F.D.A. Panel Backs Breast Implants From One Maker
Federal advisory panel votes to approve silicone breast implants from Mentor Corp day after it rejected similar application from Inamed Corp; most panel members say they are comfortable with long-term safety of Mentor devices, and most dismiss concerns that ruptured implants cause kind of serious diseases that some women's groups have listed; diverging votes send mixed message to Food and Drug Adm, making predictions about what it would decide impossible; many experts say FDA has toughened oversight of device and drug manufacturers in recent months; agency generally follows advice of its advisory panels; three-day hearing on implants included more than 160 witnesses, including dozens of women who claim implants sickened them and dozens of other women who pronounce silicone implants safe boost to their self-esteem; nearly all studies have found no link between silicone implants and serious disease (M)
