Blepharoplasty is surgery on the eyelids. It can address heaviness in the upper lids that shadows your vision, and it can soften the bags and hollows that make the lower lids look tired.<\/p>\n\n\n\n

But “eyelid surgery” is really two different operations. Upper blepharoplasty and lower blepharoplasty involve different tissue planes, different incisions, different risks, and different recoveries. Most of the confusion I see in consultation comes from the two being discussed as one procedure.<\/p>\n\n\n\n

This article walks through the anatomy underneath both, so that when we sit down together you already know what the terms mean.<\/p>\n\n\n\n

First: droopy skin and a droopy lid are not the same problem<\/h2>\n\n\n\n

This distinction decides which operation you actually need, so it comes before anything else.<\/p>\n\n\n\n

\"Comparison<\/figure>\n\n\n\n

Dermatochalasis<\/strong> is excess upper eyelid skin. As skin loses elasticity, it folds down over the lash line, and in advanced cases it obstructs the upper part of your visual field. The lid margin itself sits where it should. Removing the redundant skin \u2014 a blepharoplasty \u2014 corrects it.<\/p>\n\n\n\n

Ptosis<\/strong>\u00a0is a low-sitting lid margin. Here the levator aponeurosis, the thin tendon that lifts the upper lid, has stretched or detached from the tarsal plate. The problem is the lifting mechanism, not the skin. Removing skin will not raise the margin; the lid needs the aponeurosis tightened, or in severe cases with poor levator function, suspension to the frontalis muscle.<\/p>\n\n\n\n

The two often coexist. A patient can have hooded skin and<\/em> a low margin, and correcting only the skin leaves them looking half-treated. This is why I measure margin-to-reflex distance and levator function at the first visit rather than simply pinching skin.<\/p>\n\n\n\n

Brow position is the third variable.<\/strong>\u00a0When the brow descends, the upper lid looks heavier than it is. Operating on the lid alone in that situation can pull the brow down further. The periorbital region behaves as one connected unit, and the brow has to be assessed alongside the lid.<\/p>\n\n\n\n

The structures that matter<\/h2>\n\n\n\n

The tarsal plate<\/h3>\n\n\n\n

Each eyelid contains a plate of dense fibrous tissue \u2014 not cartilage, though it feels like it \u2014 that gives the lid its shape and stiffness. The upper tarsus is taller, roughly 10 mm at its centre; the lower is about 4 mm. It is the scaffold the lash line hangs from, and the anchor point for the levator aponeurosis above and the lower lid retractors below.<\/p>\n\n\n\n

Preserving the tarsus is non-negotiable. Almost every technical decision in eyelid surgery is made around it.<\/p>\n\n\n\n

The canthal tendons<\/h3>\n\n\n\n

The tarsal plate gives the lid rigidity, but it does not hold the lid in position. That job belongs to the medial and lateral canthal tendons<\/strong>, which anchor each end of the lid to the orbital rim.<\/p>\n\n\n\n

The lateral canthal tendon is the one that matters most in lower blepharoplasty. If it has loosened with age, the lower lid loses its snap against the globe. Operate on a lax lid without addressing that laxity and you invite the lid to drift downward afterwards \u2014 scleral show, or in the worst case ectropion. Testing canthal laxity before surgery is more predictive of a good outcome than almost anything else I check.<\/p>\n\n\n\n

Where laxity is present, the tendon is reinforced or repositioned \u2014 a canthopexy or canthoplasty \u2014 as part of the same operation.<\/p>\n\n\n\n

The orbicularis oculi<\/h3>\n\n\n\n

This is the sphincter muscle that closes the eye. It runs in concentric bands around the orbit and is responsible for blinking, for the pump that moves tears toward the drainage system, and for protecting the cornea.<\/p>\n\n\n\n

In lower lid surgery the muscle is often lifted, redraped and re-fixed rather than simply removed, because its tone contributes to lid support. Over-resection weakens closure and worsens dry eye.<\/p>\n\n\n\n

