The following is an analysis of the factors that affect the surgical results of blepharoplasty, which I hope will help you. The orbital sulcus is actually known as the “convex eye”, which is a type of eyelid where the eyeball is relatively prominent. This type of eyelid has little subcutaneous tissue and the orbicularis muscle is not well developed, so it is possible to form a “triple eyelid” during blepharoplasty, and it may also cause incomplete eyelid closure. Therefore, it is best not to perform blepharoplasty on this type of lid shape. If surgery is performed, the width of the eyelid should be narrower than normal. 2. Sagging eyebrows In middle and old age, as the face ages, the skin sags and the eyebrows sag below their normal position, and the tissue in the eyebrow area accumulates on the upper lid, making the upper lid skin very saggy from the surface. If blepharoplasty is used to correct this, it only exacerbates the sagging brow and further reduces the eyebrow-eye distance. It also disrupts the transition of the upper lid skin from the bottom to the top, increasing the span of skin thickness and making the upper layer of the eyelid even more bloated, making the resulting eyelid not only unattractive, but also aggravating the signs of aging. Therefore, if you have a droopy eyebrow, you should first correct the droopy eyebrow and restore the normal eyebrow-eye spacing, and then consider the heavy lids after that. 3. Lid skin wrinkles As we age, some people develop many small wrinkles in the eyelid area, especially in the vertical direction, which have a greater impact on lid shaping for blepharoplasty. The subcutaneous and muscular tissues of these eyelids also have varying degrees of atrophy and degeneration, and the tension and elasticity of the tissue decreases. Therefore, when blepharoplasty is performed, it is difficult to form a beautifully curved blepharoplasty furrow, vertical fine wrinkles with the removal of the skin, inconsistencies in the length of one incision line, and after suturing, the wrinkles are further increased and increased, making the appearance very unsightly. For these types of eyelids, generally do not have blepharoplasty. For aging performance, a lift can be done. 4. Ptosis The partial or total loss of function of the upper eyelid lift can result in an impairment of eye opening, which creates ptosis. There is a difference in the severity of ptosis. It is completely futile to expect blepharoplasty to correct ptosis. The only way to correct it is through surgery such as frontalis suspension and levator shortening. Regardless of the type of surgery, the final result will be a heavy eyelid appearance, but this is not a result of normal anatomical reorganization and is often accompanied by incomplete eyelid closure and a “rabbit eye” appearance, which lacks the dynamic beauty of a normal heavy eyelid. In addition to the above factors, there are also factors such as scarring, secondary blepharoplasty, infection, and of course, the aesthetics and surgical technique of the surgeon. Therefore, we would like to remind those who are ready to undergo blepharoplasty to take into account their own conditions and consult with an experienced surgeon before making a final decision.
