This paper reports a case of septic cavernous sinus thrombosis following a chronic ear infection and paranasal sinusitis. The diagnosis and management of this condition are discussed.

Topical drug delivery to poorly ventilated paranasal sinuses is challenging. Pulsating aerosols can improve the deposition of drugs like cortisol in sinuses. The current study compares effect Budesonid administered as pulsating aerosol comparison conventional nasal spray

objectives: new digital two-dimensional imaging systems are considered as an easily accessible modality for sinonasal evaluation. the aim of this study was to assess the diagnostic efficacy of digital waters’ and caldwell’s radiographic views for evaluation of sinonasal area. materials and methods: a total of 273 patients fulfilling the inclusion criteria were enrolled in this descriptive-analy...

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...
