Abstract
Introduction:Bony reconstruction of the alveolar process and its adjacent platform largely represents the final step in surgical achievement of functionality and aesthetics in cleft patients. Throughout the years, the success of this procedure has been investigated. The aim of this study was to assess the success rate of autogenous mid-secondary alveolar bone grafting in this setting.Methods and Material:A retrospective cohort study was performed. All cleft patients receiving secondary alveolar bone grafts between 1990 and 2020 were reviewed. Criteria for assessing success were long-term preservation of alveolar bone stock, ability of spontaneous or orthodontic-guided eruption and periodontal health of permanent lateral incisors and canine teeth, absence of exposed root structures of neighbouring teeth, absence of fistula and successful placement of implants. Failure of alveolar bone grafts was indicated by radiographically demonstrable total or near-total graft loss requiring reintervention.Results:A number of 124 patients were included and grouped as those primarily operated following our (two-staged palatoplasty) protocol and those receiving cheilorhinoplasty and palatoplasty (one-staged) at other centres. Given the limited cohort size, no complex statistical analysis was performed. In the first group of 64 patients 12 experienced complications (Veau III, eight/36; Veau IV, four/18). In the second group of 60 patients, 12 experienced complications (Veau III, six/37; Veau IV, six/17).Discussion:Our surgical protocol using anterior iliac bone grafts for secondary alveolar reconstruction achieved good results, comparing favourably with previous literature.
