A retrospective study on liquid injectable silicone for lip augmentation: long-term results and patient satisfaction.

Various injectable fillers are used for soft-tissue augmentation, including liquid injectable silicone [LS]. This study evaluates patient satisfaction and long-term results after [LS] for lip augmentation. A total of 179 patients, who received medical grade [LS] for lip augmentation, were included in the study. The microdroplet technique was used in all cases, and not more than 1cc per lip per session was injected. The follow-up period varied from 3 years to 7 years. The long-term results (3-7 years), satisfaction level and complications were evaluated. As many as 171patients had upper lip injections and most had 1cc silicone injected. Eighty-seven had lower lip injections. Eight-five percent of the patients considered having excellent or good results. Most (76%) patients considered their lips to be as soft as before treatment. No complications were recorded for 91.1% of the patients. Complications encountered by the rest were minor and temporary, such as ecchymoses and haematoma in 6.2% and invisible but small palpable nodules in 2.2%. In our experience, the injection of [LS] by the microdroplet technique is safe for a period of 3-7 years, gives high satisfaction to the treated persons and has minimal complications.
