Introduction: Cleft osteotomies are usually performed in the late teen period to correct dento-facial
deformities due to lack of growth of the cleft maxillae and/or scarring around the
cleft sites. This procedure is technically demanding due to the difficulty in mobilisation
of the maxillae following the osteotomy which is usually performed at Le Fort I level.
Planning these cases is tedious and must take into account the high risk of relapse
associated with such cases due to the degree of scarring around the cleft site and
the tight soft tissue envelope surrounding the maxillae. This Unit operates on about
10–15 cases per annum. Relapse of the maxillae to a position not co-incident with
the pre-operative planned position is not uncommon due to the above reasons.
