About

Dr. Marc Tewfik is a fellowship-trained otolaryngologist—head and neck surgeon in Montreal, with a sub-specialty practice in rhinology: the medical and surgical care of the nose and sinuses. He completed his medical degree, otolaryngology residency and a Master of Science at McGill University, then trained in rhinology and skull base surgery at the University of Adelaide in South Australia under Professor Peter-John Wormald. He is an Associate Professor in the Department of Otolaryngology—Head and Neck Surgery at McGill and directs the university's Advanced Rhinology and Endoscopic Skull Base Fellowship. His private practice focuses on chronic sinus disease and nasal airway obstruction, including several office-based procedures performed under local anaesthetic.

Clinical Focus & Specialties

  • Chronic Sinus Disease: Endoscopic sinus surgery and endoscopic removal of nasal polyps for chronic sinusitis, recurring sinus infections, facial pressure, and nasal congestion that has not settled with medical treatment.
  • Nasal Airway Obstruction: Septoplasty, turbinate reduction, and nasal valve support implants for a deviated septum, chronic blocked nose, and difficulty breathing through the nose.
  • Chronic Rhinitis & Runny Nose: Posterior nasal neurectomy and cryotherapy of the nasal nerves for persistent runny nose, post-nasal drip, and congestion from allergic and non-allergic rhinitis.
  • Ear Pressure & Smell Loss: Eustachian tube balloon dilation for ongoing ear fullness and pressure, and platelet-rich plasma (PRP) injection for loss of smell.
  • Office-Based Procedures: Several of these procedures, including polyp removal, are offered in the office under local anaesthetic rather than in an operating room.

Dr. Tewfik sees patients at ENT Specialty Group in Westmount, a Montreal otolaryngology clinic founded in 2004 covering nasal and sinus disease, ear, voice, thyroid, and head and neck care. Surgical procedures are performed at Ville-Marie Surgery Institute on avenue du Docteur-Penfield in downtown Montreal, a private surgical facility with fully equipped operating rooms and a dedicated surgical and nursing team.
