Rhinosinusitis is defined as inflammation of the nose and the paranasal sinuses. The symptoms include nasal blockage, loss of smell, nasal discharge, postnasal drip and facial pain. It is defined as acute sinusitis if complete resolution of symptoms is achieved within 12 weeks. If the symptoms persist more than 12 weeks, it is defined as chronic sinusitis.
Examination for sinusitis must include nasoendoscopy. This procedure is performed by ENT specialists under local anaesthesia. The abnormalities include mucopurulent nasal discharge, the mucosal edema with total obliteration of the sinus outlet and nasal polyps will be detected. Besides, the anatomy of the nasal cavity and sinus outlet can also be seen.
CT scan of the paranasal sinuses is useful for assessment of sinusitis. It can detect mucosal changes within ostiomeatal complex and/or sinuses and also opacity of the sinuses and delineate the anatomy of the sinuses.
