Medial canthal surgery
The medial canthus is key for proper positioning of the lower eyelid to the globe as well as for facial appearance. The medial canthus includes important tendinous structures as well as the proximal lacrimal drainage apparatus. Externally, the medial canthus abuts the medial orbit and nose in a concavity that is highly prone to web formation. Medial canthal surgery is challenging, owing to the complexities in anatomy including the delicate lacrimal outflow structures as well as the highly visible nature. Surgery may be indicated for reconstructive indications-namely eyelid malpositions stemming from age- related, paralytic or cicatricial post traumatic causes. Cosmetic surgery may be desired for epicanthal folds, often in conjunction with blepharoplasty. This chapter details various medial canthus surgeries.
