The number of patients with acquired ptosis is on the rise, and correction of blepharoptosis without any postsurgical scars on the eyelid is desired by most. Despite the advantages of the transconjunctival approach for blepharoptosis surgery, its use has been diminishing. The authors performed transconjunctival levator aponeurotic surgery without resecting Müller's muscle for 21 eyelids in 14 patients with blepharoptosis. In 13 of these patients, 20 eyelids were successfully corrected. No major complications such as entropion, eyelid lag, or persistent irritation of the eye were observed. One eyelid with severe blepharoptosis showed an undercorrection of 1.5 mm. Aesthetic "double eyelid" with symmetric folds was achieved for all but one patient. The advantage is that without a skin incision, the reported method requires less downtime, leaves no conspicuous scar on the eyelid, and meets with marked satisfaction by most patients. It is beneficial for candidates who desire no skin incision but have indications for levator aponeurotic surgery and do not present with excessive upper eyelid laxity. This approach presents some challenges, however. One of these involves determining the degree of aponeurosis advancement according to the degree of the open eye during surgery and creating the desired "double-eyelid" shape and size, especially in Asians. Also, the surgeon needs to gain familiarity with the surgical anatomy of the everted eyelid. This method could, with refinements, become the procedure of choice for the correction of blepharoptosis in selected patients.
获得性上睑下垂患者的数量在不断增加,大多数人都希望在不留下任何术后眼睑疤痕的情况下矫正上睑下垂。尽管经结膜途径进行上睑下垂手术有诸多优点,但其应用却在减少。作者对14例上睑下垂患者的21只眼睑进行了经结膜提上睑肌腱膜手术,未切除米勒肌。在这些患者中,有13例患者的20只眼睑成功得到矫正。未观察到诸如睑内翻、眼睑滞后或眼部持续刺激等重大并发症。一只重度上睑下垂的眼睑矫正不足1.5毫米。除1例患者外,其余患者均获得了具有对称褶皱的美观“双眼皮”。该方法的优点是无需皮肤切口,所需的恢复时间较短,眼睑上不会留下明显疤痕,且大多数患者满意度较高。对于那些希望不进行皮肤切口但有提上睑肌腱膜手术指征且上睑不过度松弛的患者来说是有益的。然而,这种方法也存在一些挑战。其中之一是在手术过程中要根据睁眼程度确定腱膜推进的程度,并塑造出理想的“双眼皮”形状和大小,尤其是在亚洲人中。此外,外科医生需要熟悉外翻眼睑的手术解剖结构。随着技术的改进,这种方法有望成为特定患者矫正上睑下垂的首选术式。
