INTRODUCTION Lower lid blepharoplasty is one of the most complex procedures performed by plastic surgeons. Here we provide a comprehensive and systematic approach to the lower eyelid, which is critical for lower lid blepharoplasty success. PREOPERATIVE PLANNING A thorough ophthalmic history must be taken, specifically as it relates the to use of corrective lenses, glaucoma, allergic reactions, excess tearing, and dry eyes.1 No periorbital aesthetic surgery should take place within 6 months of refractory surgery. Evaluation should include facial proportions, skin type, skin excess, snapback, palpebral fissure size/shape, fat herniation, tear trough, canthal position, extraocular muscle function, Bell’s phenomenon, levator function, margin reflex distance, brow and eyelid ptosis, and globe position relative to malar prominence. (See Video 1 [online], which displays facial analysis.) {"href":"Single Video Player","role":"media-player-id","content-type":"play-in-place","position":"float","orientation":"portrait","label":"Video 1.","caption":"Facial analysis.

In general, the amount of fat removed decreases as you proceed from the lateral to the medial. The lateral deep lower eyelid fat tends to be fuller, more robust, and more vascular. The lateral fat pad is also most likely to be missed.2,3 (See Video 3 [online], which displays transconjunctival removal of lower lid fat.) {"href":"Single Video Player","role":"media-player-id","content-type":"play-in-place","position":"float","orientation":"portrait","label":"Video 3.","caption":"Step 2: Lower Blepharoplasty Technique.

A 5-0 Mersilene (Ethicon, Inc.) suture may be necessary in men with secondary lax eyelids, in cases of dry eyes, and in negative vector patients.2,3 (See Video 4 [online], which displays lateral retinacular canthopexy.) {"href":"Single Video Player","role":"media-player-id","content-type":"play-in-place","position":"float","orientation":"portrait","label":"Video 4.","caption":"Step 3: Lower Blepharoplasty Technique.

Curved scissors are then used to carefully excise the skin, maintaining the underlying orbicularis muscle.2,3 (See Video 5 [online], which displays skin pinch removal.) {"href":"Single Video Player","role":"media-player-id","content-type":"play-in-place","position":"float","orientation":"portrait","label":"Video 5.","caption":"Step 4: Lower Blepharoplasty Technique. Video 5 from “The Five-Step Lower Blepharoplasty Technique Refined”","object-id":[{"pub-id-type":"doi","id":""},{"pub-id-type":"other","content-type":"media-stream-id","id":"0_fvlf3416"},{"pub-id-type":"other","content-type":"media-source","id":"Kaltura"}]} Step 5: Fractionated Fat Injection and Release of the Orbicularis-Retaining Ligament Fat is harvested from the inner thigh with a small multiport cannula. The harvested fat is centrifuged for no more than 1 minute, with the supranatant and infranatant discarded. The remaining fat is then run through a tulip connector at least 50 times to allow for fractionation. This leads to fragmentation of adipose tissue structure. Using a fine 1-mm cannula with a single port, fractionated fat is injected above the periosteum and below the muscle with 50% overcorrection. The medial portion of the orbicularis-retaining ligament needs to be released from its maxillary attachments to blend this transition zone. Release is gently performed laterally using the same fine 1-mm cannula in a blunt manner in the supraperiosteal plane.4,5 (See Video 6 [online], which displays fractionated fat injection and release of the orbicularis-retaining ligament.) {"href":"Single Video Player","role":"media-player-id","content-type":"play-in-place","position":"float","orientation":"portrait","label":"Video 6.","caption":"Step 5: Lower Blepharoplasty Technique.

Imitation des enseignants

Ni prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
