Scalp Fixation in Endoscopic Browlift

Robert G. Fante

Elevation is accomplished by periosteal release at the superior orbital rims and glabella followed by superior stretching at orbital rim.

For some patients, substantial elevation of the medial portion of the brow may be aesthetically undesirable or undesired. For these patients, periosteal release is still performed but fixation using the techniques below may be unnecessary. Instead, a pressure dressing using Reston self-adhering foam (3M) will prevent hematoma and encourage early periosteal re-adherence. Mild superior traction can be applied with Coban or Kerlix wrap (see below).

Fixation of the released and elevated forehead flap is thought to be primarily accomplished by re-adherence of the periosteal flap to the frontal bone. To ensure that it re-adheres at the proper height, intraoperative fixation can be accomplished using several techniques:

Endotine Forehead Bioabsorbable Implant (Coapt Systems, Inc.).

Holes drilled in outer cranial table with special bit provided with device. Holes are placed at desired elevation and through parasagittal scalp incisions to achieve eyebrow contour improvement.

Easier than suture techniques with saving in OR time, but additional expense of implants.

Fixation tines engage frontal periosteum while scalp flap is elevated to desired height. Flap can be lifted from tines and adjusted intraoperatively or within 2 weeks postoperatively in offices.

3.0-mm device for women and men with male pattern baldness, 3.5- mm device for most men and women with thick, heavy scalp.

Carefully wash hair early postoperatively to avoid loss of fixation

Inform patient that implant will absorb in approximately 6 months and will be palpable and/or visible until that time.

Percutaneous titanium screws and staples.

12to 15-mm-long screws, 1.2–2 mm in diameter (Leibinger, W.

Lorenz, etc.).

Placed in outer cranial table at the parasagittal incisions in holes 2–

3 mm deep using stopped drill bit.

Forehead flap is retracted posteriorly while drill hole is made so that the screw passes through the incision with the forehead elevated.

Chapter 79 Scalp Fixation in Endoscopic Browlift 255

Staples bridging the sagittal wounds are placed behind the screw thereby fixating the forehead flap at the desired height.

Screws are removed in the office at 8–14 days.

Advantages include ease of use and intraoperative adjustment.

Disadvantages include risk of scalp necrosis, unsightly scarring, and possibility that periosteal re-adherence will not have taken place by the time of screw removal.

Permanent titanium screws and galeal/periosteal suture.

5-mm-long screws 1.5 or 2 mm diameter (Leibinger, W. Lorenz, etc.).

Placed in outer cranial table at the parasagittal incisions (avoid sagittal sinus in midline) in holes 3–4 mm deep using stopped drill bit.

Forehead flap is retracted posteriorly while drill hole is made.

At anterior end of incision, the periosteum and galea are engaged with long-lasting 2-0 or 3-0 suture on a cutting needle using a buried horizontal mattress technique. Avoid superficial placement.

Screw can be tied to the suture prior to placement in the bone, or the suture can be tied into a knot over an instrument and then placed over the screw head before it is completely tightened.

Advantages include long period of suspension and no need to remove the screw.

Disadvantages include difficulty of placing and tying the suture.

Mitek® (Mitek Surgical Products) anchors and galeal/periosteal suture.

4-mm countersunk screw anchor with preattached suture.

Placed in outer cranial table at the parasagittal incisions in holes 3– 4 mm deep using stopped drill bit.

Forehead flap is retracted posteriorly while drill hole is made so that the screw is passed through the incision with the forehead elevated.

At anterior end of incision, the periosteum and galea are engaged using buried horizontal mattress technique. Avoid superficial placement.

Advantages include relative ease of use, lack of potentially permanently palpable screw head.

Disadvantages include increased cost of Mitek anchor.

Lactosorb (W. Lorenz) screws and galeal/periosteal suture.

5-mm absorbable screw 2 mm in diameter with eyelet for suture

Placed in outer cranial table through the parasagittal incisions in holes 3–4 mm deep using stopped drill bit and then a tap

Forehead flap is retracted posteriorly while drill hole is made so that the screw is placed within the incision when the forehead is elevated.

At anterior end of incision, the periosteum and galea are engaged with long-lasting 2-0 or 3-0 suture using a buried horizontal mattress technique. Avoid superficial placement.

The suture is passed through the eyelet prior to placement of the screw.

256 R.G. Fante

Advantages include relative ease of use, lack of potentially permanently palpable screw head.

Disadvantages include possibility of premature release of the suture, possible tissue reaction, and bone loss.

Bone tunnel and galeal/periosteal suture.

Tunnel created in outer cranial table through which suture is passed to elevate the forehead flap

Medtronics/Xomed Browlift Bone Bridge System assists in creation of bone tunnel.

Forehead flap is retracted posteriorly while bone tunnel is made so that the flap can be elevated.

At anterior end of incision, the periosteum and galea are engaged with long-lasting 2-0 or 3-0 suture using a buried horizontal mattress technique. Avoid superficial placement.

The suture is passed through the bone tunnel prior to tying.

Advantages include relative ease of use, lack of potentially permanently palpable screw head.

Disadvantages include relative difficulty of technique, possibility of diploic bleeding.

K-wire suspension.

Flap is fixated using cutaneous K-wires passed into predrilled holes in the outer cranial table.

K-wires are removed with staples/sutures at 7–10 days.

Occipitalis suspension.

Extra incision(s) created at posterior scalp.

