title: Lip enhancement: surgical alternatives and histologic aspects.
abstract: This study included 66 consecutive patients, 58 women and 8 men, who underwent 86 surgical procedures on the lips during 1989-1998. Lip enlargement was performed in 59 patients, and lip reduction was performed in 7 patients. Indications were purely aesthetic in 61 cases and reconstructive in 5 cases. The following surgical techniques were used for lip augmentation: implantation of crystal silicone, polyacrylamide hydrogel, Gore-Tex tubes, autologous fat, and dermis-fat graft. A new instrument originally designed by the author, the dermis-fat graft passer, significantly speeded up and facilitated execution of the latter procedure. Other operations included V-Y plasty, lip lifting by buffalo horn excision, lip lengthening by frenulum plasty, and lip reduction by wavy tangential excision. Eighty-six percent of patients could be followed up; the mean length of follow-up was 4.2 years. Use of silicone microparticles (Bioplastique) was abandoned because of the tendency for lumping. Polyacrylamide gel is promising because of its ease of use, and Gore-Tex tubes are promising because of their ability to create and accentuate the Cupid's bow form for the upper lip. However, these products are new, and follow-up studies with longer observation times are needed to reach definite conclusions. Of these studied methods, autologous fat transplant was found to be particularly useful for enlargement and restoration in cases of age-related atrophy of the lips and perioral tissues. Dermis-fat grafting was the most efficient, versatile, and reliable method of lip enlargement. Long-term survival of transplanted autologous tissues was confirmed by histologic studies of biopsy specimens.
