This kind of repair carries risk of impairment of blood supply to the premaxilla and/or prolabium, and at the same time it cannot ensure adequate stabilization of the premaxilla postoperatively. To overcome these problems, we have developed a unique technique of fixation of the premaxilla. In this paper, we discussing this technique, its advantages, and potential complications associated with it. From 2016, 10 patients aged 4–10 months, with bilateral cleft lip and palate with premaxillary protrusion (≥10 mm) underwent premaxillary setback and cheilorhinoplasty in the same stage. Instead of gingivoperiosteoplasty, a ‘lag screw’ fixation technique was used to stabilize the premaxilla. The follow-up period ranged between 5 and 32 months. In all the cases, we achieved adequate stabilization of the premaxilla. None of the patients had any issue related to the vascularity of the premaxilla or prolabium. There was no impairment in the eruption process of deciduous teeth in the premaxillary segment. Overall aesthetic outcomes of the lip and nose were acceptable. This technique of premaxillary fixation with lag screw gives us...
