"EVALUATION OF EFFICACY OF SUBCILIARY APPROACH FOR THE TREATMENT OF INFRAORBITAL BONE FRACTURES-A CLINICAL STUDY"

The zygomatic bone is an essential element of facial configuration as it constitutes the prominence of the cheek bone. Because of its prominence and exposed location, the zygoma is highly susceptible to fractures in facial trauma.

The zygoma is geometrically unique because it articulates with four bones - the frontal, temporal, maxilla and sphenoid. Zygoma fractures are typically described as being tetrapod. zygomatic complex fractures present challenging diagnostic and reconstructive problems for the surgeon.

Anatomic reduction of lateral, inferior orbital rims and orbital floor are necessary to reestablish facial symmetry and position of the globe and to restore normal sensation to the structures innervated by the infraorbital nerve.

The increasing emphasis on open reduction and bone grafting techniques in the treatment of facial fractures needs a search for incisions which provide good exposure of fracture sites and minimal cosmetic deformity.

The lower orbital rim and orbital floor can be exposed transcutaneosly through the subciliary, subtarsal and infraorbital incisions or by means of transconjunctival incision with lateral canthotomy.

The conventional subciliary incision which is a kind of transcutaneous incision was first described by converse in 1944. This approach spares the conjunctiva, bypasses the transconjunctival related complications, and eliminates the need for a lateral canthotomy. Furthermore the incision can be extended either to the medial or lateral sides to explore any associated fracture.

In this study the following parameters are being studied:

1.Time duration of the surgery

2.presence of visible postoperative scar formation by using modified vancouver scar scale

3.presence of scleral show using ectropion grading scale
