Background: Hiding the scars and avoiding hairline displacement are crucial in performing face lift surgery.
Objective: We review temporal and retroauricular flap techniques aimed at avoiding
hairline displacement.
Methods: We introduce a new “high” retroauricular flap, used since 1997, which avoids
the usual transverse retroauricular scar.
Results: The objective of maintaining the hairline has been achieved with this incision.
Conclusions: To diminish hairline displacement and retroauricular scars in face lifts, the
temporal rotation flap and the retroauricular flap with and without a “high” skin flap
are used.

inimizing the sequelae of rhytidectomy is of paramount importance. Too often,
patients return to the consultation room saying they look younger but complaining of unwanted postsurgical sequelae. Three of these particularly undesirable signs are (1) elevation of the temporal hairline; (2) a step in the postauricular
hairline; and (3) a noticeable and sometimes hypertrophic horizontal postauricular
scar.1,2 We present our techniques to overcome these tell-tale signs that indicate an
“operated-on face”3,4 and introduce the use of a new high retroauricular flap.

Temporal Rotation Flap
To elevate the temporal hair in front of the ear, Rees5
proposed in 1980 performing a horizontal triangular
resection below the temporal hairline in cases of secondary face lifts (Figure 1). Since 1983 we have modified
this approach by performing a rotation flap that enables
lowering of the hairline and keeping the deep dermo-fatty
layer to improve the blood supply of the tip of the hairbearing flap.
After the deep layer work has been repaired (superficial
musculoaponeurotic system elevation,6 plication, lipectomy), the key stitch of the skin flap is placed at the posterior tattooed dot and sutured to the cartilage of the
anterior part of the helix. One can then position the temporal flap by use of proper tension and determine at
which level the horizontal part of the hairline will be. In
cases of a low hairline, this can be acceptable, and a simple adjustment is made. In most cases, whether it is a primary or secondary face lift, the hairline is too high, and a
downward rotation will be made to place it back into
normal position. The fold created by the downward rotation helps to determine the width of the excisional triangle. The upper portion is at the limit of the temporal hair,
disregarding the short and sparse hairs often seen below.
The lower line of the incision usually starts 5 mm above
the preauricular key stitch. The anterior angle of the triangle should stay in the horizontal area where the hair
grows downward and should not extend anteriorly.3,4 In
this triangle a deepithelialization is performed with a
number 15 blade, and the edges are approximated with
inverted subcutaneous 5-0 Vicryl® fast absorbable suture.
The superior and posterior edges of the temporal flap are
then readjusted. Because of the downward rotation, it is
often unnecessary to excise any additional hair-bearing
scalp (and that is why we initially perform an incision
parallel to hair follicles, where we incise the temporal
flap). Suturing is performed without tension with 4.0
Vicryl® fast-absorbable sutures in the hair-bearing portion
and 6.0 Prolene® interrupted sutures on the plicated lower
area. The fullness created by the deep-layer plication has
always rapidly subsided, and the use of fibrin glue
(Tissucol, Immuno) helps to flatten and adjust the temporal area. The same approach is used when an endoscopic
forehead lift is combined with a cervicofacial lift.7,8
The Retroauricular Flaps
The incision is vertical from about 4 cm from the helical
root and then becomes horizontal at about the level of
the anterior frontal hairline. The undermining of the flap
is extensive, first in the hairy portion, as deep as possible,
to avoid exposing and damaging the hair follicles. It continues subcutaneously up to the lateral canthus, superficial to the orbicularis muscle, and rejoins the preauricular
undermining (Figure 2). A tattooed ink dot is placed
behind and in front of the preauricular incision at the
level of the anterior extremity of the anthelix of the auricle. This usually corresponds to the level of the horizontal temporal hairline.

