Résumé
OBJECTIVE@#To summarize the etiology mechanism and treatment of iatrogenic blepharoptosis after double eyelid surgery in Asia.@*METHODS@#To extensively review the literature related to iatrogenic blepharoptosis after double eyelid surgery, and to summarize and analyze the related anatomical mechanism, existing treatment options, and indications.@*RESULTS@#Iatrogenic blepharoptosis is a relatively common complication after double eyelid surgery, sometimes it is combined with other eyelid deformities such as sunken upper eyelid and wide double eyelid, which makes it difficult to repair. The etiology is mainly caused by improper adhesion of tissues and scars, improper removal of upper eyelid tissue, and injury of a link of levator muscle power system. Whether blepharoptosis occurs after double eyelid surgery by incision or suture, it should be repaired by incision. The principles of repair include surgical loosening of tissue adhesion, anatomical reduction, and repair of damaged tissues. The key is to use surrounding tissues or transplanted fat to prevent adhesion.@*CONCLUSION@#When repairing iatrogenic blepharoptosis clinically, appropriate surgical methods should be selected based on the causes and severity of the blepharoptosis, combined with treatment principles, in order to achieve better repair results.

Objective@#To explore the practicability and reproducibility of judgment method and assessment indexes for the end point of double eyelid surgery using 4+ 1 photography in supine position.@*Methods@#From 2017 October to 2018 October, 158 patients were included and randomly divided into 2 groups. Photos were taken by 4 + 1 photography in supine position of 79 patients, while other 79 patients in control group were evaluated by traditional observation. By 4+ 1 photography in supine position, the surgeon stood at the head side of the patient, taking photos with eyes movement: looking straight forward, looking up, looking downward and eye-closed. It was to observe the upper eyelid creases, upper and lower tissues of double eyelid creases, and upper and lower eyelid margo palpebrae. In addition, the surgeon looked from patient′s feet to observe the indexes such as upper margo palpebrae, to make a decision whether the surgery could finish. In control group, the surgeon observed the upper eyelid creases, upper and lower tissues of double eyelid creases and upper and lower eyelid margo palpebrae. The patient has to sit if necessary.@*Results@#All 158 patients were performed double eyelid surgery successfully. Average times of valuating end point was 1.20 by 4+ 1 Photography in supine position, and 1.53 in control group. The operation time of 4+ 1 photography group is (151.65±21.58) s, and control group were (241.53±33.53) s. The satisfaction level was increased to 89.87% in 4+ 1 photography group, compared to 78.48% in control group.@*Conclusions@#The 4+ 1 Photography method is simple and easy to practice. The observation indexes are accurate and comprehensive. It is useful in determining the end point of double eyelid plasty in supine position.

Objective To explore an effective and hidden incision scar method for epicanthus correction. Methods 80 patients of bi-lateral single eyelid with epicanthus were divided into group A,group B and group C. Twenty-five patients with 50 eyes of group A received“Z” plasty correction of epicanthus,25 cases with 50 eyes of group B received the traditional“Y-V” plasty correction of epicanthus,30 cases with 60 eyes of group C treated with modified “Y-V” plasty correction of epicanthus. The curative effective was observed. Results Three groups were followed up for 6~24 months, the appearances of 25 patients in group A were significantly improved,of whom 2 cases had uni-lateral recurrence,8 cases with obvious postoperative scar. The eyelid shapes of patients in group B were natural after surgery,12 cases with obvious scar. all patients in group C were found no postoperative hypertrophic scars. Conclusion The three surgical treatment were effec-tive for epicanthus,but the design approaches of“Z” plasty correction and“Y-V” plasty correction are more complex,and postoperative scar is obvious,meanwhile the modified “Y-V” plasty correction is simple with incision hidden good shape scar formation.
Résumé
In Asian double eyelid surgery, there have been two approaches to form a suprapalpebral fold: the buried suture (nonincision) method and the full external incision method. Usually excessive fat tissue in upper eyelid has been removed by using a full external incision method, or 2 to 3 partial incisions with buried suture method. The full external incision method is more invasive than the buried suture method, which is not suitable for patients with excessive orbital fat. From March 1999 to January 2002, we have introduced the single 5 mm-partial incision method to 216 patients. This method is applied to patients who have excessive amount of orbital fat or those who do not have excessive orbital fat but which must be removed for better result. These patients have bulging supra-crease areas when we form suprapalpebral folds with a curved wire loop preoperatively. Excessive orbital fat was removed through a single 5 mm incision in the middle of designed eyelid crease and tarso-dermal suture was performed. At another 2 to 3 points, through skin stab punctures by using 18 gauge needle, full-thickness eyelid tarso-dermal sutures were done. Pretarsal and preseptal orbicularis muscles were preserved. If muscles were removed, that could result in thinning of the overlying skin and could make suprapalpebral fold unnatural. This method has several advantages. First, we could perform the operations safely in patients who have excessive fat tissue, without a full external incision. Second,fat tissue can be removed almost totally by a single 5 mm-partial incision. Third, we can minimize the scar formation, and the possibility of complications, and make healing process and operation time shorter compared to the full incision technique. However a very delicate technique is required in this method. In patients who have a thick orbital septum, a superiorly located fat pad, and a bleeding tendency, exposure of fat tissue could be difficult and injury of levator muscle aponeurosis is possible. The complications of this method are the possibility of disappearing of the crease with the lapse of time(3 percents), and suture granuloma formation(less than 1 percent). In conclusion, patients who have excessive fat tissue in upper eyelid don't have to proceed a full incision, and can have more excellent results with this single 5 mm-partial incision method.
