Endoscopic examination of the nasopharynx.

Endoscopic examination of the nasopharynx is a simple and rapid procedure. The inspection can be made through the nose. This method is recommended for screening. If abnormalities of the nasopharynx are disclosed and are to be studied in detail, and particularly if such abnormalities are to be documented photographically, it is necessary to inspect them through the oropharynx while the soft palate is drawn forward. It is possible under direct vision to take representative biopsy specimens, and it is easy to take photographs for the purpose of documentation, comparison and education. This procedure can to a great extent replace diagnostic excision of tissue from the nasopharynx under general anaesthesia. Especially with a view to early diagnosis of malignant disease of the masopharynx, it is important to extend the use of this method, which can be performed with little discomfort to the patient.
