canthoplastiacanthopexia

Canthoplastiacanthopexia is a combined eyelid surgical technique that integrates elements of canthoplasty and canthopexia to reconstruct and stabilize the lateral canthus of the eyelid. The term draws from cantho- for the corner of the eye, plastia for reconstruction, and pexia for fixation, reflecting its dual aim of reshaping and anchoring the lateral eyelid region.

Indications for canthoplastiacanthopexia include laxity or malposition of the lateral canthus leading to eyelid malpositions such as ectropion or eyelid instability, as well as cosmetic concerns related to lid contour and the width of the palpebral fissure. It is also employed in reconstructive settings after trauma, tumor excision, or prior eyelid surgery where lateral canthal support is compromised. The procedure is typically performed by oculoplastic or facial plastic surgeons and may be planned as part of broader eyelid rejuvenation or reconstructive plans.

Procedure overview procedures may vary, but generally involve a selective external incision near the lateral canthus to access the lateral canthal tendon. Elements of canthoplasty shorten or reposition the tendon to tighten the lid margin, while canthopexia entails fixation of the canthal structures to surrounding periosteum or the lateral orbital rim to provide durable support. Some techniques employ suturing, grafts, or implants as needed. The approach can be external or combined with a transconjunctival component depending on anatomy and goals.

Outcomes are aimed at improved eyelid position and contour with a lower risk of lid malposition when performed by experienced surgeons. Potential complications include infection, hematoma, under- or overcorrection, lid malposition, scleral show, and rare diplopia. Recovery typically involves swelling management and suture removal within 5 to 14 days.
