Background:
Asymmetry of the infraorbital rim can be caused by trauma, congenital or acquired disease, or insufficient reduction during a previous operation. Such asymmetry needs to be corrected because the shape of the infraorbital rim or midfacial skeleton defines the overall midfacial contour.
Methods:
The study included 5 cases of retruded infraorbital rim. All of the patient underwent restoration of the deficient volume using polyethylene implants between June 2005 and June 2011. The infraorbital rim was accessed through a subciliary approach, and the implants were placed in subperiosteal space. Surgical outcomes were evaluated using preoperative and postoperative computed tomography studies.
Results:
Implant based augmentation was associated with a mean projection of 4.6 mm enhancement. No postoperative complications were noted during the 30-month follow-up period.
Conclusion:
Because of the safeness, short recovery time, effectiveness, reliability, and potential application to a wide range of facial disproportion problems, this surgical technique can be applied to midfacial retrusion from a variety of etiologies, such as fracture involving infraorbital rim, congenital midfacial hypoplasia, lid malposition after blepharoplasty, and skeletal changes due to aging.
