상안검거근 Levator Muscle

[BACKGROUND] Ptosis, the drooping of the upper eyelid caused by levator palpebrae superioris muscle dysfunction, is a common condition that can impair vision and quality of life. It can arise independently or as a secondary condition to dis…

Suspension of the eyelid to the check ligament of the superior fornix for blepharoptosis correction was first reported by Holmström in 2002, yet its exact surgical mechanism remains controversial, with core debates focusing on whether the s…

[BACKGROUND] In blepharoplasty, a preaponeurotic fat pad has been considered to provide padding and structural support for the eyelid. In our practice, we have identified a dense fibrous membrane surrounding the preaponeurotic fat pad, whic…

[BACKGROUND] Full-incision double eyelid blepharoplasty is a widely sought-after procedure in East Asia. However, tarsus-skin or levator aponeurosis-skin fixation techniques may lead to deep folds and scarring. This study aimed to evaluate …

[OBJECTIVE] To investigate the anatomical connections and histological features of the orbital septum in patients with mild ptosis undergoing blepharoplasty. [METHODS] From May 2018 to December 2019, we studied 276 blepharoplasty patients …

The double-eyelid crease formation is primarily influenced by the attachment of the levator aponeurosis to the skin. The buried-suture method of double-eyelid blepharoplasty has gained popularity due to advantages like minimal scarring, fas…

[OBJECTIVE] Through clinical intraoperative observation, gross anatomy and histologic observation, the authors will preliminarily clarify the detailed structures of various tissues related to the upper eyelid opening and closing movement an…

[BACKGROUND] Incidence of iatrogenic upper eyelid retraction (UER) caused by blepharoptosis overcorrection and improper blepharoplasty is increasing fast among Eastern Asians. The aim of this study is to present our experience using techniq…

[SUMMARY] Upper eyelid retraction often results from overcorrection of the levator palpebrae muscle during upper eyelid surgery. In such patients, the time between wound healing and reoperation may be prolonged and could result in symptoms,…

[AIM] This study evaluates the efficacy and safety of botulinum toxin injection for the treatment of upper eyelid retraction in patients with active thyroid-associated ophthalmopathy (TAO). [METHODS] A prospective interventional study was …

[BACKGROUND] Ideal methods for double-eyelid crease creation in Asian upper eyelids remain controversial because of the complexity of the Asian upper eyelid anatomy. Key issues include the underestimation of tarsal height and the septum/apo…

[OBJECTIVE] The purpose of this experiment was to evaluate the functional and histologic changes in the upper eyelid muscles after injection of triamcinolone acetonide (TA) alone or TA combined with botulinum toxin A (Botox or BTXA) in the …

[AIM] We developed a simple bipolar skin and subdermal hemostasis technique called the "Skin Subdermal Adhesion Technique" (SAT), which prevents postoperative complications and provides good cosmetic results. [PATIENTS AND METHODS] We perf…

[BACKGROUND] Cosmetic blepharoplasty is the most common plastic surgery procedures in East Asian and also one of the procedures most prone to unsatisfactory outcomes. The crease width is a crucial aesthetic criterion for individuals seeking…

Upper blepharoplasty for ptosis aims to achieve functional and aesthetic outcomes. However, postoperative eyebrow descent is a potential complication that can affect surgical outcomes. This descent reflects the return of the brow to its nor…

[RATIONALE] Blepharoptosis is a common disorder characterized by abnormal eyelid position that affects both visual function and esthetics. Postoperative upper eyelid retraction, which is often due to overcorrection, is a major problem. Unde…

This study investigates the effects of levator advancement, with and without upper blepharoplasty, on dry-eye symptoms in patients with unilateral ptosis. A total of 92 patients were included, divided into three groups based on surgical int…

[BACKGROUND] The success of upper blepharoplasty depends on both surgeon experience and skill and on patient factors. Therefore, the authors aimed to identify patient-specific characteristics that may contribute to poor prognoses by analyzi…

Upper blepharoplasty is a common aesthetic procedure aimed to address dermatochalasis of the eyelid and improve visual acuity. During the postoperative period, patients may experience complications that are usually minor and transient. Howe…

[BLEPHAROPTOSIS AS AN AESTHETIC COMPLICATION] Eyelid ptosis, or blepharoptosis, following esthetic treatment of the upper third with botulinum toxin Type A (BoNT-A) is a complication with a variable incidence depending on the injector's exp…
