[Lacrimal canalicular transposition for lower canaliculus repair: About four cases].

The main function of the eyelids is to support and protect the globe. The lower eyelid and medial canthus are often the location of malignant tumors that can be locally aggressive and require disfiguring surgeries. Chronic epiphora often appears in cases of inadequate reconstruction in this location and can require secondary procedures. We report four cases of medial canthus repair after tumor removal with loss of the inferior canaliculus. The ipsilateral superior canaliculus was removed before being transposed into the lower eyelid. This simple method allows for complete canalicular reconstruction. It obviates the need for artificial material and its potential associated complications. It has the advantage of a one-step eyelid and canalicular reconstruction and prevents epiphora after tumor resection.
