[Examination of the nose and sinuses].

The nasosinusal diseases are dominated by the rhinosinusitis. Within this framework, the data drawn from the clinical history and the endoscopy are essential. The imaging is here of secondary importance. It is especially useful to assess the extension of the affection and the surgical difficulties which can be encountered in the treatment of the inflammatory or infectious chronic diseases. On the other hand in the event of tumour it can be helpful to determine the etiologic diagnosis and the extension of the disease. The importance of some subjective symptoms as the nasal obstruction will be specified by investigative tests such as the rhinomanometry and the acoustic rhinometry. The etiology of the inflammatory and infectious chronic diseases will be partly established by the study of nasal cytology, the mucociliary testing and the ultra structural study of the cilia.
