Characteristic change of the eyelid, as people age, is drooping of the palpebral skin, the subcutaneous fat, or the OOM. Although the skin thickness does not always change in proportion to aging [
13], loss of the elastic fibers constituting the skin and skin laxity undergo remarkable alteration as time goes by [
14]. Furthermore, histologically, each layer of the OOM does not always undergo the aging process, such as loss of muscular fibers. Nevertheless, solid adhesion between the orbicularis muscle and skin, the subcutaneous fat layer may show structural weakening due to the aging process [
15]. Droopy eyelid caused by various changes leads to functional disabilities, such as visibility difficulty for Westerners and Asians, as well as the issue of aesthetic discontent. Thus, the efforts to solve such problem made by plastic surgeons have resulted in technical progression and evolvement throughout various ages. As stated above, the classical upper blepharoplasty, the fundamental approach for the management of a droopy eyelid, involves excisions of the excessive, droopy palpebral skin, subcutaneous fats and OOM through incision lines of the pretarsal and lid crease [
1-
4]. This surgical procedure has first been devised and became the foundation of upper blepharoplasty for a long time. This has been attributed to the unique advantage of this surgical method. Owing to the aspect of extirpation being done appropriately throughout the entire eyelid for this method, the medial and lateral perspective of the eyelid can display a relatively even appearance. Moreover, accompanied aponeurotic blepharoptosis may also be corrected without an additional procedure [
5,
6]. Patients with or without a pre-existent double eyelid may be provided with new double eyelids or double eyelids with a desired height [
15]. This procedure also has limitations and disadvantages, nonetheless, which led to development of other methods that have been devised to improve on these drawbacks. Unnatural appearance after surgery may be burdensome for some patients. Particularly, elderly people may not desire newly-formed coquettish eyes. Besides, as aging progresses, it is known that sagging of the skin may be most severe in the lateral 2/3 of the eyelids [
7]. With classical upper blepharoplasty, effective correction of a scar problem may not be easy, and there may be an overhanging problem of protuberant eyelids due to differences in thickness of the pretarsal skin and subbrow skin. Upper blepharoplasty with SE is the procedure devised to improve such limitations of the classical upper blepharoplasty. This procedure, performed through the incision line of the lower border of the eyebrow, may be undertaken without much alteration in facial morphology. A postoperative scar also may not be easily seen by an eyebrow’s borderline. The sagging of the lateral wrinkle can be effectively corrected, while a pre-existent eyelid wrinkle can also be managed without making much change. Hence, this is an effective method for elderly patients who do not desire an operational look. Likewise, this approach may be effective in patients with a pre-existent subbrow incision scar, and in patients who want to change the position of an eyebrow tattoo [
7-
10]. However, this surgical procedure also has its limitations and shortcomings, in that, the drooping of the medial skin cannot be effectively corrected in patients with a problem of eyebrow descend or flattening, shortening of the distance between the eyebrow and lid margin, or severe skin sagging. Since introduction of this procedure by Parkes et al.[
9] for the first time, numerous enhanced surgical techniques have been introduced. Widgerow [
16] has advocated an extended lateral segmental orbicularis excision concomitant with upper blepharoplasty. Har-Shai and Hirshowitz’s [
17] extended upper blepharoplasty for lateral hooding of the upper eyelid, using a scalpel-shaped excision, places more emphasis on the importance of debulking the thick skin and subcutaneous fat laterally, to obtain a pleasing postoperative open appearance to the eyes. Likewise, each approach to upper blepharoplasty has its merits and drawbacks. An excellent result may be achieved by selecting a surgical technique that is suitable for the characteristics of a patient. Clinicians at this department considered a treatment modality that utilizes two surgical procedures performed simultaneously in an attempt to overcome the limitations of each method. SE blepharoplasty has a limitation in that, this procedure cannot be used in patients with severe skin drooping of the eyelid. Particularly in patients with a medial wrinkle drooping of the eyelid. On the other hand, classical upper blepharoplasty has a limitation in making corrections of the excessive lateral wrinkles. On the idea of combination of these two surgical approaches, more effective upper blepharoplasty may be undertaken in patients with relatively severe blepharochalasis. Owing to the fact that each procedure is not so complicated and time consuming, simultaneous performance of these two methods could easily be completed within one hour or so, and does not require technical expertise. Also, the amount of SE was determined by measuring the excessive lateral skin to be excised after the classical upper blepharoplasty had been designed before surgery. Thus, the problem of lagophthalmos by excessive extirpation did not occur, and the droopy skin of the lateral aspect of the eyelids was effectively corrected by using the SE. However, dog-ear, generated by the difference in the excised amount of the medial and lateral aspects, and the tension due to the upper and lower suturing of the eyelid following excessive extirpation, leads to an unnatural appearance of the skin. However, simultaneous excisions of two areas of the OOM may provide more natural looking eyes by natural relocation of the musculo-cutaneous composite tissues between the excised areas of the upper and lower excised area. Besides, owing to the aspect that the excision was simultaneously carried out in two areas, the protuberant fat pad beneath the OOM could easily be removed through the subbrow incision line, while it has an advantage that ptosis correction could concurrently be performed in patients accompanied by aponeurotic blepharoptosis.
