P R EOPERAT IVE EVALUAT I O N
A n individual ized treatment plan designed to m i n i m ize sur­
gica l risk is essenti al . The goa l is a youthfu l and natura l post­
operative result. A strategy should be formu lated for eac h of
the three facial zones as well as each ind ividual non-facial
regio n , as each a natomic region req ui res a specific man­
agement which influences the rema i n i ng a natomic regions.

Treatme nts for photoaging ra nge fro m nona blative laser

tec h n i q ues a re d escri bed in d eta i l in previous cha pters.
Put s i m ply, the m ost effective lasers, carbon d ioxi d e
a n d e r b i u m a blative res u rfa c i ng lasers , provid e the m ost
d ra matic benefit for photoaging a n d other s k i n co n d i ­

They rema i n the gol d sta n d a rd treatment for photod a m ­
aged ski n . Dramatic res u l ts, however, ca n be seen with
one treatment. Side effects i n c l u d e prolonged erythema
(fo r months ) , perma nent hypopigmentat i o n , te m pora ry
hyperpigmentat i o n ,
i nfect i o n ,
and
sca r.
Ad d itional ly,
d ownt i m e from work a n d soc i a l a ctivities is sign ifica nt.
For this reaso n , the po p u l a rity of a blative lasers has
decreased d ra matica l ly over the past seve ra l yea rs
a mong patients a n d physicians.
By contrast, nona blative lasers, with m u ltiple treatment
sessions,
p rovide a safe method for provid i ng m i ld
i m prove ment of m i l d -to- moderate p h otoda mage with l it­
tle risk of si d e effects. U nfortu nate ly, the p red icta b i l ity of
i m prove ment is u ncerta i n . Some patients do n ot experi­
ence a n y d iscern i b l e benefit even after m u ltiple treat­
ments. In the past 5 years, nona blative fractional lasers
have prod uced e n h a nced results from other forms of
n o n a b l ative res u rfaci ng with m u lt i p l e treatm e nts . These
lasers have a lso p roven to be safe in s k i l led h a n d s . Sti l l ,
thei r efficacy is l i m ited , espec ia l ly w h e n c o m p a red to
a b lative laser resu rfaci ng.
M ore rece ntly, fractional a blative lasers, both carbon
d ioxid e and erb i u m va riants, have been d evelo ped to pro­
vide e n h a nced res u l ts with relatively good safety. The
concept is to provi d e the more aggressive tec h nology of
a b lati o n , but to confi ne potential d ownt i m e a n d s i de
effects b y e m p l oying a fra ctional pattern of tissue d a m ­
age, w h i c h encou rages more ra pid h ea l i ng t i m e s with
fewer side effects. O n ly a fraction of the skin is a blated at
each treatment, as o p posed to trad iti o n a l a b lative res u r­

• Laser h a i r re m ova l
Lasers a re the treatment of choice for permanent red uc­
tion of u nwa nted , pigmented term i n a l hair fol l icles. Laser
h a i r remova l is q u ic k , relatively n o n pa i nfu l , espec i a l l y
compared to e l ectrolysis. Fu rthermore, it ca n cover a fa r
m ore exte nsive a rea of affected s k i n with less pa i n in less
( i e , i m proper spaci ng and overla p) time. An average of
five to seven treatments a re needed for greater tha n 50%
red ucti o n .
Mechan ism of a cti on
Lasers a re based on the selective p h otothermo lysis. The
l ight is a bsorbed
by the
pigment i n
hair fol l i c les.
Therefore, if h a i r fol l i c l es have no pigment ( ie , blond or
gray h a i r ) , lasers d o n ot work. Lasers work best o n t h i c ke r

Figure 17.9 Laser safety. It is important to emphasize that lasers present special safety concerns for physicians, staff, and patients.
Among the risks are ocular injury, fire, electrocution, and dissemination of infectious disease. No lasers should be operated in the
absence of a detailed knowledge of laser safety issues between the physician and the staff. Educating staff members is an essential
component of safe laser practices. Periodic laser safety training is required by many hospitals and remains good practice for private
physician offices as well. (A) Patient and all personnel are wearing protective eyewear. Note gauze is moist to reduce the risk of fire.

• S h a v i n g Cessat i o n
The most s i m ple, i nexpensive, a n d effective treatment for
