Achieving the Optimal Aesthetic Benefit While Correcting Midface Deficiency: Utilizing A High Winged Le Fort I in Cleft and Craniofacial Patients.

Abstract

Craniofacial anomalies are congenital disorders that affect the cranium and facial bones, with cleft lip and palate being the most common. These anomalies are often associated with abnormal development of pharyngeal arches and can result in the development of class III malocclusion and severe maxillary retrusion. Current treatment includes orthodontic decompensation and Le Fort I osteotomy to correct the maxillomandibular relationship. However, the traditional Le Fort I (LFI) advancement does not fully address the lack of skeletal volume in the midface. The high winged Le Fort I osteotomy (HWLFI) is an excellent surgical option for simultaneous correction of the midface deficiency and malocclusion while restoring optimal esthetic convexity. A retrospective chart review was conducted to include all cleft and craniofacial patients who underwent HWLFI advancement from 2002 to 2018. Patients had a minimum of 12 months of follow-up. Patient data and complications were reviewed. Standardized facial photographs were analyzed for esthetic improvement, occlusion, and beneficial salutary effects on the midface. Forty-three patients met the inclusion criteria. The mean age at surgery was 18.9 years. The mean follow-up was 32 months. Early complications included infection (9.3%) and temporary nerve paresthesia (2.3%). Late complications included infection (6.5%), wound dehiscence (4.3%), and painful hardware (2.3%). One patient (2.3 percent) had clinically significant relapse that required surgery. Postoperatively, patients demonstrated excellent midface projection and correction of the skeletal malocclusion. The HWLFI advancement significantly improves both the malocclusion and esthetic concerns of cleft and craniofacial patients by reestablishing maximal midfacial support. Important advantages of the HWLFI are avoidance of alloplastic implant use and extensive and potentially unstable surgical procedures that increase orbital volume.
