Patients with diseases, problems, and cosmetic changes of the eyelids, brow, mid-face, tear drainage system, and orbit (the area around the eye) are most commonly treated by specialists in oculofacial plastic surgery. If you have problems or concerns in this area, you should look for a doctor who has completed an American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) approved fellowship and has been accepted for ASOPRS membership.

Such membership designates professional recognition and the necessary expertise in these surgical areas. In the United States, there are only a few hundred ASOPRS members, surgeons who have devoted themselves to the sub-specialty of oculofacial plastic and reconstructive surgery. After medical school and internship, ASOPRS surgeons complete four years of accredited eye surgery training and become board certified ophthalmologists.

Then, after two years of extensive accredited oculofacial plastic and reconstructive surgery fellowship training, they must pass the qualifying written and oral examinations, and also have an original scientific investigation and thesis critically reviewed and accepted.
Highlights

read more › Dr. Roger Kohn was born and raised in the Chicago area. It was there that he and his wife met and married. They have two children. Dr. Kohn's undergraduate education was at the University of Illinois where he received a B.A. in Chemistry in only three years. There his academic and leadership accomplishments were honored with his selection to Phi Beta Kappa, Rhodes Scholar nomination, and his receipt of the Patton Award - for the outstanding pre-medical student. Dr. Kohn then attended Northwestern University Medical School where Alpha Omega Alpha (the national medical school academic honorary) honored him with their award for the outstanding original research paper - for his initial and pioneering research on the syndrome of ptosis, blepharophimosis, epicanthus inversus, and telecanthus (subsequently known as Kohn - Romano syndrome, blepharophimosis syndrome).

read more › Your eyes are often the first thing that people notice about you, and are an important aspect of your overall appearance. Your eyelid skin is smooth, but over time, the eyelid skin stretches, the fat bulges forward, and the muscles weaken. The eyebrows may also droop and sag (a condition called brow ptosis). Age, heredity and sun exposure all contribute to this process. Loose or baggy lids detract from your overall appearance and make you look tired or older. When the brow droops, it crowds more skin down over the upper lids and exaggerates the hooding and crow's feet at the outer corners of the eyes, making you look sad, tired, or angry.

read more › Age related changes often reduce the facial fullness associated with our youth. This is particularly evident is the cheek (mid-face) region owing to the effects of gravity and fat deflation. The mid-face extends from the lower eyelids to the nasolabial folds, the normally prominent line extending from the outer corner of the nose to the outer corner of the mouth. As we age, the mid-face slowly and progressively undergoes the effects of descent (due to gravity) and flattening (due to reduced fat volume).

read more › Many age-related changes in the face and eyelids are the result of fat deflation (diminution of fat volume). This results in a diminution of the normal contours of our youth. Lost volume can be restored through volume enhancement - either through the use of injectable fillers (Restylane, Juvederm, Radiese) or surgical introduction of fat via fat repositioning/transfer or fat injections. Fillers have the advantage of being non-surgical and less invasive. Fat introduction has the advantage of greater permanence.

read more › Commonly used facial fillers include hyaluronic acid, a naturally occurring substance already present in your skin (brands include Restylane, Restylane Fine Lines, Perlane, Juvederm, Hylaform ), synthetic microspheres ( Radiesse ), and collagen. Hyaluronic acid fillers typically last six to twelve months and can be used by Dr. Kohn to improve frown lines between the eyebrows, creases at the corner of the mouth (marionette lines), lip shape and/or size, dark circles below the eyes, and depressed facial scars.

read more › Lasers use light energy at various frequencies to vaporize facial lines, wrinkles, certain pigmented skin defects, old acne scars and other scars - significantly reducing these defects. The laser gently removes sun-damaged skin, layer by layer, smoothing out the surface of the skin, while stimulating the regeneration of deeper, healthy skin - tighter and more youthful. It is a relatively bloodless procedure and is performed on an outpatient basis. The ideal laser candidate has fair, healthy, non-oily skin.

read more › Drooping upper eyelids (ptosis) in their various forms is the most common disorder seen by oculofacial plastic and reconstructive surgeons. When the upper eyelid droops, it may block your upper field of vision. Ptosis may range in severity from mild to severe - with excessive covering of your eye and corresponding diminution of your visual field. This condition can be either unilateral or bilateral and reflects a change in the levator muscle (the principal upper eyelid elevator muscle) or much less frequently is the result of deficient nerve supply to this muscle.

read more › The tear drainage system consists of two small openings called punctum, one in your upper eyelid and the other in the lower eyelid. Each of these openings leads into a small tube called the canaliculus which, in turn, empties into the lacrimal (tear) sac located between the inner corner of your eye and your nose. The lacrimal sac then leads into the nasolacrimal duct that passes through the bony structures surrounding your nose. Tears entering this drainage system empty into your nasal cavity. Functionally, when you blink your eyelids push tears evenly across your eyes to keep them moist and healthy.

read more › Traumatic lacerations may result in injury to the face and eyelids. Precise evaluation and repair of such injuries is necessary to insure the best possible function and appearance. When a laceration involves the inner aspect of the eyelids, it is essential to determine whether the lacrimal drainage system has been severed (canalicular laceration) as this requires microscopic repair of the damaged lacrimal structures with placement of a silicone stent (Quickert tube). When a laceration involves the eyelid margin or edge of the lip (vermillion border), it is essential that these be closed in a manner that avoids irregularities such as an eyelid margin notch or lip contour abnormality.