The orbital septum and the fat pads<\/h3>\n\n\n\n

Behind the orbicularis lies the orbital septum, a thin fibrous sheet that holds orbital fat inside the socket. With age the septum weakens and the fat bulges forward. That bulge is what you see as under-eye bags \u2014 not extra fat, in most cases, but the same fat pushed forward.<\/p>\n\n\n\n

The upper lid has two fat pads; the lower lid has three. Below the orbital rim sits a separate cushion, the suborbicularis oculi fat, which contributes to the lid\u2013cheek transition.<\/p>\n\n\n\n

The lid\u2013cheek junction<\/h3>\n\n\n\n

The tear trough and the hollow beside it are largely a matter of where the orbital rim ligaments tether skin down. Understanding this is why modern lower blepharoplasty often repositions fat rather than removing it \u2014 more on that below.<\/p>\n\n\n\n

Upper blepharoplasty<\/h2>\n\n\n\n

The incision<\/h3>\n\n\n\n

The incision sits in the natural upper lid crease. Once healed, it is hidden when the eye is open, and visible only as a fine line when the eye is closed.<\/p>\n\n\n\n

The critical decision is how much skin to leave, not how much to take. A minimum of about 20 mm of skin between the brow and the lash line is needed for the lid to close comfortably. Take more than that and the patient is left unable to shut the eye fully \u2014 a difficult problem to reverse. I would rather leave a patient slightly under-corrected and revise later.<\/p>\n\n\n\n

What is removed, and what is kept<\/h3>\n\n\n\n

Skin is the main target. A strip of orbicularis may be taken if the lid is very full. Fat is treated conservatively: the medial pad is often the only one that genuinely needs reducing, and aggressive upper lid fat removal is a common cause of the hollow, skeletonised look that reads as “operated on” rather than rested.<\/p>\n\n\n\n

If the levator aponeurosis has stretched, it is repaired through the same incision at the same sitting.<\/p>\n\n\n\n

Lower blepharoplasty<\/h2>\n\n\n\n

Two routes in<\/h3>\n\n\n\n

Transconjunctival<\/strong>\u00a0\u2014 the incision is made on the inside of the lower lid. There is no external scar, and because the orbicularis and its supporting structures are left undisturbed, the risk of the lid pulling downward afterwards is lower. It suits patients whose main issue is fat bulging with good skin quality.<\/p>\n\n\n\n

Transcutaneous<\/strong>\u00a0\u2014 a subciliary incision just below the lash line, which allows excess skin to be removed as well as fat addressed. It is the route for patients with genuine skin redundancy, and it is usually combined with canthal support.<\/p>\n\n\n\n

Neither is universally better. The choice follows the anatomy.<\/p>\n\n\n\n

Repositioning rather than removing fat<\/h3>\n\n\n\n

The older approach was to excise the bulging fat. It flattened the bag but often left a hollow above the cheek, because the fat was doing volumetric work as well as causing the bulge.<\/p>\n\n\n\n

The alternative is to release the tethering at the orbital rim and redrape that same fat downward over the rim, filling the tear trough with it. Combined with attention to the lid\u2013cheek junction, this produces a smoother transition than excision alone.<\/p>\n\n\n\n

Not everyone is a candidate. Where volume loss dominates, fat grafting or filler may serve better than repositioning.<\/p>\n\n\n\n

How much skin can safely come off<\/h3>\n\n\n\n

Very little, if the lid is not supported. Traditional teaching limits subciliary skin excision to roughly 2\u20134 mm precisely because over-resection is the classic route to ectropion.<\/p>\n\n\n\n

More can be taken safely, but only when the suspension system is deliberately reinforced. In a ten-year series of extended lower blepharoplasty with canthoplasty and muscle fixation, an average of 10 mm was excised with one case of ectropion across 93 patients. The lesson is not “more skin is fine” \u2014 it is that skin excision and lid support are a single decision, not two.<\/p>\n\n\n\n

What I assess before agreeing to operate<\/h2>\n\n\n\n

This is the part of the process that most determines the result, and the part patients hear least about.<\/p>\n\n\n\n
