Analysis of the role of flap perfusion on bone graft outcomes using noninvasive monitoring

Michael Han headshot

Dr. Michael Han is currently Assistant Professor and Residency Program Director at University of Illinois Chicago College of Dentistry’s Oral and Maxillofacial Surgery Department. He received his specialty and fellowship training at University of Washington and Dalhousie University, respectively. His clinical and research focuses are in 3D imaging analysis and surgical planning, and has authored numerous publications in peer-reviewed journals and textbooks in Oral and Maxillofacial Surgery and dentistry.


Background and Purpose:
The outcomes of nonvascularized hard tissue grafts in the maxillofacial region varies, with little known about risk factors for clinical failure. In addition, less is known about the precise level of significance of the perfusion of the flap in the success of bone grafting procedures. The purpose of this study is to measure the influence of perioperative flap perfusion on outcomes of bone grafts in the maxillofacial skeleton.

Study Design, Materials and Methods:
This will be a prospective cohort study involving subjects undergoing osseous reconstruction of the maxillofacial skeleton via non-vascularized bone grafting techniques at the University of Illinois Chicago/Health Sciences System. Patients planned for osseous reconstruction of the jaws will be considered potential subjects and will be recruited, based on the inclusion criteria of age greater than or equal to 18 years. Exclusion criteria will include history of osseous or soft tissue surgeries or radiation in the area(s) of interest.
