For a long time routine otolaryngological examination could give no more than a rather rough impression of that part surrounding the orbit which is covered by te E.N.T.-specialist, since a close visual study was impossible but for the anterior third of the nasal cavities. Posterior rhinoscopy can give some information about the nasopharynx and choanae, but it is often rendered impossible by the retching reflexes of the patient. Transillumination of the frontal and maxillary sinuses can give hardly any reliable information at all.
