Eye socket reconstruction is a surgical treatment for patients with various congenital or acquired causes of eye socket atresia or eye socket narrowing. For example, significant eyelid depression and missing eye deformity caused by eye burns, trauma, tumor resection or congenital malformation ……, thus causing greater mental burden and psychological stress to patients and their families, urgently need to install a prosthetic eye symmetrical to the healthy side. The first thing needed before the installation of a prosthesis is to perform an eye socket reconstruction. Traditionally, there are two types of eye socket reconstruction: non-surgical eye socket expansion and surgical eye socket reconstruction. The eye socket expansion method focuses on groups with congenital anophthalmos or small eyes, etc. Using the elasticity and stretchiness of the normal conjunctiva and skin, small to large eye molds are implanted and slowly expanded with appropriate pressure to form eye sockets large enough to accommodate the normal size and shape. However, due to the limited audience for this method, the success rate is not high. For a much wider range of patients, all need to opt for the surgical method of eye socket reconstruction. The method we use for eye socket reconstruction is to use microsurgical techniques to perform free flap grafting combined with lid reconstruction of the olecranon cartilage to maximize the restoration of the physiological structure and shape of the eye socket and to reconstruct the eyelid to allow for eye opening and closing function close to that of the healthy side. We have accumulated many successful surgical experiences with satisfactory clinical results!
