Most of unilateral complete cleft lip and palate patients have midfacial deficiencies probably due to repeated operation. In these cases, maxillary protraction for maxillary growth is required for the harmonious facial esthetics and keep normal functions. So we used miniplate anchorage to treat four cleft patients with midfacial deficiencies. 7 hole titanium miniplates were placed to the thick zygomatic buttress areas with 3-4 screws. Clefted alveolar portion were splinted with arcrylic resin for the even protraction of maxillary segments. After 3~4 weeks, the orthopedic forces was applied 12 to 14 hours per day. In all cases, there was significant forward movement of the maxilla because the miniplate provides enough anchorage without inflammations or mobililties. Therefore, this method can be an effective strategy for cleft patients with midfacial deficiencies.
