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...

metastatic   tumors in the nose and paranasal sinuses are infrequent. the origin of this metastatic tumors are often renal cell carcinoma. we present one case of metastatic renal cell carcinoma   to the nose and paranasal sinuses ,4 years after initial nephrectomy and diagnosis of stage t1n0m0 clear cell carcinoma. the patient complained of nasal obstruction and recurrent epistaxis   who was tr...

Mucoceles of the paranasal sinuses are locally aggressive, cystic, benign lesions. They mainly occur in the frontal or anterior ethmoidal sinuses, and more rarely in the maxillary sinus. Chronic sinus inflammation, trauma, previous surgery and allergic disease are common causes of paranasal mucoceles. Giant mucoceles of the maxillary sinus causing bone destruction are extremely rare in patients...

PURPOSE OF REVIEW New developments in the nasal and paranasal sinus cancers are reviewed. RECENT FINDINGS In addition to woodworking, several risk factors for nasal and paranasal sinus cancers have been identified, most notably smoking. Progress in the differential diagnosis of small round cell nasal and paranasal sinus cancers allows the precise diagnosis of esthesioneuroblastoma. Despite re...

It is not fully understood why humans possess paranasal sinuses and for many years there has been speculation as to their physiological significance. Much the same uncertainty holds true for the pathophysiology of chronic paranasal sinusitis, a disease which represents a major therapeutic challenge despite recent medical and surgical progress. 3 There are probably several distinct subtypes of c...

fungal sinus infections are being recognized with increasing frequency. we report a case with rhino cerebral and chest phaeohyphomycosis infection caused by cladosporium bantianum in an 18 year old man with wegener's granulomatosis. the diagnosis was established by histopathological appearance, direct examination, culture and computerized tomography (ct) scan. this case was successfully tr...

This study aims to determine the relationship between nasal septal deviation, concha bullosa, and chronic rhinosinusitis by using a definitive pathological and simplified model. Fifty-two consecutive sinus computed tomography scans were performed on patients who received endoscopic sinus surgery and whose final diagnosis was paranasal sinus fungus balls. The incidences of nasal septal deviation...

Background Precise knowledge of anatomic variations of nose and paranasal sinus complex is essential for achieving best surgical results during endoscopic sinus surgery. Computed tomography is the gold standard investigation for evaluation of paranasal sinuses and adjacent structures. Objective To study prevalence of anatomical variations of nose, paranasal sinuses and osteomeatal complex and t...

INTRODUCTION Frontal sinus mucoceles are the commonest among all paranasal mucoceles. With introduction of functional endoscopic sinus surgery, surgeons prefer endoscopic management of sinus mucoceles, but lesions that appear in the lateral part of the frontal sinus can be difficult to access and often need external approaches. CASE PRESENTATION We described a lateral frontal sinus mucocele w...
