Abstract: Le Fort 1 osteotomy is a common procedure in cleft orthognathic surgery. However, the stability of the segmentalized maxillary bone components remains a major issue as it contributes to the long term successful surgical outcome. Based on the literature, the unilateral cleft anterior segment has the tendency to relapse back due to the high soft tissue tension and lack of rigidity of the device used for example acrylic splint or an archbar to maintain the surgically corrected maxillary arch position and alignment. An eighteen year old Malay male presented with a repaired left unilateral cleft lip and palate came complaining of anterior open bite on the left cleft side. He underwent unilateral segmental Le Fort 1 osteotomy on the cleft segments and the arch was stabilized with a customized Cobalt-Chromium (Co-Cr) palatal bar and stainless steel wire. Post-operative 1 year and 8 months later shows good healing with no relapse. Our novel technique of using Co-Cr palatal bar provide adequate post-operative support and can be applied by surgeons in segmental cleft orthognathic surgeries.
