Training and board certification
Per his bio page: medical degree from the University of Ottawa (1987), graduating first in his class (Magna Cum Laude, Gold Medalist); B.Sc. in mathematics and engineering from Queen's University, Kingston, Ontario (1982) (doctor bio). He completed a surgical internship at Ottawa Civic Hospital, then plastic surgery residency at the University of Toronto (1988-1993), a one-year microsurgery fellowship focused on head, neck and craniofacial surgery at the University of Toronto (1993-1994), and a one-year hand surgery fellowship in the Department of Orthopedic Surgery at SUNY Stony Brook (1994-1995). He is a Diplomate of the American Board of Plastic Surgery (since November 2003, most recently recertified through 2034) and holds the Certificate of Added Qualification in Surgery of the Hand from the same board (since August 2004). He is a Fellow of the American College of Surgeons (FACS, since 1999) and a Fellow of the Royal College of Physicians and Surgeons of Canada (FRCS(C), since 1994). He is a tenured Professor of Surgery at Stony Brook Medicine and formerly served as Chief, Division of Plastic Surgery, SUNY Stony Brook (2000-2023) and Interim Chairman, Department of Surgery, SUNY Stony Brook. He is past President of the Ontario Society of Plastic Surgeons. The bio page credits him with nearly 100 peer-reviewed publications and book chapters, and as co-inventor and patent holder on a method to treat cellulite and on "DISC," a method to optimize the use of Botox.
Eyelid surgery work
The practice's blepharoplasty page, written at the group-practice level rather than attributed to one surgeon, describes upper blepharoplasty as removing excess skin and fat through an incision in the natural crease of the upper eyelid, and lower blepharoplasty as addressing under-eye bags and dark circles through a transconjunctival (internal) incision or a small incision below the lash line (source). The page describes ptosis as a weakening of the muscle that lifts the eyelid, treated with "functional blepharoplasty" that tightens or repairs the levator muscle, distinct from cosmetic eyelid surgery. Surgery is typically outpatient, one to three hours, performed in-office for upper lids or in an AAAASF-accredited suite for lower or combined procedures, with PRO-NOX (50% nitrous oxide/50% oxygen) offered for comfort. A separate brow lift (forehead lift) page is also listed in the facial-procedures menu (source).
The blepharoplasty before-and-after gallery page shows multiple real patient photo pairs (source); the gallery is shared across the practice's surgeons rather than filtered to Dr. Dagum specifically.
Other procedures
Dr. Dagum's individual bio describes a career spanning hand and microsurgery, craniofacial surgery (including cleft palate), and cosmetic surgery, and states he led a team of hand surgeons in one of the world's first double hand replantations in 2005 (doctor bio). He has sponsored children from overseas with craniofacial anomalies for reconstructive surgery and serves on the boards of Smile Rescue Fund for Kids and Blanca's House.
Insurance and cost
The eyelid-surgery FAQ states cosmetic blepharoplasty is not covered by insurance, but insurance may cover a portion of the procedure if ptosis is obstructing vision, pending a functional evaluation (source). No eyelid-surgery prices are published; the FAQ states cost depends on the procedure and is quoted during consultation.
