Local or general anesthesia can be adopted for blepharoplasty surgery. Local anesthesia can be given where simple fat must be removed.
The patient will sit upright with his eyes appropriately placed in a neutral look. The lid crease is located above the ciliary margin 8 to 9 mm in women and 7 to 8 mm above in men. The lower limit of excision should be performed after plugging the eyelid from the lower edge of the forehead to the lateral canthus. The fat location is clearly defined and pre-operatively marked.
With 25 lidocaine and a 27 to 30 gauge needle, the upper eyelids are injected. The skin incision is made. Medial and central are two fat compartments that can be accessed via incisions made in the septum and it can be resected using radiofrequency.
The fat that comes easily into the wound will be removed out of central and medial fats. From the orbit, fat should not be pulled aggressively.
Retro orbicularis oculi fat can be reached beneath the lateral orbicularis that overlies the superior orbital rim. To reduce the heaviness of the upper lid and lateral brow resection has to be done. During wound closure, the sub brow fat pad is repositioned during the closure of the wound with the help of eyelid suspension sutures. With the help of two or three absorbable sutures that can incorporate the orbicularis from the lower and upper edge of the incision along with the superolateral arcus marginalis. The skin incision can be closed with the help of running or interrupted sutures with absorbable or permanent materials or cyanoacrylate glue for achieving aesthetic beauty.
The inferior formix, lateral canthus, and eye skin are anesthetized with 1% lidocaine have epinephrine in transconjunctival lower lid blepharoplasty. An incision is made 4-6 mm below the lid margin through the conjunctiva and lower eyelid retractors. With the help of scissors sharp dissection can be done or with the laser. The fat compartments get prolapsed with gentle pressure on the eyeball and this aids in the identification of the fat pads. The surgeon takes caution so as not to harm the inferior oblique muscle that separates the central fat pocket from the medial one. The incision is kept open and both the inferior and superior edge of the epithelium are opposed well enough to avoid any type of overlap. The incision takes around a week to heal and reveal aesthetic results.
The arcus marginalis is released and the orbital fat is made to advance beyond the infraorbital rim which is underneath the orbicularis muscle with the help of sutures that are temporarily exteriorized in a fat repositioning surgery. Either in a supra-periosteal plane or subperiosteal plane, the fat can be placed which will apparently have no effect on aesthetic results. This method is good at camouflaging the lower orbital rim anatomy and renders a more youthful look to the midface.
