Ten-year experience using injectable silicone oil for soft tissue augmentation in the Philippines.
BACKGROUND
No ideal, permanent filler is approved by the U.S. Food and Drug Administration. Repeated injections of new temporary fillers make this cosmetic procedure expensive.


OBJECTIVE
To show that silicone oil is effective, safe, economical, and permanent.


METHODS
The age, sex, number, indications, sites, adverse reactions, total amounts injected, and clinical cosmetic results of 206 cases were tallied.


RESULTS
Females (82%) outnumbered males (18%). The majority were in the 21- to 30-year age group. Fifty-five percent had acne scars, 42% nasolabial grooves, 13.5% marionette lines, 12.6% glabellar lines, 9.8% postvaricella scars, 9.3% inframalar depressions, 1.8% post-traumatic scars, 1.4% lipodystrophy, 1% lip augmentation, 0.9% sleep lines, and 0.4% contour defect. Fifty-one percent had < or = 0.5 cc, 22% 1 cc, 7% < or = 1.5 cc, 7% < or = 2 cc, and 12% >2 cc. Clinical improvement was graded excellent (76-100%), good (50-75%), fair (26-50%), and poor (< 25%). Seventy-two percent had excellent results, 18% good, 2% fair, and 0.5% poor. Seven percent were lost to follow-up. Two percent (n=5) had transient erythematous papules lasting 2 to 6 weeks, with the exception of two patients.


CONCLUSIONS
Silicone oil injected with the correct indications and techniques and with microdroplet injections is a safe, economical, and permanent dermal and subcutaneous filler. Rare permanent erythematous papules and transient ecchymoses appear on deep dermal injections.
