A patient suffering from epiphora may require which of the following procedures?

In cases of epiphora, which is characterized by excessive tearing, tear duct irrigation is often necessary as a diagnostic and therapeutic procedure. This condition can result from blockages in the nasolacrimal system, preventing tears from draining properly into the nasal cavity. Tear duct irrigation involves flushing the tear ducts with a saline solution to identify blockages.

If a blockage is found during the irrigation procedure, further intervention might be required to remove the obstruction and restore normal tear drainage. This procedure is non-invasive and can provide valuable information about the patency of the tear drainage system.

The other choices pertain to different conditions or treatments that do not specifically address the underlying issue of epiphora. For instance, epilation involves removing eyelashes and is unrelated to tear duct issues. Chalazion surgery focuses on removing cysts from the eyelid rather than addressing tear drainage. Ziegler cautery is a technique used for other purposes, such as controlling bleeding, and is not related to managing excessive tearing. Thus, tear duct irrigation is the most relevant and appropriate procedure for a patient suffering from epiphora.
