Sinoscopy: Endoscopy of the Maxillary Sinus: Technique, Common and Rare Findings

Endoscopic examination of the maxillary sinus was introduced in 1902 but only infrequently used in the next half century, partly because of the limited capacity of the optics and light source. The method has been reintroduced and the technique refined in the last 20 years. The development of cold light and Hopkins optics has improved the capability of the method and now makes it possible to make excellent colour photographs for further study, comparison and education. As the method gives information which is often superior to that obtained during clinical and roentgen-examination, it is essential to disseminate the knowledge of the method. The technique used and typical findings are demonstrated in colour photographs.