Sutures engage the galea and periosteum at the anterior end of the incision and are tunneled to engage the occipitalis or simply the scalp using a curved suture carrier.

Advantages include lack of potentially permanently palpable screw head.

Disadvantages include relative difficulty of technique, possibility of creating scalp contour deformity.

Closing and Dressing the Wounds in

Endoscopic Browlift

Robert G. Fante

Closing the Wounds

As with any wound under tension, layered closure will provide better scar appearance. It is easy to place several buried interrupted dermal absorbable sutures (e.g., 4-0 or 5-0 Monocryl, Vicryl) at each of the incisions prior to placement of skin staples. For highly visible incisions in men with male pattern baldness, consider meticulous skin closure with 5-0 or 6-0 polypropylene instead of staples.

In patients with moderate to severe skin laxity, consider excision of an ellipse of temporal scalp prior to closure. This will contribute to the appearance and stability of the temporal browlift as the skin laxity will otherwise tend to neutralize the temporoparietal fascia lift.

Dressing the Head

Following skin closure, rinse the hair with warm saline and peroxide mix

(1 liter saline to 8 oz. peroxide) to which baby shampoo may also be added. Ask the nurses for help to avoid making a mess. Consider use of the 3M 1016 drape, which has a built-in fluid collection pouch with suction drain. (This drape can be placed under the patient’s head prior to the prep and will catch all fl uids during the entire case.) Towel-dry the hair, consider detangling spray (e.g., Johnson & Johnson’s for the kids), and loosely comb out any bad snarls. Bacitracin or Neosporin ointment is applied to the wounds.

Compression over the dissected areas prevents hematoma and the need for placement of a drain. It also encourages rapid readherence of the periosteum and temporal fascial layers. Smooth tape can be applied to the forehead, if desired. A typical compression wrap includes fluffs over the incisions, then an axial/coronal wrapping with Coban or Kerlix. Reston foam may also be applied to the forehead skin prior to the

257

258 R.G. Fante

compression wrap. Watch the height and curvature of the brows as any dressing is applied to avoid altering the operative outcome.

The patient is instructed to keep the compression dressing in place for 2 days and then to wear a tennis-type headband for 1 week afterward. If Reston foam dressing/compression wrap is the only method used for central suspension, it is left in place for 5 days. Hair may be washed once the original dressing is removed.

Endoscopic Forehead Rejuvenation:

Avoiding and Managing Complications

Asa D. Morton

1)Alopecia

a)Avoid elecrocautery

i)Incisions

(1)15 blade, one pass through all layers down to outer table of the skull (or through dermis in temporal area)

(2)Tumescent anesthesia of scalp, forehead, and temporal pocket, as well as infiltration of the dermis around incision, minimize need for any cautery

(3)Bipolar better if needed

(4)Attempt to parallel follicles with incision

2)Depressed incisions

a)Ensure good eversion of tissue edges when stapling

b)Incisions in balding patients should be closed with sutures

c)Consider periosteal buried stitch to close deeper layers before closing surface

3)Lagophthalmos

a)Convervative brow elevation in patient with previous blepharoplasty

b)Avoid damage to facial nerve motor fibers to eyelid protractors

4)Scalp itching

a)Less than with coronal incision

b)Associated with nerve regeneration around the incisions or downstream from stretched nerve branches

c)Can be intense and last for several months following surgery

d) Cool compresses may be helpful

5)Neurosensory

a)Most patients experience transient numbness of the forehead and scalp in the distribution of supraorbital and suprarochlear nerves (branches of V1). May also have patchy numbness over temporal area following transection or stretch of the zygomaticotemporal nerve (branch of V2)

b)Facial nerve injury

i)Weakened protractors of eyelid (orbicularis oculii)

ii)Facial nerve at risk in dissecting temporal pocket

259

260 A.D. Morton

(1)Ensure dissection is directly on top of temporalis fascia proper (superficial layer of the deep temporal fascia).

(a)Novice surgeons should verify by making small incision in the fascia, looking for the red muscle fibers

(b)Dissection must be deep to superficial temporal fascia which is layer that facial nerve travels in

(2)More inferiorly it is best to approach the zygoma from within the intermediate fat pad1

(a)Ensures you are deep to the facial nerve

6)Asymmetry

a)Contour and height differences possible

i)Parasagital fixation defines brow arch position

(1)Cautious measurement and preop assessment

b)Vigilance for slipped fixation early postoperatively

7)Infection

a)Usual precautions minimize risk

b)Scalp very vascular, hence low risk

c)Some use prophylactic antibiotics, I do not

8)Hematoma

a)Oozing patients should have drain for 24 hours

i)Rarely necessary in my experience

b)May require aspiration or exploration

c)Meticulous head wrap following surgery very important

9)Bleeding

a)Patients, especially early in the surgeon’s learning curve, should be counseled on the possibility of converting to an open procedure should significant bleeding be encountered

i)Very unlikely

ii)Insulated endocautery and grabbers very effective

iii)Packing for 5 minutes with epi-soaked pledgets useful

b)Careful preop counseling about medicines that can cause bleeding crucial

i)Don’t forget to ask about vitamin and supplement use

ii)Vitamin E must be stopped

10)Cerebrospinal fluid leak

a)Case report in a patient with previous neurosurgical procedure— don’t forget to ask!2

i)Oculocardiac reflex—anesthesia beware!3
