lifting effect to the neck compared to the high suspension
of the SMAS flap used in a classic facelift. The disadvantage
is that the purse string formed by plication of the SMAS
can result in preauricular fullness in heavier patients. The
[16]
lateral SMAS ectomy offers a solution [Figure 5]. Excision
of a portion of the SMAS overlying the anterior section
of the parotid gland secures the mobile anterior SMAS to
the fixed portion of the superficial fascia. The long axis
of the lentoid incision is oriented such that the vectors
of elevation following SMAS closure lie perpendicular to
the nasolabial fold. This procedure avoids extensive SMAS
flap dissection and elevation, which risks damage to the
buccal branches of cranial nerve VII and tearing of the
flap. In addition, lateral bulkiness is addressed.
DANGER ZONES Figure 4: Open‑sky liposuction of the jowls
Because the SMAS and platysma muscle are not elevated,
and liposuction is preferred to lipectomy, there is no
risk of injury to branches of the facial nerve. However,
injury to the great auricular nerve can lead to a painful
neuroma. Dissection of the skin flap overlying the mastoid
fascia and under the earlobe should be confined to the
reticular layer of the dermis. Sensation in the earlobe
should return to normal or near normal by one week. In
case of neuralgia, repeated injections with ropivacaine or a b
betamethasone may be helpful. Figure 5: Lateral SMAS ectomy, as described by Baker (2,000).

Laceration of the facial vein [Figure 6] leads to bleeding, Vicryl placed after resection
ecchymosis and sometimes hematoma. Coagula can
lead to oozing because of fibrinolysis. They are difficult
to remove because dissection of the tissue planes is
required; following evacuation the epidermis appears lax
and pigmented for a prolonged period. Vein laceration can
be prevented by using Metzenbaum scissors, keeping the
tips parallel to the skin surface and remaining in contact
with the reticular dermis. Retrieving the vein stump after
complete resection can be difficult as it retracts, and for
this reason, bipolar coagulation is used. The vein may
also be punctured by a suture needle when weaving
the loops (the weaving is done with a sertix suture:
suture and needle).
