canthoplasty
Pronunciation: KAN-thoh-plas-tee
Surgical reconstruction involving complete detachment and reattachment of the lateral canthal tendon.
Full Definition
Canthoplasty is a more extensive surgical procedure than canthopexy, involving complete division of the lateral canthal tendon followed by repositioning and reattachment to the orbital rim. This technique provides maximum correction for severe eyelid malposition, significant canthal dystopia, or when substantial structural reconstruction is required. The procedure allows for precise repositioning of the lateral canthus and can address both horizontal and vertical eyelid laxity. Recovery typically involves temporary swelling and requires careful post-operative care to ensure proper healing and maintain the desired canthal angle.
Usage
Usage note: More extensive than canthopexy. Specify direction of repositioning (superior, posterior, etc.).
