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...

mucoceles are defi ned as chronic, cystic lesions in the paranasal sinuses. when the mucocele content becomes infected, the lesion is defi ned as mucopyocele. most mucoceles are located in the frontal and anterior ethmoid sinuses and normally they involve the frontal-ethmoid complex, expanding to the superior-medial region of the orbit, leading to ocular disorders; maxillary sinus presentation ...

Cholesterol granuloma (CG) is usually associated with chronic middle ear disease, and is not common in the paranasal sinuses. Additionally, it is very rare for cases of CG to be associated with a fungal infection. However, in this paper, we report a case of sphenoid sinus CG that is associated with aspergilloma in a 78-year-old male patient who presented with right hemifacial pain, headache and...

OBJECTIVE To evaluate by computed tomographic scanning the paranasal mucosal changes of coal workers with and without pneumoconiosis. METHODS Examination of images and scores from paranasal computed tomographic scans. The study participants were 26 coal workers with pneumoconiosis, 29 coal workers without pneumoconiosis, and 20 controls. All were men. The extent and patterns of inflammatory p...

purpose: to present a case of orbital abscess secondary to mandibular odontogenic infection. case report: a 30 year old man presented with ocular pain and exophthalmos of the left eye following a dental infection since a few days ago. a localized abscess was detected in the left orbital ct but the paranasal sinuses were clear. involvement of the left third mandibular molar was evident on facial...

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...

benign fibrous histiocytoma is a rare tumor of nose and paranasal sinuses that originates from histiocytes. ‎‎the main symptoms of patients are nasal obstruction and nasal mass. ‎our patient was presented with chief complaints of nasal obstruction and rhinorrhea non responsive to antibiotic treatment. in computed tomography scan a giant mass in left maxillary sinus and ipsilateral nasal cavity ...

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...

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...
