Prof. Patel did extended postgraduate fellowships in Europe and in the United States and trained with some of the best surgeons in the world. Prof. Patel's expertise is in the management of disorders involving eyelids, periorbital tissues, lacrimal system and facial bones including fractures and in all cosmetic procedures of the face. He has designed and refined several surgical procedures and instruments. His clinical research interests include thyroid disease, optic nerve disorders, orbital and eyelid tumors, blepharospasm, lacrimal surgery and facial cosmetic surgery.He has developed and published many cosmetic facial surgical procedures, including procedures for the brows, upper and lower eyelids, cheeks and the lower face and neck.The division has been a pioneer in research and development of techniques for the management of ocular and facial disorders, orbital malpositions, thyroid eye disease, optic nerve surgery, lacrimal problems and tearing, eyelid and orbital tumors, and the treatment of orbital and facial fractures. The division developed the use of Botulinum toxin which is also used in the treatment of facial wrinkles and frown lines.Many of the cosmetic and reconstructive surgical procedures utilized have been developed by the division including ptosis repair, upper blephs, endoscopic brow elevation, transconjunctival lower blephs, modified face and neck lifts and fat grafts to the face for cosmetic and reconstructive purposes. Small incision endoscopic brow elevation and midface lifts allow aesthetic improvement in many patients who previously would not have been candidates for surgery. Procedures including chin and cheek augmentation and facial liposculpture are directed at restoring, and enhancing the architecture and support of the face and eyelids; procedures that remove supportive structures are avoided.
