Trigeminal trophic syndrome (TTS) is an uncommon condition resulting from trigeminal nerve damage, characterized by persistent facial ulceration, loss of sensation, and paresthesia within the trigeminal dermatome, with ala nasi involvement being a key feature.

This report details three cases of TTS, highlighting periocular changes, with etiologies varying from cerebrovascular accidents to herpes zoster ophthalmicus.
