Expert testimony is needed to prove that liposuction of the cheek was not substantially the same as liposuction to the chin and jowl region, a Philadelphia common pleas court judge has ruled.

Without such expert testimony, plaintiff Marian Moore failed to provide sufficient evidence to show that cosmetic surgeon, defendant Dr. John H. Moore, had committed medical battery, the court said. Judge Howland W. Abramson granted a non-suit after the close of the plaintiff’s case. Marian Moore is not related to John Moore.
