Surgery of the lacrimal system.

Several surgical techniques of the lacrimal system are presented and analyzed regarding indications and results. Endonasal dacryocystorhinostomy is performed in cases of postsaccal stenosis. Pre- and intrasaccal stenosis are operated on with conjunctivorhinostomy or with placement of Heermann-Jones tubes. After interruption of the canaliculi, splinting and primary suturing are best suited. During tumor surgery, the nasolacrimal duct can be temporarily or permanently relocated in the soft tissues of the cheek. Performing these techniques, a good lacrimal drainage is usually achieved. The results are based upon subjective and objective findings.
