INTERVENTIONS All patients had a preoperative computed tomographic or magnetic resonance imaging scan and at least 1 follow-up computed tomographic ...

Introduction Functional endoscopic sinus surgery has a long-term high rate of success for symptomatic improvement in patients with medically refractory chronic rhinosinusitis. As the popularity of the technique continues to grow, however, so does the population of patients with postsurgical persistent sinus disease, especially in those with a large window for ventilation and drainage. In additi...

Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinu...
