Endoscopic endonasal assistance with Jones lacrimal bypass tubes

Rigid nasal endoscopy is a reliable technique that can be used to assist in the preoperative nasal evaluation, operative tube positioning, and management after surgery. Postoperative function can be evaluated by using a passive dye test (FEDT) viewed directly, and minor interventions carried out without the need to remove the tube or do excessive probing. Endonasal endoscopy facilitates the maintenance of tube function with minimal manipulation and patient discomfort, and is fast and efficient. Its use should help improve tube retention and function. A detailed study over a number of years is necessary to provide convincing evidence for improving clinical standards. Lester T Jones wrote: The postoperative care of such a patient (having a glass bypass tube) should be in the hands of a physician who is willing to look into the nose, as inspection of the length and position of glass tube is most important. Endoscopic endonasal assistance helps the ophthalmologist to fulfill his criteria.
