    Skin Cancer Reconstruction

    Dr. Gregory Diehl works very closely with our local dermatologists on Long Island to treat skin cancers when they need surgical removal and repair. When a skin cancer is removed, the surrounding skin needs to be repaired so that a scar does not show. Dr. Diehl has extensive experience with reconstruction of skin cancer. Smaller tumors can be treated with relatively straightforward closure techniques. Larger defects require more complicated surgical repair, such as skin flaps or skin grafts, especially when on or around the nose, lips or eyelids.

    Facial Fillers

    Facial Fillers are also referred to as “Non-Surgical” Face Lift. Most of these Facial Fillers last up to a year, and are ideal for people who are not yet ready for a Face Lift Surgery. And the result is immediate, making it quite convenient. Facial Fillers, such as JUVÉDERM® XC, Radiesse®, Belotero® and Restylane®, are products that are designed to fill certain areas on the face to smooth out folds and creases. Some Facial Fillers are designed to be injected in the thinning lips which would give the “Youthful” looking appearance.
