6、iva as a composite flap.Twenty-one(42 percent)of those patients also underwent split V-W epicanthoplasty and plication of the medial canthal tendon for epicanthal folds with associated telecanthus.Degree of ptosis and levator function were measured preoperatively and postoperatively.,9,Results,Compl
7、ete or near-complete correction of ptosis(degree of ptosis,1 mm)was achieved in 54 eyelids(63.5 percent)and mild residual ptosis轻度残余下垂(degree of ptosis,1 to 2 mm)was observed in 22 eyelids(25.9 percent)in postoperative follow-up after 6 months.The most common complication was reoperation,which was d
8、one in 15 eyelids(17.6 percent)because of incomplete correction.,10,Conclusions,The advancement technique using the levator aponeurosisMllers musclelamina propria mucosa of conjunctiva composite was effective in the treatment of severe blepharoptosis with levator function of 2 to 7 mm.The technique
9、produced elevating motion of the physiologic eyelid in a superior-posterior direction.There were no serious complications,such as long-term lagophthalmos(睑闭合不全)or lid lag(眼球迟滞).,11,Severe ptosis presents a difficult condition because a significant amount of eyelid excursion is required to correct it
10、.In addition,in congenital ptosis,levator muscle function is often poor.We define severe ptosis as the degree of ptosis greater than 4 mm,as described by Isaksson.,12,Frontalis suspension is commonly performed to bypass the issue of poor levator muscle function.However,there are many drawbacks assoc
11、iated with frontalis suspension,such as lagophthalmos,lid lag,lid distortion,and unnatural eyelid movement in a superior direction following overaction of the frontalis muscle.Holmstrm and Santanelli reported on suspension of the eyelid to the check ligament of the superior fornix in congenital blep
12、haroptosis.,13,The check ligament of the superior fornix(上穹窿),which emanates from the sheaths of the levator and superior rectus muscles and from Tenons capsule,contains collagen fibers,elastin fibers,and smooth muscle fibers.Superficial and deep extensions of the check ligament continue to the supe
13、rior conjunctival fornix and conjunctiva.This check ligament was confirmed by Lukas and colleagues and Hwang and colleagues as the intermuscular transverse ligament(肌间横韧带)and conjoint fascial sheath(CFS,联合筋膜鞘),respectively.,14,15,Kakizaki and colleagues classified the conjunctiva into lamina propria
14、 mucosa of conjunctiva and conjunctival epithelium.The lamina propria mucosa of conjunctiva is located just posterior to the Mllers muscle and has a rich vascular plexus.The lamina is as thick as Mllers muscle and inserts onto the posterior half of the superior tarsal border.The lamina continues pro
15、ximally to the check ligament and is thought to have a suspensory effect on the upper eyelid.,16,We used the levator aponeurosis,Mllers muscle,and lamina propria mucosa of conjunctiva in the treatment of severe blepharoptosis.In cases of epicanthal folds with associated telecanthus,epicanthoplasty a
16、nd medial canthal tendon shortening(内眦韧带缩短)were performed simultaneously to enlarge the palpebral opening and to release the tension of the upper medial eyelid skin and tethering fold,which impedes(阻止)the action of eyelid elevation.,17,PATIENTS AND METHODS,Between January of 2004 and September of 20
17、12,we recruited 50 Korean patients with severe blepharoptosis(degree of ptosis,4 mm)for this study.The 50 patients(85 eyelids)underwent the advancement technique using the levator aponeurosisMllers musclelamina propria mucosa of conjunctiva composite flap.Twenty-one of 50 patients(42 percent,42 eyel
18、ids)had epicanthal folds with associated telecanthus and therefore underwent epicanthoplasty and shortening of the medial canthal tendon.,18,Operative Technique,The double eyelid incision line is marked on the upper eyelid 6 to 9 mm above the lid margin,depending on the personal preference of patien
19、ts without double eyelids.Modified V-W plasty is designed on the skin medial to the epicanthal folds of patients with blepharoptosis and epicanthal folds with associated telecanthus.Epicanthal folds with associated telecanthus are corrected before ptosis correction is performed.The operation is usua
20、lly performed with the patient under local anesthesia with intravenous or oral sedation.,19,20,Correction of Severe Blepharoptosis,An incision is made along the double eyelid mark after subcutaneous infiltration with 1%lidocaine with 1:100,000 epinephrine.Epinephrine is omitted during deeper injecti
21、on to prevent stimulation of the Mllers muscle.The upper anterior surface of the tarsal plate and the orbital septum are exposed after excision of pretarsal soft tissue.The orbital septum is cut at its lowest part and the protruding orbital fat is partly excised to expose the levator aponeurosis.Tet
22、racaine(丁卡因)eye drops are applied to the cornea(角膜),and corneal eye protectors are applied to the globe.,21,The levator aponeurosis,Mllers muscle,and lamina propria mucosa of conjunctiva are then detached carefully from the superior tarsal border and underlying conjunctival epithelium with sharp iri
23、s scissors with the help of these three traction sutures.Injection of pure lidocaine into the superior portion of the tarsus facilitates the detachment of the Mllers muscle and the lamina from the superior tarsal border and the conjunctival epithelium by causing the tissues to balloon up slightly.In
