Corey S. Maas, MD™, FACS
Fellow – American College of Surgeons
Fellow – American Academy of Facial Plastic and Reconstructive Surgery
Fellow – American Academy of Otolaryngology-Head and Neck Surgery
He performs a modified deep-plane technique known as the Deep Plane SMASplasty Facelift™, which will be discussed in detail below.
we offer advanced techniques in upper and lower blepharoplasty to address aging, puffiness, sagging, and vision obstruction - giving you a brighter, more awake appearance while preserving your individuality.
Upper eyelid surgery removes excess skin and sometimes small amounts of muscle and fat to restore a smoother contour and natural crease.
Dr. Maas performs this popular cosmetic surgery, liposuction, by inserting a cannula (a slender tubular instrument) beneath the skin through a tiny incision.
Open rhinoplasty uses a small external incision across the columella (the tissue between the nostrils), providing full visibility of internal structures. Dr. Maas designs the incision in a discreet W-shaped pattern, minimizing any visible scarring.
When rhinoplasty is combined with internal correction of the septum (to improve breathing), it is referred to as septorhinoplasty.
Performed in-office without anesthesia, non-surgical rhinoplasty is ideal for:
Breast reduction surgery can be performed on an inpatient or an outpatient basis under general anesthesia. It takes about three hours.
Male breast reduction surgery is typically performed as an outpatient procedure under local or general anesthesia. Depending on the composition of the excess tissue, the approach may involve surgical excision, liposuction , or a combination of both.
The results of a mommy makeover can be seen soon after surgery, but it will take a number of months before full results are realized.

Verify three things yourself, whichever practice you choose: certification by the American Board of Plastic Surgery, or Royal College certification (FRCSC) in Canada; whether the operating facility is accredited or the surgeon holds hospital privileges for your exact procedure; and how many of that operation they perform each year. Our guide to choosing a plastic surgeon covers how to check each one.
