BACKGROUND Mucocoele is histopathologically benign, cystic change of paranasal sinuses filled with mucoid contents, which with its growth is pressuring and destroying local bone walls. In only 3% of the cases it can be localized in maxillary sinuses. Etiology is unknown. Pyocoele develops by secondary infection. CASE REPORT The male patient was 21 years old. His symptoms were runny nose with ...

Infections involving paranasal sinuses and nasal cavities is one of the common public health problem in all age groups. Functional endoscopic sinus surgery has revolutionized in the treatment of sinusitis. MDCT has been the most ideal investigation in the assessment of paranasal sinuses especially in the identification of various anatomical variations that predispose to development of sinus inf...

Abstract Background Antrochoanal polyps (ACPs) are pathologically benign nasal swellings. The maxillary sinus is the commonest reported origin. usually unilateral and often exit through progressively widened ostium to occupy choana may reach nasopharynx. It a disease of adolescents young adults who present with progressive obstruction. Encountering bilateral antrochoanal very rare. Case present...

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...

Introduction: Maxillary sinuses are among the largest paranasal sinuses with various shapes and volumes. The dimensions and volumes of maxillary sinuses play an important role in the surgical treatment plan. The higher levels of pneumatization of alveolar bone lead to the increase of odontogenic sinusitis which cause problems in dental implantation. Therefore, this study aimed to evaluate...

introduction: atypical infratemporal fossa infections are rare and potentially fatal.   case report: a case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. the first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent...

Introduction: The surgical management of chronic frontal sinus disorders remains a challenge for rhinologists. The aim of this study was to evaluate the result of Draf III in a series of patients who underwent this procedure.   Materials and Methods: Twenty patients were included in this study. Demographic data, history of prior surgery, asthma,  aspirin sensitivity and Lund–Mackay score were r...

BACKGROUND Microsensor navigation has the potential to aid balloon sinus ostial dilation by providing real-time tracking of balloon devices within the complex anatomy of the sinonasal cavities. OBJECTIVE This feasibility study evaluated the incorporation of a new microsensor technology into a flexible guidewire for use with current instruments in balloon sinus ostial dilation. METHODS A ret...

OBJECTIVE (1) Become familiar with reported adverse events related to balloon dilation of the paranasal sinus ostia. (2) Understand the sequelae occurring with these events. STUDY DESIGN Retrospective analysis of a prospective database. SETTING OpenFDA database. SUBJECTS AND METHODS The OpenFDA program website of the Food and Drug Administration was queried with the Application Program In...
