Introduction: Chronic rhino-sinusitis defined as inflammation of the nose and paranasal sinuses. Functional endoscopic sinus surgery (FESS) has now become a well-established strategy for chronic rhinosinusitis refractory to medical

ABSTRACT The Sphenoid Sinus is considered the paranasal sinus with more variation to degree of pneumatization. Thus, this work aimed report first case on interference anatomical for orthognathic surgery. A 18- year-old woman, isolated cleft palate repaired, was submitted surgery correct maxillomandibular skeletal discrepancy. cone beam computed tomography (CBCT) exam performed preoperative plan...

Paranasal sinus anatomical anomalies with unknown etiology are common. Paranasal sinus–related diseases are associated with so high rate of morbidities, it becomes essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool in displaying its anatomy, any anatomic variations and diseases. As paranasal sinus development is a comple...

Background: Chronic rhinosinusitis (CRS) refers to a group of disorders characterized by inflammation of the mucosa of the paranasal sinuses. Nasal endoscopy and computed tomography (CT) scans are successfully used as diagnostic modalities of nose and paranasal sinus diseases. There have been many studies regarding the anatomic variations leading to pathogenesis of paranasal sinus diseases. Con...

BACKGROUND The association between diabetes and paranasal sinus disease has not been thoroughly investigated. METHODS We cross-sectionally investigated the association between diabetes and the presence of paranasal sinus disease, which was confirmed by a head MRI scan in 1350 adults who underwent a health screening program focusing on brain diseases and metabolic syndrome. Logistic regression...

PURPOSE Endoscopic sinus surgery for patients with chronic rhinosinusitis (CRS) unresponsive to medical therapy has traditionally been performed under general anesthesia and in the operating room. Balloons for catheter dilation of paranasal sinuses were introduced in 2005, allowing sinus surgery to be safely performed either in the operating room or the office care setting, under local anesthes...

OBJECTIVES We evaluated the effect of endoscopic sinus surgery on irradiation-induced rhinosinusitis of the maxillary-sinus mucosa among patients with nasopharyngeal carcinoma (NPC). DESIGN Surgical outcomes were evaluated by changes to the ultrastructure of the antral mucosa and nasomucociliary clearance. METHODS Twenty-one NPC patients with irradiation-induced chronic sinusitis were enrol...

OBJECTIVE Immunoglobulin G4 (IgG4) related sclerosing disease (RSD) of the paranasal sinuses is a rare lesion of dense lymphoplasmacytic tissue, with a high proportion of IgG4+ plasma cells. We presented a rare case of IgG4-RSD with isolated involvement of the paranasal sinuses in the absence of multiorgan involvement. METHODS A case report and comprehensive literature review. RESULTS To ou...

Retiform hemangioendothelioma (RHE) is an extremely rare low-grade variant of angiosarcoma that mostly involves the dermis or subcutaneous tissue, but which has never been reported in paranasal sinus. A 53-year-old woman with problems a palpable lump on left lower eyelid and anosmia visited to our hospital. An expansile mass was observed frontoethmoid sinus radiologic images, suspected be attri...
