OBJECTIVE: To determine the outcome of secondary alveolar bone grafting (SABG) in a series of consecutive patients with clefts involving the alveolus.
DESIGN AND SETTING: Retrospective cohort study of consecutive operations performed between June 2011 and September 2016 by a single surgeon at a single United Kingdom cleft center.
PARTICIPANTS: A total of 160 patients with a cleft/s involving the alveolus, inclusive of syndromic patients and those with atypical facial clefts.
INTERVENTIONS: A standard protocol involved an oral hygiene program, pre-surgical orthodontics where necessary and autologous bone grafting from the iliac crest.
MAIN OUTCOME MEASURE(S): The Kindelan bone-fill index was used to evaluate success using occlusal radiographs. Weighted Cohen's kappa coefficient was used as a measure of intra- and inter-rater agreement. Fisher's exact test was used to examine the effects of type of cleft, pre-surgical orthodontics or age at time of SABG on radiographic outcome.
RESULTS: There were 200 SABGs assessed. Mean age at time of SABG was 9.1 years old (SD 1.1) with 99% (n = 198) of grafts deemed successful. There were two failures where re-graft was performed successfully during the study period. A grade 1 outcome was achieved for 92.5% (n = 185) of grafts and this did not appear to be affected by type of cleft (P = .290), pre-surgical orthodontics (P = .380) or age at time of SABG (P = .081).
CONCLUSIONS: The high success rate reported in this study supports the favorable outcomes of a high-volume cleft surgeon. These findings can be used for comparative audit with similar units providing cleft care.
