Long-term influence of infant periosteoplasty on facial growth and occlusion in patients with bilateral cleft lip and palate

• This retrospective, long-term study evaluated the influence of two different treatment protocols, one including infant periosteoplasty, on facial growth and occlusion in patients with complete bilateral cleft lip and palate (BCLP). Thirty-five patients with records of 5-, 8- and I 6-19-year-olds were included. Sixteen of these received infant periosteoplasty (BCLP-pp) to the cleft alveolus in conjunction with lip repair and a one-stage closure of the palate. The remaining 19 patients with a two-stage closure of the palate did not have an infant periosteoplasty (BCLP-np). The bone formation induced by periosteoplasty in the BCLP-np group was insufficient and both groups had secondary bone grafting to the alveolar clefts before the eruption of the lateral incisor or the canine. Facial growth was evaluated with cephalometry at the recorded ages and dental arch relationships with the Huddart and Bodenham crossbite scores at the age of 16-19 years. Until 19 years a significant retrusion of the maxillary position (SNA) was observed in both groups. At 16-19 years of age there was no significant difference of maxillary protrusion (SNA), intermaxillary position (ANB), maxillary length (ss-pm) or vertical skeletal relationships (ML/NSL, MI/NL) between the two groups. However, a significant difference of the crossbite scores was found. The BCLP-pp group did not show more facial growth problems but more malocclusion and the insufficient bone formation of the alveolar clefts after infant periosteoplasty required a secondary bone grafting.