The goals are to avoid a step in the retroauricular hairline and a transverse scar in the mastoid skin when the
ear is small or this bald area is wide. Since 1983 we have
used a retroauricular scalp flap to avoid the hairline step.
Starting from the auricular lobule, the retroauricular incision is placed within the sulcus and turns horizontally
across the mastoid area at a level corresponding to the
maximum width of the external ear, usually at the level
of the crus helix, slightly below the anterior key stitch
(Figure 3). The incision is continued horizontally for
about 4 cm and then turns inferiorly at a right angle for

at the level of the frontal hairline. In most patients the lower border of the temporal hair-bearing area is at the level of the helical root. B, The cervicofacial flap is retracted superiorly and posteriorly. The third key stitch (3) is placed at the level of the helical root. Note that the temporal hairline is displaced cephalad. A posteriorly based triangle is designed. The upper edge is placed along the lower border of the temporal hairline. The lower edge is
then drawn from the anterior limit of the upper line to a point within 2 to 3 mm above the level of the helical root. This area is deepithelialized (mottled shading). Adequate mobilization of the temporal area allows caudal rotation of the temporal flap, and the edges of the triangle are closed primarily. This returns the lower border of the temporal hair to the level of the helical root. The excess skin is trimmed (dotted shading). Only a limited
resection is required from the top of the temporal flap. C, The incision is closed without tension.

the direction of the posterior hairline (white arrow). This maintains the continuity of the posterior hairline without producing a step-off. A second key
stitch (C, 2) is placed at the hairline. The excess skin is trimmed (dotted shading). C, The incision is closed. Anterior to the hairline, adjustments must be

about 1.5 cm. Ink dots are tattooed on the ear, hairline,
and flap to allow measurement of displacement and facilitate reapproximation of the natural hairline. The entire
flap is undermined as deeply as possible above the mastoid and cervical aponeuroses.
When the cervical undermining has been completed, we
evaluate the retropositioning of the cervical flap, and in
primary cases, a 0.5-cm strip of skin is usually taken
from the upper border of the flap, with a careful exten-

only the scar.
The backward displacement of the cervical flap is evaluated and a 4.0 Maxon® suture is placed at the tattooed
key point “1” (Figure 3, B). A measurement of the displacement is made.
The next step taken is to reconstruct the hairline by an
upward and backward displacement of the hairy portion.

base of the flap is very wide, it is possible to remove the
upper limit of the flap behind the ear to get rid of these
folds. When the pedicle is not very wide, it is better to
accept the folds, because they will diminish with time
(Figure 4, G).
The High Retroauricular Flap
Since early 1997 we have also used a high retroauricular
flap in certain cases. To avoid the mastoidal horizontal
scar when the ears are small or when the non-hair-bearing retroauricular area is wide, we combine this high
retroauricular flap with the previously described scalp
flap, which restores the hairline (Figure 4). The same
design as for the previous flap is marked at the same
level, but instead of turning the incision horizontally
across the mastoid skin, we follow the retroauricular sulcus up to the limit of the glabrous area and then turn
down to follow the hairline until a horizontal scalp incision is reached. This can be performed only if the width/
length ratio is not smaller than 1:1 (Figure 4, A-D).
The skin flap is carefully raised in continuity with the
scalp flap, keeping it as thick as possible. At the time of
readjustment, the cervical flap is pulled backward and
first sutured at the level of the tattooed ink landmark
behind the ear, marked “1,” as previously described
(Figure 4, B and E).
The hairline is then realigned, and an incision is made
along the hairline on the flap up to the point where the
lower hairline joins the upper hairline (Figure 4, C).
When this point is sutured and the scalp is adjusted, we
carefully adjust the high skin flap, avoiding any tension
(Figure 4, F). An excess of retroauricular skin is created
by the upward movement of the skin flap. When the

