canthopexy
Pronunciation: KAN-tho-pek-see
Surgical procedure to tighten or reposition the lateral canthal tendon to correct eyelid malposition.
Full Definition
Canthopexy is a surgical technique used in maxillofacial surgery to address lateral canthal tendon laxity or malposition, often following facial trauma or as part of reconstructive procedures. The procedure involves suturing or repositioning the lateral canthal tendon to restore proper eyelid position and function. It is commonly performed in conjunction with orbital floor reconstruction or zygomatic complex repairs. The goal is to prevent or correct ectropion, entropion, or lateral canthal dystopia while maintaining natural eyelid contour and tear film distribution.
Usage
Usage note: Often confused with canthoplasty, which involves actual tissue reshaping rather than tendon repositioning.
