Procedures and techniques named

  • Deep Plane SMASplasty FaceliftHe performs a modified deep-plane technique known as the Deep Plane SMASplasty Facelift™, which will be discussed in detail below.
  • Blepharoplasty: upper and lower techniques address puffiness, vision obstructionwe 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.
  • Blepharoplasty: upper eyelid surgery removes skin, muscle, fatUpper eyelid surgery removes excess skin and sometimes small amounts of muscle and fat to restore a smoother contour and natural crease.
  • Liposuction: cannula inserted through tiny incisionDr. Maas performs this popular cosmetic surgery, liposuction, by inserting a cannula (a slender tubular instrument) beneath the skin through a tiny incision.
  • Rhinoplasty: open approach, W-shaped columella incisionOpen 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.
  • SeptorhinoplastyWhen rhinoplasty is combined with internal correction of the septum (to improve breathing), it is referred to as septorhinoplasty.
  • Rhinoplasty: non-surgical performed in-office without anesthesiaPerformed in-office without anesthesia, non-surgical rhinoplasty is ideal for:
  • Breast reduction: general anesthesia, about three hoursBreast reduction surgery can be performed on an inpatient or an outpatient basis under general anesthesia. It takes about three hours.
  • Gynecomastia: outpatient, local or general anesthesiaMale 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.
  • Mommy makeover: full results take monthsThe results of a mommy makeover can be seen soon after surgery, but it will take a number of months before full results are realized.

Before you book here

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.
