inverted papillomas of the nose and paranasal sinuses are uncommon neoplasms, characterized by their tendency to occur and by their association with malignancy. in the past decade there has been a trend toward the use of endoscopic surgical techniques in the management of these tumors. this article presents the results of a prospective study of24 patients with inverted papilloma resected by the...

background and aim . vertical and horizontal bone resorption of the alveolar ridge are common in edentulous jaws. in the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. sinus floor augmentation is an established way of increasing the height and volume of bone in the posterior region of the maxilla, which increa...

b a c k ground: over the past decades, instruments and techniques of the transsphenoidal approach have improved greatly. all of these procedures, whether microscopic or endoscopic, must pass through the sphenoid sinus to reach the lesions. the sphenoid sinus is surrounded by several vital anatomical structures. knowing the details of the anatomy of the sphenoid sinus and the extent of pneumatiz...

background  many biomaterials are used during the open sinus lift surgery, beneath the elevated scheniderian membrane and maxillary sinus bony floor but the search for ideal material continues. methods  in the maxillary posterior atrophic ridges with the bone height less than four millimeters the open sinus lift surgery performed. the autologous platelet-rich plasma (prf) was used as the sole g...

background & importance: the aim of this study was to demonstrate the result of transsphenoid microsurgery for cushing disease in our center and comparing the results in details with other articles, to achieve the best decision for patients management in future. case presentation: between 1991 to 2015, 50 patients suffering from cushing disease were operated. before operation, endocrine tests a...

purpose: to report a patient with exotropia due to medial rectus muscle entrapment as a complication of endoscopic dacryocystorhinostomy (edcr). case report: a 34-year-old female was referred with left exotropia 18 days after edcr for treatment of primary nasolacrimal duct obstruction. she had a large angle left exotropia in primary position as well as complete limitation of adduction and parti...

the silent sinus syndrome (sss) involves painless facial asymmetry and enophthalmos, which is theresult of chronic maxillary sinus atelectasis. in most cases, it is diagnosed clinically, however, usingthe characteristic imaging features including maxillary sinus outlet obstruction, sinus opacification,and sinus volume loss caused by inward retraction of the sinus walls. obstruction of the maxil...