Results
We have used the temporal rotation and high retroauricular flaps since 1988.3,4 This series represents patients
who underwent operation between February 1997 and
November 1998 and focuses on the use and complications of the high retroauricular flap. A total of 190 face
lifts were performed (180 women, 10 men). Of these,
116 were primary, 63 were secondary, and 11 were tertiary. Temporal flaps were used in 96 cases, high retroauricular flaps in 28, and 13 patients had a combination of
these. Almost all of the high retroauricular flaps were
performed as part of a primary face lift, and all combined
cases were primary.
Complications were limited to partial superficial or fullthickness partial flap losses or to redundant retroauricular skin folds. Distal superficial partial skin loss occurred
in five patients and healed without further complication.
Two full-thickness partial flap losses were noted, both in
smokers whose flaps had relatively narrow pedicles.
Persistence of retroauricular skin folds was seen in six
cases. Only two patients desired a revision, and these
were performed on an outpatient basis with local anesthetic. The resulting scars have always been of excellent
quality (Figures 5 and 6). The objective of maintaining
the hairline has been achieved.

cated again, associated with various maneuvers to
diminish detectability.9 We use precapillary incisions in
patients who need a significant skin excision and who
already have a receding hairline as a result of previous
surgery. Smokers with fine, fragile hair are also candidates for precapillary incisions. In our experience these
scars are unpredictable; some are hardly visible on one
side yet visible on the other side, even though they are
done in exactly the same way with identical care and
precautions.
Another solution is the zig-zag incision described by
Guyuron,11 following the horizontal part of the temporal
hairline and then ascending vertically behind the hairline.
We use it occasionally in patients who are smokers, have
thin hair, or are elderly. We hesitate to use this incision
in younger patients because the revisions are more difficult and a rotation flap is impossible because of the anterior scar. Elevation of the temporal scalp carries a risk of
hair loss, which is minimized by a deep and atraumatic
dissection and an absence of tension exerted during
suturing. Occasional hair loss may be observed, but the
hair grows back, with the exception of an occasional borderline slough that can be observed in smokers.

In the retroauricular area, the precapillary incision has
very rare indications for us, because we have observed so
many widened and whitish scars. It is only when an
extraordinary amount of skin must be removed that we
would consider this approach; otherwise, we would perform our usual intracapillary incision. Realignment of the
hairline is not always possible. In cases of very extensive
resection (7 cm retroauricular) or in secondary face lifts,
we are obliged to accept a moderate step. The high
retroauricular flap carries a risk. It is a random flap, and
the length/width ratio must be respected, as we have
learned. Therefore it should not be used when the hairline is close to the ear.

Discussion
In the continuous effort to improve results and to minimize sequelae of face lift procedures, the preservation
of hairline and concealment of scars play an important
role.1,2,9,10 In the temporal region, precapillary incisions
have been used for many years and periodically advo-

The best indications for the high retroauricular flap
(Figure 7) are (1) young age, (2) small ears, (3) large
glabrous mastoid area, (4) hairstyle exposing the ears, (5)
male patient, and (6) no previous transverse scar (therefore primary face lifts). Male patients do not usually
require a temporal rotation flap because the beard is in
continuity with the temporal hair. This is not always
true, however, and the hair implantation should be
examined carefully. Occasionally there are only a few
hairs in the preauricular area, and a temporal rotation
flap may be indicated.
Volume 19, Number 3
Scientific Forum
Regarding the retroauricular area, with the usual short
male hairstyles that provide greater visibility around the
ear, the continuity of the hairline and attention to the
quality of scars become even more important. In the
absence of contraindications (especially a narrow pedicle), the high retroauricular flap and realignment of the
hairline are routinely performed.
Conclusions
After 16 years of using the rotation temporal flap and
elevation retroauricular flap, the goal of diminishing the
sequelae of the face lift in terms of preserving the hairline
has been approached. The fact that these flaps are reproducible in cases of secondary and tertiary face lifts is also
of great importance. With the high retroauricular flap,
we are able to further conceal the signs of surgery. Use of
this flap is particularly indicated for young patients with
small ears and a recessed retroauricular hairline. ■
