Fig. 46.1 Cause and
prevention of lateral
canthus elevation
Summary
Utilization of lateral canthus elevation
• Some young patients desire elevation of the
lateral canthus. For these patients, by design-
ing location of the fourth thread properly,
satisfactory result can be increased.
• Even for middle-aged patients who are
concerned with dropping of the lateral can-
thus or the eyebrows, if the lateral canthus
is slightly elevated by thread lifting, it can
be utilized as a procedure for periorbital
rejuvenation.

47.1
Thread Lifting and Infection
According to Park TH et al., when nonabsorbable
thread lifting was mainly used in the past, cases
of chronic inflammation like foreign body granu-
loma as well as infection occurred in low
incidence.
Wu et al. discussed that infection or granuloma
formation can occur during thread lifting proce-
dure. However, fortunately, the most complica-
tions such as infection are not severe and can be
treated easily. However, Benny Yau et al. reported
a case of Mycobacterium abscessus infection
after performing a thread lifting procedure on the
face. It is an important case which shows severe
infection can occur although it is rare.
Infection after absorbable thread lifting is
evaluated to be less frequent than infections after
nonabsorbable thread lifting. If the operating
room maintains good hygiene, infection on the
thread insertion area does not occur easily.
Also, in case of the PDO (polydioxanone)
which is used the most in absorbable thread lift-
ing, it can be manufactured with smooth surface
and in the form of monofilament. Therefore, it
tends to have higher resistance against infection
relatively.
However, recently, cases of mycobacterium
infections were reported after PDO thread lifting
procedures in Korea. Shin Jung Jin et al. reported
a case of a 47-year-old woman who came in with
erythematous plaque on both sides which
occurred in the second week after the procedure
from a nonmedical practitioner. The patient was
treated with antibiotics for 1 week at a local clinic
and transferred to general hospital, and it was
finally diagnosed as Mycobacterium massiliense
infection.
Therefore, medical practitioners should keep
in mind all possibilities of infections and try to
maintain a sterile environment before and after
procedures.
47.2
Prevention of Infections
To prevent infections, areas around entry points
must be disinfected thoroughly, and aseptic tech-
nique should be used during the procedure.
• Disinfect entry points.
• Disinfect all of the skin area within the range
of cannula manipulation.
• If there is hair within the access of cannula or
if insertion is done inside the scalp, hair must
be prepared using suitable tools.
• Hair must not be dragged into the entry points
during the procedure.
• After the procedure, check once more whether
any hair got in the entry points.
• Education for prevention of infections at the
entry points and the exits.

47.3
Treatment
Infection after thread lifting procedure is gener-
ally treated easily by taking antibiotics.
However, in rare cases, as mentioned above,
mycobacterium infection needs a long-term
treatment with intravenous antibiotics and
drainage process.
In case of infection which is irresponsive to
antibiotics treatment, transferring a patient to the
general hospital must be considered and aggres-
sive treatment is required.
In the case of Mycobacterium massiliense
infection, as mentioned above, a long-term treat-
ment with clarithromycin and amikacin was done
after drainage.
