[Lacrimal duct reconstruction in tumor surgery and following trauma].

Traumatic injuries of the lid often affect the lower lid and the lower canaliculus. Lid destruction by tumours also frequently takes place in the medial part of the lower lid, involving the canaliculus inferior. In order to prevent chronic epiphora the lower canaliculus has to be reconstructed. The most elegant and effective method is the bicanalicular silicon ring intubation (Murube de Castillo). This technique can be utilized in traumatic cases and in tumour surgery. The intubation technique is described and the results are reported.
