The cosmetic surgery of the eyelids is performed in adults of all
ages, some patients are operated on to correct problems of aging at
an early age such as 20 or 30 years in both sexes. Blepharoplasty is
the surgery that seeks to rejuvenate the eyelids by remodeling the
periocular tissues. It is performed mainly for aesthetic reasons, but
in some cases only for visual reasons (functional blepharoplasty)
since the skin drop of the upper eyelids can cause a reduction
of the visual field. The aging process causes several changes in
the periocular area. In the upper eyelid are characterized by an
excess and fall of the skin of the eyelid, which causes an aesthetic
alteration but in some cases also causes an alteration of the visual
field of the patient and ocular fatigue due to the weight that the
excess of skin represents for eyelid. This is a condition called
dermatochalasia. Another condition associated with aging is the
presence of a palpebral ptosis caused by laxity of the fibers of the
levator palpebrae superior muscle. In the lower eyelid, the laxity
of the fibro tendinous structures that appear with age causes two
fundamental changes at the eyelid level. On the one hand, the orbital
fat, which occupies a large part of the orbit, is herniated forward,
becoming visible on the skin and giving rise to the known “bags”.
Secondly, the stretching and flaccidity of the skin, orbicular muscle
and tendons of the eyelids give rise to wrinkles, folds and a lower
eyelid descent. Likewise, palpebral positions such as ectropion,
which in turn would produce an alteration in the drainage of the
tear, can also occur in association with aging.
The upper and lower blepharoplasty procedure was performed
20 years ago with a CO2 laser cut, either with the titanium tip or
with the diamond blade and the CO2 laser [1]. Blepharoplasty of
the upper eyelid consists of the removal of excess skin and in some
cases of a part of the underlying orbicularis muscle. Some cases
also require eliminating part of the internal fat package, but always
conservatively. For this surgery, we make incisions with the CO2
laser in the natural folds of the eyelid, which avoid the visibility of
the scars. The technique allows us to remove excess skin, fat [2]
and sometimes muscle without bleeding making the procedure
faster and without residual bruises for the patient. In lower
blepharoplasty we must distinguish between the treatment of the
bags and the treatment of laxity and wrinkles of the skin. We treat
the fat bags of the eyelids by reducing them [3,4]. The reduction of
fat packs is done in patients who have medium or large bags. In the
rest of patients, it may be preferable to reposition them, using the
patient’s own fat to erase the grooves that exist under the bags. In
both cases, the handling of the bags can be done externally, making
an incision in the skin with the CO2 laser, or internally through the
conjunctiva (transconjunctival approach) [5]. The advantages of
the latter are many, including the absence of a visible scar, faster
recovery and greater safety since there is more direct access to the
bags in this way. Finally, the treatment of laxity of the lower eyelid
depends on the severity of this, and we use the resurfacing of the
skin with CO2 or [6] Erbium laser according to the skin tone of the
patient. Sometimes it is also necessary to use techniques for tensing
the eyelid structures such as canthopexy. In some cases, it may be
necessary to remove a small amount of lower eyelid skin [7].
Complications of blepharoplasty are rare when performed
by an expert surgeon. The most serious and infrequent are those
that can affect the vision and the ocular surface, the retraction of
the eyelid [8], or the infection. These can cause dry eye, keratitis
and blindness. Less serious, although more frequent, are the slight
asymmetries, the insufficient correction of the skin or the pouches,
or the conjunctival edema [9,10]. With the transconjunctival
technique we can avoid complications such as ectropion, visible sclera and changes in the shape of the eye and the expression of
the look.
The goal of blepharoplasty is to restore a more youthful
appearance to the eyelid, maintaining the features of each person,
providing a natural appearance, avoiding visible scars and protecting
eye health. The evolution of surgical techniques in recent years has
been the result of better knowledge of facial aging processes. The
most important change has been the adoption of Technology as CO2
Laser and less invasive and more conservative techniques such as
transconjunctival access, seeking greater preservation and more
tissue in the eyelid in order to avoid “empty” eyes or skeletonized.
Blepharoplasty is usually done with local anesthesia, and in many
cases intravenous sedation is also used for greater patient comfort.
General anesthesia is used when at the same time we perform
other more invasive surgeries. The duration of the surgery is very
variable, from 30 minutes to 1 hour generally. The recovery after
surgery is characterized by the appearance of a little edema that
improves with the application of cold during the first week. It is a
usually painless process. The complete recovery can take between
3 and 6 days and the scars improve during 4 to 6 months.
