1. Eye bag revision surgery is a relatively common cosmetic surgery. The formation of eye bags is closely related to the changes in the tissue structure of the lower eyelid. When there is too much orbital fat, or when the lower eyelid support structure becomes loose and weak with aging, the support structure is insufficient to prevent orbital fat from herniating out, and bags form. Changes in the supporting structures of the lower lid include skin laxity/photodamage, orbicularis oculi muscle laxity/hyperfunction, and orbital septal laxity/orbital fat prolapse. Clinically, lower eyelid aging is divided into four types: simple skin laxity type, orbital septum fat bulge increase type, simple orbicularis oris muscle hypertrophy type, mixed type, of which mixed type is the most common. 2, eye bags surgery traditional skin pathway separation level is divided into: located in the orbicularis oculi muscle skin flap and located in the orbicularis oculi muscle flap, the former in the separation of the skin and orbicularis oculi muscle muscle is susceptible to injury, the formation of hematomas, muscle strength decline. Skin flap muscle lifting effect is poor, myocutaneous flap in line with the normal anatomical level, orbicularis oris muscle and orbital septum between the separation is very easy, less blood vessels, the orbicularis oris muscle damage is small, conducive to postoperative rapid recovery, can maintain the elasticity of muscle fibers and tension. However, after the surgery, the “lower eyelid margin ridge” will easily disappear and the lower eyelid plate will be too flat, which will change the original shape of the eyes and give people a feeling of deadness, and even complications such as eyelid retraction will occur. 3. This surgical method combines the advantages of the flap method and the myocutaneous flap method and has a wider range of indications. The improvements of this procedure are: (1) the shortest path into the orbital septum with an electrosurgical knife, adequate intraoperative hemostasis, and small surgical trauma; (2) the integrity and continuity of the proximal eyelid orbicularis oculi muscle is preserved, which restores the convexity of the lower eyelid margin and makes the shape natural; (3) the elevation of the lower part of the musculocutaneous flap not only strengthens the tension of the orbital anterior wall but also strengthens the support of the orbicularis oculi muscle of the upper part of the lower eyelid and the lower part of the eyeball, preventing complications such as lid retraction and lid ectropion. This not only strengthens the tension of the anterior orbital wall, but also strengthens the support of the upper part of the lower eyelid orbicularis oculi and the lower part of the eyeball, preventing complications such as eyelid retraction and lid ectropion. Lower lid ectropion is a common and serious complication. The biggest advantage of this procedure is that it strengthens the orbicularis oculi muscle and reduces the chance of upper lid ectropion. The orbicularis oris muscle of the myocutaneous flap and the orbicularis oris muscle of the lower eyelid margin are staggered and overlapped during the operation, so that the traction force acts in the downward direction, and the point of action is in the eyelid plate rather than in the eyelid margin, so that it can effectively remove the lid bag, prevent the eyelid margin from ectropion, and maintain the appearance of the original bulge of the orbicularis oris muscle margin. The orbicularis oris muscle should not be lifted too tightly during the operation, so as not to pull the lower lid backward and downward, causing the lower lid to recede, and it is also easy to cut too much skin by mistake, resulting in lid ectropion. Accurate removal of loose skin from the lower eyelid is important for removing wrinkles and preventing ectropion. In patients with simple skin laxity and mixed bags, there are different degrees of lower eyelid skin laxity and wrinkles, and removing or reducing the lower eyelid wrinkles is one of the signs of the success of eye bag surgery. In this paper, the “skin pinching method” was used to determine the amount of skin removal before surgery, and the skin was removed according to the pre-designed method, which has the advantages of accurate skin removal, moderate and uniform, neat incision, and quick and time-saving surgery. The skin clip pinch method is used to determine the amount of skin removal, the preoperative design makes the patient’s upper vision must be exact, and poor skin elasticity and the second surgery should be appropriate to reduce the width of the skin removal. 5, intraoperative dissection of the medial orbital fat bulb artery, removal of the orbital fat body after the electro-knife adequate hemostasis, is to avoid the occurrence of post-bulb hematoma complications and the lower eyelid leveling of the important guarantee. In the literature, there is no description of the course and thickness of the medial orbital adipose bulb artery, but this artery is clinically important in eye bag surgery, and bleeding from this artery can lead to the serious complication of retrobulbar hematoma. Because the middle group of the three groups of orbital fat bodies is more superficial and the medial and lateral groups are deeper, the medial group of orbital fat body arteries was dissected out after opening the orbital septum in this group of surgeries. Clinical practice has shown that this artery is located in the inner and lower part of the medial group of the periosteum, and it is about as thick as the tip of a No. 7 or No. 5 syringe, so it was avoided to remove the excess fat of the inner group with care and then remove the outer fat globe at the end. Check that the adipose tissue is flat (usually flush with the infraorbital rim). The advantage of this method is that it avoids the unevenness of the adipose tissue of the lower lid caused by ligation of the orbital fat body and avoids or reduces the occurrence of the complication of lower lid depression. Because of the intraoperative dissection of the medial orbital fat bulb artery, the occurrence of the serious complication of postbulb hematoma was reduced or avoided. 6. According to the preliminary observation of clinical application, the authors believe that the main points to be noted in the external incision eye bag revision surgery are: (1) the anatomical level should be clear; (2) do not use forceps through the orbital septal incision to reach into the orbit and pull the cellulite outward, which is prone to cause postoperative intraorbital hematoma, and the cellulite should be cauterized to stop the hemorrhage after resection; (3) it should not be assumed that the more the better the resection of the intraorbital fat, which can lead to the concavity of the eye sockets, adhesion, etc. (4) The lower eyelid margin is preserved by retaining the two orbicularis oris muscles with overlapping sutures, which increases the support of the lower eyelid and reduces the occurrence of complications such as lower eyelid recession and ectropion. This minimizes or prevents complications. In conclusion, clear and gentle surgical anatomy, focusing on non-invasive or minimally invasive, reducing intraoperative and postoperative bleeding, is the best way to accelerate postoperative recovery; the correct treatment of the skin, orbicularis muscle and orbital septal fat is a guarantee of satisfactory results of lower eyelid rejuvenation surgery. This method provides physicians with a certain degree of plastic surgery operation foundation with a clear operation, minimally invasive, and with stable efficacy of the eye bag correction and improvement of the operation, which is for reference and promotion.
