BiographyDr. Leonard Kaban is internationally recognized in the field of craniofacial deformities -- e.g hemifacial microsomia -- pediatric oral and maxillofacial surgery, jaw tumors in children, and minimally invasive surgical techniques.

Currently chief of oral and maxillofacial surgery and Walter C. Guralnick professor and chairman of oral and maxillofacial surgery at Harvard School of Dental Medicine (HSDM), Dr. Kaban attended Queens College,  received his DMD from HSDM and MD from Harvard Medical School.  He is a Diplomate of the American Board of Oral and Maxillofacial Surgeons, American Board of Medical Examiners and a Fellow of the American Association of Oral and Maxillofacial Surgeons and American College of Surgeons.

As speaker and visiting professor, Dr. Kaban has crisscrossed the globe.  He is known for treatment of children with craniofacial abnormalities, jaw deformities, jaw tumors, TMJ deformities, salivary gland disease, secondary cleft lip/palate deformities, obstructive sleep apnea, micrognathia and facial trauma. His research includes the development of distraction osteogenesis for mandibular advancement, bone wound healing and tissue engineering.  He has received many honors, including the HSDM Distinguished Alumni Award, AAOMS Research Recognition Award, Donald Osborn Outstanding Educator Award, and Harvard Medical School Award for Mentoring Women Faculty.

Dr. Kaban's research interests are integrated with his clinical practice.  He works avidly to reduce the surgical trauma, enhance the quality of healing, and improve the outcomes of facial surgery.  He has also been working on the biology of giant cell tumors of bone in an effort to develop medical therapies for these aggressive jaw lesions in children.

Dr. Kaban is author or co-author of over 270 scientific publications and five books, including the text Pediatric Oral and Maxillofacial Surgery.

ResearchDr. Kaban founded the Skeletal Biology Research Center (SBRC) in 1994, in order to promote reduced surgical morbidity and better clinical outcomes for patients with traumatic injury, congenital and acquired anomalies, and diseases of the face and jaw.  Working in partnership with academia and industry, the SBRC has contributed important advances to the field of oral and maxillofacial surgery, including refinement of minimally invasive surgical techniques for OMS, engineering of a distraction device for curvilinear movement along the face and jaws, tissue engineering, and computerized three-dimensional treatment planning.
